Abstract

A solar-powered illuminator, which includes an integrated light receiving and emitting device having a solar chip and a LED chip, a rechargeable battery and an Application-Specific Integrated Circuit (ASIC), is provided. A transparent encapsulant of the integrated light receiving and emitting device focuses the incident sunlight on the solar chip to generate a first voltage. The rechargeable battery is electrically connected to the integrated light receiving and emitting device and is charged by the solar chip in the first voltage. The ASIC is electrically connected to the rechargeable battery and the light receiving and emitting device, and it steps up the first voltage into a second voltage and drives the LED chip to emit light via the discharge of the rechargeable battery in the second voltage. Consequently, the solar-powered illuminator has the advantages of small size, compactness, simple integration, easy installation and cost-effectiveness.

Description

technical field [0001] The invention relates to a solar light emitting device, in particular to a solar light emitting device integrating a light receiving element and a light emitting element. Background technique [0002] With the advancement of technology, solid-state lighting sources, such as light emitting diodes (Light Emitting Diodes, LEDs), are increasingly The more cost-effective it is; all kinds of LEDs, such as red LEDs, blue LEDs, green LEDs, and white LEDs, can be used in many lighting applications according to different usage methods such as decoration, indication, display, and lighting. in the field of application. [0003] On the other hand, compared with the gradually shortage and expensive disadvantages of oil, solar energy has the advantage of being free and not exhausted, so it has been gradually used as a source of clean energy. For example, a gallium arsenide (GaAs), indium gallium arsenide (InGaAs), cadmium telluride (CdTe), aluminum gallium arsenide...
