Outdoor Light

Outdoor lights include road lights, landscape lights (Chinese lights, fireworks lights, cherry blossom lights, etc.), lawn lights (stainless steel turf lights), underground lights, wall lights, outdoor spotlights, flood lights, wall washer lights, etc. Road lights, landscape lights, fireworks lights, cherry blossom lights, underground lights, lawn lights, wall lights, spotlights, spotlights, wall washer lights, etc.

What are the common outdoor lights?

Street light

Road lights (English: road lamp / street light): Roads are the arteries of the city. The main lighting is a street light, which is a lighting facility provided on the road to provide the necessary visibility to vehicles and pedestrians at night. Road lights can improve traffic conditions, reduce driver fatigue, and help improve road capacity and ensure traffic safety. Garden lights, landscape lights, and street lights form a three-dimensional lighting mode, which enhances the decorative effect of the road and beautifies the night scene of the city. It can also make up for the lack of illumination of the road lights.

Airport lights

The airport navigation lights are the general name of the lights located in the prescribed area of the airport to provide visual guidance for aircraft taking off, landing, and taxiing at night or in low visibility conditions.Airport lights are visual aids for landing at night and in complex weather, and important auxiliary equipment for radio approach and landing systems. It has evolved from simply providing visual instructions and guidance signals for aircraft approaching and landing at night, and has been developed to be used in conjunction with a radio approach and landing system to ensure that aircraft are approaching and landing under conditions of low visibility at day and night. The characteristics of the airport lighting system are composed of 4 main factors, which can be called 4 “C”, namely the configuration, color, light intensity and effective range.

LED Tunnel Light

Led tunnel light is a kind of light-efficient energy-saving lamps and lanterns. The light-emitting diode (LED) is used as the light source of the light-emitting body. The light efficiency is high, the life is long, and different reflectors can be used to achieve multi-purpose lighting. Dazzling or other discomfort. The ballast uses overheating protection technology to ensure the service life of the lamp. Imported high-purity mirror aluminum anodized materials are used as reflectors and through precise light distribution design, power factor is greater than 0.9, high reflective efficiency, good light transmission, energy saving and environmental protection.

(1) Low light decay: If the heat dissipation conditions are good, the first 10000h of the LED is positive light decay, the first 10000h light decay is 3% to 10%, and the first 50,000h is basically 30%, which is far lower than ordinary road lighting sources Luminescence is more stable.

(2) High color rendering: Generally, the color rendering of LED is about 70 ～ 80, which is higher if using three-color phosphors; general high-pressure sodium lamps are 20 ～ 35, and low-pressure sodium lamps are lower, so even the brightness of traditional light sources Higher than LED, but the visual effect is worse than LED, “not the brightest, but the clearest look” This should be a direction of LED light source application development.

(3) Lifetime: The lifespan of LEDs is higher than that of general road tunnel lighting sources, and now generally higher than 80,000H.

Stadium lights

Stadium lights-flood lights. Floodlights are lamps designed to illuminate the illuminated surface higher than the surrounding environment. Also called spotlight. Generally, it can aim in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the exiting beam of the flood light is wide and narrow, and the range of variation is between 0 ° and 180 °. Among them, the beam is particularly narrow and is called a searchlight. ‍

Underground lights

Underground lights are square and round in shape, and are widely used in shopping malls, parking lots, green belts, parks, tourist attractions, residential quarters, urban sculptures, pedestrian streets, building steps, and other places, mainly buried in the ground It is used for decoration or indication lighting, and also for wall washing or tree lighting. Its application has considerable flexibility.

Moving lighthouse 

Mobile lighthouse is suitable for large-scale, high-brightness lighting on the scene of various large-scale construction operations and mining operations. It is suitable for large area lighting such as emergency repair, accident treatment, flood prevention and flood relief, emergency rescue and disaster relief. 4 200w high-efficiency energy-saving lamp heads are used, with high brightness, large coverage, and both far and near lighting. The light source life is more than 10,000 hours, which is especially suitable for outdoor large-scale work lighting.

The lighthouse lifting rod is made of high-strength alloy material, which can realize automatic lifting adjustment, the maximum lifting height is 10 meters; the four lamp heads can be individually adjusted up, down, left, and right to cover the work site. The lighthouse is made of a variety of high-quality alloy materials as a whole, with a compact structure and stable performance. It can work normally in a variety of harsh environments and climatic conditions, and has a wind resistance level of 8.

Optimized structural design, easy to move and move, connected to the trailer can be easily moved to any construction and emergency site.

Wall lamp

The wall lamp has a beautiful appearance, with simple and beautiful lines. There are many styles and various forms, and they are generally placed in the community, park, or stigma, which is highly appreciated. It is simple to install, easy to maintain and consumes less power. The light source is generally an energy-saving lamp. Materials are generally stainless steel, aluminum products, iron products. The surface of the lamp body is electrostatically sprayed. The lamp body is generally welded with flat iron. After the lamp body is electrostatically sprayed, the surface is bright and clean, the color is bright, the brightness is uniform, and it has strong anticorrosive performance requirements. It is usually fixed with four screws during installation, and has enough strength to fix it.

Spotlights are used like flashlights and are generally used outdoors. There are also indoor use, because the variety is different, so the use is also different.

Spotlights

Spotlights are lamps that make the specified illumination on the illuminated surface higher than the surrounding environment, also known as spotlights. It can usually aim in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the exiting beam of the flood light is wide and narrow, and the range of variation is between 0 ° and 180 °. Among them, the light beam is particularly narrow and is called a searchlight.

