LIGHTING DEVICE FOR VEHICLE
A lighting device for a vehicle includes a light source device; a main lens; a reflective fluorescent body configured to reflect and convert wavelengths of incident beams; and a prism arranged between the main lens and the reflective fluorescent body. The prism is configured to: reflect beams emitted from the light source device to be incident on the reflective fluorescent body; and transmit, through the prism and to the main lens, beams reflected from the reflective fluorescent body. The prism includes: a first surface facing the reflective fluorescent body; a second surface through which beams are incident; and a third surface forming an acute angle with the first surface. The prism is configured such that the beams incident through the second surface of the prism form angles of incidence, with respect to the third surface of the prism, that are greater than a critical angle of the prism.
LIGHTING DEVICE FOR VEHICLE
A lighting device for a vehicle includes a lens; a prism that is disposed on a rear side of the lens and that is configured to totally reflect an incident light and to then emit the light; a light source device configured to emit light toward the prism; and a reflective fluorescent body disposed on the rear side of the lens and configured to convert a wavelength of light emitted by the prism and to then reflect the wavelength-converted light to the lens. The prism includes an emitting surface that is spaced apart from an optical axis of the lens. A distance between the reflective fluorescent body and a rear surface of the lens is greater than a distance between the emitting surface of the prism and the rear surface of the lens.
SYSTEMS AND METHODS FOR DYNAMIC LIGHT CONTROL
A light system for an aircraft is provided. A light system may include a sensor and a first aircraft light. A controller may be coupled to the sensor and the first aircraft light and may perform operations including receiving data from the sensor, determining a status of the aircraft based on the data, and controlling the first aircraft light based on the status of the aircraft. The first aircraft light may include an external aircraft light and the operations may further include at least one of activating or deactivating the external aircraft light based on the status of the aircraft.
LIGHT ASSEMBLY WITH LED STRING
A light-emitting diode (LED) string includes an electrically conductive wire and a plurality of LEDs. The LEDs are electrically connected to the wire in series along an axial length of the wire. The LED string may include a solder layer, with the LEDs electrically connected to the wire via the solder layer. A tube having an optional phosphor coating may circumscribe the wire and LEDs. When connected to a surface, the LED string emits light in a band of at least 180 degrees with respect to the surface. A light assembly includes a first surface and a first LED string configured as set forth above. The light assembly may include a second LED string positioned with respect to the surface and having additional LEDs configured to illuminate in response to a second control signal from the controller.
ANTI-GLARE SYSTEM FOR VEHICLES
An anti-glare system for vehicles has a linear polarized filter mounted to a headlight of a vehicle with the positive side of the filter placed at a 135 degree angle relative to a horizontal line. A second linear polarized filter is mounted to a windshield of the vehicle with the negative side of the second filter placed at an angle of 45 degrees relative to a horizontal line. When vehicles equipped with this anti-glare system meet travelling in opposite directions, the polarized light emitted by the headlight of one vehicle is blocked by the filter installed in the windshield of the other vehicle. A third linear polarized filter may be mounted to rear and side view mirrors of the vehicle with the positive side of the third filter placed at an angle of 135 degrees relative to a horizontal line. When vehicles equipped with the anti-glare system meet travelling in the same direction, the polarized light emitted by the headlight of one vehicle is blocked by the filter installed in the rear or side view mirror of the other vehicle.
CLIP UNIT AND EDGE MOUNTED LIGHT EMITTING DIODE (LED) ASSEMBLY COMPRISING A CLIP UNIT
A clip unit and an edge mount light emitting diode (LED) assembly comprising a clip unit. The clip unit provides a mounting structure for mounting a light source, such as an LED, to an edge of a printed circuit board (PCB). A surface mount LED, for example, can thus be easily mounted to the edge of the PCB so as to project light in a direction normal to the edge surface of the PCB, instead of the typical mounting orientation that allows for the projection of light normal to the primary surface of the PCB. The clip unit includes an anode retention clip and a cathode retention clip which are electrically isolated from one another within an insulative housing portion.
BRAKE LIGHT ASSEMBLY
An improved brake light assembly is a brake light with a housing and internal light emitting diodes for attachment in the back window of a vehicle that illuminates when the brake pedal is depressed. When the Light Emitting Diodes are illuminated, the words “No Texting” are formed.
LIGHTING DEVICE OF VEHICLE
Disclosed is a lighting device of a vehicle capable of achieving an enhancement in luminous efficacy. The disclosed lighting device includes a light source for generating light, a light guide including a light emitting portion formed with first patterns arranged in a longitudinal direction of the light emitting portion, to guide the light, the light emitting portion performing light emission using the light, and a light receiving portion to receive the light generated by the light source, and a back cover, on which the light guide is mounted. The back cover is formed with second patterns arranged in a longitudinal direction of the back cover at a portion of the back cover, on which the light receiving portion is mounted. The first patterns are formed to have a greater width with increasing distance from the light source. The second patterns are formed to have the same width.
Lighting device with multiple-region reflector
Lighting devices that comprise a light source and a reflector, the reflector comprising first, second and third reflector regions. In some devices, a first portion of light is reflected by the first region and then by the third reflector region, a second portion of light is reflected by the second region and forms a primary beam, and at least 5% of the first portion of light that is reflected by the third region is within the primary beam of light. In some devices, at least 5% of all light reflected by the first reflector region travels from the first reflector region directly to the third reflector region. In some devices, at least 5% of all light reflected by the third reflector region traveled directly from the first reflector region to the third reflector region. In some devices, the reflector comprises means for providing the features described above.
Light module with two or more reflectors for a motor vehicle
The invention relates to a light module (1) for a motor vehicle or for a motor vehicle headlamp, wherein the light module (1) has at least two or more light sources (10, 11), which are positioned in defined positions relative to one another, and wherein the light module (1) also has two or more reflectors (20, 21), wherein at least one reflector (20, 21) is associated with each light source (10, 11), wherein at least one of the reflectors (20, 21) is movably connected to at least one adjacent reflector (20, 21).
