Abstract
The utility model relates to the technical field of lighting, in particular to a high-power light-emitting diode (LED) lamp. The high-power LED lamp comprises a lamp body, a lamp cap and an LED component. The lamp body comprises a radiator body and a shell body, wherein the radiator body is a cylinder. One end of the cylinder is sealed, and a circle of heat dissipating fins are evenly arranged on the outer wall of the cylinder. The LED component is installed at the sealed end of the radiator body, and the inner wall of the shell body is connected with the heat dissipating fins to form an annular cross-ventilation channel. When the high-power LED lamp is in use, heat generated by the LED component is transmitted to the position between the radiator body and the shell body from an installing end plate through the heat dissipating fins, cold air flows circularly inside the lamp body through the cross-ventilation channel, heat is led out of the lamp body so that the purpose of circular heat dissipation can be achieved. The high-power LED lamp integrated heat conduction and heat dissipation, the middle step of heat conduction is reduced, heat dissipating efficiency is improved, and the service life of the LED lamp is prolonged. In addition, the high-power LED lamp is simple in structure, convenient to install, and good in stability.

Background technology
The LED light fixture is with the light fixture of light-emitting diode chip for backlight unit as luminous original paper.Led chip is in when work, is subjected to environment temperature and light emission rate and is inversely proportional to and concerns that temperature is more high, and light emission rate is more low, and when temperature reached the led chip maximum temperature, LED can't operate as normal, even burns.So we need by large tracts of land in using, and the heat that well behaved radiator comes to produce when luminous LED is emitted in the air.
Existing LED heat dissipation technology generally adopts the form of simple radiating sheet.The LED lamp is fixed on the fin, distributes by the heat of fin with its generation.But the method for this dependence fin natural radiation heat radiation makes lamp interior assemble a large amount of hot-airs, radiating efficiency is low, whole light fixture all is in the thermal source radiation, LED is for a long time in hot environment work, especially more undesirable at the radiating effect of tools such as great power LED, be difficult to play substantial effect.For addressing the above problem number of patent application be: 201110330466.4 disclose a kind of high-powered LED lamp, comprise at least one light emitting diode, substrate, lamp casing and the installation lamp holder of light emitting diode be used for to be installed, it is characterized in that: described substrate lower end is provided with heat abstractor, described heat abstractor comprises fin, described fin is fixedlyed connected with substrate by first support, and described heat abstractor also comprises at least one radiator fan.This kind high-powered LED lamp is strengthened the air draft effect of radiator by set up fan at lamp body, though can overcome the problems referred to above to a certain extent, power consumption is big, the production cost height, lamp body structure complexity, volume are big.
The utility model content
For overcoming the deficiency in the above-mentioned technology, the utility model provides a kind of high-power LED lamp, comprise lamp body, be used for the lamp holder of fixed lamp body and be installed on the interior LED assembly of lamp body, it is characterized in that: described lamp body comprises radiator body and housing, described heat radiation main body is the cylindrical shell of end sealing, the outer wall of cylindrical shell is provided with a circle radiating fin uniformly, and described LED assembly is installed on the blind end of heat radiation main body, and the inwall of housing and radiating fin are connected to form a circle air convection channel.
Further, the LED assembly comprises COB module, led chip compressing tablet, lens.
Further, lamp body comprises the last lamp body that is provided with blind end and the following lamp body that is connected with last lamp body by screw thread, and described COB module and led chip compressing tablet are installed on the blind end of lamp body, and lens are fixedly installed in down on the lamp body.
Further, radiator and housing are that aluminum material is made.
Further, radiator and housing are one-body molded.
Further, radiator and housing are columnar structured.
By above-mentioned to description of the present utility model as can be known, when this kind high-power LED lamp uses, the heat that the LED assembly produces is transmitted between heat radiation main body and the housing by radiating fin by end plate is installed, colder air circulates in lamp body by convection channel, heat is derived outside the lamp body to reach the purpose of circulation heat radiation, its heat conduction, heat-radiating integrated, reduce heat conducting intermediate link, improve radiating efficiency, prolong the service life of LED lamp, this kind high-power LED lamp is simple in structure, easy for installation in addition, good stability.
