Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention is a lighting device. [Prior Art] Patent EP 2025 999 refers to a lighting device in which the air for the device is discharged from the side through the air holes outside the lighting device. A heat retreat of the outer casing and the lighting device. SUMMARY OF THE INVENTION It is an object of the invention to provide a size (especially; small illumination device. According to at least one embodiment of the illumination device, at least one light-emitting diode wafer is illuminated. The illumination device is preferably a photodiode wafer. For example The active light-emitting diode has a spectral range between infrared and ultraviolet light. The wafer constitutes a light source of the illumination device and generates light from the illumination device. According to at least one embodiment of the illumination mode, a cooling body is cooled. The body may have a plurality of fins. The fins are disposed on an outer surface of the heat sink and the outer surface is enlarged. Therefore, the heat sink can be discharged to the surrounding environment via its outer surface. For example, the heat sink and its plurality of discrete bodies are formed. Another possibility is to fix the heat sink on one body of the heat sink instead of forming the heat sink body. The cooling heat sink in the illuminating housing is in a volume of each other. The device has a plurality of wafers.

The outer casing houses at least a majority of the components of the gg #胃_I %Y month device, such as an AL* Μ々 ^ of the light-emitting diode wafer or the heat sink. The housing is partially enclosed by the lighting device. In other words, the county force, that is, the outer surface of the outer casing facing the cooling body constitutes at least eight of the outer surface of the lighting device. According to at least one of the lighting methods. The lithography method forms a thermal contact between the luminescent diode and the heat sink. For example, J is used to directly place the first diode on the heat sink. Another way of <RTI ID=0.0>>>"""""""""""" The one side of the body forms an electrically conductive connection. In either case, the light-emitting diode wafer is thermally connected to the heat sink, so that the heat generated by the operation of the light-emitting diode can be absorbed by the heat sink. According to at least one embodiment of the illumination mode, the outer casing surrounds at least a portion of the heat sink from the side. That is to say, the outer casing surrounds the heat sink from a lateral direction, for example, the transverse direction perpendicular to the main radiation direction of the light generated by the light-emitting diode wafer. The outer casing can surround the heat sink from the side, so that the side of the heat sink The outer surface will be surrounded by the outer casing. A good way is that there is no lateral opening on the outer casing towards the heat sink. Thus, at least the side of the heat sink is entirely surrounded by the outer casing. According to at least one embodiment of the illumination mode, at least a portion of the fins extend in the direction of the outer casing. That is, the heat sink has a face facing the outer casing and a face facing away from the outer casing. The heat sink has an end face on the face facing the outer casing, and at least a portion of the heat sink 201239257 is in thermal contact with the outer casing on the end face. For example, a heat conductive material may be disposed between the end face and the outer casing. In particular, the space in which the thermal contact is formed between the front side and the outer casing cannot exist in the presence of a gas such as air. A particularly advantageous way is that the end faces are in direct contact with the outer casing at the point of thermal contact. That is, at least a portion of the end face of the heat sink >; contacts the outer casing. In this way, a particularly good thermal connection from the heat sink via the heat sink to the outer casing and a particularly good heat transfer can be formed. In particular, a contact surface can be formed between the heat sink material and the outer shell material without separately providing a material for contact at the location of the thermal contact. The connection between the heat sink and the outer casing can be released in a non-destructive manner. For example, for maintenance work, the outer casing can be separated from the heat sink without causing damage or damage to the components of the lighting device. According to at least one embodiment of the illumination mode, the illumination device has at least one light-emitting diode wafer, a heat sink having a plurality of heat sinks, and an outer casing. The at least one light emitting diode wafer is in thermal contact with the cooling body, for example, all of the light emitting diode wafers of the illumination device are in thermal contact with the heat sink. The outer casing at least partially surrounds the heat sink portion, for example, the entire heat sink, and at least a portion of the heat sink extends toward the outer casing, and at least a portion of the end surface facing the outer casing contacts the outer casing, in particular direct contact. Through the thermal connection of the heat sink to the outer casing, the area of the illuminating device that dissipates outward is expanded. The degree of expansion corresponds to the area of the outer casing. The expansion of the 11 areas can improve the cooling effect, including passive cooling, as well as the cooling effect between the air surrounding the illuminator and the surface outside the outer casing. At least a part of the heat sink and outside. 201239257

