Description

M435560 V. New Description: [New Technology Field] [0001] This creation is about a heat dissipation structure of a bulb, especially a combined bulb heat dissipation structure that can be tightly combined without the need for screw fixing. [Prior Art] [0002] A conventional bulb uses a tungsten wire as a light source, and has a simple structure and is relatively convenient to install and replace. Tungsten bulbs are typically constructed with a adapter attached to the end of the spherical bulb that has threads for screwing into a typical bulb holder. When the power is turned on, the tungsten wire disposed in the lamp cover can be heated and emitted, and the light penetrates the lamp cover to illuminate the outside to achieve the purpose of illumination. However, during the operation of the tungsten light bulb to generate illumination light, a large amount of heat energy is also generated, which is quite power-consuming, wastes energy, and the tungsten wire is easily burned to make the life of the tungsten filament bulb short. [0003] A light emitting diode (LED) is a solid-state light source that converts electrical energy into light energy, and is fabricated by an epitaxial growth technique and a semiconductor material process. It has the characteristics of small volume, low driving voltage, fast reaction rate, shock resistance, long life and environmental protection. With the continuous development and advancement of technology, its luminous efficiency has been continuously improved since its inception in the 1960s. It has not only surpassed the tungsten filament bulb (efficiency is about 10~201m/W), but it has also been over the fluorescent tube ( The performance is above 60~801m/W). As LED related technologies continue to progress, it is estimated that it will reach the level of 1001m/W in recent years. Since LED has become the focus of the new generation of solid-state light sources, the current demand for electronic components has become lighter and thinner, making bulb-type LED lamps gradually replace tungsten filament lamps and become a large-scale and widely used lighting device. With the popularization of 1〇120557ί single number A0101 page 3/15 pages 1012018219-0 M435560, street lamps, home lighting, car lights, advertising lights, etc., LED has become the mainstream trend in the lighting market. block.

[0004] However, the larger the power 'brightness of the light-emitting diode or its module, the greater the heat generated, and it is difficult to dissipate in a relatively small-sized light-emitting diode lamp. Therefore, the LED has a large heat dissipation technology bottleneck, which is the most difficult point for the marketization of high-power, high-brightness LED lamps. The current common heat dissipation solution in the industry is to provide a heat sink in the luminaire to dissipate heat into the surrounding air by contacting the surface of the heat sink with natural convective air. Therefore, in order to meet the heat dissipation requirements of high-power, high-brightness LEDs for their normal operation to prevent light decay, it is necessary to provide a heat sink with a large heat dissipation area. This generally results in a large volume of the heat sink in the luminaire, and the overall luminaire is also bulky, making the luminaire structure bulky and difficult to use in indoor lighting. [0005] In order to solve the above problem of heat dissipation, the Republic of China New Patent No. M343768 discloses a heat dissipation structure of an LED lamp, and a positioning flange is provided on a periphery of the assembly hole of the outer casing to form a positioning flange. a receiving hole, the two sides of the receiving hole are respectively adhered to the second bonding plate by the first bonding plate, the first bonding plate provides a control wafer setting, and the second bonding plate provides an LED lamp setting, which is disposed with a heat conductive liquid or a thermal grease. The two sides of the accommodating hole are closed by the first bonding plate and the second bonding plate; thereby increasing the contact area of the heat dissipation to increase the heat dissipation effect. [0006] However, the heat dissipating structure of the LED lamp is assembled by screwing and screwing holes, and the first bonding plate and the second bonding plate are assembled in the process, and the device must be added after the mold is opened. When the screw hole is drilled, and the assembly is 10120557^^^^ A〇101 4th/15 pages 1012018219-0 M435560, the screw may be screwed through the screw hole, causing the outer casing to crack. Damage, thus reducing the problem of process yield. [New Content] [0007] The main purpose of this creation is to make the heat dissipating structure assembled with LED lamps only need to be opened once by the structure, and can be assembled and combined to increase the yield and assembly of the process.

[0012] Further, the lamp cover includes a through hole for the LED lamp to pass through. [0013] Further, the first joint portion is a hook groove, and the second joint portion is a hook hooked to the hook groove. [0014] Further, the socket includes a metal joint that connects an external power source to obtain power supply to the circuit board.

[0015] Further, the LED lamp includes a first fitting portion, and the assembly portion includes a second fitting portion that is coupled to the first fitting portion. [0016] Therefore, the present invention sleeves the heat dissipation cover on the sleeve of the lamp holder, and at the other end, the lamp holder is assembled on the sleeve, so that the heat dissipation cover passes through the first abutment on the sleeve. The portion and the second abutting portion of the lamp holder are respectively clamped by the two ends, so that each component of the creation is tightly coupled through the assembly mechanism on the assembly.
