Nowadays, parents are more and more concerned about their children's eye problems. Usually, children are under a lot of pressure to study. They often stay up late at night to do homework, read and study, so they will inevitably have myopia. In the final analysis, it is caused by inappropriate light, so many parents have begun to buy table lamps for their children to protect their eyes.
What many people don't know is that the light source of the desk lamp is also very learned . According to the degree of popularity, the light sources of table lamps can be roughly divided into three types: LED lamps , fluorescent lamps and incandescent lamps . Among them, incandescent lamps are the traditional light source, fluorescent lamps are the light source in the middle of development, and LED is the current mainstream table light source.
Different lighting fixtures, there are many differences between them, the following are their differences and advantages and disadvantages:
1. Incandescent lamp
Light-emitting principle: Incandescent lamps use the principle of tungsten filaments to emit light. When energized, the tungsten filaments are heated to generate light.
Advantages: The price is lower, the color temperature is softer, the light emitted is similar to natural light, and there will be no flickering and glare during use.
Disadvantages: high energy consumption, relatively short service life, a large amount of heat energy will be generated when the tungsten filament emits light, and it is not suitable for long-term lighting. At the same time, it is not very environmentally friendly, because not only consumes a lot of energy, but also is difficult to recycle.
2. Fluorescent lamps
Luminescent principle: Fluorescent lamps place a certain amount of mercury vapor and some phosphor powder in the lamp tube, and the phosphor powder is excited to emit light when electrified.
Advantages: long service life, energy saving and environmental protection, no heat, less adverse effects such as glare and stroboscopic, suitable for places that require a lot of lighting.
Disadvantages: It is easy to flicker during cold start and cause damage to the eyes. Contains mercury inside which can have an environmental impact during disposal.
3. LED lights
Light-emitting principle: LED lights adopt light-emitting diode technology, and the efficiency of converting electrical energy into light energy is higher than that of fluorescent lamps and incandescent lamps. The luminous efficiency can reach 120lm/w, the color temperature is optional, the service life is long, and the luminous efficiency will not decline over time. .
Advantages: energy saving and environmental protection, low energy consumption, long service life, uniform light, stable light emission, strong shock and pressure resistance, no mercury, no ultraviolet radiation, no adverse effects such as glare and strobe.
Disadvantages: The price is relatively high, but it is only relative. Overall, it is still very affordable, and the high-quality LED lights have excellent eye protection effects.
Therefore, it is better to choose a high-quality LED table lamp brand for children's homework table lamps . Here are a few LED eye-protecting table lamps suitable for children:

Built-in 20 million nano light guide points, up to 1800 times of multi-level diffusion, so that the light comfort is increased by more than 48%, and the eye protection is further strengthened. It has passed the German TUV-SUD certification, Rg0 no blue light certification, IEEE no frequency Flash certification, myopia prevention and control certification, etc., is the best desk lamp for eye protection and anti-myopia, which can reduce the risk of myopia by more than 80%.
Top2: Hasvision VL225B-1 table lamp
Recommended Strength: 4⭐
Hassight VL225B-1 table lamp has good dimming, with intelligent photosensitive automatic adjustment function, which is convenient for children to use in different lighting environments. The diameter of the light-emitting surface is 205mm, and the light is relatively wide. It also adopts the surface + ring light design, and the illuminance meets the AA standard , bright and uniform. There is a small light source on the back of the table lamp, which can be used as a night light at night without dazzling. Ra95 color rendering index, the color is true and does not have color difference, but occasionally there will be reflections and glare.
Top3: NVC Galaxy Table Lamp
Recommended Strength: 4⭐
The NVC Galaxy table light has good light safety, Rg0 anti-blue light, anti-strobe, and reduces eye fatigue. The light is relatively uniform. The light-emitting surface designed with a diffuse reflection structure meets the AA-level standard for illuminance and uniformity. The light can be turned off to remember the brightness, and there is no need to adjust the light next time. The lamp holder is made of T2.5 tempered glass, which has a good texture. You can set a 45-minute timer reminder, a 60-second delay to turn off the light, and slide dimming, which are more convenient, but sometimes the intelligent sensor automatic dimming is not very effective.
Top4: Panasonic Zhihao table lamp
Recommended Strength: 4⭐
The Panasonic Zhihao table light has sufficient light, using 91 Panasonic custom-made LED lamp beads, the illuminance meets the AA standard, and the brightness can be automatically adjusted by intelligent sensing, which is convenient for eye protection. The light source is side-illuminated, diffuse and uniform, which can reduce direct glare. The color rendering index meets Ra97, and the color reproduction is good. There is a visual touch panel on the base, and you can set a 30-second delay to turn off the lights and a 45-minute timed break. The overall material is ABS, but the light body is heavy, and it is difficult for children to use.
