SPECTRA OF PHOSPHOR PURPLE LEDS


This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD LEDS (driven at 20mA to 60mA; with the exception of the LED in the Motion-Sensing Spotlight):

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.

PHOSPHOR PURPLE LEDS:


Spectrographic analysis of the purple LEDs in the 50xLED Battery Operated Mini Lights.
The purple color is a bit sickly; it reminds me slightly of the phosphor purple LEDs in the Purple Mini LED Light Set which (to me anyway) were extremely bluish.



Spectrographic analysis of the purple LEDs in the 50xLED Battery Operated Sound Synch Wire Lights.
The purple color is a bit sickly; it reminds me of the phosphor purple LEDs in the Purple Mini LED Light Set which (to me anyway) were extremely bluish.


Spectrographic analysis of the LEDs in the Purple Mini LED Light Set.



Spectrographic analysis of the LEDs in the 20 LED Micro 8-Function Phosphor Purple Halloween Lights.


Spectrographic analysis of the LEDs in the 20 LED Micro 8-Function Phosphor Purple Halloween Lights; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint native emission peak wavelength, which is 450.470nm.


Spectrographic analysis of the LEDs in the 20 LED Micro 8-Function Phosphor Purple Halloween Lights; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint phosphor emission peak wavelength, which is 633.310nm.

Spectrographic analysis of an ETG-5AX420-15 phosphor purple LED; newer spectrometer software settings used.



Spectrographic analysis of an ETG # ETG-5AX420-15 phosphor purple LED.



Spectrographic analysis of a Lumex #SSL-LX5093PC phosphor purple LED, driven at ~1.9mA.



Spectrographic analysis of a Lumex #SSL-LX5093VC phosphor purple LED, driven at 19.28mA.



Spectrographic analysis of an ETG 5AX440-45-D water-clear phosphor purple LED.



Spectrographic analysis of the phosphor purple LED in the Rainbow In My Room.



Spectrographic analysis of the purple LEDs in the LED ''SIGNS'' Sign.



Spectrographic analysis of the fuchsia LED in the LED 6-Light Necklace.
This LED is flashing, not steady, so I was unable to obtain a full-height spectrum of it.



Spectrographic analysis of a phosphor purple LED (ETG-5AX420-15).



Stable phosphor-type purple LED.










Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light 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.
