A lighting system for a bicycle. A lamp and a beam are mounted to the bicycle. A generator is mounted to the beam such that the beam holds the generator in position to be frictionally driven by contact with a bicycle wheel. The generator provides a three-phase output voltage. A sensor monitors the generator and provides an output signal proportional to the speed of the bicycle. A first sensing circuit receives the output signal from the sensor and provides a first control signal when the output signal exceeds a first predetermined value. The first control signal is operative to change the output voltage from the three-phase output voltage to a single-phase output voltage to prevent damage to the system.

A bicycle lighting device configured to be mounted to a bicycle includes a lamp case, a control case and a mounting unit. The lamp case has a light emitting diode arranged therein. The control case is connected to the lamp case by a hinge. The control case is configured to clamp onto a handlebar. A control circuit for controlling the light emitting diode is installed inside the control case. The mounting unit is for attaching the lamp case and the control case to the handlebar in such a fashion that the lamp case and the control case are drawn close together.

A bicycle lighting apparatus comprises a lighting case structured to be mounted to the bicycle and a lighting element supported by the lighting case. A lighting case mounting unit is disposed on the lighting case and is structured to detachably mount a separate display unit to the lighting case.

Provided is a bicycle lighting device that brightens side portions in which brightened positions in the side portions are not limited as much as possible and light in the side portions and light in a front portion can be distinguished. A headlight 14 includes: an outer case member 20; a lens member 22; an inner case member 24; a light emitting portion 26; a reflective member 28; and a light escaping portion 30. The outer case member is a member that is securable to a bicycle, and includes a housing space 41 formed therein, a first opening 42 placed in a front surface, and a second opening 43 placed in a side surface. The lens member is a translucent member that covers the first opening. The inner case member is a translucent member that is at least partially placed in the housing space of the outer case member and covers the second opening from the inside. The light emitting portion is placed in the inner case member. The reflective member is a member that is placed in the inner case body and reflects light from the light emitting portion toward the lens member. The light escaping portion is able to cause the light emitted from the light emitting portion to escape toward the inner case member.

A bicycle lighting device is configured to make possible the efficient illumination of an LED while controlling power loss between the generator and the LED. An LED unit has at least one LED. A protector circuit controls the flow of current to each LED according to the internal resistance of the generator and the constant voltage properties of the LED unit.

A bicycle lighting fixture includes a housing defining therein an accommodation chamber, a reflector mounted in the accommodation chamber and a light source mounted in the accommodation chamber for emitting light onto the reflector. The reflector provides a curved reflecting surface facing toward the outside of the accommodation chamber and defining a plurality of reflecting surface areas at different elevations and a terrace surface connected between each two adjacent reflecting surface areas.

A bicycle illumination apparatus is provided with a plurality of light sources and a controller. The light sources include at least one light-emitting diode that emits light in accordance with an electrical output of a generator. The controller is configured to selectively control an electrical connection between the power generator and the light sources in accordance with a rotating state of the generator.

The invention involves a new bicycle lighting device. The bicycle used in people daily life has no lighting equipment, a little bicycle is equipped with taillight on the tail, but the light is supplied power relying on the battery or dry battery, the cost is high so it is not easy to be promoted, while the lateral environment is not seen when people rides in night, so dangerous incidents are easy to happen. The invention consists of generator, headlights, taillights and pedal lights, the generator can be installed on the pedal gear or on the edge of fore and rear wheel axle and generates by friction of gear or bicycle wheel rotates; the headlights can include one or more (including main lights and left / right turning lights), the pedal light pedal (the left and right pedal lights are installed separately), the taillights also can include one or more, the headlights, taillights and pedal lights are connected with the generator and are equipped with switch control. The invention is scientific, rational, safe, reliable, low production cost, very wide scope of application, flexible and convenient installation and use, it is easy to be promoted.

Systems and methods for providing adequate lighting and sighting for a bicycle are disclosed. A lighting system that includes an illumination ring configured to be coupled to a wheel is also disclosed. The illumination ring is configured to simultaneously project light forward and to the side of a front wheel and to project light rearward of and to the side of a rear wheel. The illumination ring may be mounted to or integrated with the bicycle wheel. Methods of controlling light sources on the illumination ring are also disclosed.

The invention discloses an intelligent bicycle lighting device with a wind power generation function. The device comprises a front cover and a rear cover which match each other, the inner side of therear cover is divided into a power generation cavity and a sealing cavity through a first sealing partition plate, a plurality of sets of impellers and generators which match each other are arranged in the power generation cavity, and one impeller or two coaxial impellers is or are arranged; a plurality of parallel shaft ventilation nets I matching the impeller is arranged on the front cover; a plurality of parallel shaft ventilation nets II matching the impeller is arranged on the rear cover; vertical shaft ventilation nets matching the impeller are arranged on the left side wall and the right side wall of the rear cover; the impeller comprises a hub and a plurality of blades arranged on the hub. The ends, close to the hub, of the blades are parallel wind force bearing parts, the other ends of the blades are vertical wind force bearing parts, transition parts are arranged between the parallel wind force bearing parts and the vertical wind force bearing parts, the transition parts arein a twisted twist shape, the blades can be blown by parallel wind force and vertical wind force at the same time, and the wind driven generator has the advantages of being ingenious in structure, convenient to use, practical and multifunctional.

The invention discloses a photovoltaic bicycle lighting lamp. The bicycle lighting lamp comprises a photovoltaic module, a DC controller, an LED light source, a battery and a start switch. The photovoltaic module is connected with the battery; The accumulator is connected with the LED light source through a startup switch; The starting switch is arranged on the handlebar of the bicycle; A DC control is respectively connected with that photovoltaic module and the accumulator, the DC control controls the photovoltaic module to charge the accumulator, and the DC controller controls the accumulator to discharge; The battery and the DC controller are fixed on the backlight surface of the photovoltaic module; The DC controller and the photovoltaic module constitute a power supply, and the powersupply is arranged on the handlebar of the bicycle.
