Abstract

The utility model discloses an LED bulb, which comprises a lamp holder having a screw thread or bayonet, a lamp and a radiating structure which are mutually connected one by one, wherein a power supply driving circuit is arranged in the lamp; the radiating structure is a preformed unit combining the shapes of cylinder and pyramid; the cylinder is provided with a plurality of radiating channels; a chip packaged LED light source is fixed on the outer surface of each isosceles triangle of the pyramid or pyramid. The LED has wide illuminating scope and big illuminating angle, can replace the traditional common lamp, has excellent radiating effect and generates no gas to pollute the environment. The LED power consumption is one tenth of the power consumption of a common incandescent bulb but the service life is prolonged about 100 times.

Description

A kind of LED bulb
Technical field
The utility model relates to a kind of lighting, especially a kind of LED bulb.
Background technology
The abbreviation of LED luminous secondary body (Light Emitting Diode).Since this semiconductor subassembly development, generally be to use as indicator lamp and display screen, along with science and technology development, LED can use as light source at present.Led light source open name have environmental protection, long service life, energy-conservation, volume is little, in light weight, respond fast, operating voltage is low and the good characteristics of security, therefore is called as the 21 century green illumination light source.Therefore the LED lamp that with LED is light source also continues to bring out.
The LED lamp of prior art, generally all be many of single straw hat types (Lamp) are integrated on the plate or many once encapsulate driving fit or single high power package.And that the bulb lamp of using above-mentioned these light sources exists optical beam ratio is more concentrated, and lighting angle is narrower, does not possess the astigmatic effect of high-quality lamp.Or bright dipping is arranged than even not good, the complex structure of its radiating effect of person, manufacturing cost height.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of simple in structure, radiating effect is good, economic benefit is high, can be used for the high light efficiency of general lighting, the LED bulb of high energy-conservation, high convenience.
The purpose of this utility model is achieved in that a kind of LED bulb, it comprises lamp holder, lamp body and the radiator structure that interconnects threaded or bayonet socket successively, the led light source of the direct packaged type of fixed wafer and lampshade on prefabricated radiator structure, power driving circuit is set in the lamp body, it is characterized in that: described radiator structure is the cylindrical prefabricated component that combines with pyramid or polygonal pyramid shape, on cylindrical, some heat dissipation channels are arranged, the led light source of the direct packaged type of fixed wafer on the outer surface that does not have individual isosceles triangle of pyramid or polygonal pyramid.
The led light source of the fixing direct packaged type of wafer on the outer surface of isosceles triangle, the density of its LED luminous secondary body and power are set according to LED bulb illumination needs.
Described lampshade is transparent glass cover or transparent organic glass cover.
Described drive circuit comprises rectification circuit, holding circuit and filter circuit.
Described radiator structure is the aluminium material radiator structure.
The utlity model has following advantage: the led light source of the direct packaged type of wafer is fixed on the outer surface of each isosceles triangle of the pyramid of radiator structure or polygonal pyramid, make the range of exposures of LED lamp enlarge, light angle is big, therefore can substitute existing general lighting lamp.Radiator structure is the cylindrical prefabricated component that combines with pyramid, on cylindrical some heat dissipation channels are arranged, so it has better heat radiating effect.Adopting the LED luminous secondary body is light source, and it has environmental protection, energy-conservation, advantage such as the life-span is long, and it can not produce the gas that environment is had pollution, and under the same brightness, the power consumption of LED only is 1/10 of ordinary incandescent lamp, and the life-span can prolong nearly 100 times.
Description of drawings
Fig. 1 is the utility model LED bulb perspective view.
The specific embodiment
As shown in Figure 1, a kind of LED bulb, it comprises and interconnects threaded lamp holder 1, lamp body 2 and radiator structure successively, in the lamp body 2 power driving circuit is set, described radiator structure is cylindrical 3 prefabricated components that combine with pyramid 4, some heat dissipation channels are arranged, the led light source 5 of the direct packaged type of fixed wafer on the outer surface of three isosceles triangles of pyramid 4 on cylindrical 3.Described lampshade 6 is transparent glass covers.Described drive circuit comprises rectification circuit, holding circuit and filter circuit.Described radiator structure is the aluminium material radiator structure.
