摘要： A switching power supply circuit has a control circuit for current-mode on-off control of a primary switch connected to an inductor in a voltage boost topology for operation in boundary-conduction mode. The time at which the primary switch is opened is determined by magnitude of current flowing through the primary switch together with the instantaneous voltage present on an AC input to the power supply circuit. The time at which the primary switch is closed is determined by demagnetization of the inductor. An improvement to the foregoing switching power supply circuit comprises a maximum- on-time enforcement circuit to limit the maximum possible primary switch on-time to a predetermined maximum period of time. The enforcement circuit provides a signal to the control circuit to cause termination of the primary switch on-state if and only if the primary switch has been turned on for more than the predetermined maximum period of time.

摘要： An elongated LED lighting arrangement comprises an elongated light pipe with homogeneous optical material between first and second ends. In an exemplary embodiment, an LED provides blue light to the light pipe via a first dichroic mirror tuned to pass blue light. Down-converting means on sidewall of the light pipe, tuned to receive blue light, absorbs blue light from the LED and to emit lower-energy light outside of the light pipe at respectively higher wavelengths. Light-extracting means on the sidewall extract from the light pipe some blue light without changing the wavelengths of the foregoing light. Light from the down-converting means and the light-extracting means are combined to provide a composite color. The first dichroic mirror receives some light emitted by the down-converting means and reflects back into the light pipe more than 80 percent of the light received by the mirror.

摘要： Disclosed is a method of passivating and reducing reflectance of a silicon photovoltaic ceil. The method includes the step of providing a silicon wafer of a solar eel! having a major surface. A passivation layer of silicon nitride is applied on at least 98 percent of the major surface through a vacuum deposition process. An index- matching film structure, different from silicon nitride, is applied on top of the passivation layer. The index matching film structure provides the majority of the antirefiective property of the combination of the passivation layer and the index matching film structure.
