SPECTRA OF LOW-POWERED VIOLET LEDS (3)


This web page will be for nothing but spectra of 10mm, 8mm, 5mm, 3mm, and SMD 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.



VIOLET LEDs

Spectrographic analysis
Spectrographic analysis of the LED in the NUV "Bullet" Light.


Spectrographic analysis
Spectrographic analysis of the LED in the NUV "Bullet" Light; spectrometer's response narrowed to a range between 380nm and 440nm to pinpoint peak wavelength.


Spectrographic analysis
Spectrographic analysis of an unknown-type NUV LED.


Spectrographic analysis
Spectrographic analysis of the American Technical Services LED Modules NUV LED module; newer spectrometer & software used.


Spectrographic analysis
Spectrographic analysis of the NUV LED in the Secret Pen.


Spectrographic analysis
Spectrographic analysis of a Roithner Lasertechnik RLT420-3-30 blue-violet 5mm LED; newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the violet version of the InReTECH 2AA kits; newer spectrometer software & settings used.


Spectrographic analysis
Repeated spectrographic analysis of the LEDs in the Infinity Optics Clock; LEDs are in an advanced state of decay.
Repeated in order to show lack of a broadband "hump" in the yellow often seen in degraded UV and NUV LEDs.

Spectrographic analysis
Spectrographic analysis of the NUV LEDs in the White/UV LED/Laser Torch (2); newer spectrometer software & settings used.


Spectrographic analysis
Spectrographic analysis of the violet LED in a computer case accessory.













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 ledmuseum@gmail.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.
