本創作係關於一種光源模組及應用此光源模組的發光組件，特別是關於一種利用氣液相變散熱循環進行冷卻的光源模組及應用此光源模組的發光組件。The present invention relates to a light source module and a light-emitting component using the light source module, and more particularly to a light source module using a gas-liquid phase heat-dissipating cycle for cooling and a light-emitting component using the light source module.
發光二極體(Light-Emitting Diode，LED)光源作為一種新興之發光件，雖然現在還不能大規模取代傳統之白熾燈，但其具有工作壽命長、節能、環保等優點，因而普遍被市場所看好。此外，目前由多個發光二極體組成之模組能產生大功率、高亮度之光源，完全可以取代現有白熾燈實現室內外照明，也預期將廣泛且革命性地取代傳統之白熾燈等現有之光源，進而成為符合節能環保主題的主要發光件。Light-Emitting Diode (LED) light source is an emerging light-emitting element. Although it can not replace traditional incandescent lamps on a large scale, it has the advantages of long working life, energy saving and environmental protection. I am optimistic. In addition, the module consisting of multiple light-emitting diodes can produce high-power, high-brightness light sources, which can completely replace the existing incandescent lamps for indoor and outdoor lighting. It is also expected to replace the existing incandescent lamps widely and revolutionarily. The light source has become the main light-emitting part that meets the theme of energy conservation and environmental protection.
然而，目前發光二極體的散熱方式，大多是利用熱傳導進行散熱，其效果不甚理想，且散熱鰭片需鄰近發光二極體，進而造成了電子裝置之空間設計上的困難。因此，如何設計出一種發光二極體的散熱系統，能夠有效的冷卻發光二極體，還能具有良好的空間設計彈性，實為業界相關研發人員極需解決的重要問題。However, at present, most of the heat dissipation methods of the light-emitting diodes use heat conduction for heat dissipation, and the effect thereof is not satisfactory, and the heat dissipation fins need to be adjacent to the light-emitting diodes, thereby causing difficulty in space design of the electronic device. Therefore, how to design a heat dissipation system for a light-emitting diode can effectively cool the light-emitting diode, and also has good space design flexibility, which is an important problem that the relevant research and development personnel in the industry need to solve.
鑒於以上的問題，本創作是關於一種光源模組及應用此光源模組的發光組件，藉以改善目前發光二極體之散熱效果不佳的問題。In view of the above problems, the present invention relates to a light source module and a light-emitting component using the same, thereby improving the problem of poor heat dissipation of the current light-emitting diode.

One side of the heat sink is in thermal contact with the light emitting member. The heat sink has a first chamber, a second chamber, and a second flow path connected between the first chamber and the second chamber. The distance from the second chamber to the illuminating member is greater than the distance from the first chamber to the illuminating member, and the first chamber is filled with a working fluid. When the working fluid absorbs the heat generated by the illuminating member, the working fluid is vaporized into a gas type by the liquid type, and flows into the second chamber by one of the two flow paths for heat dissipation. After the working fluid in the second chamber is condensed into a liquid form by the gas type, it is returned to the first chamber by the other of the second flow paths.
此外，本創作還提供了一種發光組件，包含一罩蓋以及複數個光源模組。複數個光源模組設置於罩蓋之一側。複數個光源模組個別包含一發光件以及一散熱件。散熱件之一側熱接觸於發光件。散熱件具有一第一腔室、一第二腔室以及連接於第一腔室及第二腔室之間的二流道。第二腔室至發光件的距離大於第一腔室至發光件的距離，且第一腔室內填充有一工作液。當工作液吸收發光件產生之熱時，工作液由液體型態汽化成氣體型態，並由二流道之一流入第二腔室以進行散熱。而位於第二腔室之工作液由氣體型態凝結成液體型態後，係由二流道之另一回流至第一腔室。In addition, the creation also provides a lighting assembly comprising a cover and a plurality of light source modules. A plurality of light source modules are disposed on one side of the cover. The plurality of light source modules individually include a light emitting member and a heat sink. One side of the heat sink is in thermal contact with the light emitting member. The heat sink has a first chamber, a second chamber, and a second flow path connected between the first chamber and the second chamber. The distance from the second chamber to the illuminating member is greater than the distance from the first chamber to the illuminating member, and the first chamber is filled with a working fluid. When the working fluid absorbs the heat generated by the illuminating member, the working fluid is vaporized into a gas type by the liquid type, and flows into the second chamber by one of the two flow paths for heat dissipation. After the working fluid in the second chamber is condensed into a liquid form by the gas type, it is returned to the first chamber by the other of the second flow paths.

