Abstract
A lighting apparatus includes an optical member with a diffractive optical element. The optical member is directly fixed on a substrate with plural lighting chips. When the lighting apparatus is applied to a laser diode module, the height and volume of the overall laser diode module are reduced. Consequently, the laser diode module is suitably applied to a small-size device.
