Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] This utility model relates to a light projection structure for a bulb lamp, including a light-transmitting tube 100 and a light source 300.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the light-transmitting tube 100 is cylindrical and can be integrally molded from a light-transmitting material. The light-transmitting tube 100 has multiple light-projecting sections 200, each having a light-emitting side 210 and a mounting side 220. The light-emitting side 210 faces the outside of the light-transmitting tube 100, and the mounting side 220 faces the inside of the light-transmitting tube 100; that is, the light-emitting side 210 is located on the outside of the light-transmitting tube 100, and the mounting side 220 is located on the inside of the light-transmitting tube 100. The light-emitting side 210 has several first light-projecting areas 230, each distributed on the outside of the light-transmitting tube 100, and each first light-projecting area 230 is recessed from the light-emitting side 210 towards the mounting side 220. The opening of each first light-projecting area 230 faces the outside of the light-transmitting tube 100. Each first light-projecting area 230 includes a first main light surface 231 and a first side light surface 232. Each first side light surface 232 in each first projection area 230 is arranged around the first main light surface 231. The first projection area 230 is shaped like a polygonal "recess" on the projection part 200. The light source 300 can be a light strip, light panel, etc. The light source 300 is mounted on the mounting side 220. Alternatively, the mounting side 220 may have a slot 221. The light source 300 is inserted into the slot 221 for quick fixation on the mounting side 220. The light source 300 generates light through the lamp beads 310, and the light shines from the mounting side 220 toward the light-emitting side 210. The light is projected outward through the projection part 200. When light passes through each of the first projection areas 230, some light shines directly outward through the first main light surface 231, while some light is refracted through each of the first side light surfaces 232. Based on the design angle of each first side light surface 232, the light, under the refraction of the first side light surface 232, forms a certain range of outward diffusion effect within the corresponding first projection area 230. This reduces or even eliminates the dark areas formed between the LED beads 310 inside the light source 300. When emitting light, the individual LED beads 310 are not visible from the outside of the light-transmitting tube 100. The combined effect of multiple first projection areas 230 increases the overall light illumination range of the light-transmitting tube 100.

[0029] Among them, such as Figure 4 and Figure 5As shown, the first main light surface 231 is a polygonal plane. The first main light surface 231 can be a polygonal plane such as a triangle, quadrilateral, or pentagon. In this embodiment, the first main light surface 231 is set as a square plane. Each side of the first main light surface 231 extends obliquely to form a first side light surface 232. The first side light surface 232 and the first main light surface 231 form an obtuse angle. The sides of adjacent first side light surfaces 232 in the same first projection area 230 are connected. The first projection area 230 is flared from the mounting side 220 towards the light-emitting side 210. Light rays pass directly outward through the first main light surface 231, and the light rays are refracted through each first side light surface 232 to expand the illumination range. The light rays from two adjacent first projection areas 230 can overlap through the first side light surfaces 232, so that no shadows appear between adjacent first projection areas 230, achieving or approaching the effect of a shadowless lamp.

[0030] In this embodiment, at least two sequentially distributed light-emitting sides 210 are provided on the same light-projecting section 200. Two, three, or more light-emitting sides 210 may be provided on a single light-projecting section 200. In this embodiment, as shown... Figure 4 and Figure 5 As shown, a projection section 200 has three light-emitting sides 210. The three light-emitting sides 210 are distributed sequentially along the circumference of the light-transmitting tube 100. Adjacent light-emitting sides 210 on the same projection section 200 form an obtuse angle. Spatially, the three light-emitting sides 210 on the same projection section 200 are similar to three sequentially connected sides of a hexagonal prism, with adjacent light-emitting sides 210 forming a 120° angle. Five projection sections 200 are provided on the light-transmitting tube 100. Adjacent projection sections 200 compensate for each other's light through the closest first projection area 230. The first projection areas 230 on the same projection section 200 compensate for each other's light, creating a shadowless lamp effect along the circumference of the light-transmitting tube 100. In this embodiment, the projection section 200 extends in a long strip shape. Each first projection area 230 is distributed sequentially along the length of the projection section 200. A projection section 200 has three light-emitting sides 210, which extend parallel to each other along the length of the projection area. The length of the projection section 200 is the axial direction of the light-transmitting tube 100. The light source 300 is a lamp bar. After the lamp bar is installed on the mounting side 220, the lamp beads 310 on the lamp bar are distributed sequentially along the length of the projection section 200.

[0031] Furthermore, such as Figure 3 and Figure 5As shown, the interior of the light-transmitting tube 100 is hollow, forming a cavity 110. Multiple light-projecting sections 200 are distributed sequentially at intervals along the circumference of the cavity 110. In this embodiment, the light-transmitting tube 100 has five light-projecting sections 200, which, when viewed from above, form a regular pentagonal arrangement. The mounting side 220 faces the cavity 110, which is connected to the outside of the light-transmitting tube 100 through the gaps between the light-projecting sections 200. The light source 300 is mounted on the mounting side 220, and the cavity 110 and the gaps between the light-projecting sections 200 accelerate airflow and effectively dissipate heat.

[0032] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the light-transmitting tube 100 has an open end 120 and a closed end 130 positioned opposite each other. The axial / length direction of the light-transmitting tube 100 is vertical. The upper end of the light-transmitting tube 100 is the open end 120, and the lower end is the closed end 130. The light source element 300 is inserted into the mounting side 220 from top to bottom through the open end 120. The closed end 130 is provided with an end plate 140, which is made of transparent material and allows light to pass through. The end plate 140 connects the lower ends of each light-projecting part 200. A plurality of second light-projecting areas 150 are provided on the end face of the end plate 140 away from the open end 120, i.e., a plurality of second light-projecting areas 150 are provided on the lower side of the end plate 140. The second light-projecting areas 150 are recessed from the end face of the end plate 140 towards the open end 120. Some light can pass through the end plate 140 and shine downwards. In conjunction with the second projection area 150, light passing through the end plate 140 can be refracted, thereby increasing the illumination range at the bottom of the light-transmitting tube 100. Specifically, the second projection area 150 includes a second main light surface 151 and a second side light surface 152. The second main light surface 151 is a polygonal plane, which can be a triangular, quadrilateral, pentagonal, or other shaped plane. In this embodiment, the second main light surface 151 is a triangular plane. The three sides of the second main light surface 151 extend obliquely to form the second side light surface 152. The second side light surface 152 and the second main light surface 151 form an obtuse angle. The sides of adjacent second side light surfaces 152 in the same second projection area 150 are connected. Light shines directly downward through the second main light surface 151, and then is refracted through each of the second side light surfaces 152. According to the angle of the second side light surface 152 relative to the second main light surface 151, the light is diffused within a certain range, increasing the bottom illumination range.

[0033] Among them, such as Figure 1 and Figure 2As shown, it also includes a threaded connector 400. Each light source element 300 is integrated on a flexible circuit board, and the flexible circuit board and the threaded connector 400 can be electrically connected via wires or guide plates. The threaded connector 400 is mounted on the open end 120. Power is supplied through the threaded connector 400 to connect to an external threaded lamp holder.
