New Description: [New Technology Field] [0001] The present invention relates to a lighting device, and more particularly to a bulb type light emitting diode lamp and a heat dissipating structure thereof. [Prior Art] [0002] Generally, a tungsten filament bulb uses a tungsten wire as a light source, and has a simple structure and is convenient to install and replace. The structure of the tungsten filament bulb is usually fixed at the end of the spherical bulb, and the rotation is turned. The joint has a thread for screwing into a general 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, thereby achieving the purpose of illumination, but in the tungsten bulb During the operation of generating illumination light, a large amount of heat energy is also generated, so that power consumption and energy are wasted, and the crane 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. The light-emitting diode has the characteristics of small volume, low driving voltage, fast reaction rate, shock resistance and long life. With the continuous development and advancement of technology, the electronic components are required to be light and thin, so that the bulb-type LED lamps gradually replace the tungsten bulbs and become a large-scale and widely used lighting device. [0004] A conventional bulb-type light-emitting diode lamp mainly includes a circuit board, a plurality of light-emitting diodes electrically connected to the circuit board, and a light-transmitting cover covering each of the light-emitting diodes. An aluminum extruded heat sink to which the circuit board is attached, and a joint fixed to the aluminum extruded heat sink; however, because the heat dissipation efficiency of the aluminum extruded heat sink depends on the surface area thereof, Form No. A0101 Page 3 of 17 M383699 The surrounding gas can only exchange heat on the surface of the aluminum extruded heat sink, so the heat dissipation effect is limited and the heat dissipation rate is slow, which in turn affects the bulb type LED lamp. Work efficiency. [0005] In view of this, the present creator has focused on the above-mentioned prior art, and has devoted himself to researching and using the theory to try to improve and enhance the performance, and finally proposes a design that is reasonable and effective. [New Content] [0006] The purpose of this creation is to provide a bulb-type light-emitting diode lamp and a heat-dissipating structure thereof, which can enhance heat convection and thereby improve heat dissipation efficiency. [0008] In order to achieve the above object, the light bulb type LED lamp comprises: [0008] a heat dissipation structure comprising a heat conducting plate and a plurality of heat sinks bent upwardly from a periphery of the heat conducting plate, and the plurality of heat sinks The heat sinks are spaced apart from each other; [0009] a light emitting diode module is attached to the bottom surface of the heat conductive plate; and [0010] a lamp cap, the heat sink is sleeved and electrically connected to the light emitting diode module [0011] In another technical means for achieving the above object, the light bulb type LED lamp has a light emitting diode module, and the heat dissipating structure comprises: [0012] a heat conducting plate, the bottom surface of which is used for the light emitting The diode module is attached; and [0013] a plurality of heat sinks are bent upwardly from the periphery of the heat conducting plate, and the heat sinks are spaced apart from each other. [0014] The effect of the present invention is that the ambient gas can freely turbulently exchange heat between the heat sink sheet number A0101, page 4/17, M383699, to enhance the heat dissipation effect of the heat convection and make the heat dissipation rate faster. Furthermore, the working efficiency of the bulb-type light-emitting diode lamp is improved, and the heat-dissipating structure uses less material, which can reduce the manufacturing cost and reduce the overall weight, and is quite economical.

However, the light-transmitting lamp cover 300 has a spherical shape, but is not limited by this shape. A diffusing layer (not shown) is formed on the light cover 300. The diffusing layer converts the direct light of the light emitting diode 220 into wide-angle diffused light to increase the overall illumination range. [0023] The lamp cap 400 includes a converging member 410, an electrical connector 420, and a hollow tube 430. [0024] The converging member 410 is made of an insulating material, such as plastic, but not in the form of a material. No. A0101, page 6 / page 17 M383699 is limited. The circumference of the receiving member 41 0 is provided with a ring groove 411. The ends of the heat sinks 120 are respectively embedded in the ring groove 411, and the receiving member is respectively The heat dissipating structure 100 is more stable, and the heat dissipating fins 120 are gradually contracted toward the converging member 410 by the heat conducting plate 110, thereby reducing the overall volume of the bulb. A uniform hole 412 is defined in the center of the converging member 410 for the first conductive wire 230 and the second conductive wire 240 to pass through. The electrical connector 420 is formed in a cup shape, and an end portion 421, an insulating portion 422, and a screwing portion 423 are formed on the electrical connector 420, and the end portion 421 and the screw portion 423 are The conductive material is made of, for example, metal, but is not limited by the material. The outer periphery of the screw portion 423 is formed with a thread for screwing into a general bulb holder. The insulating portion 422 is formed at the end portion 421 and The screwing portion 423 is configured to insulate the end portion 421 from the screwing portion 423. The electrical connector 420 is fixed to the converging member 410 by the screwing portion 423. The first conductive wire 230 is electrically connected to the end portion 421, and the second conductive wire 240 is electrically connected to the screw portion. 423. [0026] The two ends of the hollow tube 430 are respectively inserted into the through hole 111 and the through hole 412, and the hollow tube 430 has a through hole 431 for the first conductive line 230 and The second conductive wire 240 is disposed therein, and the hollow tube 430 can converge the first conductive wire 230 and the second conductive wire 240 to provide a protection function, and the outer portion of the hollow tube 430 is provided with a plurality of grooves. The groove 432 is used to increase the surface area of the hollow tube 430, thereby improving the heat dissipation effect.

The first conductive line 230 and the second conductive line 240 form a current loop, and the light-emitting diodes 220 are energized to emit light. During operation of the light emitting diode 220, the light emitting diode 220 and the circuit substrate 210 simultaneously generate heat, and heat is transferred from the light emitting diode 220 and the circuit substrate 210 to the heat conducting plate. 110. The heat conducting plate 110 further conducts heat to the heat sink 120 and the hollow tube 430. The heat sink 120 and the hollow tube 430 exchange heat with the surrounding cold gas respectively, thereby emitting the light emitting diode. 220 and heat generated by the circuit substrate 210. [0029] Due to the gap between the fins 120 and the hollow space enclosed between the fins 120 and the hollow tube 430, the surrounding gas can be effectively convected therebetween, so that the heat is heated. The convection effect is accelerated, thereby improving the heat dissipation efficiency, and the material of the heat dissipation structure 100 is less used, which can reduce the material cost and reduce the overall weight, and is quite economical.
