Abstract

The invention belongs to the technical field of semiconductor illumination and particularly relates to an area array LED light engine with a seal cavity. The area array LED light engine comprises a light engine framework, a transparent lampshade, a silica gel seal ring, an area array LED light source module and a cooling plate, wherein the area array LED light source module clings to the cooling plate; a convex rail is arranged on one side of the light engine framework, and the transparent lampshade and the cooling plate are placed on the inner side of the rail; and the seal ring is in close contact with the convex rail, the transparent lampshade and the cooling plate, and a seal cavity is formed between the transparent lampshade and the cooling plate, so that the functions of preventing dust, water and body contact are played, and a clean and stable work environment is provided for the area array LED light source module. The area array LED light engine with the seal cavity can be flexibly equipped with lamp housings in different shapes and thus can be combined into LED lamps with various purposes. The area array LED light engine has great universality and interchangeability.

Description

technical field

[0001] The invention belongs to the technical field of semiconductor lighting, in particular to an area array LED light engine with a sealed cavity. Background technique

[0002] Lighting fixtures are usually composed of three parts: light source, power supply and lamps. The lamp includes three parts: the lamp body, the lamp cover and the lamp shade. The light source and power supply are usually installed and fixed on the housing of the lamp, so the lamp usually has a process of assembly in the factory, which not only increases the production cost, but also increases the maintenance cost.

[0003] For outdoor lamps, the lampshade is also required to be sealed to be waterproof and dustproof. Both the light source and the power supply are fixed on the housing of the lamp. If you want to maintain or replace the light source and power supply, you must disassemble the lamps installed on the fixed surface, send them to the workbench to remove the lamp cover of t...

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The described embodiments are only some of the embodiments of the invention. All other embodiments without creative achievements based on the embodiments of the present invention belong to the protection scope of the present invention.

[0024] Figure 4 It is an exploded view of the internal structure and components of an area array LED light engine 17 with a sealed cavity in the present invention. The inner side of the light engine frame 4 is provided with a convex fence 11, and the transparent lampshade 3 can be placed on the inner side of the convex fence 11. There is a concave silicone sealing ring 15 around the edge of the transparent lampshade 3 . The upper and lower planes of the silicone sealing ring 15 are respectively in close contact with the sides of the transparent lampshade 3 on the light engine frame 4 and the cooling plate 10 . The ar...
