Embodiment 1

[0053] see Figure 1-17 , the present invention provides the following technical solutions: a detachable dimming high-efficiency anti-glare LED lamp, including a heat dissipation shell 3, a connection seat 1 is connected to the bottom of the heat dissipation shell 3, and a drive board 2 is arranged inside the connection seat 1. The inside of the heat dissipation shell 3 is provided with a light source board 4, the light source board 4 is provided with an LED lamp bead 5, a lens 6 is provided above the inside of the heat dissipation case 3, a honeycomb cover 7 is provided above the lens 6, and a honeycomb cover 7 is provided above the honeycomb cover 7. As for the optical component, a connection cover 8 is engaged on the top of the heat dissipation housing 3 , and a light outlet 81 is provided on the connection cover 8 .

[0054] Further, four card slots 31 are provided on the circumference above the heat dissipation housing 3 , and buckles 82 corresponding to the card slots 31 a...

Embodiment 2

[0063] The difference between this embodiment and Embodiment 1 is that further, the polarizers 11 are provided with dense and inclined polarizing teeth, and the polarizing teeth on the two superimposed polarizers 11 are arranged in the same direction and perpendicular to each other. or vice versa.

[0064] By adopting the above-mentioned technical solution, the polarizer 11 adopts a double-layer stacking mode, and utilizes the wedge angle superposition principle, and the polarizer 11 is designed to have a fixed angle a°, and two layers of polarizers 11 with the light-emitting surface facing up are placed in the connecting cover 8, close to The polarizer 11 of the lens 6 is fixed, and the upper polarizer 11 rotates around the Z axis on the X-Y plane. When the polarizer teeth of the two polarizers 11 are in the same direction, the entire light spot shift angle is 2a°; when the two polarizers When the direction of the polarizing teeth of 11 is at an angle of 90°, the offset angle...

Embodiment 3

[0066] The difference between this embodiment and Embodiment 1 is that the LED lamp bead 5 adopts KGF fluoride red powder technology, and the excitation efficiency of fluoride powder is much higher than that of conventional nitride powder in the red light band, that is to say, the same brightness Under normal conditions, fluoride powder lamp beads will have a higher display index than conventional nitride powder lamp beads. The luminous effect of R90 is basically the same as that of conventional nitride powder R80 by deploying fluoride phosphor powder in a certain proportion. Conventional high-resolution lamp beads on the market The schemes all use nitride powder, and the luminous efficacy of the phosphor powder scheme R90 is about 15% lower than that of R80. The KGF powder scheme can effectively make up for this defect and effectively improve the overall lighting efficiency; LED lamp bead 5 Use the Model 7070 from the lumen manufacturer.

Abstract

Disclosed is a detachable light-changing high-luminous-efficiency anti-dazzle LED lamp. The anti-dazzle LED lamp comprises a heat dissipation shell, a connecting base is connected to the lower portionof the heat dissipation shell, a driving plate is arranged in the connecting base, a light source plate is arranged in the heat dissipation shell, LED lamp beads are arranged on the light source plate, a lens is arranged on the upper portion in the heat dissipation shell, a honeycomb cover is arranged on the upper portion of the lens, an optical part is arranged above the honeycomb cover, and a connecting cover is clamped above the heat dissipation shell. The invention further discloses an implementation method of a detachable light-changing high-luminous-efficiency anti-dazzle LED lamp. Theconnecting cover and the heat dissipation shell are connected in a clamped mode through buckles and clamping grooves, the connecting cover is convenient to disassemble, and therefore an optical pieceis convenient to replace, the light angle is conveniently amplified, and light spots are discolored or deviated.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to a detachable dimming high-efficiency anti-glare LED lamp and a realization method thereof. Background technique [0002] At present, there are many anti-glare LED products on the market. The anti-glare is not removable, and at the same time, it is too single, does not solve the LED spot, the angle design is relatively large, and the optical efficiency is low. It is necessary to develop an LED lamp with a detachable structure, anti-glare, better spot effect, and high overall lighting efficiency. The structure is simple, easy to assemble and disassemble, and the one-time mold cost is invested. According to different application occasions and requirements, the honeycomb cover, prism or filter sheet is designed to be detachable. Consumers can choose the honeycomb cover, prism or filter sheet according to their needs. It is easy to install and has a wide range of applic...
