With the development of smart home industry, the popularity of intelligent lighting applications is rapidly, more and more lighting products with all kinds of intelligent module, clothed in a "smart" lamps and lanterns.

Throughout the intelligent lighting market now, we can find a lot of lighting products, can through the phone APP to open and close and adjust the brightness and color temperature. The intelligent application, invariably leave the "control" two words, just had on the lamps and lanterns can realize the function of the operation, ported to mobile phone remote control. Strictly speaking, this is a "smart", truly intelligent lighting products, should be able to get rid of the factors of "control", and according to the preset conditions, give the user to provide the most suitable light automatically.

In may this year, philips ZhiRui lamps in millet shopping online, it is a by philips and millet jointly launched the desk lamp that shield an eye. According to official data is introduced: this is a bright light, mobile phone camera and light sensor, optical signal collection and processing, to calculate the environmental brightness, light efficiency is optimized through the "light" calibration algorithm to automatically help you set-up the right brightness, let you no longer worry for too bright and too dark.

At the same time, love Elamp under the desk lamp that shield an eye looking brand also in jingdong the raise is launched. Elamp built-in intelligent chip, can automatically detect the ambient light brightness and brightness stepless adjustment, to ensure that the desktop illumination constant, effective protect his eyes from the light is too dark, too bright or too big to produce visual fatigue.

From the point of functional description, ZhiRui and Elamp are claimed to be able to automatically adjust the brightness, so as to protect the user's eyes. Because no other Tmall and jingdong which has the function of automatic dimmer lamp, so today specially for ZhiRui Elamp and conduct a comprehensive assessment.

This assessment will be conducted in line with the attitude of objective and neutral, respectively from the design, operation, and optical properties, intelligent application, additional application comparing these five aspects.

A, design,

1, appearance design.

ZhiRui is one of the more popular three-stage folding desk lamp, plastic material, hard straight lines, color is a commonly used white millet. Elamp appearance belongs to a character arc shape, silver metal texture, surface plating processing. About the same size as ZhiRui unfolds and Elamp.

From design point of view, each has his strong point.

2, the structure design.

ZhiRui adopted double rotor design, rotating shaft adjust the irradiation range, but the rotation a bit tight, one hand it is difficult to adjust their point of view, and the lamp holder can rotate around. Elamp lamp is fixed, is a completely unable to adjust the desk lamp of, to adjust the lighting position need to move the whole lamp.

From the point of structure, ZhiRui humanness is a bit high.

3, process details.

ZhiRui process and details in the philips products of high quality, of the components and surface processing, all shows the characteristics of the world's first brand.

In contrast, Elamp have some room to improve.

Second, the operating

1, the operation.

ZhiRui and Elamp are touch operation. ZhiRui have touch the base of the buttons and indicator lights, from left to right, respectively, power supply, 1-4 brightness, lightly touching can open to turn off the lights and adjust the brightness, but light is no related icon labeled, for the first time to use need to be familiar with. Elamp base on the touch screen only two touch key, is the power button at the bottom right, next to a different gear target value of the intensity of illumination of switch button. Likewise, if you don't see the directions, understanding the meaning of the three groups of digital Elamp touch screen will be a little difficult.

On the design of the operation, slightly better than Elamp ZhiRui.

Third, optical performance

1, the color temperature.

Through professional measuring instrument to detect, ZhiRui 4108 k color temperature, color tolerance is more than 7 SCDM, and Elamp 3956 k color temperature, color 3 SCDM tolerance.

According to the American national standards institute chromaticity requirements "solid state lighting products, LED products color tolerance should be less than 7 SCDM, ZhiRui and failed to meet requirements.

2, color rendering.

The same test, ZhiRui shows index Ra = 79, R9 = 3. While Elamp color rendering index Ra = 87, of which the R9 = 41. In accordance with the technical specification for visual operation desk lamp certification, desk lamp and color rendering index should be not less than 80 R9 should be greater than zero.

ZhiRui failed to meet the requirements, in both Elamp have better color rendering.

3, the maximum intensity of illumination.

Full power operation, ZhiRui lamp light source right center of the maximum value of 872 lux, Elamp maximum of 861 lux, both difference is not big. (note: both light source distance desktop distance is 38 cm)

4, the uniformity of illumination.

The normal service condition, the light source of lamps and lanterns below center, and center distance of 10 cm, 20 cm, 30 cm position of illuminance value below. In each of the first axis of the intensity of illumination, falling ZhiRui proportion is bigger than Elamp, therefore Elamp relatively better lighting uniformity.

Fourth, intelligent applications

Both the intelligent application of desk lamp, the main selling point when external publicity, and this is the main content.

1, the use environment.

ZhiRui is a can connect the desk lamp of WIFI, its intelligent application must be in WIFI environment can be achieved, Elamp without any restrictions.

2, preparation before use.

Elamp without connecting mobile or WIFI, plug-in electric automation operation. Using ZhiRui need to install the APP, the rice may feel installation and connection of step is:

1, intelligent household APP install millet;

2, search, add ZhiRui lamps;

3, a lamp installation ZhiRui APP;

4, to open the APP connection ZhiRui;

5, input the WIFI password make ZhiRui connected wi-fi.

3, metering principle.

ZhiRui itself without metering function, need through the phone APP software, mobile phone camera to measure. Elamp base with photometric sensors, the metering technology and professional illumination meter, same ZhiRui compared more accurate.

4, dimmer mode.

Elamp providing 7 file target value of illumination for the user to select, after setting, Elamp kept testing environment changes in the light, and automatic stepless adjusting their brightness, to ensure that the desktop actual illumination constant. This adjustment is dynamic, automatic, stepless, and desktop mixing intensity of illumination this result oriented.

While ZhiRui dimming is divided into four different scenarios in the APP, and 0-100% of stepless adjustable light. After adjusting the manual alone, the luminous intensity of lamps and lanterns is fixed. When the environment changes of light, the brightness of the ZhiRui cannot be changed.

5, degree of intelligence.

Elamp can automatically adjust its brightness, and always give the user a constant lighting effects, don't need human intervention. ZhiRui also claimed that the suitable brightness, automatic calibration to avoid the light too bright and too dark. Calibration is automatically, but the need for human place your phone desk lamp directly, and click on run calibration program. And calibration is a one time, when the ambient light change, need to adjust again.

We believe that ZhiRui this feature is not very smart. As for other intelligent applications, in addition to the regular eye reminder more intimate, other application practicability is not high.

Five, the additional functionality

1, the additional functionality.

Backend ZhiRui base provides a USB interface convenient mobile phone charging, while Elamp without any additional features.

To sum up:

ZhiRui and Elamp can claim to adapt to changes in ambient light and automatically adjust the brightness, for users provide a more appropriate illumination, in order to protect users' eyes.

ZhiRui and Elamp have distinguishing feature each, in appearance and structure design in the process details, touch keys and additional features, slightly better than Elamp ZhiRui.

Optical performance, in addition to the maximum intensity of illumination, other optical performance is better than the ZhiRui Elamp.

On the core of intelligent application, is not ZhiRui, as outlined in the publicity materials so "smart", require the use of mobile phones and artificial initiator, and light is a one-off. Elamp is full automatic operation, automatic brightness adjustment to adapt to the environment light. Intelligent applications, Elamp triumph.