本創作第一實施例之光源模組10包含一發光件 12及一散熱件14。本創作之發光件12為固態發光元件，而在本實施例中，發光件12以一發光二極體(Light-Emitting Diode，LED)為例，但並不以此為限。散熱件14具有一第一本體141、一第二本體142、一第一腔室145、一第二腔室146、二流道148、一散熱鰭片組149及一工作液19。The light source module 10 of the first embodiment of the present invention includes a light emitting part 12 and a heat sink 14. The light-emitting component 12 of the present invention is a solid-state light-emitting component. In the present embodiment, the light-emitting component 12 is exemplified by a light-emitting diode (LED), but is not limited thereto. The heat sink 14 has a first body 141, a second body 142, a first chamber 145, a second chamber 146, a second flow path 148, a heat sink fin set 149, and a working fluid 19.
第一本體141之一側熱接觸發光件12。第一腔室145位於第一本體141內部。第二腔室146位於第二本體142內部。散熱鰭片組149設置於第二本體142上。二流道148位於第一腔室145及第二腔室146之間且連通第一腔室145及第二腔室146。需注意的是，在本實施例中，流道148的數量為二，但並不以此為限。在其他實施例中，流道148的數量可以視實際情況做調整。第二腔室146至發光件12的距離大於第一腔室145至發光件12的距離。第一腔室145內填充有一工作液19。在本實施例中，工作液19為水，但並不以此為限。在其他實施例中，工作液19也可以是冷煤、甲醇、乙醇、乙醚或為其他可輔助熱傳導之液態物質。此外，在本實施例中，流道148的橫截面積A1遠小於第二腔室146的橫截面積A2。One side of the first body 141 is in thermal contact with the illuminating member 12. The first chamber 145 is located inside the first body 141. The second chamber 146 is located inside the second body 142. The heat dissipation fin group 149 is disposed on the second body 142. The second flow path 148 is located between the first chamber 145 and the second chamber 146 and communicates with the first chamber 145 and the second chamber 146. It should be noted that, in this embodiment, the number of the flow channels 148 is two, but is not limited thereto. In other embodiments, the number of runners 148 can be adjusted as appropriate. The distance from the second chamber 146 to the illuminating member 12 is greater than the distance from the first chamber 145 to the illuminating member 12. The first chamber 145 is filled with a working fluid 19. In the present embodiment, the working fluid 19 is water, but is not limited thereto. In other embodiments, the working fluid 19 can also be cold coal, methanol, ethanol, diethyl ether or other liquid materials that can assist in heat transfer. Further, in the present embodiment, the cross-sectional area A1 of the flow path 148 is much smaller than the cross-sectional area A2 of the second chamber 146.
接下來將針對散熱件14將發光件12產生之熱散出的過程進行說明。Next, the process of dissipating heat generated by the light-emitting member 12 for the heat sink 14 will be described.
