Description
Technical field
The utility model belongs to outdoor lamp field, is specifically related to a kind of LED projector lamp of outdoor application.
Background technology
Along with the propelling of landscape engineering in city, the more and more of large-scale advertisement version, outdoor projection lamp is also used more and more widely.In order to reach good illuminating effect, this kind of outdoor use Projecting Lamp generally has higher brightness, and the drawback so brought is that light source heat production is many.Because this type of Projecting Lamp needs long-time unlatching night, if the heat of generation is drained not in time, the normal of lamp can be affected, time serious, can circuit be burnt out.
Some Projecting Lamps are provided with the through hole for dispelling the heat at back at present, but easily intake in these Projecting Lamps of rainy day, can have an impact to the circuit of inside, easily along bad.Therefore, need a kind of Projecting Lamp with fine heat sinking function, and the Projecting Lamp of rainwater-proof.
Utility model content
For deficiency of the prior art, the utility model provides a kind of LED projector lamp, and this Projecting Lamp has good heat sinking function.
The utility model is achieved through the following technical solutions.
LED projector lamp, comprise lamp body and base, described lamp body is provided with LED, it is characterized in that, the back of described lamp body is provided with cooling mechanism, described cooling mechanism comprises heat dissipation metal plate and the protecting crust being located at described heat dissipation metal plate outside, the bottom of described protecting crust is provided with air admission hole, top is provided with venthole, the back of described lamp body is also provided with the flashing board preventing described venthole from intaking, described flashing board extends across the top of described protecting crust from the back of lamp body, and is bent to form kink downwards.
In the utility model, heat dissipation metal plate can well take away the heat produced described in LED open-type, enters air outward and enters from air admission hole, rises from venthole and go out after heating, when simultaneously flashing board can ensure the rainy day, rainwater can not enter lamp body inside, prevents lamp body from damaging.
As preferably, between described kink and the lateral wall of protecting crust, be provided with fan.In order to increase throughput, being provided with fan, hot blast can being taken out of faster, there is better radiating effect.
As preferably, described lamp body front is also provided with secondary light source lamp and the inductor controlling described LED and open.In some use occasions, when surrounding does not have pedestrian through out-of-date, Projecting Lamp does not need to light, therefore be provided with secondary light source lamp and inductor in this preferred scheme, secondary light source lamp is lower-power lamps, nobody time, secondary light source lamp lights, when inductor, to have sensed that pedestrian enters out-of-date, controls LED and open, reach the object of power saving by internal circuit.
As preferably, described base is provided with fixing hole, and the sidewall of described base and lamp body is rotationally connected, and keeps stationary state by described knob.This structure facilitates the fixing of lamp body and angle adjustment.
Compared with prior art, the utility model has following beneficial effect: 1) have good radiating effect; 2) water inlet in lamp body when preventing the rainy day from using; 3) be provided with inductor, nobody time LED do not work, save electric energy.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.
See Fig. 1 to Fig. 5, LED projector lamp, comprise lamp body 1 and base 2, described lamp body 1 is provided with LED 11, the back of described lamp body 1 is provided with cooling mechanism, described cooling mechanism comprises heat dissipation metal plate 16 and the protecting crust 14 being located at described heat dissipation metal plate 16 outside, the bottom of described protecting crust 14 is provided with air admission hole 142, top is provided with venthole 141, the back of described lamp body 1 is also provided with the flashing board 15 preventing described venthole 141 from intaking, described flashing board 15 extends across the top of described protecting crust 14 from the back of lamp body 1, and be bent to form kink downwards, fan 17 is provided with between the lateral wall of described kink and protecting crust 14.
In present embodiment, described lamp body 1 front is also provided with the inductor 13 that secondary light source lamp 12 is opened with the described LED 11 of control, described secondary light source lamp 12 is weak light lamp, described inductor 13 is infrared inductor, described base 2 is provided with fixing hole 22, described base 2 is rotationally connected with the sidewall of lamp body 1, and keeps stationary state by described screwing of knob 21.
LED projector lamp of the present utility model has good radiating effect, and after fan 17 is opened, the flow direction of cooling blast is as illustrated by arrows 5, and rainproof, during use, can be fixed in suitable angle by lamp body 1, handled easily by screwing of knob 21.
Protection domain of the present utility model includes but not limited to above embodiment; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.
