Abstract: A lighting apparatus includes a first light source, a second light source and a driver. The first light source has multiple first LED modules. The second light source has multiple second LED modules. The driver controls the first light source and the second light source to generate an output light of a required mixed color temperature. The driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature. The driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature. The first subset is not equal to the third subset. The second subset is not equal to the fourth subset.

Abstract: A lighting apparatus includes a first LED module, a second LED module, a third LED module, and a driver. The first LED module emits a blue light with a first peak wavelength between 440-470 nm. The second LED module emits a green light with a second peak wavelength between 510-550 nm, a second spectral bandwidth larger than 50 nm and a second color purity larger than 50%. The third LED module emits a red light with a third peak wavelength between 600-650 nm, a third spectral bandwidth larger than 60 nm and a third color purity larger than 80%. The driver adjusts a light ratio among the first blue light, the green light and the red light.

Abstract: A lighting apparatus includes a first light source, a second light source, a third light source, a driver, a first controller, a second controller and a main controller. The first light source emits a first light with a first color temperature. The second light source emits a second light with a second color temperature. The third light source emits a third light with a third color temperature. The driver generates a first driving current to the first light source, generates a second driving current to the second light source, and generates a third driving current to the third light source.

Abstract: The lighting apparatus includes a first LED module, a second LED module and a third LED module. The first LED module emits a first light of a first color temperature. The second LED module emits a second light of a second color temperature. The third LED module emits a third light of a third color temperature. The driver is used for generating a first driving power, a second driving power and a third driving power respectively supplying to the first LED module, the second LED module and the third LED module. The controller is for determining a power ratio corresponding to a mixed light with a target color temperature mixed by the first light, the second light and the third light. The mixed lights of different target color temperatures have chroma coordinates within a predetermined chroma range.

Abstract: An assembly light apparatus has a station bracket, a fixed light module, and a portable light module. The station bracket has a fixed holder, a detachable holder and a pose adjuster structure. The fixed light module is fixed on the fixed holder. The portable light module is selectively attached on the detachable holder. The pose adjuster structure is operated to rotate to change an angle and a position of the fixed holder and the detachable holder with respect to the station bracket.
