Abstract
A toilet lamp includes a battery box, a metal flexible bar, an insulative sleeve and a light source. The battery box includes at least one battery, a driving component, a sensing module, a cap and a lens. The sensing module detects human presence in the toilet lamp's proximity. The cap covers the driving component. The lens is mounted on the cap. The lens is optically coupled to the sensing module. The lens amplifies an optical disturbance occurred in the toilet lamp's proximity. The lens relays the amplified optical disturbance to the sensing module as a reference in detecting the human presence. The sensing module activates the light source upon detecting the human presence within the toilet lamp's proximity. The sensing module deactivates the light source upon detecting the human presence's leaving from the toilet lamp's proximity.
