Embodiment Construction

[0014] A preferred embodiment is shown in the drawings, like reference numerals being used to designate like and corresponding parts of the various drawings.

[0015] figure 1 A schematic diagram of a luminaire system 10 according to the present disclosure is presented. Luminaire system 10 includes a plurality of luminaires 12 according to the present disclosure. The luminaires 12 each include one or more of a color changing system, a light modulating device, and a pan and / or tilt system to control the orientation of the head of the luminaire 12, as well as an on-board light source. as reference figure 2 Described in more detail, the mechanical drive system used to control the parameters of the luminaire 12 includes a motor or other suitable actuator coupled to a control system configured to control the motor or other actuator.

[0016] In addition to being connected to the mains directly or through the power distribution system, the control system of each luminaire 12 is ...

Abstract

A luminaire has a light-emitting diode (LED) light source, a light sensor, and a control system. The control system receives a measure command for measuring the current intensity of the LED light source. The control system measures the intensity using the light sensor, stores current intensity data in non-volatile memory, obtains the LED light source's previous intensity, selects an indicator color representing how much the current intensity is reduced from the previous intensity, and causes the luminaire to emit a light beam having the indicator color. The control system also receives an adjustment command for reducing the LED light source to a total intensity reduction amount. The control system obtains the LED light source's current reduction amount, determines whether the total intensity reduction amount is more than the current reduction amount, and, if so, causes the LED light source to emit a reduced intensity light beam.

Description

technical field [0001] The present disclosure relates generally to automated luminaires, and more particularly to methods for matching light output from light emitting diode (LED) luminaires. Background technique [0002] Luminaires with automatic and remotely controllable functions, known as automatic luminaires, are well known in the entertainment and architectural lighting markets. Such products are commonly used in theaters, television studios, concerts, theme parks, nightclubs, and other venues. Typical automated luminaires provide control from a remote location of the luminaire's pan and tilt functions, allowing the operator to control the direction the luminaire is pointed, and thus control the position of the beam of light on stage or in the studio. Typically, this position control is accomplished by controlling the position of the luminaire on two orthogonal axes of rotation, commonly referred to as pan and tilt. Many automated luminaires additionally or alternati...
