Background

In order to obtain a comfortable, high quality lighting environment, it is very necessary to suppress glare by improving the lamp. In recent years, indoor lighting in the european union has been given the standard of anti-glare, i.e., UGR <19, or even lower. In 1995, CIE (international commission on illumination) has proposed the concept of anti-glare for lamps, and ugr (unifiedglararating) was used as an index for evaluating discomfort glare in indoor lighting environments. With the development of the LED chip technology, the LED lamps become brighter and brighter, and discomfort glare becomes more and more serious.

In the prior art, a linear lamp (linear lamp) mainly comprises a lamp main body (shell), an LED lamp strip and a cover plate (diffusion plate), wherein the lamp main body is used for fixing the lamp main body, the LED lamp strip is a luminous source, the cover plate plays a role in diffusing the light source, the light is diffused as much as possible, the illumination range is enlarged, in order to prevent discomfort caused by strong light to human eyes, the cover plate can be subjected to anti-dazzle treatment in the prior art, usually, frosting treatment is carried out on the surface of the transparent cover plate, so that the light source is subjected to diffuse reflection through fine frosted particles, the anti-dazzle purpose is achieved, although the production process is simple, the cost is low, the service life of an anti-dazzle layer of the linear lamp is short, and partial light can be blocked, so that the illumination effect of the lamp is reduced.
