Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, 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.

[0022] Such as figure 1 As shown, the voltage indicating circuit provided in this embodiment includes a trigger module 110 and an indicating circuit 120 .

[0023] The trigger module 110 judges whether the input voltage is within the preset range, and if the input voltage is not within the preset range, then output an indication signal, the indication signal includes an undervoltage signal and an overvoltage signal, and the indication circuit 120 according to the undervoltage signal or The overvoltage signal indicates that the voltage is out of range.

[0024] The trigger module 110 includes ...

Abstract

A voltage indicating circuit comprises a triggering module and an indicating circuit. The triggering module is used for judging whether voltage is in a preset range, and outputting indicating signals when the input voltage is not in the preset range, and the indicating signals comprise undervoltage signals and overvoltage signals. The indicating circuit is used for indicating the out-of-scope voltage range according to the undervoltage signals or the overvoltage signals. In the voltage indicating circuit and a lamp with the voltage indicating circuit, whether the input voltage exceeds the preset range can be judged by the triggering module, if the input voltage exceeds the range, the out of scope range can be indicated, and power utilization devices can be prevented from working under the undervoltage or the overvoltage state for a long time.

Description

technical field [0001] The invention relates to an indicating circuit, in particular to a voltage indicating circuit, and also to a lamp. Background technique [0002] Existing lamps cannot remind customers in time when the grid voltage exceeds the rated voltage, which leads to long-term over-power or under-power operation of the lamps and shortens the service life of the lamps. Contents of the invention [0003] Based on this, it is necessary to provide a voltage indicating circuit for indicating that the voltage exceeds the range. [0004] Voltage indicating circuit, including: [0005] The trigger module judges whether the input voltage is within the preset range, and if the input voltage is not within the preset range, then outputs an indication signal, the indication signal includes an undervoltage signal and an overvoltage signal, and the trigger module includes a first resistor, a second Two resistors, a third resistor, a fourth resistor, a fifth resistor, a first...
