HercuLux Optics outdoor standard model product Turbuine series of glue lenses, the first application of Self-adaptive glue technology in the outdoor lenses, breaking the efficiency limit of the original lens, achieving efficiency of more than 100%. Partners in the same industry question this: can Turbine series lenses really achieve efficiency ≥ 100%? Next, we will proof it through several practical application cases.

Technical solutions

When light passes through the interface with different refractive index, it will reflect at the interface. Interface reflection will produce light loss, calculated by the formula of light loss, each passing through a surface; there will be about 4% of the optical loss. As can be seen from the following picture, the light loss is about 8% when it passes through the lens.

By comparing the ordinary lens and the Turbine series of glue lens in the figure below, the self-adaptive glue technology  avoid two interface reflections and achieve an efficiency of more than 100%.

Summary of test data

From the data, we can find that when the color temperature is below 4000k, the efficiency of the lens is very high, even more than 100%. Raise the color temperature, the efficiency is slightly improved. But it can also maintain a higher efficiency.

As the color temperature of the light source increases, the drift value increases correspondingly.

Lepower Optoelectronics, special custom 5050 light source for glue dispensing technology, can float within the black body line after adding a glue lens.

PS: Founded in 2008, Lepower Optoelectronics is a leading domestic listed company in the research, production and marketing of LED packaging products. The group's business mainly focuses on the LED packaging industry. Based on the technology, quality and scale advantages of the enterprise itself in the field of LED packaging, it actively extends to the field of LED application lighting, and creates a professional brand of LED lighting - Brightening lighting.

For each color temperature range, the color rendering index has a certain increase.

The measured data show that the efficiency of Turbine lenses can reach 100% or even over 100% by using self-adaptive glue technology.
