Description

Split type LED lamp
Technical field
The utility model relates to a kind of LED lamp, particularly, relates to a kind of split type LED lamp, and it belongs to the LED technical field of semiconductor illumination.
Background technology
The LED lamp mainly comprises LED bulb and LED shot-light.Along with the lifting of LED performance and the decline of cost, obtained fast development with LED as the illuminating product of light source, and replaced the traditional lighting product gradually and be applied to some indoor and outdoors illumination places.In the traditional lighting product, incandescent lamp and halogen tungsten spot lamp are representative class general illumination light sources.Because the light efficiency of incandescent lamp and halogen tungsten spot lamp is very low, have only about 15lm/W, therefore, adopt LED lamp replacement incandescent lamp and halogen tungsten spot lamp to have the considerable energy saving advantage.
But the problem that LED lamp self exists is, the light fixture light efficiency is subjected to the influence of junction temperature of chip bigger, and higher junction temperature of chip will cause light efficiency to occur obviously descending, and can have influence on the service life of LED lamp.Therefore, the heat dissipation problem of solution LED lamp is most important for the performance that promotes the LED lamp.Because conventional lights is exactly to rely on the hyperthermia radiation effect realization of filament self luminous, does not therefore have the needs of heat radiation.This causes can being subjected to the restriction of conventional lamp size when replacing conventional lights with LED, can be less for the heat-dissipating space that utilizes in the LED lamp thereby cause.
Therefore, how making full use of the structure space of conventional lights, make the LED lamp can satisfy the standard-required of illumination, can provide enough heat-dissipating spaces again, is a difficult problem of present LED modulated structure design.
Another aspect, the structural design of LED lamp generally adopts monolithic construction at present, and the radiator of lamp both had been used for fixing led light source, and the chamber in the radiator also is used to place the led driver spare of driving LED light source simultaneously.Adopt this structure, on the surface, integrated heatsink has increased the area of dissipation of LED lamp.But, in fact,, will cause the temperature of the driving element in the radiator obviously to rise because the heat that is produced in the led light source can conduct to entire radiator.Well-knownly be, led driver spare is for the sensitiveness of temperature even can surpass led light source, and the principal element that influences the LED lamp life-span no longer has been a led light source, but driving element.So monolithic construction can make the life-span of driving element obviously shorten, and then cause the lost of life of LED lamp, this of having become the LED field relatively is difficult to the technical barrier that solves.
In view of the above-mentioned defective of prior art, need a kind of new LED lamp.
The utility model content
The purpose of this utility model provides a kind of novel split type LED lamp, to overcome the above-mentioned defective of prior art, this split type LED lamp can prolong the life-span of LED lamp significantly, carries out the heat radiation of LED lamp effectively, thereby makes the service life of LED lamp and the requirement that performance satisfies illumination.
Above-mentioned purpose is achieved through the following technical solutions: split type LED lamp, comprise radiator, led light source, led driver spare and lamp holder, wherein, this split type LED lamp is provided with the electrical equipment box separate with described radiator, this electrical equipment box and described radiator are provided with at interval, described led light source is fixed on the described radiator, and described led driver spare is arranged in the described electrical equipment box, and described lamp holder is fixed on the described electrical equipment box.
Preferably, the interval between described electrical equipment box and the described radiator forms first vent passages.
Preferably, described radiator comprises a plurality of radiators, and has between the adjacent described radiator at interval, and this forms second vent passages at interval.
Preferably, described radiator comprises the radiator with a plurality of radiating surfaces or a plurality of radiating fins.
Preferably, also be equipped with on the described radiator and the supporting lampshade of described led light source.
By technique scheme of the present utility model, described split type LED lamp has been broken through the monolithic construction method for designing of traditional LED lamp, the LED lamp is designed to split-type structural, make the electrical equipment box of radiator and placement led driver spare spaced apart, thereby avoided led driver spare to be subjected to the led light source heat effects and cause temperature too high, prolonged the service life of LED lamp.Be equipped with vent passages between the radiator inside of split type LED lamp of the present utility model and radiator and the electrical equipment box, its radiating efficiency height, long service life is a kind of important breakthrough and the innovation to present LED modulated structure.That is to say, the utility model is by being designed to split-type structural with the LED lamp, the electrical equipment box of radiator and placement driving element is separated, avoided driving element to be subjected to the led light source heat effects, and on the basis of split-type structural, the structure of the radiator by improving the LED lamp is strengthened the heat radiation of LED lamp, preferably resolve the problem that the LED lamp body is long-pending little, heat-dissipating space is not enough, improved the performance of LED lamp.
