Small knowledge of light strips | Application and installation knowledge of LED flexible light strips
1. LED flexible light strip application
The LED light strip is to assemble the LED light on the strip-shaped PCB flexible circuit board. Because the shape of the product is like a strip, it is named after it. LED strips have long service life, energy saving and environmental protection, and can be used indoors, outdoors or semi-outdoors. At present, LED light strips are very popular in various decoration industries. Xiaobian will briefly talk about the application and installation knowledge of LED light strips.
LED strips are widely used in hotels, shopping malls, home furnishing, automobiles, advertising, lighting, bars and other industries.
Because of its softness, LED can be curled arbitrarily, and it is easy to make graphics, text and other shapes, so it is often used as a luminous character or modeling lighting source in sign lighting. The LED light strip is hidden in the ceiling, wall or ground to outline the outline of the space, which can better shape the light environment space. On the ceiling, it is designed to be streamlined, which can stretch the space infinitely; the light strip can balance the illumination of the space and expand its sense of space; under the embellishment of the LED light strip, the original minimalist space form can be given to people. Soulful layered beauty. The LED light strip itself emits uniform light, which brings a bright light environment to the space, which not only ensures a clear visual environment, but also reduces glare. At present, LED strips are widely used in various industries.
2. Installation knowledge of LED strips
2.1 Indoor installation of flexible light strips
When the LED light strip is used for interior decoration, it is very simple to install because it does not have to withstand the wind and rain. Before installation, please clean the sundries on the installation surface to ensure that the surface is clean. The back of each LED strip is affixed with self-adhesive 3M double-sided tape. When installing, you can directly tear off the sticker on the surface of the 3M double-sided tape, and then fix the light strip to the place where it needs to be installed, and press it flat with your hands. As for some places that need to be turned or long, you can cut off the excess light strips at the scissors (the LED light strip is a circuit structure composed of 3 LEDs in series and parallel, and each 3 LEDs can be cut separately. use.)
2.2 Outdoor installation of flexible light strips
In order to ensure the service life and safety of the product, the selected products need to use outdoor protective light strips according to the environmental requirements. Before installation, the protective performance of the product should be determined. Outdoor installation will be exposed to wind and rain. If 3M glue is used for fixing, the adhesiveness of 3M will decrease and the LED strip will fall off after a long time. Therefore, outdoor installation is often fixed by card slot, which requires cutting and connection. The method is the same as the indoor installation, and it is also necessary to provide waterproof glue to consolidate the waterproof effect of the connection point.
2.3 Power connection method
The general voltage of the LED light strip is DC 12V, so it needs to use a switching power supply for power supply. The size of the power supply is determined according to the power and connection length of the LED light strip. If you don't want each LED strip to be controlled by a power supply, you can buy a switching power supply with a relatively high power as the total power supply, and then connect all the LED strip input power supplies in parallel (if the wire size is not enough, you can extend it separately), Unified by the main switching power supply. The advantage of this is that it can be controlled centrally, but the inconvenience is that the lighting effect and switch control of a single LED strip cannot be achieved. The specific method can be measured by yourself.
2.4 Controller connection method
LED marquee strips and RGB colorful strips need to use controllers to achieve changing effects, and the control distance of each controller is different. Generally speaking, the control distance of a simple controller is 10 to 15 meters. The control distance is 15 to 20 meters, and the longest distance can be controlled to 30 meters. If the LED strip has a long connection distance and the controller cannot control that long strip, then a power amplifier needs to be used to tap.
2.5 Pay attention to the connection distance of the LED strip
Generally speaking, the maximum connection distance of 3528 series LED strips is 20 meters, and the longest connection distance of 5050 series LED strips is 15 meters. If the connection distance is exceeded, the LED light strip will easily heat up, which will affect the service life of the LED light strip during use. Therefore, the installation must be carried out in accordance with the requirements of the manufacturer, and the LED light strip should not be overloaded.
3. Small knowledge of LED light strips
There is a "scissors" mark on each light strip. It can only be cut when the mark is marked. If it is cut wrongly or if it is cut off, it will not light up for one meter! It is best to carefully look at the position of the mark before, and cut it according to the unconnected place in the middle. Can.
Each light strip must be equipped with a special plug (plug with a transformer); when connecting, be sure to remove the transparent plastic cover, and then cover it after connecting the test light. Do not connect directly with a cover, it is easy to short circuit!
When the light strip is installed, it is generally placed in the light trough, and it can be straightened, or it can be fixed with a thin rope or thin iron wire. If external or vertical installation is required, additional clips and tail plugs are required. The original clip is fully transparent, it is best to put waterproof glass glue on the tail plug and plug after installation, so that the waterproof performance is better.
At present, LED light strips have been widely used, and can be seen everywhere in buildings, bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertisements, signs, signs, and LED light strips are very environmentally friendly. , favored by users and designers.
