Abstract
This invention discloses one dissipation LED outdoor light lamp, which comprises lamp cover and circuit board fixed inside cover with one end fixed with dissipation device, wherein, the device is composed of inner and outer tubes and several L shape fin slices between two tubes and large and small ring block boards fixed on each fin wooden section set in lamp cover in inner and outer tubes; there are several wind-in holes and dissipation devices; other end of light cover is connected to other dissipation device through inner tube on lamp cover.
Description
Technical field:
The present invention relates to a kind of illuminating lamp, relating in particular to a kind of is the outdoor lighting lamp of light source with LED.
Background technology:
As everyone knows, LED is a kind of efficient luminous solid light source, and it has advantages such as energy-saving and environmental protection, life-span length, therefore is that the illuminating lamp of light source is competitively developed by More and more factories in recent years with LED.Yet present most LED outdoor lighting lamp generally all is the lampshade that adopts enclosed construction, because ventilation condition is bad, the difficulty of dispelling the heat, usually causes LED light to become blue, deepening, and luminance descends, the shortening in service life; Even more serious for outdoor lighting light fixture situations such as powerful street lamp, Landscape Lamps.Therefore, the temperature that improve ventilation condition, reduces in the lampshade is the key that prolongs lamp life.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the present invention aims to provide the heat dissipation LED outdoor lighting lamp of a kind of good heat dissipation effect, long service life.
To achieve these goals, the present invention by the following technical solutions: it comprises lampshade and is fixed on the interior circuit board of this cover; One end of lampshade is fixed with heat abstractor, this device by inner and outer pipe, fixing and be evenly distributed on polylith L type fin between two pipes, the large and small annular plate washer that is fixed on each fin major part section two ends constitutes, the some fresh air inlets that are arranged on the lampshade and between inner and outer pipe are communicated with this heat abstractor; Another heat abstractor that is fixed on the lampshade other end is communicated with exhaust vent on being arranged on lampshade by interior pipe.
The major part section of fin is trapezium structure, and large and small annular plate washer is a funnel-shaped structure; In lampshade near the fresh air inlet place be fixed be provided with on this plate of homogenizing plate some to discharge orifice; In lampshade, be provided with electric fan by temperature sensor control.
Compared with the prior art, the present invention is owing to utilized aerodynamic principle, on traditional lampshade, be provided with the heat abstractor that is used to dry with air inducing respectively, therefore can impel the circulation of air in the lampshade and heat is in time distributed, thereby avoided LED to cause light to become blue, deepening effectively owing to temperature raises, the defective that luminous efficiency descends has prolonged service life of light fixture greatly; Therefore the present invention does not need the additive decrementation electric energy owing to utilize the natural wind cooling.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view figure among Fig. 1;
Fig. 3 is the B-B cutaway view figure among Fig. 1.
Among the figure: pipe 5 outer tubes 6 fresh air inlets 7 little annular plate washer 8 big annular plate washers 9 in homogenizing plate 1 circuit board 2 lampshades 3 fins 4
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～3, be fixed with polylith circuit board 2 in the lampshade 3, each plate is provided with some LED lamps.Each fixes a heat abstractor at the left and right two ends of lampshade 3, and this device is by interior pipe 5, outer tube 6, fixing and be evenly distributed on the fin 4 of 4～8 L types between two pipes, the big annular plate washer 9 that is separately fixed at each left and right two ends of fin 4 major part sections, little annular plate washer 8 and constitute; Be arranged on that the some fresh air inlets 7 between interior pipe 5, outer tube 6 are communicated with the heat abstractor of left end on the lampshade 3, the heat abstractor of right-hand member is communicated with exhaust vent on being arranged on lampshade 3 by interior pipe 5.Should be noted that: pipe 5 air outlet in the air outlet of the outer tube 6 of right-hand member heat abstractor should be longer than its objective is for the air outlet place at interior pipe 5 to form swiftly flowing air-flow; This air-flow can form a negative pressure region among a small circle at the air outlet place of interior pipe 5, thereby accelerates the circulation of air in the lampshade 3.
In order to increase the speed of intake and quickening air-flow, the major part section of fin 4 can be made into trapezium structure, and correspondingly, big annular plate washer 9 and little annular plate washer 8 also should be made funnel-shaped structure; Major part section by funnelform big annular plate washer 9 and little annular plate washer 8 and each fin 4 constitutes 4～8 trumpet-shaped air-vents jointly.Consider weather calm or that wind-force is less, the electric fan by temperature sensor control can also be set in lampshade 3.In order to guarantee that heat radiation evenly, is fixed with homogenizing plate 1 near fresh air inlet 7 places in lampshade 3, this plate is provided with some to discharge orifice.
