【課題】小型、高輝度及び低消費電力であり、且つ配光制御が可能な発光装置を提供する。【解決手段】発光素子がm行n列(nは1以上の整数、mは3以上の整数)のマトリクス状に配列されている発光パネル10と、少なくとも1つの行を隔てて配列されている一対の行を含むK行(Kは2以上m未満の整数)分の各行に属する発光素子を駆動周期毎に、時系列的にK分割して順次、発光駆動する第1のドライバと、上記した少なくとも1つの行に属する発光素子を駆動周期毎に発光駆動する第2のドライバと、を有する。【選択図】図1
A lightening apparatus includes light-emitting elements (P 1,1 , P 1,2, ···) arranged in a matrix. One of the light-emitting elements (P 2,1, P 2,2, ···) is located at each intersection between at least two first reference voltage lines (S2, S5) and "m" first drive voltage lines (Y1, Y2, ···). A first reference voltage driver (3) time-divisionally switches the first reference voltage lines (S2, S5). A first drive voltage driver (6) supplies first luminous drive voltages (B1, B2, ···; E1, E2, ···) to the first drive voltage lines (Y1, Y2, ···). One of the light-emitting elements (P 1,1, P 1,2, ···, P 3,1 ,P 3,2 ,···; P 4,1, P 4,2, ···) is located at each intersection between at least one second reference voltage line (S1, S3; S4) and "m" second drive voltage lines (X1, X2, ···; Z1, Z2, ···). A second reference voltage driver (2, 4) switches the second reference voltage line (S1, S3; S4). A second drive voltage driver (5, 7) supplies second luminous drive voltages (A1, A2, ···, C1, C2, ···; D1, D2, ···) to the second drive voltage lines (X1, X2, ···; Z1, Z2, ···).
