Title:
LIGHT SOURCE AND COLLIMATING LENS INTEGRATED DEVICE, LIGHTING DEVICE AND PROJECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/104260
Kind Code:
A1
Abstract:
A light source and collimating lens integrated device, a lighting device and a projection apparatus. The light source and collimating lens integrated device comprises a shell (3); and a support (2) arranged in the shell (3), wherein the support (2) has a cavity; a first mounting part and a second mounting part are formed on an inner wall thereof, are coaxially arranged, and are machined to form a rotation body contour; a first collimating lens (4) is snap-fitted to the first mounting part; a second collimating lens (5) is snap-fitted to the second mounting part; and a light source chip (1) is arranged at one end of the support (2), and light emitted by the light source chip is output after passing through the first collimating lens (4) and the second collimating lens (5). A machining process is used to treat the support (2) to form a mounting station which corresponds to the collimating lenses (4, 5) and has the rotation body contour, so as to achieve hole-axis matching between the support (2) and the collimating lenses (4, 5), namely, the axis of a hole of a rotation body of the support (2) coincides with the axis of the collimating lenses (4, 5), thereby effectively eliminating the accumulative tolerance of assembly of the collimating lenses (4, 5), and improving the coaxiality between the collimating lenses (4, 5).
