What's the luminous flux?
The luminous flux of an LED lens is usually the total brightness of the light beam produced by the lens after it has been passed through and focused, usually measured in lumens (lm). This value can be used to measure the brightness and efficiency of an LED lamp. The luminous flux of an LED lens depends on a number of factors.
What are the factors affecting luminous flux？?
1. The luminous efficiency of the LEDs.
Firstly, the luminous efficiency of the LED chip has a great influence on the luminous flux of the lens. The higher the luminous efficiency, the brighter the lamp will be and the more luminous flux it will produce.
2. The shape and size of the lens.
The shape and size of the lens has an effect on the luminous flux. Typically, the larger the lens size, the greater the luminous flux will be. However, if not designed correctly, the lens may also cause light to be scattered or reflected, thus reducing the efficiency of the luminous flux.
3. The material of lens.
The material of the lens also has an effect on the luminous flux. Differences in lens material can cause light to be scattered or reflected in different ways, thus affecting the production and efficiency of luminous flux.
Conclusion:
Luminous flux has an important place in optical design. For LED lamp manufacturers, optical design is an important part of developing lamps and related products. The optical design ensures that the lamp works best and increases the efficiency of luminous flux production and use. Optical design not only improves the performance of LED lamp products, it also improves the marketability of LED lamp products.
In LED lens design, optical tools such as various types of software are used to analyse and adjust different factors in order to get the most suitable lens design and ensure that the performance of the lamp is maximized and the engineer's objectives are met. Factors such as luminous efficiency, lens shape and size, and lens material should be considered in the design to obtain the best luminous flux.
