Abstract: A method of personalizing a vehicle lamp includes drawing an image made up of a plurality of pixels that implement a vehicle lamp, based on an input by a user. The method also includes converting the drawn image into light-and-shade data that correspond to the pixels, respectively, multiplying a pixel light distribution value, corresponding to each pixel, by a weighted value based on the data resulting from the conversion, adding up results of the multiplication, and deriving total light distribution of the pixels that results when brightness of the vehicle lamp is the same as that of the drawn image. The method further includes comparing the derived total light distribution against a predetermined reference value and determining whether the derived total light distribution satisfies a predetermined light distribution reference, and applying the drawn image to the vehicle lamp when it is determined that a predetermined light distribution reference is satisfied.

Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

Abstract: The present disclosure relates to a grill lighting lamp system and includes a grill part provided in a vehicle and an optical device configured to irradiate light to the grill part. The grill part includes a plurality of reflection portions configured to reflect the light irradiated from the optical device toward the outside of the vehicle and an invalid portion provided in a stepped shape between the plurality of reflection portions and configured to absorb glare light not reflected forward among light incident on the reflection portion from the optical device. According to the present disclosure, it is possible to minimize damage to the optical device in the event of a front collision of the vehicle and suppress a glare phenomenon from occurring upon grill lighting.

Abstract: A leveling apparatus for a vehicle headlamp includes: a housing disposed at a front side of a vehicle; a light source module disposed in the housing to emit light; a tilting sensor disposed in the housing to detect an inclination degree of a road; a tilting means to tilt the light source module and the tilting sensor together; and a controller. The controller receives a signal detected by the tilting sensor and controls the tilting means based on the inclination degree of the road to adjust a light emission angle of the light source module. In addition, the tilting sensor operates until a sensed output of the tilting sensor reaches a normal range.

Abstract: A lamp system applied to a vehicle according to the present disclosure is provided with any one of a reflector, an optical member, a digital micromirror display (DMD), a shield, or a shield optical module, and combined with a rotation light source device for generating light of a specific LED turned on at a synchronized rotation position of one or more LED chips of first to Nth LED chips (N is an integer of 2 or more) per one rotation while being rotated by a current application of a signal transmitter receiving a lamp turn-on signal of the vehicle, thereby generating various lighting patterns even while eliminating all problems of increasing the layout/decreasing the light amount/increasing the amount of property changed, lowering the reflection efficiency/transmission efficiency, and losing the optical efficiency with the circular LED array.

Abstract: A hidden lighting lamp uses a color conversion material and is applied to a vehicle. A color conversion member is spaced apart from a light source by a light source air gap (La) such that the color conversion member is integrally engaged with a lens for projecting light of the light source to the outside or such that the color conversion member is spaced apart from the lens by a lens air gap (Lb). Hidden lighting without deterioration of optical efficiency of LED light from the light source is thereby implemented. One or more of a black painting, a coating layer, an application layer, and a deposition layer are provided, thereby providing concealment of the lamp inner space of the lens, anti-peeling of a deposit, and diversity of fluorescent color.
