Infrared LEDs play an important role in applications, from remote controls to security systems, without these components. However, how to judge the quality of infrared LEDs during use? What are the reception methods for infrared LEDs? This article will introduce this. How to judge the quality of infrared LEDs Appearance inspection: First, check the appearance of the diode for obvious defects, such as defects, cracks, etc. Electrical parameter inspection: By calculating and measuring the equivalent values of resistance, current, and voltage, check whether the electrical parameters of the component strictly comply with the specified values. Optical parameter inspection: Detect whether the infrared emitted from the infrared receiver is normal, and test whether its output power meets the requirements. Other tests: Special testing instruments can be used to test parameters such as infrared wavelength and emission angle. Receiving method of infrared LEDs There are two main reception methods for infrared LEDs Direct reception: Install the infrared LEDdirectly on the module or device that needs to be detected or received, such as an infrared signal receiver. Indirect reception: The emitted infrared signal is transmitted to a designated location through phenomena such as reflection, refraction, and scattering, and is received and processed by an infrared receiver. A common example is an infrared remote control. It should be noted that regardless of the receiving method, it is necessary to ensure stable light quality of the infrared LED, and to correctly calculate the emission angle and wavelength of the infrared to ensure its performance and effectiveness. Infrared LEDs, as an important electronic component, have a wide range of applications in modern society, but how to judge their quality is very important for users.

With the rapid development of modern electronic technology, SMD LEDs are a mainstream component used for display and lighting in the current electronic field. They are small in size, low in power consumption, uniform in emission, and have a wide range of applications. They can be used in electronic products, lighting products, traffic signal lights, car lights, and other fields. Next, let’s delve deeper into SMD LEDs. The Basic Principles of SMD LEDs The basic structure of SMD is a substrate sandwiched between a p-type semiconductor and an n-type semiconductor. By applying voltage to these two semiconductors, electron hole pairs can be formed within the inclusion layer to emit light. SMD LEDs have high luminous efficiency, and in fact, they have become one of the mainstream products in LED lighting applications. Application characteristics of SMD LEDs Small size: SMD LEDsare small in size and light in weight, generally 20% to 30% smaller than conventional LED lights, making them easy to carry and install. Low power consumption: SMD LEDsnot only have small size, but also have low power consumption, greatly saving electricity and bills. Sharp and Vulnerable: The surface of the SMD is encapsulated in plastic, which has a short service life and durability. Therefore, pay attention to the usage environment and conditions to avoid causing losses. Uniform luminescence: The light output angle of the SMD LED point light source is relatively small, and the radiation direction is relatively concentrated, so the lighting effect will be better when the light is more concentrated. In summary, SMD LEDs are widely used in the electronic field. Their compact size, significant energy-saving effects, and long service life make them an indispensable part of modern electronic technology. But at the same time, we also need to pay attention to protecting the environment, regulating costs, and optimizing design, so that SMD LEDs can play a greater role in the application process.

Optical imaging is the process of converting optical information on an object into an image through an optical system. An optical system is composed of multiple optical devices, such as lenses, prisms, reflectors, etc., the most basic of which is a lens. The imaging principle of LED Optical Systems is based on the basic laws of light propagation, refraction, and reflection, and the imaging of objects is achieved through the combination of lenses and optical devices. The imaging principle of LED Optical Systems can be divided into two situations: convex lens imaging principle and concave lens imaging principle. The principle of concave convex lens imaging The principle of convex lens imaging mainly involves the direction of the image. When the object is located on the left side of the lens focus, the image formed by the refraction of light through the lens is located on the right side of the lens; When the object is located on the right side of the lens focus, the image formed by the refraction of light through the lens is located on the left side of the lens. If the object is located at the focal point of the lens, the light rays after imaging will be parallel and there will be no deviation in the light path. The principle of concave lens imaging is also similar. However, due to the spherical aberration of concave lenses, they are rarely used in practical applications. Propagation of light path The basis of imaging principle is the propagation of incident light along a traceable optical path. The factors that affect the optical path in LED Optical Systems include the refractive index of imaging optical devices, the possible scattering of light when passing through optical devices, and so on. We can predict the propagation and imaging of light in optical devices through classical geometrical optics or radiation metrology. The imaging principle of LED Optical Systems is based on the basic laws of light propagation, refraction, and reflection, and the combination of optical devices such as lenses is used to achieve the imaging of objects. Understanding and mastering the imaging principles of LED Optical Systems is of great significance for the design and application of LED Optical Systems.

The application of ultraviolet technology in the field of disinfection has gradually become popular. With its advantages of high efficiency and reliability, ultraviolet disinfection lamps are widely used in fields such as homes, healthcare, food, cosmetics, and water treatment. However, the efficacy of ultraviolet lamps is not determined by the duration of use, but rather by calculations and arrangements based on different fields. Medical industry The medical industry is one of the important application fields for ultraviolet lamp disinfection. Medical equipment, operating rooms, air, surfaces, etc. all require ultraviolet disinfection. The disinfection time varies depending on the size and classification of the equipment. Usually, using 254nm ultraviolet disinfection lamps for relatively small medical devices takes only 10-20 minutes to complete, while large equipment and operating rooms require the use of multiple tubes or lamps in combination. Depending on the size, layout, and supplementary air circulation conditions of different equipment, it generally takes 30 minutes to 2 hours. Food industry In the food processing industry, the requirements for environmental hygiene are very high, and the disinfection requirements for bacteria and viruses are also very strict. The disinfection of ultraviolet lamps in food processing environments requires attention to different types of food and the level of cleanliness. In general, the UV Lights on the surface of the food processing area needs to be used for at least 30 minutes, and the UV Lights on the ceiling needs to be used for 60 minutes, with an ambient temperature not exceeding 50 ° C. In summary, the disinfection time of ultraviolet lamps varies in different fields and needs to be determined based on specific circumstances. The disinfection time is not as long as possible, but should be calculated comprehensively based on multiple factors such as equipment size, power, number of light tubes, program used, environment, and working state. When using ultraviolet lamps for disinfection, it is also necessary to pay attention to safety measures, safety distance and time, to prevent damage to the human body or equipment.
