Ultraviolet rays are a high -energy light wave with high energy, the naked eye cannot be recognized. Its wavelength is less than 400nm, which exists outside the outer side of the visible spectrum ultraviolet end, so it is called ultraviolet rays. By wavelength range divided into UV-A (320nm 400nm), UV-B (275nm 3 2 0 n m), UV-C (2 0 nm 2 7 5 nm), UV-D (100nm 200nm) four This band, wherein A, B, and C, three bands are also called disinfected ultraviolet rays. The three bands of A, B, and C have a certain disinfection effect, especially for the best disinfection effect with the C band. Light quantum theory believes that light is a special form of material movement. Each wavelength of 253.7nm UV photon has 4.9EV energy. The disinfection and sterilization of the UV line to water is mainly the maximum absorption wavelength (254nm) of nucleic acid (DNA). DNA can absorb high -energy ultraviolet radiation, cause adjacent alkali -based dislocation, and form pyrimidinedimer; Nucleic acid copy and protein expression leads to apoptosis. At present, research is limited to the research of the traditional ultraviolet-rays, and UV-LED as a new type of disinfection process may be more or less different from the traditional disinfection mechanism. Therefore. For more information, welcome to the official website http:///show-23-155.html

Many LED lighting masters, they pay great attention to LED lamp bead lighting computing. In their LED lamp bead lighting schemes, there will be a considerable part of the simulation calculation of LED lighting design. Moreover, the more complicated the space, the more you need to perform lighting calculations. As a quantitative design method, the illumination calculation is indispensable on most occasions. If there are some errors, it is not difficult to find the necessary illuminance through the LED lamp bead lighting design. Today we will introduce two methods. 1. The LED optical flux method LED lamp beads The optical flux method is mainly used in the equivalence of the LED lighting lamp space, and the calculation average illuminance is used. In addition to the use of open space such as office and factories, in restaurants, restaurants, houses, etc. need to improve In the space of the atmosphere, in order to confirm the approximate degree, it is convenient to use this LED illuminance calculation method. 2. The LED one -point calculation of the calculation of the calculation of the calculation algorithm is used when calculating the actual degree required for local lighting and the key display section. When the LED lamp beads are calculated for the calculation of the light flux method of LED lamp beads, 1 When installing a 100W nude bulb of 500lm, it is assumed that 30 % of the light beam should be directly illuminated on the ground. So how much is the direct illumination on the ground? E = f / a = 1500 * 0.3 / 10 = 45LX Except for the beams that are illuminated on the ground, other beams illuminate the ceiling and wall surface. If the reflectance of the ceiling and the wall is high, the reflection light will be added to the direct illumination of the ground, so the actual illumination is above 45LX or more. Most of the lamps for the basic LED lighting are direct light -equipped down light lighting and mixed lighting lamps of fluorescence lamps, as well as indirect lighting of ceiling tanks such as light glow slots. The illumination calculation of direct light matching, the more the light is affected by the ceiling and wall reflectance. Even if the setting of the room's reflectance is somewhat different, the average illuminance error will be. However, if there are high partition walls and furniture, the calculation results of the shadow part of the shadow deviate from. In addition, the indirect LED lighting of the ceiling must not only be affected by the ceiling surface, but also greatly affected the wall reflectance rate. The distance from the ceiling is different, and the lighting utilization rate will change, so it is difficult to calculate without error. Example: A room with 8m front room, 10m depth, and a net height of 2.4m. In order to make the indoor lighting uniform, 20 pookers lighting A light folds are neatly arranged, and the average on the ground is calculated at this time Photo? (The reflectance of the room is the ceiling: 70 %, the wall: 50 %, the ground: 20 %), the room space index = the opening room * depth / (opening room in -depth) * The height of the light source = 10 * 8 / (10 8) 2. 4 = 1.85, if the room spatial index is roughly taken between 1.5 and 2.0, where the reflectance of the room intersects, the lighting utilization rate is about 0.6. Maintenance rate M, incandescent lamps are 0.7 to 0.9, fluorescent lamps are 0.65 to 0.75, here is 0.8. E = f * n * u * m / a = 1520 * 20 * 0.6 * 0.8 = 180lx Average multiplied by the light of the lamps within the value of H (high light source), which means on the ground or work surface Will not produce uneven light spots. Calculate the illumination of a specific point. Since the local lighting of hanging decoration and lighting lights is used, when calculating the direct horizontal plane strength or vertical surface illumination of a specific point, the illumination can be used to use the point -by -point calculation algorithm one by one.

According to the current research, the competition in the LED light source market is becoming more and more intense, and car lighting is known as the new blue ocean in the LED light source market. Relative to the car lighting, it can stand out in the field of use of LED lamp beads, and suffers from the market scope and higher product added value than the year -old market. From the perspective of automotive lighting, the sun and crescents of the automotive industry's skills are growing, and the purpose of the growth of its growth is becoming more and more intellectual and green and environmentally friendly. Automotive lighting is transforming from the traditional field of lighting to the emerging LED light source category. According to industry research and explanation, it only takes a long period of time for LED lighting for vehicle LEDs and has entered the high supply chain door. Among them, the compound annual development rate of the output value of the out -of -the -art lamp and the far and near lights is higher to 21%and 48%. After integrating LED lamp beads, after the nation of the world has announced the disabled and banned incandescent lamp law, LED lighting car lights and main lighting needs climb. At the same time, with the improvement of people's approachable degree, people's requirements for the overall function of the car are promoting, and domestic brand cars will only be able to get better results with low configuration and low price competition. Domestic brand cars will also choose to improve the competition of car supporting facilities, and use the proportion of LED light source car lights to the rapid promotion. As far as the skills are concerned, LED light sources are a very ambitious light source. However, the LED light source needs to completely replace the traditional lamps. At present, the important concentration of the LED light source Lights is focused on a few high -end models, while the low -end vehicle accepts the LED light source car lights. At present, only high brake lights and side turn lights use LED light sources to use LED light sources. Because of the high cost, skills, and factors in various aspects, LED light sources are still not mature as the front lights of the car, and at least in the next three or five years, it will not be able to replace the halogen lamps and pyrine lamps in the next three or five years. However, the cost of integrated LED light sources in the future will continue to land and promote the simultaneous promotion of skills. In the automotive field, it will be widely used. The skills of the upperlight lead the growth of car lighting. --- The article comes from LED lamp beads, please indicate tianhui (China) www.tongjialed.com
