Understanding and Learning about LEDs: 4. What is a High Color Rendering White LED?

Understanding and Learning about LEDs: 4. What is a High Color Rendering White LED?

Developing light that is closer to natural light.

White LEDs are used as the lighting source, but there are several methods to create that white light. One method is to combine red, green, and blue LEDs. This method has good color rendering properties but faces challenges in terms of cost and luminous efficiency. Therefore, a method that combines blue LEDs with yellow phosphors has been used so far, as it allows for relatively easy attainment of high luminous efficiency. However, this method has the drawback that the emitted color is a pseudo-white, making it unsuitable for applications that require high color rendering properties. Additionally, there is a method that creates white light by combining near-ultraviolet LEDs with blue, red, and green phosphors, but this is said to have issues with brightness. In response, Citizen Electronics has adopted a method that uses blue LEDs to excite red and green phosphors. This method serves as a light source for LEDs with high color rendering properties while overcoming challenges related to cost and efficiency.

Industry's smallest class LED for spotlight lighting.

Industry's smallest class LED for spotlight lighting.

LED lighting that contributes to the miniaturization of equipment and the improvement of equipment design! Ideal for commercial facility lighting, facilities, stores, hotels, restaurants, and more!

We have consolidated our core technology to achieve a maximum luminous efficiency of 115lm/W (3000K/Ra90, Tj85, under rated drive conditions). This allows for brighter illumination with less power, contributing to energy savings in lighting fixtures. Additionally, we have improved long-term reliability and gas resistance characteristics, which not only enhances energy-saving effects due to increased luminous efficiency but also extends the intervals for replacing or repairing LED light sources and fixtures, thereby reducing environmental impact. By improving the amount of light obtained per package, we also contribute to the miniaturization of lighting fixtures and cost reduction. <Applications> For spot lighting in facilities, stores, hotels, restaurants, etc. For applications requiring narrow angles 【Features】 - Easy optical design with lenses and other components - Contributes to miniaturization and design aesthetics of fixtures - Offers one of the smallest sizes in the industry (LES size φ2.4mm) For product details, please visit our website.

LED lighting that improves luminous efficiency and contributes to energy saving in lighting fixtures.

LED lighting that improves luminous efficiency and contributes to energy saving in lighting fixtures.

LED lighting with an improved luminous efficiency of up to 7-8%! It contributes to energy savings in lighting fixtures and offers a comprehensive lineup that makes it easy to replace conventional products!

We have consolidated our core technology to achieve a maximum luminous efficiency of 142 lm/W (3000K/Ra90, Tj85, under rated drive conditions). This allows for brighter illumination with less power, contributing to energy savings in lighting fixtures. Additionally, we have improved long-term reliability and gas resistance characteristics. The energy-saving effects from enhanced luminous efficiency, along with longer intervals between replacements and repairs of LED light sources and lighting fixtures, also contribute to reducing environmental impact. By improving the amount of light obtained per package, we also contribute to the miniaturization of lighting fixtures and cost reduction. <Applications> Street lights, tunnel lights, floodlights, downlights, stadium lighting, etc. 【Features】 - Luminous efficiency: up to 142 lm/W (3000K/Ra90, Tj85, under rated drive conditions) - Supports a lineup of color temperatures and color rendering - Easy replacement from conventional products, covering 3W to 480W with 14 varieties across 4 packages (at Tj85°C) and reducing color variation - Improvement in maximum rated drive current For product details, please check our website.
