1. Functional principle:

Lighting design must meet the functional requirements, according to different

Space, different occasions, different objects choose different lighting methods and lamps, and

Ensure proper lighting and brightness. For example, the lighting design of the conference hall should adopt

Vertical lighting requires uniform brightness distribution to avoid glare, and it is generally appropriate to choose full light.

Area lighting; Shop windows and merchandise displays are usually used to attract customers.

Strong light is used to emphasize the image of goods, and its brightness is 3 times higher than that of general lighting.

~ 5 times, in order to strengthen the three-dimensional sense, texture and advertising effect of goods, the direction is often used.

The use of strong light and colored light improves the artistic appeal of goods.

2. Aesthetic principle Lighting is very important for decorating and beautifying the environment and creating an artistic atmosphere.

Means. In order to decorate the indoor space, increase the spatial level and render the environmental atmosphere.

It is very important to use decorative lights and decorative lights. In modern home architecture, shadows

Lighting is becoming more and more important in the environmental design of drama buildings, commercial buildings and entertainment buildings.

Part of the whole. Lamps and lanterns not only play a role in ensuring lighting, but also pay attention to it.

The shape, material, color, proportion and scale of lamps and lanterns have become indispensable elements in indoor space.

Less decoration. Lighting designers use light and shade, looming, modulation, intensity, etc.

Rhythmic control, give full play to the role of light brilliance and color, using transmission,

Reflection, refraction and other means to create a warm and soft, quiet and elegant, romantic,

Brilliant, magnificent, joyful, lively, mysterious and charming.

The alienated artistic atmosphere adds colorful interest to people's living environment.

3. The principle of economical lighting is not necessarily more, but the key to winning by strength is

Scientific and reasonable. Lighting design is to satisfy people's visual physiology and aesthetic psychology.

Need to maximize the practical value and appreciation value of indoor space, and achieve

The unity of use function and aesthetic function. Flashy lighting can not only add icing on the cake.

On the contrary, gilding the lily will cause power consumption, energy waste and economic losses.

It may even pollute the light environment and endanger health.

Due to the different requirements of use and resolution, the brightness standard of lighting is selected.

The standards used are also different.

4. Safety Principle Lighting design requires absolute safety and reliability. Due to lighting

Since the power supply, strict safety measures must be taken to prevent electric shock, open circuit, etc., so as to avoid accidents.

The occurrence of external accidents.

(A) the expression of light

1. Surface light performance Surface light refers to the luminous surface composed of indoor ceiling, wall and ground. sky

The characteristics of shed light are uniform illumination, sufficient light and various forms of expression. Ruyong

Fluorescent lamp ceiling, the light density must be consistent, to ensure that every space is full of light; and

If you use a large area of downlight ceiling, there are regular bull's-eye lights on the ceiling, just like the night sky.

Cloth; Another example is to design a lighting well combined with the ceiling beam structure.

Light is emitted from the well grid, forming a unique spatial effect. Wall lamps are usually pictures.

Used for film screening. Make the wall into a hollow double-layer sandwich wall, facing the wall on the monitor side.

A luminous wall is formed in which a plurality of glass frames are embedded, and a light projecting device is arranged behind the frames to form the luminous wall.

Luminous exhibition wall. Large light box advertisements also belong to this kind of lighting.

Ground light is to make the ground into a luminous floor, usually a dance floor, colorful luminous ground.

Board, its light and shadow and color change synchronously with the rhythm of electronic audio, which is greatly enhanced.

This paper introduces the artistic atmosphere of stage performance.

2. The so-called strip light refers to the light with light sources arranged in a long strip. Expression form

There are various changes, such as square, grid, bar, grid, ring (circle, ellipse

Circular), triangles and other polygons. For example, a flat ceiling with a light band on the periphery, the periphery

Embedded ceiling, inner frame ceiling, inner frame embedded ceiling, periphery

Ribbon floor, inner frame ribbon floor, annular ribbon floor, upper projection groove, ceiling lamp.

Grooves, concave light grooves for footings, etc. The long strip lamp has a certain orientation and is deeply loved by people.

Many public places are often used as guiding lighting in environmental design, and other geometric light bands are one of them.

Generally used for decoration.

3. Point light source Description Point light source refers to a light source with a small and concentrated light projection range. Because of its light

Strong brightness, mostly used in restaurants, bedrooms, study rooms, windows, stages and other places.

