Is led billboard waterproof?

The installation of outdoor billboard LED electronic displays has four links: on-site investigation, equipment construction, installation, and debugging.
1. On-site survey
This refers to the fact that before installation of some outdoor LED displays, they should be tested uniformly according to the specific environment, topography, luminous radiation range, brightness acceptance and other parameters. In order to ensure that the advertising The smooth installation of the sign requires that before lifting and installation, a unified lifting plan must be implemented for the commander to ensure that the equipment can be used normally and stably.
2. LED equipment construction
When building some outdoor LED billboards, wall advertising screens, hanging advertising screens and rooftop advertising screens should be treated differently. During actual installation, cranes and winches should be used for segmented lifting according to the distance and height, while ensuring that the personnel above cooperate with each other. There is a better installation and use process for LED advertising screens that work at high altitudes.
3. Debugging of luminous radiation range
Next, the specific radiation range needs to be detected. Due to different radiation ranges, the LED display screen construction angles will also be different. It must be based on the on-site acceptance ability and We usually perform fixed installation work on outdoor LED displays within the normal viewing angle range to ensure that normal, balanced images and subtitle information can be seen from every angle.
4. Follow-up inspection and maintenance
Follow-up inspection includes many areas, such as LED display waterproofing, heat dissipation layer, LED display waterproof coating, rain-proof area above the display screen, and heat dissipation spaces on both sides. , power supply lines, etc. These basic parts and components constitute the entire graphic LED display with good stability. Later technical maintenance requires unified management and maintenance of these parts. If the product is rusty or unstable, , when damaged, it needs to be replaced in time to ensure the safe use of the entire display screen.

Currently, LED billboards with luminous characters are relatively popular. Here are some common luminous characters.

1. Acrylic luminous characters

Three-sided acrylic luminous characters, the front and sides are acrylic, the bottom plate is PVC surrounding the characters: the material is acrylic (imported board and domestic board) panel , thick PVC material surrounds, and the inner core of the characters is covered with LED light source. The advantages are that it lights up at night, the surface is glossy, the color is bright, waterproof, and the most important thing is energy saving. The disadvantage is that the characters cannot be made too small. It is suitable for indoor and outdoor, store signboards, Large corporate promotional building word logo.

2. Blister-shaped luminous characters

The material function is similar to that of flat luminous characters, except that the character strokes are raised tangible surfaces, which have the advantages of being more classy, ​​strong and wear-resistant. Damage-resistant, waterproof and energy-saving. It is suitable for all kinds of outdoor advertising characters, and the whole blister panel is more suitable for the signboards and image walls of Zhanxiang liquid stores.

3. Light box characters

It combines the craftsmanship of stainless steel and aluminum characters. The biggest breakthrough is that the characters emit light by themselves, eliminating the need for external lighting at night. , the specific method is to hollow out the text strokes, replace them with light-transmitting acrylic sheets, and install cold light source 3.3 (daylight tube) or neon lights in the inner cavity of the text, so that it can take advantage of the natural contrast effect of colors during the day, and at night For example, it emits light by itself, and there are no spots caused by external lighting on the surrounding walls. The text effect is quite obvious, but the disadvantage is that the cost is higher and the maintenance is slightly complicated. You need to use tools such as a gondola to remove the outer panel to replace the light source.

4. LED luminous characters

LED is a sign material category that has just developed rapidly in recent years. It can replace neon lights and can be used in restaurants, shopping malls, convenience stores, open-air squares and buildings. Light box signs and luminous characters. It has the advantages of high brightness, long life (up to 150,000 maintenance-free hours), high efficiency, easy installation, reliable performance, and high cost performance, making it widely used.

5. Exposed luminous characters

The plane and surrounding edges are the same as those of ordinary luminous characters. The only difference is the light source, which is composed of small dot LED lamp beads and covers the panel with characters. The advantage is that it can emit a strong light source no matter day or night, and it is energy-saving. Other features are the same as the Yak edge luminous characters, and it is suitable for use in store signs, KTV, nightclubs, hotels, guesthouses and other entertainment venue signs.

Hello, let me answer your question. The waterproof level of LED floodlights is generally IP65, which means they cannot be immersed in water. Of course, some special floodlights use glue-filled waterproofing technology, and the waterproof level can reach IP66 or IP67, but these are only for a few RGB color high-power LED floodlights. In theory, these floodlights can be used with a certain water pre ssure or a certain Time class soaked in water. The best-made floodlights have a waterproof rating of IP68, which means they can be immersed in water for a long time. Of course, this kind of light is no longer called a floodlight. It is called an LED underwater light, which is suitable for use in water. LED underwater lights and LED floodlights have similar appearances in some varieties, but the price of the former is extremely high due to manufacturing difficulty and material issues.
The floodlights used in outdoor billboards are generally integrated high-power floodlights. Common powers are 10W, 20W, 30W, 50W, 70W, and 100W. Generally, outdoor billboards use a light color of 6000k-6500K, which is white light. High-quality floodlights also use high-power factor power supplies, but this technology is not very mature in China and the cost is very high. The power of floodlights used for outdoor billboards depends on the size of the billboard you use. Generally, the irradiation area of ​​10W floodlights is 2㎡, and the optimal illumination position is 1m. It is suitable for billboards with a height of 1M; 20W floodlights The irradiation area is 4㎡, the optimal irradiation position is 2m, and it is suitable for billboards with a height of 2M; generally, the irradiation area of ​​30W floodlights is 6㎡, and the optimal irradiation position is 3m, suitable for billboards with a height of 3M; 50W floodlight irradiation The area is 8㎡, the best illumination position is 5m, and it is suitable for billboards with a height of 5M; the 70W floodlight illumination area is 10㎡, the best illumination position is 7m, and it is suitable for billboards with a height of 7M; the illumination area of ​​100W floodlights is 10㎡, the best irradiation position is 10m, suitable for billboards with a height of 10M. Of course, in many cases, in order to make the light emitted by the floodlights more uniform, the illumination distance is adjusted and up-and-down lighting is adopted to solve the installation difficulty and light distribution problems.

It’s good to leave out the words.
1. Waterproof, energy-saving and safe: As we all know, LED luminous characters have low power and low power consumption. It is safer due to its low output voltage. Since the LED external light source we apply is waterproof, it can be used normally in weather such as rain without worrying about burning out. 2. Not limited by size: Generally speaking, internally illuminated characters such as LED blister are limited by blister machines. Many large characters need to be spliced, which damages the beauty of the characters. Large LED exposed characters are generally bent by plasma cutting. It is made, so it is not limited by the size of the machine. No splicing, more beautiful. 3. Not limited by the color of the characters: Generally, internal luminous characters are limited by the organic board. For example, red blister characters usually have a red light source inside and emit red light. However, this is not the case for exposed luminous characters. You can Bake the characters into various colors of paint, and light up whatever color lights you need at night, without being affected by the background characters at all. Moreover, because the large characters are high off the ground, the exposed LED lights are not obvious during the day. 4. Easy maintenance: Although LED lights rarely break, if they encounter poor wire contact or break under special circumstances, they need to be repaired. This kind of LED exposed characters only need to be hoisted to the broken position of the billboard. Just pull out the broken lamp from the front and replace it. Internally illuminated characters require the characters to be disassembled and replaced with new modules before the characters can be installed. Large characters cannot be repaired simply by lifting them from above.
