LIGHT EMITTING MODULE FOR LINEAR LED LAMP OR LUMINAIRE Russian patent published in 2023 - IPC H01L25/75 F21S4/28 F21K9/20 

FIELD: lighting equipment.

SUBSTANCE: light-emitting module for a linear LED lamp or luminaire contains an extended printed circuit board (P) 1 with a rectangular sweep of width h and length with at least one LED (C) 2 installed on it and two pairs of pin terminals (K) 3, 4 and 5, 6 for connecting power, placed on its opposite ends whose axes of symmetry are parallel and lie in the same plane perpendicular to the plane of symmetry P 1 along its length P 1 is made with a sweep width h = 10…120 mm and a length of laminate with a metal base, having a thermal conductivity coefficient of at least 110 W/(m K) and a thickness of at least 0.3 mm, with a metallization layer thickness of at least 0.017 mm, having a resistivity of no more than 1.8×10^-8 ohm m, and an insulating layer thickness of no more than 0.1 mm with a thermal conductivity coefficient of at least 0.25 W/(m K). P 1 is divided into three zones along the width of h. C 2 is installed in the central part of the middle zone having a width of z= (0.3…0.5)h. The extreme zones of equal width s = (0.25…0.35)h are bent relative to the surface plane of the middle zone in the direction of the optical axis C 2 to an angle of 5…60 degrees. At least the surfaces of the extreme zones of P 1 on the side of the installation C2 are made with a reflective coating. The calculated operating direct current C 2 is set within 0.4…0.92 of the nominal passport direct current I_F, and the calculated maximum direct voltage on the LED is limited to 0.96…0.99 of the nominal passport direct voltage V_F. Pairs K 3, 4 and 5, 6 are installed in the middle zone. K 3, 4 and 5, 6 are placed symmetrically relative to the plane of symmetry P 1 along its length and the axes of symmetry of the pairs are spaced by a distance in millimeters y = 5α±0.25 mm, where α∈{1; 2.6}. At least in a pair, one K 3 or 4 and 5 or 6 has an electrical connection with the corresponding terminal C 2. The diameter of K 3-6 is 1.5…2.5 mm, and the length of the protruding part of K 3-6 relative to the corresponding end P 1 is at least 10 mm.

EFFECT: invention expands the scope of the module by increasing the light output, adjusting the protective angle, as well as increasing the rigidity and improving the manufacturability of the design.
