Description

The radiator structure of LED lamp
Technical field
The present invention relates to make light fixture, particularly improve the radiating effect of LED line lamp and the technology in service life with light emitting diode.
Background technology
Now, small-power type LED light fixture has environmentally safe, energy savings, and distinct advantages such as low price just progressively substitute present incandescent lamp and fluorescent lamp, become the dominant force of 21 century adnornment industry illumination.And the LED lamp is to the very sensitive luminescent device of temperature, under the lower situation of operating temperature, could obtain high optical index, the increase of LED lamp unit light flux can make every unit caloric value rise significantly, and the increase of heat makes LED emitting components luminance decay, reduction of service life.Therefore the heat dissipation problem of LED light fixture is an one of problem of promoting the use of the urgent solution of LED lamp illumination.The luminous LED device that the small-power line lamp uses is because the structure of this luminescent device determines the PCB circuit board of this light-emitting device not contact fully with metal shell, influence the heat that the LED light-emitting component distributes and in time comes out the service life of shortening LED lamp.CN101042231A proposes a kind of LED light heat radiation board, and it connects heat pipe to improve radiating effect in the periphery of substrate, because the sealing of heat pipe one end can not form cross-ventilation, and heat pipe extends to the four sides, take big quantity space, not in tune with environment, influence practical effect.
Summary of the invention
The technical problem to be solved in the present invention is to design a kind of radiator structure of LED lamp, reaches raising radiating effect purpose by surface area and the air mass flow that improves radiator.
Technical scheme of the present invention is: the radiator structure of LED lamp, it comprises lamp socket, circuit board and LED emitting components, it is characterized in that establishing axial lumen in the middle of the lamp socket, inner groovy is established on the top of lamp socket, the front and back outer wall of lamp socket is established some tongue and grooves, establish the ventilating opening that communicates with the lamp socket axial lumen in the middle of the end cap at lamp socket two ends, circuit board is located in the inner groovy of lamp socket top, is filling thermal paste between circuit board and the lamp socket He on the circuit board.
The LED light fixture is by lampshade, lamp socket, LED emitting components, circuit board, end cap and lead, and waterproof and dampproof glue layer is formed, wherein, the LED emitting components is pasted and is welded on the circuit board, because circuit board adopts two plane type, circuit board is not contacted fully with lamp socket, toothing is done on the two sides of circuit board, by the moving good heat radiation glue of perfusion, allow circuit board pass to the lamp socket heat radiation by thermal paste, and this lamp socket adopts the good aluminum alloy materials of heat conductivility, and design has many heat radiation tongue and grooves that are parallel to each other on it, increases area of dissipation.The bottom of lamp socket is provided with the radial ventilation mouth that is connected with axial lumen, air can enter in the lamp socket smoothly, two ends from lamp socket spill out again, increase the flowability of air, flow air can be taken away the heat in the lamp socket at any time, reach better heat radiating effect, improve the LED illumination effect, increase the service life.
Because the glue of encapsulation has waterproof and dampproof effect, so this light fixture also has water-proof function, can light work under water for a long time.