Wall washer

The wall washer, as the name implies, allows the light to wash the wall like water. It is mainly used for architectural decoration lighting, and also used to outline the outline of large buildings. Because LED light sources have energy saving, high light efficiency, rich colors, and long life. Features such as length, so other wall-washing lights are gradually replaced by LED wall-washing lights. The technical parameters of LED wall-washing lights are generally similar to LED flood lights.

What should we pay attention to when using outdoorlights?

The outdoor lights used in many communities in China are 220V high-voltage lights. Once a leakage or damage occurs, it is easy to hurt people. In contrast, foreign countries have considered this in detail. Most of the outdoor lights The voltage of the transformer is reduced to keep it within the safe voltage of the human body to ensure safety. In addition, some garden outdoor lights use glass products appropriately. Some people think that glass is also one of the unstable factors in the safety of outdoor lights. However, experts believe that good quality glass (especially special glass) can hurt people even if it is broken. Small, if the developer can pay attention to the use of building materials, and at the cost of using good materials, can greatly improve the safety factor.

Installation of outdoor lights

Outdoor lighting designers must consider the working environment of outdoor LED lamps. Due to the more complex working environment, LED outdoor lighting lamps are affected by natural conditions such as temperature, ultraviolet rays, humidity, rain, rain, sand, and chemical gases. Will cause serious problems of LED light decay. So in the end, outdoor lighting designers should consider the impact of these external environmental factors on LED outdoor lighting when designing.

1.outdoor LED lamps should pay attention to the selection of heat dissipation materials. The housing and the radiator are designed as one to solve the heating problem of the LED solar power generation system. This method is better. Generally, aluminum or aluminum alloy, copper or copper alloy are used , And other alloys with good thermal conductivity. Heat dissipation includes air convection, strong wind cooling, and heat pipe cooling. (Air-cooled cooling is also similar to heat pipe cooling, but the structure is more complicated.) What kind of heat dissipation method has a direct impact on the cost of the lamp should be comprehensive Consider and choose the best solution in conjunction with the design product.

2.Outdoor LED chip packaging technology At present, most domestically produced LED lamps (mainly street lamps) are assembled using 1W LEDs in series and in parallel. This method has higher thermal resistance than products with advanced packaging technology, and it is not easy to create high Quality lamps. Or use 30W, 50W or even larger modules to assemble to achieve the required power. The packaging materials of these LEDs are encapsulated with epoxy resin and silicone.

Specification for outdoorlight arrangement

According to the wattage and related height setting of the lighting fixture, there are no hard and fast rules. For example, in general, landscape courtyard lights for road lighting in residential areas generally use 45 watts, the height is generally about 3-3.5 meters, and the spacing is 15 meters (because its radiation radius is 12-15 meters). The decorative low-wattage landscape lights live at random intervals and are determined according to the design intent. Lawn lights are decorative lamps, and there is no requirement for lighting distance. Generally, the distance is determined according to the needs of the design node. Large wattage high pole lights are used in squares, generally requiring 400 watts, a height of more than 15 meters, and a radiation radius of 30-40 meters … but these are just general laws and not standard. There are many design factors when arranging lamps, which are different from municipal lighting. For example, we should try to avoid dark areas with blind spots in corners and paths, try to avoid occupants’ windows being too close to lighting fixtures, and install floor lamps, etc. to avoid causing light pollution, etc … Many empirical issues should be based on the scene Actual setting.

1. In terms of safety, electrical lighting in public places should be protected against electric shock caused by short circuits;
2. Rain-prevention, which is often hit by heavy rain in our southern region;
3. Anti-ultraviolet light. Some outdoor lamps and lanterns use inferior clinker as the shell. Prolonged exposure to sunlight can easily distort or damage the plastic.
4. The aesthetics of the lamps should be coordinated with the surrounding environment or building
5. The distance of the lamp from the wall. The lighting is reasonable, the illumination is uniform, the distance between the lamps should not be too large, and it should not be too far from the wall. Generally, the distance from the lamp to the wall is 1 / 3–1 / 2 of the distance between the lamps.
6. The distance-to-height ratio of the lamp is L / h. Whether the arrangement of the lamps is reasonable depends mainly on whether the ratio between the distance L to the lamps and the calculated height h is appropriate. The L / h value is small, the illumination uniformity is good, but the investment is large, and the economy is poor; if the L / h value is too large, the lamp is scarce, and the illumination uniformity is poor.

The importance of using outdoor lights for us

In outdoor activities, it is very inconvenient to have no light at night, and the lamps are a must-have item for camping in the wild. If you do any activity at night (such as writing a diary), the flashlight also has a high-capacity alkaline battery, which may be necessary. The flashlight does not have to be large, it is better to use a small and waterproof one. Some special products also have a foldable bracket, which is also very practical. The flashlight is not very convenient when two hands are occupied at night or in the dark. It is better to change the lighting tool to a more convenient headlight. The headlight does not need to be operated with both hands, as long as it is worn on the head. The headlights for outdoor activities are similar to those used by miners, except that outdoor headlights are lighter. In fact, in actual outdoor activities, most people bring their headlights and flashlights. It is best to use camp lights when camping. The camp lights are bright enough to use several tents throughout the camp. If sheltering from the wind, candles may be a better choice.
