Summary of the invention
The technical problems to be solved in the utility model is to design a kind of heat radiation and waterproof construction of LED lamp, reaches raising radiating effect purpose by surface area and the air mass flow that improves radiator.
The technical solution of the utility model is: the heat radiation of LED lamp and waterproof construction, 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 establishing heat radiation and watertight composition between circuit board and the lamp socket and 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.
