Light Emitting Converters (LECs)

Light Beam’s patented LEC material is a unique polymer-based substance which is able to wavelength shift through a photoptic process of absorption and emission in the cross-linked plastic material. The shorter wavelengths of light from the solid state emitting source are completely absorbed, or in part if so desired, and re-emitted as light at longer wavelengths.

The LEC material has been used in many different custom applications, and Light Beam is now working on a production process to make the material available in rods, sheets, injection molded or cast shapes. The material can also be machined.

LEC material can be tuned to specific wavelengths in the color spectrum and the concentrations can be tailored to exact specifications. Please refer to the press releases for other specifics on this material.

Possible Applications:

• Laser Rods
• Binning-independent LED Lenses
• Corporate Signage
• Light Pipes
• Instrument Panel Indicators
• Custom Color (designer) LEDs
• Any application where uniformity and vividness of color are important

Light Beam has the technical expertise to custom configure our LEC material to satisfy your specific application. Call us today at (541) 228-3650 for more information.

Designer LED-C™ Unveiled: Create Any Color LED In the Visual Light Spectrum

Light Beam Industries has developed a new Solid State Designer LED-C™ (Light Emitting Diode Converter) System. This new material gives the ability to create a system in which a monochromatic or white LED is used and then the solid state lighting source is embedded in the LED-C™ material, creating a monolithic component, which then converts all of the energy from the LED and re-emits at the color chosen.

LED-C™ material generates light by wavelength upshifting through a photoptic process of absorption and emission in the cross-linked polymeric materials. The shorter wavelengths of the light from the solid state emitting source are absorbed completely, or partially, if preferred, and then re-emitted as light at longer wavelengths which are determined by the color of the material chosen.

LED-C™ uses fluorescent dyes in a polymeric matrix and solid state light source to generate multicolored light as well as true white light from 3000K to 6000K. This patented material also gives you the ability to create one, two and even three or more colors generated simultaneously from a single solid state monochromatic color.

The new designer LED-C™ can, through wavelength manipulation, produce colors and hues not available in standard LEDs. LED-C™ can produce wavelengths from 440nm to 660nm with current drive levels from 5mA to 400mA and has a life expectancy of up to 100,000 hours. This means that there are effectively no longer color gaps in the visual spectrum where LEDs are concerned.

The future is bright and LED-C™ Designer LEDs create tunable and consistent colors for a vast range of applications, many of which were previously unobtainable.

Laser Material

Dye laser technology - The solid state dye laser rods are a unique high temperature, cross-linked, polymeric solid state dye laser material, which are characterized by a high degree of purity, overall production conformity between batches, and virtual freedom from bubbles and voids. Solid state rods can be produced in long lengths (up to 50'), and with diameters ranging from 1/8" to 1".

The LEC materials produce intense fluorescence at targeted peak wavelengths. By using our LEC fluorescent materials you can create "designer LEDs" as it allows you to tune the colors of the LEDs.

Our Light Emitting Converters, or LECs, are uniquely designed to absorb incoming light waves and re-emit the light at their own specific wavelength. This material can be used as Solid State Laser Rods. Our proprietary material can be used to change existing wavelengths of lasers. You can simply shoot the existing laser beam into our material and it will be absorbed and re-emitted at the new wavelength.

Primary Application: the ability to manipulate wavelengths in dye lasers. For example, a typical dye laser will produce a green laser, which is a particular wavelength. If a different wavelength is desired, the only way to get it from the same laser machine is to use the dye rods. These dye rods are used for a certain number of pulses and then replaced. However, it is a substantial savings over purchasing an entirely new machine.
