Eye protection blackboard lamp manufacturer: why the teacher's eye protection lamp is not bright enough
Classroom eye protection lamp is literally a lamp used in the classroom, so the main collective using it is the students, and the students' body and mind are in a dry growth state, and the demand for eye use is high. Therefore, the use of lamps should be good, otherwise the too dark environment will form a bad shadow on the students' eyes, so when the lamp is not on, it must be handled in time. Then again, what is the reason why the lights don't work?
1. Classroom lights will darken if they are used for a long time
No matter how long a good quality lighting lamp is used in a day, the loss of many parts will be greater and greater, and then the lighting function provided will decline.
2. Insufficient current will also reduce the lighting effect of classroom lamps
One day's unstable power supply voltage will also cause the lamp to dim. In addition, the voltage change of the power grid will also affect the brightness of the lighting lamp. For example, in the evening, there is a peak of power consumption, and the load of the power grid is relatively high. At this time, the current passing through the wire is relatively large. Then, according to Ohm's law, u = R, the voltage consumed by this wire is relatively large, so the voltage of these electrical equipment assigned to the lighting lamp will also drop, resulting in dimming.
3. Excessive dust accumulation affects the lighting function of classroom lighting
When the lighting lamp is used for a long time, the dust will accumulate more and more through the two accumulation eyes, and then hide and affect the lighting effect of the lighting lamp, resulting in the weakening of the diffusion of light after passing through the dust, and then the phenomenon of poor height.
Therefore, when you find that the height of the classroom lamp is not good, see if it is caused by too thick dust. If the height of the dust is not good, you can clean it, and then restore the lighting brightness of the lamp. However, if it is caused by the aging of internal parts, Xiaobian advocates timely replacement to avoid excessive loss and damage to the lighting.
