The present invention relates to an apparatus for controlling the forced light up of brake lights and, more specifically, to an apparatus for controlling the forced light up of brake lights, the apparatus: checking whether a brake light system has problems so as to prevent vehicle rear-ending accidents caused by the breakdown of vehicle brake lights, informing only a driver, according to a state of a vehicle, about each problem, or sensing stepping on the brake and forcedly lighting up the brake lights whenever the driver steps on the brake when the lamp of the brake lights and wiring connected to the brake lights have no abnormalitites, but the breakdown of the brake light system, that is, a brake lights power fuse disconnection, a breakdown of a brake lights relay, a wiring disconnection or defective wiring contact and the like occurs, informs the driver of the stop lamp system breakdown; informing the rear vehicle of danger by flickering a turn signal light since the brake lights cannot be forcedly lit up when both the brake light system and the brake lights have broken down; informing the driver of the breakdown of the brake light system and the brake lights by operating an internal alarm means whenever the driver steps on and releases the brake, thereby enabling the driver to drive safely.

In various embodiments, a lighting device is provided. The lighting device includes at least one light source for emitting primary light, at least one phosphor body which is illuminatable by the primary light and is spaced apart from the at least one light source, and at least one light scattering body which is situated optically downstream of the phosphor body in a light propagation direction of the primary light that is uninfluenced by the phosphor body. The lighting device is designed in the case of an intact phosphor body to generate an illumination pattern by light generated by the phosphor body, and otherwise to generate a light emission pattern by light generated by the at least one light scattering body. The light emission pattern differs from the illumination pattern.

A light-emitting element driving semiconductor integrated circuit constitutes at least part of a light-emitting element driving device that is configured to drive a first and a second light source when the first light source is not short-circuited and drive the second light source when the first light source is short-circuited and that includes an output capacitor. The light-emitting element driving semiconductor integrated circuit has a controller configured to control the resistance value of a variable resistor connected in series with the first and second light sources according to the voltage across a resistor connected in series with the first and second light sources.

A light emitting element driving device includes a first and second driving circuits, an abnormality detecting portion, a bypass path, and a switching portion. The first driving circuit can supply power to a light emitting element in a first mode, and is disabled to supply power in a mode other than the first mode. The second driving circuit can supply power to a light emitting element in a second mode. The abnormality detecting portion detects an abnormality of the light emitting element normally connected to the second driving circuit at least in the second mode. The bypass path connects the first driving circuit to the second driving circuit. The switching portion, is disposed in the bypass path so as to make the bypass path into a conductive state when an abnormality is detected, and to make the bypass path into a cutoff state when an abnormality is not detected.

Systems and methods of providing a DOT Lighting monitor that automatically detects when any of the exterior lights on a commercial motor vehicle fails/burns out and that alerts the driver to which one(s) is affected is provided. Each required light is monitored, and a state of an indicator corresponding to that required light is changed to notify an operator of a failure thereof.

The present disclosure provides an LED straight light including a light tube with two pins at both ends, an LED installed in the light tube and a driving circuit. The driving circuit includes a mains branch and a signal branch. The mains branch is coupled to the pins at one end of the light tube for transmitting power to the LED for power supply. The signal branch is coupled to the pins at the other end of the light tube for transmitting external driving signals to control the on/off of the mains branch. The LED straight light of the present disclosure is powered by two ends, one of the two ends supplies power to the LED through the mains branch, and the other end receives driving signals to control the on/off of the mains branch.

A headlamp system is provided for vehicles with an imaging unit and with an optical unit. The optical unit generates a light distribution that features a plurality of light patches. The light patches are each generated by mapping of at least one light pixel of the imaging unit. An actuator unit includes a corrective mechanism, by which, in event of presence of a defective light pixel that cannot be mapped by the optical unit on a light patch, at least one corrective light pixel is actuated, by means of which a light patch adjacent to the defective light patch not illuminated by the defective light pixel features a changed intensity progression in comparison to non-defective state. At least one flight patch adjacent to the defective light patch features an increased corrective intensity progression in comparison to the non-defective state.
