Room and/or area disinfection apparatuses are provided which generate pulses of germicidal light at a frequency greater than 3 Hz and project the pulses of light exterior to the disinfection apparatuses. In some cases, the apparatus includes processor executable program instructions for receiving data regarding characteristics of a space in which the disinfection apparatus is to be operated. In addition or alternatively, the apparatus may include a remote user interface to affect operation of the disinfection apparatus. In other cases, the apparatus may additionally or alternatively include a means for automatically moving the disinfection apparatus. In yet other additional or alternative cases, the disinfection apparatus may be void of an opaque component 360° around an elongated portion of the germicidal pulsed light source such that light emitted from the germicidal pulsed light source encircles the disinfection apparatus.

Room and area disinfection utilizing pulsed light

Methods and systems are provided which project germicidal light from a lamp toward an individual donned in outerwear to disinfect the outerwear. In specific embodiments, germicidal light is projected toward an individual situated greater than approximately 1 foot from the light source. Some systems include sensor/s for detecting presence of an individual within a target area a set distance from the disinfection apparatus comprising the light source and program instructions for commencing operation of the disinfection apparatus based on information from the sensor/s. In addition or alternatively, some systems include reflective panel/s exhibiting greater than approximately 85% reflectance. In such cases, the systems may include program instructions for determining operating parameters of the disinfection apparatus and/or positions of the reflective panel/s based on information regarding an individual who is in the presence of the disinfection apparatus or who is scheduled to be in the presence of the disinfection apparatus.

Pre-doffing disinfection systems and methods

Room and/or area disinfection apparatuses are provided which generate pulses of germicidal light at a frequency greater than 3 Hz and project the pulses of light exterior to the disinfection apparatuses. In some cases, the apparatuses include an occupancy sensor for determining presence of an individual in a region extending at least 1.0 meter from the disinfection apparatus and processor executable program instructions for inhibiting and terminating the generation of light from the light source upon the occupancy sensor detecting presence of an individual. In addition or alternatively, the apparatuses may include wheels to affect portability of the apparatus. In some cases, the apparatuses may additionally or alternatively include an actuator for moving the light source relative to a support structure of the disinfection apparatus and processor executable program instructions for activating the actuator while the light source is emitting light.

Smoke detector shields for blocking or minimizing the transmission of light therethrough and methods for use are provided. According to one embodiment, a method for shielding a smoke detector includes shielding at least a portion of a smoke detector operationally arranged within a room, and subsequently activating a light emission device arranged within the room, while shielding the smoke detector. In order to exclude light emission devices, which are commonly used within a room for lighting and/or communication purposes, the light emission device set forth in the method is configured for generating infrared light at a radiant intensity greater than approximately 1 W/sr, and/or ultraviolet light at a radiant intensity greater than approximately 1 W/sr, and/or visible light at a luminous flux greater than approximately 3000 lumens. Embodiments of smoke detector shields that prevent such light from penetrating the housing of a shielded smoke detector are provided herein.

Smoke detector shields and related methods

Smoke detectors and smoke alarms are provided which have one or more light shields configured to block or minimize the transmission of ambient light to their light receivers. Light shield configurations for facilitating such functionality are provided as well. The shield/s include a material which attenuates a majority amount of light within a particular range of light that a light source of the smoke detector may be configured to only emit and/or the range of light the light receiver may configured to only convert to photocurrent. In some cases, the shield/s surrounds the light source and/or the light receiver arranged external to an interior chamber of the smoke detector. In some cases, the shield/s may at least partially span a connection side of an external housing of the smoke detector. Alternatively, the shield may be arranged in a space between the interior chamber and the connection side of the housing.

Disinfection methods and apparatuses are provided which generate pulses of germicidal light at a frequency greater than 20 Hz and project the pulses of light to surfaces at least 1.0 meter from the disinfection apparatus. The pulses of light comprise a pulse duration and an energy flux sufficient to generate a power flux between approximately 200 W/mand approximately 5000 W/mof ultraviolet light in the wavelength range between 200 nm and 320 nm at the surfaces. Other disinfection methods and apparatuses are provided which generate pulses of light comprising germicidal light and visible light from a germicidal light source and generate pulses of light from a visible light source that is distinct from the germicidal light source. The projections of visible light from the light sources produce a continuous stream of visible light or a collective stream of visible light pulsed at a frequency greater than 60 Hz.
