However, the above-mentioned bulb design may make its light too glaring, and the angle of illumination of the bulb will be limited by the angle of illumination of the lighting module. Therefore, the creator feels that the above-mentioned deficiency can be improved. He is devoted to research and cooperates with the application of theory, and finally proposes a creation that is reasonable in design and effective in improving the above-mentioned deficiency.

The present invention provides a light guiding type light bulb that can control the light output effect through the cooperation between the light guide plate module and the light emitting module.

The embodiment of the present invention provides a light-guide type light bulb, comprising: a lamp body having a lamp cap and a carrying portion, wherein the lamp cap and the carrying portion are respectively located at opposite ends of the lamp body; and a light-emitting module fixed The light-emitting module is electrically coupled to the lamp cap; and a light guide plate module is a hollow column structure, the light guide plate module has an inner plate surface and an outer plate a surface, a light incident surface, and a light guiding microstructure, wherein the inner plate surface and the outer plate surface are opposite inner and outer edges of the hollow cylindrical structure, and the light incident surface is an end of the hollow cylindrical structure Edge, and the light guiding microstructure is formed At least one of the inner panel surface and the outer panel surface; wherein the light guide panel module is disposed adjacent to the light emitting module in an upright manner, and the light emitting direction of the light emitting module is forward to the light incident surface The light emitted by the light emitting module can pass through the light incident surface and enter the light guide plate module, and can pass through the outer surface of the light guide structure.

In summary, the light guide bulb provided by the present embodiment is vertically disposed adjacent to the light emitting module through the light guide plate module, so as to guide the light emitted by the light emitting module by the light guide plate module to make the light Can be distributed in the light guide inner panel module. And the light guide plate module further transmits the light guide microstructure to control the amount of light passing through the light guide plate module, thereby controlling the light output effect of the light guide type light bulb.
