"In the past holiday, the spring was beautiful, and everyone went out one after another. Naturally, all kinds of digital products were carried with them, and the micro projector was a new trend product.
Compared with ordinary home projectors, micro projectors have the characteristics of small volume, easy to carry, and some have their own batteries. They can be easily put in. They are a sharp weapon for traveling and office. They can be enjoyed in the new era, whether they are enjoying blockbusters in the car, camping in the wild, sharing the stars and chasing dramas. At the same time, due to its small size, heat dissipation and projection brightness are also its weaknesses.
Science and technology are developing and life is improving. With the emergence of new technology and the improvement of technology, the micro projector is also improving. I was lucky to experience a new Le box-t micro projector launched by vez. I would like to share with you how to perform and progress in these aspects.
[portability]
It can be seen that it is a square box surrounded by champagne gold, which is commonly known as tuhaojin. Behind it are some interfaces, which looks elegant and compact as a whole.
Maybe the Le box-t you see on the computer seems quite large, but in fact it is very small. The box is only a little more than 9 cm long, and its volume is even smaller than most Internet boxes.
We often say that "the palm can be fully grasped". This word is also quite suitable for Le box-t. you can easily hold it in your hand.
Weigh the projector. It's only 173 grams. It's very light and easy to carry. You can put it in your pocket.
Le box-t is small, concise and easy to carry.
[functional interface and appearance workmanship]
Although the box is small, there are many interfaces. On the front of the projector, you can see the position of the lens on one side, and there are many heat dissipation fences next to it.
On the adjacent side of the lens, there is a black runner at the front end for focusing, and a square sound hole on the side.
On the other side are the start button, reset hole and heat dissipation fence.
On the back is the charging hole, charging indicator, standard USB interface, TF card interface and audio output port.
Le box-t has complete interfaces, but there is no HDMI interface, so how to connect to the device display? Let's see later.
Jiang Le box-t turned over and saw that the bottom was also all black, surrounded by four rubber pads.
We see its corners come out very beautiful, with wonderful arc and luster. According to the introduction, this is the use of CNC diamond trimming technology. At the same time, I also noticed that there is no gap in the metal fuselage. According to the official website, aviation aluminum plate is used for one-time stamping, which gives people the feeling of extraordinary quality.
Le box-t champagne gold all metal body color shows noble quality, exquisite workmanship and rich interfaces.
[accessories]
The components of Le box-t lie quietly in three black boxes at the bottom.
Remote control, tripod, telescopic support, base, battery. In other words, compared with the compact size of Tongle box-t, this small remote control also seems too big.
Instructions, charger, charging line. Note that the charging cable is used here instead of the power cable, because the Le box-t itself has a lithium battery, which can be played even if it is not connected to the power supply. It's nice to think of such a small box with batteries.
The charger is foldable for easy storage.
The remote control uses two No. 7 batteries for power supply. In fact, the function looks very simple. Why not make it smaller?
Le box accessories are quite complete. It would be better to have a storage box or protective cover, which can protect the lens. When you go out and carry it, you are worried about whether the lens will be polluted and damaged.
[installation and placement]
If the base is retractable, the Le box-t can be stuck. At the same time, there are screw holes on the base to install a tripod.
The side of the base also has a screw hole, so the projector can also be placed vertically.
The screw holes on the base are standard, so the tripod of SLR can also be used to fix the projector.
The base supports horizontal and vertical placement. In terms of appearance, although the base is good alone, it works with the projector, which feels that it lowers the grade and beauty of the projector, which is not very coordinated. Moreover, after the base is stuck, it will always block some heat dissipation fences or speaker openings, which makes people feel that it is not like a product designed by a company.
[display effect]
Due to its small size, the micro projector is limited by the reasons of devices and heat dissipation, and the brightness of projection is not as high as that of ordinary projectors. In the past, micro projectors can only be used at night because of the projection brightness. Now, due to the improvement of technology, the situation has been improved to some extent. Let's see how Le box-t performs in this regard.
Because the effect of projection is also related to distance, the farther the distance, the weaker the brightness of the corresponding projected picture. At the same time, the intensity of ambient light also affects the projection effect. Therefore, let's take a look at the projection screen display effect of Le box-t portable projector at different distances and different ambient light. At the same time, because the portable projector emphasizes portability, the interface of the projection screen is an ordinary wall to reflect the real use environment.
In recent days, the weather is fine and the indoor environment is very bright, so the environment is divided into sunny noon, sunny evening, cloudy noon and evening.
The pictures are real pictures, showing different effects as much as possible. However, due to factors such as monitors and cameras, the display may be different from the actual effects. I hope you will understand.
[night]
The first is the picture directly projected onto the white paperboard at a distance of about 40 cm. The picture is clear, beautiful and has a good effect.
The picture of the film and television play is also very clear.
The living room is about 2.5 meters away from the wall. The display effect and color are also normal, which makes it feel like a cinema.
On the ceramic tile in the bathroom, the distance is about 1m, and the picture is very clear.
Projected onto the wooden door of the room, the distance is about 90 cm, and the effect is also very good.
The ceiling of the bedroom roof is about 2 meters away, and the brightness is brighter than the distance of 2.5.
Projected onto the sky blue wall 1.5 meters away, the effect is also very good. If there is no contrast, it doesn't look like it is on the blue wall.
In short, under the condition of low illumination at night and within the viewing range of less than 2m, Le box-t shows a good display effect in the brightness and color of the projected picture.
[sunny evening / cloudy day]
At this time, the sky is a little dark, and the general effect is similar to ordinary cloudy days. 40 cm is put in close range, and the picture quality is no different from that at night.
The effect is similar when playing movies.
Projected onto the tiles in the bathroom, probably due to the better reflection of the tiles, the brightness effect is still good.