For example, the heat sink and the outer casing are made of a good thermal conductivity, such as a metal. When the lighting device is in operation, the cooling body and the outer casing have substantially the same temperature due to the temperature compensation through the heat sink, and the convection can improve the passive cooling of the outer casing because of the relatively hot outer surface of the casing. Exchange heat with the surrounding environment. The size of the illuminating device of the present invention (especially in the body) is the size of the pre-existing illuminating device since the outer casing is expanded to the extent that the solar irradiance is sufficient. Several areas of the illumination device of the present invention can be used for cooling. According to at least one embodiment of the illumination mode, the illumination device has a ventilation duct. These air ducts extend in the outer casing and the heat sink of the lighting device. When the lighting device is in operation, cold air for the cooling body and the outer casing flows through the air passage. At least a portion of the air ducts (e.g., at least 90% of the air ducts, or extremes of all air ducts) are confined from the side (i.e., lateral) by two adjacent fins and outer casings. In other words, the 'heat sink portion is mechanically coupled to the outer casing' while forming an empty flow passage through the outer casing and the cooling body. This air flows through the cooling body and the outer casing facing the surface of the cooling body, thereby cooling the cooling body and the outer casing. Air flow through the air duct through the air duct. An air pressure can be induced by natural convection and/or a fan. 201239257 This difference in air pressure will increase or drive the air flow through the air duct. At least a part of the side of the air duct is surrounded by the fins and the outer casing of the cooling body, so that the cooling air passing through the air passage can exchange heat through a large area of the lighting device. Since the thermal connection and the mechanical connection between the cooling body and the outer casing are the same heat flow in the area of the outer casing and the cooling body surrounded by the air, the air flowing around is uniformly cooled. Since the external limbs enlarge the area available for cooling, the speed of the potassium air flow can be relatively small compared to the conventional ‘. If you have a fan, you can also reduce the size of the fan and / or use a fan with less power. In this way, the size and/or manufacturing cost and/or energy consumption of the lighting device can be reduced compared to conventional lighting devices. According to at least one embodiment of the illumination mode, the heat sink has a gap for accommodating at least one of the light-emitting diode chips: That is to say, the heat sink can have a hollow portion. The light-emitting diode wafer of the illumination device can be disposed in the hollow portion of the heat sink. In this way, the light-emitting diode wafer of the illumination device can also be surrounded by the side (i.e., in the lateral direction) of the heat sink. In this way, the heat sink can absorb a large amount of heat energy from the operating light-emitting diode. In addition, for the light emitted by the light-emitting diode during operation, the heat sink facing the inner surface of the light-emitting diode wafer can assume the optical characteristics of the reflector. For example, the gap can be placed on a body of the cooling body. In at least one embodiment of the known method, the heat sink has a body, wherein at least a portion of the fins extend from the heat sink toward the outer casing at least at certain locations, wherein at least a portion of the air passages are covered by two The adjacent heat sink, outer casing, and body of the cooling body 201239257 are restrained from the side. Shijia, a large 4 points heat sink, that is, more than 50% of the heat sink or all of the I μ u, the monthly hot film (extreme case) is the case. The body of the cooling body and the bulk H-r", the sheet may be integrally formed. In this case, the mechanical connection and the thermal connection of the sleeve ί u between the body and the heat sink are particularly good. 1 less-type embodiment, the outer casing surrounds