Problems solved by technology

In traditional lamps, high-pressure sodium lamps and reflectors are often used to meet the requirements of illuminance per unit area by using the characteristics of high-power and high-luminous flux of high-pressure sodium lamps. The installation of auxiliary equipment on the top makes the structure of the lamp more complex, increases the overall cost, and also increases the difficulty of installation and maintenance
[0003] In order to solve the problem of high power consumption, people have developed LED lamps. The principle is that the light emitted by the LED lamp beads is concentrated and enhanced by the convex lens and then projected to the ground. However, because the four sides of the convex lens also emit light, the LED lamp with this structure The irradiation distance is short, which cannot meet the needs of the above special places
For this reason, people replace the convex lens with a reflector, which includes an outer guard plate of the reflector and a reflective bowl. The reflective bowl is conical, and its inner wall is arc-shaped. After the secondary reflection is superimposed and enhanced, the illuminance reaching the ground meets the needs of the illuminance of the above-mentioned special places, and the power is also small, which saves power. dazzling need

Embodiment 1

[0028] The dimensions of the bottommost opening of the stepped pyramid are: L=32, W=32, X=8, α=20°, β=γ=38°.

[0029] The stepped pyramid type has 9 floors, with a total height of 16.5mm. The height H1 of the uppermost layer located on the bottom surface of the LED lamp bead mount is 1.8mm, the height until the eighth layer is 1.8mm, and H2 is 2.1mm.

Embodiment 2

[0031] The dimensions of the bottommost opening of the stepped pyramid are: L=25.6, W=25.6, X=8, α=20°, β=γ=29°.

[0032] The stepped pyramid type has 9 floors, with a total height of 16.5mm. The height H1 of the uppermost layer located on the bottom surface of the LED lamp bead mount is 1.8mm, the height until the eighth layer is 1.8mm, and H2 is 2.1mm.

Embodiment 3

[0034] The dimensions of the bottommost opening of the stepped pyramid are: L=32, W=25.6, X=8, α=20°, β=38, γ=29°.

[0035] The stepped pyramid type has 9 floors, with a total height of 16.5mm. The height H1 of the uppermost layer located on the bottom surface of the LED lamp bead mount is 1.8mm, the height until the eighth layer is 1.8mm, and H2 is 2.1mm.

[0036] In actual use, the reflector of Example 3 is compared with commonly used high-pressure sodium lamps and LED lamps with convex lenses, and the results are as follows:

Abstract

The invention relates to a rectangular light reflector of an efficient anti-glare LED (light emitting diode) lamp fitting, wherein the light reflector is internally provided with a step golden-tower-shaped light reflection surface; the uppermost layer of the step golden-tower-shaped light reflection layer is provided with an upper opening for mounting LED lamp beads, and the uppermost layer end surface is provided with a quadrate with one side of 8mm; the height of each layer of the step golden tower shape from the first layer to last but one layer are equal; an included angle between the slope surface in each layer of the step golden tower shape and the vertical plane is 20 degrees; the opening of the lowermost layer of the step golden tower shape is a light emergent opening which is rectangular; the length of one side of the rectangle is 25.6-32mm, and the length of the adjacent side is 25.6-32mm. The light reflector is especially suitable for the use in large physical training places or sports tournament places, the normal sports of the sportsman can not be influenced; the lamp fitting which is provided with the light reflector has uniform illumination, has no light spots, has a long service life, saves energy sources, and is suitable for the using in waiting halls, waiting rooms, chambers, stadiums and other special places.

Description

technical field [0001] The invention belongs to the field of lighting equipment, in particular to a high-efficiency anti-glare LED lighting rectangular reflector. Background technique [0002] Large-area lighting fixtures are a special kind of lighting fixtures, which are used in airports, clubs, sports venues and other special places with large areas, high installation positions, anti-glare and high requirements for ground luminous flux. In traditional lamps, high-pressure sodium lamps and reflectors are often used to meet the requirements of illuminance per unit area by using the characteristics of high-power and high-luminous flux of high-pressure sodium lamps. The installation of auxiliary equipment on the lamp makes the structure of the lamp more complicated, increases the overall cost, and also increases the difficulty of installation and maintenance. [0003] In order to solve the problem of high power consumption, people have developed LED lamps. The principle is th...
