Xiao Yi, a designer from Baidu Yashe Decoration, told reporters that the choice of floor materials in the living room and bedroom is very important. The choice of floor or floor tile depends mainly on the size of the room. Generally, the small apartment below 100 square meters is more suitable for selecting the floor, reflecting the warm atmosphere of the room, and the floor tile is more suitable for some living rooms with larger space to highlight the feeling of the atmosphere. Xiao designer also reminded our landlord friends that if there is a family of children, avoid installing tatami, the harmful gas emitted by the material will generally settle in the interval of about 30 cm above the ground, and the child will use tatami for a long time. Brain development has an impact. Guest bedroom decoration, the layout is very important, happy space decoration: Duna designer Duna designer from the festive space decoration told reporters that the living room layout is very important. First, consider dividing the living room into several areas, and then decide the shape. Then we should consider the placement and height of the home. Finally, we recommend the lighting of the living room and The color is consistent and it is recommended to be colder. In terms of the bedroom, the key to the layout is to consider the size, width, and orientation of the bed to avoid congested bedroom space. It is recommended to use a slightly lighter color in the color, the light source is warmer, and it is better to embellish some auxiliary light sources. Functional partitioning makes the guest bedroom more practical and innovative thinking decoration: Tan Cong designer Tan Cong, who is decorated with innovative thinking, told reporters that most of the living room and dining room are now integrated, so functional partitions, dining areas, rest areas, and aisles are required to be clearly defined. The living room should pay attention to the setting of traffic flow lines and reach the kitchen. , the bathroom, do not detour between the bedrooms. In the decoration of the living room, the color of the latex paint should be selected according to the orientation of the house. According to the different orientations and different light angles, it is better to set the color tone of the living room with the color of the latex paint. He also said that the lighting of the bedroom is very important. If it is only used for sleeping, it is recommended to use a soft light source. If it is a combination of work and study when sleeping and working, it is recommended to use auxiliary light source, table lamp and wall lamp. In the application process of high-power LED products and devices, heat dissipation, electrostatic protection, and welding have a great influence on their characteristics, and they need to be highly valued by application-side customers.

Heat dissipation
Due to the limitation of semiconductor light-emitting diode chip technology, the photoelectric conversion efficiency of LEDs needs to be improved, especially for high-power LEDs. Because of their higher power, about 60% of the electrical energy will be released as heat (with the development of semiconductor technology, The photoelectric conversion efficiency will gradually increase), which requires end customers to do a good job of heat dissipation when applying high-power LED products to ensure the normal operation of high-power LED products.
1. Heat sink requirements.
Appearance and material: If the sealing requirements of the finished product are not high, it can directly convection with the outside air environment. It is recommended to use finned aluminum or copper heat sinks.
2. Effective heat dissipation surface area:
For 1W high-power LED white light (other colors are basically the same), it is recommended that the total effective heat dissipation surface area of the heat sink is ≥50-60 square centimeters. For 3W products, it is recommended that the total effective heat dissipation surface area of the heat sink is ≥150 square centimeters. Higher power depends on the situation and test results. Try to ensure that the temperature of the heat sink does not exceed 60°C.
3. connection method:
When connecting the high-power LED substrate and the heat sink, please ensure that the two contact surfaces are flat and in good contact. In order to strengthen the combination of the two contact surfaces, it is recommended to coat the bottom of the LED substrate or the surface of the heat sink with a layer of thermal grease (thermal conductivity of thermal grease) ≥3.0W/mk), thermally conductive silicone grease shall be applied evenly and in an appropriate amount, and then fixed with screws.
welding
1. When soldering, please note that it is best to choose a constant temperature soldering iron, the soldering temperature is below 260℃, and the contact time between the soldering iron and the LED pad should not exceed 3S;
2. For high-power LEDs encapsulated by silicone, the maximum heat-resistant temperature of silicone is 180°C, so the soldering temperature of the LED should not exceed 170°C. Use low-temperature soldering iron and low-temperature solder paste (wire) for soldering, and the soldering iron is in contact with the LED pad at one time The time does not exceed 3S.
