Basic knowledge of lighting design

Lighting design not only to know the light source and lighting, but also in-depth consideration to the nature of space, lighting lighting objects (building design, construction, and interior materials, workmanship, color etc.) and many visual factor psychological and physiological characteristics of people.

Lighting design of the basic knowledge of

In fact, the 1 lighting design involves the whole architecture and space, including how to make the building space and lighting due to add beauty, how to make people touched by the effect of lighting design has already exceeded the scope of lighting.

2, United States is the oldest of the lighting designer as a kind of occupation (1940s), Japan (1970s).

3, Richard Kelly, a famous American Lighting Design (home lighting design of the father). The main works: Texas Ford worth the Gimbel Museum of Art (and using natural lighting and artificial lighting design; lighting design) entrance hall of New York West Graeme Picasso building murals across the wall of the;

4, Richard. Kelly's lighting technology and create a happy and comfortable: (1) the overall space completely cover the warm and peaceful environment lighting; (2) the object of high brightness lighting lighting more clear; (3) flashing brilliant, let a person have the entertainment mood lighting.

5, lighting design not only to know the light source and lighting, but also in-depth consideration to the nature of space, lighting lighting objects (building design, construction, and interior materials, workmanship, color etc.) and many visual factor psychological and physiological characteristics of people.

First, the dark and light akimitsu

1, light is not only the human visual perception of light, also includes the human visual perception to the infrared and ultraviolet light. We refer to these as electromagnetic waves, and the different wavelength ranges determine the nature of the various wavelengths of light.

2, and visible light wavelength domain adjacent and wavelength domain than visible light wave length is the same than visible light, ultraviolet radiation, long wave infrared wavelength domain is. The infrared ray mainly has the thermal effect; according to the different wavelength, the ultraviolet ray can produce the sunlight sterilization and the luminescent effect of the phosphor.

3, reduce meaningless lighting, highlight the part, improve the environmental atmosphere and visibility to highlight the overall lighting effect. Shadows and darkness.

4, lighting techniques and methods vary with the different types of light source. The utility model can reflect, transmit and refract the light emitted by the light source by the different materials used in buildings and lighting lamps, thereby greatly changing the nature of the light emitted by the light source.

5, transmission material, a translucent paper lanterns, paper sheet, paste marble, translucent plastic, translucent glass, wax stone etc.. Transmission materials are mainly used for lighting fixtures. Due to the different production and processing technology, as well as the use of different light sources, can get a unique light source. The primary light source of the incandescent lamp and fluorescent lamp, the surface of the irradiated object can also be a light source due to reflection and transmission, which is called the two light source.

6, high light, refers to the spotlight that the illuminated object reflection, more prominent than the surrounding bright light, the visual effect is better; the wall, the wall surface such as washing, have bright and uniform lighting light (for smooth walls, marble and granite ground with walls must be light emitting angle can not iridescent reflected light; glare and smooth calm while on the same wall, if a certain distance away from the wall of the lighting lamp will be forced into wall irradiation, the walls, the ice cold stiff bright reflected light).

The second chapter brightness and color

1, in some cases can be regarded as the illumination brightness, but does not mean that the illumination to make people feel bright space. The range of illuminance used by lighting designer and lighting engineer is 0LX ~ 100000LX. Illuminance is measured by a illuminance meter, mostly on the horizontal surface of the floor and table.

2, & Jinye phenomenon, 170 years ago, the S & Jinye found in the bright place, orange and yellow and blue in the same illumination appear more bright, but in the dark blue is easier to see.

3, brightness, cd/m2 - Candela / m2.

4, if the light emitting surface and separated into small parts, then the beam is relatively dispersed, which has important significance in the lighting performance. A high wattage lamp installation, installation of a number of lamps as low wattage, and work on the configuration of the lighting design, lighting will be superb performance.

5, visible spectrum, 380 ~ 780nm (10 nm, 9 meters). The visible spectrum can not only be produced from the sun, but also can be used in the general lighting sources such as candle light, incandescent lamp and fluorescent lamp.

In 6, general lighting lamps, the long wavelength in the vicinity of lights and incandescent lamps as red, light color warm white, blue as in the vicinity of the short wavelength light source color cool white. With such a continuous spectrum of light color is called color temperature (unit: K), in the daily lighting space, about 2000K ~ 6500K of light and color can be controlled.

7, the light source color temperature lower warm red more, higher color temperature, more blue.

8, of historic buildings uses warm color more light of low color temperature; new buildings use of white light with high color temperature, and make it more eye-catching.

9, source nature of the object colors is called color. The average color rendering index (CRI) shows that the highest color rendering index is 100.

The third chapter source world

1, new light source: LED (light emitting diode); EDL lamp (electrodeless lamp); EL lamp (electroluminescent lamp).

2, LED lights are red, orange, green, blue four colors. A white light source is obtained by combining blue with phosphor.

3, main indoor light source: tungsten halogen lamp and fluorescent lamp; the main light source for outdoor use: high pressure sodium lamp, metal halide lamp, high pressure mercury lamp, lamp (searchlight) such as hernia.

The fourth chapter lighting

1, the choice of lamps points: (1) the price (2) delivery (3) dimensions (4) materials (5) work (6) light source (7) notice.

Have a significant impact on the visual effect 2, the size of the space of the whole lamp.

3, understand the light distribution curve diagram, figure out how light emitted from the lamp. Light distribution curve can be described as follows: (1) what is the direction of the light emitted from the luminaire, and how much light intensity.

, 4 example: if the lamp luminous flux is 5000lm, then the longitudinal axis of the light intensity value (CD) will be multiplied by 5 times. Lamp vertical down value of about 420cd. Well, 420cdx5 = 2100cd here, illuminance = intensity I (CD) / distance d2 (M2). (average illuminance = luminous flux F/ area m2).

5, downlight, do light wall, the wall is not smooth.

6, chandelier, (1) general table is installed above a chandelier chandelier, table size is recommended 1/3 to the longitudinal length of the amplitude of 1/2. (2) the installation height of the lamp is more suitable than 60cm above the table.

7, ceiling lamps.

, 8 spotlights, (1) installation spotlights are direct, slide, rail, soft clamp type etc..

9, wall lamp.

10, placed type lamps.

11, track lighting, suitable for shops, clothing stores, hotels, shopping malls, jewelry stores, entertainment venues, restaurants, exhibition venues etc..

12, grille fluorescent lamp.

13, outdoor lighting, (1) for small objects are illuminated by halogen tungsten lamp light, illuminated by HID lights too large objects. (2) lamps used in coastal areas must be corrosion resistant.

The fifth chapter lighting design process

Most of the work 1, lighting designer is the same architect and interior designer to complete the.

2, lighting design process: (1) appoint the design budget, design scope, design period, customer requirements] (2) the basic plan to master the construction space, the effects of sunlight, furniture and interior decoration materials and configuration] (3) the basic design of light image, using computer graphics, model the simulation calculation; illuminance; lighting lamps selected; configuration; (4) the implementation of budget] [with the design architecture, interior design, budget changes, review of research; decision, lighting lights, lighting dimming program (5) [] supervision and management of light focusing, quality inspection lamps (] 6) record [photos], determination of illumination.

3, the utilization rate of lighting, lamps emitted from the beam refers to how many percent reached the floor or work table: average illuminance (x = rate maintenance factor using 1 light flux x lamp x lighting / floor area).

The sixth chapter mainly lighting space

1, landscape lighting (1) light source and lighting (2) to establish the concept of (with the smallest possible illumination to obtain high lighting effect)

In any case, 2, lighting lights do not directly into people's eyes.
