How to choose an LED smart eye-protecting desk lamp?

Compared with fluorescent lamps, LED lamps are currently popular on the market. Therefore, even if the residents of newly renovated houses are not unfamiliar with LED lights, then how to purchase an LED smart eye-protecting desk lamp?

1. Check the packaging and trademark logo: In China, mandatory LED light manufacturers are required to indicate the following points on the product packaging: rated current. Operating voltage range. High power. Rated frequency. Generally speaking, the trademark logo packaging printing of goods has a high cost performance, with clear font styles and is not easy to fall off. Wipe it with a soft dry cloth. The mark is clear and not easy to be wiped off. It has the manufacturer's trademark logo and relevant certification certificates. Counterfeit and shoddy products have poor packaging and printing quality, unclear font styles that are easy to erase, and lack the manufacturer's trademark logo and relevant certification certificates.

2. Observe the shape of the led tubes: LED table lamps are made of tricolor tubes and are grayish-white. When you cover them with your hand, they appear even whiter. Furthermore, from the perspective of led tubes, many lamps can be placed together for comparison. Most lighting fixtures with consistent appearance and specifications are made by bending equipment sheet metal, and the vast majority are mass-produced goods. The product consistency is good, the quality is easy to ensure, and the tolerance fit is good during maintenance. Of course, there should be no cracks in the middle of the socket in terms of appearance. Loose or prying marks. During the entire process of assembly and disassembly, the lamp base must not be loosened or bent. The plastic casing of the lamp is a flame-retardant rubber product. Generally, plastics are prone to deformation and flammable. They are strictly prohibited from being used in the production of LED lamps. From the outside, we can simply distinguish the two. The latter is smooth and lustrous, while the former has a similar layering effect to frosted glass.

3. Check the driving force: The lifespan of an LED desk lamp is not as long as the manufacturer claims, which is 50,000 hours. However, the diffused driving force certified by the EU on the market can basically exceed 20,000 hours. Since led lighting products have only been on the market for 2 to 3 years, it is unlikely that they can last for 5 to 10 years. Safe driving is not that bad. Therefore, most manufacturers will guarantee a 2-year service life.

4. Observe the operational characteristics: LED table lamps have two advantages: First, the higher the temperature, the easier it is to operate; Second, when the light is turned off, it is less likely to flicker. It is also worth noting that many LEDled energy-saving lamps are dim when turned on, which is not good for the lifespan of the bulbs. Youdaoplaceholder0 energy-saving lamps should have circuits and PCB boards inside.

When purchasing an LED desk lamp, it is necessary to first check the flicker frequency of the LED. If the stroboscopic height is also very harmful to the eyes, how can it be tested? Everyone should turn on the surveillance camera on their mobile phones, turn on the LED light, and then point the surveillance camera on the phone at the light source to see if there is any flickering. If the light source is relatively stable, it indicates that the quality of the lamp is very good. If the flicker is severe, it belongs to a inferior light source.
