Embodiment 1
[0040] Such as figure 2 In the first prism layer 51, the bottom is a transparent substrate 511, and the thickness is 10 μm-100 μm.
[0041] There are N prism blocks 512 arranged horizontally and vertically on the substrate. The prism block 512 forms a frustum structure from its bottom. The adhesive layer between the prism blocks and the substrate is an ultraviolet irradiated sealing layer.
[0042] The bottom of each prism block 512 is a closely fitted rectangle of the same size, the length of the rectangle in the x-axis direction is between 20 μm and 1 mm, preferably 20 μm, 40 μm, 60 μm, 80 μm, and 100 μm, and the width of the y-axis is between 10 μm and 1 mm. Between, preferably 1-μm, 20 μm, 30 μm, 40 μm, 50 μm; the average height of the z-axis is between 10 μm and 1 mm, and each prism block 512 has four slopes and a top surface, forming a frustum structure with a gradually shrinking area , each prism block 512 includes an upper top surface 5121, a front side 5124, a rear ...
Embodiment 2
[0049] Such as Figure 6 Figure 7 In the second prism layer 52, the bottom is a transparent bottom plate 521, and the thickness is 50 μm-200 μm.
[0050] Prisms are attached to the bottom plate, mainly including a first prism 512 and a second prism 513, and the adhesive layer between the prism and the bottom plate is an ultravioletirradiation type sealing layer.
[0051] The first prisms are parallel to the longitudinal central axes of the second prisms, and are arranged in an array on the substrate, and a second prism 523 is arranged between the closest two first prisms 522 . The two adjacent first prisms 522 and second prisms 523 compensate each other.
[0053] Such as Figure 7 As shown, the first prism includes a second upper top surface 5221, a lower bottom surface 5223 and an inclined surface 5222. The cross section of the prism is an isosce...

Abstract
The invention provides an anti-glare illumination box. The anti-glare illumination box comprises a shell; an LED lamp, a fixing plate, a light filter plate and a prism component are arranged inside the shell; the fixing plate is arranged at the front side of the LED lamp and is provided with a light emitting hole which is used for the light of the corresponding LED lamp to be emitted; the light filter plate is rotationally fixed to the front side of the fixing plate; the prism component is fixed to the front end of the light filter plate; and the prism component comprises a first prism layer and a second prism layer which is arranged at the rear side of the first prism layer. According to the anti-glare illumination box provided by the invention, the light filter plate can be randomly adjusted to change the light color or wave band; and by arranging the prism component, the probability of light scattering is reduced, the light condensation effect is enhanced, and glare quantity is reduced, so the eyes of a person can be kept in a comfortable state.
Description
technical field [0001] The invention relates to the field of lighting equipment, in particular to an anti-glare lighting box. Background technique [0002] When using optical equipment, such as lamps, it may cause discomfort to human eyes due to being too dim or dazzling. The main reason for this problem is not the light source, but the poor effect of the refraction plate on the outside of the light source for concentrating or refracting light. [0003] "Glare" is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or the brightness difference between the background and the center of the field of view is large, "glare" will occur. Dazzle refers to the visual condition that causes visual discomfort and reduces the visibility of objects due to unsuitable brightness distribution or extreme brightness contrast in space or time in the field of vision. In the field of vision, there is a light sensation that the human eye cannot adapt to, ...
