Title
(EN) A LAMP USING A LIGHT EMITTING DIODE (LED) AS A LIGHT SOURCE
(FR) LAMPE UTILISANT UNE DIODE ELECTROLUMINESCENTE (DEL) COMME SOURCE DE LUMIERE
Abstract
(EN)
This invention relates to a lamp (80) using a light emitting diode (LED) (30) as a light source. The lamp includes a framework (12), and an LED holder (31) mounted on the framework for holding the LED. A primary reflector (34), having a primary reflecting surface (36) for reflecting at least a portion of light emitted by the LED, is mounted on the framework, being located in a path along which light is emitted by the LED. A secondary reflector (26) is also mounted on the framework, being located relative to the primary reflector such that light reflected by the primary reflector is reflected on to the secondary reflector. The secondary reflector has at least a secondary reflecting surface (28) which is shaped to reflect light reflected thereonto in a forward direction of he lamp and for focusing said light into a substantially focused beam. The invention extends to method of focusing light emitted by and LED.
(FR)
La présente invention concerne une lampe (80) utilisant une diode électroluminescente (DEL) (30) comme source de lumière. La lampe comprend un cadre (12) et un support de DEL (31) monté sur le cadre pour soutenir la DEL. Un réflecteur primaire (34), présentant une surface réfléchissante primaire (36) pour réfléchir au moins une partie de la lumière émise par la DEL, est montée sur le cadre et est située sur un trajet le long duquel la lumière est émise par la DEL. Un réflecteur secondaire (26) est également monté sur le cadre et est placé par rapport au réflecteur primaire de manière à ce que la lumière réfléchie par le réflecteur primaire soit réfléchie sur le réflecteur secondaire. Ce dernier présente au moins une surface réfléchissante secondaire (28) qui est façonnée de manière à réfléchir la lumière réfléchie sur celle-ci dans une direction orientée vers l'avant de la lampe et pour focaliser ladite lumière en un faisceau sensiblement focalisé. L'invention concerne en outre un procédé de focalisation de la lumière émise par une DEL.