[sunny noon]
Let's look at the performance of Le box-t around 12 noon when the weather is fine, the indoor light is sufficient and very bright. 40 cm projection. Due to the close distance, although the surrounding light is strong, the color is also quite good.
As for film and television viewing, the data are also in a more normal range.
In short, in the case of strong brightness at noon, the distance of more than 2m is not viewable, and it can be viewed within 1m, but the color will be affected.
Through the comparison of projection effects and real shooting effects under the first three different ambient lights, the projection effect of Le box-t has undoubtedly made considerable improvement and progress over the previous micro projection, changing the situation that micro projection can only be used at night. This is because Le box-t adopts advanced Texas Instruments DLP technology to provide 16.7 million colors and 256 gray levels to ensure fine, natural and colorful pictures. Using German OSRAM LED light source, the service life is up to 30000 hours.
[office application effect]
In addition to home use, office applications are also places where micro investment can be used. It's much more convenient to explain to customers outside. It's also easy for many people to watch. It's especially suitable for occasions with few people. In this way, it can be projected and viewed without occupying the conference room or using a special projector. Compared with watching movies and TV at home, office applications are mainly text and charts.
In normal weather, the distance of light projected on the whiteboard is about 2 meters. We can see that the characters can be recognized normally. Due to the strong light, the characters are gray.
When the curtain is closed, the words are much clearer. It can be seen that Le box-t is no problem for office applications.
Even on the partition cloth of the office, even if it is gray, you can see the text. Because it is not film and television, you don't care about some color deviations.
[other of display effect]
We often say that the projection is a large screen, which has the feeling of cinema. How large can the Le box-t project? The distance during projection was mentioned earlier, so the corresponding screen size. Here, the distance is 50 cm, and the screen is about 20 inches; At a distance of 1 meter, the screen is about 38 inch screen, and at a distance of 2 meters, the screen is about 71 inch screen.
At the same time, from the front picture, we can see that some of the projected pictures are not squares, but trapezoids. As we all know, when the projection lens is not perpendicular to the projected surface, trapezoid will naturally appear. Therefore, there is a projector trapezoidal correction technology. Some support up-down correction, others support up-down and left-right correction. In this way, the position of the projector will be much more flexible.
Unfortunately, Le box-t does not support trapezoidal correction, which undoubtedly makes it less convenient to use.
We saw that there is a focusing knob. In actual use, it is not easy to focus accurately when the distance is large. If there is automatic focusing, it would be good.
In addition, for convenience, we don't want to carry the projection cloth with us, so the projected wall may not be white. Some conventional projectors have background color settings, and several background colors can be selected. It's also a pity that Le box-t didn't.
[performance and film and television resources]
Different from conventional projectors in the past, Le box-t has an intelligent system, which can realize various functions without external playback equipment. Le box-t adopts rockchip A7 chip, with 1GB running memory and 8GB space, and supports 1080p and h.265 video decoding.
After startup, the default screen is Metro style. We see that there are various functions.
As an intelligent system, the most useful thing is to integrate various resources. Let's watch the movie on demand in the lower left corner and go in and have a look.
There is a simple prompt after you go in. Take a closer look, it turns out that cibn resources are integrated into the projector.
All kinds of resources are available here, so it's needless to elaborate. In other words, Le box-t has a built-in network player, which can play a large number of Internet Film and television resources without external equipment. Fashion hot spots, film and television chase dramas and so on.
As we saw earlier, Le box-t has USB interface and TF card interface. After it is plugged in, it will be prompted automatically.
You can also play internal resources.
Playing resources supporting h. 265 can get better picture performance.
Not only local resources, but also network resources can be accessed through the built-in file manager app.
You can also play local network video. The advantage is that you don't need to copy files to USB flash disk or TF card, but access them directly through the network, which saves time and is convenient to use.
[functions and settings]
To realize network access, you must need a network interface. Le box-t does not have a wired network interface, so the network is realized through wireless WiFi.
In the settings, you can set various wireless connections or wireless hotspots. Unfortunately, Le box-t only supports 2.5GHz wireless single frequency instead of 2.4GHz and 5GHz dual frequency.
In the display, you can adjust the brightness, color temperature, projection mode, font size and screen zoom.
For example, color temperature adjustment is divided into cold color temperature, standard color temperature and warm color temperature, and different picture effects can be obtained.
The brightness adjustment is divided into five gears, and the default is the middle gear. Even if it is adjusted to the maximum, the middle gear will be set by default every time the projector is restarted. So if the projection brightness is not enough, try adjusting the high gear.
Le box-t has its own lithium battery, which can be viewed without external power supply. According to the use of several days, it can be used for 2 hours with full power. The current capacity and usage time of the battery can be seen in the settings.
The music box-t comes with its own sound, and the effect is specially designed. Although the music box-t is small, the sound effect is still good, which is stronger than the horn of the conventional display. The sound is clear, the treble is loud, and the echo effect is very good.
Of course, generally speaking, the speaker still belongs to the standard level, so you can also use the built-in Bluetooth of Le box-t and connect it to the Bluetooth speaker for playback.
[wireless on the same screen]
Le box-t is not equipped with HDMI interface, so how to make external devices use projectors to project pictures? Then it is achieved through wireless WiFi.
For Android system, select the same Android screen on the interface, then turn on the WiFi screen on the mobile phone, and then agree with Le box-t.
Using the same screen function, the most useful thing is to play games in addition to watching movies and TV. Try out the popular king glory. The mobile phone is almost synchronized with the projector screen.
Apple phones only need to use the airplay function, which is also very convenient.
As the most used Windows system computer, it is often used on business trips, but it does not have the expected effect. According to the instructions
