Publication number: 20250128660Abstract: A light emitting device to be mounted on a mount surface of a vehicular compartment includes a housing including a first section having an air intake hole and a cooling fan and a second section having an air discharge hole and a light emitter. The light emitter includes a board member having a first surface that is opposite the mount surface and a second surface that is an opposite surface of the first surface and on which a light emitting element is mounted. The housing further includes a discharge cavity having the discharge hole, and a top wall and a bottom wall that are opposite each other. The top wall includes a cavity upper wall section near the discharge hole. The cavity upper wall section has an opposite surface facing the first surface of the board member and extending parallel to the first surface.Type: ApplicationFiled: December 30, 2024Publication date: April 24, 2025Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Motoki MAEKAWA, Ryosuke USAMI, Masahiro IRIE, Yohei ISHIZU, Mitsutaka SAKOH
