Embodiment 1

[0039] Such as figure 2 In the upper prism layer 1, the bottom is a transparent substrate 11 with a thickness of 10 μm-100 μm.

[0040] N prism blocks 12 in horizontal and vertical arrays are arranged on the substrate. The prism block 12 forms a frustum structure from its bottom. The adhesive layer between the prism block and the substrate is an ultraviolet irradiated sealing layer.

[0041] The bottom of each prism block 12 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 12 has four slopes and a top surface, forming a frustum structure with a gradually shrinking area , each prism block 12 includes a first upper top surface 121 , a first front side 124 , a firs...

Embodiment 2

[0048] Such as Figure 6 Figure 7 The bottom of the lower prism layer 2 is a transparent bottom plate 21 with a thickness of 50 μm-200 μm.

[0049] Prisms are glued on the bottom plate, mainly including a first prism 12 and a second prism 13, and the adhesive layer between the prism and the bottom plate is an ultraviolet irradiated sealing layer.

[0050] 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 23 is arranged between the closest two first prisms 22 . The two adjacent first prisms 22 and second prisms 23 compensate each other.

[0051] The material of the prism is optical glass, quartz glass, alkali metal halide (such as sodium bromide) crystal, etc.

[0052] Such as Figure 7 As shown, the first prism includes a second upper top surface 221 , a lower bottom surface 223 and a slope 222 , and the cross section of the prism is an isosceles trapezoid, including an up...

Abstract

The invention provides anti-dazzle illuminating equipment. The anti-dazzle illuminating equipment comprises a light source layer. A plurality of LED beads are arranged in the light source layer. A lower prism layer is arranged on the light source layer. An array prism strip structure is arranged on the upper surface of the lower prism layer. An upper prism layer is arranged on the upper portion of the lower prism layer. Prism blocks are arranged on the lower surface of the upper prism layer. The top projection of the axial line of each prism strip and the top projection of the longitudinal axis of the upper prism layer cross and form an acute angle alpha, and alpha is greater than or equal to 60 degrees but smaller than or equal to 90 degrees. The lower prism layer comprises a bottom plate and prism strips on the upper portion of the bottom plate. The prism strips comprise first prisms and second prisms. The first prisms and the second prisms are arranged in an alternative mode to form a pattern face. The lengths of the upper top edges of the isosceles trapezoids in the prism strips are fixed, the lengths of the lower bottom edges of the isosceles trapezoid in the prism strips are changed linearly, and every two adjacent lower bottom edges in the same section compensate each other. The light scattering probability is lowered, the condensation effect is improved, the dazzle amount is reduced, and human eyes are enabled to be in a comfortable state.

Description

technical field [0001] The invention relates to the lighting field, in particular to an anti-glare lighting device. 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, which may ...
