Description

Technical Field

[0001] The invention relates to an automobile lamp bead with a full-angle rhombus-shaped light-transmitting body and a processing mold for processing the lamp bead, belonging to the field of automobile lamps. Background Art

[0002] Daytime running lights (DRLs) are lamps that make it easier to identify a vehicle when it is driving during the day. They are installed on the front of the vehicle body to let others know that a car is coming. They are a kind of signal light. At the same time, in actual use, due to the dazzling light of DRLs, they usually also play a decorative role. The lamp beads of existing DRLs are generally LED lamp beads. Since the individual LED lamp beads are small, multiple LED lamp beads are generally arranged in a certain shape into strips, arcs or rings during installation, so that the DRLs are more beautiful when they are lit. When installing multiple LED lamp beads, the light source module needs to be matched, which is not only troublesome to install, but also increases the cost. In addition, when LEDs emit light, lenses are required to enhance the transparency of the light, but lenses cannot be installed on DRLs due to limited space. Summary of the invention
