Mijia Mi LED Smart desk lamps have been released for a long time. That year, it won the 2017 iF Design Gold Award. From an industrial design perspective, Mijia LED Smart desk lamps have reached a very high standard.
I still like the red line at the end of the light arm. Without this red line, the overall feeling is too rigid.
There is only one physical button on the entire desk lamp for interaction:
- Click to switch on / off.
- Double-click to enter the preset mode.
- Rotate to adjust brightness.
- Press and hold to adjust the color temperature.
All four functions are realized through this one button. Very simple and easy to understand.
Of course, since it is called a smart table lamp. So it can also be controlled remotely via Mijia App. It also supports Apple Watch controls.
You can also set timing switches in the App. Or turn on small features like 45-minute automatic reminders.
Light source for Mijia LED Smart desk lamps. From 42 LED lamp beads. 21 of them are 2700K warm white light, and the other 21 are 6500K cold white light. It’s a bit bluer than the 5700K color temperature lamp beads used by the WiT Genie I tested before.
Therefore, the color temperature change of Mijia LED Smart desk lamps is the same as other LED desk lamps. It is also achieved by switching the brightness ratio of the two color temperature lamp beads.
On the glare control. Although Mijia LED Smart desk lamps are not as good as WiT’s arc-shaped products that support partitioned lighting. But compared to the traditional round lampshade table lamp will still be much better. The human eye looks directly at the light emitting area from the side, and it is not too glare. When the light tube is placed close to the screen, the screen glare caused is also less.
The principle is also due to the lens design inside Mijia LED Smart desk lamps. Keep the light path down as far as possible, not to the sides.
At the same time, the outer lampshade of the light emitting module is also frosted. This makes the light source look softer. Strobe aspect. From the perspective of stroboscopic fluctuations, it really exceeds 1000hz. So for the human eye, the impact is really small.
But we also know. If you want to reduce the brightness of the LED to a very low level, then PWM is still the easiest way to achieve it. So when the brightness modulation of Mijia LED Smart desk lamps is the lowest. Through high-speed photography of more than 1000 frames per second. We will also find that there is a flicker on the Mijia LED Smart desk lamps on the right side of the picture below, but the WiT Genie on the left has not appeared.
Brightness and color temperature test
First I tested the brightness range of Mijia LED Smart desk lamps. The test point is 37 cm directly below the geometric center point of the lamp group. Because Mijia LED Smart desk lamps use stepless adjustment, the six gears below are tested with rotary buttons.
we can find out. The knob of Mijia LED Smart desk lamps has a large brightness change in the lowest and highest two steps. The other gears change evenly. The maximum brightness can reach a level of about 960lx.
In terms of color temperature. The measured Mijia LED Smart desk lamps can cover the range of 2700k ~ 6600K. However, when adjusting the color temperature through the knob, the color temperature displayed by the App will be slightly different from the actual measurement. There are 6 positions for adjusting the color temperature with the buttons. The six gears in the App show: 2700K, 3200K, 4000K, 5000K, 6000K, 6500K.
But after the actual measurement. The color temperatures of these 6 gears are 2703K, 3086K, 3887K, 4944K, 6182K 6602K. In some gears, there is a gap of about 100K ~ 150K from the theoretical value. But the human eye can hardly see it.
One thing I don’t quite understand. For indoor light sources, more than 5500K can be said to be very blue. I don’t know why Xiaomi put the cool color temperature to 6500K level. I hope that when you use it, try to keep the color temperature within 5000K.
Light distribution uniformity
Under daily ambient light. The desktop can be divided into a main work area and a secondary work area. Corresponds to the needs of long-term reading and writing and short-term reading and writing respectively. The main work area needs more than 500lx illumination, while the secondary work area needs more than 300lx illumination.
The performance of Mijia LED Smart desk lamps is also conceivable. Because its light-emitting area is long. So when facing a square table, the effective lighting area will also be larger than the round lampshade.
The illuminance directly below the geometric center of the desk lamp is 970 lx, which meets the illuminance requirements of the main operating area. The illuminated area is almost the size of a 15-inch laptop.
Conclusion
Mijia LED Smart desk lamps. As a $ 40 product, it can be said that it has reached the best performance at this price. Its biggest advantage is that it solves many consumers’ demand for desk lamps.
Advantage:
- Long LED light source. It is brighter than traditional incandescent lamps and effectively illuminates a larger area.
- The lamp housing and lampshade has a light path design. There is less glare on the side and the light is uniform.
- Adjustable color temperature from 2700K to 6600K. Meet the needs of day to night.
- Can be controlled remotely with App.
- No flicker was visible to the naked eye.
Cons:
- The height of the table lamp is immutable. Overall a bit short.
- The lamp arm can only tilt up and down. Can’t rotate left or right.
- At the lowest brightness, the strobe frequency will decrease.
- Less precise when adjusting with buttons.
