Title (EN) ILLUMINATING APPARATUS WITH LARGE VIEW ANGLE
(FR) APPAREIL D’ÉCLAIRAGE À GRAND ANGLE D'ÉCLAIRAGE
Abstract:
(EN) An LED lamp (100) where the combination of an enlarged globe (106) having a side cross section that is greater than 180°, LEDs (112) with large view angles and the placement of the LEDs (112) at the periphery of the printed circuit board (108) adjacent the globe (106) generates a view angle for the LED lamp greater than 180°. Further, a method of illumination through an LED lamp involving supplying electrical power to a plurality of LEDs (112) through a lamp base (102), generating light through plurality of LEDs (112), where the LEDs (112) have a view angle of greater than 120 degrees and are mounted in a circle at a peripheral edge of a printed circuit board (108), dissipating heat generated by the LEDs (112) through a heat sink (110) coupled to the printed circuit board (108), and transmitting light from the LEDs (112) through a globe (106), the globe (106) having a substantially spherical wall extending greater than 90 degrees from its vertical centerline.
(FR) L'invention concerne une lampe à DEL (100) dans laquelle la combinaison d'un globe agrandi (106) ayant une section transversale qui dépasse 180°, de diodes électroluminescentes (DEL) (112) ayant de grands angles d'éclairage et du placement des DEL (112) à la périphérie d'une carte de circuit imprimé (108) adjacente au globe (106) génère un angle d'éclairage supérieur à 180° pour la lampe à DEL. En outre, un procédé d'éclairage au moyen d'une lampe à DEL est décrit, qui consiste à fournir de l'énergie électrique à une pluralité de DEL (112) par l'intermédiaire d'un culot de lampe (102), à générer de la lumière au moyen de la pluralité de DEL (112), les DEL (112) ayant un angle d'éclairage supérieur à 120 degrés et étant montées en cercle au niveau d'un bord périphérique d'une carte de circuit imprimé (108), à dissiper de la chaleur générée par les DEL (112) par l'intermédiaire d'un dissipateur thermique (110) couplé à la carte de circuit imprimé (108), et à transmettre la lumière provenant des DEL (112) à travers un globe (106), le globe (106) comportant une paroi sensiblement sphérique s'étendant sur plus de 90 degrés à partir de son axe central vertical.
