A kind of LED bulb of wide-angle illumination, also comprise shell, base and lamp holder, and described base is connected with lamp holder, in base, be provided with driving power, radiator is arranged on base, and shell is connected on radiator, and described LED light source assembly, column-like projection block and reflector all are positioned at shell.Between shell of the present invention and radiator, form hollow space, column-like projection block is positioned at hollow space, so, area of dissipation is effectively increased, and the dissipation of heat that the LED light source assembly can well be produced is gone out, and extends service life of the present invention.
In order further to strengthen astigmatic performance of the present invention, the surface of described radiator is provided with diffusion layer.
Convenient in order to draw materials, save cost, further, the material of described diffusion layer is titanium dioxide, silica or barium sulfate.
The material of described radiator is metal or pottery.The present invention is when specifically arranging, and radiator preferably adopts metal or the pottery that heat conductivity is high to make.
Further, described case surface is coated with light scattering layer.Light scattering layer is coated in inner surface or the outer surface of shell.
The upper and lower both ends open of described reflector is circular open.So, when specifically arranging, guarantee the bore of its lower ending opening of bore of reflector upper end open.
Further, every stage rank of described column-like projection block sidewall formation all form around one week of column-like projection block the structure of remaining silent.
In order to make structure of the present invention attractive in appearance, the level height of all sites of upper surface, every stage rank is identical.So, step of the present invention is similar to a plurality of frustum platforms or the stacked formation of other polygonal platform, and wherein, each platform is big or small gradual change from the bottom to top, and the face area of the upper surface of below platform is greater than the face area of upper stage lower surface.
Compared with prior art, the present invention has following beneficial effect: be provided with the LED light source assembly inside and outside (1) reflector of the present invention, the inner surface of reflector reflects the light that the LED light source assembly on ledge surface in reflector sends, it is gone out from the reflector upper end open, the outer surface of reflector will be distributed in the light that the LED light source assembly of its exterior circumferential sends and reflect, part light is subject to reflecting the lower area emission to reflector, so, can increase the luminous intensity distribution angle, form the illumination zone of wide-angle.
(2) radiator of the present invention upper surface epirelief forms a column-like projection block, the present invention can strengthen heat dispersion by column-like projection block, the present invention is by arranging step on radiator, and the part from the bottom to top big or small gradual change of column-like projection block between adjacent two stage rank, step is less to the influence of light of reflector reception and reflection, can make the reflector outer surface more receive the luminous of LED light source assembly and reflect, further can increase the luminous intensity distribution angle.
