    摘要: A headlamp (1) for a bicycle includes an LED element (10), a power supply device (20) supplying electric power to the LED element (10), a vibration sensor (30) detecting vibration, a luminance detector (40) detecting ambient illuminance, and a switching device (50) providing ON-OFF control of electrical connection between the LED element (10) and the power supply device (20) in response to a result detected by the vibration sensor (30) and a result detected by the illuminance detector (40). The vibration sensor (30) has a helical spring and a central metal conductive wire passing through the helical spring, and the helical spring and the conductive wire are disposed to extend in a direction obliquely intersecting with a horizontal direction and a vertical direction when the headlamp is attached.
