Abstract
A misuse warning module, including a detection circuit and a warning circuit is provided. The detection circuit is electrically connected to the power circuit of the LED lamp to detect the type of external power supply signal and the current level in the power loop and output the detection signal. The warning circuit is configured to generate a misuse warning based on the detection signal to prompt the user that the LED lamp is connected to an incompatible external power supply.
Claims18
A misuse warning module, comprising:
- a detection circuit, electrically connected to a power loop of a LED lamp, and configured to detect a type of an external power supply signal and current level of the power loop to generate a detection signal;
- and
- a warning circuit, configured to receive the detection signal and generate a warning when the LED lamp is not properly installed.
An LED lamp, comprising:
- at least two pins, a first pin and a second pin, configured to receive an external driving signal;
- a power supply module, electrically connected to the first pin and the second pin, and configured to execute power conversion of the external driving signal to generate a driving signal;
- an LED module, configured to receive the driving signal to light up;
- an installation detection module, configured to detect current in a power loop and determine whether to limit the current of the power loop based on the current level of the power loop;
- an impedance adjusting module, electrically connected to the first pin and the second pin, and configured to adjust impedance of the power loop to affect the determination of the installation detection module, wherein when a first resistor is connected in series in the power loop, the installation detection module limits the current of the power loop and the LED lamp cannot be lit normally;
- and when at least two or more of the LED lamps are connected in parallel, the installation detection module does not limit the current of the power loop and the plurality of the LED lights are lit normally;
- and
- wherein, the external power supply signal is supplied to the LED lamp through the power loop, and the first resistor is connected in series with the plurality of LED lamps.
