Abstract

In the present invention a lighting equipment driving means which make it possible to drive a light emitting means to emit light for a long time with high brightness even when a moving speed of a bicycle is at so low level of speed that a normal human being walks, is provided and in the light emitting means, the driving terminal 4, 4′ of the small sized direct current motor 1 and the input terminals 7, 7′ provided on a substrate plate 6 of the light emitting means 5 with the LED 15 are connected to each other directly via a pair of conduction wires 8, 8′, without interposing any one of a rectifier circuit and an electric energy storage circuit, wherein a rotor axis 2 of the small sized direct current motor 1 is rotated at high rotational speed to generate the electricity whereby said light generating means 5 emits light continuously and uniformly in high luminance condition.

Claims

3. A lighting equipment according to claim 1 or 2, wherein said small sized direct current motor is a small sized direct current generating device which can be configured to output a predetermined electric power.

4. A lighting equipment according to claim 3, wherein said lighting equipment is further provided with a controlling means which can control within a predetermined period, an upper limit of an amount of electric current flowed through said LED provided in said light emitting means caused by an output power generated from said direct current motor or said small sized direct current generating device each having an ability for generating electricity.

5. A lighting equipment according to claim 4, wherein said controlling means is provided with a means in that said upper limit of an amount of electric current flowed to said LED provided in said light emitting means from said small sized direct current motor or said small sized direct current generating device can be controlled, by matching an internal impedance of said small sized direct current motor or said small sized direct current generating device with a load impedance of said LED provided in said light emitting means.

6. A lighting equipment according to claim 4, wherein said controlling means is provided with a driving current controlling means which controls the drive current for said LED, and which comprises only electronic circuit devices without including any of rectifier circuit.

7. A lighting equipment according to claim 6, wherein said driving current controlling means is further provided with a LED selecting means which arbitrarily selects at least one predetermined LED to be emitted among a plurality of LEDs.

8. A lighting equipment according to any one of claims 1, 2 and 4 to 7, wherein said lighting equipment is further provided with a switching means which can selectively select a turning-on condition of said LED provided inside said light emitting means from either one of a continuous turning-on condition or an intermitted turning-on condition.

9. A lighting equipment used for a bicycle which comprising said lighting equipment as defined by any one of claims 1, 2 and 4 to 8.

10. A lighting equipment used for a bicycle according to claim 9, wherein said light emitting means emits light continuously with keeping a level of brightness exceeding a predetermined level of brightness independent of a speed of a bicycle except for a predetermined speed condition of the bicycle.

11. A lighting equipment used for a bicycle according to claim 10, wherein said LED of said light emitting means can be turned oh simultaneously with said bicycle starts to move and further an optical axis of said LED can be freely switched into any one of direction selected from a group comprising an upper direction, a lower direction, a left direction and a right direction.

2. A lighting equipment which comprises a small sized direct current motor having an ability for generating electricity and a light emitting means comprising at least one LED(Light Emitting Diode), wherein said lighting equipment further provided with a rotation transmitting means which rotates a rotor axis of said small sized direct current motor at high rotational speed and further wherein said rotation transmitting means being provided with a kinetic energy transmitting function to transmit the same to said rotor axis with a rotational speed which is lower than a rotational speed of said rotor axis to thereby generate the electricity from said small sized direct current motor with said rotor axis so that said light emitting means emits light continuously and uniformly in high brightness condition.
