Known as the thinnest full spectrum ceiling lamp — Meizu Lipro ceiling lamp evaluation

Yes, I am the one who sprayed Lipro wildly at meizu’s press conference. After thinking, I should not look at things with emotion, but with objectivity and rationality.

So, lui a lot of meizu lights, this time more samples, so ready to be divided into 3 articles to write, suction ceiling lights, down lights each one, cabinet lights + foot lights one.

See “zhuhai small factory” small? Is the light of ruran, which is the milk of god from all sides, “Ruran” or “ruhua”?

Give absorbing dome light is a name first, absorbing dome light does not have everybody to think of so LOW, absorbing dome light light is even and downy, use is extensive, lamplight is easy and practical completely no less than blind pour without advocate lamp, especially the dimensional illumination of room of old person room, child or study, absorbing dome light is very good choice.

First, appearance/structure/material

Model of absorbing dome light is sameness, and ply is in 10cm fluctuation normally, after installation, the likelihood can show overcrowding slightly drab, so, the design of super thin lipro also is one of the reasons that I evaluate it, the ply of whole lamp is less than 2cm.

After installation, the total height of the lamp body is about 2.6cm, and the lamps and lanterns are integrated into the decoration as far as possible to make the space more concise and clean.

Conventional ceiling lights are used positive luminous module light source, to achieve ultra-thin is relatively difficult, if too thin can only sacrifice light experience.

Lipro ceiling lamp can do the thickness of 2cm, is obviously a new way, with the side luminous + light guide plate out of the light.

In terms of the structure of the arrangement of light source, the combination of W + Y, obviously is to support the color temperature adjusting, light source base plate and shell together, and have been fixed, the shell is very large radiator, ensures that the heat dissipation, good heat dissipation can effectively slow down the speed droop, it is very important, whole lamp with two light source also makes the stability of the whole higher.

No problem isolated power supply, all welding, so the internal cables are not very orderly, if changed to plug and unplug interface, you can arrange the cables in good order, the manufacturer still chose to sacrifice assembly efficiency for stability.

The head that absorbs dome light is larger, the diameter that tests absorbs dome light is 50cm, to assure luminescence is uniform, the requirement to guide light plate is met very tall, can appear on the edge otherwise bright, middle dark circumstance.

Lipro ceiling lamp with two layers of light guide plate + a layer of resistance plate + a layer of protection plate design.

1 Separate the backplane circuit to protect the optical suite from damage.

2 Light blocking plate is non-transparent material, to ensure that the light source is only directed to the light plate diffusion, reduce light loss, avoid light leakage and other problems.

3 to the light source for the first time diffusion, so that the light can evenly fall on the sand acrylic, to avoid the problem of dark side light.

Sand acrylic light guide plate, secondary diffusion treatment of light source, make light uniform and soft, avoid staring at dazzling.

The difficulty is that the light guide plate 3 should fit perfectly with the light source. It can be seen that lipro ceiling lamp has made a lot of effort in the design and materials, and it is not so simple to take a few accessories and assemble them.

In turn, this structure can prevent mosquito invasion.

All this is to be able to evenly light and light leakage, we can see the effect, as shown in the figure:

Ps: Readers who are familiar with me know that I take pictures with an old phone, so that you get better than you see, to avoid confusion.

Focus on the luminous surface

Speaking from the light

The uniformity and softness are very good. Under the highest brightness, there will be no obvious dazzling when looking directly at the light source. The design of slowly turning on the light and slowly turning off the light is very careful, and the brightness is 0-100% in about 2 seconds (it can be set in the APP).

Figure control is above medium level, directly below the light, the hand is about 50cm away from the working face, there will be no obvious figure under normal activities.

Contrast spotlights (although this comparison is not reasonable, just want to say that the shadow of the working surface is relatively large interference)

If it’s a grade, it’s a nine. It is difficult to achieve this effect at a thickness of less than 2cm.

Two, light source quality

Test conditions:

Simulated darkroom, illuminometer reading 0.1,

Test distance: the probe is about 1.9m away from the light source, close to the height from the working face to the lamp used at home.

Spectra of 4000K lipro ceiling lamp:

The figure below is 4000K spectrum of a Ra95 high-display lamp:

Measurement is the same equipment, the same environment, Lipro spectral continuity is better, blue light content ratio is much lower, relatively excellent.

Color temperature

The color temperature range is 3000-4000K. I really agree with this tonality and non-conformity. Three-shift color mixing can be arranged with wall switch, the default is 3000-3500-4000 with three gears, which can be customized in the APP.

The official standard is 4000K, the actual measurement is 4170K, the official standard is 3000K, the actual measurement is 3174K, there is a certain deviation, in the acceptable range.

CRI details (4000K)

Ra97.9, R9 is also above 95, R15 is close to 100, absolutely friendly to facial makeup, very good.

Rg-Rf

Rg: 101.2, Rf: 97.3, both approaching 100, excellent level.

Color tolerance

Compared with excellent spectrum, color rendering index, color tolerance is slightly inferior. At 4000K, the color tolerance is 6.3SDCM, just reaching the pass line, and at 3000K, it is 4.6SDCM.

Intensity of illumination

Under the peak brightness, the illumination is 236 when the distance is 1.9m, which meets the requirement of daily lighting without pressure.

Summary: whole say, illuminant quality belongs to excellent level.

Luminous flux and power

The 40W whole lamp power is actually measured 38.9W, the official labeled luminous flux is 2600LM, the light efficiency per watt is not high, the normal moment, the power factor is above 0.9, very good.

Iii. Control experience and technology

Since there is no wearable device or voice device for ceiling lighting, we can only install an APP to feel the experience, with a minimalist interface, no advertising and no tedious operation.

Support 1%-100% stepless adjustment, the smoothness of adjustment is very good, even from the highest brightness to the lowest brightness, but also uniform change, there is no “sudden jump” feeling, this is very well done.

Joke: The APP only supports android version at present, and the version I am currently using does not support infinite color palette, so I can only choose color temperature. The ios version is not available yet, so it is not friendly to Apple users at present. The official said that the ios version will be available in July, so I am looking forward to it.

Appearance process

From the point of view of lamps and lanterns, surface treatment and joint treatment are quite in place, and no obvious defects have been found.

The quick installation design greatly optimized the installation experience, even without a professional electrician can easily start the installation, my entire installation took about 2 minutes, buckle wiring without electrical tape.

packaging

Very tight, even feel a little too much packaging, paper packaging two layers, foam, foam cotton everything.

Although a little waste of material, but transportation to a lot of insurance, see how to choose.

Zong:

See out, Lipro ceiling lamp in the process design, light source quality, materials and materials have spent a lot of thoughts, which is worthy of being loaded seriously do lamp, from the lamp positioning and experience is an excellent level, competitive products are less, from the control experience, soft control is soft.

Price from ￥499 to 999, suitable for people who have a certain pursuit of lighting.
