Background technology

Energy-saving and emission-reduction are China's important social tasks for a long time, are the key factors of building a harmonious society.Continuous anxiety along with China's energy shortage situation; It is quite important that using electricity wisely has become; With regard to by electric consumption on lighting; If the electric light that national resident uses can have 50% to use the LED illuminating lamp instead, the electric weight that save every year is exactly the summation of power station, Three Gorges generated energy, and therefore constantly popularization and use LED electricity-saving lamp have crucial meaning.At present; Existing its structure of LED lamp of China is basic identical; Be exactly led light source by the LED crystal package one heat sink on; Light-emitting area is by the resin lens packaging protection and carry out lighting angle, and several light sources are installed on the printed wire aluminium base, and aluminium base is installed to again on the radiator lamp housing of an integral body.In order to carry out luminous intensity distribution, on led light source, added lens again, or adopted a plated film reflector with PC or PMMA material, on cover, be split into one by one that the led light source chamber is used for reflecting and light distributing, for water proof and dust proof, add the lastblock glass lamp shade again and carry out sealing.It should be noted that with a plurality of LED concentrate in together when carrying out illumination Design, except that the enough luminous flux of needs and reasonably optical design with guaranteeing that rational light distributes, even more important heat dissipation problem.Be converted into heat more than 80 percent at present approximately in the energy consumption of LED, and semiconductor devices is a non-refractory,, then will influences light efficiency and can cause quick light decay and make the lost of life if can not the heat that produced be led away immediately.Because also there are deficiencies such as radiating effect is not good, light skewness in existing LED illuminating lamp in the design of light fixture; The LED lamp that has caused present mass-producted replace incandescent also only is confined to: mine lamp, various flashlight, emergency light, little wattage reading lamp also belong to low-light level even there is illuminating lamp to be used for normal lighting.Therefore, adopt white LED lamp to replace incandescent lamp fully, also have one section very long road to walk.

Summary of the invention

, light pockety technical deficiency slow in heat radiation to existing LED normal lighting lamp, the utility model provides a kind of full visual angle high brightness pillar LED lamp, to realize the wide-angle lighting effect of high light efficiency.

To achieve these goals; The utility model takes following technical scheme to implement: a kind of full visual angle high brightness pillar LED lamp comprises: lamp holder, plastic fastening, radiator, heating column, led light source plate and lampshade, and said radiator is connected on the lamp holder through plastic fastening; Heating column and radiator are fixedly connected; The led light source plate is bonded in the surface of radiator, and lampshade covers in the outside of heat conduction aluminium post and is bonded in the radiator bottom inside, it is characterized in that:

The said radiator outside is provided with the multilayer fin, and its axial cross section is two-way broach shape;

The radial section of said heating column is circular, and the excircle of annulus is provided with many radial teeth;

Said led light source plate is many, and wherein a part is bonded in the bottom of heating column, and a part is with on the cylindrical outer surface that evenly is bonded in heating column;

On the said led light source plate one or several light emitting sources can be set.

Many that are provided with on the excircle of the utility model through broach shape fin on the radiator and heating column are radial tooth, will immediately conduct from the heat that the led light source plate gives out, and guaranteed light efficiency, delayed light decay, have prolonged service life.

The utility model adopts a plurality of led light sources with the outside evenly issue light of the form of various visual angles, realized the illumination purpose of various visual angles, comprehensive, high brightness.

The utlity model has the advantage that novel in design, rational in infrastructure, brightness and light efficiency are high, light decay is slow, the life-span is long.

The specific embodiment

With cylindrical built-in heating column surface five equal portions (five ledlight source plates 6 being set at the heating column outer surface) is example.Shown in accompanyingdrawing 1,radiator 3 is connected on thelamp holder 1 throughplastic fastening 2, andheating column 4 is fixedly connected withradiator 3; Five ledlight source plates 6 are bonded in the surface of the bottom external cylindrical surface ofheating column 4 with the form of circumference in equal parts, and every led light source plate is provided with three led light sources; Other has three ledlight source plates 6 to be bonded on the bottom face ofheating column 4, and every led light source plate is provided with a led light source; Lampshade 5 covers in the outside ofheating column 4 and is bonded inradiator 3 bottom inside.

The utility model is the broach shape that is parallel to each other with the multilayer fin in the radiator and is spaced, and purpose is in order to increase the area of dissipation of radiator; Many radial teeth are set on the excircle of heating column; Be for the heat that will give out from the led light source plate to greatest extent from the surface conductive of heat conduction aluminium post to radiator; So that radiator can immediately distribute heat energy; Guarantee that semiconductor devices is not damaged, farthest guaranteed light efficiency, delayed light decay, thereby reached the purpose that increases the service life.

The utility model is arranged on a plurality of led light sources on the light source board; And adopt many light source boards with various visual angles form be uniformly distributed in heat conduction aluminium post around; The light that led light source is sent evenly distributes away on wide-angle ground, thereby realizes various visual angles, comprehensive, highlight illumination purpose.
