  • Patent number: 8246201
    Abstract: The invention relates to a specific printed circuit (7) comprising independent etched blocks (4) or segments in series of four such that, on a series circuit comprising five LEDs, the four blocks serve as the positioning and connection points for the welding of the pins of the LEDs, said pins being welded in an anode-to-cathode series, or the reverse depending on the direction of the current, i.e. eight electrodes in isolated blocks, such as to ensure that the connection is powered and the LEDs are fixed correctly in series of five. According to the invention, the square or rectangular blocks have a large surface (2) such that the successive holes do not tear the film of epoxy copper. In addition, said blocks are disposed along a path and a successive diagram (21) defines the symbol or pattern to be represented by the LEDs (12) which are disposed and aligned on the other decorated face of the epoxy.

  • Patent number: 8035306
    Abstract: The invention concerns a circuit for setting all types of LED'S (7), mounted in series of five, their particular arrangements in series of five, powered by a direct voltage higher than 14 volts, using an LM 317 T regulator (1) and a potentiometer of 4.7 kOhms (8) providing them with a variable luminance. Complementary setting resistors (R1, R2, R3), are arranged in series or in parallel, on the trigger or at the regulator output, so as to obtain a setting stroke starting form the outset of the illumination that is around 7.5 volts, up to its maximum performance around 12.5 volts. The invention is designed to replace all the applications where fixed LED'S are used.
