Abstract

The utility model relates to an LED lamp with a good heat-radiation structure, which comprises the LED lamp and a PCB (Printed Circuit Board), wherein the PCB is provided with a through hole, a heat-radiating convex column is arranged on the bottom surface of the LED lamp, and the heat-radiating convex column directly contacts the heat-radiating module of the LED lamp after penetrating through the PCB. The heat emitted by the LED lamp can be directly transferred onto the heat-radiating module to be emitted. The ordinary PCB is adopted to replace an aluminum baseplate in the utility model, the PCB is provided with the through hole, the heat-radiating column of an LED penetrates through the hole position of the PCB when in assembly, the heat is directly conducted to an external heat-radiating body for radiation, and the combined structure not only saves energy sources, but also saves the cost.

Description

A kind of LED lamp with good heat radiating structure

Technical field

The utility model relates to a kind of LED lamp, relates in particular to a kind of LED lamp with good heat radiating structure.

Background technology

Along with the utilization of large-power light-emitting diodes in illumination is more and more general, the overheated meeting of large-power light-emitting diodes has a strong impact on the service life of light emitting diode and the drawback of light extraction efficiency also highlights.

Heat dissipation type high LED lamp has now become widely used illuminating equipment, and it has, and light efficiency height, life-span are long, low power consuming and advantage such as easy to use.The LED lamp of at present a lot of manufacturer production, the radiator structure complexity of light fixture and cost height; The aluminum base plate that must adapted can dispel the heat could and outside radiator heat conduction.

The utility model content

The utility model corrects at above-mentioned problems, makes product structure simple, and material consumption is few; Have the radiating efficiency height, long service life, characteristics such as reasonable in design, thereby, have good value for applications.

Concrete technical scheme is:

A kind of LED lamp with good heat radiating structure, it comprises LED lamp and pcb board, and described pcb board has perforation, and there is the heat radiation projection described LED lamp bottom surface, and described heat radiation projection directly contacts with the radiating module of LED lamp after passing described pcb board.The heat that the LED lamp sends can directly pass to distribute on the radiating module and come.

It also comprises heat conductive isolation sheet, and described heat conductive isolation sheet is between the radiating module of described LED lamp bottom and described LED lamp.The heat that the LED lamp sends can distribute by radiating module and come.

The utility model adopts common PCB to replace aluminium base, and perforation is arranged on the PCB, and the thermal column of LED passes the position, hole of PCB during assembling, and directly heat conduction distributes for outside radiator. and this combining structure is energy savings but also save cost not only.
