  • Patent number: 9052086
    Abstract: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises an inner surface facing the source and an outer surface that is opposite the inner surface. The inner surface can comprise a refractive surface that receives light headed away from the optical axis of the light source, for example opposite the street. The refractive surface can form the received light into a beam. The outer surface of the optic can reflect the beam back across the optical axis, for example so that light headed away from the street is redirected towards the street.

  • Patent number: 9028107
    Abstract: A lamp has an LED, a base, and a reflector. The base is rigidly connected to the LED and has a base contact surface. The reflector, which can be connected to the base, has a reflector contact surface, an entry opening, an exit opening, and a longitudinal direction (L) that runs from the exit opening to the entry opening. The reflector contact surface is arranged in the longitudinal direction (L) between the entry opening and the exit opening, and the base contact surface abuts the reflector contact surface. Thus, movement of the base and/or reflector towards each other is prevented when the reflector is connected to the base. The reflector is formed in such a way that a projection of the reflector contact surface in the longitudinal direction (L) of the reflector is free of undercuts.

  • Publication number: 20150124460
    Abstract: A lens includes an optical axis, a light source recess arranged through the optical axis, a reflection surface crossing through the optical axis, and a critical reflection surface which is arranged in a spaced relationship with the optical axis. The critical reflection surface is arranged between the light source recess and the reflection surface and receives the light from the light source recess and the reflection surface and reflects the light from the light source recess and the reflection surface towards the reflection surface. The emission light of the lens is light emitted forward of the light emitting surface which is reflected via the reflection surface and the critical reflection surface. Therefore, people cannot receive directly light emitted forward of the LED after it cross through the lens. In result, high luminance light from the LED is prevented from ripping into eyes, which achieve the aim of anti-glare.

  • Publication number: 20150092420
    Abstract: An optical system comprising a non-specular ceramic reflector surrounding one or more electrode-less bulbs containing a fill that forms a light-emitting plasma when excited with radio frequency, to be used in a fixture for illuminating subjects, for the purpose of high output lighting, such as lighting for image capture, horticulture, stadium, port, roadway, construction and area lighting. This ceramic reflector generates a uniform lambertian reflection specifically evening out the light emission from the electrode-less bulb producing a uniform beam of light with a spread between about 1 to about 300 degrees. This ceramic reflector greatly increases the amount of light falling on a given subject in comparison to the fixture without said reflector system.
