Description
Technical field
The present invention relates to a kind of heat abstractor of LED lamp and use the LED light fixture of its heat abstractor.
Background technology
LED, be light emitting diode, because long in energy-conservation, life-span in recent years, no stroboscopic, brightness is strong etc., and there is development at full speed the key technical indexes aspect, be widely used in multiple place occasions such as Landscape Lighting, large screen display, and will have entered the general lighting field on a large scale.Along with the increase of LED power, heat production is bright too much, and bad if heat dissipation problem solves, heat concentrates in the small-sized chip, then can quicken the aging of device, reduction of service life, even cause chip to burn.At present, though various radiators and heat dissipating method are arranged, radiating effect is not very desirable.Therefore the popularization and the use of LED lamp have been badly influenced.
Summary of the invention
The heat abstractor of LED lamp of the present invention technical problem to be solved is to overcome the deficiencies in the prior art, and the heat abstractor of the LED lamp of a kind of life-span length, good heat dissipation effect is provided.
In addition, the present invention provides also that a kind of light is concentrated, the LED light fixture of the heat abstractor of the use LED lamp of good uniformity.
The technical scheme that heat abstractor adopted of LED lamp of the present invention is: the heat abstractor of LED lamp of the present invention comprises radiator; led light source; the lamp housing assembly; described led light source and described radiator are connected and fixed and are arranged on described lamp housing component internal; described led light source is one or many led chips; described radiator is made up of the polylith fin; described fin is emitting shape along the axle center of described radiator and is spaced circlewise; described lamp housing assembly is provided with louvre I and louvre II, and described louvre I and described louvre II lay respectively at described radiator upper and lower.
Described lamp housing assembly comprises lamp body, loam cake, bottom, and described bottom is fixedly installed on described lamp body bottom, and the top of described loam cake and lamp body is for being threaded.
The technical scheme that LED light fixture of the present invention is adopted is: LED light fixture of the present invention also comprises reflector, transmissive mirror, described led light source is fixedly installed near the focus of described reflector, described transmissive mirror is arranged on described reflector top, and the light that described led light source sends is through reflector reflection process transmissive mirror ejaculation again.
Described transmissive mirror is simple glass or convex lens.
The invention has the beneficial effects as follows: because radiator of the present invention is made up of the polylith fin, the contact area of every described fin and air is big, so described radiator can be dispersed in the described lamp housing component internal air by the more effective heat that described led light source is sent, because described lamp housing assembly is provided with louvre, the position of described louvre is in the position, upper and lower of described radiator respectively, when heat that every described fin sends described led light source is dispersed in the described radiator ambient air of described lamp housing component internal, when the described radiator ambient air expanded by heating of the described lamp housing component internal described louvre by described radiator top is set to described casing assembly flows outside, cool exterior air flows into the inner convection effect that produces of casing assembly by the described louvre that is arranged on described radiator bottom, convection current can better distribute the heat of described lamp housing component internal, described radiator is fixed on by described fin and effectively conducts heat on the described lamp housing assembly on the described lamp housing assembly, outwards dispel the heat by described lamp housing assembly, thereby effectively the heat that LED produced is dispersed in the external environment condition timely, can led chip not be burnt because of too high causing of led light source temperature.So good heat dissipation effect of the present invention, the long service life of led chip.
Because LED light fixture of the present invention is provided with reflector and transmissive mirror, reflector has the effect of concentrated light, and transmissive mirror is that simple glass then can make light even, when transmissive mirror is that convex lens then can collected light, therefore LED lamp of the present invention can send more concentrated, the light of good uniformity.

The specific embodiment
Embodiment one:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, LED light fixture of the present invention comprises radiator 1, led light source 2, lamp housing assembly 3, reflector 4, transmissive mirror 5, described led light source 2 is a led chip, described radiator 1 is made up of polylith fin 11, be separated with the gap of certain space between every described fin 11, described led light source 2 usefulness screws are fixed on described radiator 1 top, three fin of described radiator 1 insert the inside grooves of described lamp housing assembly 3 inside, described lamp housing assembly 3 usefulness metallic aluminiums are made, louvre I 9 and louvre II 10 are arranged on the upper and lower that lays respectively at described radiator 1 on the described lamp housing assembly 3, described lamp housing assembly 3 comprises lamp body 8, loam cake 6, bottom 7, described bottom 7 is provided with louvre II 10 and is fixedly installed on described lamp body 8 bottoms, the top of described loam cake 6 and lamp body 8 is for being threaded, and transmissive mirror 5 can be made with a simple glass and be installed between lamp body 8 and the loam cake 6.Power line connects led light source 2 and radiator 1, when connecting power supply, led light source 2 and radiator 1 are started working, the light that sends when led light source 2 reflects after simple glass is made transmissive mirror 5 ejaculations through reflector 4, led light source 2 produces a large amount of light and heat amounts when work, the heat that radiator 1 sends led light source 2 is taken away and is had major part to pass in the air of lamp housing assembly 3 inside, along with lamp housing assembly 3 Inside Air Temperatures slowly raise, because described lamp housing assembly 3 is provided with louvre I 9 and louvre II 10, described louvre I 9 and louvre II 10 can be the through hole of a plurality of annulars or other shape, so lamp housing assembly 3 temperature inside can pass by cross-ventilation, also there is the part heat to pass to lamp housing assembly 3 and propagates in the extraneous air again by radiator 1.Therefore the heat abstractor of LED lamp of the present invention mainly passes the heat that led light source 2 sends by the cross-ventilation principle, thereby reaches more effective heat radiation, has improved the service life of led light source 2, and the light that sends is concentrated, good uniformity.So can making Down lamp, LED light fixture of the present invention is used for indoor general lighting field.
Embodiment two:
As shown in Figure 5, the difference of present embodiment and embodiment one is: LED light fixture of the present invention is the transmissive mirror made from convex lens 5, can collected light, in described lamp housing assembly 3 arranged outside support 12 is arranged, and can regulate irradiating angle.Therefore can make shot-light, be used for indoor product irradiation.
All the other features are with embodiment one.
