Title:
PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/067218
Kind Code:
A1
Abstract:
A projection device (1000), comprising a light source (100), an optical modulation assembly (200), and a lens (300). The light source (100) comprises a laser (10). The laser (10) comprises a bottom plate (101), a frame body (102), a plurality of light-emitting chips (103) and at least one pin assembly (104). The frame body (102) is arranged on the bottom plate (101) and defines an accommodating space (112) with the bottom plate (101). The frame body (102) comprises at least one fixed notch (1020). The pin assembly (104) comprises an insulator (1041) and at least one electrode pin (1042). The insulator (1041) is connected to the frame body (102) by means of the fixed notch (1020). The at least one electrode pin (1042) is spaced apart on the insulator (1041). The electrode pin (1042) comprises a first conductive layer (10421) and a second conductive layer (10422). The first conductive layer (10421) is located in the accommodating space (112) and is electrically connected to the light-emitting chips (103). The second conductive layer (10422) is located outside the accommodating space (112) and is electrically connected to the first conductive layer (10421) and an external circuit.
