G08B 13/196 - Actuation by interference with heat, light, or radiation of shorter wavelength; Actuation by intruding sources of heat, light, or radiation of shorter wavelength using passive radiation detection systems using image scanning and comparing systems using television cameras
Provided is a lightbulb that is configured such that the light source of the lightbulb has a reduced visibility. This is achieved by the provision of a lens arrangement comprising an outer convergent lens. The outer convergent lens converges light rays that enter the outer convergent lens at a same first angle to establish a shadow region. The shadow region is a volume in the lightbulb in which light rays incident to the outer convergent lens at a first angle may not be incident. Put another way, light rays input at the first angle may avoid the shadow region. Thus, by positioning the light source at least partially within the shadow region, the light source may be obscured when viewed from certain viewing angles. In this way, an aesthetic appeal of the lightbulb may be improved, as the light source is not visible from some viewing angles.

A method of power sharing between at least two lighting devices located in an outdoor environment, wherein each of the at least two lighting devices comprises an energy storage element arranged for providing power to the respective at least two lighting devices; and wherein the at least two lighting devices are connected to each other via an electric conductor; wherein the method comprises determining a state of charge, SoC, and/or voltage of the energy storage elements of the at least two lighting devices, controlling a first lighting device of the at least two lighting devices to operate in an up-stream mode if the SoC and/or voltage of the respective energy storage element exceeds a threshold, and controlling a second lighting device of the at least two lighting devices to operate in a down-stream mode if the SoC and/or voltage of the respective energy storage element does not exceed the threshold, wherein the second lighting device is arranged for communicating the operating mode to at least one lighting device of the at least two lighting devices, inferring an occupancy pattern in proximity of each of the at least two lighting devices based on historical occupancy data; and if the first lighting device have been detected to be operating in an up-stream mode, sharing power, via the electric conductor, from the first lighting device to the second lighting device based on the inferred occupancy.
An illumination module and illumination systems incorporating such modules are provided. The illumination systems include a housing body that secures one or more arrays of illumination modules, with each array of illumination modules comprising one or more individual illumination modules. Specifically, each illumination module can include: a retaining cup having a first end, a second end, and a sidewall extending from the first end to the second end, where the second end of the retaining cup defines an exit aperture of the illumination module; a light source disposed on a portion of a first surface of a light source board, wherein the portion of the first surface of the light source board covers the first end of the retaining cup; and a total internal reflection (TIR) optical device having an optical film, the TIR optical device being disposed within the retaining cup and abutting the light source.
