For the desk lamp, a daily household product, you can often see its shadow near the bedroom, living room, study and computer. Compared with the promotion and popularization of various glasses, monitors, televisions and other devices that focus on eye protection and anti blue light in the past two years, desk lamps that focus on non flashing screens, eye protection, and anti blue light have been quietly embedded in real life, not only for growing children and adolescents, but also for people who often need to work overtime and prefer reading at night. However, there are many kinds of eye protection lamps on the market, and the price ranges from tens of yuan to thousands of yuan. The actual lighting and eye protection capabilities vary greatly, and it will be difficult to purchase. So what kind of eye protection lamp is it? Eye protection lamp is simply a desk lamp that can protect vision. In depth, it can make the lamp emit light with characteristics close to natural light, and at the same time, the light will not harm the human eye, resulting in eye discomfort or even reduced vision.

For this BenQ WiT e-Reading desk lamp, in addition to the anti blue light, non flashing screen, wide color temperature area, manual stepless color adjustment, and the minimalist design style, it also has the functions of adjustable angle of both arms and lampshade, wide lighting range, and one button eye protection adjustment.

Let's learn more about it.

Minimal design style The material of lamp arm is fine and easy to install

BenQ WiT is divided into two parts, one is the base, and the other is the part of lamp arm and light source. One of the highlights of the design is the two-part design of the lamp arm, that is, the double arm design. The thick and heavy zinc alloy material is used to improve the firmness of the lamp arm. The two arms can rotate at different angles, but the adjustable range of the upper arm is much higher than that of the lower arm. The connection between the lower arm and the base can rotate horizontally.

There are reserved power lines exposed at the connection of both arms, so as to ensure the normal and free angle adjustment of both arms. The light arm adopts a square appearance design, which looks quite standard. The material is aluminum alloy, and the surface is treated by spraying technology, which plays a anti-skid function.

The biggest practicability of BenQ WiT double arm design is that it can adjust the height and angle to adapt to various desktop sizes, and adjust the exposure area according to the actual situation. The height can be adjusted from 31cm to 80cm.

The hexagon screw design is adopted at the connection of the two arms, which is somewhat tight and requires force for adjustment. However, no corresponding tools are provided with the package, which makes it inconvenient to adjust the tightness.

Most of the power cables adopt the hidden wiring design, which is routed through the groove on the inside of the lamp arm, making the lamp arm look clean.

The second highlight is the touch switch design of the big circle. Compared with the smart lights that support tapping switches, the advantages of touch switch design are more responsive and more convenient to operate. The white shuttle knob on the top is the multi-functional physical key of BenQ WiT, and the operation mode is click and rotate. The so-called multi-function is: first, click to turn on the light when the light is off, but it does not support the function of clicking to turn off the light; Second, when the light is on, click to switch the color temperature adjustment function; Third, the function of stepless brightness adjustment can be realized by rotating, and the switching of different color temperatures can be realized at the same time. The lamp head is also made of aluminum alloy, but it is equipped with frosted spraying technology, which makes it look more textured.

BenQ WiT supports the function of one button intelligent adjustment, that is, intelligent reading mode, which can be started by pressing the ring for 2 seconds. The advantage is that it can intelligently judge the light and color temperature suitable for reading by automatically detecting the brightness of the surrounding environment.

For the principle of detection, after a round of inspection, the WiT should be the element at the bottom of the lampshade, that is, the built-in light sensor, to actively detect the ambient brightness, thus realizing the function of automatically adjusting the light.

When BenQ WiT successfully turns on the intelligent reading mode, a green indicator light will light up. The position of the indicator light is somewhat concealed, which is located at the connection between the ring and the lamp shade. The touch switch of this big circle is relatively convenient to operate, but because of its large area, it is easy to touch by mistake. A slight touch of the body will lead to turning off the lights. It is rarely necessary to design a long press for 3 seconds to switch on and off the machine.

The third highlight is the arc lampshade design, which is the official moon smile design, expanding the lighting range and realizing a wide lighting of 100 cm.

The lampshade is 14.45mm thick. What's the use? Improve the internal space and achieve better heat dissipation performance with aluminum alloy materials.

But is the brightness even when the illumination range is expanded? After all, a common problem with traditional desk lamps is that they are slightly bright in the middle and slightly dark on both sides. If you look directly at the light source, there is little difference in brightness. From the photos taken directly, the brightness is relatively consistent. The light source is designed as LED light bead, which is inconvenient to replace. The color temperature range is 2700K~5700K.

