In order to eliminate this uncomfortable sensation, some designers in the LED industry are also inquiring into technology and the method that LED bulb lamp lighting angle is increased, for example, Zhou Zhibang discloses a kind of LED ball bulb in the patent No. is " a kind of wide-angle ball bulb " of ZL201120374658.0, its lighting angle can reach 270 ~ 300 degree, but there are two significantly deficiencies in it: the one, and the length of luminous foam part only accounts for 1/2 of ball foam (removing the screw socket part), radiator accounts for 1/2, in appearance with the few of difference of LED bulb lamp of main flow; The 2nd, there is the inhomogeneous defective of bright dipping in the optical design, through optical analog, according to the rules 1/2nd light intensity angles definition, actual lighting angle only has about 150 degree, and is too wide in the gap with described 330 degree lighting angles.

Summary of the invention

For the problems referred to above, the utility model purpose is to provide a kind of Effective Raise lighting angle, and the good LED ball bulb of thermal diffusivity.

For achieving the above object, the technical scheme that the utility model proposes is: a kind of LED ball bulb, comprise glass foam, radiator lamp body, led light source, and radiator lamp body is provided with screw socket; It is characterized in that: be provided with a power supply placed cavity in the described radiator lamp body, described radiator lamp body is provided with a heat conducting element, and described led light source is installed on the heat conducting element; Described glass foam accounts for the volume of LED bulb lamp more than 2/3.

Further, described led light source is LED COB light source.

Further, described glass foam inboard is coated with the fluorescence diffusant.

Further, described radiator lamp body is the ceramic heat sink lamp body.

Further, described heat conducting element is the heat conduction aluminum component.

Further, also be provided with heat-conducting silica gel sheet between described heat conducting element and radiator lamp body.

Adopt technique scheme, the beneficial effect that LED ball bulb of the present invention has is:

1) have the lighting angle of super large: lighting angle can reach more than 330 degree, is twice above than the lighting angle of general LED bulb lamp;

2) light-emitting zone is interior luminous even: because the agent of the inboard spraying of larger foam diameter and foam diffusion fluorescence makes the light-emitting zone of bulb lamp interior luminous even, free from glare;

3) the little efficient of ceramic heat-dissipating volume is high: owing to having adopted the ceramic heat-dissipating body of high infrared radiation heat-sinking capability, compare with the aluminium radiator, area of dissipation reduces 2/3, make radiator of the present invention part identical with the compact fluorescent lamp (being commonly called as electricity-saving lamp) of traditional equal-wattage, sense organ is comfortable;

4) compare the sense organ with similar profile with traditional frosted incadescent lamp bubble: identical with the outward appearance of traditional frosted type incandescent lamp bulb because the foam size occupies 2/3 of whole lamp body, and foam part uniformly light-emitting, visual sense feeling is comfortable.
