The present invention relates to a multi-light-emitting area surface
light source and a vehicle light module, wherein the multi-light-emitting area surface
light source comprises a circuit board; an
LED lamp, which is arranged on the circuit board; a reflector grille, which is arranged on the circuit board, and the reflector grille comprises a plurality of phase-separated areas, wherein an
LED lamp is arranged at the center of each area, each
LED lamp is independently controlled, and the optical center distance L between two adjacent LED lamps and the height H of the reflector grille satisfy the formula: L / H=tan(δ / 2), wherein δ is the light output angle of the LED lamp after passing through a
diffusion film; the
diffusion film is arranged on the reflector grille and covers the LED lamp. The multi-light-emitting area surface
light source provided in the present application can realize the conversion from a
point light source to a surface light source with the least number of LED lamps, and the lighting and extinguishing of the LED lamp in each light-emitting area can be independently controlled, thus realizing the pixelated surface light source effect very economically; a thin
diffusion film is adopted, and no additional diffusant or an internal light distribution mirror mixed with a diffusant material is required, so that a better light uniformity effect can be achieved.
