Title (EN) AC LED STRUCTURE WITH OVERLOAD PROTECTION
(FR) STRUCTURE DE DEL CA À PROTECTION CONTRE LES SURCHARGES
(ZH) 具有过载保护的交流发光二极管结构
Abstract: front page image
(EN)An alternating current light emitting diode (AC LED) structure with an overload protection is provided. The AC LED structure (100) includes at least one AC LED (10), a heat dissipation unit (20), and an overload protection unit (30), wherein the AC LED (10) is thermally connected with the heat dissipation unit (20), and the overload protection unit (30) is connected in series between the AC LED (10) and a power supply (40). When an over-current passes through the AC LED structure, the temperature of the overload protection unit (30) will arise due to the over-current until an open-state occurs at last. Therefore, an open-state may occur in the AC LED structure, which prevents the power supply (40) from driving the AC LED, thus the effect of overload protection is achieved.
(FR)L'invention porte sur une structure de diode électroluminescente à courant alternatif (DEL CA) comportant une protection contre les surcharges. La structure de DEL CA (100) comprend au moins une DEL CA (10), une unité de dissipation de chaleur (20) et une unité de protection contre les surcharges (30), la DEL CA (10) étant thermiquement reliée à l'unité de dissipation de chaleur (20), et l'unité de protection contre les surcharges (30) étant connectée en série entre la DEL CA (10) et une alimentation électrique (40). Lorsqu'une surintensité traverse la structure de DEL CA, la température de l'unité de protection contre les surcharges (30) croît en raison de la surintensité jusqu'à ce qu'un état ouvert se produise finalement. En conséquence, un état ouvert peut apparaître dans la structure de DEL CA, ce qui empêche l'alimentation électrique (40) d'attaquer la DEL CA, ainsi l'effet de protection contre les surcharges est obtenu.
