Abstract:
1. A movable lamp, comprising: a base that attaches to a supporting truss, said base having a processor; a moving light head that includes a light and moves said light relative to the base based on a control that is received by said processor from a remote controller; an electronic brake, which holds said moving light head relative to said base when a braking effect is engaged, said electronic brake being controlled into a braking effect state, and staying in said braking effect state, to prevent movement between said base and said moving light head, and said electronic brake removing said braking effect to allow free movement between said moving light head and said base, only by receiving a command in said processor from said remote controller, and not automatically removing said braking effect without receiving said command from said remote controller, wherein said brake requires a first level of current to maintain said brake in an off position, and requires a second level of current higher than said first level of current to remove said braking effect and put said brake into said off position.
