Description
Technical field
The utility model relates to a kind of Down lamp.
Background technology
Existing Down lamp is used for indoor, in the embedded mode being arranged on ceiling or ceiling, uses.The light source that this Down lamp is used is mostly the LED(light emitting diode of environmental protection) light source, if the operating ambient temperature of LED light source is higher, in the life-span that can affect Down lamp and use element, the heat that therefore need send light source dispels the heat to reduce its operating ambient temperature.The use radiator having in existing Down lamp dispels the heat, and the perforate on the stack shell of Down lamp of passing through having is dispelled the heat.When using radiator to dispel the heat, heat can not distribute up hill and dale in Down lamp, and when perforate on stack shell, can make the water proof and dust proof of Down lamp poor, so those radiator structures are all not too reasonable.
Utility model content
The technical problems to be solved in the utility model is in order to overcome the unreasonable operating ambient temperature that makes Down lamp of tubular lamp radiating structure in prior art compared with high and affect Down lamp and use the defect in the life-span of element, a kind of Down lamp is provided, the radiator structure of this Down lamp is reasonable in design, and the heat that can produce light source dispels the heat thoroughly.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of Down lamp, it comprises a reflective mirror, one stack shell, one light source, one light source control module being electrically connected to this light source and an end cap, this reflective mirror and this end cap are fixed in respectively the two ends of this stack shell, the bottom center of this reflective mirror is provided with a through hole, this reflective mirror also comprises the peripheral wall surfaces of an annular, this light source is located in the through hole of this reflective mirror, its feature is, this Down lamp also comprises that one is positioned at this stack shell the radiator affixed with this end cap, the top outward of this peripheral wall surfaces forms a bending section, the bottom margin of this reflective mirror is provided with some louvres, this bending section is provided with some louvres that communicate with this stack shell, on this end cap, offer some louvres.
In this programme, louvre on radiator and reflective mirror and end cap is combined to use, make when the heat that uses radiator to produce this light source dispels the heat, can be by the louvre at stack shell two ends, dissipation of heat is extremely extraneous, and heat can not remained in Down lamp.In addition,, by the effect of extraneous air-flow, louvre and the louvre on end cap on reflective mirror can form cross-ventilation, are more conducive to the circulation of heat in Down lamp.
Preferably, this radiator is gilled radiator.This gilled radiator is commercially available to be obtained, and this gilled radiator area of dissipation is large, and radiating effect is better.
Preferably, on this light source, be covered with a Transparent Parts.This Transparent Parts is used for preventing piling up dust on this light source, uses this Transparent Parts can be so that the cleaning of later stage to this light source.
Preferably, this light source is some LED light sources, and described LED light source is distributed on light source substrate.
Preferably, this Down lamp also comprises at least one support of being located at this end cap one side.This support is for being fixed on a certain position by this Down lamp.
Preferably, the louvre on this end cap is circular hole and/or mounting hole.
Preferably, the louvre of the bottom margin of this reflective mirror is circular hole and/or mounting hole.
Positive progressive effect of the present utility model is: this Down lamp carries out heat loss through convection by the louvre at radiator and two ends, can realize distributing of the interior amount of heat of Down lamp, reduce the impact of higher operating temperature on Down lamp and use component life, also reduced the maintenance cost of bringing because of heat dissipation problem when Down lamp is installed on eminence.
