Lighting device

The present invention relates to a lighting device, and more particularly to a lighting device having high performance.

Generally, traditional fish collection lamps use tungsten wire, double metal bulbs or high intensity gas discharge lamps (HID). These fishlights of radial light sources, only 20% of the light is shining on the sea, and at least 80% of the other light is dissipated in the air, thus resulting in low efficiency and high energy consumption.

In order to improve the traditional fishing light source of a conventional light source, a conventional light source is replaced by a light emitting diode (LED) having high directivity. However, the light-emitting diode is disposed on the aluminum substrate, and the light-emitting diode is guided to the heat-dissipating fin by the heat-radiating paste contacting the heat pipe. It can be seen that there is a high thermal resistance in this heat dissipation path. Furthermore, since the fish-collecting lamp using the light-emitting diode as a light source does not have the function of self-generation, it is necessary to additionally add a generator or install a battery, so that the volume cannot be miniaturized and the weight cannot be effectively reduced.

The invention provides a lighting device which has the advantages of low thermal resistance, small volume, high efficiency and self-generation.

The lighting device of the present invention comprises a tube body, a light emitting diode unit and a heat dissipating fin set. The tube body includes a light transmitting portion and a heat conducting portion connected to the light transmitting portion, wherein a fluid is disposed in the tube body. The light emitting diode unit is disposed in the light transmitting portion of the pipe body and is located in the fluid. The heat dissipation fin set is fixed to a peripheral surface of the heat transfer portion of the pipe body.

Based on the above, in the design of the illumination device of the present invention, the light-emitting diode unit is disposed in the light-transmitting portion of the tube body, and the fluid is disposed in the tube body, and the heat-dissipating fin group is fixed on the peripheral surface of the heat-conducting portion. Therefore, the heat generated by the LED unit can directly dissipate heat through the heat exchange of the fluid in the tube body and the heat dissipation fin group, thereby effectively reducing the thermal resistance and having a better heat dissipation effect. Further, since the illumination device of the present invention uses the light-emitting diode unit as a light source, it has directivity and can reduce power consumption, and can have an advantage of high performance.

The above described features and advantages of the invention will be apparent from the following description.

FIG. 1 is a perspective view of a lighting device according to an embodiment of the invention. 2 is a perspective exploded view of the lighting device of FIG. 1. 3 is a cross-sectional view of the lighting device of FIG. 1. 4 is a partial cross-sectional view of the illumination device of FIG. 1 from another perspective. Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the illumination device 100 of the present embodiment includes a tube body 110 , a light emitting diode unit 120 , a generator 130 , and a heat dissipation fin set 140 . The tube body 110 includes a light transmitting portion 112 and a heat conducting and heat conducting portion 114 connected to the light transmitting portion 112. A fluid F is disposed inside the tubular body 110 for heat dissipation. The light emitting diode unit 120 is disposed in the light transmitting portion 112 of the tube body 110 and is located in the fluid F. The heat transfer portion 114 of the generator 130 connecting the pipe body 110 is relatively far from the one end 114a of the light transmitting portion 112, wherein the generator 130 is, for example, a wind power generator. The heat dissipation fin set 140 is fixed to a peripheral surface 114b of the heat transfer portion 114 of the pipe body 110. When the heat sink fin set 140 is subjected to an external force (for example, wind) to rotate the pipe body 110, the pipe body 110 drives the generator 130 to rotate synchronously, so that the generator 130 converts a kinetic energy into an electric energy.

In detail, the tube body 110 of the embodiment is configured by the heat conducting portion 114 connected to the light transmitting portion 112, wherein the light transmitting portion 112 of the tube body 110 is a light transmissive material, such as glass or plastic, to allow the light emitting unit The light emitted by the polar body unit 120 can be permeable; and the heat conducting portion 114 is a material having a heat conducting effect, such as a metal material, preferably copper, which can quickly transfer thermal energy in the tube body 110 to the outside. The fluid F is, for example, a non-conductor, such as a pure water, which is disposed inside the tubular body 110, wherein the total amount of the fluid F can be increased or decreased according to requirements, and is not limited thereto.

The LED unit 120 is composed of a substrate (not shown) and a plurality of LEDs (not shown) disposed on the substrate, wherein the LEDs are arranged in an array on the substrate and adapted A light (not shown) is emitted, and the light can pass through the light transmitting portion 112 to emit light. The light emitting diode unit 120 is disposed in the fluid F (such as a non-conductor). Since the ion concentration in the fluid F is very low, the electrical properties of the light emitting diode unit 120 are less affected by the fluid F. The heat generated by the LED unit 120 heats the fluid F in the light transmitting portion 112 to change the fluid F from a liquid state to a gaseous state, and the gaseous fluid F is pushed by the vapor pressure to flow into the heat conducting portion 114 for heat exchange. Direction L1 in 4. The heat conducting portion 114 of the tube body 110 can be affected by the external environment to cool the gaseous fluid F in the heat conducting portion 114 to be converted into a liquid state, and return to the light transmitting portion 112 again, that is, the direction L2 in FIG. That is to say, the fluid F of the present embodiment can circulate between the light transmitting portion 112 and the heat conducting portion 114 to transmit a cyclic phase change (ie, a liquid state to a gaseous state, and then a gaseous state to a liquid state) to the light emitting diode. The body unit 120 performs heat dissipation.

As shown in FIG. 3, one end 114a of the heat conducting portion 114 directly contacts the rotating shaft 132 of the generator 130, and the coupling 150 covers one end 114a of the heat conducting portion 114 and the rotating shaft 132 of the generator 130 to fix the two together. That is, when the tubular body 110 is rotated, the generator 130 can rotate synchronously with the tubular body 110.

The heat dissipating fin set 140 is fixed on the peripheral surface 114b of the heat conducting portion 114. When the heat dissipating fin set 140 is subjected to an external force (for example, a wind force) to rotate the tubular body 110, the heat transmitting fin set 140 can be simultaneously driven through the coupling 150 to be fixed. Together with the rotating shaft 132 of the generator 130, the generator 130 is also synchronized with the rotation of the tubular body 110. In this way, the generator 130 can convert kinetic energy into electrical energy for use by the light emitting diode unit 120, so that the lighting device 100 has the advantage of self-power generation. Here, the heat dissipation fin set 140 can effectively increase the heat dissipation area of the illumination device 100, so that the illumination device 100 can have a better heat dissipation effect.
