Embodiment Construction

[0096] image 3 A schematic top view of a first module 100 representing diodes in a first embodiment of the invention.

[0097] Form a 200mm long and 7mm wide linear strip on the PCB 20, implant the following components:

[0098] - on a row, twelve diodes numbered from 1 to 12 from one end of the strip to the other and spaced from each other by approximately 12 mm;

[0099] - Linear regulators sold by National Semiconductor under sample LM317 (ref Figure 4 );

[0100] - Calibration resistors (not shown) associated with the regulators, allowing a current of 800mA to be delivered in each branch, the DC voltage of the power supply being fixed at 12V.

[0101] The diode emits white light with an average flux of 6 lumens, for example. Choose, for example, a diode from the manufacturer Nichia, sold under sample NSSW088A.

[0102] The module thus conceived has an average luminous efficacy of 57 lm / W (average flux = 45 lm; average power consumed = 0.79 W).

Abstract

The invention relates to a module comprising light-emitting diodes (100) and including a printed circuit card (20) bearing diodes (1 to 12) connected in a series / parallel electrical circuit comprising multiple circuit branches (B1 to B4) powered by a common electricity supply (V), each branch comprising two peripheral diodes and, optionally, at least one internal diode. At least one of the multi-diode branches comprises at least one internal reference diode, the two diodes closest to the reference diode belonging to branches other than the multi-diode branch. And / or at least one of the dual-diode branches comprises two peripheral reference diodes and the closest diode on the printed circuit card is a diode belonging to a branch other than the dual-diode branch. The invention also relates to illuminated glazing including such a module.

Description

technical field [0001] The invention relates to an electroluminescent diode module, in particular comprising a printed circuit board carrying a plurality of electroluminescent diodes, and a luminescent glazing comprising such a diode module. [0002] The electroluminescent diodes are small optoelectronic components which, under the action of an electric current, emit light radiation which can range from near UV to near IR. [0003] The electroluminescent diodes (“DEL” in French or “LED” in English) are increasingly being incorporated into glazing. Background technique [0004] It is known to arrange electroluminescent diodes in rows and columns on a printed circuit board (PCB is an abbreviation for "printed circuit board" in English). The module 101 thus formed, often referred to as a "barrette", comprises, for example, on a board 20 a row of six diodes numbered 1 to 6 from one end of the board to the other, as shown in FIG. out. The diodes are "polarized" components, mea...
