| 313315000 | INCANDESCENT LAMPS | 12 |
| 20090066213 | Headlight Lamp - A headlight lamp with at least one incandescent filament, which is surrounded by a lamp vessel. The at least one incandescent filament is constructed in such a way that during lamp operation it generates a luminous flux, the value of which is greater than a predetermined permissible maximum value for the luminous flux of the lamp. The lamp vessel has a region of reduced transparency, with the aid of which the luminous flux emerging from the headlight lamp during lamp operation is reduced to a value of less than or equal to the predetermined permissible maximum value. | 03-12-2009 |
| 20100001627 | Incandescent Bulb and Method for the Production Thereof - An incandescent lamp including a lamp vessel with a pinch seal at one end, at least one incandescent filament being accommodated in the interior of said lamp vessel, the incandescent filament being fixed in position in the lamp vessel by at least one electrically insulating holding element provided with filament holders wherein the holding elements are held in the lamp vessel by sections of said lamp vessel being subjected to hot shaping. | 01-07-2010 |

| 20100187969 | LUMINOUS BODY FOR AN INCANDESCENT LAMP AND METHOD FOR ITS PRODUCTION - Luminous body for an incandescent lamp and method for producing such a luminous body. A wire for a luminous body is used whose diameter increases from the outside in. The production method is based either on a deposition method or a metal-removal method. | 07-29-2010 |
| 20110031868 | SYSTEM FOR PROVIDING THERMAL ENERGY RADIATION DETECTABLE BY A THERMAL IMAGING UNIT - In accordance with an aspect of the invention, there is provided a thermal radiation marker ( | 02-10-2011 |
| 20140191651 | METHODS FOR PRODUCING AN ELECTRICALLY CONDUCTIVE MATERIAL, ELECTRICALLY CONDUCTIVE MATERIAL AND EMITTER CONTAINING ELECTRICALLY CONDUCTIVE MATERIAL - A method for manufacturing an electrically conductive material includes steps of: (a) providing a carbon fiber; (b) providing a plastic fiber that differs from the carbon fiber; (c) producing a mixture in the form of a two-dimensional mat from the carbon fiber and the plastic fiber; (d) drying the mixture, optionally; (e) consolidating the mixture; (f) cutting the mixture to size, optionally; (g) carbonizing the mixture, wherein the carbonized plastic fibers form a carbon-based matrix possessing electrical conductivity that at least partially surrounds the carbon fibers. Electrically conductive materials obtained by the method have an increased electrical resistance. An emitter is specified that contains a transparent or translucent housing and an electrically conductive material as to above. These now allow emitters of virtually any length to be operated at customary line voltages. | 07-10-2014 |

| 20090121607 | FILAMENT LAMP AND LIGHT IRRADIATION TYPE HEAT TREATMENT DEVICE - A filament lamp and light irradiation type heat treatment device capable of uniformly thermally processing the entirety of an article to be treated has a filament lamp ( | 05-14-2009 |
| 20090243461 | FILAMENT LAMP - To provide a filament lamp having a plurality of filaments disposed together in sequence in the tube axis direction of a light-emitting tube, with miniaturized hermetically sealed parts, by certain sheets of metal foil ( | 10-01-2009 |
| 20100039017 | TWO-FILAMENT LAMP - Disclosed is a lamp, particularly for a vehicle headlight, comprising two spiral-wound filaments which are retained by three feeders within a bulb that is inserted into a base. The feeders are arranged on top of one another when the lamp is adequately oriented. A tail of the first spiral-wound filament is connected to a dimming cap, said tail being located at a distance from the base, while a tail of the second spiral-wound filament is connected to the central feeder, said tail being close to the base. The second filament tail that faces away and is located at a distance from the base is connected to the upper feeder. According to the invention, the lower feeder is connected to the dimming cap by means of an end, some sections of which are angled away from a longitudinal axis of the lamp. | 02-18-2010 |
| 20100072876 | FILAMENT LAMP - A filament lamp having a filament and an internal lead in which the filament is insulated from contact with the internal lead and prevent from moving during operation to maintain a uniform distribution of light. To this end, the filament lamp includes a luminous tube having an inner wall, and opposing ends on which sealing parts are formed. Multiple filaments are sequentially disposed inside the tube in an axial direction, and internal leads are connected to each filament. An insulating wall is provided along the inner wall of the luminous tube in the axial direction and is disposed around at least one of the multiple filaments. Internal leads running partly parallel to the filaments are positioned between the luminous tube and insulating wall and do not engage the ring supporters of the multiple filaments, which could cause the filaments to move and distribute light in a nonuniform pattern. | 03-25-2010 |
| 20100079052 | FILAMENT LAMP - To provide the structure of a filament lamp having a plurality of independent power supply pathways, the structure being capable of preventing the power supply pathways from electrically shorting to each other, a filament lamp formed of a straight-tube shaped luminous part having multiple filaments (F | 04-01-2010 |
| 20100327731 | LAMP WITH IR SUPPRESSING COMPOSITE - A lamp includes a filament for emitting light. The filament includes an emissive substrate which emits radiation when an electric current is applied. The substrate includes a doped surface and a coating layer supported on the doped surface. The coating layer includes at least one of a carbonitride and a boride. | 12-30-2010 |
