Title:

LED LIGHT-SOURCE DEVICE FOR ILLUMINATION AND ILLUMINATOR

Document Type and Number:

Japanese Patent JP2002299694

Kind Code:

A

Abstract:

To obtain an LED light-source device for illumination in which a temperature rise is suppressed even if integration at high density is performed, and from which high optical output power and efficient as well as uniform surface emission of light are obtained, and an illuminator using the same.

This LED light-source device comprises a metal substrate 1 having a reflector function, a plurality of LED chips 2, each die-bonded on the metal substrate 1 via an electrical insulator, a transparent resin layer 5 that covers the LED chips 2 and the metal substrate 1, and fluorescent material mixed in the transparent resin layer 5.
