1. Landscape and LED light source
Science requires analysis and understanding, landscape lighting requires appreciation and taste, and art requires deep intuitive perception. Landscape lighting art must be through light and lighting to generate vitality.
Lighting can change the appearance of the environment. Artistic lighting and color constitute dynamic and static landscapes of light, sound and color, and also show the small, sculptural and fashionable landscape garden lamps, which embellish the natural environment.
With the continuous changes in people's thoughts and lifestyles, lamps, light sources, materials, styles and design methods have undergone great changes. In choosing a suitable light source, in addition to economic factors, it is also necessary to consider the overall light environment effect and the reliability of the material texture, and also pay attention to the unity of the natural environment and lighting. Landscape lighting cleverly uses LED light sources to get rid of the traditional one-way design.
2. LED light environment
In order to improve visibility and appreciation. LED has been increasingly applied to signal and sign lighting, traffic lights on roads, induction lights in buildings and facade lighting that outlines the outline, and multi-color lighting in urban squares, gardens, and pedestrian streets. All of them are produced with ultra-high brightness LEDs. Their excellent energy-saving characteristics and extremely long service life are favored by lighting designers and owners.
Characteristics of LED light sources:
1. Good luminous uniformity, emission angle of 100o, luminous efficiency of 40-50Lm/W.
2. The average life of the light source is ≥100,000 hours, no serious light decay phenomenon occurs, luminous attenuation is ≤10%, and energy consumption is ≤24W.
3. The wavelength of light should be consistent, and the luminous intensity of the light color RGB should be able to change continuously
Red light: λ=630nm～650 nm
Yellow light: λ=585nm～593 nm
Green light: λ=525nm～528 nm
Blue light: λ=467nm～473 nm
And it can be programmed and controlled according to the overall requirements of the environment to produce an overall artistic landscape effect.
3. Hue
LED light-emitting diodes have soft light colors and have a strong artistic effect in square and garden lighting. It not only provides people with comfortable visual conditions, but also needs to coordinate various light colors to reflect the landscape lighting style, increase artistic beauty, and achieve the spatial landscape deliberately created by the design intention of the lamp to meet people's visual needs, aesthetic needs; psychological needs.
Because the color reflected by the night scene on the garden light sketches produces different tones, artistic appreciation, and cultural levels. Red is a warm color, which reminds people of the sun, red flags, and fire, and makes people feel enthusiastic, warm, and hot; yellow is a warm color, which gives people a noble, bright, and cheerful feeling; green is the main tone of the forest, full of vitality, which reminds people of green mountains and green waters, bright spring, and vigor, symbolizing youth, peace, and health; blue is an extremely calm color, which forms an elegant and tranquil atmosphere, which reminds people of the blue ocean and the blue sky; white is a cool color, which often reminds people of ice and snow, and cold, and gives people elegance, innocence, and peace.