the cold body from the side, and most of the fins are at least partially located outside the squat and the limbs are in direct contact. That is, in this case, there are 50% The above heat sink (for example, 940% or more of the heat sink) is at least partially positioned 1 and the outer pole body is in direct contact. An advantageous manner is that the contact surface between the heat sink and the outer body is particularly large. For example, 'each A majority of the area of the heat sink facing the end face of the outer casing is in direct contact with the outer casing. According to at least one embodiment of the illumination mode, at least a portion of the air passage extends along most of the heat sink. For example, heat dissipation of the heat sink The sheet extends in a direction perpendicular or oblique to the lateral direction. For example, the heat sink has a main extension direction in the main radiation direction of the light emitted from the light emitting diode wafer. A rare portion of the position extends in the main extension direction of the heat sink. The fins that limit the extent of at least a portion of the air passages preferably extend at least 50% of the length of the body of the heat sink such that at least a portion of the air passages can follow Most of the cooling body extends. In this way, it is ensured that the cooling body can achieve an effective cooling effect. According to at least one embodiment of the lighting method, at least part of the body of the cooling body is shaped into a round body and/or Or a flat-headed cone shape in which at least a portion of the fins extend at least partially along the outer contour of the cylinder and/or the frustum of the cone. The so-called "cylinder 201239257 body and / or frustum cone" The shape does not mean that the shape of the body must conform to the shape of a mathematically defined cylinder or flat-headed cone, but rather that the outer surface of the body has at least a portion of the paragraph that is very close to such a shape. A common cylinder. The frustum cone can be a common frustum cone. The so-called ordinary cylinder means The bottom surface is not necessarily a circular cylinder, that is, the bottom surface may be any shape. The ordinary cylinder may also be a tilted or sinuous cylinder 'that is, the bottom surface is not directly above the top surface, but There may be a displacement. The above description also applies to a conventional frustum cone. For example, the body has a gap for a light-emitting diode wafer that can accommodate the illumination device. According to at least one embodiment of the illumination mode, the illumination device has a light output side having two light output faces thereon. At least one (preferably a majority) of the light emitted by the at least one light emitting diode chip exits the illumination device through the light output face. A particularly possible The situation is that all of the light generated by the illumination device exits the illumination device through the light output face. The light output face can be located on the light output side of the illumination device within a larger outer surface of the illumination device. Further, at least one vent hole on the light output side of the illuminating device can discharge the illuminating device through the vent hole or the air can be drawn into the ventilating passage through the vent hole from the outside. That is to say, 'the air for cooling the cooling body and the body is not discharged laterally through the opening of the body bonfire', but at least a part of the air is separated from the illumination in the opposite direction by -10-201239257. The side devices may not be and the openings may be surrounded. They are also spaced apart from each other by one or more depending on the flow, each flowing through * or a ventilation duct. The way in which the illuminating device can be used is one or a plurality of out-of-plane ways to set up a network of light. The air passes through the dust. In accordance with the direction of the light from a fan, the device is discharged from the lighting device or along the lighting device. One feature of the illuminating device designed in such a way is that there is no need for space for venting air in the illuminating surface. Therefore, such illumination is often accurately placed into the opening of the ceiling or wall without the need to provide a space for the discharged air. The way to do this is to have the light output face with two or more venting holes surrounding the light output face such that the venting holes surround the light output, such as a venting hole. Alternatively, several venting holes surround the light transmission surface in a framed manner. In at least one embodiment of the present mode, the venting of the illuminating device is supplied by at least one possible way of venting air from each of the at least one venting air to each of the venting passages. A venting hole is formed on the light output side of the end. Alternatively, a plurality