Root cause of why LEDs changes colour, turn yellow over time

Having a problem with spoilt LEDs, LEDs turning yellow or having inconsistent LED light colours within months?


Through working with Nichia Corporation (World no.1 LED chipset manufacturer) from Japan, we came across one of their publication discussing the issue above. The article focuses on lumens maintenance and colour maintenance

In summary and simplicity, some reasons mentioned are;
1. LEDs have plastic components that contain Benzene ring that degrade with photon energy - That makes the white portion of LED packages turn yellow.
2. Heat from the LEDs in operation.

Solutions;
1. Use thermoset composite and inorganic materials for better reflectivity and stronger structural stability.

Simplistic, elegant LED lighting for pedestrian walkways

HessAmerica, a subsidiary of Hess GmbH Licht+Form of Germany, has announced the Parco family of pole-mount, bollard, and wall-mount fixtures for pedestrian-centric applications. The striking designs are in unique form factors and target applications such as sentry plazas, pathways, and outdoor gathering spots in commercial, hospitality, and high-end residential applications.

The pole-mount luminaire is the centerpiece of the Parco line and presents a quite different approach to pedestrian-area lighting as you can see in the nearby photo. The pole features an arched shape with the light engine mounted at the top of the pole pointed directly at the ground. The novel design is indeed dark-sky compliant, producing no up or spill light.
Lighting designers/specifiers can order the Parco fixtures with either LED or metal-halide (MH) sources. Moreover, the company offers models in 10-, 12-, and 14-ft pole heights.
LED versions come in 48W or 68W flavors with both generating an IES type III rectangular beam. The options include 3000K models delivering 3200 or 4800 lm, and 4000K models delivering 3360 or 5040 lm. CRI is 80. The MH versions include 39W standard and 70W ceramic MH products. The company hasn't published detailed performance specs for the MH versions.

Details are also still to come on the bollard and wall-mount products in the Parco line, although you can see the bollard in one of the nearby photos. While the bollard uses a typical straight post, the rectangular cross-section matches the look of the pole fixtures. The company said the wall-mount fixtures will also deliver a consistent look. All of the products will be offered in matte-silver gray metallic, dark gray, and graphite gray.
