摘要: A method for maximizing the performance of a luminaire (1) emitting light is provided, which method comprises determining a target color point (T) corresponding to a predetermined color, providing a first light source (2) emitting light at a fixed reference color point (W), and providing a second light source (4) being able to emit light at an adjustable color point (RGB). Said adjustable color point (RGB) is selected such that a combination of light emitted by the first and the second light sources (2, 4) together produces light at the target color point (T), wherein the adjustable color point (RGB) is selected based on the position of the target color point (T) and the reference color point (W) for maximizing the performance of the luminaire (1).With the provision of a solution in accordance with the present invention, fewer computations need to be performed in order to maximize the illumination performance of the luminaire (1).

摘要: A color cathode ray tube is provided with a saddle-shaped shadow mask.As a result, the sensitivity to doming and microphonics of the mask is improved. This is advantageous, in particular, for a cathode ray tube having a very flat display window. Preferably, the display device in which the cathode ray tube is employed is provided with two dynamic quadrupoles, for example, in front of the electron gun and in front of a deflection unit.

摘要: Disclosed is an LED-based bulb-type lamp, including a cooling structure and a plurality of LEDs thermally connected to the cooling structure. The lamp includes at least three separate LED arrays oriented substantially parallel to its central longitudinal axis, such that the LEDs are interspersed among a plurality of light-transmission sub-areas of the LED-based lamp. One or more portions of the cooling structure of the lamp extend to its outer surface, as assembled, such that light-transmissive and heat-dissipating areas are spread over the outer surface, for example, in an alternating manner.
