Abstract

A headlamp module comprises a connecting base, a substrate, and at least two edge-type light emitting diode (LED) units. The at least two edge-type LED units are mounted to opposite surfaces of the substrate facing away from each other. Each edge-type LED unit comprises an LED chip, a wavelength converting layer, and a light reflecting layer. The LED chip comprises a bottom surface, a light emitting surface facing away from the bottom surface, and first sidewalls. The wavelength converting layer covers the light emitting surface and the first sidewalls. The wavelength converting layer converts emitted light to a desired range of wavelengths. The light reflecting layer reflects the converted light toward the second sidewalls, thus expanding the angle and brightness of light around the headlamp module and avoiding an unlit or dark area immediately around the headlamp module.
