Universal LED functional lamp

Abstract

The invention discloses a universal LED functional lamp which comprises a barrel. A universal interface is arranged on the upper portion of the barrel through a grid cover; a DC power supply is arranged in the grid cover and connected with an LED module; a cooling fin is arranged behind the LED module; and the cooling fin is of a structure in which the cross section is in a snowflake shape or is provided with a plurality of through holes and a plurality of fin bodies or guide tubes are arranged in the vertical direction. A reflecting cover is arranged on the front face of the LED module, and is in a horn opening shape, and the opening of the reflecting cover faces outwards. The inner face of the reflecting cover is coated with a reflecting film, and a plurality of reflecting rings are arranged on the reflecting cover. A light homogenizing plate or acrylic plate is arranged outside the reflecting cover through the barrel. The universal LED functional lamp is directly mounted, is simple in structure and convenient to mount, and has the application and popularization value; meanwhile, through the barrel and the structure of the multiple fin bodies or the guide tubes of the cooling fin, a flow guide chimney type cooling structure is formed in the barrel, the cooling purpose is achieved through the inherent effect of air, the universal LED functional lamp is simple in structure, economical and practical, and the cooling problem of the LED module is solved.

Description

technical field [0001] The invention relates to a lamp for lighting, in particular to a general-purpose LED functional lamp. Background technique [0002] LED lighting has been marketed due to its energy saving, environmental protection and long life. For the lighting lamp formed by multiple super bright LED modules, the heat is concentrated, and a radiator with good heat dissipation performance is required to ensure its normal operation, and the radiator also needs to ensure heat dissipation. In addition to the function, it is also conducive to the passage of ash and water. [0003] The patent No. 201020582888.1 of the LED lamp honeycomb heat sink has a plurality of internal threaded holes on the heat dissipation plate, and the internal thread holes are threadedly connected with the lower end of the heat pipe. The tube and the cooling plate are connected as a whole, the heat conduction tube is directly in contact with the heat source, and the heat dissipation effect is goo...

AI Technical Summary

Problems solved by technology

[0004] This patent effectively solves the problem of heat dissipation, but the heat dissipation plate needs to be processed, and the rainwater may soak the LED module on the heat dissipation plate, thereby shortening its life, and it is not conducive to cleaning when there is a lot of dust accumulation

[0005] The patent number is 2013202074477. Although a LED lamp solves the problems of ventilation, water and dust, it cannot solve the problem of weight. Because of its high power and prominent heat dissipation problems, the radiator must be made larger. Then Its cost is also relatively increased, which is not conducive to marketization
