Summary of the invention
Technical problem to be solved by this invention is that a kind of LED shot-light that can use quartz container will be provided,
In order to solve the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of LED shot-light, comprise emitting led, led drive circuit plate and shot-light shell, described shot-light shell is a quartz envelope, be set with the heat dissipation metal cover in it, emitting led being fixedly set in the heat dissipating housing, the led drive circuit plate is arranged at the lamp housing root at interval between heat dissipating housing and the lamp housing, and the led drive circuit plate is electrically connected with emitting led by lead.
Described emitting led by high temperature heat-conducting glue or heat-conducting silicone grease fixed bonding in heat dissipation metal cover bottom.
In order to be that the radiating efficiency of heat dissipating housing is higher at the back side of described heat dissipation metal cover, promptly the one side towards the shot-light shell preferably is provided with radiating groove.
Described emitting led front end preferably is provided with lens.Its light just can reach specific optically focused requirement like this.
The front opening place of heat dissipation metal cover also is set with the end cap of a fixed lens, and lens are arranged at emitting led front end surely by the pressure build-in of end cap.
Bottom in described heat dissipation metal cover also is set with one can be with the both positive and negative polarity lead-out wire and the emitting led aluminium base that is electrically connected of led drive circuit plate, emitting ledly is fixedly set on the aluminium base, is fixedly set in the heat dissipating housing by aluminium base.
Described aluminium base is preferably by high temperature heat-conducting glue or the bottom of heat-conducting silicone grease fixed bonding in the heat dissipation metal cover.
LED shot-light for higher-wattage, at the back side of described peviform heat dissipation metal cover, promptly preferably scribble the heat radiation coating layer towards the one side surface of shot-light shell, described heat radiation coating is to be coated in heating electrical equipment or fin surface to play the coating of radiating and cooling effect, thereby reduces body surface and internal temperature apace.
LED shot-light of the present invention has adopted the structure that is embedded peviform heat dissipation metal cover in unique lamp housing, the high heat that produces when being fixedly set in the emitting led work of heat dissipating housing bottom so just can be by the tight heat dissipation metal cover of contact connection, the conduction in time of its high heat is distributed, this structure make LED shot-light structure more rationally, safer, also more attractive in appearance; And for the halogen spot light of existing use quartz envelope, can on the basis of using original lamp housing, change the LED shot-light more energy-conservation, that luminous efficiency is higher, in the lamp housing of original halogen spot light, install heat dissipating housing, emitting led and lens etc., make the energy-conservation upgrading of the quartz halogen lamp of being used widely become possibility according to structure of the present invention.
The use of high temperature heat-conducting glue (such as Japanese Sekisui #5760) or heat-conducting silicone grease can make to link together more securely between the parts, can increase the contact area of emitting led, aluminium base and heat dissipating housing again, makes heat radiation more smooth and easy.