The following figure shows the actual shooting effect, without any modification, and only the image size is compressed. Due to the daylighting point during the SLR shooting, it seems that the central position of the screen (notebook) is slightly bright, but the brightness of the lights on both sides is not significantly dimmed. The roughly measured light range is 116cm, which can basically illuminate the desktop without dead corners.

The wide range lighting effect and uniform brightness lighting effect also provide convenience for taking pictures at night and light filling, which is more suitable for amateur players such as professional flash and soft light without light filling lamp or for taking pictures.

BenQ WiT arms support height and angle adjustment, while the lampshade part can adjust the angle. With a 360 degree spherical joint, the damping is slightly larger, which can ensure the stability of the adjusted lighting height and angle and meet the lighting needs of different scenarios. At the position of the spherical joint, BenQ WiT also reserved a section of wire, which will not pull the wire due to angle adjustment.  

This is the installation design of 360 degree metal ball. It is connected with the lampshade through a plastic slot and fixed with four screws. The plastic slot is solid and thick, so it will not break easily.

It is easy to install and use, just connect and fix the lamp arm of BenQ WiT on the base. As for the anti dazzle design, it can be inserted at any angle.

The fixation is achieved through a screw attached to the lamp arm, and there is no need to worry about overturning, because the base is heavy. However, a problem was also found during the use. That is, when the lamp arm is extended for a long time, the joint will change its center of gravity and rotate downward. While the lamp arm joint is fixed with hexagonal socket screws, BenQ does not have a helper with a standard caliber, so it is not convenient to adjust its tightness.

After fixed installation, the lamp arm can be rotated 360 degrees, and there is a slight sense of resistance when rotating.

One thing to emphasize is that the weight of the base reaches 7.6 kg, which can effectively ensure the stability of the lamp itself, including angle adjustment or height adjustment. However, there are two problems. One is that the area is large. For users with small desktops, it will be a problem to place other items on the desktop. The problem of falling during use may occur, but the probability is small. After all, the base has a weight of nearly 8 kg to ensure stability. However, there is another option for small desktop users, that is, to purchase a desk clip base.

The second problem is that the black rough counterweight is directly exposed under the base without any packaging. Although it will be easier to disassemble, it is a picky place for the beauty party. It is necessary to package to improve the overall beauty. After all, the price is also there. BenQ WiT uses DC power supply design, so there is no built-in battery. If the base is designed as a built-in rechargeable lithium battery, it may be more practical and have more use scenarios.

In the design of the power cord, the material and workmanship are more conscientious. BenQ WiT power cord is made of nylon braided wire with a length of 2m and a diameter of 5.82mm, which is wear-resistant and scratch resistant. The power cable does use a separate design, but the design of this connector is somewhat different. Why not design it as a USB interface, so that the power adapter can also be used with the USB data cable to charge other devices.

From the above introduction, BenQ WiT is simple and unique in shape. The characteristic double arm design and rotatable lampshade design realize the free adjustment of height and angle, and meet the use needs in different scenes. The smiling face lampshade with radian design greatly improves the lighting range, while the unique touch switch and the design of the endless shuttle knob bring a new operating experience. The simple and easy to use characteristics also facilitate the operation of the elderly and children.

Brightness, color temperature, one button adjustment, high brightness, wider range, intelligent reading mode, more comfortable, lampshade, excellent heat dissipation

As mentioned earlier, BenQ WiT supports 11 levels of color temperature adjustment between 2700k and 5700k, but unlike other eye protection lamps, it can achieve the function of adjusting brightness or color temperature on the selected color temperature or brightness, which is related to the LED lamp beads with two colors selected by BenQ WiT. From the following figure, it can be clearly seen that one is yellow lamp beads and the other is white lamp beads.

Let's take a look at the effect picture of light adjustment first.

Take a look at the arrangement of the interior lamp beads. There is only one row. The two types of lamp beads are arranged alternately.

The effect picture of directly shooting the lamp beads in the full black environment.

The design of this array is extremely limited in the lighting range, so it needs to use other auxiliary materials to improve. These three items are the objects in the lampshade, which are composed of inner and outer materials from left to right. They are designed as one flat and two curved. The bottom left is a smooth reflective paper, the middle is a layer of high permeability panel, and the top is the outermost panel. Through the combination of the three, the side light can be improved to a larger range, and the brightness can be uniform.

The right side of the figure below is a certain eye protection lamp in use. The lamp arm is not high, and the front and rear angle can be adjusted, but the range is very limited. Compared with the performance of the two eye protection lamps at the highest brightness, the picture is a single reverse straight out, only compressing the volume, without any revision operation. Although the two eye protection lamps were not adjusted to the same height during shooting, it can be seen from the figure that the table lamp on the right side has a relatively small lighting range but a relatively high brightness, and the lighting range also limits the placement method.

