Outdoor lighting engineering design and construction should pay attention to what? How to choose the right lamp?

What should we pay attention to in LED outdoor lighting design and construction? How to design lighting engineering drawing? How to choose between different venues? As an important part of the landscape, LED outdoor landscape lighting project not only shows the means of landscape concept, but also the main part of people's outdoor activity space architecture at night. Scientific, standardized and humanized outdoor landscape lighting is of great practical significance for improving the landscape quality and external image and improving the quality of life of the owner. In most people's thinking, they will think that the object of landscape lighting design is only for buildings, familiar and unknown, and there are many objects of the usual outdoor landscape lighting design, such as overpasses, towers, squares. Today, led landscape lighting technicians introduce common outdoor landscape lighting cases in detail.

 

1, building landscape lighting project
Building night lighting project, the most commonly used flood lighting, contour lighting, internal light lighting and so on. The lighting of the building facade is to directly illuminate the building facade with the projection lamp and the wall washing lamp according to a certain Angle of the design calculation, and reshape the image of the building at night.

 

2, overpass landscape lighting project overpass is often in the city's traffic arteries, is an important part of the overall effect of urban landscape lighting. Viewed from a distant vantage point, the overpass is a series of lanes that pass up and down and then spread out. The image of the driveway is mainly expressed by the railings on the side of the driveway. Overpasses are mostly hierarchical, multi-lane vertical overlap, as well as the performance of hierarchical depth and other aspects of the relationship, in order to truly reflect the landscape charm of the overpass.

 

3, high-rise landscape lighting engineering is usually composed of several basic parts such as the base, tower body, tower top, they form a harmonious whole. The architect gave each part its own meaning when designing. They all have a corresponding role or function, and from an aesthetic point of view, their aesthetic value lies in erecting a landmark for an area. Therefore, the complete lighting performance of each part of the tower is very important, and the performance of only one part or favoriousness will alienate the overall image of the tower. The lighting Settings of each part of the tower should consider the needs of viewing.

 

Outdoor landscape lighting engineering lighting performance is to complete the integrity of the tower image, the lighting they set should take into account the feeling of people watching at close range, in the brightness of the lighting, light tone, lighting projection direction and other aspects of the configuration, should be people's visual comfort as the goal. As far as the whole tower is concerned, from bottom to bottom, the illumination of the lighting light should be gradually increased, which can create a sense of towering, and also conform to the visual law of people watching the scene.

Outdoor lighting project LED lighting how to choose buried lights

1, application scope: landscape structures, small pieces, plants, hard pavement lighting. Mainly arranged in the hard pavement lighting facade, lawn area lighting trees and other places; It should not be arranged in the shrub area to illuminate the trees and facades, so that the light forms too many shadows and dark areas; When arranged in the lawn area, the glass surface is 2-3 cm higher than the lawn surface, so that the water after the rain does not soak the glass lamp surface. 2, selection requirements light color livable lighting environment, should use the natural color temperature range 2000-6500K, according to the color of the plant to adjust the light color temperature, such as evergreen plants should use 4200K color temperature, red leaf plants should use 3000K color temperature.

 

2, the form of lamps
Under the premise of not affecting plant growth and causing no damage to plant planting soil ball and root system, the trees in the lawn area are illuminated with adjustable Angle buried lamps. The selection of buried lamps is based on the illuminated plants, and if the trees with thin branches, a set of narrow direct light of buried lamps is arranged in the roots. Lush tall trees can be arranged about 3m distance 1-2 sets of polarized buried lights lighting; Spherical shrubs are arranged wide light type or astigmatism type lamps inside; Coronal asymmetrical trees are illuminated by a set of adjustable Angle buried lamps.

 

3, lighting technology
Choose the lamp cover with chamfer treatment of the buried lamp, after installation, the edge of the lamp with waterproof glue or glass glue seal treatment.

4. Installation process
No embedded parts: standard installation, using embedded parts. The hard pavement opening is slightly larger than the lamp body diameter but smaller than the outer diameter of the steel ring. Water vapor into the phenomenon, do a good job of installation protection, the selection of lamps should pay attention to the drainage hole.

(1) During the sample delivery process, the waterproof level of the lamp must be tested to ensure that it is above IP67 (Method: put the buried lamp into the water basin, the glass surface is about 5cm from the water surface, and the power is powered for 48 hours, during which the opening and closing action is about six times every two hours, and the waterproof condition under the state of heating and cooling must be checked).

(2) The sealing of the wire connection should be done well: the wiring port of the general underground lamp has a special sealing rubber ring and stainless steel firmware. First, the cable is passed through the rubber ring, and then the stainless steel firmware is tightened until the wire can not pull out the sealing rubber ring. At the same time, when the wire is connected with the lead, a waterproof junction box must be used.

(3) Do a good job of underground water seepage treatment during construction. Trapezoidal column embedded parts with small upper mouth and large lower mouth should be used for buried lamps in lawn areas, and cylindrical embedded parts should be used for hard areas. A permeable layer of gravel and sand should be made under each buried lamp during installation.

(4) Open the surface cover after the buried lamp is installed, and cover the lamp after half an hour, so that the inner cavity of the lamp maintains a certain vacuum state, and the outdoor atmospheric pressure is used to press the lamp cover sealing ring.

Spot light

1, the scope of application "mainly used in the green belt. To achieve the purpose of beautifying the green scenery at night, to avoid the general buried lamp is easy to be covered by fallen leaves, rainy days are splashed by mud and other problems, easy maintenance; It is also commonly installed next to buildings to act as a floodlight. It should be noted that if the lights are installed in the green belt, they should be regularly distributed and hidden as far as possible, so as not to affect the landscape of the green belt during the day.

