Abstract

The invention discloses an emergency lamp control integrated circuit, and the circuit is used for connecting a first light source, a second light source, a driving circuit, a mains supply circuit and a battery. The emergency lamp control integrated circuit detects the output state and the battery state of a commercial power circuit, and automatically recognizes whether one battery is used or two batteries which are combined in series according to the output state and the battery state of the commercial power circuit; when the circuit where the second light source is located is disconnected, an open-circuit protection function is started immediately; a constant current flowing through the first light source is controlled to flow through the second light source so as to enable the second light source to emit light; and a constant current flowing through the first light source is controlled to flow through the battery so as to charge the battery.

Description

technical field [0001] The invention relates to the field of emergency lights, in particular to an emergency light control integrated circuit. Background technique [0002] The existing LED emergency light control integrated circuit can only be applied to one battery or multiple batteries connected in parallel, but not to two batteries combined in series, and the circuit structure is complex, there are many components, the manufacturing process is also complicated, and the reliability is low. And the security is very low, the cost is very high. [0003] Therefore, how to provide an emergency light control circuit capable of connecting batteries in series has become a demand in the prior art. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide an emergency light control integrated circuit, which is not only suitable for one battery, but also suitable for two batteries combined in serie...
