NARROWBAND SPECTRA OF LOW-POWERED PHOSPHOR ORANGE LEDS

This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD phosphor orange LEDS (driven at 20mA to 60mA):

Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.
As of 09-19-09, I no longer have the PC2000-ISA; it was sold to prevent an eviction.

NARROWBAND SPECTRA OF PHOSPHOR ORANGE LEDS:


Spectrographic analysis of the orange LEDs in the 50xLED Battery Operated Mini Lights; spectrometer's response narrowed to a band between 600nm and 640nm to pinpoint the phosphor peak emission wavelength, which is 615.690nm.


Spectrographic analysis of the orange LEDs in the 50xLED Battery Operated Mini Lights; spectrometer's response narrowed to a band between 465nm and 485nm to pinpoint the peak native emission wavelength, which is 475.430nm.

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at 50boo.txt



Spectrographic analysis of the LEDs in the 20 LED Micro 8-Function Halloween Lights; spectrometer's response narrowed to a band between 580nm and 630nm to pinpoint phosphor's peak emission wavelength, which is 616.030nm.

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at 20hall.txt



Spectrographic analysis of the LEDs in the 20 LED Micro 8-Function Halloween Lights; spectrometer's input deliberately overloaded to show the blue emission.
This (plus an examination of the LED's die area and the unexpectedly broadband emission) leads me to believe that these LEDs are actually PHOSPHOR ORANGE LEDs!!!
The native emission appears to peak at 474.730nm.

Do you manufacture or sell an LED flashlight, task light, utility light, module of some kind, or small-frame lasers? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light or laser did? If you have a sample available for this type of real-world, real-time testing, please contact me at bdf1111@yahoo.com.

Please visit this web page for contact information.

Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
