Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly a kind of led light source module.
Background technology
CN201120127452.8 has announced " a kind of lamp holder of modularization intelligent street lamp and light source module thereof ".Its purpose provides a kind of more than one light source module that comprises; Can any a plurality of light source modules be combined through framework; Manufacture modularization and judicial convenience more; And can need select the light source module of number as required when using, thereby can be combined into plurality of specifications, satisfy the lamp holder and the light source module thereof of the modularization intelligent street lamp of multiple illumination needs.This technical scheme comprises: the light source cell main body of light source module comprises: radiator, cover, lens, waterproof apron and substrate.Wherein, the substrate of strip is an aluminium matter, and the one of which side is provided with a plurality of LED lamps, and opposite side then closely contacts with said radiator, and the most of heat that produces during with work is gone out through heat sink radiates.Mode through welding between radiator and the substrate is fixedly connected, and has saved the heat-radiating substrate in the conventional light source module, and the substrate of aluminum directly contacts with radiator, and one has alleviated the weight of light source module, and two come heat conduction more direct, and radiating effect is better.The side that substrate is provided with the LED lamp is covered with said lens, and lens are the integrated monoblock type lens of polymethyl methacrylate (being commonly called as lucite), and it converges effect to the light that the LED lamp sends, and can make the illuminating effect of light source module better.Also between lens and substrate, be provided with said waterproof apron, simultaneously in the lens arranged outside said cover.Cover is actually the box that a plastic material or metal material are processed, and on its two long margin frames, is evenly equipped with a plurality of fixing threaded holes, on the substrate also correspondence be provided with a plurality of fixing threaded holes.Through a plurality of screws cover and substrate are fixed during equipment, thereby lens are fixed between the two, make waterproof apron be compressed between the edge of lens and substrate simultaneously, then steam, dust etc. are difficult for entering into LED lamp place.Its weak point is that the substrate that the LED lamp is set must closely contact with said radiator through this substrate opposite side, and the most of heat that will produce in the time of could will working is gone out through heat sink radiates.Thereby overall structure is huge.
Summary of the invention
The purpose of this invention is to provide and a kind ofly around light source module framework outer wall, lay radiating fin, the led light source plate is dispelled the heat through its corresponding framework radiating fin when low-power or normal power and do not need to install in addition the led light source module that radiator dispels the heat.When another object of the present invention provides a kind of power when led light source and exceeds its low-power or normal power, select for use through the mode that radiator is installed in led light source plate bottom and dispel the heat.
Technical solution of the present invention is said led light source module, comprises framework, and its special character is:
The bottom of said framework forms step, and said step is provided with out the light shield and first sealing ring; The end face of said framework forms groove, and second sealing ring is embedded in the said groove, and the led light source plate is pressed on second sealing ring and through screw and is fixed on the framework; Said framework housing is positioned on four frames of peristome and convexes with radiating fin.
As preferably: between the step and framework end face of two relative frames of said framework, be provided with the mount pad of band screw, be connected with compressing tablet through screw on the said mount pad, said compressing tablet is pressed on out on the light shield.
As preferably: said compressing tablet end has to the compressing tablet head that goes out the bending of light shield direction.
As preferably: said framework end face is equipped with reference column, and said led light source plate and the corresponding position of said framework reference column are provided with the locating hole of prepackage location.
As preferably: said reference column and said locating hole have 2 pairs at least.
As preferably: many row LED bulbs of arranging by preset space length are installed on the said led light source plate.
As preferably: said led light source backboard face is welded with radiator.
As preferably: said radiator is at least one row's tabs formula radiator.
Compared with prior art, advantage of the present invention:
⑴ in the frame structure of light source module, and led light source only need dispel the heat through the radiating fin that the framework outer wall is laid when low-power or normal power, can meet the demands.
⑵ when exceed low-power or normal power when the power of led light source, select for use through the mode that radiator is installed in led light source plate bottom and dispel the heat.
⑶ because the framework panel is provided with radiating fin, and the light source module can be done very thinly like this, and weight is lighter.
