Room lamp is a kind of lamp specially used for student lighting, and is also mostly used for writing and reading occasions. The lamp usually uses high-frequency fluorescent lamp, LED lamp, DC eye guard table lamp, etc. as the light source. The lamps with high price have certain eye protection effect. Its lighting mode has the characteristics of no stroboscopic, high luminous efficiency and no mercury and other harmful heavy metals. In theory, the use of LED light source can protect users' eyes to a great extent.
The choice of classroom lighting does not depend on the price and the price. The important thing is to see its eye protection function. Of course, if it is too cheap, don't consider it. After all, you get what you pay for. We should still choose lamps with reasonable price and good quality according to the service conditions.
Classroom lights will darken if they are used for a long time
Once the lighting lamp with good quality is used for a long time, the loss of many parts will be greater and greater, and the lighting effect provided will be reduced.
Insufficient current will also reduce the lighting effect of classroom lamps
Once the power supply voltage is unstable, it 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, there is a peak power consumption at night, 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 = IR, the voltage consumed by this wire is relatively large, so the voltage of these electrical equipment assigned to the lighting lamp will also be reduced, resulting in dimming.
Excessive dust accumulation affects the lighting effect of classroom lamps
With the use of the lighting lamp for a long time, more and more dust will accumulate over time, which will cover and affect the lighting effect of the lighting lamp, resulting in the weakening of the dissemination of light after passing through the dust, resulting in the phenomenon of insufficient brightness.
Therefore, when you find that the brightness of the classroom lighting is not enough, see if it is caused by too thick dust. If the brightness is not enough caused by dust, you can clean it to restore the lighting brightness of the lighting. However, if it is caused by the aging of internal parts, Xiaobian recommends replacing it in time to avoid damage to the lighting lamp due to excessive loss.
