A kind of LED annular light source

Technical field

The utility model relates to a kind of led light source, more particularly, is a kind of LED annular light source that is applicable to multiple light fixture.

Background technology

The LED light fixture with its technical characterstic such as efficient, energy-conservation, long-lived, small and exquisite, is becoming main force's product of illumination market of new generation, and is effectively spurring the high speed development of environmental protection and energy-conservation industry.China's illumination market is large-scale, and product is based on conventional lamp such as incandescent lamp, fluorescent lamps.According to the light fixture sales volume, the LED lighting is less than 1% in the share in general illumination market, becomes the lighting product of main flow far away.Trace it to its cause and be;

1. the price of present indoor LED lighting is up to 40 times also far above conventional lamp, minimumly also reaches 3 times.

2. based on the analysis of Life Cycle Cost of indoor LED light fixture, the LED lighting is compared with the conventional lamp of equal usefulness, and overall life cycle cost and the traditional lighting of indoor LED lighting remain basically stable.

The utility model content

The purpose of this utility model is to provide that a kind of light source and power supply are integrated in one, low cost of manufacture, LED annular light source that interchangeability is strong.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of LED annular light source comprises annular base plate, light source, power supply, it is characterized in that: light source and power supply are located on the annular base plate, and the centre of annular base plate is provided with cable hole.

Further, described power supply is surrounded by light source.

Further, respectively be provided with a screw hole on the annular base plate of cable hole both sides.

The utlity model has following beneficial effect:

(1) power supply of this LED annular light source and light source are arranged on the same annular base plate, have realized the integrated of power supply and light source, can directly give the electric main of AC connector input 220v;

(2) it is simple in structure, and interchangeability is stronger, is common to LED bulb lamp, LED shot-light, LED bulkhead lamp capable, LED street lamp, LED Down lamp, LED desk lamp etc., and cost of labor, the cost of material is low, and suitable automation is produced in a large number.

The specific embodiment

As shown in Figure 1, 2, a kind of LED annular light source comprises annular base plate 1, light source 2, power supply 3, it is characterized in that: light source 2 and power supply 3 are located on the annular base plate 1, and annular base plate 1 can be made by aluminium.The centre of annular base plate 1 is provided with cable hole 4, the AC connector is arranged on cable hole 4 here, be that with the difference of traditional LED light fixture maximum traditional LED lamp power 3 and light source 2 independently separate, the electric main of 220v need transfer safe DC voltage to by power supply 3 could be used to light fixture, and the power supply 3 of this LED annular light source and light source 2 are arranged on the same annular base plate 1, realize the integrated of power supply 3 and light source 2, can directly give the electric main of AC connector input 220v.

Further, power supply 3 is surrounded by light source 2, and as Fig. 1, shown in Figure 3, light source 2 can be the integrated encapsulation of many led chips, as Fig. 2, shown in Figure 4, also can be that many led light sources paster mode is attached on the annular base plate 1.

Further, respectively be provided with a screw hole 5 on the annular base plate 1 of cable hole 4 both sides, conveniently stamp screw annular base plate 1 is fixedlyed connected with the connector of back.

A kind ofly preferred embodiment be:

When using, give the electric main of AC connector input 220v with a kind of joint that is complementary with the AC connector, alternating current arrives power supplys 2 devices by cable hole 4, and power supply 2 transfers the electric main of 220v to safe direct current and supplies with light source 2 uses.

This LED annular light source is common to LED bulb lamp, LED shot-light, LED bulkhead lamp capable, LED street lamp, LED Down lamp, LED desk lamp etc., its simple in structure, ease of assembly; Cost of labor, the cost of material is low, is conducive to automation and produces in a large number.

By LED being driven the research that chip and light source are integrated designing technique, make light (lens, lamp), machine (lamp socket, radiator), electricity (electrical power connection block) interface of LED lighting source module group unified, and it is low to reach cost, interchangeability is strong, the standardization purpose.Realize that LED illuminating product overall life cycle cost is lower than more than 50% of traditional lighting.Effectively overcome integral LED illuminating product cost height, interchangeability is poor, use is inconvenient, difficult in maintenance, the weakness that will be difficult to upgrade future.Be conducive to each manufacturer production division of labor of industrial chain and cooperate, be convenient to the consumer and select, use product, finally realize the purpose of industrialization.

Above-described only is preferred embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, these also should be considered as belonging to protection domain of the present utility model.
