Description

LED light lamp

Technical field

The utility model relates to a kind of light fixture, especially a kind of LED light lamp.

Background technology

Light emitting diode is as a kind of illuminating source, and it is low to have energy consumption, and the plurality of advantages such as caloric value is lower, long service life have been applied in illumination and the decorative lamp more and more widely.

The early stage LED light lamp that occurs generally is that light emitting diode is installed in the plastics Lamp cup, this product is poor owing to radiating effect, the brightness of LED is little and the low inferior reason of light efficiency, so that the service life of LED light lamp is short, be difficult to satisfy normal illumination needs.For solving the problem of brightness, the a plurality of light emitting diodes of serial or parallel connection increased brightness during the lamp of being everlasting was cherished, although this technology has solved the problem of illuminance deficiency, must bring larger caloric value owing to increase light source, dispelled the heat into a great problem of this technical field.

Normal LED light lamp mainly comprises light emitting diode, metal shell and power supply circuits at present, around shell, be provided with the fin of bottom-up extension, thereby increased area of dissipation, also lens have been installed additional at light emitting diode, light efficiency is improved, but so that whole fitting structure is complicated, good night, and radiating effect is still not good.

The utility model content

In view of above-mentioned condition, be necessary to provide a kind of led lamp simple, good heat dissipation effect that connects up.

For solving the problems of the technologies described above, a kind of LED light lamp is provided, comprise the housing that lampshade and tail-hood combine, in this housing, be disposed with drive plate, heat abstractor and pcb board, be welded with some light emitting diodes on this pcb board, this drive plate is electrically connected this pcb board and drives this pcb board is the light emitting diode power supply, and this heat abstractor is cylindric, and this pcb board is wrapped in outside this heat abstractor.

This pcb board is by bonding this heat abstractor of heat-conducting glue.

This drive plate one end is provided with the first pin, and this first pin passes this tail-hood external power supply.

The other end corresponding with the first pin on this drive plate is welded with the second pin, and this second pin and this pcb board are electrically connected.

This pcb board is the flexible PCB plate, this flexible PCB plate is folded into the shape corresponding with the heat abstractor profile, this flexible PCB plate comprises rectangular portion and rounded portions, and this rectangular portion is wrapped on the cylindrical wall of this heat abstractor, and this rounded portions covers on this heat abstractor roof.

This lampshade inner wall edge is provided with internal thread, and the outer mural margin of this tail-hood is provided with external screw thread, and this lampshade and this tail-hood are threaded connection and combine a housing.

Above-mentioned LED light lamp passes through a plurality of LED weldings on the flexible PCB plate, this flexible PCB plate can be folded into the shape corresponding with heat abstractor, so that simple, easy to assembly, the low cost of manufacture of whole LED light lamp wiring, and good heat dissipation effect.
