| Zusammenfassung: | The invention discloses a light source device. The light source device comprises a tube shell, a transparent cover plate, a wavelength conversion device, a light source module and an annular reflecting part, the transparent cover plate, the wavelength conversion device, the light source module and the annular reflecting part are arranged on the tube shell in a covering mode, and a sealed space is formed by the tube shell and the transparent cover plate; the wavelength conversion device is arranged on the transparent cover plate; the light source module is located in the sealed space and used for emitting light beams. The annular reflection piece is located in the sealed space, comprises an annular reflection face and is used for reflecting the light beams to the wavelength conversion device. According to the light source device, the light beam emitted by the light source module is reflected to the wavelength conversion device through the annular reflection piece, circular light spots in Gaussian distribution |
