New description: [New technical field] This creation is related to a kind of light-emitting diode (10)) lamps, especially an LED lamp with flat-plate heat pipe soaking. [Prior Art] • High-power light-emitting diodes (LEDs) are prone to generate a large amount of waste heat when they emit light. Especially when a centralized chip is used, a large number of (10) wafers are densely placed on the substrate. Difficult to discharge. If the LED lamp has no good Yuqing, the LED crystal temperature will be too high, which will greatly reduce the performance and life of the LED. For example, the harvesting fan is made of wire, although the heat dissipation capability is strong, but it involves noise and fan life, especially when the fan fails, the LED will overheat and burn out quickly; if passive heat convection is used, It can be quiet and has no life limit, but the natural convection heat dissipation performance is very low, and it needs to be matched with a large area of heat transfer fins to cope with a large amount of waste heat. Moreover, since a large amount of waste heat is concentrated and is not easily dispersed uniformly on a large-area heat-dissipating Korean film, in order to avoid the difficulty of soaking heat, a distributed design is widely used, and a large number of wafers are spread over a large area to avoid excessive concentration of heat, which is natural. Control the LED (9) temperature under convection conditions. However, the decentralized design is much more complicated than the centralized design in terms of circuit configuration, waterproof processing, and light control. 3 M416028 The creator has previously proposed the Republic of China Patent Application No. 98128179, which discloses a technique for centralized high-power LEDs. As shown in Figure 1, a flat heat pipe 112' with uniform heat is used and placed in one. The sealed container wall 110 is formed in an airtight space. Further, a sealing substance 134 is provided around the joint surface of the substrate 131 of the LED module 130 (including the LED chip, the LED substrate, the light-transmitting mirror, and the like) and the bottom plate of the sealed container wall 11 to seal the LED substrate 131. In addition to the function of uniformly dispersing the waste heat energy to a large area, the large-sized heat dissipation fins 126 can fully exert the function of passive heat dissipation, and the flat heat pipe 112 and the substrate 131 of the LED module are subjected to the sealed container wall 110. The sealing material 134 is sufficiently protected from water or contaminants in the environment and has the advantage of being free of rust. However, in this prior art, the LED substrate 131 and the flat heat pipe 112 are separated by the sealed container wall 110 'so that the heat conduction path between the two includes a layer of the container wall 11 〇 and the two layers of the thermal interface material 138 ', resulting in an increase in thermal resistance. , has a negative impact on the temperature control of led. [New content] In order to solve the above problems, the present invention proposes a light-emitting diode lamp in which a flat-plate heat pipe and a (10) chip system are disposed in an air-tight space of waterproof and anti-steam. The new zone borrows the layer thermal interface f' directly to the substrate of the LED chip, and the cold surface of the flat 4 heat pipe is directly connected to the heat sink Korean substrate by the other layer of the thermal interface. The heat released by the (10) chip can be diffused to the A-area by means of a high-heat-heated plate heat pipe, and then dispersed to the outside air towel, which has the advantage of high heat dissipation efficiency, so that the LED crystal# The temperature scale is at a lower temperature. In addition, the flat heat pipe and the LED chip are fully protected by the airtight space, and are isolated from water or contaminants in the external environment, and have the problem of being free of rust buttons or performance degradation. In order to achieve the above object, a light-emitting diode lamp according to an embodiment of the present invention comprises: an air-tight space, which is composed of a frame, a part of a heat-dissipating fin structure bottom plate, and a light-transmitting mirror, wherein at the joint surface of each component Place the clamping elements, such as the 〇-ring or gasket ring, to prevent leakage and complete the assembly and fixing with the locking elements. The airtight space includes at least one light emitting diode chip and a flat heat pipe. The lower surface of the flat heat pipe is adhered to the substrate of the light emitting body by a layer of thermal conductive interface material, and the upper surface thereof is borrowed by another thermal interface. The substance adheres to the bottom plate of the heat dissipation fin structure. [Embodiment] FIG. 2 is a schematic structural view of an LED lamp according to an embodiment of the present invention. As shown in the figure, an LED lamp 5 is composed of at least one LED chip 15, a flat heat pipe 12, a heat sink fin structure 24, and a heat sink fin structure. The frame 16 and a transparent mirror 14 are provided with openings in the outer ring of the mirror 14 and the locking element 18 is directly inserted through the opening to eliminate the necessity of the fixing frame 17. The flat heat pipe 12 is a sealed cavity containing a small amount of working fluid (not shown). The inner wall of the cavity is usually attached with a capillary structure (not shown) and defines an evaporation zone. The evaporation zone refers to a region where the flat heat pipe 12 and the substrate of the LED chip 15 are adhered; the waste heat generated by the LED chip 15 is transmitted to the evaporation zone of the flat heat pipe 12 via the first heat conduction interface material 36, so that the work there is performed. The fluid absorbs the heat of the heat source to become steam, and the steam is uniformly diffused inside the pipe body and further condensed in a large area of the condensation zone, where the condensation zone is the area where the flat heat pipe 12 and the heat dissipation fin structure bottom plate 25 are adhered; The second heat-conducting interface (10) released by the condensation is transmitted to the heat-dissipating Korean structure bottom plate 25, and then dispersed to a large area for heat dissipation, and then convected by natural convection to the outside air towel. The thief sheet structure 24 can be suitably surface treated, such as anodized, coated, or otherwise, to increase heat radiation. The heat dissipation fins 26 may also have uneven surfaces, such as waves, to enhance the heat dissipation effect of natural convection. The above (10) luminaire 5 can cover more than one independent airtight space 1 〇 'individually include - flat type heat pipe ι2, one (10) chip 15 and - light transmissive mirror 14 and the like; can also cover more than one large independent airtight 1G, the side includes a plurality of (10) other 15 or a plurality of flat heat pipes 12. Since the LED chip needs to be connected to the power supply line, the above-mentioned airtight space 10 needs a power supply line, as long as the power supply line through hole (not shown) 7 M416028 is well protected against leakage, such as using a screw, an annulus or a sealing substance. The airtightness of the airtight space 10 can be easily maintained. In addition to being watertight and airtight, the above disclosed structure also has the convenience of being easy to install and disassemble. FIG. 2 also discloses that a plurality of ventilation through holes 27 may be disposed in the heat dissipation fin structure bottom plate 25 to facilitate the cold air flowing under the LED lamps 5 to flow upward through the through holes 27 into the gap of the heat dissipation fins 26 to enhance the heat dissipation capability. FIG. 3 is a schematic structural view of a light-emitting diode lamp according to another embodiment of the present invention, which includes a power controller 7〇 for supplying the LED chip 15 (the power line is not shown); a lamp cover 6〇 A plurality of shade ventilation openings 61 are provided thereon for facilitating the circulation of the convective gas floating upward. The above-mentioned Shi Guanjian is a description of the technology of this creation. The purpose of the technique is to enable those who are familiar with the art to understand the implementation of the creation and to implement the patent. Changes or modifications to the scales made by the spirit of this work should still be covered by the scope of this creation. 8 M416028 27 Through Hole 36 First Thermal Interface Material 38 Second Thermal Interface Material 60 Lampshade 61 Shade Vent Opening 70 Power Controller
