Phase changeable light source module with variable angle

The present invention relates to a phase change light source module, and more particularly to a phase change heat dissipation light source module with variable angle.

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.

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. In addition, the illumination range of a general light-emitting diode lamp is fixed, and the user cannot adjust the illumination angle and its range. When the user needs to illuminate the luminaire to other areas, additional luminaires may need to be added, which will greatly increase the cost. Therefore, how to design a heat dissipation system for a light-emitting diode can effectively cool the light-emitting diode and increase the illumination range, which is an important problem that the relevant R&D personnel in the industry need to solve.

In view of the above problems, the present invention relates to a phase change heat-dissipating light source module capable of changing angles, thereby improving the current heat-dissipating effect of the light-emitting diode and the inability to adjust the illumination range.

The variable angle phase change heat dissipation light source module of an embodiment of the present invention comprises a light emitting component 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 two flexible flow tubes. The flexible flow tube is respectively connected between the first chamber and the second chamber in a flexible manner, 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 flexible flow tubes to dissipate heat, and the working fluid located in the second chamber is After the gas type is condensed into a liquid form, it is returned to the first chamber by the other of the two flexible flow tubes.

The changeable angle phase change heat dissipating light source module of the present invention forms a closed loop by the arrangement of the two flexible flow tubes, and conducts heat conduction by using the gas-liquid change of the working fluid to convect in the closed loop, and the structural design does not need The active components are driven and can achieve a significant increase in heat dissipation efficiency. Furthermore, the first chamber connecting the illuminating members can change the relative position of the illuminating member and the second chamber by bending the flexible flow tube, thereby changing the irradiation angle of the illuminating member. In this way, the user can manually change the range of illumination of the illuminating device according to the demand at the time, so as to enhance the function of the phase change light source module.

In this embodiment and some other embodiments, the illuminating member 12 is a solid-state illuminating element. In the embodiment, the illuminating member 12 is exemplified by a Light-Emitting Diode (LED), but This is limited to this.

The detailed structure of the heat sink 14 will be described below. Please refer to FIG. 2, which is a cross-sectional view of the phase change light source module of the variable angle of FIG. 1 at the first position.

The heat sink 14 has a first body 141, a second body 142, a first chamber 145, a second chamber 146, two flexible flow tubes 148, a heat sink fin set 149, and a working fluid 19.

Furthermore, 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 two flexible flow tubes 148 are respectively flexibly coupled between the first chamber 145 in the first body 141 and the second chamber 146 in the second body 142. The heat dissipation fin group 149 is disposed on the second body 142. The second body 142 has a bottom surface 1425. The bottom surface 1425 is located between the second chamber 146 and the first body 141 and faces the first body 141. It should be noted that the first chamber 145 can be changed in its relative position to the second chamber 146 by bending of the flexible flow tube 148. Moreover, in the present embodiment, the number of flexible flow tubes 148 is two, but is not limited thereto. In other embodiments, the number of flexible flow tubes 148 can be adjusted as appropriate. The distance from the second chamber 146 to the illuminating member 12 is greater than that of the first chamber 145 to the illuminating member 12 distance. 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 flexible flow tube 148 is much smaller than the cross-sectional area A of the second chamber 146. In the present embodiment, the two flexible flow tubes 148 respectively include a plurality of rings 1481 that are connected in series to each other. With such a configuration, the flexible flow tube 148 is bent and the working fluid 19 is prevented from flowing out of the ring body 1481. In other words, the second flexible flow tube 148 is a bellows tube or a metal tube that is flexed in a machined manner.

The detailed structure and arrangement position of the light-emitting member 12 will be described below. Please continue to refer to "Fig. 2". In this embodiment and some other embodiments, the illuminating member 12 has a light emitting surface 125. Taking "Fig. 2" as an example, in the normal state, the normal vector N1 of the light-emitting surface 125 is at an angle θ1 with an absolute vertical direction V, and the angle θ1 is about 45 degrees, but not limited thereto. A user can move the first body 141 in a hand-held manner, and the flexible flow tube 148 is bent to change the relative position of the first chamber 145 and the second chamber 146, thereby adjusting the corresponding position of the light surface 125. Thus, taking "Fig. 1" and "Fig. 3" as an example, it is a sectional view of the phase change light source module of the variable angle of "Fig. 1" at the second position, and the normal vector N2 of the light exiting surface 125. Parallel to an absolute vertical direction V, but not limited to this. In other embodiments, the "figure 4" is taken as an example, which is a cross-sectional view of the phase change light source module of the variable angle of "Fig. 1" at the third position. The normal vector N2 of the light-emitting surface 125 is at an angle θ2 with an absolute vertical direction V, and the angle θ2 is about 90 degrees. In this way, the phase change light source module 10 can be directly directed downward without affecting heat dissipation efficiency.

The absolute vertical direction V system described herein is the same as the direction of gravity.

Next, the process of dissipating heat generated by the light-emitting member 12 for the heat sink 14 will be described. Referring to FIG. 2, 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 heat generated by the illuminating member 12. Thereafter, it is vaporized into a gaseous form of working fluid 19' from a liquid form. The gaseous working fluid 19' will rise and flow from one of the two flexible flow tubes 148 along a first direction D1 to a second chamber 146 inside the second body 142 (as shown in Figure 2). . 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 two flexible flow tubes 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 flexible flow tube 148 is much smaller than the cross-sectional area A of the second chamber 146, there is a pressure difference between the flexible flow tube 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.

In the phase change 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 is The working fluid 19' will flow from one of the two flexible flow tubes 148 to the second chamber 146 for 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 two flexible flow tubes 148, thereby forming a circulation closed loop, and then utilizing This closed-loop natural convection approach achieves better heat dissipation and eliminates the need for active components. In addition, due to the arrangement of the two flexible flow tubes 148, the phase change light source module 10 of the present embodiment can dissipate heat at a remote end, that is, the structure of the heat conducting portion and the structure of the heat radiating portion can be separated, so that the space design of the overall structure is more Convenience. 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.

In addition, the phase change lamp module of the variable angle of the present invention can also be used as a projection lamp of different angles if a high-power light-emitting component is selected.

According to the phase change light source module of the variable angle according to the above embodiment, a loop closed loop is formed by the arrangement of the two flexible flow tubes, and heat is transferred by convection in the circulating closed loop by the gas-liquid change of the working fluid. The design does not require active components for driving, and can achieve a significant increase in heat dissipation efficiency. Moreover, the first chamber connecting the illuminating members changes the relative position of the illuminating member and the second chamber by bending the flexible flow tube, thereby changing the irradiation angle of the illuminating member and the range thereof. In this way, the user manually changes the illumination angle of the illuminating device according to the demand at that time to illuminate to different regions. Thereby, the use function of the phase change light source module with variable angle is improved.
