A lighting control device includes: a first wireless communicator that wirelessly communicates with a lamp; first memory that stores identification information identifying the lighting control device; a first controller that transmits a control command for controlling the lamp to the lamp via the first wireless communicator; an operator interface suspended under its own weight; and a power generator that is connected to the operator interface, generates power from mechanical energy produced by the operator interface being moved in a predetermined direction, and supplies the power to the first controller, the first memory, and the first wireless communicator. When the operator interface is moved and the first controller receives the power, the first controller reads the identification information from the first memory, transmits the identification information and the control command to the lamp via the first wireless communicator, and controls the lamp.

An LED light bulb includes a bulb shell, a bulb base, a stem, conductive supports, an LED filament, and a supporting arm. The bulb base is connected to the bulb shell. The stem is connected to the bulb base. The conductive supports are connected to the stem. The LED filament includes a filament body and two conductive electrodes. The conductive electrodes are at two ends of the filament body and connected to the conductive supports. The filament body is around the stem. The supporting arm is connected to the stem and the filament body. In a height direction of the LED light bulb, H is a distance from a bottom to a top of the bulb shell. A first height difference is defined between the two conductive electrodes and is from 0 to 1/10H. The filament body is curved to form a highest point and a lowest point. A second height difference is defined between the highest point and the lowest point. The first height difference is less than the second height difference.

An electronic lamp holder with an improved structure includes a lamp holder whose upper part protrudes upwards to form a loading part, a battery mounting bin is designed in the loading part, a bin cover is on the bottom surface of the lamp holder for covering the battery mounting bin; a luminous body and a circuit board and a button switch for controlling the same are arranged on the loading part; the edge of the lamp holder extends upwards to form a blocking edge part and extends towards the outside to form a blocking part, a cylindrical locating sleeve is on the blocking edge part, an axle hole penetrating the locating sleeve is formed in the middle, a notch is formed in the outside face of the locating sleeve, a locating piece is arranged in the axle hole of the locating sleeve and rotates around the axle hole.

In one embodiment, a light emitting device includes a lighting element located in a housing, wherein the housing is formed from a plastic composition including, for example, a polycarbonate formed from reacting, in the presence of a transesterification catalyst, a diaryl carbonate ester and a bisphenol A, wherein the bisphenol A has a sulfur concentration of 1 ppm to 15 ppm, based upon a weight of the bisphenol A; and a conversion material wherein the conversion material includes an inorganic material that converts radiation of a certain wavelength and re-emits of a different wavelength; wherein after the conversion material has been exposed to an excitation source, the conversion material has a luminescence lifetime of less than 10.sup.−4 seconds when the excitation source is removed.

Illuminating devices are disclosed having plastic light-transmitting article(s) formed from a thermoplastic composition including a polycarbonate having repeating structural carbonate units according to the formula: ##STR00001##
in which at least 60 percent of the total number of R.sup.1 groups contain aromatic moieties and the balance thereof are aliphatic, alicyclic, or aromatic. The composition also includes an epoxy additive having at least two epoxy groups per molecule and a phenolic diphosphite derived from pentaerythritol. The thermoplastic composition exhibits a dE (2000 hrs.) value of less than 1.5 after 2000 hours of heat aging at 130° C., measured according ISO 11664-4:2008(E)/CIE S 014-4/E:2007 using CIE illuminant D65 and a 2.5 mm thick molded plaque of the thermoplastic composition.

A light-emitting diode (LED) light bulb includes an outer housing assembly, an inner housing assembly, an LED circuit board and a lamp cap. The outer housing assembly has a non-metallic outer shell and an inner shell affixed to an inner wall of the outer shell. The inner housing assembly is mounted inside the outer housing assembly through a lower opening of the outer housing assembly and is non-metallic and elongated with one end thereof securely connected with the base. The LED circuit board is mounted on a top of the LED mounting disc. The lamp cap is non-metallic and covers the upper opening of the outer housing assembly. Because the outer housing assembly and the lamp cap enclose the LED circuit board therein, users do not easily get an electric shock when holding the outer housing assembly or the lamp cap upon mounting or dismounting the LED light bulb to or from an LED lamp holder.

In a first aspect of the present invention, a lighting device (100) includes a first light emitter (1) that includes a first light-emitting element (10) with a p-n junction (10g), and a first side cover (11) partly covering a peripheral side surface (10c-10f) of the first light-emitting element (10); a second light emitter (2) that includes a second light-emitting element (20) with a p-n junction (20g) and a second side cover (21) partly covering a peripheral side surface (20c-20f) of the second light-emitting element (20), and the first light emitter (1) and the second light emitter (2) are disposed to face each other at uncovered side portions (10c, 20c) that are uncovered by the first side cover (11) and the second side cover (21). It is disclosed that the first side cover (11) covers a quarter or more area of the peripheral side surface (10c-10f) of the first light-emitting element (10).
