An LED lighting device is provided which is capable of being connected to a network and being controlled by a host computer also connected to the network. The lighting device has several lifespan expanding features such as including several extra LEDs such that as the LEDs of the lighting device degrade over time more LEDs can be turned on thus allowing a constant luminosity to be maintained.

Illumination device for a vehicle comprises a first lamp module (30) and a second lamp module (40), each having a number of light-emitting diodes (31, 41). The second lamp module surrounds the first lamp module. The lamp modules are staggered in relation to each other and are separately fixed so that they can be individually replaced. Preferred Features: The second lamp module is optically set back behind the first lamp module.

An apparatus is provided for use in a device having a battery and one or more power consuming circuit boards that are powered by the battery. The battery connector includes one or more electrical conduits and a housing. Each electrical conduit includes a battery contact, a first circuit board contact, and as second circuit board contacts. The battery contact is for contacting the battery and forming an electrical connection therebetween. The first and second circuit board contacts are for contacting the one or more circuit boards and forming electrical connections therebetween. The housing retains the electrical conduits.

An electrical appliance housing including a hard plastic housing body defining a switch-actuating aperture. The aperture is sealed with a soft plastic membrane. An actuating button is fastened to a hard plastic base that is bonded to the membrane.

An explosion-proof fluorescent lamp (10) comprises a battery (11) for emergency current supply and a heating means to warm the lamp or the battery

The invention relates to methods of manufacturing gas-discharge electron lamps, and neon tubes in particular. According to the invention, it is proposed, prior to carrying out vacuum treatment of the internal space of an electron lamp (1), to mount at least one of said glass capsules (2) in exhaust tube (5), in close proximity to an exposed electrode in such manner that the opening provided in metal container (4) is facing the working area of the lamp (1). Upon carrying out vacuum treatment and filling the internal space with an inert gas, the portion of exhaust tube (5) that contains capsule (2) disposed within metal container (4) is separated from evacuation unit (10), and this area is subjected to the local effect of a high-power electromagnetic radiation, thereby causing substantially instantaneous heating of metal container (4), which results in a rupture of glass capsule (2) and intense evaporation of the liquid mercury, thereby resulting in a directional flow of pure mercury vapor, which flow rapidly fills up said internal space of the tube through the opening provided in metal container (4). Such method permits to provide environmentally safe production and to eliminate contamination of mercury inside the working space of a lamp, which in turn allows carrying out precise dosing and introduction of calculated minimal amounts of mercury. In addition, the inventive method does not require application of special electrodes and might be used in any mass manufacture of commercial products, and neon tubes in particular.