of air passages may be injected into a common venting opening. This venting hole can transmit light on the light output side of the illumination device. For example, this - or a plurality of venting holes can be surrounded by the framed face. At least one embodiment of the formula, each of the vented air-rolling filters, such as a fine mesh plastic mesh or metal receptacle, has the task of absorbing the air into the venting means. In at least one embodiment of the present mode, the fan is located on the side of the outer casing that faces the side of the light wheel illumination device -11 - 201239257. The task of the fan is to force air to flow through the air duct to the light output side or to draw in air from the light output side. When air is directed to the light output side, air can escape on the light output side through at least one venting hole. When the fan draws in air from the light output side, the air escapes from the side of the illumination device that faces away from the light output side. According to at least one embodiment of the illumination mode, the fan has a rotor having a rotational axis that leads to the light output face at a non-perpendicular angle. In other words, the fan does not have to be located directly above the light output surface, but the outer casing < is curved, so the rotating shaft of the rotor is illuminated to the angle of the tilt (extremely the year "lights) The light output side of the device. Designing the outer casing into a curved shape helps to reduce the construction height of the lighting device. Since at least a portion of the air is driven by the fan or drawn into the air passage, the air is guided to flow along the outer surface of the heat sink and the inner surface of the outer casing. Therefore, although the outer casing is designed to be curved, there is little or no area on the heat sink & outer casing that is significantly higher in temperature than the outer casing or other locations of the cooling body. That is to say, due to the structural relationship of the air passages, even if the outer casing is curved, a very uniform cooling can be achieved. [Embodiment] The lighting device of the present invention will be further described below in conjunction with the embodiment and the drawings. . Fig. 1A is a plan view showing in a schematic manner. Figure 1 B shows the photo. The illuminating device has a three-dimensional body 2 of an embodiment of a horizontal section of the cold illuminating device. The heat sink 2 has a body 2012's body 22'. In this embodiment, the outer surface of the body 22 is shaped like a frustum of a cone. A fin 21 integrally formed with the body 22 of the heat sink extends along the outer contour of the frustum of the cone. The fins 21 extend from the body 22 toward the outer casing 3, wherein the outer casing 3 surrounds the heat sink 2 entirely from the lateral direction 1. The fin 21 faces the inner surface of the outer casing 3 facing the end face 2 10 of the outer casing 3. Most or all of the end faces 21 of the fins 21 are at least partially in contact with the outer casing 3. The outer casing 3 and the heat sink 2 are mechanically connected to each other via a fixing member 5, for example, the fixing member 5 may be a screw, a fixing pin or a bolt. The heat sink 2 (that is, the body 22 of the heat sink 2 in this embodiment) has a gap 23 for accommodating the light-emitting diode wafer 1 as a light source of the illumination device. The light-emitting diode chip 1 is disposed on a connection carrier '. For example, the connection carrier is a printed circuit board that is fixed on the mounting surface 24 of the heat sink 2 in the gap. The gap 2 3 faces the light-emitting diode chip. The inner surface of 1 can reflect the electromagnetic radiation emitted by the light-emitting diode wafer 1 so that the gap 23 can function as a reflector. Further, an optical element, such as a lens, not shown in the drawings, may be provided in the gap 23 to function to shape the light emitted from the LED wafer 1. In addition, the illuminating device further has a fan 7 disposed on the surface of the illuminating device facing away from the light output side 6, which functions to drive the air 4 1 to flow through the cooling body 2 and the outer casing 3, or to suck in air. . This air is guided through the air duct 4 at least in part. Figure 1C shows an enlarged view of the air duct 4. The range of the air passages 4 is restricted from the side by the adjacent heat radiating fins 21, the outer casing 3, and the body of the heat sink 2. -13- 201239257 The air 4 1 for cooling the outer casing 3 and the cooling body 2 flows through the air passage 4 to the outer casing 3 and the cooling body 2. Fig. 1D shows a perspective view of the heat sink 2 in which the heat sheet 21 is not provided on the body 22, wherein the air passages 4 are formed between the fins 2 1 . When the lighting device is in operation, due to the thermal connection between the cooling body 2 and the outer casing 3, that is, the end surface 210 