Beschreibung
Zusammenfassung:	The lighting device comprises a laser light source, a diffusion element and a wavelength conversion device, the diffusion element is located between the laser light source and the wavelength conversion device, the laser light source is used for emitting laser, the diffusion element is used for scattering the laser, and the laser scattered by the diffusion element forms laser spots on the wavelength conversion device. The wavelength conversion device comprises a substrate and a wavelength conversion layer arranged on the substrate, the wavelength conversion layer corresponds to the laser spots, the ratio of the area of the wavelength conversion layer to the area of the laser spots is 0.8-1.2, and the wavelength conversion layer is used for at least partially converting received laser into fluorescent light. According to the scheme of the utility model, the area of the laser spot on the wavelength conversion device is approximately the same as the area of the wavelength conversion layer, so that the fluorescenc
