Abstract: A lighting system and components are described for a lighting assembly, including a socket having a socket body and an electrical connector with a seal in the socket to seal around a light source. The socket is preferably configured to be independent of the mounting arrangement for the lighting assembly. An insulator is also disclosed for a lamp such as a fluorescent lamp having a body which protects the contact on the lamp so as to form a recessed lamp conductor. The combination of a socket and lamp insulator is also disclosed for providing a socket and insulator assembly for reducing the possibility of injury or damage due to high open circuit voltage, environmental effects and the like. Additionally, a lighting assembly is disclosed incorporating the insulator, socket and mounting arrangements.

Abstract: A socket for a lighting assembly includes a socket body defining an enclosure such that a lamp with a pin contact can extend into the enclosure. Electrical connectors extend away from the enclosure in a second direction. The body includes a wall extending away from the enclosure past the electrical connectors and is spaced from the connectors to allow access to the connectors, and a further wall between the electrical connectors. The further wall can provide an insulating barrier between the connectors. The connectors may be cylindrical. The wall extending away from the enclosure may include a cap covering the wall, and one or more conductors can pass underneath the cap to connect to the electrical connectors for powering the lamp.

Abstract: A light source for illuminating an area includes a cold cathode light source, and input and an output, and a converter coupled to the light source. The converter changes the current from an input alternating current supply to a lamp alternating current supply suitable for operating the lamp, for example from utility line voltage and current and changing it to an oscillating direct current supply. A display case such as a refrigeration unit may include an alternating current supply and a light source for illuminating an area within the display case. A current converter is coupled between the alternating current supply and the light source for changing the current from the supply at one voltage and frequency to a second voltage and a second frequency. In one preferred form, the light source is a cold cathode lamp at about 8500 Kelvin to include more blue light.
