LED wall washer

Abstract

The invention discloses an LED wall washer, which comprises a heat dissipating lamp housing, a plurality of LED light sources arranged in the heat dissipating lamp housing, a driving device arranged in the heat dissipating lamp housing, a light-guide transmitting cover mounted on the heat dissipating lamp housing, an end cover fixed to the end face of the heat dissipating lamp housing, and a mounting frame mounted at the bottom of the heat dissipating lamp housing. A partition plate is arranged in the middle in the heat dissipating lamp housing, the upper end of the partition plate is provided with a light source concave cavity, and the lower end of the partition plate is provided with a hidden chamber; the LED light sources are tightly attached to the upper end face of the light source concave cavity, and meanwhile the driving device is tightly attached to the bottom of the hidden chamber so as to be isolated from the LED light sources to avoid heat disturbance; the heat dissipating lamp housing is of an integrally formed structure and is made of heat-conducting metal; and each LED light source is independently covered with a cylindrical independent lens holder playing a refraction role, the independent lens holders are covered with independent reflecting covers playing a reflective role, the independent reflecting covers are each in an inverted circular truncated cone shape, and the surfaces of the independent reflecting covers are coated with reflective coatings.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an LED wall washer. Background technique [0002] Wall washer, as the name suggests, is to let the light wash the wall like water, mainly used for architectural decorative lighting, and to outline the outline of large buildings. Because LED has the characteristics of energy saving, high luminous efficiency, rich colors, and long life, the current wall washer of other light sources is gradually replaced by LED wall washer. The structure and light distribution method of the existing LED wall washer are relatively traditional and old, the light-emitting angle is narrow, the light-emitting surface is small, the light-emitting effect is average, and the LED light source generally only passes through the light-transmitting cover once and then directly emits light. , the light is not uniform and soft enough, prone to glare and glare, the light utilization rate is low, the light efficienc...

AI Technical Summary

Problems solved by technology

The structure and light distribution method of the existing LED wall washer are relatively traditional and old, the light-emitting angle is narrow, the light-emitting surface is small, the light-emitting effect is average, and the LED light source generally only passes through the light-transmitting cover once and then directly emits light. , the light is not uniform and soft enough, prone to glare and glare, low light utilization rate, low light efficiency, insufficient irradiation intensity, poor luminous effect

In addition, both the LED light source and the driving device will generate heat. There is no isolation measure or structure between the LED light source and the driving device of the existing LED wall washer. The heat between the two is easy to interfere with each other and affect the service life of each other.
