Nichia HPS 1800K White LED Technology: Revolutionizing warm & nostalgic outdoor lighting

Nichia HPS White LED Technology: Revolutionizing warm & nostalgic outdoor lighting

Nichia, the world's largest LED manufacturer and inventor of high-brightness blue and white LEDs, introduces HPS color LEDs—an innovative lighting solution that accurately replicates the warm, amber glow of High-Pressure Sodium (HPS) lamps, which are commonly used for road and outdoor lighting worldwide. As a true alternative to mercury-containing HPS lamps, HPS color LEDs support the transition to a mercury-free society and contribute to carbon neutrality.

Addressing Challenges in LED Adoption

High-Pressure Sodium (HPS) lamps typically have a color temperature around 1800 Kelvin (K). This color temperature gives HPS lamps their characteristic warm, amber-yellow light, which is commonly used for street lighting and outdoor applications. In contrast, conventional LED outdoor lighting has a bluish-white light of 5000K or more. Further more, with conventional warm white LEDs, the amber-yellow, 1800K light, is not possible to reproduce.

While the adoption of LEDs for street and outdoor lighting has surged in the past decade due to their high-efficiency and long lifespan, this impossibility to reproduce the light of HPS lamps has created still challenges in residential and urban areas. Concerns about the different light of conventional LEDs altering the familiar landscape and atmosphere have hindered widespread adoption. In some instances, streetlights that were converted to LEDs have reverted to HPS due to residents' demands. Additionally, issues related to light pollution, such as sleep disturbances from excessive glare, obscured visibility of stars, and adverse effects on the ecosystem, have been noted.

Advantages of Nichia's HPS Color LEDs

Nichia's HPS color LEDs offer a significant improvement by maintaining the warm, familiar emission color of HPS lamps, with a typical wavelength of 1800K. These LEDs preserve the landscape and atmosphere while reducing the light pollution associated with higher color temperature LEDs. This makes them an ideal solution for smoothly transitioning to LED technology in areas where the switch has been resisted due to concerns about changing the visual environment.

Facilitating the Transition to LED

By offering the same warm emission color as HPS lamps, Nichia's HPS color LEDs can accelerate the transition to LEDs in locations where aesthetic and environmental concerns have slowed adoption. This technology not only retains the nostalgic ambiance of traditional HPS lighting but also leverages the benefits of LEDs, such as higher energy efficiency, longer lifespan, and the elimination of mercury. This innovation paves the way for a more sustainable and visually harmonious lighting solution in urban and residential areas.

Features of Outdoor Lighting with Nichia HPS Color LEDs

1. Mercury-Free Lighting

Nichia HPS color LEDs eliminate the use of mercury, a significant environmental and health hazard associated with traditional HPS lamps. This aligns with global regulations and the movement towards a mercury-free society.

2. Instantaneous On/Off Cycling

Unlike HPS lamps, which take minutes to reach full brightness, Nichia's HPS color LEDs offer instantaneous on/off capabilities. This feature supports smart lighting solutions, enabling sensors to control lighting based on pedestrian or vehicular presence, thus saving energy.

3. High Efficacy and Longevity

HPS color LEDs surpass HPS lamps in luminous efficacy and offer a lifespan up to 2.5 times longer. This reduces the frequency of replacements and maintenance, particularly in hazardous or hard-to-reach areas.

4. High Color Rendering Index (CRI)

With a CRI of Ra≥70, these LEDs provide improved color visibility, making environments feel safer and more vibrant while maintaining the nostalgic atmosphere associated with HPS lighting.

4. Vivid Red Colors:

Nichia HPS LEDs have significantly higher red component in the emission compared to High-Pressure Sodium lamps, that enables vivid red colors, with high luminous efficiency and long service life.

5. Reduced Light Pollution

HPS color LEDs minimize light pollution compared to High-Pressure Sodium lamps, preserving the natural night sky, protecting ecosystems, and reducing glare that can affect human sleep patterns and overall well-being.
