The image is Circuit board indicator led in NEWs of China QUEENDOM Company.

Introduction Circuit board indicator LEDs are an economical and straightforward solution for providing onboard power, control, or activity indications in many different types of electronic systems. These lighting components are used to indicate power status, device on/off conditions, and to show when a particular feature is activated. What are circuit board indicator LEDs? Circuit board indicator LEDs are small, low-power devices typically used to provide visual feedback in electronic devices. They can be used to alert a user that power is present, inform the user when a device is turned on, indicate the operation of certain functions, or even provide light for a display. They come in various colors and sizes, but they typically consist of a base, a light-emitting diode, and a lens. The lens can be clear, diffused, color-tinted, or even reflective, depending on the application. The base can be either soldered directly to the circuit board or mounted on a bracket to produce a remote indicator. How do they work? Circuit board indicator LEDs are typically used in pulsed application, meaning that they turn on and off quickly. This is because the LEDs require current flowing through them in order to produce light, and current dissipates over time unless regularly refreshed. So when a circuit board indicator LED is turned on, it typically draws a certain amount of current, and then automatically shuts off after a certain amount of time. This process can repeat over and over, depending on the application. What are the benefits of using them? The primary benefit of using circuit board indicator LEDs is their low cost, simple design, and ease of use. They are extremely low-power and reliable, and can be used to indicate the status of a device or a function of a device. They also provide a visual display that can provide feedback to users and alert them to changes in the system. How to choose the right one for your project? When choosing the right circuit board indicator LED for your project, there are a few things to consider. First, you need to think about what type of light output you need. Depending on the application, you may need a bright, diffuse light, or a more subtle, dim light. You also need to consider the size, shape and voltage rating. Choose the LED with the correct voltage and current rating for your application. Finally, you need to think about the color you need. Different colors have different meaning and indicate certain functions. Conclusion Using circuit board indicator LEDs is an effective, reliable, and cost effective solution to many situations. They provide visual cues that information can help guide users and show the current status of a device. But when choosing the right LED for your project, you need to consider the size, voltage, color, and brightness of the LED, in order to ensure that it meets your needs.  

What is a 7-segment display?

The image is --segment display in NEWs of China QUEENDOM Company.

A 7-segment display is an electronic device that can be used to display numbers and some letters. Different letters/numbers can be represented by connecting different pins on the display to batteries that turn on the LED in parallel. A 7-segment display is an older optoelectronic display device primarily used to display letters and numbers. As the name suggests, these displays consist of seven sections that can be switched on and off to display the desired number or letter. Each part of the display is usually a single LED or liquid crystal. These displays are widely used in electronic counters, digital clocks, home appliance displays, simple calculators, automobiles, and various electronic devices that display digital data. Why are 7-segment displays important? So it’s all about seven-segment displays, types of seven-segment displays, and how to control the position of a seven-segment display, but seven-segment displays are still a great place to start learning about display technology. For this reason, common-anode seven-segment displays are very popular because many logic circuits draw more current than they can source. These displays are not a direct circuit replacement for common anode displays as this is the same as connecting the LEDs in reverse so no light emission will occur. According to the displayed decimal number, the corresponding LED group is forward biased. For example, to display the number 0, we need to light up the segments corresponding to the remaining a, b, c, d, e, f. The numbers 0 to 9 can then be displayed with a seven-segment display. How do 7-segment displays work? Seven segment display interfaced with Arduino is used to easily display 0 to 9 digits. Therefore, these indicators are mostly used in larger electronic projects such as alarm clocks, object counters, timer circuits, digital clocks, etc. A 7-segment display with 7 LEDs arranged to display the numbers 0-9. The 7-segment display is connected to the microcontroller like an LED (ie in series with a current limiting resistor). The only difference is that they have 8 pins instead of 2, since each of the 7 LEDs has its own pin as well as a common cathode or anode pin.

