What should a good LED downlight be?
First, it should be bright enough.
No matter what kind of lamp, lighting is the most fundamental attribute.
There is a very important reason that why LED lamps have become the mainstream of the lighting industry, that is brightness.
People may say that it is easy, just increase the power.
But the "brightness" we are talking about here is not simply bright, but high luminous efficiency. That is, under the same wattage, more light is obtained.
The light efficiency of downlight can be over 100lm/w, under the same wattage, it can bring more light to people.
Second, light of the LED downlight should not offending to the eye.
Since the high brightness, if not handled properly, it will be very dazzling. How can the light of LED downlight not be dazzling?
There are two channels: one is the layout of the LED lamp beads, and the other is to choose a suitable lampshade.
The light beads of LIGHT VICTOR LED downlight are evenly distributed, thus, the light emitted is uniform, which of course will not dazzling.
In addition, downlight are generally with high quality optical lens mask. The light emit out through the lampshade is more soft like moonlight.
Third, it should with no flicker
In order to protect eyesight and reduce the impact on human physiology and psychology, no matter when choosing or designing LED lights, special consideration must be given to the problem of light flickering.
The LED downlight is equipped with driver device with flicker suppression function, so that the light emitted will not flicker due to alternating current.
Fourth, its light color rendering index should be high enough
Color rendering is the character of light to restore the color of the object itself. The higher the color rendering index, the more realistic the color people see; on the contrary, the more unrealistic the color is, and the long-term use of the eyes under the low color rendering light will also cause harm to the eyes.
In the early years, there were almost no requirements for color rendering. It's not because people's eyes were more powerful at that time, but because the color rendering of the incandescent lamps used at that time was very high, which was infinitely close to natural light.
However, after entering the LED era, color rendering has become a necessary parameter when choosing lamps.
LED downlight CRI is generally >80, which can effectively restore the color of things and protect the eyes.
