In recent years, with the rapid development of intelligent hardware, the home projection market is showing a blowout trend, of course, the competition is becoming increasingly fierce.

Brightness has always been a big problem for household projection. Especially for portable projection, due to the limitation of the size of the fuselage, the brightness is often unsatisfactory; Another important reason that affects brightness is the type of light source. At present, in the field of home projection, many manufacturers have chosen LED light sources, but due to the limitations of objective factors, LED light sources often have great limitations in brightness.

At this point, the laser source becomes a choice to improve the brightness problem; Today, the author brings you the experience of a portable laser projection - Guangfeng A1 laser projection. Let's see if this compact laser micro projection can bring us a different viewing experience.

1、 Packaging and Unpacking

The package of Guangfeng A1 laser projection uses black as the main color, which gives a very calm and delicate feeling; The front of the package is printed with the words of product model "A1", and the back is printed with the specific model, specification, serial number and other information of the product. The side of the package is printed with brand logo, product energy consumption level and other information.

Open the package of light peak A1 up and down, and we can directly see the projection host. The color of space gray is adopted, which gives us a sense of texture at first sight; In order to facilitate the removal of projection, transparent and easy to pull stickers are added to the projection side; We took out all the accessories, and it can be seen that the standard configuration of Guangfeng A1 is: projection host, power adapter, product manual, three guarantees certificate, certificate of conformity, two No. 7 batteries, and remote control.

For users who use projection for the first time, it is recommended to carefully read the accompanying manual, which has a more detailed introduction to the product, so that they can get started quickly.

The remote control of Guangfeng A1 uses two No. 7 batteries to provide power. The overall shape of the remote control is small and smooth, and the feel is good. The remote control is designed with ten buttons, which can achieve comprehensive control of projection.

The power adapter is equipped with a cable tie to facilitate the storage of power cables; The adaptive plug adopts two plugs, which can effectively save the space of the patch panel.

2、 Appearance details of Guangfeng A1

The light peak A1 uses space grey as the main color, and the fuselage is made of all metal materials, with a size of about 20.7cm * 13cm * 2.4cm. It looks very compact on the whole. In addition to the color matching of space grey, it gives a low-key and delicate look. The front of the fuselage is very simple, with only the highlighted logo image of the brand, which is very textured. The four corners of the back of the machine body are respectively designed with an anti-skid foot pad, which can effectively prevent the bottom of the machine from being worn out accidentally.

The front of the product is successively designed with a fishgill type heat dissipation window, a rotary switch, an imaging lens and a reflector mounting hole from left to right; After the power supply is connected, turn on the rotary switch, and the projection can start automatically; Turn off the rotary switch, and the projection will be turned off automatically. At the same time, the rotary switch can also be used as a small bracket, which is very practical.

The left side of the fuselage is the cooling air inlet and the power indicator, which will light up when the power is turned on; The right side of the fuselage is the cooling air inlet and the external horn hole.

The optical peak A1 projection has designed all the interfaces at the rear, from left to right, including the power jack, USB2.0 interface, USB3.0 interface, HDMI interface, reset key, and headphone jack. The existence of two USB interfaces facilitates the use of USB flash disk or mobile hard disk to access data.

3、 Experience sharing of actual projection effect

The brightness data officially given by Optical Peak A1 Laser Projection is 700ANSI lumens, which is quite good on such a small body. In addition, Optical Peak A1 also supports automatic trapezoidal correction, which is convenient for users. What about the brightness projection effect of 700ANSI lumens? Let's have a look.

At about two meters, we will test the projection effect. The time is about 8:00 p.m., and turn off the indoor lights.

From the projection sample above, we can see that the light peak A1 has a very good effect on image restoration. At the same time, in terms of color performance, the red, blue and green light colors are more plump, and have good permeability. It is more visually pleasing, and the details are preserved well.

Next, we will use the light peak A1 to experience the effect of watching movies.

When the lights are turned off at night, the projection effect of Guangfeng A1 can be said to make the author feel very excellent. The picture is clean, the details are well preserved, and the overall feeling of the picture is very good. Moreover, even when the light is turned on at night, the projection effect of the picture is good. It can be seen that the laser light source has significantly improved the brightness.

Projection effect when lights are turned off at night

Comparison of the projection effect between turning off the lights and turning on the lights at night (on the same scene, turning off the lights below)

Let's take a look at the projection effect of not pulling the curtains during the day.

The projection effect is good when the curtains are not pulled in the daytime and the lights are not turned off at night, but the picture is still very clear. The overall projection performance has greater advantages compared with the same type of projection. At the same time, as a laser light source projection, its service life can reach 60000 hours, that is to say, if it is used continuously for 6 hours a day, it can be used for about 27 years, and its service life is not comparable to that of ordinary LED light source projection.

4、 System UI experience sharing

The overall design of the system interface of Optical Peak A1 is flat and easy to use. With the combination of 2G operation storage and 8G storage, the system experience is very smooth in actual use. After several days of experience, the author did not encounter any phenomenon of "stuck".

When starting up and using Lightpeak A1 for the first time, the system will have some prompt interfaces, such as instructions for remote control, language selection, etc., which can be selected according to your own actual situation.

The system interface is divided into two large areas, one is the menu bar area on the left and the other is the display area of the main interface. The overall interface is easy to understand and use.

The menu bar area on the left includes settings, message alerts, screen projection, file management and other functions. Among them, in "Settings", you can make all-round personalized settings for network connection and projection. Projection can be set in network settings for wireless WIFI connection.

In projection settings, we can select the focus, trapezoid correction, image mode, etc. of projection according to our own needs.

In the general settings, we can see some basic information of the projection, and make some basic settings. For the desktop version, we can choose the entertainment version (the system default) or the business version. The business version relatively adjusts some modules commonly used in work to prominent positions.

Guangfeng A1 text input interface, the overall interface display design can ensure a good input experience.

Let's take a look at the main interface display area (entertainment version). The display area of the main interface includes six modules: online video, online music, online games, app store, My Favorites, and all applications.
