Description
Technical field
The present invention relates to LED, refer specifically to the radiating subassembly of a kind of LED.
Background technology
Along with the various advantages such as the energy-saving and environmental protection of LED lamp, high brightness, color rendering properties are high are day by day accepted and admit
When, LED lamp is just widely used in various occasion, such as commercial lighting, office lighting, industrial lighting etc., then by
In the feature of LED self, therefore the heat dissipation problem of LED is the most increasingly paid attention to by each manufacturer.
LED lamp tube originally all can be coated with last layer heat-conducting glue to preferably dispel the heat at the back side of light source board, makes light source board
Can be close on the radiating surface of support, beneficially LED lamp bead heat radiation, but heat-conducting silicone grease has shortcoming aging, that become dry, thus can
The heat conductivity making heat conductive silica gel reduces, and have impact on the heat radiation of LED lamp bead, and needs wire mark when using, without net
Print, it is necessary to smear by hand, smear by hand and not only expend raw material but also waste man-hour.
Summary of the invention
For the deficiencies in the prior art, it is desirable to provide the radiating subassembly of a kind of LED, it is possible to solve to use heat conduction
The problem of the time-consuming expense material occurred during the problem of the light fixture cost increase that adhesive tape comes and use heat-conducting glue.
For solving the problems referred to above, the present invention provides the radiating subassembly of a kind of LED, and LED includes lamp bracket, described lamp bracket
On offer bracket groove, described radiating subassembly includes PC diffuser, light source board and support heat sink, described PC diffuser and light
Source plate clamping is arranged in bracket groove, and the upper surface of light source board, described support heat sink are withstood in the lower end of described diffuser
Being fixedly mounted on lamp bracket, described support heat sink is fitted and connected with light source board.
Described support heat sink is aluminium base, and the lower end of described support heat sink is provided with fin fin, described
Fin fin is one-body molded with support heat sink.
Described PC diffuser is dome-type PC diffuser, and the lower end of described PC diffuser is provided with connecting portion.
Described connecting portion is funnel-form, described connecting portion and PC diffuser integrated injection molding.
Beneficial effect: the present invention had both solved what the light fixture cost using heat-conducting glue to bring increased by technique scheme
Problem, the problem simultaneously also solving the time-consuming expense material occurred during using heat-conducting glue, it is truly realized energy-conserving and environment-protective.
Accompanying drawing explanation
The normal cross-section structural representation of Fig. 1 present invention.
Description of reference numerals: PC diffuser 1, light source board 2, support heat sink 3.
Detailed description of the invention
The detailed description of the invention of the present invention is described below in conjunction with Figure of description:
The radiating subassembly of a kind of LED, LED includes lamp bracket, and described lamp bracket offers bracket groove, described heat radiation group
Part includes that dome-type PC diffuser 1, light source board 2 and support heat sink 3, described PC diffuser 1 are arranged on light source board 2 clamping
In bracket groove, the lower end of described PC diffuser 1 is provided with connecting portion, and described connecting portion is funnel-form, connecting portion and PC printing opacity
Covering 1 integrated injection molding, described connecting portion withstands the upper surface of light source board 2；Described support heat sink 3 is fixedly mounted on lamp
On frame, described support heat sink 3 is aluminium base, and the lower end of described support heat sink 3 is provided with fin fin, described fin
Type fin is one-body molded with support heat sink 3, and described support heat sink 3 is fitted and connected with light source board 2, makes LED lamp bead
Heat can in time by the fin fin on support heat sink 3 and cross-ventilation and Quick diffusing is gone out.
The above, be only present configuration preferred embodiment, and not the technical scope to the present invention is made any
Limit, therefore every any trickle amendment, equivalent variations and modification above example made according to the technical spirit of the present invention,
All still fall within the range of technical scheme.
