Product Overview
LD-6040 is an orange-red emitting LED phosphor powder that produces stable orange-red light output when excited by 450–460 nm blue LED chips. Under blue light excitation, it emits pure orange-red light with a dominant wavelength of 594 nm and peak wavelength of 605 nm.
This product utilizes a medium-to-large particle size design with a concentrated particle size distribution, which helps improve stability during the packaging process. With a concentrated emission profile (FWHM 76.5 nm), LD-6040 helps deliver clear and stable color performance for indicator lights, signal lighting, and customized light source applications.
