Abstract: The present disclosure provides a safety light. The safety light includes a top housing; a printed circuit board assembly coupled to the top housing, the printed circuit board assembly having a top surface and a bottom surface; a plurality of light elements coupled to the bottom surface of the printed circuit board assembly, the printed circuit board assembly programmed to energize the plurality of light elements following depression of a first control button; a lens coupled to the bottom surface of the printed circuit board assembly and the plurality of light elements, the lens having a first angled reflective surface and a plurality of side surfaces; and a bottom housing coupled to the lens.

Abstract: The present invention relates to an optical device that includes a light guide; at least a first and a second light source; at least a first and a second optical coupler; and at least one collimator to generate a first collimated light beam and a second collimated light beam. The at least one first optical coupler is configured to receive the first collimated light beam that is directed along a first optical axis towards a first region of the light exit face producing a first photometric function. The at least one second optical coupler is configured to receive the second collimated light beam that is directed along a second optical axis towards a second region of the light exit face producing a second photometric function.

Abstract: Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.

Abstract: An image display device which displays an image to a viewer in front thereof without cross-talk and displays a two-dimensional image in wider space is provided. The image display device which projects an image on the viewer includes; a light source unit which emits light to the viewer; an imaging section in which an image is formed; optical means in which the light emitted from the light source unit is transmitted to enter the imaging section; and a viewing angle controller which diffuses and spreads the light directed to the left eye of the viewer in the left area from the left eye of the viewer, and the light directed to the right eye of the viewer in the right area from the right eye of the viewer.

Abstract: A vehicle lamp assembly includes a transmission axle coupled to a lamp unit, and a drive unit for driving the transmission axle to rotate such that the lamp unit is movable to a selected one of a default position, where the illuminating direction of the lamp unit is parallel to a vehicle axis, and left and right limit positions, where the illuminating direction forms left and right limit angles with the vehicle axis, respectively. A detecting device generates a default position signal when the lamp unit is at the default position. A control device is operable to control the drive unit for restoring the lamp unit to the default position with reference to the default position signal, and for moving the lamp unit according to angular displacement of a vehicle steering linkage system.

Abstract: Use of spiro compounds of formula (I), where K1 and K2 are, independently of one another, conjugated systems, as a laser dye.

Abstract: A method and apparatus for automatically searching a desired track position or one or a plurality of recording regions on an information recording medium which comprises pre-recorded tracks pre-recorded with an information signal and unrecorded tracks. The search is carried out based on the existence and non-existence of a reproduced radio frequency (RF) signal which is reproduced from the information recording medium.
