New description: [New technical field] This creation is about a lighting device, especially a lighting device that improves the heat dissipation effect. [Prior Art] Currently, electric lamps on the market usually use fluorescent tubes. However, in order to meet environmental protection requirements, the illumination source using the LED is significantly better than the fluorescent tube. In order to increase the application of the light-emitting diode in the lighting fixture, how to dissipate heat to avoid burning of the LED during the lighting process has always been one of the development priorities of the LED lighting fixture. The heat dissipation method of the conventional light-emitting diode lighting device is to conduct the heat energy generated by the light-emitting diode during the light-emitting process to the heat-dissipating component, and then conduct or radiate the heat energy to the surrounding air through a relatively large-area heat-dissipating component. .

In order to increase the light-emitting brightness of the illumination device, a high-wattage light-emitting diode is usually used, for example, a three-light-emitting diode of 3 watts or more is used. The outer casing module 130 includes a connecting base 131, a base 132 and a plurality of II pieces 133. The plurality of tabs 133 form a heat dissipating member and are disposed at one end of the base 132, and the connecting seat 131 is disposed at the other end of the base 132.

The plurality of light-emitting diodes 121 are thermally coupled to a plurality of Korean sheets 133 for conducting heat generated by the light-emitting diodes mi. Since the heat dissipating member formed by the plurality of fins 133 is provided, the heat dissipating area can be increased so that thermal energy is conducted or rotated from a large area to the surrounding air, thereby lowering the temperature of the light emitting diode 121. However, if the air in the space defined by the plurality of fins 133 lacks fluidity, the heat dissipation effect of the light-emitting diode 121 and the illumination device 1〇〇 will be affected. Therefore, the conventional illumination device 1 is still improved. Space.

After being conducted to the outer casing module 230 through the first liquid, it is conducted to the external environment. The substrate 222 can be a printed circuit board having a circuit coupled to an external power source and electrically connecting the light emitting diodes 221, so that an external power source can supply current to the light emitting diodes 221 through the foregoing circuits. The outer casing module 230 includes a base 23 and a base 233. The portion of the connector 231 for connecting an external power source is a screw connector. The outer casing 233 7 M406685 is disposed at one end of the base 232, and the connecting base 231 is disposed at the other end of the base 232. The first enclosed space 251 is located within the outer casing 233. The first liquid is thermally conductively contacted to the back surface of the substrate 222, whereby heat generated by the light-emitting diode 221 is conducted to the first liquid through the substrate 222. In the present embodiment, the first liquid directly contacts the back surface of the substrate 222. In one embodiment, the first liquid may also be in thermal conductive contact with the back surface of the substrate 222 (to be described later) via a heat sink. The first liquid convects due to the temperature difference in the first closed space 251, and the heat dissipation effect on the light source module 220 is increased. In particular, in the case where the light-emitting diode 221 emits light downward, in this embodiment, the portion of the first liquid that is heated is below, and the first liquid that is under the heat becomes smaller after being heated and flows upward, and the first liquid above A lower temperature density will flow down, thus creating a convection caused by both gravity and temperature differences. The convection effect of the convection generated by the two factors of gravity and temperature difference is greater than the heat transfer effect of the convection formed by the temperature difference. Further, since the specific heat of the first liquid is higher than that of the air, it is possible to absorb more heat and generate heat convection, and thus has a better heat transfer effect, so that the outer casing 233 may not contain a Korean sheet useful for increasing the heat conduction area. The outer casing 233 is made of a - die scale. It can also be formed by stamping. In the present embodiment, the outer surface of the outer casing 233 is a round fox surface. Therefore, the shape of the substrate 222 of the light source module 22 is - circular. And the outer casing 233 may be a thin metal plate for conducting heat generated by the light-emitting diodes 22! to the external environment. Connected to the external power supply (not shown), the external power supply provides an AC 8 pi406685 to the LED driver circuit 210 (described later). Further, it should be understood that the present creation is not limited to the above embodiment, and in order to increase the heat dissipation effect, the outer casing 233 may be provided with fins having an increased heat conduction area as in the prior art. In an embodiment t, when the light source module 220 is disposed in the space, the space is formed with a second enclosed space 252 between the light source module 22 and the light-transmitting cover 240, and is disposed in the second enclosed space 252. The second liquid is injected to conduct heat generated by the light source module 220 to the light-transmissive cover 240, and then transmitted to the external environment. For the second liquid, when the light-emitting diode 221 emits light upward, a better convection is formed. Further, the first liquid may be water; or the Silicone Oil is also called dimethyl. Polydimethylsiloxane and the like. When the light-emitting diode 221 emits light, it will penetrate the second liquid, and then pass through the light-transmitting cover 24 〇 and then irradiate it to the external environment. More specifically, ’ 'the refractive index of air is 1, the refractive index of water is about 1.33333, and the refractive index of eucalyptus oil is between 1.390 and 1.410. When the light of the light-emitting diode 221 passes through the interface between the air and the light-emitting diode 221, a large refraction effect is formed, and a larger portion of the light is reflected back into the light-emitting diode 221, thereby losing power. It also produces extra heat. When the second closed space 252 is filled with the second liquid, the refraction effect between the second liquid and the light-emitting diode 221 can be reduced, and more light is emitted from the light-emitting diode 221 to the external environment, in addition to reducing heat. In addition to being generated, it is also possible to reduce the loss of electric energy and increase the brightness of 9 luminescence. Figure 3 shows a schematic view of a lighting device in accordance with another embodiment of the present invention. The illuminating device 200a of the embodiment is similar to the illuminating device 2A of the embodiment of Fig. 2, and therefore the same components are denoted by the same reference numerals, and the related description will be omitted, and the following will distinguish at least one of the two.
