Nichia has announced the release of a new line of products designed to enable different light distribution than conventional LEDs. The product line is based on new LED emitters called Cube Direct Mountable Chip. See photo above. It is a chip scale packaging (CSP) LED, which in itself increases the amount of light emitted through the sides of the package. Nichia takes this CSP tendency further and adds an additional diffusion layer above the phosphor layer to create even greater side emissions and likely even some back light. The result is ultra-wide angle emissions that have a few benefits:
- Ultra-wide emissions creates more diffuse light. A ceiling fixture emitting more diffuse light will better light the upper walls and even the ceiling, compared to a more directional emitter directing a large percentage of light down to the floor.
- The more diffuse light reduces hot spots and dark spots through a diffuser. This can enable thinner, lower-profile, more lightweight luminaires without hot spots, dark spots, nor pixilation.
- More diffuse emissions can reduce glare compared with more directional emitters.
In addition to the new CSP LED emitters, Nichia has released a module built with these emitters, that it calls the Nichia Light Cluster Type L. See the first image below. The benefits of the module are essentially the same as the Cube Direct Mountable Chip, just fully integrated into a module, for more rapid luminaire design.
These products also have the same advantages for LED backlit signs, which can be made thinner and lighter, without pixilation.
