Description

A kind of LED lamp
[technical field]
The utility model relates to a kind of lighting device, especially refers to a kind of LED lamp.
[background technology]
In recent years, long service life, the energy consumption of light-emittingdiode (light emitting diode, LED) are low, the saving energy is remarkable, and LED is widely used in daily life as light source.For example at present developed the LED lamp that can be directly installed in common bulb socket, to replace existing bulb lamp.The LED bulb lamp of selling on market substantially all comprises lamp holder, lampshade, aluminium base and is installed on the LED light source on aluminium base.The bottom of aluminium base is provided with heat abstractor, and lamp holder is fixed on the bottom of heat abstractor, and lamp holder and LED light source are electrically connected, and lampshade is mounted on aluminium base, for covering LED light source.
Yet, the characteristic of LED lamp and traditional bulb lamp (such as osram lamp etc.) are very different, because LED lantern festival produces a large amount of heats, so LED light source need to be fixed on to aluminium base or other have on the substrate of thermolysis, then by aluminium base, heat is delivered to heat abstractor, thereby by instant the shedding of the heat of LED light source.LED lamp ability normal operation like this, otherwise be exactly to cause shorten the service life of light-emittingdiode, even burn out.In addition, LED light source needs DC driven, and general electric main is driving LED light source directly, and therefore, LED lamp need to add power supply changeover device AC power is converted to dc source.
Current LED lamp is normally arranged at LED light source and power supply changeover device respectively on different substrates, be made with like this two benefits, the one, cost is lower, because aluminium base etc. have the price of substrate of thermolysis higher, power supply changeover device is arranged to another substrate, escapable cost; The mechanism design of the 2nd, LED lamp is easier to, because the volume of LED bulb lamp is little, is divided into comparatively elasticity of design that two less substrates easily put ,Qie external form mechanism than a large substrate.Yet be divided into the problem of two substrates with regard to considering to connect, general way is to weld two wires to connect LED substrate and drive circuit board, but due to aluminium base good heat dissipation effect, wire will pass heat abstractor and aluminium base, relatively trouble, welds location and waits also inconvenient.On the other hand, in modern science and technology, demand small-sized, frivolous, cost degradation that LED bulb lamp also has, utilizes cable to weld to be electrically connected the structure of LED substrate and drive circuit board, is unfavorable for the Miniaturization Design of LED bulb lamp.
Therefore,, in order to overcome above-mentioned defect, be necessary to provide a kind of improved LED lamp.
