<p>A bicycle lamp has a body 100 with a printed circuit board 102 and a battery 104 in the body. An LED 105 is mounted on an emitter plate 101 and a reflector 106 is housed on the body at an opposite end to a charging port 103. Adjacent to the port 103 are an array of three illumination status blue LEDS 108 and an array of five battery status red LEDs 109. Components 103 to 109 are connected to a power management circuit 110 that includes an integrated circuit mounted on the PCB 102. The PCB 102 further includes a capacitive Micro-Electro-Mechanical Systems MEMS) inertial accelerometer (123, Fig. 5).</p> |
