Embodiment 1
[0017] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the present invention uses a light box 1 and an LED light bar 2. The light box 1 is composed of a front light-transmitting plate 3 and a surrounding frame 4. The LED light bar 2 is placed in the light box 1. According to the size of the light box 1, more light boxes can be placed in the light box 1. The LED light bar 2 can be arranged horizontally or vertically. The LED light bar 2 includes an LED light 5 and a substrate 6. The LED light 5 is fixed on the substrate 6, and the LED light 5 in the LED light bar 2 is connected in series. The driving circuit is connected to the power supply. The LED lamp 5 includes an LED lamp bead 7, a lens 8 and an LED lamp shade 9. The LED lamp bead 7 is welded on the substrate 6, the lens 8 is embedded in the LED lamp shade 9, and the LED lamp shade 9 is glued and fixed on the substrate 6. The shape of the lens 8 is basically a truncated cone shape. At the large round end of ...
Embodiment 2
[0023] According to the same structure of Example 1, the radius of the cylinder 10 of the lens 8: the height of the convex edge 11: the distance between the tops of the convex edge 11: the side length of the square hole 12: the hole depth of the square hole 12: the square hole 12 The height of the convex spherical surface 13 at the top: the ratio of the distance from the front end surface of the cylinder 10 to the small round end of the lens 8 is 100:3:20:40:60:35:90, and the height of the convex rib 11 is equal to that of the convex The radius of the edge 11 and the side length of the square hole 12 are equal to the diameter of the convex spherical surface at the top of the square hole 12, and the brightness of the LED lamp 5 is 14750 lux, and the uniformity is 76%.
Embodiment 3
[0025] According to the same structure of Example 1, the radius of the cylinder 10 of the lens 8: the height of the convex edge 11: the distance between the tops of the convex edge 11: the side length of the square hole 12: the hole depth of the square hole 12: the square hole 12 The height of the convex spherical surface 13 at the top: the ratio of the distance from the front end of the cylinder 10 to the small round end of the lens 8 is 100:2:20:30:40:30:100, and the height of the convex rib 11 is equal to that of the convex The radius of the edge 11 and the side length of the square hole 12 are equal to the diameter of the convex spherical surface at the top of the square hole 12, and the brightness of the LED lamp 5 is 12620 lux, and the uniformity is 74%.
