The high-power LED (Light-Emitting Diode) heat-radiating device provided by the utility model can solve the drawbacks that due to bad heat radiation of the LED lamp, the light-emitting efficiency is affected, and the service life is shortened.
Description
Technical field
The utility model belongs to the energy-conserving and environment-protective technical field, specifically just relates to a kind of great power LED heat sink for lamp.
Background technology
Along with the fast development of economic life, energy-output ratio is more and more huger, and the energy-conserving and environment-protective technology more and more receives people's attention, wherein; The electricity-saving lamp technology is development technical field very fast, and the electricity-saving lamp of various kinds emerges in an endless stream, in recent years, and along with the fast development of science and technology; The illuminating LED lamp is at cost, and aspect of performance has been obtained significant progress, compares with traditional lighting apparatus, and the life-span of modern LED lighting is long; Start-up time is short, sound construction, and energy-efficient performance is more superior; The production of led light source simultaneously can realize mercuryless, can not pollute environment, and have preferable energy-efficient performance.
What conventional light source adopted is high-pressure mercury lamp or high-pressure sodium lamp, and the response time of this type high-voltage gas discharging light reaches a few minutes even tens minutes, and energy utilization rate is lower, and energy consumption is very big.Along with low power consuming, response LED lighting engineering fast, that the life-span is long reach its maturity, make normal lighting use energy-saving lamp to become the trend in a kind of future.But the LED lamp of developing at present, light source all adopts the series-parallel mode of a plurality of low-power LEDs to form array, and the heating of entire equipment is bigger.And LED is to temperature sensitivity very, dispels the heat badly to bring that the too high LED of the causing luminous efficiency of temperature reduces, the lost of life.
The utility model content
The utility model technical problem to be solved provides a kind of great power LED heat sink for lamp that is used for, and can solve the LED lamp influences luminous efficiency, causes the drawback of the lost of life because of the heat dispersion difference.
Technical scheme
In order to solve above-mentioned technical barrier; The utility model designs a kind of great power LED heat sink for lamp; Comprise heat radiator, aluminium base, LED lamp, heat-conducting plastic base plate, it is characterized in that said aluminium base is embedded in the heat-conducting plastic base plate; The LED lamp is fixed in the aluminium base installing hole, and heat radiator is contained on the LED lamp.
Have opening on the said heat-conducting plastic base plate.
Said heat radiator profile is a fin shapes.
Beneficial effect
LED lamp heat is mainly with conduction, radiation, convection current transmission, LED lamp heating power, and heat is delivered to aluminium base; Be delivered to again on heat-conducting plastic base plate and the graphite through aluminium base; Heat radiator between LED lamp and the lamp has certain distance, on the heat-conducting plastic base plate, stamps through hole, and heat is flowed out through convection current; Accelerate radiating effect, the luminous flux of increase LED and life-span etc.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is done further elaboration.
Shown in accompanying drawing 1, a kind of great power LED heat sink for lamp comprises heat radiator 1, aluminium base 2, LED lamp 3, heat-conducting plastic base plate 4; Wherein, Said aluminium base 2 is embedded in the heat-conducting plastic base plate 4, and LED lamp 3 is fixed in aluminium base 2 installing holes, and heat radiator 1 is contained on the LED lamp 3.
Have opening on the said heat-conducting plastic base plate 4.
Said heat radiator 1 profile is a fin shapes.
