Billboard Lights

Billboards are ubiquitous in our lives, large and small stands in front of our eyes, and the night lighting of billboards has also become a major focus of billboards. At present, the lighting of billboards has always been metal halide. Floodlights are the mainstay, and the two power applications of 250w / 400 are more common. However, with the rapid decline of global resources, energy saving has become an urgent matter. In recent years, with the continuous demand for night lighting of outdoor buildings, Increase, more and more LED flood lights have been applied to the lighting project of outdoor billboards, and this kind of LED flood lights use LEDs with energy-saving effects as the light source, and achieve nighttime under the control of built-in microchips Lighting effect. As a new-generation light source, LED has gradually entered people’s sight.

Billboard types:

1.Neon billboard:

It is made of neon tubes bent into text or patterns, and matched with neon tubes of different colors, emitting colorful colors. It can also cooperate with the electronically controlled flashing form to increase dynamics, and the visual impact at night is strong.

2.Single-pillar billboard (referred to as single-pillar)

The billboards are placed on special support pillars, most of which are T-shaped or P-shaped pillars. The advertising devices are set up on highways, main traffic arteries and other places, facing dense traffic and people. The commonly used size is 6 meters high by 18 meters wide, mainly using spotlights as lighting equipment.

3.Large light box

It is placed on the building’s exterior wall, roof, or podium. It is a color billboard during the day, and it lights up at night to become a light box advertisement for “inside lights.” Light box advertising has better lighting effects, but it is more difficult to maintain than spotlight billboards, and the tubes used are more prone to wear.

4.Bus shelter billboard

Outdoor media installed in bus shelters. Light boxes are the main form of expression. The advertisements arranged on such media are mainly consumer goods. You can purchase multiple stand kiosks individually or online to achieve wider coverage and even cover multiple cities.

5.Subway advertising

Various advertisements set in the subway are collectively referred to as subway advertisements. Its forms include twelve light boxes, four aisle posters, special position light boxes, escalators, and posters in the carriage. It is characterized by a concentrated flow of people and a high degree of attention, which can increase the awareness of the product. Can be purchased separately or online.

6.Bus Advertising

The bus belongs to mobile media, with the form of full-body painting and banner hanging panels on both sides of the body. It is characterized by wide contact area and high coverage, and can choose routes or regions according to the target audience. Can be distributed individually or online. Airport advertising. Billboards placed around and inside the airport. It is generally targeted at higher-level and higher-income audiences, such as business traveller and tourists.

7.Railway Station Advertising

The advertising form set within the range of the railway station has been the main target audience since then. It is characterized by high foot traffic and can cover neighboring areas. Its advertising forms include light boxes, electronic screens, spotlight billboards, three-sided flips and so on.

In the outdoor advertising industry, LED energy-saving lamps with floodlights are installed on those large billboards. Floodlights are widely used in the market. There are many types of billboard energy-saving floodlights. Billboard energy-saving floodlights are divided into: LED floodlights; outdoor waterproof LED floodlights, white LED floodlights, indoor lighting fixtures, outdoor billboard lighting LED floodlights , High-power LED lighting, energy-saving LED lighting, indoor energy-saving lighting LED flood lights. These flood light products use imported chips, high brightness, low energy consumption, low heat, long life up to 100,000H, can be divided into monochrome, discoloration. The two materials are made of high-pressure cast aluminum molding shell, 4mm tempered Safety glass. There are two kinds of light distribution options: symmetrical and asymmetrical. Lighting appliances-compact, light and beautiful, easy to install. Can be dustproof and waterproof, easy to maintain. Places of use: architectural floodlight LED floodlight, tennis court LED floodlight, parking lot LED floodlight, stadium and dock LED floodlight, landscape lighting, fountain lighting, stage LED floodlight projection, building Lighting E flood light, billboard lighting LD flood light, green landscape lighting I ED flood light. Hotel LED spotlights, special lighting for cultural lights: bar LED spotlights, ballroom LED spotlights and other entertainment venues.

Billboard lamp lighting design requirements

The billboard lamp lighting should meet the city’s most overall planning requirements. Because the billboard itself has a composition and color that match the characteristics of the product it recommends, all light sources should be selected based on its light color characteristics. Do not use bright colors and colorful Lighting, otherwise the advertisement itself will lose its artistic appeal. The light color of outdoor advertising lighting refers to the color temperature and color rendering of the light source. The location, form, shape, color, and specifications of the installation must be in harmony with the surrounding environment, and it must not blindly pursue the effect of night lighting and affect the normal life of transportation, municipal utilities and people. Good advertising lighting should not only illuminate, but also be beautiful, artistically attractive, and avoid light pollution and energy waste. Billboard lights, according to the optimal brightness level and brightness distribution, select appropriate light sources and reasonable lamps and lanterns to display the artistic conception and charm of advertisements. Inappropriate lighting of advertisements will cause excellent advertisements to lose their due demeanor, and the glare will directly affect the effects of traffic lights, traffic light signs, and even cause traffic accidents.

