Suitable lighting conditions can be provided for a working environment while protecting the circadian neuroendocrine systems of those occupying the illuminated workplace during the night. Lighting systems, methods, and devices can provide substantive attenuation of the pathologic circadian disruption in night workers. Lighting systems, methods, and devices can attenuate the specific bands of light implicated in circadian disruption. LED lighting systems, methods, and devices can provide increased intensity at a different portion of the spectrum than conventional LEDs, providing a useable white light even when unfavorable portions of the wavelength are attenuated by a notch filter. LED lighting systems, methods, and devices can switch between a daytime configuration and a night time configuration, wherein the daytime configuration provides unfiltered light and the night time configuration provides filtered light.

An indoor-outdoor novelty device which simulates moving open flame from the upper end of a standing torch. The device provides a realistic illusion of a bright flame changing its shape and brightness pseudorandomly thru a unique combination of lighting, motion, and airflow under microcontroller control. The device can be viewed from a vantage point in a 360-degree perimeter around the device without compromise to the effect.

A modular system may include a plurality of magnets that may be provided to self-align a casing with an accessory. Self-alignment of the casing and the accessory may provide a secure connection of the casing with the accessory. At least one detent and at least one locking arm may mate and lock the casing against the accessory in a mounted position. The at least one detent and the at least one locking arm may unlock in an insertion position. Self-alignment may occur when a first set of magnets attracts a second set of magnets in which opposite polarities attract and automatically initiate movement of the casing towards the accessory.

The present invention relates to a lighting unit which is simple manufacturing, installation.

Installed on the highways floor and other roads and is suitable for most of the countries of the world.

The existing road lighting depends on the lighting installed on long poles that depend on regular electricity or solar energy, and both methods require very high costs and long, arduous and expensive work stages as well.

Therefore, we find most of the highways and other travel roads are not lighted.

In some case cars crash into the lighting poles, that means more dangerous.

The present invination discloses a lighting unit fixed on ground, between the paths and depends on Sun light, consists of hollow metal body (1) and monocrystalline solar panels (6), Electronic circuit (5), light sensor (13), humidity sensor (14), LED lights (7a and 7b) in the two sides left and right directed to the paths.

LED colored lights (10-a) and (10-b) fixed on the front and rear sides to show the frontiers of the paths in case of fog or raining or snowing.

The base (2) is under the body (1). They are fixed together by screw through holes (12).

In the bottom there is a hollow cylinder implanted into ground and it is a depot for the batteries pack (4).

The present invination is insulated as international standard (IP68).

The present invention increases safety on various types of land travel roads and suitable for most countries of the world and its cost is low and its installation is very easy because it is placed instead of the Cat's eyes and is installed in the same way as Cat's eyes insallation.

This means that land travel roads in most regions of the world will be lighted and safer.

A method for controlling a lighting system of a host motor vehicle with a plurality of selectively controllable elementary light sources, each able to emit an elementary light beam with the vertical angular opening of which is less than 1°. The method includes detecting a target object by a sensor system. Determining a vertical angle between a given point of the sensor system of the host vehicle and a detected point of the target object. Determining, from the vertical angle, a lower angle and an upper angle between a given point of the lighting system and, respectively, an upper cut-off and a lower cut-off intended to together vertically border the target object. Controlling the elementary light sources to emit a pixelated road light beam, as a function of the lower and upper angles, to generate, in the light beam, a dark area extending substantially between the upper and lower cut-offs.

A vehicle lighting apparatus comprising a headlight module comprising a light collecting part, a reflection part, a light outlet part, a first optical channel, and a second optical channel arranged in sequence along a light emitting direction, the first optical channel connecting the light collecting part and the reflection part, the second optical channel connecting the reflection part and the light output part, the connecting position of the lower surface of the second optical channel and the light output part provided with a low beam cut-off line structure for forming a low beam bright-dark cut-off line, the light collected by the light collecting part emitted toward the light outlet part after reflection by the reflection part. The present headlight module is miniaturised and has a high rate of light utilisation.

A device including a phosphor layer having a plurality of holes or pockets arranged within the phosphor layer to reduce lateral light transmission. The phosphor layer can be sized and positioned to extend over a plurality of LED emitter pixels.

Disclosed are a headlamp optical element, a vehicle lamp module comprising the headlamp optical element, a vehicle lamp, and a vehicle. The headlamp optical element comprises a light collecting portion, a first light emitting portion and a reflecting portion, or comprises the light collecting portion, the first light emitting portion, the reflecting portion and a second light emitting portion. The light collecting portion can converge the incident light and emit the light via the first light emitting portion, with some of the light directly emitted to the second light emitting portion, and the rest of the light being reflected by the reflecting portion and then emitted to the second light emitting portion. The reflecting portion is connected to the lower portion of the first light emitting portion, with a lower beam cut-off line structure being formed at the other end thereof, or the reflecting portion is connected to the upper portion of the first light emitting portion, with a high beam cut-off line structure being formed at the other end thereof. The light emitting surface of the first light emitting portion is formed of multiple step surfaces with segment differences or is a single curved surface.

Alighting apparatus can include a light emitting element that can irradiate light, and an optical conversion layer disposed on the light emitting element for converting the irradiated light.

This application discloses a microphone that includes a handle portion, a control portion, and a microphone head that are connected in sequence. The control portion includes a first circuit board and multiple light-emitting assemblies arranged along a perimeter of the control portion. The first circuit board is electrically connected to the multiple light-emitting assemblies for controlling the multiple light-emitting assemblies to emit light in a preset light-emitting mode. In the solution of this application, multiple light-emitting assemblies are arranged in the control portion, so that when in use, the color of the light and the brightness of the light-emitting assembly can be automatically changed according to the microphone song or through a control button, so that the multiple light-emitting assemblies of the microphone can illuminate in a preset manner.
