摘要: A photo-coupler is provided. The photo-coupler comprises a light emitting chip, a light-sensing chip, a light-transmissive inner encapsulant package and an outer package. Both the light emitting chip and the light-sensing chip face the same direction, while the light-sensing chip receives a light beam emitted by the light emitting chip. The light-transmissive inner encapsulant package encloses the light emitting chip and the light-sensing chip, while the outer package encloses the light-transmissive inner encapsulant package. An interface is formed between the light-transmissive inner encapsulant package and the outer package for reflecting the light beam. A reflective curve surface adjacent to the light emitting chip is formed on the interface of the light-transmissive inner encapsulant package for reflecting and converging the first portion of the light beam to the light-sensing chip.

摘要: An illumination device. A control circuit module is disposed in a first base. A second base is detachably connected to the first base. A heat-dissipation module is disposed in the second base and is electrically connected to the control circuit module. A first fastening ring fastens the first base with the second base. A third base is detachably connected to the second base. A light source module is disposed in the third base and is electrically connected to the heat-dissipation module. A second fastening ring fastens the second base with the third base.
