Description
Technical field
The utility model relates to a kind of radiating high-power LED shot-light.
Background technology
Along with the continuous development of LED technology and popularizing in a large number of application technology, the LED light fixture of environmental type is used in various aspects in the life by people more and more, the tradition shot-light adopts Halogen lamp LED more, luminous efficiency is lower, relatively power consumption, illuminated environment temperature rises, service life is short, and the LED shot-light with it in energy savings, long service life, tunable optical, frequent switch, color is abundant, the advantage of aspects such as caloric value is low replaces traditional shot-light just gradually, the MR16LED shot-light is the low-power light fixture of band multiaspect reflector, lower powered LED shot-light caloric value is fewer, so need not to consider heat dissipation problem, but simultaneously, the brightness of lower powered LED shot-light is limited, the LED shot-light is if obtain enough brightness, will improve the power of LED shot-light, and along with the increase of power, its caloric value is also along with increase, at this time just must consider the problem of heat radiation, otherwise influence LED shot-light job stability and service life easily, this also is that the LED light fixture does not temporarily replace one of reason of conventional lamp comprehensively, at present, existing LED shot-light is in order to overcome heat dissipation problem, many radiators and heat dissipating method are arranged, but complex structure, the cost height, or do not reach good heat-radiation effect, badly influence the all-round popularization and the use of LED shot-light.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low, the radiating high-power LED shot-light of good heat dissipation effect, long service life.
The technical scheme that the utility model adopted is: the utility model comprises insulating lamp holder, radiator, metal substrate, led light source, constant-current driving power supply, described insulating lamp holder is fixedlyed connected with the tail end of described radiator, described metal substrate is installed on the end face of described radiator front end, described led light source is fixedly installed on the front of described metal substrate radius outwardly, the outer wall of described radiator is provided with a plurality of radiating fins, described constant-current driving power supply is positioned at the inside of described radiator, and is connected with two power supply contact lines on the described insulating lamp holder with described led light source respectively.
Described led light source comprises at least one led chip.
Described insulating lamp holder is provided with several air vents.
Described metal substrate scribbles heat-conducting glue with the position that described radiator contacts.
Described radiating high-power LED shot-light also comprises lampshade, and described lampshade is positioned at the front end of described radiator and is threaded with described radiator.
The beneficial effects of the utility model are: because the utility model comprises insulating lamp holder, radiator, metal substrate, led light source, constant-current driving power supply, described insulating lamp holder is fixedlyed connected with the tail end of described radiator, described metal substrate is installed on the end face of described radiator front end, described led light source is fixedly installed on the front of described metal substrate radius outwardly, the outer wall of described radiator is provided with a plurality of radiating fins, described constant-current driving power supply is positioned at the inside of described radiator, and be connected with two power supply contact lines on the described insulating lamp holder with described led light source respectively, what fix described led light source is metal substrate, described metal substrate directly contacts with described radiator, simple in structure, cost is low, and the heat that described led light source produced passes to described radiator through described metal substrate, be dispersed in the air by described a plurality of radiating fins, so the utility model is simple in structure, cost is low, good heat dissipation effect, long service life.
