Detailed description of the invention
Further set forth advantage of the present utility model below with reference to specific embodiment and accompanying drawing.
Be illustrated in figure 1 the sectional view of the utility model LED shot-light one embodiment, it comprises, accommodation section 11, at least one first heat radiation conduit 12, at least one heat dissipation channel 13, housing 14 and at least one the second heat radiation conduit 15.LED shot-light 10 middle parts are located in accommodation section 11, for light-emitting device (such as LED light source or with the LED light source of reflector) is set.Accommodation section 11 can an end opening, and LED light source is gone out irradiation by this opening or is enclosed in accommodation section 11 by a light transmission device.Heat dissipation channel 13 is located between accommodation section 11 and housing 14, for realizing air and the 10 outer air convection current of LED shot-light of LED shot-light 10 inner housings 14.Heat dissipation channel 13 can have multiple and arrange around accommodation section 11, also single.This passage is by the spatial composing between accommodation section 11 and housing 14, make the air (i.e. air in heat dissipation channel 13) of 11 peripheries, accommodation section to be effectively lowered temperature by cross-ventilation, the temperature in accommodation section 11 also can be lowered whereby.The first heat radiation conduit 12 is positioned between the outer peripheral face of accommodation section 11 and housing 14, one opening is located on the inwall of accommodation section 11 simultaneously, another opening is located on the outer peripheral face of housing 14, so just can be communicated with accommodation section 11 and LED shot-light 10 space outerpaces, make a part of hot-air in accommodation section 11 can flow to space outerpace, this first heat dissipation channel 12 is located at the top of LED shot-light 10 conventionally.The second heat radiation conduit 15 is arranged on the wall body of accommodation section 11, be used for being communicated with accommodation section 11 and heat dissipation channel 13, portion of air in heat dissipation channel 13 just can enter into accommodation section 11 by this second heat radiation conduit 15 like this, and then outwards flows out by the first heat radiation conduit 12.Heat dissipation channel 13, the second heat radiation conduit 15, accommodation section 11 and the first heat radiation conduit 12 have formed a ventilating path (as shown in Figure 2), this ventilating path can effectively be accelerated the radiating rate of accommodation section 11, its groundwork principle is: the luminous generation heat of the interior LED light source in accommodation section 11, whole accommodation section 11 temperature are raise, a heat part for accommodation section 11 is on its wall body, therefore air in heat dissipation channel 13 absorbs the heat on wall body and raises, another part is present in the air in accommodation section 11, air in accommodation section 11 goes out to outside spatial flow from the first heat radiation conduit 12 after being heated, now the air pressure in accommodation section 11 diminishes, because the air themperature in heat dissipation channel 13 must lower than the air themperature in accommodation section 11, (temperature of accommodation section 11 be through repeatedly passing to heat dissipation channel 13 after conduction again, temperature will inevitably decrease to some degree), make air pressure in heat dissipation channel 13 lower than the air pressure in accommodation section 11, therefore can flow in accommodation section 11 by the second heat radiation conduit 15, and simultaneously the air pressure in heat dissipation channel 13 also diminishes with respect to space outerpace, the cold air of space outerpace just can enter heat dissipation channel 13 like this, whereby by heat dissipation channel 13, the second heat radiation conduit 15, accommodation section 11 and the first ventilating path of forming of heat radiation conduit 12 continual with extraneous air 20 convection current, its heat continues to flow out from the first heat radiation conduit 12, realize the object of heat radiation, as shown in Figure 2.
Preferably, the second heat radiation conduit 15 is located on accommodation section 11, make accommodation section 11 can be fully and heat dissipation channel 13 realize cross-ventilation, conventionally shot-light is all cylindrical structural, therefore accommodation section 11 is also generally cylindrical structural, and (other shapes are also feasible certainly, as rectangle, rectangle etc.), the second heat radiation conduit 15 be located on the air that can fully make on accommodation section 11 to enter accommodation section 11 by the second heat radiation conduit 15 effectively with accommodation section 11 in LED light source heat-shift.Preferably, the second heat radiation conduit 15 is palisade, can increase like this convection current between the second heat radiation conduit 15 and heat dissipation channel 13.Certainly, also the second heat radiation conduit 15 can be set to poroidly, but compared to palisade, the area that can offer is larger, and grating structure can make the air velocity that moment is passed through the second heat radiation conduit 15 become large simultaneously, has accelerated the cross-ventilation between accommodation section 11 and heat dissipation channel 13.
In the application's a preferred embodiment, heat dissipation channel 13 has the first opening 131 and the second opening 132, the first opening 131 and the second opening 132 have difference in height on horizontal level, adopt such structure, be in order to make heat dissipation channel 13 can form a stack effect, make to be dispersed into housing 14 space outerpaces via a part of heat absorbing on 11 wall bodies of accommodation section by heat dissipation channel 13 stack effects own.Preferred the first opening 131 is located at the top of LED shot-light 10, and the second opening 132 is located at the bottom of LED shot-light 10, and two openings of heat dissipation channel 13 adopt such design, is mainly to consider to utilize most effectively stack effect.Because on the one hand than sidewall, top end opening can be conducive to hot-air and flow out fast, and being also conducive to cold air, bottom end opening enters LED shot-light 10, between the export and import of air, there is on the other hand maximum difference in height, difference between its air pressure of living in is also maximum whereby, can effectively help air to enter LED shot-light 10.
Preferably, the sectional area of at least one heat dissipation channel 13 diminishes gradually along the axial direction of LED shot-light 10, adopts such structure, makes whole heat dissipation channel 13 low wide and up narrow, the air pressure of passing through bottom to a certain degree makes hot-air flow to top, strengthens the effect of stack effect.
Preferably, heat dissipation channel 13 also has the 3rd opening 133, as shown in Figure 3, it is located on the housing 14 of LED shot-light 10, for strengthening the air mass flow of heat dissipation channel 13, the 3rd opening 133 can increase the amount of the air that enters heat dissipation channel 13 effectively, further plays the effect of strengthening its inner air circulation, improves whereby the radiating effect of LED shot-light 10.
Should be noted that, embodiment of the present utility model has preferably implementation, and not the utility model is done to any type of restriction, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement to change or be modified to the effective embodiment being equal to, in every case do not depart from the content of technical solutions of the utility model, any amendment or equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
