An LED retrofit lamp is described. The LED retrofit lamp includes LEDs arranged into at least a first group of LEDs and a second group of LEDs, power contacts, an interface and a controller. The power contacts receive electrical power to operate the LEDs. The interface supplies control signals to operate one or more of the first group and the second group of LEDs. The controller receives the control signals and operates the first group of LEDs and the second group of LEDs independent from each other based on the received control signals.

A lighting apparatus includes a light source part having a first light source and a second light source provided away from the first light source, a reflective part provided away from the first light source and second light source and reflecting light emitted from the first light source and second light source, and a support part facing the reflective part and supporting the light source part. The reflective part includes a plurality of reflective plates which are continuously provided. Each of the reflective plates provided adjacent to one another has a reflective surface which is shaped differently from one another.

The invention provides a method for managing image data in a motor vehicle lighting system, the lighting system including at least one lighting module intended to project light beams, the light beams being generated from data relating to the selection of at least one image, each image being respectively defined by a matrix including a plurality of horizontal or vertical rows of pixels, with each pixel having a numerical value related to a light intensity of the pixel. The method includes determining whether the pixel under analysis is considered to be a significant point of inflection of the image, so as to transmit it to at least one lighting module, so that it is able to project a resulting image.

Disclosed is a condenser and a high-and-low-beam integrated vehicle lamp module, the condenser comprises at least one light incident portion, a light-transmitting portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light-transmitting portion; the 50L dark area light shape forming structure protrudes from a surface of the light-transmitting portion and has a slope surface; and the distance from the slope surface to the surface of the light-transmitting portion gradually increases from a position close to the light incident portion to the light emergent portion. Since the 50L dark area light shape forming structure protrudes out of the surface of the light-transmitting portion and has the slope surface, in a high-beam illumination mode, some light is emitted from the 50L dark area light shape forming structure to a 50L test point.

A vehicle light guide body includes an incident surface that light from the light source enters, a first reflective surface that internally reflects the light that has entered from the incident surface to form nearly parallel light, a second reflective surface that internally reflects the light from the first reflective surface, a third reflective surface provided in a position located in front of the second reflective surface in a front-rear direction and in a portion in at least one of end faces in a left-right direction, a light shielding part that shields a part of the light reflected by the second reflective surface, and a light emitting surface that emits the light that has been internally reflected by the second reflective surface and has passed through the light shielding part to illuminate a headlight pattern in front of a vehicle.

Disclosed are a primary optical structure, a high-beam lighting device, and an anti-glare high-beam light. The primary optical structure comprises a reflection unit and a shading structure located in front for blocking part of the reflected light from the reflection unit. The primary optical structure is configured for use in a left vehicle lamp or a right vehicle lamp, where the shading structure is arranged at a left side portion or a right side portion of the lamp, respectively. The light blocked by the shading structure and the light that is not blocked are bounded by a right side edge or a left side edge respectively, and an upper side edge of the shading structure. In a vehicle lamp, the primary optical structure can form a high-beam profile having a dark area to prevent glare, such that the dark area formed has an adjustable width and position, improving driving safety.
