Light emitting systems and methods

An apparatus and method of operation of a low-current LED lighting circuit are disclosed. The invention utilizes high AC voltage input and unreduced voltage ripple component of the rectified DC power signal, which provides the ability to drive an LED load at high power factor at low current. The invention discloses both active and passive circuits to limit the peak current flowing to the LED and create a current source for the LED load. The proposed circuit increases reliability by optionally eliminating capacitor, inductor, and heatsink components while minimizing luminous flux fluctuations.

Apparatus and method of operation of a low-current LED lighting circuit

This invention is about a reliable light-emitting system and a method to make it. The light-emitting system is mounted on a carrier with a non-conductive adhesive such that at least one of the p-contact layer and n-contact layer of the light-emitting device is in direct contact with conductive patterns formed on the carrier.

A method for controlling gain in a network is provided. The method includes receiving signals for transmission over a network and adjusting the level of the received signals. The method further includes inserting an additional signal indicative of the level adjustment and transmitting the signals and the additional signal over the network. The method also includes extracting the additional signal after transmission over the network and compensating for the level adjustment based on the extracted signal.
