The luminance control unit 321 also comprises a luminance output unit 3212 for transmitting the output power to the LED light source set 20 to adjust the luminance of the LED light source set 20. Thereby, users may input luminance signals to the decorative lamp via the luminance inductor 312, so as to adjust the luminance of the decorative lamp.
  • The touchpad 32 also comprises a color control module 322 for controlling the emission color of the LED light source set 20 which includes a plurality of LED light sources with different colors, such as red, green, blue. The color control module 322 comprises a color analysis unit 3221 for selecting a LED light source with related emission color according to a color control signal, and herein, in the color analysis unit 3221, different varied signals are predetermined to be associated with light sources of different emission color; wherein the color control signals can be resistance changing signals, current changing signals, voltage changing signals or capacitance changing signals. The color control module 322 also comprises a color output unit 3222 for transmitting control signals to the LED light source with selected emission color. Thereby, users may input color signals to the decorative lamp via the color inductor 311, so as to adjust the decorative lamp's color.
  • To sum up, in the present application, with the hollow tubular routing column 40 set inside of the lamp housing 10, neither the messy routing nor the shadow of the routing column could be seen from the outside of the lamp housing, and thus the integrity of lamp housing can be maintained, the aesthetics of the decorative lamp can be improved, and a better amusement effect can be achieved.
  • What mentioned above are only preferred embodiments for the present application but not to limit the present application. Any modification, equivalent change and improvement included in the spirit and principle of the present application should be included in the scope of protection of the present application.