The image is led tube in NEWs of China QUEENDOM Company.

LED light tube uses light-emitting diodes as light sources, which have higher luminous efficiency, more energy-saving, longer service life, and are more environmentally friendly. Become the most ideal product to replace fluorescent tubes at the present stage. The traditional fluorescent tube is also called a fluorescent lamp. There is a filament at each end of the lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. The gas between the two filaments emits ultraviolet rays when conducting electricity. Make phosphors emit visible light. Due to the heavy metal pollutant “mercury”, the scrapped fluorescent tubes pollute the environment very seriously. Introduction LED fluorescent tubes are the same as traditional fluorescent tubes in terms of size and diameter. There are three types of lengths: 60cm, 120cm, and 150cm. 10W LED fluorescent lamps are brighter than traditional 40W fluorescent lamps, 16W LED fluorescent lamps are brighter than traditional 64W fluorescent lamps, and the brightness of LED fluorescent lamps is especially softer Make it easier for people to learn.

Service Life Because the LED light tube adopts the light-emitting mode of solid light source, the life span mainly depends on the solid LED light source and the driving heat dissipation part. At present, the life span of LED light source has reached more than 100,000 hours. The heat dissipation has basically reached a relatively ideal state. The life of high-quality LED light tubes available in the market basically reaches 10,000-50,000 hours, which is almost 10-50 times that of fluorescent tubes. LED fluorescent tubes save more than 80% of electricity and are almost maintenance-free. There is no problem of frequent replacement of lamp tubes, ballasts, and starters. The cost saved in about half a year can be exchanged for the cost.

What is a SMD LED?

The image is smd led in NEWs of China QUEENDOM Company.

SMD LED (Surface-mounted devices) is a led chip mounted on the surface of a PCB (printed circuit board). Its light-emitting principle is to pass current through compound semiconductors, and through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of light.They are produced using Surface Mount Technology (SMT).

What is an infrared LED?

The image is IR LED in NEWs of China QUEENDOM Company.

Infrared light-emitting diode is a diode that emits infrared rays, and is usually used in remote controls and other occasions. Commonly used infrared light-emitting diodes are similar in shape to light-emitting diodes (LEDs) and emit infrared light. Directional Properties The emission intensity of infrared LEDs varies depending on the emission direction. When the direction angle is zero, its radiation intensity is defined as 100%. When the direction angle is larger, its radiation intensity is relatively reduced. If the emission intensity is half of its direction angle from the optical axis, its value is half of the peak value. This angle is called the direction half-value angle, and the smaller the angle is, the more sensitive the directivity of the device is. Generally, infrared light-emitting diodes are equipped with lenses to make their directivity more sensitive Distance Characteristic The radiation intensity of infrared light-emitting diodes varies with the distance on the optical axis and also with the different light-receiving elements. It is the change of the incident light amount of the light-receiving element and the distance from the infrared light-emitting tube that have certain characteristics. Basically, the amount of light is inversely proportional to the square of the distance, and it is related to the different characteristics of the light receiving element. When emitting infrared rays to control the corresponding controlled device, the controlled distance is proportional to the emission power. In order to increase the control distance of infrared rays, infrared light-emitting diodes work in a pulsed state, because the effective transmission distance of pulsating light (modulated light) is proportional to the peak current of the pulse, and the emission distance of infrared light can be increased by increasing the peak Ip as much as possible. The way to improve Ip is to reduce the pulse duty cycle, that is, to compress the pulse width T. Generally its use frequency is below 300KHz. Receiving Method There are two ways to emit and receive infrared rays, one is direct and the other is reflective. The direct type means that the luminous tube and the receiving tube are relatively placed at the two ends of the transmitter and the controlled object, with a certain distance between them; the reflective type means that the luminous tube and the receiving tube are placed side by side, and the receiving tube is always without light at ordinary times, only in the infrared light emitted by the luminous tube. When the light meets the reflector, the receiving tube will only work when it receives the reflected infrared light.

