Abstract

Light has become the essential part of people. Works can be seldom done in absence of light. The aim of this paper is to design a Standby automatic LED light. It switches on automatically on power shutdown. This device has high luminous value, extensive valuable life and small size. Besides, they consume less power and need no manual intervention. The rechargeable battery is used to power up the LED. The battery charges when the power exists. LDR is used to sense day and night. It helps the LED glow only during night when the power supply fails. The suggested method is not complex and inexpensive. Its core feature is the ease of implementation and reliability. The designed circuit of the Standby automatic LED light is verified and fabricated. The output obtained is satisfactory.
