Abstract

The invention provides a highly-integrated on-board driving wall washer. The highly-integrated on-board driving wall washer comprises a control module, a DC-DC constant-current driving module, an LEDlight source module and a heat dissipation lamp body. The LED light source module comprises an LED substrate and an LED lamp string; the LED substrate is installed on the front face of the heat dissipation lamp body. The control module comprises a first double-sided board, and components of the control module are mounted on the front surface of the first double-sided board; the DC-DC constant-current driving module comprises a second double-sided board, and components of the DC-DC constant-current driving module are mounted on the front surface of the second double-sided board; a threading hole is formed in the heat dissipation lamp body; a connecting hole corresponding to the threading hole is formed in the LED substrate; the first double-sided board of the control module, the second double-sided board of the DC-DC constant-current driving module and the LED lamp string of the LED light source module are attached to the front surface of the LED substrate; the middle area of the back surface of the first double-sided board is opposite to the connecting hole in the LED substrate; the pad in the middle area of the back surface of the first double-sided board is connected with a harness. The highly-integrated on-board driving wall washer is compact, the integration level is high, and cascade connection is convenient.

Description

technical field

[0001] The invention relates to a lamp, in particular to a highly integrated board-driven wall washer. Background technique

[0002] At present, the solution of DMX512 wall washer in the LED lighting industry mainly adopts the method of separating the DMX512 control module and the LED light source. The scheme needs to increase the flow line when meeting the requirements of multiple lamps connected in series, resulting in high cost of lamps and low production efficiency. On the premise of reducing costs and improving production efficiency, it is a development trend to integrate the DMX512 control module and the LED light source, and because there are many components in the DMX512 control module and DC-DC constant current drive module, the wiring is complicated and needs to be used FR4 double-layer board, and the power of the wall washer is relatively high. The LED light source part mainly uses single-sided aluminum substrate. The difficulty lies in how to int...
