Description
Technical field
The utility model relates to lighting device technical field, particularly relates to a kind of high-efficiency heat radiating LED Down lamp for throwing light on.
Background technology
Along with the develop rapidly of lighting device technology, the requirement of people to light fixture is also more and more higher, LED illumination product salable mainly concentrates on outdoor lighting, furnishing fields in the market, the product that LED is used for room lighting is fewer, what room lighting was with the most use is Down lamp, and it is less LED to be made the product that Down lamp is used for throwing light on.The light source that Down lamp adopts usually has incandescent lamp, mercury lamp and sodium vapor lamp, and these light sources have the shortcomings such as unstability, caloric value is large, service life is short, and light fixture volume is excessive in addition, and required installing space is large, and manufacturing cost is high, causes the waste of resource.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency that existing lighting device exists that caloric value is large, light source stability is poor, service life is short and volume is excessive, and provides a kind of high-efficiency heat radiating LED Down lamp for throwing light on.
The technical scheme that the technical problem proposed for solving the utility model adopts is:
A kind of high-efficiency heat radiating LED Down lamp for throwing light on, comprise lampshade and be located at the lamp housing at lampshade top, be provided with LED light source in the cavity of described lamp housing, described LED light source light direction is provided with the diffusion sheet be connected with lampshade or lamp housing, and the top of described lamp housing is also provided with radiator.
Described LED light source light direction is provided with the light source pressing plate for fixed L ED light source, and LED light source is fixed between light source pressing plate and envelope inner wall by screw by described light source pressing plate except wick portion.
Described lamp housing top is provided with the lamp housing cable-through hole that power supply source line passes, and described radiator top is also provided with the radiator cable-through hole corresponding with lamp housing cable-through hole.
Described radiator top is also provided with the pressure-ray film for fixed power source line, described pressure-ray film is fixed by screw and described radiator.
Described lampshade upper end open is provided with the step put for described diffusion sheet card, and be provided with reflector between described diffusion sheet and lamp housing, described diffusion sheet is clamped between described step and described reflector.
Described lampshade is provided with a pair elasticity mounting bracket.
Described lampshade medial surface is provided with anti-dazzle step.
The beneficial effects of the utility model are: have that good heat dissipation effect, little, the required installing space of overall volume are little, the advantage such as simple installation and low cost of manufacture.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
A kind of high-efficiency heat radiating LED Down lamp for throwing light on as shown in Figure 1, comprise lampshade 8 and be located at the lamp housing 2 at lampshade 8 top, LED light source 3 is provided with in the cavity of described lamp housing 2, described LED light source 3 light direction is provided with the diffusion sheet 6 be connected with lampshade 8 or lamp housing 2, diffusion sheet 6 both can be arranged in lampshade 8, also can be arranged in lamp housing 2, diffusion sheet 6 realizes even light-out effect of the present utility model.In order to the heat diffusion of LED light source 3 be gone out better, the top of described lamp housing 2 is also provided with radiator 1.
Described LED light source 3 light direction is provided with the light source pressing plate 4 for fixed L ED light source 3, and LED light source 3 is fixed between light source pressing plate 4 and lamp housing 2 inwall by screw 101 by described light source pressing plate 4 except wick portion.
Described lamp housing top is provided with the lamp housing cable-through hole that power supply source line passes, and described radiator 1 top is also provided with the radiator cable-through hole corresponding with lamp housing cable-through hole.Lamp housing cable-through hole and radiator cable-through hole are convenient to the power line that LED light source 3 is connected and are drawn from inside.
Described radiator 1 top is also provided with the pressure-ray film 9 for fixed power source line, described pressure-ray film 9 is fixed by screw 102 and described radiator 1.After the power line that the LED light source 3 passed from radiator 1 top connects adopts pressure-ray film 9 fixing, to save installing space.
The conveniently installation of diffusion sheet 6, described lampshade 8 upper end open is provided with blocks for described diffusion sheet 6 step put, and be provided with reflector 5 between described diffusion sheet 6 and lamp housing 2, described diffusion sheet 6 is clamped between described step and described reflector 5.While lampshade 8 is assembled with lamp housing 2, reach the object of synchronous fixing diffusion sheet 6 and reflector 5, adopt this optimum position, suitable distance is maintained between light pearl on diffusion sheet 6 and LED light source 3, reflector 5 can improve the efficiency of light energy utilization that LED light source 3 sends light, then the light that sends of LED light source 3 is by diffusion sheet 6, thus the light that the utility model lamp is sent is more all even bright.
Described lampshade 8 is provided with a pair elasticity mounting bracket 7.The hinged snap-arms of described elasticity mounting bracket 7, snap-arms there is a back-moving spring, during use, snap-arms is upwards overturn, LED down is filled in ceiling installing hole, under action of reset spring, snap-arms overturns reset downwards, thus makes snap-arms and lampshade 8 outer be held on ceiling upper surface and lower surface respectively, thus the utility model is fixed on ceiling quickly and easily.
Described lampshade 8 medial surface is provided with anti-dazzle step.The dazzle sent through diffusion sheet 6 can be evacuated effectively by anti-dazzle step, thus effectively prevents dazzle.
The above embodiment only have expressed embodiment of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; in every case the technical scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection domain of the present utility model.
