Embodiment Construction

[0044] In the following description, like reference numerals will generally be used to describe like concepts in various embodiments of the invention. Thus, numerals 001, 101, 201 describe light sources according to different embodiments of the invention.

[0045] Unless specified otherwise, technical features described in detail for a given embodiment may be combined with technical features described in the context of other embodiments described by way of non-limiting example.

[0046] figure 1 An electroluminescent light source 001 according to a first embodiment of the invention is shown. figure 1 Explains the basic principles of light sources. The light source 001 comprises a substrate 010 made of silicon on which a series of light emitting diodes or rods in the form of wires 020 protruding from the substrate are arranged. The core 022 of each rod 020 is made of n-type semiconductor material, that is to say semiconductor material doped with electrons, and the outer shel...

Abstract

The invention proposes an electroluminescent light source comprising light emitting diodes arranged on a substrate made of silicon. The light source incorporates electronic circuitry that performs the functions necessary to control the light emitting diodes.

Description

technical field [0001] The invention relates to the field of lighting and light signaling, in particular for motor vehicles. Background technique [0002] In the field of lighting and light signaling for motor vehicles, the use of light sources based on light-emitting semiconductor components (eg light-emitting diodes, LEDs) is becoming more and more common. The LED component emits light when a voltage having a value at least equal to the threshold value (referred to as a direct voltage) is applied to its terminals. [0003] In a known manner, one or more LEDs of a lighting module for a motor vehicle are powered via a power control device comprising a converter circuit. The power control device is configured to convert a current of a first intensity, eg delivered by a current source of the motor vehicle, such as a battery, into a load current of a second intensity different from the first intensity. The control means are typically formed by surface mount components SMD ("S...
