LED (light-emitting diode) down light

Abstract

The invention discloses an LED (light-emitting diode) down lamp which comprises an inverted-truncated-cone-shaped lamp housing, a surface ring, an LED light source structure, a drive unit box and a drive unit, wherein the surface ring is connected and fixed to the upper end of the lamp housing; the LED light source structure is fixedly arranged on the inner bottom surface of the surface ring and irradiates towards the inside of the lamp housing; the drive unit box is installed on the lower end of the lamp housing; the drive unit is arranged in the drive unit box and electrically connected with the LED light source structure; cambered convex surfaces are fully distributed on the internal surface of the lamp housing; the surface of each camber convex surface is coated with a reflective layer capable of reflecting light rays; the LED light source structure comprises an annular substrate fixedly arranged on the inner bottom surface of the surface ring, and a plurality of LED lamp beads which are distributed on the annular substrate and electrically connected with the drive unit; and the LED lamp beads irradiate towards the cambered convex surfaces of the lamp housing, and irradiate towards the outside only under the reflection action of the cambered convex surfaces.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an LED downlight. Background technique [0002] The LED light sources of existing LED downlights mostly use point light sources to emit light, and most of them are directed outwards. This design leads to uneven distribution of illumination light intensity, narrow light emitting range, small light emitting surface of LED light source, and excessive light intensity distribution. Concentration causes light spots on the ground, and it is easy to produce glare to make people feel dizzy. In addition, people can directly see the LED lamp beads inside the lamps, which is not beautiful enough. In order to alleviate the above situation, it is generally necessary to install a light-transmitting sheet, which can effectively block the LED lamp beads from being exposed, and can reduce the glare to a certain extent, but this method cannot fundamentally solve the above-mentioned problems .
