LED fluorescent light anti-glare and spot solution

With the strengthening of people's awareness of energy conservation and the maturity of LED lighting technology, the LED lighting market has taken initial shape, and this market will become larger and larger. At present, there are many manufacturers of LED fluorescent lamps on the market. I believe that everyone has to face a tough problem: the glare and flare of LEDs and the problem of strong directionality of light.

For LED dazzling problems, various manufacturers have adopted a variety of methods, such as the use of brushed PC masks, the use of frosted masks, the use of special phosphor materials, etc., but these methods are not ideal, the brushed mask can Eliminate glare, but the spot phenomenon is more serious. People spend a little longer under this kind of lamp. The eyes are prone to fatigue. If the eyes are used under such a lamp for a long time, it will cause the eyes to astigmatize. The frosted and milky white mask will reduce the light loss. Too big, the effect is too bad.

LED lighting is a bright future market. It is recommended that engineers should pay more attention to the lighting comfort of LED lamps when focusing on the efficiency, luminous flux and service life of LED lamps. Convinced that technology can solve comfort comfortably and will help you to better occupy the market.

With the optical film described above, the eye visually perceives that each LED is brighter but less glaring, and the diaphragm makes the LED daylight line more uniform and the viewing angle is significantly wider. The working principle of the diaphragm is to make the LED point light source that is irradiated onto the diaphragm into a uniform output of the surface light source, so that the problem of glare, light spot and widening the illumination range can be solved at the same time. In addition, the diaphragm transmits light. The rate is above 90, and the influence of the contrast is limited.

In general, the use of optical films has the following advantages:

1. Eliminate the unique spot of the LED. Since the LED fluorescent lamp is arranged in two rows or three rows, there will be a gap between the light emitted by each point source, so that a spot will be generated within a certain distance; after the optical film is used, the optical film is used. The incident point source light is evenly diffused and turned into a divergent light source, so that the light becomes very uniform and completely solves the spot problem.

2. Widening the illumination angle. LED illumination direction is very strong, the illumination angle is about 120 degrees, it is easy to produce illumination blind zone; after using optical film, due to the unique diffusivity of optical film, the illumination range can be extended to 180 degrees. Left and right, this can effectively eliminate the blind spot of illumination.

The direct benefit of the use of optical diaphragms for LED fluorescent lamps is that, with the same amount of LED fluorescent lighting, in the same area of space, the LED fluorescent lamps with diaphragms have no illumination blind spots, the light is uniform, and the lighting effects far exceed the ordinary LEDs. fluorescent lamp. And the greater the required illumination area, the more obvious this advantage.
