Title (EN) TEMPERATURE CONTROLLED LED ARRAY
(FR) RÉSEAU DE DEL À COMMANDE DE TEMPÉRATURE
Abstract: front page image
(EN)A lamp in which a LED array is coupled to a transistor such that the same amount of current flows through both. The voltage level at the control (e.g., base) terminal of the transistor is controlled such that the current magnitude is reduced when the operating temperature rises. As a result, the heat generated from the junctions of the LEDs in the LED arrays is reduced, thereby compensating for the increase in the operating temperature.
(FR)L'invention concerne une lampe dans laquelle un réseau de DEL est couplé à un transistor de sorte que la même quantité de courant circule à travers les deux. Le niveau de tension à la borne de commande (par ex., la base) du transistor est commandé de sorte que l'amplitude du courant est réduite lorsque la température de fonctionnement augmente. Ainsi, la chaleur générée par les jonctions des DEL dans les réseaux de DEL est réduite, ce qui permet de compenser ainsi l'augmentation de la température de fonctionnement.
