The 3rd China Advertising and Signs Annual Conference, 2019.12.12, Qingyuan, China.

The differences between LED flexible strip & rigid strip are as follows: 1. Flexible LED strip is assembled by FPC, assembled with SMD LEDs, so that the thickness of the product is only the thickness of one coin, which does not occupy space; the general specification is 30cm long, 18 LEDs, 24 LEDs and 50cm long 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc., different users have different specifications. And can be cut at will, or can be arbitrarily extended and the illumination is not affected. The FPC material is soft and can be bent, folded and wound freely, and can be moved and stretched in three dimensions without breaking. It is suitable for use in irregular places and small spaces, and because it can be bent and wound arbitrarily, it is suitable for arbitrarily combining various patterns in advertising decoration. 2. LED rigid strips is assembled with PCB hard boards. LEDs are assembled with patch LEDs. They are also assembled with in-line LEDs. Different components are used depending on the needs. The advantage of the rigid light bar is that it is relatively easy to fix, and it is convenient to process and install; the disadvantage is that it cannot be bent at will and is not suitable for irregular places. The LED rigid light strips have 18 LEDs, 24 LEDs, 30 LEDs, 36 LEDs, 40 LEDs, etc. There are 18, 24, 36, 48 LEDs with in-line LEDs. Different specifications, both positive and side.

The seven points for LED light strip installation and daily use are as follows: 1. LED flexible light strip is an electronic precision product. Do not apply force to the product during storage, handling or shipping. Please take care when disassembling it. LED products are very sensitive to static electricity. Please pay attention to prevent static electricity during installation and use. Do not use nails or sharps to press and hold the LED surface. 2. If the DIY design is not installed by yourself, please install it by qualified technicians to prevent electric shock and short circuit. 3. Do not connect the LED light strip directly to 110V or 220V. Otherwise, the light bar will be burnt out. The light bar must be powered by a separate power supply. The power supply selection depends on the total power of the light bar and the connection length. Typically power > RGB controller (amplifier) > light bar. Monochrome does not require a controller. Power supply selection: The total power of the LED strip cannot exceed 70% of the power rating of the power supply to ensure the life of the power supply. 4. When the product is installed, the bend should be avoided just in the position of the LED or other components, so as not to cause the components to fall off and damage the product. Do not remove the surface adhesive tape when installing in advance, and compare the length position before installing. The mounting surface must be smooth, smooth, free of oil, dirt, and the surface is too rough. The unevenness will affect the adhesion and cause the product to fall off. 5. It is strongly recommended that the LED light strip be a unit of 5 meters, with the first and last positive and negative and connected to the electric mode, and the power is connected every 5 meters. This method can ensure the brightness of the LED is uniform and the stability is good. 6. LED colorful RGB light strips need to be equipped with controllers and amplifiers. Confirm the layout and direction of the circuit before use to ensure that the controller and amplifier are installed properly. Do not connect the red, green and blue signal lines to the black positive electrode. The sequence is reversed, otherwise the controller will be burned. The power and controller power should be selected in the order of power > RGB controller (amplifier) > light bar. Please check the line carefully after installation. Remember! Turn on the power. The scope of use of the controller must be well ventilated and dry, so as not to affect the heat dissipation. If the controller is installed outdoors, it must be equipped with a waterproof electric box. 7. If the mounting surface is metal or conductive material, a layer of insulating material must be applied prior to installation.
