Description

LED bay light

Technical field

The utility model relates to a kind of bulkhead lamp capable, especially a kind of Novel LED bulkhead lamp for integrated mill, mining area, gas station.

Background technology

Bulkhead lamp capable is be used in the production operation district of mine at first, present bulkhead lamp capable in construction site, integrated mill, gas station, expressway charge station installation real use more and more general.Along with national economy and social development and progress, constantly advance and improve along with light trade, what in initial bulkhead lamp capable, light source adopted is incandescent lamp, and the incandescent lamp energy consumption high life is short, and illuminating effect is bad; Just adopt electronic energy-saving lamp as the light source of bulkhead lamp capable subsequently, electronic energy-saving lamp has certain energy-saving effect, but the lifting that the effect of illumination obtains is less, and electronic energy-saving lamp generally comprises sodium vapor lamp bulkhead lamp capable, mercury vapor lamp bulkhead lamp capable, therefore electronic energy-saving lamp easily produces the heavy metal element of hostile environment in the process used; Just occurred LED illumination technology subsequently, in view of the relative energy-saving of LED bay light, do not have the generation of harmful substance in use procedure, the application of high-power LED bulkhead lamp capable is also more and more extensive.

Existing LED bay light in use still comes with some shortcomings: the illumination zone due to bulkhead lamp capable needs wider, the intensity of illuminating ray needs larger, therefore LED lamp bead that power is larger all can be selected as the lamp source of LED bay light, therefore the heat of the power supply generation of bulkhead lamp capable is a lot, and the heat dissipation problem at power supply place is not also solved very well; And the heat at power supply place also can be delivered on lampshade, the life-span of LED chip is very serious by the impact of temperature, and temperature often raises 10 DEG C, and the light decay life-span of LED chip will shorten half, makes the quality of LED bay light and life-span be difficult to ensure; Although the illuminating effect of LED bay light is better, but the light irradiated is too concentrated, and the situation of blind area appears in the irradiation area made, and does not reach good illuminating effect, if increase the installation quantity of LED bay light, the cost using LED bay light can be strengthened;

Utility model content

For the problems referred to above of the prior art, the utility model proposes a kind of LED bay light, the utility model solves the technical problem that the heat radiation of LED bay light power unit, LED chip service life, short and LED bay light irradiation light was too concentrated.

The technical solution of the utility model is: a kind of LED bay light comprises lamp socket, described lamp socket is provided with power supply installation cavity, below described power supply installation cavity, heat abstractor is installed, the bottom surface of described heat abstractor is provided with circuit board, described circuit board is welded with several LED lamp bead, the top of described lamp socket is provided with link; The lower end of described heat abstractor is provided with lampshade, is provided with power supply in described power supply installation cavity, and described power supply installation cavity is sealed by heat conduction embedding silica gel, and described circuit board is provided with lens, and the top of described lamp socket is connected in integrally forming by multiple convex surface.

Further, described lampshade is aluminium reflection shield.

Further, described lens are silica-gel lens.

Compared with prior art, the beneficial effects of the utility model are:

1. the utility model is by being sealed in power supply installation cavity with heat conduction embedding silica gel by power supply, the aluminium shell by heat conduction embedding silica gel the heat that power supply produces being directly delivered to power supply installation cavity directly dispels the heat, the heat dissipation problem at power supply place is well solved, effectively ensure that power supply can normally work, too increase the service life of power supply.

The top of the lamp socket 2. in the utility model is connected and composed by multiple convex surface, adds the surface area of the end face of lamp socket, adds the area of dissipation of power supply place heat, and power supply place heat can be distributed more timely.

3. at several LED lamp bead places, silica-gel lens has been installed in the utility model, first silica-gel lens is high temperature resistant, silica-gel lens changes the light extraction efficiency of LED light source, the optical field distribution changing LED light source, increase optical reflection, reduces light loss and improve light efficiency, the illumination zone making LED light source bulkhead lamp capable is larger, illumination brightness brighter; Lampshade is aluminium reflection shield, improves the utilization rate of LED light source bulkhead lamp capable light, makes the illuminating effect of LED light source bulkhead lamp capable better.

Detailed description of the invention

Below in conjunction with drawings and Examples, the technical scheme in the utility model is further illustrated.

With reference to accompanying drawing 1,2, the utility model comprises lamp socket 1, lamp socket 1 is provided with power supply installation cavity 2, heat abstractor 3 is installed below power supply installation cavity 2, heat abstractor 3 is except dispelling the heat for the heat produced that LED bay light thrown light on, can also dispel the heat to the partial heat that power supply produces, the chip of the heat preventing power supply from producing to LED lamp bead impacts; The bottom surface of heat abstractor 3 is provided with circuit board 4, circuit board 4 is welded with several LED lamp bead 5, the top of lamp socket 1 is provided with link 6, link 6 be arranged to be easily installed on the crossbeam of building; The lower end of heat abstractor 3 is provided with lampshade 7, in power supply installation cavity 2, power supply is installed, power supply installation cavity 2 is sealed by heat conduction embedding silica gel, power supply is in closed space, and heat conduction embedding silica gel fast the heat that power supply produces can be delivered to power supply installation cavity aluminium shell on dispel the heat; Circuit board 4 is provided with lens 8; Lens 8 change the light extraction efficiency of LED light source, the optical field distribution changing LED light source, increase optical reflection, reduce light loss and improve light efficiency, make the illumination zone of LED light source bulkhead lamp capable larger, illumination brightness brighter, the top of lamp socket 1 connects in integrally forming by multiple convex surface, add the surface area of the end face of lamp socket 1, add the area of dissipation of power supply place heat, power supply place heat can be dispelled the heat further timely.

Lampshade 7 is aluminium reflection shield, and the light that LED bay light produces can reflect by aluminium reflection shield further, and can improve the utilization ratio of LED bay light light, make the better effects if that LED bay light is thrown light on, the scope of illumination is wider.

Lens 8 are silica-gel lens, and silica-gel lens heatproof is high, and the heat that LED bay light produces can not cause damage to silica-gel lens; And can be fixed by the welding manner of Reflow Soldering, easy to use.
