摘要:
A light emitting device is mountable to a vehicle which has a rotary part and a non-rotary part, and includes a light emitting part (60) which is installed to one of the rotary part such as a wheel and the non-rotary part such as a fork, and an LED (51) which is installed to the other of the rotary part and the non-rotary part. The LED (51) is set so that a range of at least 1.2 times the width of the light emitting part (60) becomes an irradiation area.
摘要:
An electrical power generation device for bicycles is disclosed. Said electrical power generation device comprises one or more magnetic elements (4) to be propellably attached to a bicycle and an energy conversion unit (1) to be fixedly attached to the bicycle, where the energy conversion unit (1) includes a piezoelectric transducer (2) operatively connected to a ferromagnetic piece (3), the one or more magnetic elements (4) being arranged to be moveable past the ferromagnetic piece (3) such that a magnetic force is exertable on the ferromagnetic piece (3), the ferromagnetic piece (3) being deflectable when the one or more magnetic elements (4) are located in close proximity of the ferromagnetic piece (3). The mechanical stress/strain imposed on the piezoelectric transducer (2) when it is bent due to the deflection of the ferromagnetic piece (3) generates a voltage (V) across the terminals of the piezoelectric transducer (2), which is subsequently converted into usable electrical power.

A small vehicle includes: a vehicle body frame (1); a front wheel (2f) and a rear wheel (2r) suspended on a front part and a rear part, respectively, of the vehicle body frame (1); a handle column (28) mounted on the front part of the vehicle body frame (1); a steering handle (3) which is steerably supported by the handle column (28) and capable of turning the front wheel (2f); a step floor (15) formed behind the handle column (28) and on the vehicle body frame (1); and a driver's seat (6) supported by the vehicle frame (1) in the rear part of step floor (15). Lower reflectors (101) or light emitters arranged longitudinally are provided in a portion of a side surface of the vehicle (V), which is close to the ground, for example, side surfaces of the front wheel (2f) and the rear wheel (2r). Thus, there is provided a small vehicle of high visibility having the position of the vehicle correctly recognized by a driver of another vehicle traveling on a driveway, when the small vehicle travels on a pedestrian crossing at night.

A lighting structure of an alarm lamp used to a wheel; the lighting structure having a body (1) and a light guide element (2); one end of the body (1) being installed with the light guide element (2); a light emitting element (3) being installed in the light guide element (2); a first pin(31) of light emitting element(3) being inserted into the body (1); and a battery (13) being installed in the light guide element (2); an upper end of the battery (13) being spaced to the first pin(31); an upper spring (12) being installed between the upper end of the battery (13) and an upper end of the body (1); one end of the body (1) has a lower cover (15); a conductive sheet(14) is installed between the lower cover and a lower end of the battery; a lower spring (141) being in contact to the battery (2); and a negative electrode of the battery being electrically connected to a second pin(33) of the light emitting element (3).
摘要:
A bicycle pedal is provided with a power source, such as a replaceable long-life battery or a rechargeable battery, recharged, from an external power supply via terminals on the pedal, or, if required, by a solar panel on the cycle, and an electronic circuit for driving a number of light emitting devices (LEDs) positioned to provide rearward facing constant or flashing red light to warn approaching vehicles. The circuit is coupled to switch means, such as a force sensitive switch, so that the illumination is enabled when a cyclist puts pressure on the pedal. The safety pedal may also be provided with a light sensitive switch that acts as a poower saving arrangement ensuring operation of the electronic circuit only when the ambient light level is sufficiently low to require rearward illumination. The pedal may also provide a green, white, or some other non-red light forward facing from the pedal.
摘要:
An indication device capable of indicating its location, when used, by securely lighting or flashing a light emitter and securely stopping the wasteful consumption of power, when not in use, by automatically turning off the light emitter, comprising a case body which can be installed, when used, on a moving part using a pressure sensitive adhesive double coated tape or a mounting device, the light emitter which lights up or flashes by a current from the power supply installed on the case body, and an automatic switch which is installed between the light emitter and the power supply and turned on automatically when the device is used.
