A reversible led downlight

Abstract

The invention discloses a turnover LED down lamp. The turnover LED down lamp comprises a base, a cover body, a lamp cup installed between the base and the cover body, and an LED lamp body installed inside the lamp cup, wherein the lamp cup is hemispherical, and a groove used for containing the LED lamp body is formed in the lower end of the lamp cup in a concaved mode. A light permeable hole is formed in the position, right facing the groove, of the base, the inner wall of the light permeable hole is shaped like a concaved arc which is matched with the outer wall of the lamp cup, the diameter of the outer edge of the light permeable hole is smaller than the diameter of the lamp cup, the lower end of the cover body is installed on the base, a containing cavity for containing the lamp cup is formed between the cover body and the base, a stopping portion used for limiting the lamp cup extends downwards from the top end of the inner wall of the cover body, and the lamp cup can be arranged inside the containing cavity in a flip mode. The lamp cup is designed to be hemispherical, so that the lamp cup is matched with the concaved arc inner wall of the base and the stopping portion of the cover body, and therefore the lighting angle can be adjusted within the range of 0-28 degrees according to needs, the lighting range of the LED down lamp is increased, and different requirements of users are met.

Description

technical field [0001] The invention relates to the technology in the field of illumination, in particular to a reversible LED downlight whose irradiation angle can be adjusted as required. Background technique [0002] In the current LED lighting industry, the use of LED downlights is becoming more and more common. LED downlight is a kind of lighting fixture embedded in the ceiling, and it is generally a directional lighting fixture. Only its opposite side can receive light. The beam angle belongs to spotlight. The object to be illuminated can easily set off a quiet environment atmosphere, but due to its fixed structure, a single downlight can only illuminate a fixed angle, which limits the scope of application of the LED downlight. In order to enable the LED downlight to adjust the irradiation angle according to the needs, the industry makes the LED downlight rotatable, but the rotation method of this type of LED downlight is to install the LED lamp cup in the fixed brack...

AI Technical Summary

Problems solved by technology

LED downlight is a kind of lighting fixture embedded in the ceiling, and it is generally a directional lighting fixture. Only its opposite side can receive light. The beam angle is concentrated, the light is concentrated, and the contrast between light and dark is strong. The object to be illuminated can easily set off a quiet environment atmosphere, but due to its fixed structure, a single downlight can only illuminate a fixed angle, which limits the scope of application of LED downlights

In order to enable the LED downlight to adjust the irradiation angle according to the needs, the industry makes the LED downlight rotatable, but the rotation method of this type of LED downlight is to install the LED lamp cup in the fixed bracket in a pivotal manner. Realize rotation within a certain angle range, but cause the whole structure to be complicated, and the volume of the whole LED downlight is relatively large, resulting in high installation cost, maintenance cost and manufacturing cost of the LED downlight. At the same time, the heat dissipation of this type of LED downlight The effect is poor, which reduces the lumen maintenance rate of the LED lamp and shortens the service life of the downlight
