A torch has a body 1 and a battery 5 housed in the body 1. The body 1 carries an LED 4 and a total internal reflection lens 6 at the end opposite from a press button switch 3. An inertial sensor or accelerometer 7 is mounted in the housing. The LED 4 is powered by the battery 5. Charging contacts 8 are exposed on the housing. A control printed circuit board 2 is mounted in the body 1. The LED 4, the battery 5, the switch 3 and the accelerometer 7 are connected to the PCB 2. The accelerometer 7 detects movement of the lamp in terms of acceleration of the lamp when the lamp is tapped. The lamp switches between different states on detection by the inertial sensor of a tapping action of a first or second type. |
