Description

A kind of LED Down lamp

Technical field

The utility model relates to LED field of light fittings, particularly a kind of LED Down lamp.

Background technology

LED Down lamp, because of advantages such as it is energy-conservation, luminous efficiency is high, long service life, is widely used.LED Down lamp generally comprises cover, be connected in the lamp body of cover lower end, be located at light transmission piece in cover, be located at the LED light source structure in lamp body, the drive unit being electrically connected with LED light source structure, also comprises radiator.In existing structure, in order to reach good radiating effect, radiator is generally arranged on the bottom of lamp body, between radiator and lamp body bottom, is connected and fixed by bonding agent or screw.Such structure, radiator is outside exposed, once bonding agent or screw get loose, just easily cause whole radiator to split away off, affected radiating effect, and then affected the service life of LED Down lamp, in addition, radiator is outside exposed, has affected the specious of whole lamp.

Therefore, how to realize a kind of specious, good heat dissipation effect, sound construction rationally, the LED Down lamp of long service life is technical problem urgently to be resolved hurrily in the industry.

Summary of the invention

Main purpose of the present utility model is to provide a kind of LED Down lamp, be intended to realize a kind of specious, good heat dissipation effect, sound construction rationally, the LED Down lamp of long service life.

The utility model proposes a kind of LED Down lamp, comprise cover, be connected in cover lower end lamp body, be located at light transmission piece in cover, be located at the LED light source structure in lamp body, the drive unit being electrically connected with LED light source structure, also comprise radiator, lamp body lower end is extended adaptive with radiator down and can be embedded the installation cavity into radiator, the sidewall of installation cavity is set to the engraved structure that can ventilate, and radiator is from top to bottom embedded interior into installation cavity and is fixed by the mode of being spirally connected; Radiator is the circular ring structure of hollow, the lateral wall of circular ring structure is longitudinally laid with the radiating fin of inclination, circular ring structure madial wall is provided with some screw hole columns, installation cavity bottom is provided with screw in position corresponding to screw hole column, is screwed into and in screw, screw hole column, radiator is spirally connected to be fixed in installation cavity by screw.

Preferably, cover and the lamp body structure that is formed in one.

Preferably, cover and lamp body are made up of metal or plastics.

Preferably, radiator is made up of heat-conducting metal.

Preferably, LED light source structure comprises circuit board, is laid in circuit onboard led lamp pearl.

Preferably, also comprise be located at cover both sides LED Down lamp can be mounted on to the fixing jump ring taken of sky.

The radiator of the utility model LED Down lamp is installed in the installation cavity of lamp body inside, appearance is succinctly attractive in appearance, even and for a long time use, radiator also may get loose situation about dropping hardly, sound construction is reasonable, has guaranteed radiating effect and the service life of whole lamp.Meanwhile, the sidewall of installation cavity is set to the engraved structure ventilating, and has ensured the radiating efficiency of radiator.The utility model really realized a kind of specious, good heat dissipation effect, sound construction rationally, the LED Down lamp of long service life.

Brief description of the drawings

Fig. 1 is one of perspective view of an embodiment of a kind of LED Down lamp of the utility model;

Fig. 2 be an embodiment of a kind of LED Down lamp of the utility model perspective view two.

Realization, functional characteristics and the advantage of the utility model object, in connection with embodiment, are described further with reference to accompanying drawing.

Detailed description of the invention

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Referring to figs. 1 through Fig. 2, one embodiment of a kind of LED Down lamp of the present utility model is proposed, comprise cover 100, be connected in cover 100 lower ends lamp body 200, be located at light transmission piece 300 in cover 100, be located at the LED light source structure in lamp body 200, the drive unit being electrically connected with LED light source structure, also comprise radiator 400, be located at cover 100 both sides LED Down lamp can be mounted on to the fixing jump ring 500 that sky is taken.
