A light engine module that can freely replace cob light sources and reflector components

Abstract

The invention relates to a light engine module capable of freely replacing a COB (chip on board) light source and a reflection cup component, and belongs to the technical field of LED (light-emitting diode) illuminating lamps. The light engine module comprises a radiator, a COB light source and a COB light source bracket, and also comprises a reflection cup component, a cup lid and a closing ring, wherein the reflection cup component is propped against the COB light source bracket through the cup lid; the cup lid comprises a cup lid cup body and a cup lid turned-over edge; the cup lid turned-over edge is arranged at one end of the cup lid cup body; a locating hole is formed in the cup lid turned-over edge while the closing ring is provided with a BOSS locating post corresponding to the locating hole; meanwhile, more than one group of heat dissipation channels are arranged at the other end, which is opposite to the cup lid turned-over edge, of the cup lid cup body along the circumference. The light engine module not only can carry out two-way vertical convection heat dissipation, but also is simple in structure and low in cost, meanwhile, the cup lid of the light engine module is convenient to change, and the production cost is low.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to the technical field of LED lighting fixtures which can freely replace a COB light source and a light engine module device of a reflector assembly. Background technique [0002] Most of the existing LED downlights are integrated designs. In order to be more in line with the standardization requirements of Zhaga, people in the industry have begun to design the modular structure of the light engine. The modular design method will firstly change the traditional integrated design, and secondly To lay the foundation for the subsequent establishment of light engine standards, making it more inclined to standardized design. [0003] Looking at the LED downlights on the market, most of them have not yet entered the modular design. Some of the more advanced ones have introduced the design concept of light engine, and have successfully produced some LED engine downlights. Most LED engines ...

Problems solved by technology

4. The mass of the engine module is large - that is, the large mass brought by the large volume of the COB type cannot be effectively controlled

Although it solves the unidirectionality of the heat dissipation direction and realizes convective heat dissipation up and down, the invention has the following problems: since the height of the reflector (also known as the reflector assembly) is generally fixed, it has been The finished products are out of control of the customers who use them. When we need to replace other brands of COB light sources, we need to re-pair the corresponding reflectors. The re-paired reflectors will affect the original shell (also known as the cup cover). Therefore, it is necessary to replace the cup cover, and the production process of this cup cover is complicated and the cost is relatively high. Since the COB light sources of each brand are different, the matching reflectors are also different, so it is impossible for every COB light source to be used. To produce the corresponding cup cover, but to produce the cup cover for a certain COB light source alone, the mold produced needs to be customized again, so the replacement cost is high
