Abstract

The invention relates to the semiconductor illuminating technology, and in particular relates to a detachable LED (Light-Emitting Diode) light engine. The detachable LED light engine is formed by splicing two A units and a plurality of B units; each of two end surfaces of each A unit comprises a half of ridged grating, and the height of the grating of one end surface is higher than the heights of other ridged gratings; each of two end surfaces of each B unit also comprises a half of ridged grating, the heights of the ridged gratings of the two end surfaces are equal to those of the rest of ridged gratings and also equal to the height of a half of lower grating of the unit A; and the splicing mode of the two A units and the plurality of B units is of longitudinal abutted joint, the plurality of B units are arranged in the middle, and one ends of the two A units, provided with a half of higher grating, are both far away from the B units. The invention provides the detachable LED light engine which is simple in structure, convenient to manufacture and capable of being seamlessly spliced and extended.

Description

technical field [0001] The invention relates to semiconductor lighting technology, in particular to an assembleable LED light engine. Background technique [0002] LED lights have the characteristics of long life and power saving, and are more and more widely used in the field of lighting. Most of the existing light source modules adopt an integral structure, and when the light source modules are assembled into a lamp, each light source module is realized through a frame structure. [0003] For example, a LED street lamp disclosed in Chinese patent document CN 101105272A on January 16, 2008 includes a frame and a lighting module mounted on the frame. The lighting module includes a radiator, a substrate with an LED array, and a through-hole array. A PCB board and a lens cover provided with a lens array. The substrate is arranged on the lower surface of the radiator, the PCB is arranged on the outer surface of the substrate and is connected to the electrodes of the LEDs, the...