What is a High Power LED?

The image is high power led in NEWs of China QUEENDOM Company.

High-power LEDs refer to light-emitting diodes with high rated working power. The power of ordinary LEDs is generally 0.05W, and the working current is 20mA, while high-power LEDs can reach 1W, 2W, or even tens of watts, and the working current can range from tens of milliamperes to hundreds of milliamperes. Working Principle Light-emitting diode (LED) is a solid-state device that can convert electrical energy into light energy. Its structure is mainly composed of PN junction chips, electrodes and optical systems. The basic working principle of LED is a process of electro-optic conversion. When a forward bias voltage is applied to both ends of the PN junction, due to the reduction of the PN junction potential barrier, the positive charges in the P region will diffuse to the N region, and the electrons in the N region will also flow to the N region. The P region diffuses, forming a non-equilibrium charge accumulation in the two regions at the same time. Since the minority carriers generated by current injection are relatively unstable, for the PN junction system, the non-equilibrium holes injected into the valence band will recombine with the electrons in the conduction band, and the excess energy will radiate outward in the form of light. The greater the energy difference between electrons and holes, the higher the energy of the resulting photon. If the energy level difference is different, the frequency and wavelength of the light produced will be different, and the color of the corresponding light will be different.   Comparison of high power and standard power LED products   Simplify the design process The design process required for standard LED arrays is much simpler than that required for high-power technologies due to considerations that greatly simplify thermal management. In our theoretical example, driving a 1W LED requires 350mA, while a standard array of six LEDs requires only 120mA. High power technology requires the use of heat sinks and metal core PCB boards to ensure that high junction temperatures are avoided resulting in loss of efficiency, reduced lifetime or discoloration. Because standard LEDs do not require the use of heat sinks, metal core printed circuit boards (MCPCBs), capacitors or resistors, these LEDs are easier to design, test and manufacture. This simplified process not only saves time and money in the production process, but also speeds up time to market. Cost saving High-power LEDs require thermal management, which greatly increases the cost of the LED. During the design process, the most expensive addition is the heat sink. Heat sinks can be made from a variety of metal materials, from relatively inexpensive aluminum to more expensive materials that conduct electricity better, such as copper and silver. These expensive materials can lead to an increase in the cost of high-power products by US$1 to US$10, which can be avoided by standard LED devices. Likewise, high-power LEDs also require the use of MCPCBs as another passive cooling technique to control junction temperature. Because the MCPCB material has better thermal conductivity, these boards dissipate heat more efficiently than the cheaper FR4 PCBs used by standard LEDs. However, its cost can be as high as 5 times the cost of FR4 PCB. Cost savings of up to 60% can be achieved by using cheaper FR4 PCBs, eliminating the need for expensive heat sinks, and simplifying design considerations. Save space Standard LEDs are often the best choice when the interior space constraints of a device are very large. As mentioned above, high power LEDs require the additional use of heat sinks and overall space-intensive cooling techniques. Its first task is to create more surface area for cooling by convection and radiation. Larger surface area can help reduce heat more effectively, but it also increases the volume of high-power LEDs. This adds design hurdles for smaller spaces and smaller products. Standard LED arrays typically do not require the space-consuming drivers, capacitors, and resistors required for high-power LEDs, resulting in space savings of up to 50%. For space-constrained applications, standard LED arrays can provide the same brightness as high-power LEDs while saving space.

What is a UV Flood Light?

The image is UV flood light in NEWs of China QUEENDOM Company.

