Abstract
The utility model provides a kind of LED support light fixture, comprises lampshade, base shell, and described lampshade bottom and base shell junction are provided with installation portion, and described installation portion is that the projection that the downward broken line of lampshade extends closes up, and described projection closes up and is provided with draw-in groove; Light source board is connected in draw-in groove; Described base shell is provided with the mounting groove mated with the installation portion of lampshade, and described installation portion is fixedly mounted in described mounting groove; Described base shell is alloy profile, and described lampshade is plastic lamp shade.The heat radiation of the utility model light source board is good; While the utility model heat dispersion is good, also meet the requirement of 3000V safety certification.
Description
Technical field
The present invention relates to a kind of LED support light fixture.
Background technology
Existing LED frame lamp has two classes, one class is widely used aluminium alloy post LED lamp on market, its withstand voltage only has about 1500V, although good heat dispersion performance, but only meeting some areas uses three to insert (line with ground) power supply, cannot meet the safety certification requirement of more than 3000V; Equations of The Second Kind improves on the basis of the first kind, and for reaching the safety certification requirement of 3000V, lampshade and base shell all adopt plastics, but it exists the drawbacks such as heat dispersion is not good.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of perfect heat-dissipating, and can reach the LED support light fixture of 3000V safety certification requirement, and for this reason, the utility model provides following technical scheme:
A kind of LED support light fixture, comprise lampshade, base shell, described lampshade bottom and base shell junction are provided with installation portion, and described installation portion is that the projection that the downward broken line of lampshade extends closes up, and described projection closes up and is provided with draw-in groove; Light source board is connected in draw-in groove; Described base shell is provided with the mounting groove mated with the installation portion of lampshade, and described installation portion is fixedly mounted in described mounting groove; Described base shell is alloy profile, and described lampshade is plastic lamp shade.
In the past by direct for light source board clamping base shell top, lampshade covered in base shell both sides again, and whole base shell upper surface all wraps into lampshade, in order to reach the requirement of 3000V safety certification, base shell and lampshade all adopt plastics, and the heat dispersion of plastics is poor, cause light source board to dispel the heat difficult.The projection closing in grafting of the installation portion of the utility model lampshade bottom light source board, lampshade is plastic construction, light source board is arranged in lampshade to play and improves class of insulation effect, can reach the requirement of the safety certification of 3000V.Meanwhile, base shell have employed alloy material, has close contact, perfect heat-dissipating bottom light source board with pedestal.Further, the utility model projection closes up little with the contact surface of base shell, and the full-enclosed that before comparing, radiator is built-in, the utility model half-packaging, heat dispersion is improved further.
On the basis adopting technique scheme, the present invention also can adopt following further technical scheme:
The mounting groove of described base shell is undercut shape, and described mounting groove bag fastens described installation portion.Bayonet type grafting makes installation firmly more convenient.
It is aluminium base that the base material of described light source board comprises, heat conduction PCB and epoxy glass-fiber-plate etc., but is not limited to other sheet material of above kind.
Owing to adopting technical scheme of the present invention, beneficial effect of the present invention is: the heat radiation of (1) the utility model light source board is good; (2) the utility model heat dispersion good while, also meet the requirement of 3000V safety certification.
Accompanying drawing explanation
Fig. 1 is a kind of LED support light fixture profile provided by the invention.
Fig. 2 is a kind of LED support lamp assembled constructed profile provided by the invention.
Detailed description of the invention
With reference to accompanying drawing, a kind of LED support light fixture, comprises lampshade 3 bottom described in lampshade 3, base shell 1 and base shell 1 junction is provided with installation portion, and described installation portion is that lampshade 3 projection that broken line extends downwards closes up, and described projection closes up and is provided with symmetrical draw-in groove; Light source board 2 is connected in draw-in groove; Described base shell 3 is provided with the mounting groove mated with the installation portion of lampshade 1, and described installation portion is fixedly mounted in described mounting groove; Described base shell is alloy profile, and described lampshade is plastic lamp shade.
In the past by direct for light source board clamping base shell top, lampshade covered in base shell 1 both sides again, and whole upper surface of outer cover all wraps into lampshade, in order to reach the requirement of 3000V safety certification, base shell and lampshade all adopt plastics, and the heat dispersion of plastics is poor, cause light source board to dispel the heat difficult.The projection closing in grafting of the installation portion of the utility model lampshade 3 bottom light source board 2, light source board 2 is mounted on lampshade 3, instead of on base shell 1, former full-enclosed of comparing, the utility model half-packaging, heat radiation is improved.
The mounting groove of described base shell 1 is undercut shape, and described mounting groove bag fastens described installation portion.Bayonet type grafting makes installation firmly more convenient.
It is aluminium base that the base material of described light source board comprises, heat conduction PCB and epoxy glass-fiber-plate etc., but is not limited to other sheet material of above kind.
The projection closing in grafting of the installation portion of the utility model lampshade bottom light source board, lampshade is plastic construction, and light source board is arranged in lampshade can play insulation effect, can reach the requirement of the safety certification of 3000V.Meanwhile, base shell have employed aluminum alloy materials, perfect heat-dissipating.While the utility model heat dispersion is good, also meet the requirement of 3000V safety certification.
Above-describedly be only enforcement example of the present utility model, when can not limit according to this utility model for advocate scope, any interest field Inner of being authorized at the utility model and based on the change made under doctrine of equivalents or amendment, should be considered as implementing invention of the present utility model.
