Shenzhen Benwei Lighting Technology Co., Ltd. is one of the best manufacturers and suppliers of digimark smart bulb in China. Welcome to buy durable products for sale here and get pricelist from our factory. All customized products are with high quality and competitive price.

In the case of an unplanned power loss or load shedding, the Digimark Emergency LED bulb continues to operate. The emergency bulb can be used in lieu of a normal bulb, and when it is turned on, the built-in battery will begin to recharge. The intelligent light control instantly lowers the brightness of the lamp during a power failure to prolong the battery's life while still providing you with 3 hours of backup lighting.

FAQs

How does the lightbulb distinguish between a light switch being turned on and a power outage?
Internal emergency control IC will measure L and N voltages.
- There are still neutral voltages present when the power of a single line is shut off (a light switch is turned on), preventing the lamp from entering emergency mode.

If there isn't any other demand on the switched circuit, what impact does the light change have?
- The emergency light will only turn on in emergency mode if there is a loop in the external circuit or if the IC cannot identify any voltage in the input cable (power loss). Other parts of the installation's same electrical network contribute to the loop's creation.
- The IC can recognise this situation because the impedance between L and N is very low.

What circumstances allow the light to function in a power outage?
- When there is a loop in the external circuits. - When the IC cannot identify any voltage from the input wire. Other parts of the installation's electrical circuit that are connected to this circuit form the circle. In this case, the IC can recognise that there is very little impedance between L and N.