What is a floodlight? Floodlight is the most widely used light source in the production of renderings, and standard floodlights are used to illuminate the entire scene. Multiple flood lights can be applied to a scene. In order to produce a better effect, the light bulb for shooting is packed into a large reflective umbrella for use as a high-brightness diffused light source. Although it is indispensable for lighting in the studio, it can also be regarded as one of the light sources with good lighting effects for general amateur indoor photography. Floodlights are not spotlights, projection lights, or spotlights. Floodlights produce highly diffuse, non-directional light rather than a well-defined beam, resulting in soft and transparent shadows that fade more slowly when used for object lighting than when illuminated by spotlights. There are even flood lights whose illumination fades off very slowly, appearing as a light source that does not cast shadows. Spotlights, on the other hand, cast a directional, well-defined beam of light that illuminates a specific area. How floodlights work? The traditional electric light source, whether it is an incandescent lamp or a high and low pressure gas discharge lamp, is composed of a glass bulb and a filament. Electric energy enters the bulb through the filament and is converted into light energy. The floodlight is by inductively coupling high-frequency electromagnetic energy into the bulb, so that the gas in the bulb avalanche ionizes to form plasma, and when the excited atoms of the plasma return to the ground state, they spontaneously radiate 245nma ultraviolet rays, Phosphors are excited by ultraviolet light to emit visible light. Floodlight is a new type of electric light source based on the combination of two well-known principles of fluorescent lamp gas discharge and high-frequency electromagnetic induction. Because it does not have the filament or electrode necessary for conventional electric light sources, it is also called electrodeless lamp; usually the working frequency of low-pressure gas discharge high-frequency electrodeless lamp is 2.5~3.0MHz, that is to say, the operating frequency of floodlight is higher than that of ordinary The operating frequency (50Hz) of incandescent lamps and daily-used inductive fluorescent lamps, metal halide lamps, high-pressure sodium lamps and other lamps is 50,000-60,000 times higher than that of ordinary energy-saving lamps or electronic ballasts (30-60KHz). ) about 250 times higher.

With the continuous development of LED technology, new light sources are increasingly used in automobiles, and LED lights are an indispensable part. In the automotive industry, LEDs are widely used, but not all models are suitable for LED headlights; in some cases, auxiliary lighting systems (Side Lanes) are required to replace LED headlights. Structure LED Car Lights are composed of LED light-emitting diodes, which use the principle of electrothermal to control the power-on and power-off states of the light-emitting diodes by controlling the size of the current in the semiconductor, so as to realize the control of the working state of the light-emitting source. During the entire working process of the LED light source, several discrete drive units are generally connected in series to control the magnitude and direction of the current. Working principle LED Car lights are mainly composed of lamp holders, lampshades, light guide plates (also called diffuser plates) and so on. The working principle is: convert electrical energy into light energy, irradiate the front or rear of the vehicle through the light guiding effect of the diffusion plate, and then consume the light energy in the form of heat energy. When there is a certain distance between the LED lamp head and the light guide sheet of the diffusion plate, an illumination light source will be formed. LED Car lights have a long service life of 30,000 hours, while traditional light bulbs only last about 1,000 hours; while the vehicle is running, LEDs can self-adjust according to the intensity and brightness of the external light to achieve the best luminous effect. Working characteristics: Small power and high energy density. With high luminous brightness, it can be used in the auxiliary lighting system of automobiles to replace halogen lamps. Long service life (more than 5 years). It can conveniently realize the control and switching of far and low beams, that is, the intensity of the car lights can be changed by adjusting the color of the lights. It can realize more functions without adding any electronic components. Benefits of using LED Car Lights Using LED Car Lightscan reduce energy consumption, because LED is DC, it does not need high voltage power supply LED Car lights are very common in cars, and it does not require complex circuits to control the brightness of the lights Compared with xenon lamps and halogen headlights, LED headlights are more energy-efficient and have a longer service life, while xenon lamps and halogen headlights usually produce a certain degree of glare effect With the continuous advancement of LED technology, more and more LED vehicles will be used in the automotive industry (especially for high-end models). As consumers, we also hope that our cars have the characteristics of high quality, high safety performance, high light efficiency, long life and high environmental protection performance.