Billboard lights metal halide and LED lights

The difference between metal halide flood lights and LED lights

1.Difference in light source type: Metal halide lamps are hot light sources; LED lamps are cold light sources. LED energy is conserved. Except for conversion into visible light, excess energy will be dissipated in other ways.

2.Differences in the dissipated form of excess energy: Metal halide lamps dissipate excess energy by means of infrared and ultraviolet rays, but infrared and ultraviolet rays will affect product quality and affect human physiology; LED lamps generate heat through light source devices and consume excess energy , Heat conduction is very easy to control.

3.The difference in the temperature of the lamp shell: the temperature of the metal halide lamp’s shell is very high, which can exceed 130 degrees; the temperature of the lamp shell of the LED lamp is extremely low, which is normally below 75 degrees. Safety and life of electric wires, supporting electrical appliances, etc.

4.Difference in vibration resistance: The filament and bulb of metal halide lamps are easily damaged, and the vibration resistance is poor; the light source of LED lamps is electronic components, which are inherently resistant to vibration. LED lamps have incomparable advantages in terms of vibration resistance.

5.the difference in light distribution performance: metal halide lamps have difficult light distribution performance, large waste, uneven light spots, large reflectors are required, and the size of the lamp is large; LED light lines are extremely easy to control, and can achieve a variety of light distribution in the same volume , The light spot is even. The convenient feature of LED light distribution can greatly save the waste of light in the light distribution and improve the system light efficiency of the light.

6.the difference between anti-grid voltage interference: metal halide lamps: poor, lamp power changes with the grid voltage fluctuations, it is easy to overload; LED lights: stable, constant current power supply can keep the light source power unchanged when the grid voltage fluctuates. LED lamps can work normally during the fluctuation of the grid voltage from 90-265 volts, and have no impact on the life of the light source and the lamp.

Metal Halide Lamps

Metal Halide Lamp is operated by AC power supply. It produces arc discharge in a mixed vapor of mercury and rare metal halide. It is a discharge lamp that emits light. Metal halide lamps are based on high-pressure mercury lamps with various metal halide. Made of the third generation light source.

Disadvantages of metal halide lamps

Self-power consumption: Due to the use of inductive ballasts, metal halide lamps have high power consumption, high operating current, and generate very high starting current at the instant of startup. For example, 400W metal halide currents can reach as high as about 15A at the instant of startup, which greatly affects the life of the appliance Large, often damaged facilities for air switches. At the same time, the ballast itself consumes a large amount of power, which causes huge electricity expenses for the user and speeds up the aging time of the line. Because the LED uses a constant current driver, the power consumption is low and the power factor is high to avoid the above problems.

■ Color rendering index

It is an important parameter to measure the visual quality of the light source. The color rendering index is high, and things look clear under the lights, and the colors are real; on the other hand, things look unclear under the lights, the light is blurred, and the objects are distorted. The metal halide lamp 65 has a low color rendering index. Working under these light sources can easily cause myopia and visual fatigue.

■ UV content

Ultraviolet light is a terrible light, which can cause serious damage to eyes and skin, causing eye diseases and skin cancer. The ultraviolet content of traditional light sources is very high. For example, the halogen content of metal halide lamps accounts for 34% of the total luminous flux. Working under metal halide lamps for a long period of time will cause considerable harm to the human body. LED do not contain ultraviolet rays.

■ Restart ability

After the metal halide lamp is turned off, it needs to wait for a period of 10 minutes before it can be restarted, otherwise it will burn out and cause a lot of inconvenience to use; it is a kind of light pollution, which is caused by the light source itself or the improper matching of the light source and the lamp. Working under glare can cause visual fatigue and visual errors, and is also the main cause of myopia. Metal halide lamps due to light refraction caused by uneven manufacturing of glass bulbs, so their own glare is very serious, and they are all point light sources, and it is easy to form a focal point to cause glare when matched with lamps.

