Abstract

The utility model relates to a high-power LED lamp bulb which comprises a lamp body, a base and a lamp cap, wherein an LED lamp is installed in the base. A radiating shell taking the shape of a round platform is arranged outside the base, the upper bottom of the round platform is fixedly connected with the base, and the lower bottom of the round platform is fixedly connected with the lamp body. The LED lamp in the base adopts an ACLED (alternating current LED) or a DCLED (direct current LED) as a light source; a groove is arranged on the side face of the round platform, and the cross section pattern of the groove is in a same plane and is formed by a plurality of line segments and curved sections, or the line segments and the curved sections are connected in sequence from beginning to end but do not intersect with each other. The high-power LED lamp bulb increases the radiating area of the lamp and effectively improves the radiating efficiency of the lamp. When the ACLED (alternating current LED) is adopted, the cost of products is saved, and the quality of the products is also improved.

Description

A kind of high-power LED bulb

Technical field

The utility model relates to a kind of light fixture, more particularly, relates to a kind of high-power LED bulb.

Background technology

LED is a kind of semiconductor that electric energy can be converted into visible light, at present, uses the shot-light of LED as light source, have with it advantages such as luminous efficiency height, energy-saving and environmental protection be widely used in people's life various occasions, but also have following not enough:

When 1, LED worked, caloric value was big, the heat radiation difficulty.

2, heat can't shed, and may cause drive circuit or LED itself to burn, and has potential safety hazard.

3, LED can only work under DC (direct current) electricity usually, therefore needs inside or outside current transformer that alternating current is converted to direct current.This current transformer had both increased cost, had reduced the life-span of LED again, and very easily became the weak link in the system, influenced the product quality of light fixture.

The utility model content

The technical problems to be solved in the utility model is that the above-mentioned defective at prior art provides a kind of high-power LED bulb.

The technical scheme that its technical problem that solves the utility model adopts is: design a kind of high-power LED bulb, comprise lamp body, base and lamp holder, the LED lamp is installed in the base.Round table-like heat radiation shell is installed outside base, and the upper base of round platform is fixedlyed connected with base, and going to the bottom of round platform fixedlyed connected with lamp body.LED lamp in the base can adopt ACLED (AC LED) as light source, does not use the supply unit of high pressure to the low pressure conversion, and LED can directly bear AC220V or AC110V.Also can adopt DCLED (direct-current LED), mix power supply changeover device and use the voltage that makes voltage transitions become LED can bear.

As further improvement in the technical proposal, above-described high-power LED bulb, described round table-like heat radiation shell is the alloy shell, side at round platform is provided with groove, the cross section figure of groove is in same plane, is connected in turn and the non-intersect figure of forming with the curved section head and the tail by some line segments, curved section or line segment.The cross section figure that is groove can be bar shaped, raindrop shape, and polygons etc. are multiple irregularly shaped.The material of heat radiation shell can be the heat sink material of aluminium alloy, AL203, ALN or other types.

Above-described high-power LED bulb, described lamp holder can adopt plug-in type lamp holder or spiral lamp holder.To satisfy the connection needs of different occasions.

Above-described high-power LED bulb, the material of described lamp body are glass, transparent resin or other light transmissive materials.

Implement high-power LED bulb of the present utility model, have following beneficial effect:

1, light fixture is provided with the heat radiation shell, adopts aluminium alloy, AL2O3 or ALN, also can adopt other non-conductive but heat conduction material preferably, the heat radiation shell is designed to round table-like structure, and groove is set, and has enlarged area of dissipation, increase the radiating rate of light fixture, improved the efficient of light fixture heat radiation effectively.

2, adopt low-power consumption, high-efficiency LED, reach the effect of power saving, environmental protection, thereby reduce consumer's use cost.

3, the utility model can be made direct insertion and spiral two kinds of specification lamp holders, can satisfy the connection request of different use occasions.

4, the utility model can adopt ACLED (AC LED), need not to adopt inner or outside current transformer, and high pressure is changed to low pressure, and LED promptly directly can bear AC220V or AC110V voltage.Save product cost, improved product quality, enlarged the scope of application of product.Certainly, the utility model also can adopt DCLED (direct-current LED), mixes power supply changeover device and uses, and makes high pressure convert the voltage that LED can bear to, to satisfy different consumers' needs.

5, the utility model simple structure is easy to realize, embodies theories green, energy-conserving and environment-protective.