Connect lighting or accent lighting. There are many ways to express point light sources, such as top light source, bottom light source, smooth light source,

Backlight, side light, etc.

Top light-top-down lighting, similar to direct sunlight at noon in summer. Illuminated object projection

Small, strong contrast between light and shade, it is not appropriate not to do modeling light. Bottom lighting-bottom-up lighting,

Suitable for auxiliary light distribution.

Guang Shun-Illuminated from the front, the projection is very dark, and the color of the illuminated object is fully displayed.

But the three-dimensional sense is poor. Backlight-Illuminating from the right rear, illuminating the external outline of the object.

Clear and artistic silhouette effect is often used in photography and stage awning.

Light distribution mode.

Side lights-illuminate from left, right and left, right, left and right.

Object projection is clear, three-dimensional and rich in layers, which is the most acceptable light for people.

In this way.

4. Still lighting and mobile lighting Still lighting-the lights are fixed, but the lighting is still.

Change, the static light does not flash. Most indoor lighting uses stillness.

Lighting, this way of lighting, can make full use of light energy to create a stable, soft,

Harmonious light environment, suitable for schools, factories, office buildings, shopping malls and exhibitions.

Will wait for a place.

The flowing lighting-the flowing lighting method, with rich artistic expression, is a kind of dance.

Common means in TV lighting and urban neon advertising design. As used in the stage "chase"

Lights', constantly chasing moving actors, are like neon lights for advertising lighting.

The ground flow flashes and the color changes frequently, which not only highlights the artistic image, but also renders the artistic image.

Environmental artistic atmosphere.

5. Laser Laser is a light beam emitted by a laser. The medium that produces the laser beam is crystal.

, glass, gas (such as argon, krypton, He-Ne mixture, etc. ) and dye solution. some

In lighting art, some gas lasers have been used as light sources, among which He-Ne lasers are the most.

A commonly used one that produces red monochromatic light; Argon ion laser produces blue-green light and green light.

Light, these two wavelengths of light can be separated by diffraction grating to form two beams of light with different colors.

homogeneous light

Different dye lasers can generate any wavelength in the range of 400 ~ 750 mm as required.

A laser. However, dye lasers are all devices working in pulse mode, which must meet the requirements of

Use its laser or electronic flash as the driving source.

(3) Types and artistic effects of lamps The lamps adopt new technologies and materials.

With the different development, there are more varieties of colors and shapes, and the light, color, shape and quality are changeable.

Unlimited, lamps and lanterns not only provide lighting conditions for people's lives, but also are indoor environments.

An important finishing touch in design. Lamps and lanterns can be divided into the following types according to their installation methods.

.

Hanging type-commonly known as chandelier. General indoor space has general chandeliers; Festival lanterns (displayed on the Lantern Festival)

, used for luxurious and tall hall space; Palace lanterns generally adopt traditional classical style.

Plaid hall; Telescopic chandelier, using telescopic snake skin tube or telescopic chain as spreader, can

Adjust the height of lamps and lanterns as needed within a certain range.

The ceiling lamp is close to the ceiling. There is also a protruding ceiling lamp, which is more suitable for use.

Large, can be used alone or in combination, the former is suitable for smaller spaces,

The latter is suitable for a larger space; Embedded ceiling lamp, embedded lamp, combined type

Use gives the feeling of starry sky.

Wall lamps-there are two kinds of wall lamps and chandeliers, which are installed on walls and columns. wall

Lamps and lanterns are required to be decorative and suitable for all kinds of spaces. Floor lamp-also known as seat floor

Lamps and lanterns are local lighting in living rooms, living rooms, hotel rooms, reception rooms and other spaces.

Lamps and lanterns, one of the indoor furnishings, have the function of decorating the space.

Table lamp-a local lighting located in desks, coffee tables and low cabinets, is also a modern home.

One of the main interesting furnishings in the palace, the desk lamp has become a tool in modern hotels.

Unique decorative lighting means.

Special lamp-used for all kinds of special lighting lamps, such as spotlight for stage performance.

Lamps, return lights, skylight floodlights, rotating lights, beam lights, meteor lights, etc.

(4) Analysis of lighting design examples Lighting design must be based on the place of use and purpose.

Function, users, lamps selection, lamps installation, lighting communication art.

Different treatment makes it difficult to unify standards and scales. Now according to the relevant data, it is integrated.
