Moving light with removable circuit board
View Patent ↗A moving light which has a removable part that allows upgrading and retrofitting the moving light, but yet remains balanced. The removable part can be in a balanced location, for example on the center of gravity or center of symmetry of the light. Two separate removable parts can be in different locations, one of which balances out against the other. The parts can be circuit boards, memory chips, processor chips, or digital memory devices such as a type usable in digital cameras.
1. A stage lighting system, comprising:
stage lighting components including a housing, a bulb of at least 200 W, and at least one motor that enables moving the housing, and at least one processing element, capable of carrying out a processing function, and also capable of receiving remote commands which indicate operation to be carried out by said stage lighting components; wherein said at least one processing element includes a replaceable part which is located in said housing in a location that is balanced within said housing, wherein said replaceable part includes a programmable device that can be replaced with a different programmable device; wherein said replaceable part includes first and second parts, located in different locations which balance against one another.
2. A system as in claim 1 , wherein said first and second parts have comparable geometric profiles to one another.
3. A method, comprising:
projecting light using a stage light;
remotely commanding said stage light to move between different positions of projection, including commanding the light to pan using a first motor to drive the pan, and to tilt using a second motor to drive the tilt; and retrofitting said stage light by replacing at least one processing element within said stage light, wherein said at least one processing element is at a location that is balanced relative to said stage light; wherein said replacing comprises replacing at least one chip with programmable logic thereon; wherein said replacing at said at least one chip comprises replacing at least two chips that are in balanced locations relative to one another.
4. A method, comprising:
projecting light using a stage light;
remotely commanding said stage light to move between different positions of projection, including commanding the light to pan using a first motor to drive the pan, and to tilt using a second motor to drive the tilt; and retrofitting said stage light by replacing at least one processing element within said stage light, wherein said at least one processing element is at a location that is balanced relative to said stage light; wherein said replacing comprises replacing at least one circuit board; wherein said replacing comprises replacing two circuit boards which are located in symmetrical locations relative to one another.
5. A method as in claim 4 , wherein said two circuit boards are boards that have comparable hardware profiles.
