Problems solved by technology
[0002] For battery-powered portable lighting products, when most of the power is exhausted, the lighting effect will drop sharply in a short period of time. Ordinary users often fail to detect the power drop in time and replace or recharge the battery in time, which affects the use of users.
What's more, if there is no low battery warning circuit, the battery may be over-discharged, and over-discharge is irreversible for most batteries.

Embodiment Construction
[0014] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0015] see figure 1 , the low battery prompt circuit for lighting fixtures of the present invention is connected between the battery and the lighting fixtures, and includes: a detection unit 1 , a control unit 2 and a switch 3 .
[0016] The detection unit 1 is used to detect whether the voltage of the battery is lower than a set value, and the switch 3 is controlled by the control unit 2 . The detection unit 1 includes an input terminal and an output terminal, and the input terminal of the detection unit is connected to a battery. The control unit 2 includes an input terminal and an output terminal, and the input terminal of the control unit 2 is connected to the output terminal of the detection unit. The switch 3 includes a control terminal, an input terminal...

The present invention proposes a low-battery prompt circuit for a lighting fixture, which is connected between the battery and the lighting fixture, and includes: a detection unit, which is used to detect whether the voltage of the battery is lower than a set value, which includes an input terminal and The output terminal, the input terminal of the detection unit is connected to the battery; the control unit includes an input terminal and an output terminal, the input terminal of the control unit is connected to the output terminal of the detection unit; the switch is controlled by the control unit, and the control terminal of the switch is connected to the control unit The output terminal of the switch is connected to the output terminal of the detection unit, and the output terminal of the switch is connected to the lighting fixture; wherein, when the detection unit detects that the voltage of the battery is lower than the set value, the control unit controls the switch to open at the set frequency , off, causing the lights to flash to alert the user that the battery is low. The invention also provides a lamp. The invention can wake up the user that the battery power is low, can protect the battery, prevent the battery from being over-discharged, and prolong the battery life.
Description
technical field [0001] The invention relates to a prompting circuit, in particular to a low-battery prompting circuit for lighting lamps and lamps. Background technique [0002] For battery-powered portable lighting products, when most of the power is exhausted, the lighting effect will drop sharply in a short period of time. Ordinary users often fail to detect the power drop in time and replace or recharge the battery in time, which affects the use of users. . More seriously, if there is no low battery warning circuit, the battery may be over-discharged, and over-discharge is irreversible for most batteries. Therefore, it is very necessary to remind the low battery of the lamp. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art, and propose a low-battery warning circuit and a lamp for a lighting fixture, which can give a reminder when the power of the lamp is low...
