[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] See Figures 1 to 4 As shown, a novel linear light guide bulb comprises a lamp holder 1, a lamp base 2 connected to the lamp holder and a light source board 3 fixed to the lamp base, a lamp housing 4 is fixed to the lamp base, and a driving power source connected to the light source board is arranged in the lamp holder. In this embodiment, the above structures are conventional structures of the prior art and are simply applied, and the lamp housing is a spherical lamp housing, a cylindrical lamp housing, a truncated cone lamp housing or a rhombus lamp housing.

[0023] In actual application, a columnar light guide 5 is provided in the lamp housing, and a plurality of strip light guides 6 are embedded in the columnar light guide, and the strip light guides are on the same circular ring; the diameter of the strip light guide is 1-2.5 cm, and the strip light guide is a light-transmitting plastic structure; the columnar light guide is a glass light guide. The light can pass through the strip light guide to the columnar light guide, and at the same time, in actual application, the strip light guide is a colored structure. Specifically, the strip light guide is one or more combinations of red, yellow, green, blue, purple, and cyan. When not illuminated, the strip light guide inside can be seen, thereby improving the decorative effect, and when illuminated, the strip light guide can also be illuminated to produce line light, which is beneficial to improving the light guiding and decorative lighting effects, and is highly practical.

[0024] During assembly, the end face of the columnar light guide is attached to the light-emitting surface of the light source board and the lamp beads of the light source board are located at the center of the ring where the strip light guide is located; the light of the light source board passes through the strip light guide, the columnar light guide and then irradiates outward through the lamp housing. With the above structure, the light of the lamp beads on the light source board can completely enter the columnar light guide. In actual application, the columnar light guide can be a cylindrical light guide or a rhombus-shaped light guide.

[0025] In actual application, the diameter of the columnar light guide is the same as that of the light source board, and is smaller than the diameter of the opening of the lamp housing, so that the light from the light source board can completely enter the columnar light guide.

[0026] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a columnar light guide is arranged, and a plurality of strip light guides are embedded in the columnar light guide, which can not only increase the decorative performance of the columnar light guide, but also when irradiating, the light passes through the strip light guide, then passes through the columnar light guide, and then irradiates outward through the lamp housing, which can realize the lighting shape of the lines, improves the decorative effect of the lighting, and has strong applicability and good practicality.
