Description

LED lamp

[technical field]

The present invention relates to a kind of LED lamp, particularly a kind of have an excellent heat dispersion performance, easy for installation, and LED lamp easy to maintenance.

[background technology]

In traditional lighting engineering, use osram lamp more, due to power consumption and volume large, luminous efficiency is low, the life-span is short, and more and more can not adapt to the needs of modern society.Along with the development of semiconductor technology, power consumption and volume are little, and luminous efficiency is high, and the application of the LED of life-span length in electric light source technology is more and more subject to people's attention.

Progress along with technology, light emitting diode (LIGHT EMITING DIODE, abbreviation LED) application is increasingly extensive, especially the power of LED is updated raising, LED shows the field infiltration and development to lighting source by signal gradually, as road lighting, tunnel illumination, the large-power lamp fields such as factories and miness illumination.With conventional light source mutually this, LED also has advantages of a lot of uniquenesses, this is as little in luminous point, be easy to carry out optical design, and Luminaire efficiency can do very highly, therefore compares with conventional light source and has huge energy-saving potential.In addition, the LED life-span is long, and shock resistance is good, and these features all make LED in road lighting, and tunnel illumination has better advantage in the great power LED application such as factories and miness illumination.

Yet the popularization of high-power LED lamp, facing maximum problem is that luminous total brightness is low.For improving luminous total brightness, generally take to improve single LEDs brightness, or by many packaged LED lamp pearls, the way of taking connection in series-parallel to gather together.No matter improve the brightness of single chips, or the method that gathers together of connection in series-parallel, all will add high-powerly, all can sharply strengthen hot generation.The general single power of LED lamp pearl is all that this is less, brightness is inadequate, and in order to improve brightness, people often use a plurality of LED lamp pearl combinations as a light source, be fixed on a circuit board and radiator simultaneously, LED light source be sealed in the cavity of a sealing simultaneously.Fin by its back during the work of LED light fixture dispels the heat, thereby this gathers and cause reducing LED effect and the problem that reduces LED lamp life with heat with regard to having caused heat to be difficult for outer faling apart.In order to improve radiating efficiency, also have design that fin is directly exposed in air, this conveniently sharp airborne greasy dirt and dust be easy to gather on fin, affected the radiating efficiency of street lamp, thereby affected service behaviour and the life-span of LED.The simultaneously requirement due to degree of protection adopts the modes such as fluid sealant that the element sealings such as LED are formed to an integral body that is difficult to dismounting, i.e. integral LED street lamp, and on-site maintenance will be very difficult like this, increases manually consuming time.
