Wall washing lamp of light guide plate

Abstract

The invention discloses a wall washing lamp of a light guide plate. The lamp comprises a frame body, wherein a power source is arranged in the frame body, a fixed frame is arranged on the back of the frame body, a breadboard connected with the power source is arranged on the lateral of the frame body, a plurality of LEDs (light emitting diode) are arranged on the breadboard, a light guide plate is arranged in the frame body adjacent to the LED, the back of the light guide plate is formed by a slop surface and the thickness of the two sides of the light guide plate is different, the thicker side is close to the LED module, the thinner side is far from LE, the front side of the light guide plate is adjacent to a transparent plate, the transparent plate is fixed on the front side of the frame body, the two sides of the frame body are arranged on plugs. The invention has the advantages of lower cost, less heat in work and uniform illumination, and no glare and the like.

Description

technical field [0001] The invention relates to a wall washer, in particular to a light guide plate wall washer. Background technique [0002] The wall washer can be used to project light onto the building to brighten the building. It is generally installed at the low or top of the building to illuminate the building upwards or downwards. The existing wall washer The structure of the lamp will use multiple high-power LED lamp beads and lenses in the frame to achieve the purpose of washing the wall. The LED lamp beads emit light and directly shine through the lens. This method has several disadvantages : 1. Due to the use of multiple high-power LED lamp beads, and the unit price of high-power LED lamp beads is relatively expensive, and the heat accumulates during work, the lamp frame must use more aluminum materials to dissipate heat, and the power supply also requires Higher and compatible with high-power LED lamp beads, resulting in higher prices, and more power consumptio...

[0002] The wall washer can be used to project light onto the building to brighten the building. It is generally installed at the low or top of the building to illuminate the building upwards or downwards. The existing wall washer The structure of the lamp will use multiple high-power LED lamp beads and lenses in the frame to achieve the purpose of washing the wall. The LED lamp beads emit light and directly shine through the lens. This method has several disadvantages : 1. Due to the use of multiple high-power LED lamp beads, and the unit price of high-power LED lamp beads is relatively expensive, and the heat accumulates during work, the lamp frame must use more aluminum materials to dissipate heat, and the power supply also requires Higher and compatible with high-power LED lamp beads, resulting in higher prices, and more power consumption during use, it can be seen that the overall cost of the lamp is relatively high; 2. The current structure of the wall washer needs to be equipped with One lens is used to achieve the optimal brightness, but this will lead to different light effects emitted by each LED lamp bead, and finally the light reaching the wall is also inconsistent in brightness, and the position is uneven, and the glare phenomenon is serious, resulting in poor wall washing effect
