Description
Technical field
The utility model relates to a kind of high-efficiency radiator structure of LED Down lamp, belongs to technical field of semiconductor illumination.
Background technology
Along with the lifting of LED performance and the decline of cost, obtained fast development with LED as the illuminating product of light source, and replaced the traditional lighting product gradually and be applied to some indoor and outdoors illumination places.In the traditional lighting product, Down lamp is the comparatively general lighting source of a kind of application.The light source that Down lamp adopted is generally light sources such as Halogen lamp LED, electricity-saving lamp, the light of these full angle luminous light source is after the emission through Down lamp lamp wall, the actual light efficiency of whole lamp is lower, therefore, adopts the stronger LED of directionality to be used for Down lamp and will have the considerable energy saving advantage.
But the problem that LED self exists is that the light fixture light efficiency is subjected to the influence of junction temperature of chip bigger.Higher junction temperature of chip will cause light efficiency to occur obviously descending, and can have influence on the service life of LED Down lamp.Therefore, the heat dissipation problem of solution LED Down lamp is most important for the performance that promotes the LED Down lamp.Because traditional lighting source is to rely on the hyperthermia radiation effect realization of filament self luminous, therefore, does not have the needs of heat radiation.This causes can being subjected to the restriction of Down lamp size when replacing the traditional lighting light source with LED, can be less for the heat-dissipating space that utilizes in the LED Down lamp thereby cause.
Therefore, how making full use of the structure space of traditional Down lamp, make the LED Down lamp can satisfy the standard-required of illumination, can provide enough heat-dissipating spaces again, is a difficult problem of present LED cylinder lamp structure design.
General LED Down lamp is directly to be provided with a series of radiating fins at the back side of lamp wall, and the air by radiating fin and Down lamp back carries out heat loss through convection.Because Down lamp generally is to be embedded on the furred ceiling of ceiling, so the radiating effect of the radiator structure of this LED Down lamp is very limited.
The utility model content
The purpose of this utility model is exactly at above shortcomings in the prior art, and a kind of a kind of high-efficiency radiator structure that can strengthen the LED Down lamp of Down lamp fin heat radiation is provided, and improves the reliability of LED Down lamp.
The purpose of this utility model is achieved in that a kind of high-efficiency radiator structure of LED Down lamp, comprises the radiating fin on Down lamp body and the Down lamp body, it is characterized in that, the lamp wall of described Down lamp body is provided with a series of air vents that link to each other with radiating fin or ventilation slot.
The lamp wall of described Down lamp body is provided with lamp wall and following lamp wall, and the axial line of upper and lower lamp wall overlaps with the axial line of Down lamp body, and last lamp wall diameter is less than following lamp wall diameter, and last lamp wall is provided with the led light source stationary plane.
Described air vent or ventilation slot are arranged between the upper and lower lamp wall and between the two adjacent radiating fins.
(Down lamp back or Down lamp body back) extends to down lamp wall top to the periphery diffusion to described radiating fin from last lamp wall back, and radiating fin and the cross-over connection of upper and lower lamp wall are connected into one.
The utility model is rational in infrastructure simple, manufactures easily, and good heat dissipation effect has improved the light efficiency of LED Down lamp, prolongs the service life of LED Down lamp.A series of air vents that link to each other with radiating fin or ventilation slot are set on the lamp wall of Down lamp, air can directly be incorporated into the cold air of Down lamp bottom in the radiating fin by the heat radiation through hole, thereby strengthened the radiating effect of radiating fin, helped improving the service life of LED Down lamp.The radiating fin of LED Down lamp is the thin plate sheet that is distributed in all cloth at Down lamp back.What be different from general LED Down lamp is, the length of the radiating fin of LED Down lamp of the present utility model is at the place, centre position that extends to Down lamp lamp wall, and promptly air vent or ventilation slot place just stop.And general LED Down lamp must extend to radiating fin on the lamp of Down lamp along the place for enhance heat.
Therefore, heat spreader structures of the present utility model by the enhance heat effect of wind hole or ventilation slot, thereby can reduce the length and the quantity of the radiating fin of Down lamp.Under the situation of equal-wattage, adopt heat spreader structures of the present utility model, can effectively reduce the weight of Down lamp, and whole modulated structure is ingenious, attractive in appearance succinct, the cooling system of reinforcement can effectively prolong the service life of LED Down lamp.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the utility model.
Be depicted as the heat spreader structures of the LED Down lamp of present embodiment as Fig. 1-4.Down lamp lamp wall 1 is divided into lamp wall and following lamp wall two parts at the place, centre position of lamp wall, and two parts lamp wall 1 has different internal diameter sizes, can be for the passage of air discrepancy thereby form between two parts lamp wall.Be distributed with radiating fin 2 on the top of lamp wall 1, radiating fin 2 stops at the center-aisle place of lamp wall 1, thereby passage is divided into a plurality of heat dissipation ventilations hole or ventilation slot 3.Led light source is fixed on the led light source stationary plane 4 of lamp wall.
The heat spreader structures of using present embodiment is during to the LED Down lamp, and led light source will be distributed on the light source stationary plane 4, be stamped optical element or lampshade above, and the height of optical element or lampshade is no more than heat dissipation ventilation hole or ventilation slot 3.Like this, the radiating fin 2 that is heated just can suck cold air the back side of Down lamp endlessly by heat dissipation ventilation hole or ventilation slot 3, has strengthened the radiating fin of Down lamp and the heat exchange action of external environment.Therefore, the heat spreader structures of present embodiment is important breakthrough and the innovation to general LED Down lamp heat spreader structures.