At the same time, through the contrast under the highest brightness, it can be found that the light of BenQ WiT is slightly dim, but it is soft and looks more comfortable.

For the part of blue light, it is not easy to verify without professional instruments. It can only be explained from the side that it has passed the professional blue light certification and will not appear dry, acerbity and sore eyes after two hours of use. For the flash effect, it is more convenient to verify. Take the white paper and black characters under the mobile phone preview light, and BenQ WiT will not see the wavy lines on the mobile phone screen.

For users who like reading, the one button automatic adjustment function is more practical. Figure 1 shows the automatic adjustment effect at night, and Figure 2 shows the automatic adjustment effect when the computer is turned on. The final adjusted brightness is moderate, and the warm effect makes the light look softer, which is more suitable for reading, working overtime at night, chasing anime, evaluation and office work. In terms of viewing effect, the comfort of both eyes is high, and the sense of dryness and fatigue will be significantly reduced. If people stare at the screen for a long time at night (more than 3 hours), it is necessary to purchase an eye protection monitor to better improve the effect of eye protection.

The following is the display of the automatic adjustment function. When adjusting, the light brightness will flicker, and then it will be directly adjusted to the appropriate brightness and color temperature based on the automatic detection effect. The adjustment performance is excellent, and it can be completed in 5 seconds.

Compared with the traditional desk lamp, the lighting effect will be more comfortable and comfortable, which can effectively alleviate the problem of dry and sore eyes.

We have learned about the appearance and functions. Now we will simply disassemble and comment on them to learn more about the internal workmanship. The connection between the lamp arm and the lamp cover is realized through the white four corner plastic slot. At the same time, the red and black power lines are also fixed with the lamp cover through screws, so the lamp cover and the lamp arm can be separated by disassembling six screws.

This is the part of PCB board. It is clean and tidy without problems such as twisted wire flying wire, which conforms to the style of large factory.

This is a component used to detect ambient light conditions. The specific model is unknown, and no corresponding data has been queried.

The component used in the voltage stabilizing IC is UTC 78D05AL, which is a Youshun three terminal voltage stabilizing device, and is matched with the non flickering IC technology developed by BenQ to achieve stable light source output.

On the LED controller, BenQ WiT uses the mp3398a of MPS (American Core Source System), which is commonly used in LCD, smart TV and other products. The advantage is that it supports both Analog and PWM dimming modes, so as to achieve rapid adjustment of different brightness and color temperature

Excellent heat dissipation and low power consumption

When the lamp is turned on at the highest brightness for 4 hours and 17 minutes at the ambient temperature of 26 degrees, the temperature of the LED light strip (where the lamp bead is located) detected by the infrared temperature gun is 38.7 degrees.

The surface temperature of the lampshade is 37.9 degrees, which is similar to the temperature of the lamp bead. The overall temperature is not too high, and the heat dissipation performance is excellent.  

For power consumption, the real-time power consumption under the highest brightness is 15.2W, and the minimum real-time power consumption under eye protection mode is 6.4W, which is not very high.

Eye protection lamp with simple shape and rich functions to prevent blue light from flashing

First of all, let's talk about who this eye protection lamp is suitable for. First, people with children and teenagers at home will still have more reading and writing assignments to complete at night. It is necessary to buy eye protection lamps to protect their eyesight; Second, the office workers who still need to face computers and screens for a long time at night, especially those who are engaged in research and development and design. In addition to the necessary anti blue light and non flashing screen displays, it is also necessary to purchase eye protection lamps; Third, people who have the habit of reading before bed and playing mobile tablets.

For BenQ WiT eye protection lamp, the first thing worth paying attention to is that it has passed the EU IEC/EN62471 standard certification, that is, the anti blue light certification. Don't worry about the harm of blue light; Secondly, the characteristics of wide irradiation area, soft light and non flashing screen eye protection meet the needs of reading, watching computers, playing mobile phones, etc; Finally, the design is characterized by simple shape, double arm design and rotatable lampshade design, which can adjust the height and angle freely to meet the use needs in different scenes. The suggestion for the product is to provide a table clip base for optional purchase, rather than the heavy chassis by default. As for the price of BenQ WiT, it is a little higher than the ordinary desk lamp, but there is also a reality that eye protection lamps are sold for every penny. Buying the right eye protection lamp is more practical than buying expensive and cheap eye protection lamps.
