At present, most company's exploitation and the LED bulb lamp light emitting anger of producing are generally accomplished about 180 degree, although can be well-done aspect heat radiation, high power, but the shortcoming that light emitting anger is little, the standard that does not also meet the full Shu Faguang of traditional pyriform bubble lamp, the renewal and perfect that do not continue with product, emerged in large numbers the luminous LED bulb lamp in many batches of full bundles angle on the market, such as the Philip, the history Ford, the companies such as Toshiba, but carefully find, these products normally increase a little reflective parts, perhaps light source are placed on the centre of lampshade, reach the effect of full Shu Faguang, but cost compare is high, and part is many and assembling is complicated, and dispels the heat and badly directly affected the steady quality of product and restricted the lamp power size.

In addition, existing product also has following shortcoming:

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

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

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

Preferably, the heat dissipation channel that described upper fin forms has 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, described lower fin section is arranged on described lampshade inside.

Preferably, it is one-body molded that described radiator adopts die casting aluminium.

Preferably, described radiator inside is provided with fan.

Preferably, described lampshade is for being the high transmission rate lampshade.

Because technique scheme is used, the utility model compared with prior art has following advantages:

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, radiator have ventilation cell every, can take away the heat that is attached to above the fin when making cross-ventilation;

3, about radiator runs through, make ball bubble rear and front end, heat dissipation channel and ventilation cell every heat sinking function is arranged;

Accompanying drawing 2 is the front view of the above part of radiator in the utility model;

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

Wherein: 1, lamp holder; 2, pedestal; 3, radiator; 30, lower fin; 300, ventilation cell every; 31, upper fin; 310, heat dissipation channel; 4, lampshade; 40, ventilating opening; 5, LED lamp plate.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

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

Shown in Fig. 2,3: radiator 3 comprises lower fin 30, is arranged on the upper fin 31 on lower fin 30 tops, lower fin 31 is connected to pedestal 2 tops, upper fin 21 is arranged on lampshade 4 inside, lower 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.
