A light emitting apparatus includes at least one first light source and at least one second light source. The at least one first light source and at least one second light source may be configured to emit white light and cyan light, respectively, such that a ratio of luminous flux of the white light to luminous flux of the cyan light ranges from 19:1 to 370:1, based on a common magnitude of electrical current being applied to each of the at least one first light source and the at least one second light source.

A lighting device having a first configuration wherein a first light source is exposed and a second light source is covered and a second configuration wherein the first light source is exposed and the second light source is exposed. The light device is enclosed in a rigid enclosure securing the lighting device in the second configuration. A power source is electrically coupled to the lighting device to provide power to the first light source and the second light source. A switch is coupled to the power source and the first and second light sources. The switch is configured to permit propagation of power from the power source to the second light source when the lighting device is in the second configuration.

An automated headlight system for vehicles replaces the high and low beam with a continuum of beam patterns, with further variable spatial distribution of intensities and color spectrum. The digital-headlight is comprised of a controller, sensors and multiple, individually-controllable light-sources modified by optical-control elements to form narrow-beams which are then combined to create the overall headlamp beam. Utilizing real-time sensor data regarding beings, objects and vehicles in the way-ahead, as well as optional information on the driver, vehicle and environment, the logical controller dynamically adapts the headlight system's illumination so as to provide vehicle operators with optimal visibility while preventing discomfort-glare from reaching the eyes oncoming traffic or pedestrians.

There is provided a lighting device (100) comprising a housing comprising a frangible light exit window (110) and a fitting (120) including a first electrical connector (122) inside said housing. Within the housing there is a carrier assembly (130) comprising a plurality of SSL elements (132), and a second electrical connector (134) in contact with the first electrical connector (122). The second electrical connector (134) is held in contact with the first electrical connector (122) by the light exit window (110). This lighting device is relatively safe as if the light exit window (110) breaks the electrical components of the carrier assembly (130) may not be live.

A lighting device configured to deactivate dangerous pathogens (e.g., MRSA bacteria) in an environment. The lighting device includes at least one lighting element with a single light source configured to provide light. At least a first component of the light comprising light having a wavelength of about 405 nm, and at least a second component of the light comprising light having a wavelength of greater than 420 nm. The first component of light has a minimum integrated irradiance of 0.01 mW/cm.sup.2 measured from any unshielded point in the environment that is 1.5 m from any point on any external-most luminous surface of the lighting device.

Methods and lighting systems to deactivating deactivate MRSA bacteria in a volumetric space over a period of time. At least one lighting element of each of one or more lighting fixtures provide light. The light includes a first disinfecting light having a wavelength of about 405 nm and a minimum integrated irradiance of 0.01 mW/cm.sup.2, and a second component having a wavelength of greater than 420 nm. The one or more lighting elements of the one or more lighting fixtures apply a determined total radiometric power to produce a desired power density measured at any exposed surface within the volumetric space during the period of time. The minimum power density includes a minimum integrated irradiance of the disinfecting light equal to 0.01 mW/cm.sup.2.

An electronics platform assembly for a light fixture includes an electronics platform with a least one tray. The electronics platform assembly is electronically autonomous and includes at least one electronic component mounted on at least one of an upper surface or a lower surface of the electronics platform. In various examples, the electronics platform has a profile such that the electronics platform is positionable in a fixture housing of a light fixture. In some aspects, an electronics platform for a light fixture includes an upper tray and a lower tray wherein at least one air gap is defined between a portion of the upper tray and a portion of the lower tray.

A replacement LED insert module for retrofitting a pre-existing shoe box parking lot light. The module includes a plate into which an array of LED light fixtures capable of being operated directly from an AC power supply are mounted. The module is configured for attachment to a flange in the pre-existing shoe box parking lot light after the innards of the pre-existing light (bulbs, any reflectors, ballasts, etc.) have been removed.

The present invention relates to a lamp comprising at least one OLED lighting means lying flat on an at least partially light-transmissive carrier plate (13) and formed as an OLED panel (14, 15, 16), in which at least two contact shoes respectively assigned to an OLED panel are attached on the rear side of the carrier plate that is facing away from the light-emitting side and respectively comprise means for contacting one pole each of the OLED panel. The solution according to the invention provides a lamp that ensures effective coupling out of the light emitted by the OLEDs and uniform distribution of the light over the light-radiating area of the carrier plate and at the same time is of a comparatively simple construction and an attractive design. The lamp according to the invention may for example be a pendant lamp, a suspended lamp, a surface-mounted ceiling lamp, a recessed ceiling lamp, a standard lamp or a table lamp.
