Abstract
A bicycle safety light is mounted on the spoke of a bicycle wheel for rotation with the wheel. The light includes a light transmitting, refractive housing with an internal light and light operating circuit. The light is driven by a flasher circuit to produce a flickering effect. The flasher circuit itself is initiated by a motion sensor that senses any motion of the bicycle wheel. A time delay sustains operation of the flickering light for a predetermined period between activations of the motion sensor.
Claims9
A self-contained bicycle light mountable on a bicycle wheel and comprising:
- a housing at least partially of a light transmitting material;
- mounting means for mounting the housing on the bicycle wheel;
- an electronically operable light source within the housing and positioned to transmit light through the housing;
- electric battery means within the housing;
- and
- circuit means within the housing electrically joining the light source and the battery means, the circuit means including:
- (a) flasher means actuable to close the circuit means intermittently so as to cause the light source to flash intermittently;
- (b) motion sensor means responsive to motion of the housing in any direction to actuate the flasher means, and
- (c) time delay means for sustaining the operation of the flasher means for a predetermined duration after actuation of the flasher means by the motion sensor means.
A bicycle light mounted on a bicycle wheel having a plurality of spokes, the light comprising:
- a housing having a cavity therein with at least portions of the housing on opposite sides of the cavity being of light transmitting material;
- mounting means for mounting the housing on at least one spoke of the wheel;
- an electric light within the cavity;
- an electric battery within the cavity;
- and
- circuit means within the cavity electrically joining the light and the battery, the circuit means including:
- flasher means actuable to close the circuit intermittently so as to cause the light source to flash intermittently;
- motion sensor means responsive to motion of the housing in any direction to actuate the flasher means;
- and time delay means for sustaining the operation of the flasher means for a predetermined duration after actuation of the flasher means by the motion sensor means.
