Abstract: A lighting fixture display system and method including a light support member for supporting truncated floor-based lighting fixtures and a rail member. The light support members have shelf structures and brackets and are mounted on or attached to the rail member, which in turn may be mounted on or attached to a display wall. The rail members and light support members may be configured to form a display system having multiple horizontal display rows. The display system makes efficient use of retail space, is easy to build, and can be varied to enable various different display configurations as well as allow easy replacement or repair of lighting fixtures.

Abstract: A safety switch for a lamp is disclosed. The safety switch comprises a pair of electrodes having cylindrical shapes. Each electrode comprises an internal face with a conical cavity therein. The electrodes are arranged so that they are adjacently mounted with an aperture formed between the two conical cavities. In addition, there is a metal ball placed within the conical cavity. The metal ball forms a connection or disconnection of the electrodes. In one embodiment of the invention, the electrodes are horizontally mounted, and when the lamp is displaced from an upright position, the ball rests along the aperture formed between the two electrodes, thereby providing a connection of the electrodes and power and luminescence to the lamp. When the lamp is displaced from the upright position, the ball moves away from the aperture, thereby disconnecting the electrodes and power and luminescence to the lamp.

Abstract: A lamp with a temperature-controlled automatically protecting circuit which includes a temperature induction circuit and a sampling circuit with its input end to connect with an output end of the temperature induction circuit, wherein the temperature control automatically protecting circuit further includes: a comparing circuit which has an input end to connect with an output end of the sampling circuit and when a positive voltage drop across the sampling resistance of the sampling circuit is lower than a reference voltage, the comparing circuit will have a high electrical level output; a trigger circuit which has an input end to connect with an output end of the comparing circuit and a thyristor which can be triggered by the high electrical level output of the comparing circuit to have the trigger circuit in the on state; and a maintaining circuit which has a capacitance in parallel with the thyristor in the trigger circuit and which, after being in series with a resistance, have a low electric level output

Abstract: A halogen torchiere lamp diffuser apparatus has a reflective element situated directly under the halogen bulb within the lampshade. The reflective element has an elongated projection with a trapezoidal or triangular cross section and with a minimal top surface such that light, and thereby heat, is diffused outward towards the edges of the lampshade and not concentrated immediately above the bulb. In addition, the reflective element has a flat section extending outward from the projection and having curved cutouts therein to allow air to pass the bulb and convect heat away from the bulb. The apparatus further has a glass shield spaced at a critical distance above the bulb and its cylindrical glass cover, thereby allowing heat to be convected away from the bulb. The apparatus can be adapted as a "retrofit" apparatus that can be installed to an existing halogen torchiere lamp by a consumer.

Abstract: A computer keyboard light comprises, in a first embodiment, at least one small upright lamp unit mounted to a flat plate that is secured to the underside of the computer keyboard or PC monitor. The lamp arms are telescopeable and are rotatable by rachet connections to allow for adjustment of the lights. The arms could also be formed of an internal structure that allows them to be twisted or adjusted into different shapes and positions. In another embodiment, the computer keyboard light further comprises a small lamp unit mounted to a small rectangular plate that is adhered to the side of the PC monitor in order to illuminate either the keyboard, the monitor screen or a copy holder.

Abstract: A halogen torchiere lamp comprises a grid-like guard arranged across the lampshade opening for preventing flammable material from making contact with the hot glass shield of the bulb or the bulb itself. A temperature sensor is installed within the lampshade near the bulb to sense the rise in ambient temperature within the lampshade should its opening be covered by any material. The sensor comprises a thermostat that de-energizes the bulb when the sensed ambient temperature reaches a predetermined value. The sensor may also comprise a thermistor that operates the dimmer switch of the lamp to dim the bulb when the sensed ambient temperature reaches a predetermined value. The sensor may further comprise a photocell-powered thermistor that varies the bias of a transistor, which in turn causes the bulb to dim, thereby lowering the ambient temperature within the lampshade.
