摘要： The present disclosure is directed to a lens system having a LED, a first lens and a second lens that are aligned along a central optical axis, a housing, and an aperture positioned within the housing, which enables the lens system to provide an illuminated plane having a selected illumination profile in a region of interest, namely an illumination profile that is a uniform or flat field. The present first and second lenses are selectively paired and positioned in the housing to project a light output that is parallel or non-divergent. In another aspect, the present disclosure is directed to a method that generates light from a light source that passes through a first lens and then a second lens, and determines a location of an illuminated plane that is positioned a specified distance from a proximal surface of the second lens to produce a selected illumination profile.

摘要： A lighting apparatus includes a first light source, a second light source, a driver circuit, a main housing and a switch trigger. The switch base is coupled to the driver circuit. The house opening is disposed on a back side of the main housing. The back side of light source plate faces to the back side of the main housing. The switch trigger having a first end coupled to the switch base. The switch trigger extends through a plate opening of the light source plate to pass through the house opening to be operated by a user from the back side of the main housing. The switch trigger is operated to change a setting status of the switch base so as to change a light parameter for the driver circuit to control the first light source and the second light source.

摘要： Systems for apparatuses formed of light emitting devices. Solutions for controlling the off-state appearance of lighting system designs is disclosed. Thermochromic materials are selected in accordance with a desired off-state of an LED device. The thermochromic materials are applied to a structure that is in a light path of light emitted by the LED device. In the off-state the LED device produces a desired off-state colored appearance. When the LED device is in the on-state, the thermochromic materials heat up and become more and more transparent. The light emitted from the device in its on-state does not suffer from color shifting due to the presence of the thermochromic materials. Furthermore, light emitted from the LED device in its on-state does not suffer from attenuation due to the presence of the thermochromic materials. Techniques to select and position thermochromic materials in or around LED apparatuses are presented.

摘要： An emission enhancement structure having at least one energy augmentation structure; and an energy converter capable of receiving energy from an energy source, converting the energy and emitting therefrom a light of a different energy than the received energy. The energy converter is disposed in a vicinity of the at least one energy augmentation structure such that the emitted light is emitted with an intensity larger than if the converter were remote from the at least one energy augmentation structure. Also described are various uses for the energy emitters, energy augmentation structures and energy collectors in a wide array of fields, especially in the field of solar cells and other energy conversion devices.

摘要： A stage light fixture with a split light mixing device includes a light source for generating a light beam and a light mixing device for reflecting the light. The light mixing device includes a light guide with a gradually changing cross-sectional area and a light beam homogenizer for receiving the light beam emitted from a light output surface of the light guide. The light beam homogenizer and the light guide are independent of each other, and the cross-sectional area of the light beam homogenizer is at least 1.1 times of the cross-sectional area of the light output surface. The stage light fixture further includes a holder for clamping and fixing the light guide, and a cover fastened to the end of the holder away from the light source. The cover is configured to press the light beam homogenizer tightly to closely attach to the light output surface.
