Abstract
The invention discloses an LED spotlight which comprises a light cap, a light cup and a plug. The light cup and the plug are fixedly arranged at the two ends of the light cap respectively. An LED light source is fixedly arranged at the bottom of the light cup and emits light towards an opening of the light cup in the axial direction of the spotlight. A control drive board used for offering a constant current is further arranged in the light cap. A control circuit of the control drive board is a mini-type semiconductor type constant current circuit. The two ends of the control drive board are electrically connected with the plug and the LED light source respectively. Multiple layers of heat dissipation covers are further sandwiched between the light cup and the light cap. The heat dissipation covers extend in the direction of the opening of the light cup and the extending length is gradually reduced layer by layer from inside to outside. The heat dissipation covers are in a radial shape. The LED spotlight is small in emitted heat, good in heat dissipation effect and long in service life.
Description
Technical field
The present invention relates to a kind of LED shot-light, relate in particular to a kind of radiator structure of LED shot-light.
Background technology
Shot-light, is a kind of directionality that has, and the light fixture of height optically focused, and light efficiency, over against jobbie, can be emphasized the texture of object, such as for adoring cabinet, and mirror cabinet or video wall; Can be used for again illuminating and lighting, heighten atmosphere.
Conventional MR11, the core of MR16 shot-light are to use the source that Halogen lamp LED is principal light source, so can produce a large amount of heats, and the Lamp cup of shot-light itself is glass material, although glass can bear larger heat, do not need radiating treatment means, but a large amount of heat energy is but the aging main cause of the MR shot-light lost of life.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provides that a kind of caloric value is few, the LED shot-light of good heat dissipation effect, long service life.
The present invention realizes by following technical scheme:
A kind of LED shot-light, the Lamp cup and the plug that comprise lamp holder and be fixedly arranged on respectively lamp holder two ends, described Lamp cup bottom is installed with LED light source, described LED light source is luminous towards Lamp cup opening direction on shot-light is axial, in described lamp holder, be also provided with for the control drive plate of constant current is provided, the control circuit of described control drive plate is micro semiconductor formula constant-current circuit, described control drive plate two ends are electrically connected to plug and LED light source respectively, between described Lamp cup and lamp holder, be also folded with some layers of heat dissipating housing, described heat dissipating housing extends and successively reduces from inside to outside the length of extending towards the opening direction of Lamp cup, between described some layers of heat dissipating housing, be divergent shape.
Further, on described heat dissipating housing, be provided with some air vents.
Further, the air vent on described some layers of heat dissipating housing staggers mutually.
Further, the bottom of described heat dissipating housing is provided with to hold and is communicated with the wire guide that LED light source and the wire of controlling drive plate pass through.
Further, described heat dissipating housing is multi-disc petal-shaped.
The invention has the beneficial effects as follows: compared with prior art, the present invention controls drive plate by employing makes On current constant, reduce the caloric value of LED light source, simultaneously, some layers of heat dissipating housing are set between Lamp cup and lamp holder, the caloric value of LED shot-light is reduced, extended service life of LED light source, the shot-light that is particularly suitable for the series such as MR11, MR16 is used.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, wherein:
Fig. 1 is LED shot-light schematic diagram of the present invention.
The specific embodiment
LED shot-light 1 as shown in Figure 1, the Lamp cup 4 and the plug 3 that comprise lamp holder 2 and be fixedly arranged on respectively lamp holder 2 two ends, the bottom of Lamp cup 4 is installed with LED light source, LED light source LED shot-light 1 axially on luminous towards Lamp cup 4 opening directions.
Between Lamp cup 4 and lamp holder 2, be folded with some layers of heat dissipating housing 5, heat dissipating housing 5 adopts aluminum material to make, in the present embodiment, adopt two-layer heat dissipating housing 5, be respectively the first heat dissipating housing 51 and the second heat dissipating housing 52, the first heat dissipating housing 51, the second heat dissipating housing 52 are folded between lamp holder 2 and Lamp cup 4 and extend along the opening direction of Lamp cup 4, thereby the heat that LED light source is sent is delivered on the first heat dissipating housing 51 and the second heat dissipating housing 52 and outwards carries out heat exchange.The length that the first heat dissipating housing 51 extends should be greater than the length that the second heat dissipating housing 52 extends, and is conducive to improve radiating effect, and the area that the first heat dissipating housing 51, the second heat dissipating housing 52 are directly contacted with extraneous air is larger.Meanwhile, by the Lamp cup 4 of innermost layer, started, to outermost the second heat dissipating housing 52, successively to reduce development length, make the moulded as flower in full bloom of LED shot-light 1, thereby can make handsome in appearance and can improve radiating effect.For making LED shot-light 1 moulded more attractive in appearance, the first heat dissipating housing 51, the second heat dissipating housing 52 can also be imitated the petal-shaped that various types of flowers are arranged to multiple-piece.For making radiating effect better, can on the first heat dissipating housing 51 and/or the second heat dissipating housing 52, some air vents 50 be set, while being provided with air vent 50 on the first heat dissipating housing 51, the second heat dissipating housing 52, need guarantee that the air vent 50 on the first heat dissipating housing 51, the second heat dissipating housing 52 staggers mutually, thereby can accelerate extraneous air flowing between the second heat dissipating housing 52 and the first heat dissipating housing 51, the first heat dissipating housing 51 and Lamp cup 4, the heat on the first heat dissipating housing 51, the second heat dissipating housing 52 and Lamp cup 4 is taken away in time.
Above embodiment is only not limited in order to technical scheme of the present invention to be described, does not allly depart from any modification of spirit and scope of the invention or is equal to replacement, and it all should be encompassed in the scope of technical solution of the present invention.
