The present invention is directed toward a device that allows auxiliary lights to be mounted to a side view mirror of a motor vehicle. The device includes a shell which is custom manufactured to conform to a shape of a cover of a sideview mirror on a particular make, model, and year of a motor vehicle. The shell is configured to house one or more auxiliary light elements which can be chosen by a motor vehicle owner. The device also includes one or more air passage sections configured on the shell formed to direct air into an interior of the shell to cool the auxiliary light elements. The device also includes one or more through openings configured on the forward-facing side of the shell to which one or more light covers may be positioned over and arranged in front of the auxiliary light elements.

A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

A lighting apparatus includes a light passing cover, a light strip, a heat dissipation plate, a manual switch, a driver and a bottom cover. The light passing cover defines first elongated cavity. The light strip is mounted with multiple LED modules. The heat dissipation plate is used for mounting the light strip on a first side of the heat dissipation plate. The manual switch is disposed for selecting a switch setting. The manual switch is placed on the first side of the heat dissipation plate. The driver converts an external power source to a driving current supplied to the multiple LED modules. The driver is electrically connected to the manual switch for controlling the driving current supplied to the multiple LED modules to adjust an output light of the multiple LED modules according to the selected switch setting. The bottom cover defines a second elongated cavity.

Optical lenses and associated luminaire are described herein. In one aspect, a lens comprises a light receiving side comprising grooves for receiving light emitting diodes, the grooves defined by a central refractive region and walls comprising total internal reflection faces; and a light extraction side opposite the light receiving side, the light extraction side comprising refractive extraction surfaces, total internal reflection extraction surfaces, or combinations thereof. In some embodiments, luminaire comprises an array of light emitting diodes; and the lens positioned over the array of light emitting diodes.

An LED lighting device or LED lamp comprising one or more LED packages; and a switch control unit is provided. The switch control unit is configured to operate the one or more LED packages. The switch control unit is in communication with a sensor located in a space, the LED lighting device or LED lamp also being located in the space. The switch control unit is configured to (i) receive a sensor signal from the sensor, (ii) process the sensor signal, (iii) determine an adjustment to the operating light qualities of the LED lighting device or LED lamp based on the processing of the sensor signal and one or more goal light qualities corresponding to the space, and (iv) adjust the operation of the one or more LED packages in accordance with the adjustment.
