Problems solved by technology

The shape of the anti-glare board is a triangular prism, that is, a triangular pyramid. Some light with a large angle will have a large UGR value when refracted and reflected by the anti-glare layer, which cannot effectively reduce the UGR value of the light with a large angle.

Embodiment 1

[0022] combine Figure 1 to Figure 3 , to describe this embodiment in detail. An anti-glare plate with a light-absorbing layer involved in this embodiment includes a light-transmitting layer and a first UGR reducing layer and a first absorbing layer located on one side of the light-transmitting layer; the first UGR reducing layer and the first absorbing layer Alternate settings. The first UGR lowering layer consists of triangular edges arranged in parallel. The first absorbent layer consists of partitions arranged in parallel. The triangular ribs in the first UGR reducing layer are arranged in parallel with the partitions in the first absorbing layer. The cross section of the triangular rib is triangular, and the cross section of the partition is rectangular. In this embodiment, the cross section of the triangular ridge is a regular angle. In this embodiment, the triangular edge and the partition have a common side.

Embodiment 2

[0030] combine Figure 4 to Figure 6 , to describe this embodiment in detail. The difference between the anti-glare plate with the light absorbing layer in this embodiment and the first embodiment is that the length of the triangular edge is in the range of 0.5-2 mm, which is 2 mm in this embodiment. The thickness of the light-transmitting layer can be selected in the range of 0.5-2mm, and 1mm is selected in this embodiment.

[0031] In the present invention, one A° is selected, and the half of the height of the separator and the height of the triangular edge can be calculated by substituting it, which is 1mm. The width of the separator in this embodiment is 0.4 mm.

Abstract

The invention discloses an anti-glare plate with light absorbing layers. The anti-glare plate with the light absorbing layers is characterized in that the anti-glare plate with the light absorbing layers comprises a light transmission layer, a first UGR (unified glare rating) reduction layer and a first absorbing layer, wherein the first UGR reduction layer and the first absorbing layer are positioned at one side of the light transmission layer and are arranged at intervals; and a second UGR reduction layer and a second absorbing layer are positioned at the other side of the light transmissionlayer and are arranged at intervals. According to the anti-glare plate with the light absorbing layers, the UGR reduction layers and baffle plates are arranged at the two sides of a light transmission plate and serve as the light absorbing layers; and the UGR can be reduced by using the reflection of the baffle plates or absorbing large-angle light.

Description

technical field [0001] The invention relates to the technical field of anti-glare in LED lighting devices, in particular to an anti-glare plate with a light absorbing layer. Background technique [0002] In a conventional LED lighting device, a layer of anti-glare board is provided to obtain a uniform and soft display effect. An anti-glare layer is usually arranged on the anti-glare plate, and the function of the anti-glare layer is to reduce the UGR value of light passing through the layer. The shape of the anti-glare board is a triangular prism, that is, a triangular pyramid. Some light with a large angle has a large UGR value when refracted and reflected by the anti-glare layer, which cannot effectively reduce the UGR value of the light with a large angle. Contents of the invention [0003] The object of the present invention is to provide an anti-glare plate with a light absorbing layer, which can effectively reduce the UGR value of light at large angles when using tr...
