Abstract

A lighting apparatus includes a rectifier, a 0-10V dimmer converter, a power circuit and a light source. The rectifier for receives an AC power from an AC input to generate a DC current. The TRIAC wall switch is selectively coupled to the AC input. The TRIAC wall switch is operated by a user with an first manual operation to suppress a portion of the AC power from the AC input corresponding to the first manual operation. The 0-10V dimmer converter is selectively coupled to a 0-10V dimmer. The 0-10V dimmer converts a dimmer voltage of the 0-10V dimmer to a dimmer signal corresponding to a second manual operation of the user. The power circuit is coupled to the 0-10V dimmer converter and the rectifier to convert the DC current to a set of driving current. The light source includes multiple LED modules.

Dependent claims

A lighting apparatus, comprising:

a rectifier for receiving an AC power from an AC input to generate a DC current;
a 0-10V dimmer converter for selectively coupled to a 0-10V dimmer, wherein the 0-10V dimmer converter converts a dimmer voltage of the 0-10V dimmer to a dimmer signal corresponding to a second manual operation of the user;
a power circuit for coupling to the 0-10V dimmer converter and the rectifier to convert the DC current to a set of driving current;
and
a light source comprising multiple LED modules, wherein the light source receives the set of driving current to emit a light corresponding to the second manual operation, wherein the power circuit lowers a color temperature automatically when lowering a light intensity of the light source, wherein the power circuit detects whether the 0-10V dimmer is coupled to determine the set of driving current.
