"Six-step method" to judge whether the LED light source is good or bad

For all lighting fixtures, whether it is general or the most popular LED fixtures, it is composed of three parts: housing, light source and electrical lamp. Among the three components, the light source and the electrical appliance are the most important. A good electrical appliance must be matched with a high-quality light source to achieve the best lighting effect.

So if you want to have a good luminaire, you must have a good light source. Below, I will introduce you to several criteria for choosing a good quality light source:

1. Check the luminous flux, which is how much light the light source can emit;

2. The color temperature of the measuring device, that is, the color temperature emitted by the light source, the light emitted by the general lamp has the distinction of "yellow" and "white". In the professional field, Huang Guang is "below 3000k", white light is "5000k or more", and between "3000k-5000k" is the intermediate color;

3. Observe the color rendering of the luminaire, that is, whether the luminaire source can completely illuminate the color of the object. The industry generally believes that sunlight can best reflect the true color of an object;

4. Determine the average life of the luminaire. For example, there are a number of light sources. The average life of the general number of light sources is the average life of the products. Note that the average life expectancy is at least one and a half years.

5. Test the light effect of the light source of the lamp, and the lamp with high light efficiency will consume less electricity for the same long time, so the lamp with high light efficiency is more energy-saving;

6. Observe the stroboscopic rate of the luminaire. The strobe is the number of flashes of the luminaire within one second. If the strobe is too large, it will cause huge damage to the human eye.

When you purchase the lamps, you can select the best quality lamps according to the above criteria.
