Problems solved by technology
[0004] However, if the above-mentioned high-power switching power supply is damaged, it will affect the entire LED street lamp power supply system, making all LED street lamps in the entire power supply system unable to work normally. If the backup power supply scheme is adopted, the cost will be relatively huge.

The invention discloses an LED street lamp and its control device. The device includes a switching power supply, the switching power supply includes an input terminal and an output terminal, and the device also includes a street lamp power supply line; the device also includes a first relay, The second relay and the third relay, the first relay is connected to the input end of the switching power supply, the second relay is connected to the output end of the switching power supply, and the third relay is connected to the street lamp power supply line; The device further includes a controller for controlling the on-off of the first relay, the second relay and the third relay, and the controller is respectively connected to the first relay, the second relay and the third relay. The invention can control the output of alternating current or direct current of the switching power supply according to the actual situation, so as to ensure that the LED street lamp system can work normally under any circumstances.
Description
technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED street lamp and a control device thereof. Background technique [0002] The continuous application of light-emitting diode (Light Emitting Diode, LED) street lamps is accompanied by the problem of damage to a large number of LED street lamps. Among them, the number of damaged LED street lamps due to damage to switching power supplies accounts for a considerable proportion, and the impact of alternating current on various components is an important reason that affects the life of switching power supplies. [0003] In order to solve the above problems, in the prior art, a high-power switching power supply is generally used to convert the alternating current into a direct current, and then transmit it to each LED street lamp through the street lamp power supply line, so that the damage of the LED street lamp caused by the damage of the switching power supply can ...
