    • A pipe elevator handle clamp for securing to pipe elevator handles to hold them in place comprises a top clamp section hingedly connected at one end to a bottom clamp section and releasably secured to each the bottom clamp section at the other end. The top clamp section and bottom clamp section define elongated structures that, when positioned together in the closed position, include two receiving holes for receiving and securing elevator handles. The hinge connection is defined by a hinge aperture that passes through both the top clamp section and bottom clamp section and has a hinge pin for providing the fixed axis of rotation therein. The device is secured around bull horns by hinging the top clamp section and bottom clamp section into the closed position and inserting a clamp fastener into a fastener channel that extends through the top clamp section into the bottom clamp section.

    • A system provides white light having a selectable spectral characteristic (e.g. a selectable color temperature and intensity) using a combination of sources (e.g. LEDs) emitting light of four, five, or six different characteristics, for example, one or more white LEDs, and one or more LEDs of each of three primary colors plus cyan and royal blue. A microcontroller can maintain a desired spectral characteristic, e.g. for white light at a selected point on or within a desired range of the black body curve. Further, the microcontroller provides tunability of the spectral characteristic and intensity of the white luminaire. One channel driver drives the one or more first color LEDs (white in our example) as well as the one or more second color LEDs which are connected in series to the first channel driver. The other light sources are each driven by separate drivers on separate channels.
    • 系统使用发射四个,五个或六个不同特征的光(例如一个或多个白色LED)的源(例如LED)的组合来提供具有可选择的光谱特性(例如,可选色温和强度)的白光,以及 三原色中的一个或多个LED加上青色和皇家蓝色。 微控制器可以保持期望的频谱特性,例如。 对于黑体曲线的期望范围上或之内的选定点处的白光。 此外,微控制器提供白光灯的光谱特性和强度的可调性。 单通道驱动器驱动一个或多个第一颜色LED(在我们的示例中为白色)以及与第一通道驱动器串联连接的一个或多个第二颜色LED。 其他光源分别由单独的通道上的独立驱动器驱动。

    • A lighting system having at least three light sources receives an input relating to color coordinates of a target point representing a desired color characteristic for a combined output from the light sources. The system defines first-pass endpoints corresponding to color characteristics of the light sources when operated at respective maximum intensities. The system determines first-pass amounts of respective maximum intensity contributions from the light sources to achieve light of the target point. When dimming the light to an intensity proportion, the system determines first-pass driver settings from the first-pass amounts and the intensity proportion. The system defines second-pass endpoints corresponding to color characteristics of the light sources when operated at the determined first-pass driver settings. The system determines, from the second-pass endpoints, second-pass amounts of respective reduced intensity contributions from the light sources; and the system determines second-pass driver settings for the second-pass amounts.
