When the LED unit generates a light source, the part of the light material can be irradiated to the appropriate position and angle through the residual light guide (4) to change the illumination angle and range exhibited by the original LED unit. The light source can be illuminated in a wider angle, more uniform and soft manner through the guidance of the LED light guide of the present invention. In implementation, the inside of the cover body is respectively provided with a blind hole for accommodating the LED unit corresponding to the base position of each spiral light guide column, so that the periphery of the LED unit can be covered by the cover body to play Good light guiding effect. A distance is maintained between the spiral light guiding columns, so that each of the spiral light guiding columns can exert an appropriate spiral elastic effect, so that the LED light guiding device is not easily damaged when it is subjected to a collision. A connecting portion is provided between the spiral light guiding columns at a position close to the cover body, so that the base portion of each of the spiral light guiding columns is less likely to be broken. The spiral guide surfaces are staggered in the same direction, so that the plurality of spiral guide wires are generally tapered to be gradually expanded by π, so as to listen to each of the spiral guides toward the lamp, or other snails. The remaining light guides are covered. 4 M396928., the outer edge of each of the spiral light guiding columns has a circular arc portion, and wherein each of the spiral f-light columns has a thickness greater than a thickness of the outer edge thereof, so that most of the light sources can be in the arc of the city. The part is irradiated, and the arrangement of the arc portion allows more of the light source to be directed toward the bulb, and the range of the LED is more wide-angle, more uniform and softer. Compared with the prior art, the LED light bulb light guide device can use the unique guide button to illuminate the light material to the proper position and the limb, especially the special 疋 创作 creation without the need of a mirror. The light guiding principle can be utilized. • The light source is properly and evenly dispersed to the rear of the led bulb, which effectively solves the problem that the general LED bulb can only be used for front lighting. According to the technical means of the present invention, the following is suitable for the implementation of the present invention and is accompanied by a schematic description as follows: , "工"月^阅第@@,图图The preferred embodiment of the present invention is disposed on the appearance of the LED bulb end w and a cross-sectional view. In the illustration, the guide wire 10 is a light-emitting impurity disposed in the -LED bulb 20, and the LED bulb 2〇, at least the package = a base 21 - a light-emitting module disposed at the front end of the lamp cap 21, the group 22, the light-emitting module 2] has a fine-grained coffee cell 23 light = light illumination. The x-ray device is made of a light-transmitting material, and has a mounting device. The outer surface of the cover U is provided with a plurality of helical guide columns corresponding to the position of the nozzle. U3, and Each of the spiral-shaped light beams 12 is circulated and extended in a direction away from the center point. ’, the third _ three shows the best _ _ light guide column diagram of this creation. In the figure, the inside of the cover 11 corresponding to the spiral light guide i2 is provided with a plurality of positions respectively for the periphery of the LED unit 23 to be covered by the cover holes 13, 12 It has a circular arc portion 14. When the LED unit a generates a light source, the spiral light guide can be guided by the screw guide, and a part of the light source can be guided to the appropriate column 12 to diffuse the light from the arc portion 14, and the light is emitted. In particular, the visible light source illumination direction. Under the original LED unit 23, please refer to the fourth figure and the thickness hl of the inner side of the solid and _12 is greater than the outer _, _, the light column most of the light source can be concentrated in the arc portion 14 to make a mistake to the two = The number of spiral-shaped light guide columns 12 is considered to be two === 'take Figure 5 as an example'. The spiral guide point located above, for the downward rotation of the spiral light guide column 12 to the center point = can avoid each spiral The light guide column U hunts this or other spiral light guides 12 to avoid the π light source being reflected by itself toward the bulb. ~ The money arc 14 guides the light source to maintain a proper spacing toward the distance S. The result is pm, and the guide can play the appropriate spiral elasticity. The H can produce a moderate elastic concession without collision. The position near the cover U is set such that the base of the beam-shaped beam 12 is less prone to breakage of 6 M396928. In summary, the LED light bulb light guide device 10 can use the unique spiral light guide column I2 to guide the light source to the appropriate position and the degree of light, and use the light guiding principle to properly and evenly distribute the light source to the (four) lamp to The effective riding angle of the LED (four) is comprehensive.
