摘要
Multiple LEDs (11) are arranged so as to emit light in the same direction. Multiple optical systems (12) are provided corresponding to each LED (11) to convert the numerical aperture of the light emitted by the LEDs (11). Defining L as the representative size of the light-emitting surface of the LEDs (11), Iled as the interval between neighboring LEDs (11), Do as the representative size of the optical systems (12), Io as the interval between neighboring optical systems (12), and NAout as the numerical aperture of the light emitted from the device, it holds that 0.8L/NAout ≤ Do ≤ 1.1L/NAout, Io ≤ Iled, and Io ≤ Do.
