LAMP REFLECTOR Russian patent published in 2009 - IPC F21V7/10 

FIELD: illumination.

SUBSTANCE: invention refers to light engineering and can be used for manufacturing reflected lamps in various shapes. The lamp reflector is made of solid blank by in-parallel slitting-and-shearing bending process and consists of a neck, operating profile and meridian rib system. The perimeter of each rib in any section of the reflector is L=2π*(R_r+l-R_o)/N, where L is rib perimeter in any reference section, perpendicular to a tangent in reference profile point; R_r is a neck radius; l is operating profile length in segment of the reflector from the neck to reference profile point; R_o is reflector radius in reference section, perpendicular to reflector symmetry axis and passing through reference profile point; N is number of established meridian ribs. Ribs are designed as two-fold material with discharge holes and grooves so that slitting-and-shearing bending does not break material and reflecting surface integrity. Structural and working holes are formed in flat bar; structural material is cold-worked material pre-coated with reflector.

EFFECT: lower process materials consumption and labour input, for higher ecological safety and performance power efficiency.
