Preferably, the bell-mouthed both sides external of described cylindrical shell part is respectively equipped with jamming seat, and 2 clamp button of the spring are fixed by the card entry slot that snaps in this jamming seat respectively.
Preferably, the straight cylinder of this cylindrical shell part is provided with multiple bolt fixed legs, and the bottom surface of this LED light source component palette and heat radiating cup respectively correspondence is provided with screw, locks the bolt fixed leg of the straight cylinder of cylindrical shell part by bolt.
Preferably, on the barrel of the straight cylinder of described cylindrical shell part, be also provided with a through hole, this through hole is inserted in a wire seal cock body.
The advantage of LED Down lamp of the present utility model is with low cost, and radiating effect can meet use needs.
Accompanying drawing explanation
Fig. 1 is each parts decomposition explosion figure of the LED Down lamp of an embodiment.
Fig. 2 is the general assembly drawing (angle one) of this embodiment.
Fig. 3 is the general assembly drawing (angle two) of this embodiment.
Fig. 4 is the cutaway view of this embodiment.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1-Fig. 4, for the LED Down lamp of the utility model one preferred embodiment, comprise the outside of the Down lamp main body that a nozzle fixture 1, a cylindrical shell part 2 and a pair of clamp button of the spring 7 form, and be arranged at lens 3, heat radiating cup 6, LED light source component palette 4 and the LED driving power (not shown) of Down lamp body interior.Wherein, cylindrical shell part 2 is that straight cylinder 202 upper ends horn mouths 201 of connection in one of bottom form, 2 clamp button of the spring 7 are individually fixed in cylindrical shell part 2 both sides external, heat radiating cup 6 is sheathed and be fixed in the horn mouth 201 of cylindrical shell part 2, LED light source component palette 4 is fixed on the bottom of this heat radiating cup 6, LED driving power is arranged in the straight cylinder 202 of cylindrical shell part 2, LED driving power is electrically connected to LED light source component palette 4 by wire, and this lens 3 is arranged at the opening of heat radiating cup 6 and is interfixed and press solidly with the horn mouth 201 of cylindrical shell part 2 by nozzle fixture 1.Wherein, nozzle fixture 1 and cylindrical shell part 2 are non-conductive plastic material, and heat radiating cup 6 adopts heat-conducting metal material.Like this, because LED driving power is arranged in the straight cylinder 202 of cylindrical shell part 2 of plastic material, and heat radiating cup 6 is set in the horn mouth 201 of cylindrical shell part 2 of plastic material.Therefore, the outside of whole Down lamp main body is nonconducting working of plastics, and LED driving power can adopt ordinary light source to realize, and without using insulating power supply, has reduced power supply cost; Heat radiating cup 6 adopts metal material simultaneously, and nozzle fixture 1 and cylindrical shell part 2 all adopt plastic material, also greatly reduce material cost.
Preferably, the both sides external of the horn mouth 201 of this cylindrical shell part 2 is respectively equipped with 21,2 clamp button of the spring 7 of jamming seat and by the card entry slot that snaps in this jamming seat 21, fixes respectively.The straight cylinder 202 of this cylindrical shell part 2 is provided with multiple bolt fixed legs, the bottom surface of this LED light source component palette 4 and heat radiating cup 6 respectively correspondence is provided with screw 41,61, by bolt 5, lock the bolt fixed leg of the straight cylinder 202 of cylindrical shell part 2, realized LED light source component palette 4 simultaneously and fixed with the fixing and heat radiating cup 6 of heat radiating cup 6 and the sheathed of horn mouth 201 of cylindrical shell part 2.
In addition, for the good sealing effectiveness that gets up, on the barrel of the straight cylinder 202 of cylindrical shell part 2, be also provided with a through hole 22, this through hole 22 is inserted in a wire seal cock body 8, for the electric wire of the LED power supply in straight cylinder 202 straight cylinder 202 that stretches through out, seals when outside; This wire seal cock body 8 can adopt quality of rubber materials to make.
It should be noted that, the inner cup wall of this heat radiating cup 6 serves as the reflecting surface of LED Down lamp simultaneously, the smooth of should polishing to obtain.This heat radiating cup 6 adopts radiating effect to teach good metal material to make simultaneously, as aluminium etc.The heat of the multiple illuminators 41 that have on LED light source component palette 4 conducts to the heat radiating cup 6 of metal by the substrate (being generally aluminium sheet or copper coin) of LED light source component palette 4.Although cylindrical shell part 2 adopts non-metallic material, the heat radiating cup 6 of metal still can carry out heat exchange with external environment by cylindrical shell part 2, substantially can meet the heat radiation requirement of LED Down lamp.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
