Abstract: An LED luminaire is provided with a light emitting module composed of plural kinds of LEDs emitting lights of different colors, a lens unit having a lens for diffusing the mixed-color light from the light emitting module, a light output controller for controlling electric current fed to each of the LEDs, and a light sensor for sensing the light from the light emitting module. The light output controller performs feedback control on the electric current fed to each of the LEDs based upon light levels of the sensed light, so that the light emitted from the light emitting module has desired chromaticity. The lens unit contains a light guide for guiding the light from the lens to the light sensor and can guide the light from the light emitting module to the light sensor with a high efficiency.

Abstract: An antenna with a lighting function includes an accommodation body, a light-transmissive head, a light source, and an antenna component. The accommodation body has an accommodation space therein, and the light-transmissive head is disposed on the accommodation body and allows lights to transmit through. The light source is disposed within the light-transmissive head, and emits a light that is transmitted out of the light-transmissive head. Finally, the antenna component is accommodated within the accommodation body, for transmitting wireless signals and for lighting.

Abstract: A waterproof Christmas light bulb includes a connection tube formed on top of the socket and having a diameter smaller than a diameter of the socket so that a step is formed at a joint between the socket and the connection tube. A bulb is partially received in the connection tube. Two wires are oppositely formed on a side of the bulb, and a dividing plate is integrally formed on a bottom of the bulb. An O ring rests on and is supported by the step. An enclosure is securely connected to the connection tube by a securing device so that the O ring is securely clamped between the enclosure and the step of the socket to complete a waterproof engagement between the enclosure and the socket. A plug is received in the socket to have a waterproof engagement with the cables and the inner periphery of the hollow socket.

Abstract: A vehicle lamp has light sources having light emitting diodes that are vertically and horizontally disposed in the form of a square. A first LED group is disposed in the central position of the light source and is turned on in the tail lamp lighting mode. A second LED group surrounds the first LED group, and is turned on together with the first LED group in the stop lamp lighting mode. Thus, the light source appears as if the LEDs became luminous around the central position of the light source in any lamp lighting mode.

Abstract: A portable drakroom safelight which incorporates several features which enhance its usefulness in a darkroom. The portable safelight includes a lamp, a safelight filter, rechargeable batteries, a light sensor, and control means. The safelight filter filters all light produced by the lamp, thus making the safelight safe for use in a darkroom and with photosensitive materials. A surface mounting bracket or stand supports the portable safelight and includes a transformer for converting household electric current into low voltage direct current suitable for use by the portable safelight. When the portable safelight is removed from the mounting bracket it automatically switches to operate from the rechargeable batteries and its illumination level is automatically reduced. The lamp is automatically turned off or on when the light sensor detects the presence or absence of ambient white light.

Abstract: A darkroom safelight filter assembly for a TV set comprises a filter screen tinted to exclude damaging light rays for photographic materials, having a bracket thereon mounting a block of sponge rubber supported on the top wall of the TV set. The filter screen depends from the bracket, is spaced from the TV screen and includes a continuous strip of resilient light sealing sponge rubber of rectangular shape for snug sealing registry with the TV casing surrounding the TV screen.
