Abstract

The system of the present application is a switching system for LEDs which prevents breakdown of the system LED driver when switching between LEDs. The system switches between a first LED sting and a second LED string utilizing an LED driver, at least one LED module, a driver input, at least one pair of switching inputs and a switching module such that the first and second LED strings are activated by the switching module at all times, and each of the first and second LED strings operate with a driver output voltage within a voltage-current operating range of the LED driver. This allows the use of different sets of LEDs without requiring duplication of other system components.

Abstract

A lighting device and methods thereof to inactivate viruses in an environment. Particularly, systems and methods demonstrate the virucidal effects of 405 nm irradiation to inactivate viruses including SARS-CoV-2 and influenza A H1N1 virus, specifically in the absence of exogenous photosensitizers, despite previous efforts in the field suggesting the need for one or more photosensitizers to achieve successful inactivating effect. Moreover, systems and methods implement the 405 nm in the context of lighting devices that may disinfect an environment while providing a combined light output that is unobjectionable to humans.

Abstract

A method of providing doses of light sufficient to deactivate bacteria throughout a volumetric space. The method includes: (1) receiving data associated with a desired illuminance level for the space, indicative of an estimated occupancy of the volumetric space over a pre-determined period of time, and indicative of dimensions of the space; (2) determining, based on the received data, an arrangement of one or more lighting fixtures in the volumetric space, the one or more lighting fixtures configured to at least partially emit disinfecting light having a wavelength of between 400 nm and 420 nm, and a total radiometric power to be applied via the one or more lighting fixtures to produce a desired power density at any exposed surface within the volumetric space during the period of time; and (3) installing the determined arrangement of one or more lighting fixtures in the volumetric space.

Abstract

A light panel for a luminaire includes a frame, a lamp assembly carried by the frame, a dissipater heat sink carried by the frame, and a heat transfer line that thermally couples the lamp assembly to the dissipater heat sink. The heat transfer line transfers heat generated by the lamp assembly, for example by a light element of the lamp assembly, to the dissipater heat sink by conduction. The dissipater heat sink is exposed to an exterior side of the frame such that heat from the lamp assembly is dissipated to the exterior side of the frame by conduction through the heat transfer line and the dissipater heat sink. The light panel may form a door for a housing of a luminaire, which may be easily retrofitted to the housing.
