摘要： A cold cathode fluorescent tube reflector comprises an extruded ABS thermoplastic support subtending an arc of about 317 degrees and dimensioned to snap fit to the tubular body of fluorescent glass tube. The support has bonded thereto a metallized Mylar film which comprises vapor deposited aluminum which forms a specular second surface mirror. The aluminum coating is next to the support and protected from the ambient atmosphere by the clear Mylar film. The reflector is preferably for 7/8 inch diameter tubes and has a film thickness of about 0.8 mils. In one embodiment, the metallized film is attached during extruding of the support. In the alternative, the film is secured to the support during injection molding of the support.

摘要： Dome-shaped reflector in indoor luminaire having a high intensity lamp and mounted at relatively low height has the lower portion of its reflecting surface formed to reflect light downwardly at an angle of not more than about 50% of the cut-off angle formed by the rim of the reflector relative to the lamp, so as to provide low glare at viewing angles of about 65.degree.-85.degree. from nadir. The cut-off angle is not more than 65.degree..

摘要： The reflector has an outer reflector element (1), e.g. a concave reflector ring, defining the light output opening, a number of light conductors (4) extending perpendicular to the outer reflector element and at least one inner reflector element (2), contained within the light output opening. The inner reflector element is single-walled and may be provided by an endless band formed into a ring, positioned at the centre point of the reflector, with the light conductors provided as spokes extending between the inner and outer reflector elements.

摘要： The ceiling lamp includes a reflector without a raster and composed from profile sections (31,32). The reflector has a involute section in the cross section near the bulb. The involute section ends in downward direction to the light outlet to the internal edge and in upward direction to the vertex of the reflector. A concave reflector section (32) follows the vertex in direction of the outer edge of the light outlet. Preferably, the profile sections of the reflector are blended continuously in form of an involute curve.

摘要： The present invention relates to a process for the production of the profile of reflective elements of a light as well as the lights obtained by this process, the light comprising at least two cylindrical reflective elements (5, 5'). This process is characterized in that it comprises the steps consisting of: defining the position of one end (Ro) of the profile of each reflective element (5, 5') defining an illumination function E( theta ) corresponding to a desired illumination curve, connected to a luminance function L( theta ) by the formula: E( theta )=L( theta )xcos2 theta =k[sxcos theta + rho rxsin ( phi - theta )- rho rosin ( phi o- theta )] cos2 theta if said end (Ro) of the profile of the reflective element (5, 5') is the downstream end of this latter, and an illumination function: E( theta )=L( theta )xcos2 theta =k[sxcos theta - rho rxsin ( phi - theta )+ rho roxsin ( phi o- theta )] cos2 theta if said end (Ro) is the upstream end of said profile determining, from said end (Ro), the coordinates of each of the points (R) of said profile of each reflective element (5, 5') satisfying the differential equation: d alpha /d theta =sin alpha xcos alpha [d log p( theta )/d theta ]-sin2 alpha , in which the function p( theta ) is equal to rho rxsin( phi - theta ) and the value of the angle alpha is equal to ( phi - theta )/r.
