Description of drawings
Accompanying drawing 1 is stereogram of the present utility model;
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.