2, precautions: need to be arranged in the bush area lighting trees, lamps need to be effectively concealed in the bush area, the luminous mouth is about 10cm higher than the bush line.

3, selection requirements: Considering the daytime landscape, it is recommended to use as little as possible in the lawn area, the lamps are irregular arrangement on the green vegetation, forming a black spot in a green environment. At night, it will form too much glare, affecting the comfort of night lighting. In the case of directional lighting effects, adjustable Angle buried lights are used instead, or decorative objects matching the landscape are used to block. If there is no need for directional projection, the ordinary type of buried lamp is directly used instead, and the anti-glare grille is installed as required.

4. Installation process
Fixed process: The ground buried lamp replacement, if you must be in the form of ground plug lamp lighting, it is recommended to replace the adjustable lamp with a base, on the basis of pouring concrete base fixed, and in the bottom seat and head wiring.

Wiring process:

(1) If the power line is protected by steel pipe, the lead is protected by metal hose, and the wiring is protected by waterproof junction box. After the wiring is completed, the edge of the waterproof junction box is sealed with glue or wax, buried in the soil, and appropriate gravel is placed under it.

(2) If the power line is protected by PE or PVC, the lead is protected by a plastic hose, the wiring is protected by a plastic junction box, buried in the soil, and the appropriate gravel is placed under the ground, this approach is poor in water resistance, but the cost is lower and the installation is convenient.

(3) If the construction period is tight or it is impossible to avoid the exposure of the joint, it is necessary to use waterproof adhesive + insulation adhesive + waterproof adhesive + insulation adhesive + waterproof adhesive when wiring, five layers of alternating protection. The joint should face up and should not be placed on the ground or underground, so that the joint is free from ground water to prevent leakage and conduction. Each project can choose the appropriate process according to the cost control requirements and duration requirements.

5, the appearance of color: the general site insertion lights are black, but the actual installation effect of the insertion lights in the lawn between the shrubs seriously affected the green landscape. If the buried lamp cannot be replaced, the surface of the lamp can be treated with dark green electrostatic spray.

Wall lamp

1, application range: wall, column lighting, can be used as a supplement to functional lighting. Centralize the installation within the allowable height of the facade/column and install it as far as possible out of reach of hands (about 2.5m). If the elevation/column is low, install it as far as possible out of reach of hands of children.

2, selection requirements
Surface treatment: The surface of the lamp is treated by hot-dip galvanized electrostatic spraying process, which is used as a standard process in the procurement of lamps and lanterns, requiring manufacturers to use this process to produce and provide corresponding products. At the same time, the lamps need to be fixed with stainless steel screws, which are sprayed or painted into the same color as the surface of the lamps (this point is also applicable to courtyard lights, lawn lights, wall lights and other lamps).

Anti-glare treatment of light transmission cover: raindrop, frosted treatment, prism treatment and other light transmission cover are used in lamp sample selection. Soften the light.

Lawn lamp

1, the scope of application: small path, secondary garden road, access road, lawn and other landscape functional lighting, the height of the lamp is generally 0.4-1m, the effective lighting radius of 3-5m, the layout spacing is controlled within 10m, the layout point should be in the bush, hidden installation. When obviously arranged on the lawn, attention should be paid to the impact of its position on the landscape.

 

2, selection requirements
Light source selection: lawn light source should generally choose energy-saving lamp light source, from the maintenance of easy to consider the choice of integrated self-rectifying energy-saving lamps, should not use incandescent lamps, lamp cups and other short-life light source, the LED type of light source careful use. Color temperature is generally 3000-4200K color temperature is appropriate, high color rendering (color rendering index greater than 80).
Lamp height: For the design and selection of lawn lights, the height of the luminous mouth is about 20cm higher than the bush line.

3. Installation process
Layout position: Lawn lamps are not easy to be directly arranged in an eye-catching position without shelter under the premise of meeting the functional lighting requirements, such as lawn lights and mud lamps should not be arranged in the low lawn area, and should be adjusted to the shrub area.

Lighting fixed: the base height of the garden light is greater than 800mm, and the base is built with reinforcement. The lawn light base is larger than 400mm, which can be fixed directly with expansion screws or built-in reinforcement bars, and the surrounding planting soil is compacted.

 

Garden lamp

1. Scope of application: The courtyard light is the main functional lighting for the main roads and streets of the community, providing effective lighting guarantee for the safe walking of pedestrians at night. The height of the lamp is generally 3-5m, the effective lighting radius is 8-10m, and the layout spacing is generally about 15-20m. Considering the coordination between the lamp and the landscape, it can be installed on the arbor side on the specific point arrangement. So that it does not ruin the landscape skyline.

2, selection requirements
Light source selection: Functional lighting in the community should choose energy-saving lamps with good economy and light efficiency. Color temperature 3000-4200K, good color rendering (color rendering index greater than 80). The power of the light source is between 26-48W, and the corresponding power is selected according to the brightness requirement. The courtyard lighting source along the street should choose gold halide lamp, color temperature 3000-4200K, good color rendering (color rendering index greater than 80), power between 70-150W, according to the brightness needs to choose the corresponding power.

3. Installation requirements
The garden lights should be arranged symmetrically on the landscape axis or on the garden road with symmetrical landscape layout characteristics to strengthen the sense of ceremony. If the garden road is narrow and the symmetrical arrangement is crowded, the symmetrical arrangement of lawn lights can be used instead. At the same time, when arranging the point, pay attention to the lamps and try to avoid the glass Windows of the indoor living room and bedroom on the second and third floors, so as not to see the courtyard lights directly when the residents look outside the room at night.
