摘要： A lighting apparatus includes an external controller, a first LED module, a second LED module, a rectifier, a power switch, a manual switch, a light housing and an allocation module. The external controller converts an external signal of an external wall switch to a light intensity signal. The external controller is coupled to the external wall switch. The wall switch is a continuous switch for a user to select a continuous value from a range. The first LED module and the second LED module emit lights of different color temperatures. The rectifier for converts an AC power to a DC power. The power switch is coupled to the rectifier for generating a driving current corresponding to the light intensity signal. The manual switch selects a color temperature setting.

摘要： A lighting apparatus includes a lens module, a light source plate, a first set of LED modules ad a second set of LED modules, and a driver. The first set of LED modules are located at first positions of the light source plate. The second set of LED modules are located at second positions of the light source plate. The driver controls the first set of LED modules and the second set of LED modules for generating a first output light pattern and a second output light pattern. The first light pattern and the second light pattern are mixed to generate one of multiple projected shapes on a projected surface controlled by the driver.
