Description

M266545 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to the heat dissipation structure of an LED lamp. The heat source generated by the lamp group is transmitted to the lamp j through a heat pipe to achieve effective heat source dissipation. [Prior art] It is known that currently, light emitting diodes have many advantages such as cheaper prices than traditional light bulbs, so light emitting diodes are used on flashlights. Due to the light bulbs produced by a single light-emitting diode, the user usually uses a plurality of light-emitting diodes to increase its light-emitting brightness, so that it can be changed. However, because the light-emitting diode system is used to increase electricity and efficiency, so Then it faces the problem of rising with the increase of current. Although the light-emitting diode system can be heated, but because the circuit board is a single board made of mostly metal, it has only two ends. There are many electrical components that release heat, which makes the circuit board's thermal conductivity coefficient low, and Shaanxi Quick Transmission 'is dissipated to the outside world. Therefore, it does not meet the needs of body heat dissipation, so that the high-power light emission is used as power. Can't improve. [New content] The main purpose of this creation is, especially, a type that allows external heat dissipation on LEDs. It is lightweight, energy-saving, and is used in lamps or less than a traditional lamp body soldered to a circuit board. Good lighting is insufficient. The lack of current and quantity can improve the heat dissipation of the high-power light-emitting diodes, which can be dissipated by PCB or ceramic materials at both ends of the circuit board with local heat overheating, and its electronic components such as capacitance and resistance.
