LED lamps have successfully replaced traditional high-pressure sodium lamps and metal halide lamps with their excellent high efficiency and long service life, becoming the mainstream choice in the field of road and tunnel lighting. In the current road and tunnel lighting market, the commonly used LED lamps mainly rely on the technology of blue light LED excitation phosphor to generate light sources. However, the phosphor-free LED lamps involved in the T/CSA 085-2023 standard use a technical solution of mixing light with LED chips containing at least two main wavelengths. Compared with traditional phosphor LED light sources, this phosphor-free LED light source shows higher light efficiency and lower light decay in the low color temperature area, while effectively saving precious rare earth resources. The standard provides detailed specifications for the technical indicators of phosphor-free low color temperature LED lamps for road and tunnel lighting, providing clear product guidance and standards for the application of such LED lamps.
In addition, phosphor-free LED lamps also have better color reproduction performance, which can more realistically display the original color of objects, thereby improving the visual comfort and experience in road and tunnel lighting environments. Due to the relatively simplified structure of the light source, the light decay and color temperature drift problems that may be caused by the phosphor layer are reduced, making the maintenance cost of the lamp lower and the service life longer. With the continuous advancement of technology and the further reduction of costs, phosphor-free LED lamps are expected to be more widely used and promoted in the field of road and tunnel lighting, becoming an important trend in the development of lighting technology in the future.
In addition, phosphor-free LED lamps also have significant advantages in environmental protection and energy saving. During the production and use of traditional phosphor LED lamps, phosphors may have a certain impact on the environment, while phosphor-free LED lamps avoid this problem and are more in line with the current green and low-carbon environmental protection concept. At the same time, due to its high-efficiency light source conversion capability, phosphor-free LED lamps can significantly reduce energy consumption and carbon emissions at the same brightness, making a positive contribution to energy conservation and emission reduction.
