摘要： An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75) layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

摘要： A multi-color LED illumination device and specifically a lens comprising a cylindrical opening extending into the lens from a light entry region at which one or more LEDs are configured. A concave spherical surface extends across the entirety of the light exit region of the lens, and a TIR outer surface shaped as a CPC extends between the light entry region and the light exit region. There are various diffusion surfaces placed on the sidewall surface of the cylindrical opening, as well as its upper planar surface and, depending on whether glare control is not needed, the exit surface of the lens. Lunes can also be configured on the sidewall surfaces of the cylindrical opening and if lessening glare is needed, also on the TIR outer reflective surface. The combination of lunes, diffusion elements, and the overall configuration of the lens provides improved color mixing and output brightness.

摘要： A lighting attachment for a flagpole includes at least one reflector that directs light from a light source to illuminate front and rear faces of the flag. In one embodiment, the reflector has at least one concavely dished parabolic surface. In another embodiment, the reflector is held in a sleeve that rotates about the flagpole in response to flag movement. In still another embodiment, a swivel connector is fastened to the top of the flagpole and a lower lighting unit to illuminate a flag is rotatably engaged around the flagpole. In yet another embodiment, a rotatable flag bracket is held in an outer groove of a sleeve of the finial attachment, and a finial globe is illuminated by a light source. The housing for the lighting attachment and/or the finial attachment may include at least one power source, such as solar panels and associated energy accumulators (e.g., batteries).

摘要： A light-emitting apparatus for facilitating the growth of one or more plants. The apparatus has a light-emitting layer comprising one or more light-emitting diodes for emitting light, and at least one optical-transformation layer having one or more optical-transformation units. Each optical-transformation unit has a metasurface for adjusting one or more parameters of the light emitted from the light-emitting layer. In some embodiments, the light-emitting apparatus may further have a polarization-control layer sandwiched between the light-emitting layer and the optical-transformation layer.
