Description

Full-luminous corner LED bulb lamp

Technical field

the present invention relates to lighting technical field, particularly relate to a kind of full-luminous corner LED bulb lamp.

Background technology

LED bulb lamp is the novel energy-conserving light fixture that substitutes conventional incandescent, and it is superior to traditional illuminating product on principle of luminosity, energy-saving and environmental protection aspect.High speed development along with the LED lighting engineering; The energy-saving effect of LED bulb lamp has reached very high degree; Under the situation of equal light efficiency, energy consumption has dropped to 1/2 of incandescent lamp and electronic energy-saving lamp, is trend of the times so the LED illuminating product replaces traditional illuminating product.

are present, and generally accomplish about 180 degree, though can be well-done aspect heat radiation at most company's exploitation and the luminous angle of LED bulb lamp that produces; High power, but the little shortcoming in luminous angle also do not meet the standard that traditional pyriform is steeped the full Shu Faguang of lamp; With the renewal and perfect that do not continue of product, complete emerged in large numbers the luminous LED bulb lamp in many batches of bundles angle on the market, like companies such as Philip, history Ford, Toshiba; But careful discovery, these products normally increase a little reflective parts, perhaps are placed on light source the centre of lampshade; Reach the effect of full Shu Faguang; But cost is than higher, and part is many and assembling is complicated, and dispels the heat and badly directly influenced the steady quality of product and restricted the lamp power size.

In addition, existing product also has following shortcoming:

1), the existing product heat radiation is not enough, the junction temperature of chip height;

2), existing product can not be done high power because heat radiation restricts, big lumen number;

3), existing more than 240 ° luminous angle spare and accessory parts many, produce the assembling difficulty, cost is high.

Summary of the invention

the purpose of this invention is to provide a kind of full-luminous corner LED bulb lamp.

For achieving the above object, the technical scheme that the present invention adopts is:

a kind of full-luminous corner LED bulb lamp; Comprise pedestal, be connected the lamp holder of described pedestal bottom, the radiator that is connected described pedestal top, the lampshade that is connected described radiator top, several LED lamp plates and can drive the luminous driving power of described LED lamp plate; Described radiator comprises following fin, is arranged on the described last fin on fin top down; Described fin down is connected described pedestal top; The described fin of going up is arranged on described lampshade inside, and it is separated that described fin down forms several ventilation cells, and the described fin of going up forms the heat dissipation channel that runs through described lampshade; The bottom of described heat dissipation channel is connected with described ventilation cell is separated, and the top of described heat dissipation channel is connected with the outside through the top of described lampshade; Several described LED lamp plates are arranged on described going up on the fin.

are preferably describedly gone up the heat dissipation channel that fin forms and are had several outer surfaces, and several described LED lamp plates are attached to respectively on several outer surfaces of described heat dissipation channel.

further preferably, the lighting angle of described LED lamp plate is the 100-150 degree.

preferably, it is inner that described down fin section is arranged on described lampshade.

preferably, described radiator adopts die casting aluminium one-body molded.

preferably, described radiator set inside has fan.

preferably, described lampshade is for for the high transmission rate lampshade.

Because the technique scheme utilization, the present invention compared with prior art has advantage:

1, radiator has heat dissipation channel, and air can be formed convection current and take away heat in the heat sink material inside of ball bubble the inside;

2, it is separated that radiator has ventilation cell, can take away when making cross-ventilation attached to the heat above the fin;

3, about radiator runs through, make ball bubble rear and front end, heat dissipation channel and ventilation cell at a distance from heat sinking function is all arranged;

4, lamp plate are arranged on the radiator part that runs through the ball bubble, and the heat of generation imports radiator with shortest path, and guarantee that the light maximum angle of ball bubble shines out.

Description of drawings

Accompanying drawing 1 is a stereogram of the present invention;

Accompanying drawing 2 is the front view of radiator among the present invention with top;

accompanying drawing 3 is the upward view of accompanying drawing 2.

wherein: 1, lamp holder; 2, pedestal; 3, radiator; 30, following fin; 300, ventilation cell is separated; 31, go up fin; 310, heat dissipation channel; 4, lampshade; 40, ventilating opening; 5, LED lamp plate.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

A kind of full-luminous corner LED bulb lamp that are as shown in Figure 1, comprise pedestal 2, be connected the lamp holder 1 of pedestal 2 bottoms, the radiator 3 that is connected pedestal 3 tops, the high transmission rate lampshade 4 that is connected radiator top, several LED lamp plates 5 and can the driving LED lamp plate 5 luminous driving powers.

are like Fig. 2, shown in 3: radiator 3 comprises following fin 30, is arranged on down the last fin 31 on fin 30 tops; Following fin 31 is connected pedestal 2 tops; Last fin 21 is arranged on lampshade 4 inside, and following fin 31 has part also to be arranged on lampshade 4 inside, like this; The locus of driving power just can enlarge, and can accomplish high power.Radiator 3 can adopt die casting aluminium integral type or other Heat Conduction Material moulding.

fin 30 down form several ventilation cells at a distance from 300; Last fin 31 forms the heat dissipation channel 310 that runs through lampshade 4; The bottom of heat dissipation channel 310 and ventilation cell are connected at a distance from 300, and the top of heat dissipation channel 310 is connected with the outside through the ventilating opening 40 at the top of lampshade 4.Like this, 4 top connects radiator 3 from lamp holder 1 to lampshade, and radiator 3 inside have heat dissipation channel 310 to ventilate, and utilize cross-ventilation to take away heat.In addition,, when doing the very big LED bulb lamp of high power, can small-sized fans be installed in that radiator 3 is inner to help heat radiation, can effectively solve the difficult problem of high-power heat radiation because radiator 3 is up/down perforations.

The heat dissipation channel 310 that fin 31 formation are gone up in has several outer surfaces, and like four outer surfaces, several LED lamp plates 5 are attached on four outer surfaces of heat dissipation channel 310.Because the lighting angle of LED lamp plate 5 is the 100-150 degree, for most preferably, therefore can produce the luminous effect in full bundle angle with 120 degree; The heat that LED lamp plate 5 produces reaches on four outer surfaces of heat dissipation channel 310, reaches fin 31 rapidly, because radiator 3 ventilates up and down; Radiator 3 inside and outside can taking away heat through cross-ventilation; Reduce junction temperature, help making high power like this, the bulb lamp of big lumen number.

the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
