| 摘要 |
The present invention relates to power supplies and in particular to an electronic power supply that is mounted to a printed circuit board and can be used to power electronic circuits and devices. Disclosed is a power supply which includes a photoluminescent light source. The photoluminescent light source generates light in response to receiving input power. One or more than one photovoltaic device is in optical communication with the photoluminescent light source, and generates output power in response to receiving light from the photoluminescent light source. The amount of output power generated by the one or more than one photovoltaic device is greater than the amount of input power received by the photoluminescent light source. In some embodiments the photoluminescent light source includes a light-emitting device and a photoluminescent material, each of which is embedded in an optical coupling material.
