    摘要： There is provided a luminaire (1) and a collimating optics (2) for LED lights (5). The collimating optics (2) comprises a reflection collimator (3) having a first aperture (7) for allowing incoming light from a LED light (5) to enter the collimator (3) and a second aperture (9) for allowing outgoing light to exit the collimator (3). The reflection collimator (3) further has a wall (15) with a reflective inner surface for guiding the incoming light from the first aperture (7) towards the second aperture (9). A first convex lens (11) is arranged at a distance from the first aperture (7) for refracting the incoming light, and a second convex lens (13) is arranged at the second aperture (9) for refracting and collimating the outgoing light. With the disclosed collimating optics the collimating capability is improved without the size of the optics being increased.

    摘要： An LED module is provided that includes an LED circuit board having a substrate and an array of LEDs and an electrical connector mounted on the substrate. The LED module can be removed from an optical system of a luminaire by electrically uncoupling the LED circuit board from the luminaire and mechanically uncoupling the LED module from the luminaire without removing other elements of the optical system from the luminaire. A luminaire is provided that includes a controller and an optical system having an LED module. The LED module has an LED circuit board electrically coupled to the controller. The LED circuit board has a substrate and an array of LEDs mounted thereon. The LED module can be removed from the luminaire without removing other elements of the optical system by electrically uncoupling the LED circuit board from the controller and mechanically uncoupling the LED module from the luminaire.

    摘要： Embodiments of the present application provide a light and a light string for decorative lighting, and a method for controlling a display state of a light string, wherein the light comprises a cap, a light bulb, and an LED integrated lighting source. The light bulb is connected with the cap to form a sealed cavity. The LED integrated lighting source is disposed in the cavity, and both ends of the LED integrated lighting source are electrically connected to the cap via a wire. The LED integrated lighting source comprises at least one LED light string, and each LED light string comprises at least one LED light. Since each LED light has a small rated power and operating voltage, the strip-like LED integrated lighting source in the above-mentioned solution also has relatively small power and voltage, and is more energy-saving and more environmentally friendly than the prior art while satisfying the same lighting effect.
