Abstract: A process for controlling the brightness (dimming) of a gas-discharge lamp (GE) which is located in a series resonant circuit (L1, C1) connected to a rectifier-inverter combination (10, 20), by varying the frequency (f) and the duty ratio (D, d) of the output alternating variable (uw) generated by the inverter and supplied to the gas-discharge lamp and to the series-resonant circuit (X; L1, C1, GE). The lamp (GE) is operated in a frequency range in which the dependency of the lamp power (Pab) on the frequency (f) of the output alternating variable (uw) can be represented by the duty ratio (D, d) as a parameter as a family of characteristic curves (K1, K2, K3, ...), each of which runs in the manner of a bell-shaped curve starting from a maximum value and reducing to form a point of inversion. The maximum value of the individual characteristic curves (K1, K2, K3, ...) of the family becomes smaller as the duty ratio (d1, d2, d3, ...) associated with these characteristic curves (K1, K2, K3, ...) as a parameter becomes smaller. The process is intended to be designed such that the brightness of a gas-discharge lamp can be varied in a stable manner without flicker. This is achieved in that the frequency (f) and the duty ratio (D, d) are in each case selected such that the operating point (B1, B2, B3, ...), with at least two characteristic curves selected or available for a specific lamp power (Pab), in each case coming to rest on that characteristic curve which has the lower gradient at this lamp power (brightness). <IMAGE>

Date Dec. 4, 1992A method for manufacturing light panels consisting of a plate shaped carrier with light conducting fibers fixed therein according to a given pattern. The method includes the steps of inserting the top end of each fiber from a fiber supply through openings in a mold. The mold is then filled with a castable plastic layer which is allowed to set to form a carrier. The carrier retains the fibers with the top ends of the fibers extending above the carrier. The top ends of the fibers extending above the carrier are melted by heat from a laser to form a melted nob at the top end of each fiber to act as a lense. A cover layer is applied on the carrier to embed the top end of each fiber and to protect the carrier. The carrier can be removed from the mold to allow the mold to be refilled with another castable plastic layer to form a next carrier for repeating the process. Removable plugs may be initially inserted into the openings of the mold to facilitate removal of the carrier at a desired angle. The bottom end of the fibers beneath the carrier may be compressed together into a bundle and cut to form a light intake head.
