During enforcement, described cover body inside is respectively equipped with for the ccontaining blind hole of described LED monomer corresponding to the base position of each helical form leaded light post, makes being coated by cover body of LED monomer on every side, to bring into play preferable ray guidance effect.
Keep spacing between described each helical form leaded light post, make each helical form leaded light post can bring into play suitable spiral elasticity effect, so that LED bulb guiding device is not easy impaired when being collided.
Be provided with connecting portion near the position of cover body between described each helical form leaded light post, so that the base portion of each helical form leaded light post is not easy the situation that ruptures.
Described each helical form leaded light post is staggered towards same direction, makes many helical form leaded light post integral body present the taper that opening is expanded gradually, is covered by self or other helical form leaded light post towards the light source of bulb rear irradiation to avoid each helical form leaded light post.
The outer rim of described each helical form leaded light post has arc sections, and wherein the thickness of each helical form leaded light post inboard is greater than its outer edge thickness, can make most light source can concentrate on arc sections thus shines, and the setting that sees through arc sections can make more light sources towards the irradiation of bulb rear, and then makes more wide-angle, more evenly soft of scope that the utility model LED bulb guiding device shone.
Compared to prior art, the utility model LED bulb guiding device can utilize unique helical form leaded light post that lead appropriate location and angle of light source shone, especially specifically the utility model need not be provided with under the situation of speculum, can utilize the leaded light principle that light source is dispersed to the rear of LED bulb suitably, uniformly, and efficiently solve the problem that general LED bulb only can carry out frontlighting.
