An illuminating device and a method for optimizing the light pattern are provided. The illuminating device includes a lamp case having a lighting space; a light-reflecting cup, located in the lighting space and including a light incident side, a light emergent side; a light source, located in the lighting space and corresponding to the light incident side of the light reflecting cup; and a cylindrical lens, located in the lighting space and corresponds to the light emergent side of the light reflecting cup; wherein one surface of the cylindrical lens has a plurality of convex columns extending up and down, and each convex column faces to the light emergent side; wherein, when the light source emits light, the main bright area of the light pattern reflected by the light emergent side of the light reflecting cup is wide at the top and narrow at the bottom.

The present invention provides various aspects of a novel safety light that can be attached to a bicyclist or around the body of an athlete so as to define a well lit, safe distance to avoid collision by a motorist. The present safety concerns would find advantage in an easy to attach safety light that is much larger, more conspicuous and one that provides greater lumens. It would be desirable for athletes and the sports industry if there was provided an improved safety light system to provide a significant warning to let motorists know the safe distance that any motorist and/or his vehicle needs to avoid so as not to hit the cyclist or athlete.

The present invention relates to a multifunctional lighting apparatus for a bicycle, which includes: a lighting apparatus ascending/descending support unit detachably mounted on a steering unit of a bicycle; an ascending/descending movement body part vertically movably located in the lighting apparatus ascending/descending support unit; and a main lighting lamp unit located in the ascending/descending movement body part and irradiating light, and as a result, a lighting lamp unit can be located at a position desired by a driver by adjusting a height of the lighting lamp unit, thereby enhancing both satisfaction and safety in use.

A vehicle lamp provided in a vehicle that travels at a corner by tilting a vehicle body includes: a light source unit; a sensor configured to detect information on outside of the vehicle; and a housing that houses the light source unit and the sensor. The vehicle lamp is disposed at a central portion of the vehicle body in a left-right direction, and wherein the sensor is disposed in the housing at a central portion in the left-right direction.

A bicycle including a handlebar attached to a frame at substantially a midpoint and a seat post, a plurality of light sources normally disposed to project light in either of a first, second or third forward direction, said plurality of light sources controlled by a microcomputer which employs a sensor to monitor the immediate position of either the handlebar with respect to the frame or the orientation of the bicycle with respect to the horizontal, and which selects the appropriate light source to be illuminated to project light in the most preferred direction to illuminate the anticipated path of the bicycle to improve visibility and safety during operation, particularly under low ambient light conditions, and wherein the microcomputer activates one or more front or rear turn signals, and brake lights in response to movement of the bicycle, handlebars or a manual signal.

A display device for a bicycle, e.g., a Pedelec, and/or a bicycle element, and a method of operating a bicycle with a display device are disclosed. The display device includes a carrier for mounting on a handlebar of the bicycle or for mounting on a bicycle helmet. On the carrier, a plurality of controllable luminous elements are arranged.

An adaptive illuminating headlight is provided. The adaptive illuminating headlight includes a stator structure, a rotor structure, a driver, a light emitting unit, an optical assembly, and a control unit, and is installed on a vehicle for use. The rotor structure is configured to rotate relative to the stator structure and has a carrying surface. The driver is arranged between the stator structure and the rotor structure to drive the rotor structure. The light emitting unit is arranged on the carrying surface to emit an illumination light beam. The optical assembly is configured to allow the illumination light beam to project outwardly so as to produce an illumination pattern. The control unit is configured to control the driver to operate according to a posture change of a vehicle body, such that the light emitting unit is driven by the rotor structure to rotate through a predetermined angle.

A lighting system includes a lighting device arranged to attach to a vehicle. The lighting device includes at least two ultraviolet lights and at least one sensor. The sensor determines whether any of at least two areas or zones adjacent to the lighting device are poorly visibly illuminated and/or occupied by personnel, and illuminates these areas or zones with ultraviolet light. The lighting system is configured to operate in conjunction with existing emergency visible lighting and/or flashing visible light systems by using the sensors to sense visible illumination of each individual area or zone provided by the existing emergency visible lighting and flashing visible light systems. The lighting system may be configured to synchronize the illumination of each individual area or zone in ultraviolet light with intermittent absence of visible light illumination in each area or zone from the existing emergency visible lighting and flashing visible light systems.

A motorcycle (1) includes a tail lamp (41), a rear covering (32), rear end components which are a license plate (44) and a license lamp (46), a rear stay (33), and a sensor (60). The tail lamp (41) emits light toward the rear side. The rear covering (32) is provided with the tail lamp (41). The rear end components are disposed more rearward than the rear covering (32). The rear stay (33) extends at least rearward from a connecting portion connected to the rear covering (32), and supports the rear end components. The sensor (60) for sensing an object rearward is at least partially received in an internal space (111) that is formed either in the rear covering (32) or in the rear stay (33).

According to an embodiment of the present disclosure, a portable lighting device capable of adaptive brightness control includes: a light irradiation unit that irradiates light; a brightness sensing unit that measures the brightness of a region in front of a current position at a predetermined distance; and a control unit that controls the amount of light to be irradiated by the light irradiation unit depending on the brightness measured by the brightness sensing unit. Herein, the control unit controls the amount of light by changing the width of an ON pulse period in which the light irradiation unit is operated within a discrete signal controlling the light irradiation unit or by changing the intensity of light in response to a continuous signal controlling the light irradiation unit.
