Generally speaking, the designer’s superb design strength is one of the important factors that create an excellent night scene lighting project. In addition, the choice of light sources and lamps is the basis for shaping an excellent night scene lighting project. Let’s look at it below. How to choose the light source and lamps in the night scene lighting project?
One, how to choose the light source?
1) The life of the light source. The night scene lighting fixtures are basically installed outdoors, and the temperature changes greatly throughout the year, which affects the service life of the light source. In addition, the geographical environment of the outdoor lighting installation site is more complicated, and it is difficult to replace and maintain the lighting. Therefore, it is very important to choose a long-life light source.
2) The light efficiency of the light source. High-efficiency light sources are conducive to energy-saving lighting. Generally, high-power floodlights should be avoided when lighting design, and medium and low-power light sources should be used as far as possible under the premise of satisfying the lighting effect.
3) The color temperature and color rendering of the light source. The light color of the light source has different application methods for different areas and different objects. Generally, high color temperature light sources should be used in tropical areas to create a cool feeling; cold areas should use low color temperature light sources to create a warm feeling for people. The color rendering of the light source is generally not required in night scene lighting. Only when the shop windows and illuminated objects need to display certain parts realistically, the color rendering of the light source has higher requirements.
2. How to choose lamps?
The selection of outdoor lighting fixtures should follow the following basic principles:
1) Except for special requirements, in general, finalized products should be used as much as possible to facilitate maintenance and replacement.
2) Lamps with high efficiency, good quality, long service life, low maintenance, and energy-saving should be used.
3) Lamps and lanterns should reach the corresponding protection level according to the requirements of the place of use. Outdoor lamps for night scene lighting must not use category 0 lamps. Underwater lamps should use waterproof lamps. Outdoor installation lamps should have a protection level higher than or equal to IP55. The protection level of buried luminaires should be higher than or equal to IP67, and the protection level of underwater luminaires should be higher than or equal to IP68.
4) Underground lights should be used with caution, because they require higher protection levels, are more expensive, difficult to maintain, and prone to glare. High-power underground lamps are likely to burn people due to the high surface temperature of the lamps, so protective measures are required.
5) Lamps and lanterns should have good anti-corrosion performance, especially in coastal or heavily polluted areas.
In order to ensure personal safety, all live parts of the lamp must be isolated by insulator material to protect against electric shock. Lamps are divided into four categories according to the form of electric shock protection, namely: Class 0 lamps, Class I lamps, Class II lamps, and Class III lamps.
6) According to the characteristics of the lighting target and the requirements of lighting design, select the appropriate beam angle.
7) Commonly used lamps for night scene lighting
Fluorescent lamp (application occasions): interior lighting, decorative lighting, roads and bridges, gardens, advertisements, squares, etc.;
Floodlights: floodlighting, roads and bridges, trees, advertisements, squares, water features, mountains and rocks, etc.;
Underground lights: flood lighting, trails, trees, squares, rocks, etc.;
LED lights: internal transparent lighting, decorative lighting, colorful lights, roads and bridges, advertisements, squares, etc.;
fiber optic lights: decorative lighting, colored lights, gardens, water features, squares, etc.;
Lawn lights: paths, gardens, squares, etc.
Courtyard lights: roads, bridges, gardens, squares, courtyards, etc.;
Solar energy: lanterns, roads and bridges, gardens, courtyards, squares, etc.
