One or more chargeable batteries are received in the housing and coupled to the light device for energizing the light device. An actuating device includes a follower rotatably attached to the housing, and a handle pivotally attached to the follower. A gearing device includes a gear coupled to actuate an electric generating device, to generate electric energy to energize the light device. A weight may be secured to the gear of the gearing device, to increase the moment of inertia of the gear, and to facilitate the rotational movement of the gear relative to the housing.

An illumination device includes a nozzle, a grip, at least one light element connected to the nozzle, and a moveable turbine generator electrically connected to the light-emitting element. The turbine generator includes at least one rotatable blade. When the turbine generator is moved into the nozzle, the impact of a fluid flowing through the nozzle causes the rotatable blade to rotate, thereby generating electric power to power the light-emitting element. When the turbine generator is moved into the grip, the rotatable blade is not subjected to the impact of the fluid flowing through the nozzle, stopping the turbine generator from generating the electric power.

The invention is a system that provides a means to using passing air to turn on an electronically powered device that is removably attached to an exterior portion of a vehicle as the vehicle travels betweens two locations. The invention is also embodied as a device that provides a means to turn on an incandescent light bulb that illuminates an ornament that is attached to an automobile window using passing air caused a moving automobile.

A self-generating type light emitting device for helmet, in which a small generator is operated by wind power generated during driving, the electricity generated by this generator lights light-emitting diodes fitted on the helmet so as to enhance driving safety and impart a decorative effect, is disclosed. The self-generating type light emitting device for a helmet comprises a case 20 having a mounting portion 21, and a protruding portion 22 to provide a predetermined mounting space inside of the case 20; an electricity generating means 30 having a generator 33 fixed by a bracket 34 on the inside of the protruding portion 21 of the case 20, and a rotary blade 31 fixed at the front end of the shaft 32 of the generator 33; and a light-emitting means 40 having a plurality of light-emitting lamps 41 which are lighted by electricity generated from the generator 33.

A wind-powered lamp includes lower and upper covers confining a space and having inlet and outlet holes, a reflective casing disposed in the space to extend outward from the inlet hole in the lower cover, a lamp plate affixed to the reflective casing, a fixing frame, a power generating motor, a rotor and a storage battery. The upper and lower covers respectively have an open end defining inlet and out holes, an inner sidewall extending inwardly from the open end. The motor fixing frame has engaging ribs engaging with slots formed on inner side wall to affix the motor fixing frame. The power generating motor is affixed within the fixing frame such that a motor shaft passes through a shaft hole in the fixing frame to connect with the rotor. The power generating motor, the storage battery and the lamp plate are serially and electrically connected to one another.

The aim of the invention is to provide a device for generating alternating light effects in a simple manner. To achieve this, the device comprises a grip element, a thermal activation unit and at least one light effect current generator with an exit opening, through which a component that produces the light effects can be expelled by means of a stream of carrier gas in a discharge direction. The component that produces the light effects can be activated by the thermal activation device.

The invention provides a mobile lamp trolley with a lighting lamp panel capable of being rotated freely. The lamp trolley comprises a lamp trolley base, a hydraulic control system, an engine, an oil tank and an electric generator allocated on the lamp trolley base, a ratable stand column connected with the hydraulic control system, a hydraulic lifting connecting rod connected with the stand column and a lighting lamp panel connected with the hydraulic lifting connecting rod, and a mobile lamp trolley contact control module, wherein the lamp trolley base is provided with telescopic hydraulic support feet; advancing wheels are arranged at the lower part of the lamp trolley base; the ratable stand column is fixed on a fixed supporting seat and can rotate relative to the fixed supporting seat; the fixed supporting seat is fixed on the lamp trolley base and is provided with multiple ling passing holes at the bottom; the ratable stand column is of a hollow structure; a hydraulic rotary joint assembly, a collector ring assembly and a gas-electric transition cross-under pipe are arranged in the ratable stand column. By applying the mobile lamp trolley disclosed by the invention, the problem that an oil-in pipeline and an electric connecting wire are twined is solved, the rotation angle of the lamp panel can be controlled freely, and the mobile lamp trolley is suitable for all kinds of remote and night use occasions.

The invention discloses a flashlight. The flashlight comprises a cylinder, a handle, a first battery, a second battery, a first charging device, a light emitting device and a circuit board. The handle is rotationally mounted in the cylinder; the first charging device is mounted on the handle, and is used for charging the first battery; the light emitting device is mounted in the cylinder, and is used for providing illumination; the circuit board is mounted in the cylinder, and is used for driving the light emitting device; the first battery is mounted in the cylinder, is electrically connected with the circuit board, and is used for supplying power to the light emitting device; and the second battery is mounted in the cylinder, is electrically connected with the circuit board, and is used for supplying power to the light emitting device.
