As far as LED profession is concerned, one way to test the quality and performance of products is to calculate the luminous flux. The so-called luminous flux is the energy that occurs in a unit time through a point source or a non-point source, in which the visor becomes the luminous flux. The unit of light flux is lm. Within the scope of conformity with international norms, 1 LM is defined as the flux of the candle light source passing through the unit solid arc angle in an international norm.

Therefore, in terms of the definition of luminous flux, it is used to describe the magnitude of the total amount of luminous action of the light source, so the greater the intensity of the light source, the more the corresponding luminous flux will occur, and the luminous flux is equivalent to the light power. The so-called equivalence is the relationship between the magnitude of the power and the structure of the light source. Form a direct proportion.

In terms of the use of LED lamp, patch lamp beads are used as light source to produce certain degree of luminous flux. If the package is better, the effect of luminous flux will be more obvious. Therefore, when choosing LED fluorescent lamp tubes, we can refer to the performance of the packaged lamp beads, as well as the brand, and check at the light source element. After that, the device can be used to test the fluorescence of an LED fluorescent lamp.

According to the specifications of high lumen, it is defined whether the luminous flux of this equipment is in accordance with the specifications of the place where it is used. If it is not qualified, it can select the lamp tube with the corresponding high power. Therefore, it is confirmed from this aspect that the suitable power can be selected according to the luminous flux when selecting the place where the LED fluorescent lamp is used. The lamp tube.
