2 terms and symbols

2.0.1

Luminair lamps

An apparatus for collecting, distributing, or changing the direction and distribution of light energy, including all parts of a light source, a light source, a light source, a light source, a light source, a light source, a light source.

2.0.2 light distribution curve luminous intensity distribution curve

It is a curve that describes the luminous intensity of lamps in different directions. Usually the light distribution curve is the total luminous flux of 1000 LM to draw, so when the flux is not 1000 LM lamp, luminous intensity should be based on the flux ratio corrected.

2.0.3

Illumination (E) Illuminace

The flux is facing the unit area of the object is reflected, lighting, unit for Lux (LX).

2.0.4

Brightness (L) luminance

A light emitting surface unit projection area in the direction of observation, is a parameter that reflects the human eye to bright objects, as Nituo unit (NT). (NT = 1 1 cd/m2)

.

2.0.5

Floodlight floodlighting

The illumination of an object with a single or group of projecting light from the outside, so that its brightness and hue are different from those of Zhao Mingfang

Type.

2.0.6

Outline lighting contour lighting

With the way of lighting incandescent bulbs, lamp, neon lamp or other linear light source, the outline of the outline of a building.

2.0.7

In the light of lighting illumination with inner lighting sources

The illumination of the artistic beauty of the building is illuminated by the light source of the building by the indoor light source.

2.0.8

1ight pollution light pollution

An environmental phenomenon caused by uncontrolled light energy, which is caused by an inappropriate intensity, direction, tone, or change of rhythm, which causes discomfort or affects the normal activity of the human body.

2.0.9

glare

Glare

Direct light,

In the field of vision, the light reflected from the object of brightness or brightness contrast is called glare.

Glare not only affects

Normal lighting and sound effects, cause visual discomfort even when its visual disability.

2.0.10

Color temperature colour temperature

It is a measure of the scale of light and color, which is based on the blackbody at different temperatures of the light color, the blackbody in the absolute temperature K to measure the unit Kelvin degree (K).

2.0.11

The color index colour rendering index

Under the illumination of the measured light source and the standard light source (under the consideration of the color temperature), the degree of conformity of the object is presented, which is usually expressed in the letter Ra.

2.0.12

The sensitivity of sensitivity

The ratio of the minimum fault of the protection device to the action value of the protective device.

2.0.13

Harmonic harmonic

The number of integers in the Fu Liye series of the periodic quantity is higher than 1.

2.0.14

The United earthing grounding combined

The grounding of a variety of different uses is connected to a common grounding device.

2.0.15

Suspend earthing suspension grounding

The whole or part of the circuit is connected with the grounding part at a constant potential, and does not constitute the grounding mode of the grounding current loop.

3 city landscape lighting planning

3.1

general provisions

3.1.1

Urban landscape lighting planning is part of the whole urban construction planning, but also a system engineering. Should co-ordinate arrangements for the implementation of a comprehensive organization.

3.1.2

Urban landscape lighting planning by the city's overall urban landscape lighting planning and a single scenic spot or scenic lighting planning two levels.

3.1.3

Should be based on the city landscape lighting planning, scenic spots or individual according to the specific situation and landscape features, as well as local economic and technological development, to develop a single scenic attractions or lighting planning.

3.2

Principle

3.2.1

The planning of urban landscape lighting shall conform to the requirements of the whole urban construction plan and the provisions of the international lighting Commission on the standards, specifications and technical documents of the urban nightscape lighting.

3.2.2

Urban landscape lighting planning should be adapted to the city's historical and cultural characteristics, which constitute one of the manifestations of "light culture" which is in line with the characteristics of the city and has obvious characteristics.

3.2.3

Urban landscape lighting planning should emphasize the visual effect of the city at night, to focus on the highlights, light shadow, clear, both changes, but also a unified and harmonious, harmonious and beautiful.

3.2.4

Urban landscape lighting planning should reflect the organic combination of lighting technology and art, so that landscape lighting is not only beautiful, but also has cultural taste.

3.2.5

Urban landscape lighting planning should fully reflect the requirements of saving energy and saving resources of green lighting.

3.2.6

Urban landscape lighting planning should follow the principle of "people-oriented" and protect the natural ecological environment.

3.3 overall planning

3.3.1

City landscape lighting planning should make the landscape of the City show point line combination, plane, elevation and air combination should be coordinated, landscape rich, light color, moderate level of scattered light, both static and dynamic binding, prominent theme, the effect of touching, forming the overall landscape effect, should have modern city characteristics and high grade culture.

3.3.2

The overall planning of urban landscape lighting should be involved in the city outline, road landscape, urban signs, water landscape, regional landscape and other special planning.
