description An edge type light module having a light emitting surface including at least one middle light emitting region and at least one edge light emitting region is provided. The light module includes a first edge type light emitting device emitting light from the middle light emitting region and a second edge type light emitting device stacked on the first edge type light emitting device and emitting light from the edge light emitting region. If the middle light emitting region is a lighting region having brightness L1, the edge light emitting region adjacent to the lighting region is a light leakage region. The light leakage region has predetermined brightness L2, and compensation brightness L2' of the light leakage region satisfies L2'=L2-(L1xk1xR1), wherein 0 ≤ k1 ≤ 1, and 20% ≤ R1 ≤ 60%. If the edge light emitting region is a lighting region having brightness L3, the middle light emitting region adjacent to the lighting region is a light leakage region. The light leakage region has predetermined brightness L4, a
