Abstract

A bicycle light has in one embodiment a mounting base to connect to the bicycle, and an LED light unit for insertion into and removal from the base. The light unit includes a printed circuit board with LED driver and a rechargeable battery, all of which are encapsulated by a direct overmolding that forms a casing for the unit. For charging the light unit is pulled out from the base and plugged into a USB port via an extending USB blade. A motion detector on the PCB shuts off the LED if no motion is detected for several minutes, thus eliminating need for any exterior switch. Another embodiment is without the USB blade, with the battery charged by inductive charging.

Dependent claims

A light projecting device, comprising:

an LED light unit, the light unit including an LED, a printed circuit board with electronics including an LED driver driving the LED, and a rechargeable battery connected to the printed circuit board,
the LED light unit comprising the printed circuit board, battery and LED encapsulated in a low-pressure overmolding, through the length of the LED light unit, with molding material in direct contact with and encapsulating the circuit board, battery and at least part of the LED to form an integral casing, which is a sole casing of the LED light unit, whereby the LED light unit is completely waterproof,
a switch for connecting the LED to power from the battery, the switch being wholly internal and activated by an internal switching device comprising one of:
a motion sensor, a proximity sensor, a gesture sensor, a moisture sensor, an RF sensor, a magnetic field sensor, and an internal switching device responsive to external force on a prescribed part of the overmolding, and
means for recharging the battery.
