Pressing fixture

Abstract

The invention provides a pressing fixture, which is used for pressing a solid-state light source array on a supporting part of a radiator. The pressing fixture comprises a pedestal and 2N pressing parts, wherein the pedestal is provided with a first surface and a second surface which are opposite to each other; the 2N pressing parts are formed on the second surface; each pressing part is provided with an oblique plane which tilts towards the central axis of the pressing fixture; the oblique planes of the 2N pressing parts and the parts of the second surface between the pressing parts together define a pyramid-shaped accommodating space. During pressing, the accommodating space is used for accommodating the supporting part of the radiator. A groove is formed in the middle of each pressing part; and N is an integer greater than or equal to 2.

Description

technical field [0001] The invention relates to a pressing jig for pressing a solid-state light source array to a heat sink. Background technique [0002] Currently, a solid-state lighting source is a semiconductor device that converts electrical current into a light source in a specific wavelength range. Solid-state lighting sources have the advantages of high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life, so they can be used as light sources and are widely used in the field of lighting. For details, see Joseph Bielecki et al. Literature 2007IEEE, 23 rd Thermal Considerations for LED Components in an Automotive Lamp in IEEE SEMI-THERM Symposium. Currently, lighting sources are widely used in lighting devices, such as light bulbs, classroom lights, street lights, and the like. [0003] However, the prior art uses the method of packaging solid-state light bulbs. Because the output is not lar...

AI Technical Summary

Problems solved by technology

[0003] However, the previous technology used the method of packaging solid-state light source bulbs. Because the output is not large, it is usually used to manufacture bulbs and assemble solid-state light sources by hand, which may cause problems related to the yield of light bulb products.

In other words, traditionally, to attach the array of solid-state light sources to the heat sink with heat-conducting glue, generally speaking, the array of solid-state light sources is attached to the heat sink by manual methods. The traditional manufacturing method , will require a large amount of manpower to process, and such a method will increase the production cost of the solid-state light source bulb

Moreover, it may be impossible to make products of consistent quality due to manual errors, resulting in a much lower product reliability of LED bulbs.
