Abstract
An LED light source of a mini-projector optical system comprises an aluminum substrate and an LED chip. A groove is arranged on the aluminum substrate, a reflection surface is formed on the lateral wall of the groove, the LED chip is arranged inside the groove, a condensing lens is arranged on the groove, a heat dissipating layer is arranged on the bottom surface of the aluminum substrate, and a heat dissipating pipe is arranged in the heat dissipating layer. Both the LED chip and the condensing lens can be arranged inside the groove of the aluminum substrate, thereby greatly reducing occupied space of components composing the light source and integrally decreasing the volume of the optical system. The lateral wall of the groove can be used as a reflector to reflect rays on the periphery of the LED chip back and greatly increase use rate of the light. The heat dissipating layer and the heat dissipating pipe arranged on the bottom surface of the aluminum substrate are better in heat dissipation effect, thereby allowing an LED chip with larger power to be installed to improve luminosity of the light source.
