Abstract
The utility model discloses a light-emitting diode (LED) lamp with the radiation function. The LED lamp comprises an aluminum alloy radiation lamp body, an LED light source module is positioned in the aluminum alloy radiation lamp body, a secondary optical dimming element is arranged on the aluminum alloy radiation lamp body on the outer side of the LED light source module, curve radiation fins are distributed at the back of the aluminum alloy radiation lamp, and the LED light source module is formed by an aluminum substrate and LED lamps distributed on the aluminum substrate. Due to the facts that the curve radiation fins are arranged at the back of the radiation substrate, and the outer surfaces of the radiation fins are in small wave shapes or small sawtooth shapes, radiation area of the radiation fins are greatly increased in equal space limit, heat generated by lighting of the LED can be well transferred to the air to achieve the purpose of quick radiation. Simultaneously, service life is prolonged and lighting efficiency is improved.
Description
Technical field
The utility model relates to the LED field, relates in particular to a kind of LED lamp with heat sinking function.
Background technology
Existing light emitting diode all is to be fixed in body with crystal, and metal heat pillow is established in the bottom side of body, and light emitting diode is rested the head on the radiator that reclines with heat during use, and radiator for example is an aluminium base.This device only is to recline merely to press set because of its no fixed structure, heat pillow, and its radiating effect is bad.
Especially recently the power of light emitting diode is high-power towards adding gradually; Or be combined into a most crystal series and parallel and add high-power direction and develop; Tradition light emitting diode, especially large-power light-emitting diodes only lean on radiator with heat pillow card merely, and its heat-sinking capability and heat transfer rate are all comparatively slow, and need carry out hot driving a period of time; This will cause large-power light-emitting diodes to form hot environment work in a period of time; This tends to cause the large-power light-emitting diodes illumination brightness of failing fast, also can cause reduce service life, has limited the development of LED lighting; How to increase LED power and increase the heat conduction and heat radiation ability, then for the dealer makes great efforts in a hurry the primary work of solution.
Also can't effectively get rid of heat, the restriction power of LED own and form set power in view of the heat radiation of habitual illuminating lamp use LED, must improve the LED overall structure, making to increase the power use.
Summary of the invention
The purpose of the utility model is to provide a kind of and has rapid heat dissipation, long service life, increases the LED lamp of crystal whole lighting efficiency simultaneously.
The purpose of the utility model realizes through following technical scheme.
A kind of LED lamp with heat sinking function; Comprise aluminium alloy heat radiation lamp body; In aluminium alloy heat radiation lamp body, be provided with the led light source module; On the aluminium alloy heat radiation lamp body in the led light source module outside, be provided with the secondary optics Light modulating device, the described aluminium alloy heat radiation lamp body back side is distributed with curved heat-dissipating fin, and described led light source module is made up of aluminium base and the LED lamp that is distributed on the aluminium base.
Preferably, described heat-dissipating fin outer surface is minor undulations or spiculation.
Preferably, described secondary optics Light modulating device is the even light shield of secondary optics, the overall structure that described aluminium alloy heat radiation lamp body and heat-dissipating fin are formed in one.
The utility model embodiment compared with prior art; Beneficial effect is: the LED lamp with heat sinking function that the utility model provides is through being provided with curved heat-dissipating fin at the heat-radiating substrate back side; And this heat-dissipating fin outer surface is minor undulations or spiculation, and under equal limited space, the heat-dissipating fin of the utility model can increase area of dissipation greatly; The heat that is produced when making LED luminous transmits heat radiation in the ambient air preferably; To reach the quick heat radiating purpose, prolonged service life simultaneously, improved luminous efficiency.
Description of drawings
Fig. 1 is the utility model LED modulated structure figure.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1; The utlity model has the LED lamp of heat sinking function, comprise aluminium alloy heat radiation lamp body 1, in aluminium alloy heat radiation lamp body 1, be provided with led light source module 2; In the present embodiment, led light source module 2 is made up of aluminium base 2a and a plurality of LED lamp 2b that are distributed on the aluminium base 2a; On the aluminium alloy heat radiation lamp body 1 in led light source module 2 outsides, be provided with secondary optics Light modulating device 3; In the present embodiment; Secondary optics Light modulating device 3 is evenly distributed with curved heat-dissipating fin 4 for the even light shield of secondary optics (also can adopt diffuser to combine even mating plate of secondary optics or diffuser to combine the structure of the even light body of optically focused) at aluminium alloy heat radiation lamp body 1 back side, and curved surface can be S shape or waveform; And these heat-dissipating fin 4 outer surfaces are minor undulations or spiculation; Like this can be in equal heat-dissipating space, the area of dissipation than the common about twice of linear pattern heat-dissipating fin raising significantly improves radiating effect.
In the present embodiment, heat-dissipating fin 4 is a S shape, and each heat-dissipating fin 4 outer surface is minor undulations; Further, easy for what install and process, dispel the heat lamp body l and heat-dissipating fin 4 of aluminium alloy processed integrated overall structure, make install and processing all very convenient.
The LED lamp with heat sinking function that the utility model provides is through being provided with curved heat-dissipating fin at the heat-radiating substrate back side; And this heat-dissipating fin outer surface is minor undulations or spiculation, and under equal limited space, the heat-dissipating fin of the utility model can increase area of dissipation greatly; The heat that is produced when making LED luminous transmits heat radiation in the ambient air preferably; To reach the quick heat radiating purpose, prolonged service life simultaneously, improved luminous efficiency.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
