Description

A kind of LED lamp

Technical field

The utility model patent relates to lighting field, relates in particular to a kind of LED lamp

Background technology

Characteristics such as the LED lighting tool has that colourity is good, non-maintaining, the life-span is long, in the energy more and more nervous today, the characteristics of LED lighting meet the requirement of future development.But because technical reason, the LED caloric value is big, and heating is having a strong impact on light decay and the life-span of LED, so the applying of LED, heat radiation is the key technology that must resolve, is restricting the development of LED.Existing on the market LED lamp is many with lamp housing as the mode of LED heat radiation carrier, in such light fixture, is separated with aluminium base and aluminium lamp housing between LED and radiating fin, and the LED heat is dispersed in the air by the aluminium lamp housing through behind the aluminium base again.The radiating rate of this structure is slow, the LED illumination that only suitable overall power is smaller.

Summary of the invention

Technical problem to be solved in the utility model is exactly at above-mentioned deficiency, and a kind of perfect heat-dissipating be provided, save the energy, safe and reliable a kind of LED lamp system.

The purpose of this utility model can be achieved through the following technical solutions, and the LED lamp system comprises a cover light fixture cooling system.

The LED lamp is characterized in that: polygon tubular guidewire thermic devices one end close installation is in heat sink interior;

The LED lamp is characterized in that: there is heat-conducting liquid polygon tubular guidewire thermic devices inside;

The LED lamp is characterized in that: polygon tubular guidewire thermic devices, an end are radiating fin, and an end has LED lamp pearl;

The LED lamp is characterized in that: LED lamp pearl bottom surface heat transfer piece directly is installed on the polygon heat-transfer device;

The LED lamp is characterized in that: diffuser is installed in the one side of heat abstractor by a pressing plate and securing member;

The LED lamp is characterized in that: lamp holder inside is equipped with power panel;

Compared with prior art, what the utility model adopted is the polygon tubular guidewire thermic devices surface that heat-conducting liquid is arranged in heat sink being in direct contact with in LED lamp pearl bottom, and the design that heat distributes by radiating fin, reduced thermal resistance effectively, the heat of LED lamp can dissipate by heat conduction and heat abstractor fast, and can effectively be strengthened the service life of LED lamp.
