Title:
LIGHT EMITTING ARRAY UNIT
Document Type and Number:
Japanese Patent JP3903106
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light emitting element unit which is simple to control emission and is easy to form a wiring pattern on a printed board.
SOLUTION: A first and a second light emitting element arrays 31 and 32 are formed on inner faces of a first and a second array substrates 21 and 22 which are set opposite to each other. Each of light emitting element arrays 31 and 32 has LED chips 33 arranged in a direction orthogonal to a film feed direction. LED chips 33 of one light emitting element array are shifted by an amount of one chip to LED chips 33 of the other light emitting element array in the arrangement direction. An optical path of light from each LED chip 33 is folded by prisms 25 and 26 to be aligned and emitted in an array.
