Abstract
A sound adapting luminaire produces an amount of cooling output that depends on the ambient sound. When the ambient sound is high, the lamp is cooled more aggressively, since more fan noise is acceptable.
Claims18
A lighting device, comprising:
- a lamp that emits light;
- a housing, holding at least said lamp;
- an electrically controllable variable fan, coupled to said housing;
- a controller, which receives a signal that includes first information to control said lamp and second information that indicates an expected amount of ambient sound at least at one time, said controller which is programmed to determine a first amount of sound in said area of said housing based on said second information, and to control said fan based on said first amount of sound in an area of said housing between a first amount of output of said fan which occurs when the first amount of sound in the area of said housing is expected to be lower, and a second amount of output of said fan, which produces more air output from said fan and more noise from said fan, which occurs when the amount of sound in the area of said housing is expected to be higher.

A lighting device, comprising:
- a housing, holding a number of heat-producing elements, including at least a socket for a lamp, wherein when said lamp is inserted into said socket, said lamp emits light;
- an electrically controllable variable fan, coupled to said housing, and operable to cool an inside of said housing;
- a controller, that receives a signal from a controller indicative of an expected amount of sound at a first time, and which is programmed to first detect an overtemperature condition in the housing, in which a temperature in the housing is higher than a specified amount, and operates a level of the fan at a specified cooling level independent of the expected amount of sound responsive to first detecting said overtemperature, and also programmed to second, during a time when not detecting said overtemperature condition in the housing, use said signal indicative of the expected amount of sound to control an amount of output of said fan.
A method, comprising:
- operating a remotely controllable luminaire to produce a light output from a lamp within a housing;
- using a fan for cooling an inside of said housing;
- receiving a signal indicative of an expected amount of sound in an area outside of said housing that has been staged in advance;
- controlling said fan based on said expected amount of sound in said area between a first amount of output of said fan which occurs when the expected amount of sound is lower, and a second amount of output of said fan, which produces more air output from said fan and more noise from said fan, which occurs when the expected amount of sound in the area is higher.
