At present, LED (light emitting diode) technical development is rapid, and the ratio that led light source occupies on illumination market is increasing.The appearance of the great power LED product of 80lm/W makes the trend of LED replacement tungsten filament lamp for general service more and more obvious.
Than traditional light source, great power LED is as lighting bulb, and its advantage is low-voltage power supply, and single-chip LED operating voltage is generally at 3～4 volts, and is far below the operating voltage of common bulb light source, safe and reliable; Simple in structure, belong to solid light source, to compared with tungsten light source, have shock-resistantly, vibration resistance is difficult for advantages such as fragmentation; LED is a cold light source, and controllability is good, and the response time is fast, frequently light on and off repeatedly, and traditional tungsten light source is if frequent light on and off must make the life-span die-off owing to expanding with heat and contract with cold fast; The long service life of led light source reached more than 50,000 hours, was 4 to 5 times of conventional light source such as incandescent lamp, avoided frequent maintenance and replacing; LED is energy-efficient, and its luminescent spectrum nearly all concentrates on visible light frequency band, and illuminating effect is more energy-conservation more than 50% than conventional light source; The led light source environmental protection, no harmful element and heavy metal, pollution-free in the production process.
At present, the light source that mainly uses of LED bulb is the stand type LED light source on the market.The stand type LED luminous intensity generally has only 2～3lm at present, so this type of light source adopts many stand type LED to form usually, the light fixture cost is low, and is simple in structure.But because number of light sources is many, the uniformity of led color, brightness is difficult to guarantee, and the stand type LED decay is very fast, needs to change about by 2 years, and practicality is not strong.The luminous flux of single great power LED can significantly reduce the light source usage quantity of LED light fixture more than 80lm at present, makes uniformity relatively easy to control, the reliability height.But caloric value is bigger during great power LED work, if can not distribute heat, will cause the life-span of LED bulb to descend, so heat dissipation problem is the problem that must solve in the great power LED use.
The utility model content
The purpose of this utility model just is in order to solve the deficiencies in the prior art, provides a kind of heat radiation good, high-power LED bulb simple in structure.
The utility model adopts following technical scheme:
A kind of high-power LED bulb, comprise lampshade, lamp holder, lamp socket and be arranged on lampshade interior light emitting source and the connector that is connected lamp holder and lamp socket, it is characterized in that, described light emitting source is the great power LED that is built in lamp socket and the lampshade, LED is arranged on the circuit board, and circuit board is connected with drive circuit module.
As further specifying of such scheme, described lampshade is a globe holder.
Described connector one end is fixed by screw thread and gluing mode and lamp holder; Mode and a lamp socket by gluing is fixed.Connector material mainly is resistant to elevated temperatures ebonite.The effect of connector mainly is to connect lamp socket and lamp holder.By changing the radius of connector, can make lamp socket cooperate different lamp holders to use.Simultaneously, connector also provides more assembly space for drive circuit module, reduces technology difficulty.
Great power LED is welded on the circuit board, and circuit board is connected with lamp socket by the mode of screw and heat-conducting silicone grease.
Circuit board adopts the good aluminum plate material of heat-conducting effect, and is furnished with the set screw hole.
There is the ring-shaped step structure in order to the support circuit board lamp socket inside, and is furnished with the screw hole with the corresponding fixing circuit board of circuit board.
Lamp socket is an aluminum material, and appearance adopts straight striated structure down.
Above-mentioned high-power LED bulb is characterized in that lamp holder and lamp socket are to be connected by connector.
Above-mentioned high-power LED bulb is characterized in that connector one end fixes by the mode and the lamp holder of screw thread and gluing; Mode and a lamp socket by gluing is fixed.
Above-mentioned high-power LED bulb is characterized in that circuit board is connected with lamp socket with heat-conducting silicone grease by screw.
Above-mentioned high-power LED bulb is characterized in that circuit board is the aluminum plate of good heat conduction effect, and is furnished with the set screw hole.Screw hole is corresponding with the position, hole of lamp socket, generally uses 3 screw holes to position fixing.
Adopt the utility model of said structure to have advantage to be:
1, good heat dissipation effect, circuit board are close to aluminium matter lamp socket, and the heat that produces when making great power LED work can pass to lamp socket apace, utilizes the bigger surface area of lamp socket to dispel the heat, and guarantee light fixture ground reliability.Aluminum material has the capacity of heat transmission preferably, and the straight striated structure down of appearance has increased the area of dissipation of lamp socket greatly.The heat that produces when whole holder structure can be worked great power LED is dispersed in the extraneous air well, prolongs lamp life, guarantees that light source is normally luminous.
2, simple in structure, simple installation, the part that the utility model adopts is installed simple.
3, the utility model uses the material of atomizing printing opacity, and it is even to use light effect, and simultaneously because the bulb inner light source is many great power LEDs, and light-emitting area is little, the lampshade dazzling sense of spot light that the outside is watched that can atomize beautifies the light fixture outward appearance.
