Light Shaping Diffusers (LSDs)

1. What Is a Light Shaping Diffuser?

Light Shaping Diffusers are micro-structures pseudo randomly embedded on a substrate (such as film). When applied to a lighting structure, the LSD can manipulate light by changing the direction of its energy. This allows our Light Shaping Diffusers to clean up and shape a light beam to suit a particular purpose.


2. Where are LSDs used?

LSD are often applied in architectural lighting, can lights, decorative lighting, pool lighting, set/event lighting and wall wash lighting where the effects of LSD can be quite dramatic. LSDs are also used in illumination systems such as aircraft inspection lights; backlit systems such as cellphone and PDA displays; LCD screens and more.

3. What sizes of LED light diffusers are available?

Thin film LSDs are available in rolls, sheets or parts cut to your specifications. Standard rolls are 20” wide and 500’ long. Strip rolls are also available in your specified width.

4. Are the diffusers available for smaller applications?


Yes, Luminit Light Shaping Diffusers are available in various circular and elliptical angles in pre-cut sheet format for lower volume applications.

5. What angles are available
?

Luminit light diffusers are available in a variety of circular and elliptical angles from 1° to 100° on thin film or rigid substrates.

6. What is the transmission efficiency of Luminit diffusers?


The transmission efficiencies of Luminit LSDs are rated between 85-92% (depending on the angle). This very high-efficiency rating is due to the fact that our technology is based on diffractive microstructures. Smaller angle diffusers have the highest transmission.


7. Is the angle of diffusion and transmission wavelength dependent?

Since our microstructures are random and non-periodic, the LSD is not wavelength dependent, so it works well from 400nm to 1500nm.

8. Can Luminit LED lighting diffusers reduce hotspots with LED lights?

Yes, Luminit Light Shaping Diffusers eliminate the hotspots without a significant reduction in the amount of the light, provided that the diffuser is placed a sufficient distance from the LEDs. A rule of thumb is that the diffuser must be at least as far away from the LEDs as the LEDs are spaced apart.

9. Can Light Shaping Diffusers shape light beams?

Yes, Luminit LSD are so precise that beam shaping is possible. Our patented holographic master recording process allows a variety of circular and elliptical light patterns. Standard circular angles range from 0.5˚ to 100˚ FWHM. A wide variety of standard elliptical angles, ranging from 10˚x0.2˚ to 95˚x35˚, are available.

10. What does FWHM mean?


FWHM is an abbreviation for Full-Width Half-Maximum which is the angle of diffusion that would be seen after a collimated laser passes through the diffuser.

Actually most handy James Bond's tool...for electronic lockpicking

The Rotary Encoder LED Ring is a position indicator for rotary encoders. Traditional knobs with indicator lines do not give accurate representation of an encoder’s value since rotary encoders have no start or end point. The Rotary Encoder LED Ring has thru-hole or shaft mounting for most standard encoders and uses a Texas Instruments TLC5925 shift register to interface 16 blue LEDs to any microcontroller through SPI. A microcontroller can be programmed to output any desired sequence on the LEDs.

welcome.... energy blackouts! This is a device, that works on thermal emissions and radio waves. Its a russian manafucter, and no one else has this product. this will work on the electricity grid has a emission of "impurities" to the cable lines. Something I learned form Physics class, electricity does not go along with "impurities"
