ABOUT PRINCETON TEC 

 
At Princeton Tec, we've been pioneering new technologies and building lights for more than three decades. And yes, you could say it's been quite a ride. In our pursuit to be the world's best, we've travelled the earth by ocean, by air, by bike and by foot. We've consulted great athletes, scaled mountains, traversed the poles, touched the ocean floors and rolled two wheels on every continent. We are constantly inspired by what our ever evolving environments have to offer and the human spirit that challenges us to tackle them. This spirit, our spirit, motivates us to push technology and design, so that we can ensure that you have, not only the best lighting solutions, but solutions where technology is applied and the performance makes sense for how you use them. 
 UNDERWATER KINETICS TECHNOLOGY - HOW IT WORKS - eLED
The LED is the most significant innovation in portable lighting since the advent of the incandescent lamp. It is more efficient, less fragile, runs cooler, and has a 50-100 times improvement in life expectancy. The quality of light is quite different from that of an incandescent lamp. It appears much whiter and shines farther underwater. Despite all of the positives there are also some challenges. Red and purple objects do not appear as vibrant under white LED light. Brightness decreases slightly as the LED heats up. Power is limited to a few watts per LED. Large arrays of LEDs must be clustered to reach the illumination of a high wattage incandescent lamp. Although decreasing, the cost of an LED is still high, and can only be justified by the knowledge it may never need to be replaced
Light Wavelength
 
UK LED Design Features
- Constant Brightness
The unique electrical properties of the LED make it possible to attach it to an electronic circuit which controls power from the batteries in a flashlight in such a way brightness and colour of the beam remain constant as the batteries drain.

Contrast this to a conventional flashlight with an incandescent bulb. With fresh batteries the light is extremely bright. As the batteries are consumed the light grows dim and the colour turns more yellow. This feature is represented by the 'e' used in naming UKeLED lights.

Another unique feature of LEDs is that they continue to give light when there is very little power left in the batteries. The benefit is that even though the batteries are considered dead in any other type of flashlight, theLED continues to give light for hours or even days after the high brightness mode is past. For emergency situations this could make the difference.
Brightness vs Time
Heat Dissipation
For any light which uses LEDs it is extremely important to keep the LED from getting too hot (less than 130oC, 266oF.) Heat shortens the life of the LED and reduces the brightness. At UK we have developed circuitry which monitors the temperature of the LED and cuts back power when it gets too hot. We have also developed specialized metal heat sinks which carry heat away from the LED and into the surroundings. Underwater this affect allows our lights to burn even brighter as the water acts as a coolant for the LED.
 
Multiple LEDs
Unlike incandescent lamps, the maximum power which a LED can handle is about 5 watts. The only way for a LED flashlight to be brighter is to use more than one LED.
At UK we work to find innovative ways to cluster several LEDs in such a way as to provide a uniform beam of light which appears like it was made from central lamp and to remove the additional heat in order to protect the LEDs.
Improved Efficiency
As LEDs are manufactured, some are brighter than others. They are then sorted into bins based on brightness. Brighter LEDs which are also more efficient at converting energy into light are more rare and expensive to light manufacturers such as UK. When selecting LEDs to include in our lights we work with the suppliers to get the brightest we can at a price which will meet the budget of our customers. In addition innovative means are used to remove heat from the LED for improved brightness and efficiency.
What is an LED?
LED stands for Light Emiting Diode. It is a semiconductor device which converts electrical energy directly into light. Compare this to the incandescent lamp which converts energy into light by heating a thin wire filament until it glows and gives off light.
LEDs are made from a semiconductor material that has impurities called "dopants" that are added to the crystal. Two types of dopants are added to create "N" and "P" regions. "N" regions are parts of the crystal that are electron rich (free electrons) and "P" regions that are deficient in electrons (free holes). When the "P" region is connected to a positive voltage and the "N" region is connected to a negative voltage a current flows. When an excited electron from the "N" region meets with a hole from the "P" region, they combine where the two regions meet. This liberates energy of a discrete amount (the sum of electron and hole energy) in the form of light of a particular color.
White LEDs are formed by covering a blue LED with a yellow phosphor. This phosphor converts the blue light to a range of colors in the yellow part of the spectrum. This combination of blue and yellow light gives the appearance of white. Compare the color spectrums of white LEDs and incandescent lights.
Up to now, LEDs were not very efficient. Today, they are approaching the efficiencies of our best incandescent bulbs. In the next few years they are predicted to surpass most other forms of illumination in terms of light output for a given amount of power. LEDs are mechanically robust and last substantially longer than incandescents.
