Embodiment 1

[0038] 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.

[0039] 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.

[0040] 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 si...

Abstract

The invention provides a lighting box which comprises a shell. An LED lamp, a fixing plate, a light filter plate and a prism assembly are arranged in the shell. The fixing plate is arranged on the front side of the LED lamp; and a bright dipping hole penetrating corresponding to light ray of the LED lamp is formed in the fixing plate; the light filter plate is rotatably fixed on the front side of the fixing plate; and the prism assembly is fixed at the front end of the light filter plate. The prism assembly comprises a first prism layer and a second prism layer on the back side of the first prism layer. According to the lighting box, filtering pieces can be adjusted at any time to change light ray colors or wave bands; through the configuration of the prism assembly, the probability of light ray scattering is reduced, the light condensation effect is strengthened, and glare quantity is reduced, so that human eyes are in a comfortable state.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a spotlight 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, wh...
