Document Type and Number:
WIPO Patent Application WO/2023/210678
Kind Code:
A1
Abstract:
The present invention provides a vehicle lamp that can form a radiance pattern having a desired brightness distribution while also efficiently using light from a light source, and in which an optical part can be attached with good precision. The vehicle lamp includes: a first light source and a second light source; a collecting lens for collecting light therefrom; a shielding member that passes light collected thereat through a radiating slit; and a projecting lens that forms a radiance pattern with that light. The collecting lens has a first lens portion that corresponds to the first light source and a second lens portion that corresponds to the second light source, the radiating slit has a near-side slit portion that corresponds to a near-side radiance design of the radiance pattern and a far-side slit portion that corresponds to a far-side radiance design of the radiance pattern, the first lens portion is disposed facing the far-side slit portion, and the second lens portion is disposed facing the near-side slit portion. Also, a collecting lens member, the shielding member, and a projecting lens member are fixed to a supporting member such that a collecting lens frame and a shielding frame overlap in an optical axis direction.
