What is a floodlight? Floodlight is a point light source that can illuminate evenly in all directions. Its irradiation range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene.

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.

What is an Ultra Violet Light？UltraViolet light, also known as a UV Light, is a light source used for disinfection and sterilization,ultraviolet light with a wavelength of 200~410 nm

Plant growth light is a light source used to grow plants. It is mainly used for planting and management of crops and flowers. It can generally be divided into three types: red light, blue light and green light. Red light is the red light spectrum in the visible spectrum, which is suitable for photosynthesis and can promote the chlorophyll of plants; blue light is a kind of monochromatic light, which can produce a large amount of anthocyanins; green light is a special Spectrum, usually yellow and green. The plant growth light can increase the chlorophyll content of the plant and promote the photosynthesis of the plant in a certain concentration of nutrient solution. It can promote the enlargement of leaf cells; make the leaves shiny, brightly colored, and thick stems; make crops grow robustly, reduce diseases and insect pests, etc. It is mainly used in the planting management of vegetables, flowers, etc., which is very helpful for increasing production. What is light? The speed of light is the speed of light. The amount of light passing through a unit area in a unit time is called the speed of light. Light has three important characteristics: directionality, a long-term change rule, energy dissipation. On Earth, everything has a certain size and shape, a certain wavelength and different brightness, and they transform into each other in space. The energy of different lights is related to the wavelength: light of one color (red light) contains the most energy; followed by blue, red and blue light, among which red light contains the least energy; white, blue and yellow light contains the least energy. What are the functions of a plant growth light? By improving photosynthesis, increasing photosynthetic products, improving plant stress resistance, and promoting yield increase. By improving the absorption of nutrients, promote root development, enhance plant resistance, and reduce diseases. By adjusting the stomatal opening of the leaf and the change of the leaf structure (that is, changing the stomatal opening; increasing the thickness of the leaf) to achieve the purpose of light regulation; Regulate photosynthesis by adjusting the sensitivity of plants to light intensity. Common types In general, plant growth lights are mainly divided into three categories: Yellow light: mainly used for the production of vegetables and other plants, which can increase the light and promote growth during the vegetative reproduction of plants; Purple light lamp: that is, incandescent bulb, which can be used for indoor greening and flower cultivation management; Strobe light: it is a new light source that has only appeared in recent years. Choose Choose according to the application needs: such as flower cultivation, seedling cultivation, etc. Select by function: mainly used for photosynthesis and other functions. How to use: According to different needs, choose different photoperiods and light colors to regulate the light of plants to achieve the desired effect.

LED Car lights refer to devices that use the principle of electroluminescence to convert electrical energy into light energy. Compared with traditional lighting sources, LED lights have the advantages of low energy consumption, long life, and convenient use. 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.
