LIGHT DETECTING AND EMITTING ELEMENT MODULE

摘要

PROBLEM TO BE SOLVED: To provide a light detecting and emitting element module which enables the high-density mounting of chips and allows defective chips to be easily replaced. SOLUTION: A LED module 10 has LED chips 13 arranged in an array with mutual spacings on the surface of a semiconductor substrate 11, each chip having a plurality of light emitting diodes LED 15. The chips 13 include alternately arranged high chips 13a and low chips 13b thinner than the high chips 13a. The high chip 13a has slant faces 17 adjacent to and overhanging the low chips 13b in profile of the chip array.
