Description

The radiator structure of light-emittingdiode
Technical field
The utility model relates to a kind of radiator structure, especially a kind of radiator structure that is used for light-emittingdiode.
Background technology
In realizing the utility model embodiment process, there are the following problems at least in the prior art:
Because the appearance of ultra-high brightness LED (light-emittingdiode), reach reaching its maturity of white light LEDs technology, be applied to products such as desk lamp, projecting lamp and grow up gradually, the LED illumination epoch have arrived, even future can replace present incandescent osram lamp, become the main light source of room lighting.Disclose a kind of light-emittingdiode (Light Emitting Diode in the prior art; LED) structure comprises at least: a substrate; The semiconductor epitaxial structure, at least comprise a n type semiconductor layer, an active layers and a p type semiconductor layer, wherein this n type semiconductor layer covers this substrate, be formed with a plurality of thrusts on this n type semiconductor layer part surface, and be provided with a passage between per two those adjacent thrusts, and this active layers and this p type semiconductor layer stack in regular turn on those thrusts; One N type electrode layer is attached on this n type semiconductor layer and is arranged in this passage; And a plurality of P type electrodes, be positioned on this p type semiconductor layer.
Yet, because LED brightness increases gradually, make the LED luminescence process, because of electric energy converts the conversion efficiency difference of luminous energy to so that often supervenes a large amount of heats, immediately this heat is derived if fail, LED is shortened service life, also may cause the nearby electron element to damage, severe patient even may cause fire; Therefore, how the heat of LED generation is in time derived, a big problem of endeavouring to study for relevant dealer.
The utility model content
The problem that the utility model embodiment will solve is that light-emittingdiode heat that produces in luminescence process is effectively derived.
For achieving the above object, the utility model embodiment proposes a kind of radiator structure of light-emittingdiode on the one hand, comprising: a circuit substrate, and this circuit substrate is installed with at least one light-emittingdiode, and layout has the circuit that this light-emittingdiode required electric power is provided on it; One heat conducting element, an end of this heat conducting element touches this circuit substrate; One heat abstractor, the other end of this heat abstractor and this heat conducting element touches.
The technical scheme of the utility model embodiment has the following advantages: good heat conductivity, safety coefficient height, the long service life of diode.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail:
As Fig. 1 and shown in Figure 2, it is STRUCTURE DECOMPOSITION figure and the stereoscopic schematic diagram of the utility model embodiment one.The utility model provides a kind of radiator structure of light-emittingdiode, includes:
One circuit substrate 1 is laid with the circuit (not shown) on this circuit substrate 1, and at least one light-emittingdiode 2 is set, and in the present embodiment, what this circuit substrate 1 was adopted is to connect to establish a pedestal 10, and this circuit substrate 1 forms an accommodation space 12 with this pedestal 10;
One heat conducting element 3, these heat conducting element 3 at least one ends have touched this circuit substrate 1, and in the present embodiment, this heat conducting element 3 is a heat pipe, and this heat pipe one end is coated in this accommodation space 12; And
One heat abstractor 4, this heat abstractor 4 is provided with that plural number is spaced and touched fin 40 with this heat conducting element 3, wherein this heat conducting element 3 wears fin 40, and in 40 a plurality of gaps of formation of this fin, be used to provide air-flow heat that this heat conducting element 3 conducts is exported to extraneous 42, in the present embodiment, this heat abstractor 4 also can comprise a fan 44, and the wind of this fan 44 directly flows to and is parallel to this gap 42.
As shown in Figure 3, Figure 4, it is STRUCTURE DECOMPOSITION figure and the stereoscopic schematic diagram of the utility model embodiment two.In the present embodiment, these light-emittingdiode 2 radiator structures can be placed in the housing 5, are used for holding circuit substrate 1, heat conducting element 3 and heat abstractor 4, and then isolate extraneous moisture, rainwater and dirt.
As Fig. 5, shown in Figure 6, STRUCTURE DECOMPOSITION figure and stereoscopic schematic diagram that it looses for the utility model embodiment.In the present embodiment, circuit substrate 1 and pedestal 10 are arranged at the first surface 50 of housing 5, and this heat abstractor 4 is arranged at the second surface 52 of this housing 5, and are provided with one in 50,52 on first, second surface this open-work that heat conducting element 3 wears 54 is provided.Therefore, present embodiment not only can be isolated extraneous moisture, rainwater and dirt by this housing 5, also this heat abstractor 4 can be arranged on open space outerpace, improves the heat dissipation of this heat abstractor 4 whereby.
In sum, because the utility model utilization heat conducting element 3 fast is directed at the external world because of electric energy converts heat that luminous energy produces to light-emittingdiode 2 with heat abstractor 4 in luminescence process, so can effectively avoid light-emittingdiode short, defectives such as the nearby electron element is easily damaged, easy initiation fire in 2 service lifes in the prior art; In addition, because the protection of housing 5 can also be isolated extraneous moisture, rainwater and dirt.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
