A phototherapy device suitable for shining light on a vehicle driver (3) in order to suppress melatonin production and increase wakefulness, having at least one light fixture (1) located in the region of the head of the driver (3), is improved in terms of its freedom front glare, with undiminished effectiveness, in that the light fixture (1) is embodied to emit essentially nondirectional diffuse light (7) and is located outside the field of view of the driver (3), or at least in the peripheral region of his field of view.

Light generated at a specific wavelength corresponding to a particular color or color range that is distracting or disruptive to a driver during a normal operation is blocked through an inexpensive construction without blocking light in a required range of wavelengths. A projector is constructed such that a plurality of LEDs are arranged in an array configuration. The LEDs can include a tinge of red reduction LED and near-infrared LEDs. The projector can be installed in a vehicle and disposed in proximity to the camera. In some embodiments, the projector can be controlled by a control circuit to be turned on in conjunction with the shutter of a camera.

A visual ability improvement supporting device includes a noise outputting device and a noise generating device. The noise generating device generates noise with intensity which is optimum to a threshold intensity of visibility. The optimum intensity is optimum to induce stochastic resonance (SR). The noise outputting device includes a room lighting device, which illuminates a surrounding area when a lighting switch is turned on, and outputs the visual noise according to the generated noise even when the lighting switch is turned off not to illuminate the surrounding area.

A vehicle lamp is provided herein. The vehicle lamp includes a first light source operably coupled with a lens. A switch is configured to control an activation state of the first light source. A controller prompts the first light source to generate a low-intensity light of a first color when a night-like condition is detected and a vehicle is in motion and a high-intensity light of a second colorwhen the vehicle is stationary.

An improved illumination apparatus for the dazzle-free illumination of a region monitored by a night vision instrument is provided. The illumination apparatus has an illumination device, which has at least one light-emitting diode chip and a luminous means. The light-emitting diode chip is formed to emit electromagnetic radiation of a first wavelength range. The luminous means is formed to convert the radiation of the first wavelength range into light with light in a second wavelength range. The second wavelength range is shorter than 610 nm.

In a method for avoiding dazzling of a person (10) by a light source (6) arranged in an interior (20) of a vehicle (22), wherein the light source (6) during operation emits light (24) within a beam cone (26), a camera (4) is arranged in the interior (20) and oriented such that at least one monitoring section (28) of the beam cone (26), in which the person (10) can enter, is located in the field of view (30) of the camera (4), the camera (4) records a camera image (32), using machine person detection, it is ascertained from the camera image (32) whether at least one part of the person (10) is located within the beam cone (26), in this case, at least the region (18) of the beam cone (26) in which the part of the person (10) is located is switched to glare-free.

A visual ability improvement device installed in a vehicle includes a noise generator, a surrounding situation detector, a driver status detector, a vehicle status detector, an operation switch, and a noise output device. A controller of the noise generator determines an optimum strength based on the surrounding situation from the surrounding situation detector, the driver's status from the driver status detector, the vehicle's status from the vehicle status detector, and the correspondence of the optimum representative noise to the above situation and statuses from the correspondence memory. Then the controller generates a noise with the determined the optimum representative noise strength, and outputs to the noise output device such as passenger compartment light a control signal which depends on the generated noise.

The invention relates to a light guide installation structure for an ambient lamp for a vehicle, which belongs to the technical field of automotive decorative parts. The light guiding installation structure of the ambient light for vehicles according to the present invention comprises: a body frame of the instrument panel, on which a welding post is arranged, and the end of the body frame has a flanging structure; the first end of the mounting bracket is welded and fixed on the welding post , the second end of the mounting bracket is embedded in the flange structure; the mounting bracket has a U-shaped groove, the ambient light tube is arranged in the U-shaped groove, and the light guide and visible plate is close to the U-shaped groove and snapped in on the mounting bracket. The installation structure of the present invention can be arranged within the field of vision of the driver and passengers, effectively avoiding the problem of excessively bright and dazzling ambient lights of existing vehicle models, and improving user experience and driving safety.

Disclosed herein is a vehicle headlight for improving visibility during operation. In the vehicle headlight, a filtering film capable of preventing glare and reducing a discomfort glare phenomenon by controlling scotopic vision (S) / photopic vision (P) ratio in such a manner as to selectively absorb / block blue light in light emitted from an LED module is adhered, thereby improving visibility during operation.
