校园护眼灯价格越高越好吗?

来源:http://www.wfjszmd.com/ 日期:2021-10-06 发布人:wanfeng 浏览次数:

室照明灯是专门用于学生照明的一种灯具,也多用于书写、阅读场合的照明,该灯具通常使用高频荧光灯、LED灯、直流护眼台灯等作为光源。价格比较高的灯具,具有一定的护眼效果。它的照明方式具有无频闪,发光效率高,不含汞等对人体有害的重金属等特点,采用LED光源理论上可以在很大程度上保护使用者眼睛。
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.
选择教室照明灯,不在于价格的高低以及贵贱,重要的还是要看它的护眼功能,当然太便宜的还是不要考虑了,毕竟一分钱一分货。我们还是应该根据使用状况选择价格合理、质量良好的灯具。
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.
教室照明灯用久了会导致变暗
Classroom lights will darken if they are used for a long time
质量再好的照明灯一旦使用时间过长,很多零部件的损耗程度就会越来越大,从而所提供的照明效果会降低。
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.

电流不足也会导致教室照明灯的照明效果降低
Insufficient current will also reduce the lighting effect of classroom lamps
一旦供电电压不稳也会导致照明灯变暗。除此之外,电网的电压变化也会影响照明灯的亮度的。比如晚上是用电高峰,电网的负荷比较高,这个时候,穿过电线的电流也就比较大。那么,根据欧姆定律,U=IR, 这电线消耗的电压比较大,所以分到照明灯的这些用电设备的电压也会降低,导致变暗。
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.
灰尘堆积过多而影响教室照明灯的照明效果
Excessive dust accumulation affects the lighting effect of classroom lamps
照明灯的使用时间一长,灰尘经过日积月累会越来越多,从而遮盖、影响照明灯的照明效果,致使光透过灰尘后的散播变弱,从而导致亮度不够的现象发生。
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.
所以当发现教室照明灯的亮度不够时,看看是不是过厚的灰尘导致的,如果是灰尘造成的亮度不够可以进行一下清扫,从而恢复照明灯的照明亮度。但如果是因为内部零部件的老化造成的,小编建议及时进行更换,避免损耗过重而导致照明灯损坏。
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.
