BLACK IMAGE TYPE HIDDEN LIGHT LAMP AND VEHICLE HAVING THE SAME
20230075681 · 2023-03-09 ·

A black image type hidden light system applied to a vehicle is composed of a control module coupled to a hidden lamp module in which an outer lens, an inner lens, and a light source are assembled in a lamp housing, and a black color surface of the outer lens covers an inner space of the lamp housing to block the exposure to the outside and transmits the light fully reflected to the inner lens to the outside, thereby forming a deposition image in black when not lit and a lamp image or a lighting image when lit, and in particular, optimizes a light transmittance with an amount of addition of a carbon black material mixed with a polycarbonate (PC) material, thereby substantially enabling the mass-production beyond the limitation of an AL deposition image.

LED Headlamp System with Brightness Control

A headlamp illumination source that switches from a first configuration conforming to on-road illumination standards to a second configuration that does not conform to on-road illumination standards. The switching is preferably controlled by a wireless signal but in some embodiments the switching can be controlled by a hard-wired signal or by a switch proximate the illumination source itself.

Automotive lamp

A lighting circuit turns on multiple semiconductor light sources. Multiple current sources are each coupled in series with a corresponding one from among the semiconductor light sources. A switching converter supplies a driving voltage V.sub.OUT across each of multiple series connection circuits formed of the multiple semiconductor light sources and the multiple current sources. A converter controller controls a switching transistor of the switching converter based on a relation between a voltage across one from among the multiple current sources and a reference voltage having a positive correlation with the temperature T.sub.j.

LIGHT DISTRIBUTION CONTROL DEVICE
20230122166 · 2023-04-20 · ·

A light distribution control device can perform diffused light distribution control designed to widen an irradiation range of a headlamp of an own vehicle. The light distribution control device is equipped with a recognition unit that recognizes a situation around the own vehicle, and a control unit that performs diffused light distribution control when a curve section in front of the own vehicle in a traveling direction thereof is detected, from a result of recognition by the recognition unit. The control unit controls the headlamp such that a non-required irradiation region where irradiation with light is not required is restrained from being irradiated with light and that a region other than the non-required irradiation region is irradiated with more light, when the non-required irradiation region is detected in the irradiation range of the headlamp in performing diffused light distribution control, from the result of recognition.
