Description
Technical field
The utility model relates to a kind of LED shot-light, particularly a kind of great power LED shot-light.
Background technology
A few days ago, LED (light emitting diode) technical development is rapid, and the ratio that led light source occupies on illumination market is increasing.The appearance of the great power LED product of 80lm/W makes the trend of LED replacement tungsten filament lamp for general service more and more obvious.
Than traditional light source, great power LED is as lighting bulb, and in particular for shot-light, its advantage is low-voltage power supply, and single-chip LED operating voltage is generally at the 3-4 volt, and is far below the operating voltage of common bulb light source, safe and reliable; Simple in structure, belong to solid light source, to compared with tungsten light source, have shock-resistantly, vibration resistance is difficult for advantages such as fragmentation; LED is a cold light source, and controllability is good, and the response time is fast, frequently light on and off repeatedly, and traditional tungsten light source is if frequent light on and off must make the life-span die-off owing to expanding with heat and contract with cold fast; The long service life of led light source reached more than 50,000 hours, was 4 to 5 times of conventional light source such as incandescent lamp, avoided frequent maintenance and replacing; LED is energy-efficient, and its luminescent spectrum nearly all concentrates on visible light frequency band, and illuminating effect is more energy-conservation more than 50% than conventional light source; The led light source environmental protection, no harmful element and heavy metal, pollution-free in the production process.
A few days ago, its structure of LED shot-light generally comprises three parts on the market: front end is lens, be used to focus on the light of LED outgoing, mid portion is a metal lamp body, be used to install led chip and heat radiation, tail end is the insulator of a hollow, and in order to hold drive circuit, its rear end is provided with the inserted link that cooperates with lamp socket.
Wherein, in the metalized lamp body structure, the LED packaged chip is installed on earlier on the wiring board of a Metal Substrate, after heat-conducting glue is coated in this wiring board bottom, is fastened on the lamp body with screw again.Wiring board is used to install packaged chip and lead-in wire, plays conductive force simultaneously.
Present LED shot-light generally adopts the high-power LED chip, and caloric value is bigger during its work, and the heat that produces as can not be in time with chip operation the time sheds, and then can influence the operate as normal and the service life of shot-light.And the LED shot-light of said structure, the heat that its led chip produces needs the intermediate transfer by wiring board just can be transferred on the metal lamp body as radiator.Usually on the outer surface of metal lamp body, offer some span type radiating parts, to improve radiating effect.
Because people need pinch the metal lamp body with finger and be rotated, though the voltage of LED shot-light is very low when the LED shot-light is installed, belong to safe range, but metal lamp body after all, people have a kind of sensation of getting an electric shock be afraid of, make people have psychological burden when the LED shot-light is installed.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of great power LED shot-light, and this great power LED shot-light can be eliminated the psychological condition that people get an electric shock, and can improve radiating effect simultaneously.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of great power LED shot-light, comprise a metal lamp body, high-power LED light source and be positioned at the lens of metal lamp body front end and the lamp holder that is positioned at metal lamp body tail end, it is characterized in that, also comprise a lamp body cover of being made by insulating materials, the shape of the shape of described lamp body cover and metal lamp body adapts and is enclosed within on the outer surface of described metal lamp body.
Be provided with axial straight striated structure down at the outer surface of metal lamp body, the described lamp body cover inner surface and the outer surface of straight striated structure are down fitted and and the two straight ventilating ducts of the straight lower recess formation upper and lower opening between the striped down.
Described lamp body cover is a transparent configuration, and is coated with layer of metal coating on the inner surface of described lamp body cover, makes whole lamp body cover have a kind of effect of metal-like.
Lens of the present utility model can be selected the sheet glass of appropriateness atomizing shape or the optical mirror slip of bright cleaning sheet glass of full impregnated or epoch luminous intensity distribution prism structure according to different instructions for uses.
Adopt the following advantage that the utlity model has of said structure:
1, because at the external lamp body cover with insulating effect that is with of metalized lamp, people are when installing this great power LED shot-light, only need hold the lamp body cover and get final product, not touch the metal lamp body, eliminate the electric shock feared state of mind of people when this great power LED shot-light is installed and do not need to catch with hand.
2, because the straight lower recess of the inner surface of lamp body cover and metalized lamp external surface forms the ventilating duct of upper and lower opening, that is to say and on the outer surface of metal lamp body, formed many ventilating ducts, the heat that distributed of metalized lamp surface can distribute soon like this, good ventilation is simultaneously also played cooling effect to the metalized lamp surface, and radiating effect is further improved.
3, the lamp body cover is a transparent configuration, and the inner surface at the lamp body cover plates layer of metal coating simultaneously, makes the lamp body cover that is made of plastics have a kind of effect of metal-like.
