For above and other objects of the present invention, feature and advantage can be become apparent, an embodiment cited below particularly, and cooperate appended diagram, be described in detail below.
Description of drawings
Fig. 1 is the schematic top plan view of the light emitting diode radiating module of one embodiment of the invention.
Fig. 2 is the schematic side view of Fig. 1.
Embodiment
Inveteracy for a long time technology prejudice thinks that the power consumption of light-emitting diode is low, does not therefore need additionally to use radiator to come the auxiliary light emission diode radiating.But light-emitting diode still can produce heat when converting electrical energy into luminous energy, therefore causes the temperature of light-emitting diode surrounding environment also and then to raise.If the temperature continuous high temperature of light-emitting diode surrounding environment will make the speed of light-emitting diode decline accelerate, therefore can have influence on the useful life of light-emitting diode.In addition, the temperature continuous high temperature of light-emitting diode surrounding environment also can make the optical wavelength skew of light-emitting diode easily, and then influences the optical effect of light-emitting diode.
In addition because the shape of heat pipe, in the time of therefore on considering light-emitting diode is configured in the heat pipe of tubular, how can because this inveteracy technology prejudice think light-emitting diode is configured on the heat pipe of tubular type, have the degree of difficulty of enforcement.
Fig. 1 is the schematic top plan view of the light emitting diode radiating module of one embodiment of the invention, and Fig. 2 is the schematic side view of Fig. 1.Please also refer to Fig. 1 and Fig. 2, light emitting diode radiating module 100 comprises heat pipe 110, light-emitting diode 120 and radiator 130.
Hold above-mentioned, for allow light-emitting diode 120 and radiator 130 both one of them can firmly be configured on the heat pipe 110 at least, light emitting diode radiating module 100 also comprises a fastener (figure do not show), and light-emitting diode 120 and radiator 130 both one of them is to be fixed on the heat pipe 110 by fastener at least.In addition, light-emitting diode 120 and radiator 130 both one of them also can be to utilize modes such as adhesion layer bonding, locking part locking to be fixed on the heat pipe 110 at least, wherein adhesion layer comprises hot-setting adhesive or tin cream, and locking part can be screw.Those skilled in the art can be by this specification or other disclosed file, knows easily and association is disposed at the method at the two ends of heat pipe 110, just no longer explanation herein with light-emitting diode 120, radiator 130.
When applying electric current in light-emitting diode 120, the electronics of light-emitting diode 120 inside can combine with the hole, and the energy of surplus is disengaged with the form of light, heat release simultaneously.At this moment, the heat of light-emitting diode 120 can conduct to heat pipe 110 apace through substrate 122, is gas and be positioned in the heat pipe 110 can gasify behind the heated liquid in hot junction.The weight of gas is light and rise, and the change of pressure space that the liquid flow that is positioned at cold junction is stayed with the gas of filling up rising.The gas and the liquid that flow are convenient to form in the heat pipe 110 a pair of flow phenomenon.
Specifically, the cold junction equipped with radiator 130 of heat pipe 110, therefore when hot-air convection during to the cold junction of heat pipe 110, heat can be passed to radiator 130 apace, and is emitted in the cold air on every side by radiator 130.At this moment, the gas that heat is pulled away can condensation form liquid, and flows to the hot junction of heat pipe 110 once more.Light emitting diode radiating module 100 is by these heat radiation steps that circulate, and heat energy is dissipated in the colder on every side environment enough apace.
Those skilled in the art can know the internal work principle of heat pipe 110 via disclosed file, thus in this specification only with character narrate, just cooperate explanation with diagram no longer in addition.
From the above, light emitting diode radiating module 100 is by substrate 122 heat of light-emitting diode 120 to be conducted to heat pipe 110 apace, mode by thermal convection then, heat is passed to cold junction by the hot junction of heat pipe 110 apace, utilizes radiator 130 at last again with in the environment colder around the heat dissipation extremely that will be passed to cold junction.Compared to known, light emitting diode radiating module 100 is to utilize heat pipe 110 and the assisting of radiator 130 of arranging in pairs or groups dispelled the heat, and therefore can effectively promote the radiating effect of light emitting diode radiating module 100.
When light emitting diode radiating module 100 can dispel the heat effectively, light-emitting diode 120 just can be possessed its good optical effect, also can prolong its useful life simultaneously.
Specifically, because the shape of heat pipe 110 makes things convenient for the designer to design according to the user demand of reality, for example be strip, horse-hof shape or other shape, also can also elongate or shorten simultaneously the length of heat pipe 110 according to user demand.Thus, the position that the designer can first fixed heat sink 130 is selected the shape and the length of heat pipe 110 then according to user demand, and light emitting diode radiating module 100 just has locational configuration elasticity, and assembling space simultaneously also can avoid waste.
In sum, light emitting diode radiating module of the present invention has following advantage at least:
One, at least one end improvement with heat pipe is flat, makes the light-emitting diode can be directly and entirely be attached on the heat pipe, has overcome known inveteracy technology prejudice.
Two, utilize heat pipe and radiator, light emitting diode radiating module can efficiently radiates heat, so light-emitting diode can have the good optical effect, prolongs its useful life simultaneously.
Three, the user can design the shape and the length of heat pipe according to demand, so light emitting diode radiating module has locational configuration elasticity, and assembling space simultaneously also can avoid waste.
Though the present invention discloses as above with an embodiment; right its is not in order to limit the present invention; any the technical staff in the technical field; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
