New description: [New technical field] This creation is about a heat sink structure, especially an LED heat sink structure. [Prior Art] With the rapid development of the economy, the consumption of energy has increased rapidly, and the problem of tight supply of electricity in many areas has led to the generation of measures to turn off power supply. At this time, it is even more acute. It is an irreversible trend to replace the existing rigs with LED luminaires. In addition to the quantum efficiency wafer size (light-emitting area) and output power of the LED chip, the factor of the luminous output of the LED lighting device is another important factor: the heat dissipation capability.

The luminous efficiency will decrease significantly with the increase of temperature, and the life expectancy will be significantly shortened and the wavelength and forward M(10) drift. Therefore, in order to avoid the adverse effect of heat on which wafers, the heat reading structure of each chicken 镰 LED lamp is reduced, such as the injection-formed Korean sheet heat sink ϋ 'but it is not only high in production cost, but also higher in process system and unit price. There is no problem with the unidirectional arrangement of heat dissipation. In addition, this record (4) is not adjustable after the shape of the finished product, and the wire is required to be used in the design. As a result, different LED lamps cannot be manufactured, and it is impossible to adjust the space in which the LED lamps are installed, which in turn causes a problem of waste of resources for replacing the heat sinks and a problem that consumers are not easy to replace the LED heat sinks when replacing the lamps. In view of this 'this creation 遂 for the lack of the above-mentioned conventional technology, (four) a new LED 3 M366882 heat sink structure 'to give led ρ from the pill / w, TD good heat dissipation effect, and the creation of the coffee heat sink The LED light-emitting element group is further provided with the advantage of a secret replacement. [New content] The main purpose of this creation is to provide a kind of coffee heat sink structure, and its ridge flaps can be adjusted to adjust the size of the LEDs to suit the various lamps. - The absence of a radiator of the corresponding specification. The purpose of this creation is to provide a kind of LED bulk structure, and the bending degree of the thin bending piece provides a multi-directional heat dissipation path, and is used in the same size of the lamp, but can easily add more than double the heat dissipation area. By using the method of bending into the small space of the original LED lamp, the speed of the city heat can be greatly increased, and the temperature of the needle of the LED wk point is reduced, and the effect of the coffee-like dance is doubled. Or double the brightness of the LED under the same life conditions. The re-creation of this creation is to provide a kind of LED scatter structure, which is simple and low-cost. Ten constitutes a radiator for various LED lamps, effectively avoiding the waste of resources caused by the development of various radiators for various lamps. The purpose of this creation is to provide an LED heat sink structure, which uses a tube folding method of the f-fold to install a small LED _, and is equipped with a detachable lamp screw on the hole of the LED heat sink. The utility model has the advantages that the user is easy to loosen the coffee, so as to facilitate the replacement of the entire light-emitting element group when the LED chip bonded to the LED film is broken. To achieve the above object, the present invention proposes an LED heat sink structure comprising a center sheet for carrying at least a foot wafer; and at least a bent sheet connecting the center sheet and extending outward. M366882 is to make the stomach review committee have a better understanding of the structural features and the effects achieved by the stomach review committee.

As shown in the figure, the LED heat sink structure 1G of the present invention includes a ribbed at least-[the central sheet of the ED wafer, which is formed with a plurality of holes M to increase the heat dissipation effect; and eight connected central sheets ^, "Bend of the B-extension"; b' is formed with a number of holes 18 for increasing the heat dissipation effect, and a groove is provided between each adjacent light-folded piece I6. The periphery of the above-mentioned bent piece W The corner is rounded and chamfered to avoid cutting the person. The central body 12 and the bent piece can be integrally formed and are made of a heat conductive material such as aluminum, copper, etc. In addition, a plurality of f-folds 16 can be formed. The outer peripheral corner has a rounded chamfered groove 2〇 to increase the heat dissipation effect, forming a second embodiment as shown in Fig. 2. See also Fig. 3 to Fig. 5, which is the LED heat dissipation of the present invention. Another embodiment of the film is not intended. As shown in the figure, in this embodiment, the fins 16 of the heat sink of the present invention can be bent by the user to show the heat sink of the creation. The appearance is a movable adjustable crane' so it will not be used due to the turning of the luminaire or the space where the luminaire is installed. For example, in conjunction with a luminaire, such as the arrogant lamp 22, the bent piece is bent by the bonding line of the bent piece Μ and the central piece 12, so that the whole coffee heat sink 〇 〇 appears flower-like, shrinking ^ Heat sink Η) (10) degree of inspection '峨 LED LED Lai 1 () can be _ silk in the width of the button is small (four). Of course, the material can be shouted to find the line gently to adapt to the various lamps on the market The original LED is scattered with the material. After the 6th material, the material (4) will form 5 M366882 into the air convection, and the bent piece _-face also provides the way to derive the heat generated by the LED W. Therefore, the LED chip heat dissipation speed is greatly increased. The LED heat sink of the present invention is used in the conventional miscellaneous size reading device, but can lightly (four) more than double the heat dissipation area, and use the bending mode of the green folding piece to enter the LED. In the small space of the luminaire, the speed of heat dissipation is greatly increased, which effectively reduces the temperature of the LED "point of the heart", and achieves a great increase in the life of the LED lamp. Or under the hidden life conditions, multiply the brightness of the coffee. Moreover, as shown in the figure, when the LED heat sink 1 of the present invention is coupled to the luminaire 22, the hole 18 can also serve as a hole for the luminaire to provide a user-level replacement of the LED heat sink. s. When the wafer 12 is bonded to at least one of the LED chips 15, the LED chip 15 and the heat sink structure can be used as the light-emitting element group 17. When the LED chip 15 fails, the luminaire screws 24 detachably locked to the holes 18 also provide the user with a convenient replacement of which of the illuminating element groups 17. Referring to Figure 6, it is a schematic diagram of another embodiment of the present invention. The difference between the embodiment of Fig. 6 and the first is that the bent piece 16 is bent in the form of a blade, that is, not in the manner of riding the joint line of the previous f-foil and the center piece, but The bending is performed at a specific angle with the bonding line of the bent piece Μ and the center piece 12. According to the color, this creation proposes a new LED heat sink structure, which can be used to sculpt the size of the cans by bending the hips ▲, and (4) should be in each cooker, there are ▲ °, single LED The size of the luminaire requires a corresponding type of heat sink missing. In addition, the use of material > {, holes, trenches increase the surface area of the heat sink in contact with the air, increase the way the heat M366882 is dissipated, and also provide a multi-directional heat dissipation by changing the bending of the bent piece. The heat source is accumulated on the LED chip. The LED heat sink structure of this creation is more compatible with the detachable shackle; the lamp screw on the hole of the LED heat sink provides the user with easy to replace the led heat sink or replace the entire LED light emitting component group.
