Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] In the embodiment of the present invention, by using a drive circuit including a first switch, a power supply switch module, a pulse signal generation module, and a lighting control module in an LED emergency lighting fixture, it can be used when there is no light or the light is dark in the external environment and the external alternating current cannot supply power normally. The direct current is obtained from the power supply battery to drive the LED load, and at the same time, the circuit structure is simplified, the power consumption of the whole circuit is reduced, and the cost is redu...

Abstract

The invention belongs to the field of LED driving and provides an LED emergency lighting lamp and a driving circuit of the LED emergency lighting lamp. A driving circuit comprising a first switch, a power supply switch module, a pulse signal generating module and a light-emitting control module is adopted by the LED emergency lighting lamp so as to be used for obtaining direct currents from a power supply battery to drive an LED load when light rays do not exist in the external environment or light rays are insufficient and normal power supply cannot be achieved through external alternating currents. Meanwhile, a circuit structure is simplified, power consumption of the whole circuit is reduced, cost is reduced, and therefore the problems that power consumption is large, the circuit structure is complex, and cost is high in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of LED driving, and in particular relates to an LED emergency lighting lamp and a driving circuit thereof. Background technique [0002] At present, as a new type of light source, LED has been widely used in various fields due to its advantages of low energy consumption, high brightness and long life. The same applies to the field of emergency lighting. [0003] Although the LED driving circuit used in the prior art in the emergency lighting can drive the LED, the power consumption of the overall circuit is large, the volume is large and the structure is complicated because it contains high-power devices, which also increases the cost. Therefore, the prior art has the problems of large power consumption, complicated circuit structure and high cost. Contents of the invention [0004] The purpose of the present invention is to provide a driving circuit for LED emergency lighting lamps, aiming at solving the problem...
