Is the LED desk lamp good for the eyes?

1. From the perspective of electronic appliances

LED desk lamp, because the light source uses LED, LED is DC In theory, the light emitted by light-emitting devices is different from the light emitted by our previous generations of light sources. Traditional light sources including energy-saving lamps, metal halide lamps, incandescent lamps, etc. are all AC and will follow the input current of the civil power grid. The frequency changes (my country's power grid is 220V, 50HZ), so the frequency fluctuation of AC causes the traditional light source to flicker. Working and studying under this light source for a long time will cause damage to the eyes. If you use an LED desk lamp, it depends on whether you know how to choose it. Not all LED desk lamps are flicker-free. If it is a desk lamp using rechargeable batteries, the LED lamp beads will not be directly visible on the light-emitting panel, and there will be no glare. It can protect your eyes. Please note that you must choose one that is surface-luminous. The other is an LED desk lamp driven by a constant current power supply. If you don’t understand this product yourself, you still need to buy it from a reputable manufacturer.

2. From an optical point of view:

When traditional light sources emit light, they will also emit red wavelength light waves, which you can understand as invisible infrared rays. This wavelength is above 780nm. Radiation can cause damage to the eyes. Most myopia is caused by working and studying indoors for a long time and relying too much on traditional lighting. The LED light source is mainly blue light core excitation phosphor. The wavelength of the light is between 380-780nm. There is no ultraviolet and infrared rays. A good LED light source (note that it is good, you usually see most of them in stores outside) No, all the good ones in China are exported.) Those with a color rendering index greater than 85 (the higher the color rendering index, the closer to natural light), have a relatively full spectrum, that is, they have green light waves at the same time, which is close to natural light. You can also I know that many times the treatment of myopia requires looking at green things, because it relies on green light waves to repair eye damage, at least it will not aggravate myopia.

How many watts is suitable for an LED desk lamp?

A 25-watt LED desk lamp is suitable. For students, 25 watts is enough. A 25-watt LED desk lamp is suitable. It is very useful and can be considered by students. The LED desk lamp I use is 25 watts, which I think is very bright and suitable. 40 watts is too bright and inappropriate, but 25 watts is just right.

What to do if the LED desk lamp is broken

First of all, we need to see how bad it is. If only the lamp bead of the desk lamp is broken and does not light up, it means that the resistor has appeared. Problem, this requires replacing the lamp beads and resistors. As for how to replace it? It's better to take it to a specialized repair shop for repair. If you are replacing lamp beads, you must follow the instruction manual of the desk lamp you purchased at the time. The size and style of the lamp beads must match to avoid safety accidents. There are thousands of unexpected situations in which LED desk lamps break down. We cannot rule them out one by one, but we can solve them one by one with clever tricks.

The second situation is that all the lamp beads are not as bright as before, which means that the battery inside the desk lamp may be broken and needs to be replaced. At the same time, check the one connecting the battery and power supply. Is the line broken? If the connecting line is broken, just replace it. We can't repair this. We don't have the equipment and facilities, and we can't find a way to repair it. The only solution is to replace it. In fact, what to do if the LED desk lamp is broken, it is just a small problem.

The third situation is that the light strip cannot switch normally. Generally, desk lamps can switch between dark light and bright light. If this is the case, there may be a problem with the regulator. Check it carefully first. Check the interface to see if it is loose or unreliable, and whether the regulator is broken. If the regulator is broken, it needs to be replaced. If the interface is tight, just tighten it firmly.

The fourth most common situation is that the light strip does not light up. This non-lighting can be divided into part not lighting up, or all not lighting up. If it is partially not lighting up, it will lead to such a situation. In many cases, either the circuit is short-circuited during transportation, or the lamp beads are broken due to voltage; or the welding is not connected properly during transmission. If this is the case, remove the lamp beads without cutting off the power supply. Cut off the bright part and prepare two-way plugs to insert into both ends.
