Abstract: An undervoltage protection circuit for LED lamp includes a DC/DC converter, and a controlling circuit module. The controlling circuit module includes a signal collecting unit configured for collecting a signal, a signal comparing unit electrically connected to the signal collecting unit, and a signal processing unit electrically connected to the signal comparing unit.

The signal processing unit is configured for processing the signal output of the signal collecting unit to turn on or turn off the DC/DC converter. Whenever the voltage input is less than the threshold voltage which indicates an undervoltage condition, the controlling circuit module produces a high level and causes the DC/DC converter to not work as a result. Inversely, the controlling circuit module drops to a low level and the DC/DC converter begins to work.

Abstract: A lens includes an optical axis, a light source recess arranged through the optical axis, a reflection surface crossing through the optical axis, and a critical reflection surface which is arranged in a spaced relationship with the optical axis. The critical reflection surface is arranged between the light source recess and the reflection surface and receives the light from the light source recess and the reflection surface and reflects the light from the light source recess and the reflection surface towards the reflection surface.
