Title:
LASER
Document Type and Number:
WIPO Patent Application WO/2023/124344
Kind Code:
A1
Abstract:
A laser (10), comprising: a bottom plate (101), multiple light-emitting chip sets (103), at least one frame (102), at least one first electrically conductive layer (1023), and at least one second electrically conductive layer (1024). The at least one frame (102) comprises a frame body (1020), a first step (1021), and a second step (1022). A portion of an end of the frame body (1020) near the bottom plate (101) protrudes in a direction toward the multiple light-emitting chip sets (103), forming the first step (1021). Another portion of the end of the frame body (1020) near the bottom plate (101) protrudes in a direction away from the multiple light-emitting chip sets (103), forming the second step (1022). The at least one first electrically conductive layer (1023) is disposed on the first step (1021), and is connected to the multiple light-emitting chip sets (103). The at least one second electrically conductive layer (1024) is disposed on the second step (1022). The at least one second electrically conductive layer (1024) is connected to a corresponding first electrically conductive layer (1023), and is connected to an external power source.
