Semiconductor light source radiator and light source engine

Abstract

The invention aims to reduce the cost of a structural member and improve the heat dissipation performance, and provides a semiconductor light source radiator and a light source engine. The semiconductor light source engine is characterized in that a, the structure (the casing) serves as a cooling fin, namely a radiating metal casing (1) machined and formed through punching a sheet metal (aluminum plate), so that the machining cost and material cost are reduced; b, the wall thickness of the radiating metal casing is optimized to further reduce the material cost; c, the metal side wall (2) is formed through stretching a rear metal casing (9) or / and a front metal casing (4), a ventilating window (3) adopting a louver type or staggered arrangement type structure is formed, the ventilating ratio is not less than 0.20, so that air in natural convection flows smoothly, and the radiating performance is remarkably improved; and d, a reflector (31) is equipped, and most light emitted from a semiconductor light source (6) is light reflected by the reflector, so that the light source engine can solve the problem of dazzling light.

Description

technical field [0001] The invention belongs to the technical field of semiconductor light source heat dissipation and lighting, and in particular relates to a semiconductor light source radiator and a light source engine that adopt natural convection heat dissipation and use shell structural parts as heat sinks. technical background [0002] LED (semiconductor light source) is considered as the next-generation lighting source for human beings because of its energy saving and environmental protection. However, the key obstacle hindering the popularization of LED lighting lamps and replacing traditional lighting lamps is: the cost of LED lighting lamps is too high. The cost of LED lighting can be divided into three parts: LED light source, power supply and structural parts. The structural parts include radiators, and the cost of structural parts mainly comes from the radiators. At present, the cost of structural parts has accounted for as much as one-third of the total cost o...

Problems solved by technology

[0005]Current LED lighting uses the shell structure as a heat sink, but due to the above problems, no attention or special attention has been paid to ensuring the smooth flow of air during product design, such as : There is no convection ventilation window on the shell cover, even if there is a convection ventilation window, but the opening is not sufficient; it does not take into account that when the axis installation angles of the lamps are different, it will affect the smooth flow of natural convection upward flow

Therefore, the heat dissipation performance of the lamp is poor, and the surface of the lamp shell is not fully utilized as a heat dissipation surface, and additional heat sinks need to be added, resulting in a high cost of structural materials for the lamp
