Solid-state light source heat-dissipation metal shell as well as manufacturing method and manufacturing mold thereof

Abstract

The invention provides a solid-state light source heat-dissipation metal shell as well as a manufacturing method and a manufacturing mold thereof. In order to lower the structural member cost and improve the heat-dissipation performance of a solid-state light source, the invention provides a heat-dissipation metal shell (1) as well as a manufacturing method and a manufacturing mold, wherein a metal side wall (2) of the heat-dissipation metal shell (1) is provided with a ventilation window (3); the ventilation window (3) is of a louver-type or staggered structure with formation convex teeth for axial pushing formation; all the formation convex teeth are fixed in a concave mold; a convex mold is provided with a corresponding formation groove; the convex teeth move axially so as to push the metal shell to deform inward, so that an air vent is formed. The used mold is simple in structure, is capable of realizing multi-station continuous mold stamping forming, and is high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of solid-state light source heat dissipation, and in particular relates to a solid-state light source radiator which adopts natural convection heat dissipation and uses shell structural parts as heat sinks, a manufacturing method and a mold thereof. technical background [0002] Due to its energy saving and environmental protection, LED (solid-state light source) is considered to be the light source for the next generation of human lighting, but the key obstacle hindering the popularization of LED lighting is: the cost 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. As the price of LED light sources decreases step by step, the cost of structural parts will be the main cost of LED lighting, so reducing the cost of structural parts...

AI Technical Summary

Problems solved by technology

Since the side wall of the lamp housing is generally barrel-shaped, if the above method is used to open the ventilation window on the side wall, the production efficiency will be low. If the stamping process is used to realize one-time forming, the movement direction of the convex teeth 103 is the same as the movement direction of the punch head ( Also the axial direction of the housing) is inconsistent, and should be vertical, each convex tooth 103 must move relative to each other, it cannot be as figure 1 , 2 One integral part shown, such a mold structure is very complex, and it may not be possible to produce a practical and reliable mold
