How to evaluate the light decay speed of LED optoelectronic products?
Publish Time: 2024-09-19
During the use of LED optoelectronic products, the light decay speed is an important performance indicator. Too fast light decay will affect the lighting effect and service life, so evaluating the light decay speed is crucial for choosing high-quality LED optoelectronic products.
First, you can get a preliminary understanding of the light decay by looking at the product's specifications. Some regular LED optoelectronic products will mark the light decay curve or the percentage of light decay within a certain period of time. For example, some products may indicate that the light decay does not exceed 30% after 10,000 hours of use. These parameters can be used as a reference for evaluating the light decay speed.
Secondly, actual testing is an effective way to evaluate the light decay speed. Under the same environmental conditions, multiple LED optoelectronic products of the same model can be lit at the same time, and their luminous flux can be measured regularly using professional optical instruments. The speed of light decay is calculated by comparing the changes in luminous flux at different time points. Generally speaking, the faster the luminous flux decreases, the faster the light decay speed.
In addition, it is also important to consider the use environment of LED optoelectronic products. Harsh environments such as high temperature and high humidity will accelerate light decay. If the product is used in such an environment, the light decay speed may be faster than in a normal environment. Therefore, when evaluating the light decay speed, it is necessary to make a comprehensive consideration in combination with the actual use environment.
You can also refer to the use experience and evaluation of other users. Look for user feedback about the product on the Internet to understand the light decay they observed during actual use. If many users report that the light decay is too fast, then the light decay speed of this product may be relatively high.
In addition, brand and quality are also factors that affect the light decay speed. Well-known brands usually pay more attention to product quality and performance, and their LED optoelectronic products may use better chips, heat dissipation design and packaging technology to reduce the light decay speed.
In short, evaluating the light decay speed of LED optoelectronic products requires comprehensive consideration of product specifications, actual testing, use environment, user evaluation and brand quality. Through scientific evaluation methods, LED optoelectronic products with slower light decay speed and stable performance can be selected to meet different lighting needs.
