  • Publication number: 20060050514
    Abstract: A lamp has an at least partially transparent globe and a base carried on the globe, forming a passive heat-dissipating sink, and fittable in a socket. An LED is fitted to an inner surface of the base. Heat-generating driver circuitry connected to the LED is in heat-conducting contact with the base.

  • Patent number: 6893143
    Abstract: The invention relates to a lamp, in particular, a lounge, table, or pocket lamp with a lamp head (13), comprising a light source (16), arranged in a hollow reflector (17), which extends with the plug-in, or terminal contacts thereof, through an opening in the rear of the hollow reflector. According to the invention, the light source is a light diode (16). The opening in the hollow reflector (17), lies very close to the outline of the cover of said light diode, such that the light diode is centralised and longitudinally fixed in position, relative to said hollow reflector. The hollow reflector has a reflector piece, surrounding the light emitting chip of the light diode; which is at least essentially conical in shape.

  • Publication number: 20040252515
    Abstract: The invention relates to a lamp for use in a living space, especially a table or floor lamp, comprising a lamp base (10), a lamp shaft (11), and a light source (12) that can be exchangeably fixed in sockets (13) mounted in the lamp shaft (11). According to the invention, the light source is a light-emitting diode (12) or consists of a plurality of light-emitting diodes, which is/are arranged inside the lamp shaft (11) and which illuminate(s) a luminescent body (26) exchangeably placed onto the end of the lamp shaft.

  • Publication number: 20020041139
    Abstract: A portable lamp with adjustment device to obtain different emitted light cones includes a light source received within a concave reflector. The light source includes at least two separately switchable incandescent filaments operatively connected to a power source, which are arranged within the light source to generate a desired light cone. By way of example, according to the invention, a filament intended to generate a small angled light cone, i.e. for far distance illumination, draws greater power from the power source than a filament intended to generate a wide angled light cone. To this end, each of the filaments has different illuminous efficiencies. An additional laser light source, electronic flash unit controlled by the light source may also be provided.
