Embodiment approach
[0056] In one embodiment, Figure 2A It is a schematic diagram of the cylindrical light-emitting element of the light-emitting diode light bulb device of the present invention before bending according to a selective change of this embodiment. The metal guide plate 40 can be bent along the dotted line L and then directly formed into a rectangular columnar body. In this way, when the columnar light-emitting element 30 has the LED elements 70 on multiple sides, it can provide various lighting angles. However, each independent metal guide plate 40 can also be completed into the above-mentioned rectangular columnar body through combination (such as welding or assembly).
[0057] In another embodiment, Figure 2B It is a schematic diagram of a selective variation of the columnar light-emitting element of the light-emitting diode light bulb device of the present invention according to this embodiment. The above-mentioned columnar light-emitting element 30 further includes a bearin...
