Lighting apparatus

The application discloses lighting apparatus includes: the board, have the resolution chart like, through a multichannel output test signal, test signal conversion module will a test signal converts data signal into, passageway order is from adaptation module, according to data signal judges first passageway order, and is right first passageway is establish new mapping in proper order and is obtained the second channel order to export the 2nd corresponding test signal, little control module has the resolution chart like the gray scale signal of partial pixel, control the passageway order is judged from adaptation module first passageway order and basis first passageway sequential control the passageway order obtains from adaptation module the second channel order, signal processing moduleexports the 3rd test signal and synchronization signal, second channel order with the range phase -match of part pixel. Eliminated simplely high -efficient that lighting apparatus causes because of the passageway of the insid
