Lighting Design Analysis of Rooftop Billboards

1. Introduction

Roof-top billboards are a common carrier of outdoor advertising in daily life. They are usually set up on the roofs of buildings with dense population or large population flow and wide field of vision. This significant advantage is also the prerequisite for businesses to choose brand promotion channels. one of the conditions. The appearance design of outdoor billboards on the roof not only determines whether the advertising effect is significant, but also directly affects the overall aesthetics of the building. Therefore, good design can not only make effective use of the idle space on the roof of the building, but also promote brand promotion to obtain more effective advertising.

The billboard lights at night add a lot of brilliance to the city, especially those beautifully designed billboard lights, which are even more eye-catching. The night of the city has become more colorful since there are various lights of billboards. However, this also brings “light pollution”, which causes many residents to not rest normally at night. Therefore, it is very important to do the correct lighting design and choose the right lights. This article will take you to take a good look at the requirements for installing night billboard lighting.

2. Illumination requirements

Since we are going to install a billboard, we must hope that it will be very eye-catching and beautiful, because the more eye-catching it is, the more attractive it will be. So in order to improve the effect of advertising, we will choose to install spotlights on the billboard. In the process of using the spotlight, everyone will also pay attention to its power consumption. The following briefly introduces the power of several common billboard spotlights.

The illumination should be up to the standard, too strong or too weak light is not suitable. Excessive illumination not only consumes energy and equipment, but also produces light curtain reflection or blurred reflection, fogs the graphic layout, and even produces reflected light spots, making it out of sight and harmful to the visual health of the viewing object. Too weak light can only have a viewing effect at a close distance, and it will not work at a long distance, and it will not achieve the proper publicity effect.

First of all, we have to consider the actual effect. The power of LEDs does not need to be very large, and 30W~100W is enough. Generally, the spotlights used for roof signs and T-shaped billboards are mainly 400W advertising spotlights.

The spotlights used in outdoor billboards are generally LED floodlights/LED floodlights. The most common power is 10W, 20W, 30W, 50W, 70W, 100W. Generally, outdoor billboards use LED light-emitting color temperature: 6000k-6500K, which is positive White light. The color rendering index should be above 80Ra, and the high-quality LED flood light should use a high power factor constant current drive power supply. Brightness and other phenomena, which will cause unnecessary costs for replacement and maintenance.

3. Selection of lights

Neon sign billboards have been around for nearly a hundred years. Due to the continuous progress of neon sign technology, new neon signs are constantly appearing. It is expected that they will not be replaced by other lighting for a long period of time in the future. new development.

The outdoor advertising signs made by the light guide tube have particularly clear picture patterns, bright colors, and easy maintenance. There is no need to open the light box. The maintenance personnel can open the light source box of the light guide tube on the ground to repair and replace the light source.

It is recommended to use waterproof light sources for the light source of large-scale roof luminous characters. Although waterproof light sources are more expensive than ordinary light sources, their lifespan is relatively long. Since more than 80% of LED luminous characters are installed outdoors, they are Attention should be paid to the LED waterproof light source. At the same time, viscose should be used around the sideband to prevent water infiltration from causing adverse effects on the LED light source.

It is necessary to choose a light source with a high color rendering index, and a light source with a high luminous frequency and energy saving. Internal light-transmitting and self-illuminating storefront signage directly illuminates the surface through an internal light source. To express the content of the logo, low-energy light sources such as light-emitting diodes of corresponding colors can be selected.

The billboard lights in main roads, window areas, and tourist attractions can be configured in the form of rigid tube neon lights, background lights, etc., and the lighting should be reasonably configured in combination with the regional environment and store style, so as to achieve novel design, combination of dynamic and static, and show night landscape effects.

4. Installation precautions

First of all, we need to understand some requirements for night billboards in daily life. The first is that before 23:00 every day, the vertical illuminance of residential windows is limited to less than 10Lux, so as to avoid the lighting of outdoor billboards at night, which will affect the normal life of residents.

After 23:00, the vertical illuminance of residential windows is limited to 5Lux. In addition, the night lighting of outdoor advertising facilities requires automatic control of the lighting period. From 0:00 to 5:00 every day, outdoor advertising facilities are prohibited from turning on the lighting devices.

Before installing LED floodlights, in order to ensure the quality of use after installation, it is recommended to conduct a detailed inspection of the floodlights on site before installation to see if the appearance of the LED floodlights is damaged. After confirming that the appearance is not damaged and the accessories are complete, it is necessary to prepare the installation after the LED floodlight arrives at the construction site. First, organize the installers according to the installation drawings attached by the factory, and connect a few floodlights to test whether the installation drawings are correct or not. . Finally, after the LED flood light is fixed and connected, it is best to use a multimeter on the main power supply to check whether there is a short circuit in the wrong wiring when you are ready to test it.

5. Conclusion

To summarize the key points that need to be paid attention to in the lighting design of the top floor billboards are as follows:

It should meet the requirements for billboard lighting in the special planning for urban night scene lighting.

The corresponding lighting method should be selected according to the type, structure, form, surface material, color, installation location and characteristics of the surrounding environment of the billboard.

The use of light and color should be in line with the cultural connotation of the advertising content and the surrounding environment, and should pay attention to the coordination of the day and night landscape, and achieve harmony during the day and night.

While ensuring the lighting effect, light pollution caused by night scene lighting should be prevented. The operation and management of night scene lighting facilities should be done well to prevent light pollution during the operation of the facilities. It is advisable to use low-energy-consumption and energy-saving products as lighting methods. Encourage the use of energy-saving green light sources and non-standard lighting products.

Billboard lighting should not produce light pollution, should not interfere with the normal use of public facilities such as communications and transportation, and should not affect the normal running of motor vehicles. Except for commercial places that are open all night, billboards should be controlled with reference to the regulations on the lights-out period of outdoor advertising.

When installing lights, it is best to illuminate from the bottom right to the top, and the light cannot be reflected. As long as you can light up the billboard, there is no need to light it. No downward lighting or astigmatism; there are certain requirements for the use of lights. It is best to use yellow lights, incandescent lights and lights with strong brightness. Some more dazzling lights are not allowed.

The use of outdoor LED billboard lighting should not harm the interests of others, and should not ignore other factors for self-interest. Therefore, there must be a reasonable plan before installation. The analysis on the lighting design and installation of billboards on the top floor is here, I hope it can help readers in need!
