A fluorescent lamp mainly includes a lamp tube (1), a tube holder (2) and a lamp cap (3), wherein the tube holder (2) has one end fixed to the lamp cap (3) and the other end assembled to the lamp tube (1), characterized in that the walls (2-6) of the tube holder (2) are moved outward in radial direction, thereby substantially circularity gaps (2-3) are formed between the walls (2-6) and the end parts (1-2) of the lamp tube (1), and that the gaps (2-3) are filled with suitable heat insulating material (5) having low heat conduction and resistance to high temperature. An advantage of the lamp is that the hottest parts (2-2) of the tube holder (2) no longer melt and thereby safety is ensured, and that smoke or blackening will not appear any longer. Such fluorescent lamp will enjoy more popularity of the users.
摘要:
A light module has at least one light source mounted on a base, especially an LED, a housing to accommodate the base, an electrical connection element for power supply of at least one light source. An outer line of the connection element is formed by the housing, and an inner line, especially center line, of the connection element, which is at least partially enclosed by the outer line, contacts the base.

A method for controlling the emission behavior of luminaires in an arrangement of a plurality of luminaires is provided. The method may include using a first luminaire of the plurality of luminaires to define the desired emission behavior at least of itself and at least of one further luminaire; emitting light by means of the first luminaire, to which signals are applied that transmit at least one information item relating to the desired emission behavior; and receiving the light by means of at least one second luminaire, reading out the at least one information item, and emitting light in accordance with the at least one information item.
摘要:
An illumination device is specified which includes a radiation source having at least one light-emitting diode, a control unit and a radiation receiving unit. The radiation receiving unit is provided, during operation of the illumination device for receiving both a radiation emitted by the radiation source and a reference radiation and for generating a measurement signal upon receiving the radiation from the radiation source and a reference signal upon receiving the reference radiation. An operating point for the radiation source is tunable by the control unit in a manner dependent on the measurement signal and the reference signal. Furthermore, a method is specified by which an emission characteristic of an illumination device can be adapted to a predetermined emission characteristic in a simplified manner.
摘要:
In a method for projecting an image onto a projection area (10) by at least one first (110) and second (210) beam, in order to create an improved image on the projection area, the deviation of the projection of the first and second beam on the projection area is determined, and the intensity of the first and/or second beam is varied over time according to the previously determined deviations.
摘要:
A lighting device (1) comprising at least one light source (5), at least one base (7) thermally and electrically operationally connected to the light source (5), and at least one bulb fitting (10, 27) provided for receiving the base (7). The base (7) has at least one first heat transfer surface (15) and the bulb fitting (10, 27) has at least one second heat transfer surface (17) in contact with the first heat transfer surface (15) either directly or by way of a foil (16). At least one device (14, 26, 32, 39) is provided for exerting a predefined press force between the first heat transfer surface (15) and the second heat transfer surface (17).
