Network controlled interior lighting system

A network controlled interior lighting system, comprising:

• (1) at least one LED lamp, comprising at least an LED module, and one or more of a lens for allowing the light of the LED module to pass through, an angle adjusting device for controlling the distance between the LED module and lens, a direction adjusting device for controlling the direction of the LED lamp, and a microprocessor for central controlling, wherein the LED module comprises at least a red, a green and a blue primary color (RGB) light source;
• (2) a remote controller with wireless network connectivity, as a system control terminal;
• and
• (3) a device control unit with wire and/or wireless network connectivity, connected with the LED module, wherein the device control unit receives the control signals from the remote controller through the network, and transmits the instructions to the LED lamp to control the LED lamp to perform at least one of the following operations:
• (a) light intensity adjustment by controlling the current through the power supply circuit of the LED module;
• (b) color temperature adjustment by at least respectively controlling the drive currents of the RGB light sources;
• (c) beam angle adjustment:
• by driving the angle adjustment device to adjust the distance between the lens and LED module;
• (d) illumination direction adjustment by driving the direction adjustment device to adjust the direction of the LED lamp;
• or
• (e) light intensity control by controlling the drive current through the power supply circuit of the LED module.
