Description
Technical field
The utility model relates to the LED lighting field, particularly a kind of LED bulb lamp.
Background technology
Existing bulb lamp mostly is conventional tungsten silk bulb lamp, and it is a thermal light source, not only lacks service life, also wastes electric energy, contaminated environment.Existing LED bulb lamp adopts low-power LED as light source more, and it does not have radiator, and in order to reach the needs of brightness, LED is densely distributed, and radiating effect is poor, and the life-span is short.Existing LED bulb lamp also has minority to adopt great power LED, and its heat-delivery surface is smooth, and area of dissipation is little, volume is big, Heavy Weight, and radiating effect is poor, the heat production height of great power LED, its heat can not in time distribute, and causes light decay big, life-span is shorter, adopts constant voltage to drive, and drives unstable, the long-term instability that causes light source of using, and the traditional lampshade of most of use cause luminous intensity distribution inhomogeneous, light efficiency is poor, can not get wide popularization and application.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of radiator volume little, and area of dissipation is big, and good heat dissipation effect drives stable LED bulb lamp.
The purpose of this utility model realizes as follows: a kind of LED bulb lamp comprises installation wiring board, lampshade and the driver of socket, insulating lamp holder, heat radiation cup, single or a plurality of LED; Driver is a constant-flow driver, and it is positioned at insulating lamp holder, and the heat radiation cup removably is fixed on outside the insulating lamp holder, and insulating lamp holder removably is fixed in the socket, and lampshade is installed in heat radiation cup inside groove; There is annular heat radiation wing on the surface of heat radiation cup; The installation wiring board of LED connects constant-flow driver by lead, and constant-flow driver is drawn lead outside socket.
Described lampshade is a glass frosted lampshade, and its inner surface is uneven, and its diffuse reflection multi-angle refraction action makes luminous intensity distribution even, and photochromic evenly soft, the whole structure of bright dipping is better.
Effect of the present utility model is as follows: the design of the annular heat radiation wing of heat radiation cup surface, increased the area of dissipation of heat radiation cup, make the ultra-thin and ultralight of heat radiation cup, reduced the weight of LED bulb lamp, use more conveniently, install more reliably, and reduced the light decay of LED, prolonged its service life, made applying of LED bulb lamp become possibility.And glass frosted lampshade makes its luminous intensity distribution more even, and photochromic evenly soft, the whole structure of bright dipping is better.