■ Strobe

It is a kind of light pollution, which is caused by the periodic change of the light flux of the point light source with the AC voltage. Strobe is the “invisible killer” of the lighting environment, which can cause myopia and migraine headaches. The strobe of metal halide lamps is very serious. Human eyes will feel the flash of light, which will cause great damage to the human visual system. The LED does not flicker because it rectifies AC into DC, and the DC voltage does not change periodically.

LED flood light

LED flood light is a kind of point light source that can illuminate evenly in all directions. Its irradiation range can be adjusted arbitrarily, and it appears as a regular octahedron in the scene. Flood light is the most widely used light source in the production of renderings. Standard flood lights are used to illuminate the entire scene. Multiple flood lights can be applied to the scene to produce better results. Flood light is the most widely used light source in the effect map. Multiple flood lights can be used to coordinate the scene to produce better results. It is to illuminate objects uniformly from a specific point in all directions. It is best to use it as an analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the range of the camera or inside an object. How many different distances to use in a scene? Colored flood lights are very common. These flood lights can cast shadows and mix on the model. Because the range of the floodlight is relatively large, the effect of the floodlight is very easy to predict, and there are many auxiliary uses of this light. For example, if the floodlight is placed near the surface of the object, Produces a bright light.

Advantages of LED flood light

High luminous efficiency: Metal halide lamps 90 ~ 140 lumen/ watt, most of the power consumption becomes heat loss. The LED light source can reach 50 ~ 200 lumens / watt, and its light is good in monochromaticity and narrow in spectrum. It can directly emit colored visible light without filtering. Energy saving, low power consumption and long service life. Safe and reliable: low heat, no heat radiation, cold light source, can be safely touched, no glare; does not contain mercury, sodium and other substances that may endanger health Environmental protection: LED is an all-solid light-emitting body, which is shock-resistant, impact-resistant and not easily broken. The waste can be recycled without pollution. The light source is small in size and can be combined at will, which is easy to develop into a light, thin, short and small lighting product, and it is also easy to install and maintain.

 LED billboard lights Features :

(1) Environmental protection and no pollution.

Traditional fluorescent lamps contain a large amount of mercury vapor, and if broken, the mercury vapor will volatilize into the atmosphere. LED fluorescent lamps do not use mercury and do not contain lead and mercury, which protect the environment. LED fluorescent lamps are recognized as green lighting for the 21st century.

(2) Efficient conversion and reduced fever.

Traditional lamps produce a lot of thermal energy, while LED lamps convert all electrical energy into light energy, which will not cause energy waste. And the documents and clothing will not fade.

(3) Quiet and comfortable, no noise.

LED lamps do not generate noise. It is the best choice for places using precision electronic equipment. It is suitable for places such as libraries and offices.

(4) The light is soft and protects the eyes.

Traditional fluorescent lamps use alternating current, so they produce 100-120 strobes per second. LED lamps convert AC power to DC power directly without flicker.

(5) No UV rays and no mosquitoes.

LED lamps do not generate ultraviolet light, so there are not many mosquitoes around the light source like traditional lamps. The room will become cleaner and more tidy.

(6) The voltage is adjustable.

Traditional fluorescent lamps are lit by the high voltage released by the ballast and cannot be lit when the voltage decreases. The LED lamps can be lighted within a certain range of voltage, and the brightness can be adjusted.

(7) Save energy and have longer life.

The power consumption of LED fluorescent lamp is less than one-third of that of traditional fluorescent lamp, and its life is 10 times that of traditional fluorescent lamp. It can be used for a long time without replacement, reducing labor and related costs, and more suitable for places that are difficult to replace.

(8) Strong and reliable, long-term use.

The LED lamp body itself uses epoxy instead of traditional glass, which is more sturdy and reliable. Even if it is hit on the floor, the LED will not be easily damaged and can be used safely. It is also easier to transport.

In summary, compared to LED lights, metal halide lights have large power consumption, low power efficiency, low color rendering index, dim light, poor color reduction ability, poor brightness controll ability, short life, and high maintenance costs The disadvantages of poor light distribution, high power, and extremely high wiring costs are that LED floodlights are energy-saving, environmentally friendly, long-lived, and highly controllable. Traditional metal halide floodlights will be replaced by LED floodlights. In addition, the state has paid more and more attention to energy saving and environmental protection issues. As the fourth generation of green light sources, LED floodlights have been supported by the state for development, and will soon replace the traditional lamps on the market today. Compared with traditional metal halide lamps, the use of LED lighting has great savings in terms of economic cost and environmental protection. Is the best choice for billboard lights.
