A reflecting-type blue laser lighting assembly relates to the technical field of lighting. The lighting assembly has a multilayer structure and includes, successively from bottom to top, a luminescentlayer, a substrate, a light beam scattering layer, and a high-reflecting aluminum plate. The luminescent layer, the substrate, the light beam scattering layer and the high-reflecting aluminum plate are tightly connected in a sintering manner. The luminescent layer is a glassy state substance containing fluorescent powder. The substrate is alumina, zinc oxide or quartz, of which the surface is coated with a film. The light beam scattering layer is a glassy state substance having micropores, which is composed of low-melting point glass powder and hollow alumina. The ratio of thicknesses of thelight beam scattering layer, the substrate and the luminescent layer is (1:10:1) - (2:5:2). The wavelength range of the blue laser is 420 to 480 nm. The surface, coated with the light beam scatteringlayer slurry, of the substrate is placed above the high-reflecting aluminum plate.
