How to check the luminous flux of LED fluorescent tube
In the LED industry, one method of product quality and function test is to calculate the luminous flux. The so-called luminous flux is the energy generated by point light source or non-point light source in unit time, in which those who can produce vision become luminous flux. The unit of luminous flux is LM. Within the scope of conforming to international norms, 1 LM is defined as the luminous flux of a candlelight light source in the unit solid arc angle.
Therefore, from the definition of luminous flux, it is used to describe the size of the total luminous action of the light source. Therefore, the greater the intensity of the light source, the more luminous flux will occur, and the luminous flux is equivalent to the light power. The so-called equivalence is related to the size of the power, which is also proportional to the structure of the light source.
In terms of the use of LED tubes, the SMD lamp beads are selected as the light source to produce a certain degree of luminous flux. If the packaging is better, the role of luminous flux will be more obvious. Therefore, when selecting LED fluorescent tubes, you can refer to the function and brand of the encapsulated lamp beads. After the assessment at the light source unit is completed, The equipment can be used to test the luminous flux of an LED fluorescent tube.
According to the specification of high lumen, it is defined whether the luminous flux of the equipment conforms to the specification of the place where it is used. If it does not meet the standard, the lamp tube with high power can be selected. Therefore, it is proved that for the place where LED fluorescent lamp is selected, the lamp tube with appropriate power can be selected according to its luminous flux.

How to replace the LED fluorescent tube
1. To install a new fluorescent tube, insert the lamp pin into the lamp holder and roll the lamp tube to fix it. If the lamp turns dark, shining or flickering, please replace the lamp. After replaceme
