Have you ever stared at your own ceiling in a daze? Thinking about the magical device that can be used as the main light and play videos, where should I install it so that it will not be abrupt. To be honest, this problem has troubled many newbies who are new to smart homes - they are installed too far from the middle and are afraid of being pressed high, and installing against the wall will affect the viewing effect, not to mention hidden minefields such as heat dissipation and wiring.

​​Three major misunderstandings in installation location​​
I have visited more than 20 installation sites and found that novices often make these mistakes:

1. ​​Obsessive-compulsive disorder in the middle​ ​: It must be installed in the center of the room, but when the person stands directly under the screen, there will be a clear heat feeling above his head (the measured temperature difference is up to 8℃)
2. ​​Save space traps on top​ ​: Put the display close to the ceiling, and the color deviation rate soared to 12% after three months, far exceeding the industry's 5% warning line
3. ​​Single point load-bearing adventure​ ​: Use expansion screws to fix the concrete roof directly, and there is a risk of falling off when the floor slab vibrates.

There is a very typical case: an owner installed the equipment in the center of the children's room, but the child always said "there is something baking hair on his head." Later, the test found that​ ​When the heat dissipation hole is only 80cm away from the human head, the surface temperature of the equipment must be controlled below 40℃.​ ​——Ninety percent of installers will not let you know about this detail.

​​Four golden rules for scientific site selection​​
After actual testing by engineers, you should write down these four parameters with a notebook:

• ​​Range of sight formula​ ​: Screen size (inches) × 2.5 = optimal viewing distance (cm), for example, 137cm of viewing space is required for 55-inch screen
• ​​Heat dissipation space​ ​: Keep at least 15cm of ventilation layer from the ceiling, and a flow diversion groove must be installed behind it
• ​​Brightness adaptation​ ​: According to the window orientation, it is recommended to use 4000cd/m² or above models in Xisan room.
• ​​Load bearing reinforcement​ ​: 6 stress points must be installed per square meter, so don’t believe in the saying “three screws are enough”

Here is a cold knowledge you may not know:​ ​Devices with intelligent light sensing chips can automatically adjust brightness according to ambient light, saving 37% power than fixed brightness models​ ​. Just like the principle that your mobile phone screen will brighten and darken according to the environment, it is just that the technical requirements are higher when used in ceiling lights.

​​Ask and answer core questions​​
Q: Why does the master always say that "it is better to install it in a suspended ceiling"?
A: This is actually a change of concept! The ceiling installation can indeed hide cables, but two things to note:

1. Ultra-thin models with a thickness of ≤8cm must be selected. Stopping ordinary models into the ceiling will cause overheating.
2. The maintenance port should be left at 1/3 of the diagonal line of the screen. It is best to use the disassembly and assembly tools at this location.

Q: How to judge whether your floor slab can be installed?
A: Teach you a method: use a screwdriver to drill holes at the predetermined position. If the spacing between the drilled steel bars is less than 15cm, congratulations on installing them directly ； If there is no steel bar when drilling 5cm, please install a load-bearing support immediately. Of course, the safest thing is to find a professional structural engineer to inspect, so don’t save this money.

​​The secrets that manufacturers won't tell​​
Once I visited the production line and accidentally discovered an amazing fact:​ ​Models that support HDR10+ must be matched with a dedicated fixture to give full play to the image quality advantages.​ ​. Because the micro vibration of ordinary brackets will cause misjudgment of the image processing chip, it is like using a sports car engine to fit a tricycle chassis.

Let me talk about the industry's unspoken rules: many devices that claim to be "ultra-thin" actually use the driver power supply to be externally installed. This design will add an ugly adapter box. Remember to ask the master to hide the power box in the air conditioner maintenance port or curtain box when installing it.

Recently I saw a very interesting data: In a smart apartment project in Tokyo, the engineer installed the display screen 1.2 meters away from the balcony door. This not only avoids direct sunlight, but also uses sliding doors to form natural air ducts, so that the surface temperature of the equipment will drop by 11°C in summer. Sure enough, masters are among the people! So, if you install this thing, you really can't listen to the merchants. Thinking about the house structure yourself is better than anything else.
