How to solve the dazzling and flare problems of LED fluorescent lamps
With the maturity of LED lighting technology, the LED lighting market has initially taken shape, and this market will become larger and larger. At present, there are many manufacturers of LED fluorescent lamps on the market. I believe everyone will have to face a thorny problem: the dazzling and flare of LEDs and The problem of strong light directionality.
For the problem of LED dazzling, various manufacturers have adopted various methods, including brushed PC masks, frosted masks, special phosphor materials, etc., but these methods are not ideal, and brushed masks can be used. Elimination of glare, but the phenomenon of light spots is more serious. People who spend a long time under this kind of lamp are prone to eye fatigue. If they are used under this kind of lamp for a long time, they will also cause eye astigmatism; while using matte and milky white masks to lose light Too big, the effect is too bad.
LED lighting is a promising market. When this market was just formed, engineers paid attention to the efficiency, luminous flux and service life of LED lamps, and took a little time to consider the comfort of LED lamps. I am technically comfortable. Sex will help you better occupy the market.
After using the above optical diaphragm, the visual observation of each LED feels that each LED is brighter but not dazzling. The diaphragm makes the LED fluorescent light more uniform, and the viewing angle is significantly wider. The working principle of this diaphragm is to illuminate the hash The LED point light source to the diaphragm becomes a surface light source with uniform output, so that the problems of glare, spot and widening of the irradiation range can be solved at the same time. In addition, the light transmittance of the diaphragm is above 90, and the illuminance is limited.
In general, the LED fluorescent lamp solution has the following advantages after using the optical film:
1. Eliminate the unique light spot of LED. Since the LED fluorescent lamp is arranged in two or three rows regularly, there will be a gap between the light emitted by each point light source, so that the light spot will be generated within a certain distance; after using the optical diaphragm, the optical diaphragm Evenly diffuse the incident point light source light and turn it into a divergent light source, so that the light becomes very uniform and completely solve the problem of light spots
2. Broaden the illumination angle. The direction of LED light emission is very strong, the illumination angle is about 120 degrees, and it is easy to produce blind spots; after the optical film is used, due to the unique diffusibility of the optical film, the light irradiation range can be extended to 180 degrees Left and right, this can effectively eliminate the blind spot of lighting.
The direct benefit of the use of optical diaphragms in LED fluorescent lamps is that the same number of LED fluorescent lamps are used for lighting. In the same area of space, the LED fluorescent lamps using diaphragms have no blind spots and uniform light, and the lighting effect is much better than ordinary LEDs. Fluorescent lamps. And the larger the lighting area required, the more obvious this advantage.
