Abstract: A ceiling fan assembly includes a fan and a light-sensitive circuit for controlling an illumination level of a light as a function of an ambient illumination level surrounding the ceiling fan assembly by selectively controlling or fixing a conduction phase angle of an AC power signal provided to the light. The light-sensitive circuit includes a photocell, a phase control circuit and a cutoff circuit which prevents flicker at low illumination levels. The photocell is responsive to the ambient illumination level and has a conduction state. The conduction state changes in response to the ambient illumination level. The phase control circuit selectively varies or fixes a conduction phase angle associated with the AC power signal, which correspondingly determines a variation in the illumination level of the light.

Abstract: A light sensitive dimmer switch circuit for controlling the illumination level of a light as a function of the ambient illumination level surrounding the dimmer switch circuit by selectively controlling an AC power signal provided to the light includes a photocell and a phase control circuit. The photocell is responsive to the ambient illumination level and has a conduction state associated therewith. The conduction state changes, in response to the ambient illumination level, such that the photocell effectively exhibits either a substantially open circuit or a substantially short circuit. The phase control circuit selectively varies a conduction phase angle associated with the AC power signal which correspondingly causes a variation in the illumination level of the light.

Abstract: A lamp with improved safety features to avoid fire and burn hazards. The lamp includes an electrical circuit having a thermostat connected in series with the bulb of the lamp. The thermostat is mounted in close proximity to the lamp's bulb and, upon the ambient air temperature in the vicinity of the thermostat reaching a predetermined temperature, the thermostat effectively opens the electrical circuit, shutting the lamp off. Once power is turned off for a period of time, the thermostat resets and the lamp may be operated again. A protective guard is positioned over at least a portion of the bulb of the lamp to prevent accidental burning.

Abstract: An easy-assembly dual-pole floor lamp includes a first pole with top and bottom ends and a base portion which is secured to the bottom end of the first pole. The base portion has a lower second-pole-receiving region, and a second-pole-mounting member is secured to the first pole at a predetermined distance above the lower second-pole-receiving region of the base portion. The second-pole-mounting member has an upper second-pole-receiving region. The lamp also includes a second pole which has a top end and a bottom end. The top end is configured to mate with the upper second-pole-receiving region, and the bottom end is configured to mate with the lower second-pole-receiving region. The length of the second pole is adjustable over an adjustment range which extends at least between first and second values; the first value of the length is selected to permit easy insertion of the second pole between the upper and lower second-pole-receiving regions.
