Description

A kind of LED lamp

Technical field

The utility model relates to a kind of light fixture, relates in particular to a kind of LED lamp, belongs to illuminating device.

Background technology

Lamp is the device commonly used of lighting field, the structure of bulb at present commonly used is to be made of lamp holder, Transparent lamp shade and tungsten filament with two power lines, and lampshade is fixedlyed connected with lamp holder, and adds inert gas seal, lamp holder is provided with screw thread, and lamp holder and lamp socket removably connect during use.This bulb source utilization rate is low, and the lampshade that less stable, voltage swells cause breaks bulb is damaged, and energy consumption is higher, and service life is short, has increased use cost virtually.

The utility model content

The purpose of this utility model is: propose that a kind of energy consumption is low, the life-span is long and the high LED lamp of light source utilization rate.

The structure of this LED lamp comprises radiator, LED, pcb board, reflector, power supply changeover device, air vent, lamp holder and lampshade, wherein: the pcb board level is located at the lampshade internal upper part, the horizontal downside of pcb board is installed LED, the horizontal upside of pcb board connects radiator, the place, inner chamber axis of lampshade is provided with reflector, and lampshade is connected with insulator foot, and insulator foot is provided with air vent, power supply changeover device is fixed in the insulator foot, and base surface is provided with screw thread and connects insulator foot.

Described radiator is provided with a plurality of louvres.

The surface of described reflector is a taper surface, and its bottom is connected with insulator foot; Be provided with the LED on wire connecting power converter and the pcb board in the reflector.

In the utility model, the light emission direction of LED is towards lamp holder, wiring and light occlusion issue have been solved, light is fully used by reflector, and is luminous soft, compares with the general lighting lamp and saved energy consumption, the problem of having avoided voltage swells to cause bulb to damage, prolonged service life, stability is high, has reduced use cost.