of the fin 21 is in contact with the outer casing 3, the temperature of the cooling body 2 is lower than that between the outer casing and the outer casing. The temperature of the body is reduced by about 25 %. The reason why the temperature is lowered is because the area of heat exchange with the surrounding environment becomes large. Therefore, the product of the lighting device can be correspondingly reduced. The illumination device cooling will be further described below in conjunction with Figures 2A, 2B and 2C. As can be seen from the perspective view shown in Fig. 2A, the fan 7 has one less rotor 71 that rotates about the axis of rotation 72. The fan draws the air 41 into the interior of the illuminating device, i.e., is pumped to the outside by the outer casing 3, and drives the air 41 to flow through the venting passage 4 toward the light transmitting side 6 of the illuminating device. Although the outer casing 3 in Fig. 2A is a bending test, that is, the rotary shaft 72 does not vertically lead to the light output side 6, in this manner, a uniform flow of the body can be formed in the lateral direction. The hot sheet 21 is to introduce air into the air passage 4 via the top surface of the body 22 of the heat sink 2 facing away from the light output 6, or to discharge the air through the passage 4 (see Fig. 1D). Furthermore, it is possible to design the cooling body facing the top surface of the fan 7 in a domed dome shape. That is, the body 22 has a convex curvature at it. This design improves the flow of air 41 across the entire outer surface of the heat sink. Fig. 2B is a flow diagram of the current flow of the cold surrounding body to the outgoing side wind of one embodiment of the simulated lighting implementation. The arrow 41 is representative of the air flow. It can be seen from Fig. 2b that 'there is an air flow formed around the device, that is to say, an air flow is formed around the outer casing 3 against the outer surface of the heat sink 2, and this air flows around the outer surface of the illumination device. The flow contributes to the cooling of the lighting device. The temperature of the outer casing 3 is substantially equal to that of the heat sink 2, which is very advantageous for the cooling of the lighting device. The resulting free convection also contributes to the cooling effect of the lighting device (compare Figure 2c). Unlike the operation modes shown in FIGS. 2A and 2B, the operation mode of the fan 7 may be such that the intake air 41 passes through the air passages 4. The air 41 is then discharged from the fan 7. One advantage of this mode of operation is that it becomes easier to clean the lighting device when sucking air 4 from a space to the lighting device. That is, it is only necessary to remove the dust from the vent hole 42. Alternatively, the air filter may be placed before the ventilation or on the vent 42. If the air 41 is blown into a space from the light output side 6, the ash = product of the insulating material of the ceiling fixed therein is disposed: the opening of the fan 7 is blocked, and the fan is blocked. The illuminator is removed from the ceiling. To the 3C system display, the stereo perspective. In the case of the light-emitting diode wafer i of another embodiment of the device, a device 6 is provided. The light wheel exit surface 61 is surrounded by the vent hole 42 at the position 41 of the ventilating passage 4 at the portion of the light exiting surface 61. The illusion is rolled through the reading female ^ or the air 41 through the through hole 在The aperture 42 is blown away from the illumination device, and the air enthalpy 42 is drawn from the surrounding environment. That is to say, the chaos does not have to be on the side of the horizontal, but also the pillows. It is released from the opening in the outer casing 3 -15-201239257. The illuminating device is also housed in a cavity internal patent PCT/CN for the purpose of fixing the cooling effect described above. In particular, the reduction in size is correspondingly reduced. The other housing is designed to be curved, and the novel features of the present invention, which are poorly cooled, and the ranges mentioned in the respective scopes, even if these descriptions partially or implement the priority of the present application. [Simple description of the figure] The first and second parts of the components of the first and the first 1B, 2A, 2B. Figures 3A and 3B. There is a fixture 8 that functions to mount the lighting device, for example, in a wall or ceiling. For example, the country 2010/079569 (see DE 102009057443.3) further description of the device. The design of the lighting device can greatly enhance the lighting fixture, thus further reducing the size of the lighting device. Similarly, the size and/or power of the fan may have the additional advantage that the venting passage allows for the outer curved shape of the illuminator without causing a position on the heat sink or outer casing. The circumference is not limited to the above embodiments.