當發光件12產生熱時，熱能係傳導至第一本體141內之第一腔室145，而第一腔室145內的工作液19吸收發 光件12產生之熱後，係由液體型態汽化成氣體型態的工作液19’。氣體型態的工作液19’會上升並從二流道148之一沿著一第一方向D1流至第二本體142內部的第二腔室146(如第二圖所示)。在本實施例中，由於散熱鰭片組149設置於第二本體142上，氣體型態工作液19’的熱能可藉由散熱鰭片組149散出至外部環境，但並不以此為限。在其他實施例中，氣體型態工作液19’的熱能也可以直接藉由第二本體142散出至外部環境。由於氣體型態工作液19’在流入第二腔室146後散出其本身的熱能，故氣體型態工作液19’會逐漸凝結成為原本液體型態的工作液19。此時，液體型態的工作液19會流入二流道148之另一並沿著一第二方向D2回流至第一腔室145。此外，在本實施例中，由於流道148的橫截面積A1遠小於第二腔室146的橫截面積A2，使流道148與第二腔室146之間具有壓力差。如此一來，氣體型態的工作液19’係沿著第一方向D1以一噴射氣流R1的型態噴流至第二腔室146，藉此加速導熱及對流。When the illuminating member 12 generates heat, the thermal energy is transmitted to the first chamber 145 in the first body 141, and the working fluid 19 in the first chamber 145 absorbs the hair. After the heat generated by the optical member 12 is vaporized into a gas-type working fluid 19' by a liquid type. The gaseous working fluid 19' will rise and flow from one of the second flow passages 148 along a first direction D1 to a second chamber 146 (as shown in the second figure) inside the second body 142. In this embodiment, since the heat dissipation fin group 149 is disposed on the second body 142, the heat energy of the gas type working fluid 19' can be dissipated to the external environment by the heat dissipation fin group 149, but is not limited thereto. . In other embodiments, the thermal energy of the gaseous working fluid 19' may also be dissipated directly to the external environment by the second body 142. Since the gaseous type working fluid 19' dissipates its own thermal energy after flowing into the second chamber 146, the gaseous type working fluid 19' gradually condenses into the working liquid 19 of the original liquid type. At this time, the liquid type working fluid 19 flows into the other of the second flow paths 148 and flows back to the first chamber 145 along a second direction D2. Further, in the present embodiment, since the cross-sectional area A1 of the flow path 148 is much smaller than the cross-sectional area A2 of the second chamber 146, there is a pressure difference between the flow path 148 and the second chamber 146. In this manner, the gaseous working fluid 19' is jetted to the second chamber 146 in a pattern of the jet stream R1 along the first direction D1, thereby accelerating heat conduction and convection.
上述本創作第一實施例之光源模組10中，工作液19會汽化成為氣體型態工作液19’以加速導熱，且氣體型態工作液19’會從二流道148之一流至第二腔室146進行散熱。而氣體型態工作液19’凝結成為原本液體型態的工作液19後，會經由二流道148之另一回流至第一腔室145，藉此形成一循環閉迴路，再進而利用此循環閉迴路自然對流的方式 達成更佳的散熱效果，還可省去主動元件的設置。此外，由於二流道148的設置，本實施例之光源模組10可以遠端散熱，亦即導熱部分的結構與散熱部分的結構可以分離，令整體結構上的空間設計更為方便。在本實施例中，氣體型態的工作液19’係沿著第一方向D1以噴射氣流R1的型態噴流至第二腔室146，藉此加速導熱及對流以增進導熱效率。In the light source module 10 of the first embodiment of the present invention, the working fluid 19 is vaporized into a gas-type working fluid 19' to accelerate heat conduction, and the gas-type working fluid 19' flows from one of the second flow passages 148 to the second chamber. The chamber 146 performs heat dissipation. After the gas type working fluid 19' is condensed into the original liquid type working fluid 19, it is returned to the first chamber 145 via the other of the second flow passages 148, thereby forming a circulation closed loop, and then using the circulation closed The way the loop naturally convection Achieve better heat dissipation and eliminate the need for active components. In addition, due to the arrangement of the second flow path 148, the light source module 10 of the present embodiment can dissipate heat at a distal end, that is, the structure of the heat conducting portion and the structure of the heat dissipating portion can be separated, which makes the space design on the overall structure more convenient. In the present embodiment, the gaseous working fluid 19' is sprayed in the first direction D1 in the form of the jet stream R1 to the second chamber 146, thereby accelerating heat conduction and convection to improve heat transfer efficiency.

The first chamber 245, the second chamber 246, and the second flow passage 248 are located inside the body 241. The heat dissipation fin group 249 is disposed on a side of the body 242 away from the light emitting member 22 .

此外，由於流道的橫截面積遠小於第二腔室的橫 截面積，使流道與第二腔室之間具有壓力差。藉此，氣體型態的工作液以噴射氣流的型態噴流至第二腔室，藉此加速導熱及對流，以達到增進導熱效率的效果。In addition, since the cross-sectional area of the flow channel is much smaller than the cross-section of the second chamber The cross-sectional area has a pressure difference between the flow path and the second chamber. Thereby, the gaseous working fluid is sprayed into the second chamber in the form of the jet stream, thereby accelerating the heat conduction and the convection to achieve the effect of improving the heat conduction efficiency.
