LED billboard waterproof
Currently, LED billboards with luminous characters are relatively popular. Here are some common luminous characters.
1. Acrylic luminous characters
Three-sided acrylic full-body 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 sources. 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 luminous characters
The material function of blister luminous characters is similar to that of flat luminous characters, except that the strokes of the characters are raised tangible surfaces. The advantages are more classy, strong, wear-resistant and waterproof. , energy saving. It is suitable for all kinds of outdoor advertising characters, and the whole blister panel is more suitable for store signboards and image walls.
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 signboards, KTV, nightclubs, hotels, guesthouses and other entertainment venue signboards.
The exposed luminous characters are iron characters, stainless steel characters, aluminum characters, and titanium characters. The surface of the characters is punched and equipped with a single LED waterproof light string. Commonly used materials for making exposed luminous characters include: acrylic plate, galvanized plate, stainless steel, and titanium plate. Features of LED exposed luminous characters: Comparing the advantages and characteristics of large-scale exposed luminous characters and internal luminous characters, exposed luminous characters have a higher cost performance than blister characters. After analysis, it has the following characteristics: Because the lamp is exposed, the exposed luminous characters are not affected by other things, so the brightness is higher than that of the blister luminous characters. The cost is relatively low. Conventional blister characters are also called light box characters, which are composed of two sets of characters and lights inside. Therefore, the cost is relatively high. As for LED external luminous characters, a set of characters can be made from iron sheet or stainless steel, and then the lights can be installed by drilling holes, which saves costs. The light is uniform. Since the blister characters are limited by the size of the strokes, there is no way to assemble the strokes that cannot be assembled by ordinary modules. Therefore, there will be uneven brightness of a character. The externally luminous characters are installed with a single LED light. Therefore, this phenomenon does not exist with the LED externally luminous characters (unless the lamp is broken).
Easy to maintain, the lamp beads with exposed characters can be removed from the outside, while the characters on the side of the blister light box need to be removed. For high-rise buildings, it requires a lot of cost to dismantle the words, repair them and put them back together. For example, you need to build a shelf or rent a hanging basket to do it. Generally, exposed characters are 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. The characters can be baked into various colors of paint. You can light up whatever color lights you need at night. They are not 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. . If the characters are too large, they need to be spliced, which will greatly affect the appearance and cause certain joints.
