What is the general appearance of eye protection lamps
Many people buy eye protection lamps and ask what the eye protection lamps look like and whether the lamps are good or not. What? In fact, since it is an eye protection lamp, it means that it is not an LED eye protection lamp, because the LED eye protection lamp is composed of countless diodes. Most of the energy-saving lamps are U-shaped lamps, and the eye protection lamp is relative to the energy-saving lamp and the incandescent lamp. Of course, there are also incandescent lamps used in the eye protection lamp, but the design is optimized. For the knowledge of eye protection lamps, I hope everyone can understand the following knowledge.
1, as long as it is a gas discharge (ie, fluorescent lamp, etc.) lamp, it will not work properly without a ballast, but the energy-saving lamp (that is, between the screw of the lamp and the lamp tube) There is a plastic-wrapped part), the ballast and the lamp are a whole and cannot be “divided” by themselves (if someone who knows electronics can disassemble and repair);
2. If the placement distance of the lamp remains the same (referring to the distance from the human eye to the lamp), it is best not to change the power originally used for the eye protection lamp, that is, the original given power should be used when replacing the lamp, but if After a proper distance, it is also possible to replace the new lamp with a slightly higher power, as long as it is not too large, for example, if you replace the energy-saving lamp with more than 32W, it is too bright;
3, generally It is best not to easily replace the lamp tube. There are many eye protection lamps and the ballast they use as a whole, so you generally can’t replace them yourself.
4, “Double U” or “Triple U”, the lamp with screw socket and the pin-type “H-type” or “Dish-type” also There are “circumferential” type lamps, although they are energy-saving compared to incandescent lamps, but they are not special eye-protection lamps or energy-saving lamps. A very small “pin”, that is, like an ordinary fluorescent lamp), the ballast and the lamp are separate, and new lamps with the original power must be used, and there are two new lamps (with Starter, used for inductive ballasts) pins, or four pins (there is no starter in the lamp, generally used for electronic ballasts) can not be mistaken, must be the same as the original; In addition, the brightness of the lamp tube of the eye protection lamp is basically the same as that of the energy-saving lamp, which is generally equivalent to about 5 times the brightness of the incandescent bulb of the same power.
I hope everyone can view the eye protection lamp more reasonably after understanding the above facts.
