It is used, but due to the general illumination system of the projection lamp, the relative heat dissipation of the high heat source will also cause the illuminator to pass through when it emits light. It is important that in the conventional body: when the heat is emitted, the projection lamp is connected to the outer edge of the lamp cup 4 = = because the outer edge of the lamp cup 40 is only two: arc:: I face, Asia When there is no heat supply for the heat source, the light source 40 transmits the heat source faster than if the light body is guided to the heat dissipation between the lamp cup and the outside air: 2:= 5 M307722 Source hoards in the light In the local position of the body and the lamp cup 4 Q, the phenomenon of poor heat dissipation is caused, and the light-emitting body is liable to be inconvenient to use due to overheating. [New content] Therefore, the main purpose of the present invention is that the required light-emitting unit can be disposed in the lamp cover, and when the light-emitting unit is used, the heat source is absorbed by the lamp cover and the heat dissipation unit is used to dissipate the heat source. In order to increase the heat dissipation area, a better heat dissipation effect can be achieved. For the purpose of the above, the present invention relates to a heat dissipation structure for a lampshade, comprising a lampshade having a lamp cup and an extension, wherein the extension has a perforation, and the lamp cup and the extension on the inner side of the lampshade have a bearing And a plurality of heat dissipating units disposed on the outer edge of the lamp cover, each of the heat dissipating units includes at least one first fin body disposed on an outer edge of the extending portion, and second and third fins respectively corresponding to outer edges of the lamp cup a sheet body, and one end of the second and third fin bodies is connected to one end of the first fin. [Embodiment] Please refer to the "Third, Fourth, and Fifth Diagrams" for the three-dimensional appearance of the creation, the three-dimensional appearance of the other angle of the creation, and the schematic diagram of the profile of the creation. As shown in the figure, the present invention is a heat dissipation structure of a lampshade, which is composed of at least a lampshade 1 and a plurality of heat dissipating units 2, and the required lighting unit can be disposed in the lampshade 1 when used by the lighting unit. The lampshade 1 absorbs its heat source and cooperates with the heat dissipating units M307722•2 to dissipate the heat source, thereby increasing the heat dissipation area and achieving better heat dissipation. The lampshade 1 has a lamp cup 1 1 and an extension 1 2 having a perforation 1 2 1 at one end of the lamp cup 1 1 , and between the lamp cup 1 1 and the extension 1 2 on the inner side of the lamp cover 1 The mounting portion 13 has at least two through holes 133, and a reflecting portion 14 is disposed on the inner edge of the lamp cup 11. Each of the heat dissipating units 2 is disposed on the outer edge of the lampshade 1 , and each of the heat dissipating units 2 includes at least one first fin body 21 disposed on the outer edge of the extending portion 12 and respectively disposed on the outer edge of the lamp cup 1 1 The second and third fin bodies 22, 23 are curved and corresponding to one end of the first and second fins 22, 2, and each of the heat dissipating units The first, second, and third fin bodies 2 1 , 2 2 , and 2 3 have the same height and are provided between the second and third fin bodies 2 2 and 2 3 adjacent to each of the heat dissipating units 2 . A heat dissipating portion 24 having a class Φ plane. For example, the heat dissipation structure of a new lampshade is constructed by the above structure. 〇 Refer to the sixth and seventh diagrams, which are schematic diagrams showing the state of use of the creation and the schematic diagram of the state of use of the creation. As shown in the figure, when used, a light-emitting unit 3 is disposed in the lamp cover 1, and the light-emitting portion 31 provided with the high-power light-emitting body 311 of the light-emitting unit 3 is disposed on the lamp cup 1 1 and the extension portion 1 2 The illuminant 3 1 1 corresponds to the opening of the lamp cup 1 1 , and the connection head 3 2 of the illuminating unit 3 is disposed in the perforation 1 2 1 of the extension 1 2 and is transmitted through Carrying 7 M307722 Part 1 3 through the hole 3 3 with the wire 3 3 and the connection, when using the special purpose 丨丨 、, when the brackets, the mouth first P 3 1 electrical connection (Figure = head 32 and external The docking socket is electrically connected (not shown), so that the connector 3 is used, and the illuminant 3 i is placed on the illuminating body 3 Γ to enable the light source 3 to emit light. The light source emitted by the body 3 ii is also generated with a high heat source, and when the heat source 2: ^^ stretches the segment 2 2 while absorbing the operation of the light-emitting unit 3, the heat source is transmitted to the first of the heat-dissipating units 2 , 2nd and 3rd, 2 2 2 3 and the heat dissipating part 4 4, so that the majority of each emission = 2 exchanges heat with the outside air, and the heat dissipation area is increased. X-ray early 3 produced the effective dissipation. In summary, the heat dissipation structure of the present lampshade can effectively improve the shortcomings of the conventional use, and the required light-emitting unit can be placed in the lampshade, and the light-emitting element is Use &^' to use the lampshade to absorb its heat source port and cooperate with the heat dissipating units to dissipate the heat source to increase the heat dissipation area and achieve better heat dissipation effect, thus making the creation of this creation more progressive and practical.
