A system suitable for use as a restaurant and nightclub receipt reader is provided. The system includes a translucent plate. The system also includes a light emitting diode (LED) configured to provide illuminating light into the translucent plate. The system further includes a battery designed to provide power to the LED. The system includes an on/off switch arranged to turn the LED on and off. The system also includes a clip positionable on a top upper front side of the translucent plate and structured to be utilized to retain a receipt against the front side of the translucent plate allowing a user of the system to effectively view the receipt in low ambient light conditions. Additionally, the system is configured wherein the LED, the battery, the on/off switch, and associated control circuitry for controlling the LED are located under a bottom surface of the clip.

Improvements a portable elevated lighting system that uses LED lighting elements for illumination. The LED lights are selected based upon the light transmission angle so the fewest number of lighting elements are needed to provide an even flood or focus of light from the system. A reflector works as a heat sink to remove heat from the LED lights and extend the operation life of the LED's. Thermal paste and or a thermal pad is used between the LED lighting element and the frame to conduct sufficient heat away from the LED element. Two versions are shown as a stadium light and as a circular flood light that provides lighting without shadows or bright areas. The system can be operated from a generator or solar for charging batteries so the lighting can operate self-contained without producing noise.

A portable light may comprise: a light body having an internal cavity configured to receive a rechargeable power source, having a keying feature, and having an opening through an exterior wall in a predetermined location relative to the keying feature; and a light source. A rechargeable power source has a charging connector and a keying feature in predetermined locations that when the keying feature thereof engages the keying feature of the internal cavity, the charging connector thereof is aligned with the opening through the exterior wall of the light body. Thus an external source of charging power can be connected through the opening in the exterior wall directly to the charging connector of the rechargeable power source for recharging the rechargeable power source while it is in the portable light.

An indicator circuit for an emergency light, including: a charging circuit, in connection with a positive terminal of a lithium battery and configured to charge the lithium battery; a battery protection circuit, in connection with a negative terminal of the lithium battery and configured to provide protection against overvoltage and overcurrent of an electrical signal output by the lithium battery; a main control circuit, in connection with the negative terminal of the lithium battery and configured to compare the electrical signal output by the lithium battery with a reference voltage signal and output a control signal; and a drive circuit, in connection with the main control circuit and an indicator light, and configured to drive the indicator light to illuminate according to the control signal and turn off the indicator light in case of abnormal conditions.

The present invention relates to an ambiance lighting system that more than one of a translucent panel aligned and connected together to form a perimeter having a top edge, and an interior region. A light control panel comprises one or more light-emitting diode (LED), and a power source. One or more of a sleeve have an open edge, the light control panel slides into the open edge and is retained in the sleeve, the sleeve is secured across the top edge of the translucent panel, the light control panel is orientated within the sleeve so that the LED illuminate the interior region projecting light through the translucent panel creating an ambiance lighting effect. Exemplary embodiments include a handle for carrying, use of Fresnel lenses, and creating a kit of ambiance lighting system parts that a consumer can assemble.
