T3-HID High Output

Product Overview and Benefits

This reflector was engineered for high optical efficiency and long pole spacing, making it ideal for energy-saving projects. The simple replacement of the reflector allows for the substitution of 150W luminaires with 100W luminaires (and 250W with 175W), resulting in a minimum energy savings of 50W. Additionally, this solution significantly enhances lighting levels, uniformity, and overall coverage.

The graph illustrates the results of field tests conducted on roadways, comparing a luminaire with the T3-High Output optic to a typical commercial HID optic. The T3-High Output optic effectively redistributes the excess light that typically accumulates directly beneath the luminaire to the sides. This design achieves enhanced lateral coverage with uniform lighting, eliminating shadows between luminaires, all while facilitating lower electricity consumption.

The Challenge of Conventional HID Optics

Why Was a New Design Necessary? Traditional HID optics in street lighting luminaires often struggle to manage the luminous flux reflecting from the upper portion of the reflector, which leads to substantial efficiency losses and light control. The interaction of light rays with the lamp and excessive internal reflections cause the optic to behave more like a Lambertian emission source. As a result, light intensity decays rapidly with distance.

This reduces the effective lighting range of most conventional luminaires. Even those rated for medium curves or high efficiencies often fail to produce sufficient candela intensities to provide acceptable illumination on the roadway. This inadequacy typically necessitates increasing the lamp’s power or the mounting height—a costly and common industry practice.

The Solution

The T3-High Output optic was engineered to optimize to collect and transfer the luminous flux and mitigate the inherent distance losses associated with point source radiation. The key to this approach lies in the use of concentrator reflectors that generate virtual images of the lamp’s arc.

In this way, additional to a single physical light source, the optic simulates the presence of two virtual light sources, enabling a much more precise beam control, a wider light distribution, and superior uniformity without sacrificing efficiency, reaching Distribution T3-Medium with an optical efficiency of 86%.
