Abstract

An all-color light control switch that is used by an operator for free adjustment or control of a light emitting diode lamp set; using multiple sets of commands for light variations stored in a non-volatile memory unit in a microprocessor on the circuit board, and by switching a rotational encoder and a coaxial press knob, the operator can control the brightness and different colors of light variations of an LED lamp; special designed light guide member guides and mixes multiple-color LED light sources on the circuit and displays them on a panel.

Claims

1. A all-color light control switch, comprising a circuit board installed in a switch hardware unit, serving as a control center, the circuit board having a microprocessor, a set of color light drivers, a rotational encoder having a co-axial switch, and multiple sets of multi-colored LED sets and serial signal interfaces;

wherein the microprocessor translates rotation of the rotational encoder and press and release operation of the coaxial switch into control of color light using a non-volatile memory unit to store an operational status for controlling brightness and color variations of a far-end LED lamp set, or future operation.

2. The all-color light control switch of claim 1, wherein the switch hardware unit comprises a base plate, a casing, a circuit board, a light guide plate and a coaxial press knob;

the base plate being combined to the casing as one unit by fastening a snap hole on the base plate to a snap hook on the casing, the base plate having a hollow and a screw hole for fixing the base plate on a wall, on two sides of the hollow being screw thread units, on the casing and matching the hollow being a through hole, on a periphery of the through hole being a ring-shaped recessed groove membrane, the circuit board being screwed onto the screw thread units on the base plate by running a screw bolt through the screw hole, to fix the circuit board onto the base plate, the microprocessor on the circuit board being connected with the coaxial switch for adjusting brightness of a light source from the multiple sets of multiple-color LED sets distributed on the coaxial switch, at a center of the light guide plate being a through hole, the coaxial switch installed on the circuit board being pulled into a through hole through the hollow and the casing and a through hole on the light guide plate, at an end of the coaxial switch and on an outside edge of the casing being inserted a coaxial press knob, the light guide plate being positioned on the ring-shaped recessed groove membrane on the casing, thereby an operator is free to directly rotate the coaxial press knob and by switching the coaxial switch to adjust and control the brightness of the far-end LED lamp set, or by pressing up, down, left or right of the coaxial press knob to control color variations for the far-end LED lamp set.

3. The all-color light control switch of claim 1, wherein the multiple sets of multiple-color LED sets are either one of the following, a combination of multiple sets in one single color and a combination of multiple sets in multiple colors.

4. The all-color light control switch of claim 1, wherein the rotational encoder of the coaxial press switch includes a set of light guide plates, to guide light sources from the multiple sets of multiple-color LED'"'"'s on the circuit board to a light guide plate to increase flexibility of panel design.

5. The light control switch of claim 1 includes a set of serial signal output interfaces that is capable of transmitting signals of light variations through a specific transmission protocol to other control units, in addition to an all-color light driver circuit.
