Characteristics and control of natural lighting

Natural lighting is the collection of natural light through the lighting cover, refracted and transmitted through the pipe, and the natural light is directed into the room, and the whole system can be called the light guide pipe system.

And it can adjust the brightness of the sunlight, generally if you don't want the light during the rest time, you can use the regulator to turn the sunlight.

Block, similar to the switch attention.

Laino building materials adopts natural smoke exhaust or mechanical smoke exhaust to exhaust the fire smoke from rooms, corridors and other spaces to the outside of the building, which is divided into natural smoke exhaust system and mechanical smoke exhaust system.

Side window lighting, skylight lighting.

The advantages of side window lighting: simple structure, convenient layout, low cost, clear directionality of light, conducive to the formation of shadows, suitable for objects with a strong sense of three-dimensionality, and outdoor landscape. Cons:

The illumination distribution is uneven, (the illumination is high near the window, and the horizontal illumination near the window decreases quickly.) (When the lighting area is equal and the elevation of the bottom of the window is the same, the square window has the largest lighting (referring to the sum of illumination of each point in the room), followed by the vertical rectangle, and the horizontal rectangle is the smallest.) However, from the perspective of illumination uniformity, the vertical rectangle has the best uniformity along the depth direction, and the horizontal rectangle is more uniform along the width direction.

The main factor affecting the uniformity of horizontal lighting in the interior is the wall between the windows. The wider the wall between the windows, the worse the lateral uniformity.

The biggest advantage of the skylight is that it is conducive to the amount of light and the illumination is evenly distributed. Sunroof form:

Rectangular skylight: This type of skylight is located high and is less prone to glare. To avoid direct sunlight to reach the room.

Inside, the glass of the skylight should preferably face north-south.

Transverse skylight (transverse rectangular skylight): The glass of this type of skylight should also face north-south.

Zigzag skylight: This kind of skylight has a sloping ceiling as a reflective surface, which increases the reflected light, and the lighting efficiency is higher than that of a rectangular skylight, and the window generally faces north.

Flat skylight: characterized by high lighting efficiency, but easy to pollute. However, attention should be paid to the prevention of light pollution, direct sunlight and condensation. Dispersed arrangement, the required area of the flat skylight is minimal. The rectangle is the largest.

Pit skylight: This type of window is mainly used for ventilation and lighting.

Hello dear! We'll be happy to answer for you. The main factor affecting natural lighting is the movable A:

Hello, the main factor affecting the lighting of natural roller skating is the movable doors and windows, 1. The spacing between the buildings is the main factor affecting the lighting effect. According to the relevant regulations: the spacing between buildings should be based on the winter solstice sunshine time of not less than 1 hour (the window on the ground floor of the house).

Among them, the calculation formula of the building spacing is: the building spacing The height from the outdoor lawn of the building to the eaves of the house tan(a)a is the solar altitude angle at noon on the winter solstice. 2. The design of the house type will also affect the lighting effect of the house, and the house type with better lighting is generally square and transparent.

For a square house, the design of its bay and depth will also be more conducive to lighting. Buyers can pay attention to the fact that the sunlight entering the room will weaken with the increase of depth. That is to say, the larger the house and the smaller the depth, the better the lighting of the Tongzhi house; The lighting effect of small bays and large depths will definitely be affected.

3. The height of the floor will also have an impact on the lighting and waxing, generally speaking, the small high-rise residential floor should not be less than 3 floors; The floors of high-rise residential buildings are better lit by the middle floors. At present, the houses in the market are mainly high-rise residences, so it is best to choose the area of 1 3 to 2 3 of the total number of floors when buying a house, and the lighting in this area is generally better.

The condition of natural lighting in the room depends on the following:

Codes for building daylighting design and maintenance and management of daylighting facilities. Reasonable lighting standards play an important role in meeting the requirements of production and life, protecting eyesight and ensuring safety. Lighting standards mainly include lighting coefficient and lighting quality.

The lighting coefficient refers to the ratio of the natural illuminance of a certain point indoors to the horizontal illumination of the outdoor and unobstructed places in the open air on a completely cloudy day.

The larger the value of the lighting coefficient, the better the lighting effect. The quality of daylighting depends not only on the illumination of the surface of the object to be recognized, but also on the directionality of the light projected on the surface of the object, the brightness contrast between the grinding of the object and the background, the presence or absence of glare in the field of view, and the brightness ratio between the surfaces of the various envelopes in the room.

The methods for determining the daylighting coefficient can be divided into two types: indirect method and direct method. The indirect method stipulates the ratio of window area to floor area according to the room for different purposes. This method is simple and suitable for standard buildings and prefabricated buildings, but this method does not take into account factors such as the amount of indoor lighting, the distribution of light, and the light loss caused by window dispersion.

The direct method specifies the value of the daylighting coefficient of the room. This method compensates for the shortcomings of the indirect method and is the main method adopted by countries around the world.

China has formulated the "Lighting Design Standards for Industrial Enterprises" (TJ33-79). This standard uses the diffused light in the all-cloudy sky as the light source calculated in the lighting design, and the lighting coefficient is used as the quantitative evaluation index of the lighting design. According to the photoclimatic characteristics of most areas of China, the illumination (5000 lux) and lighting standard level of outdoor Linshi Zhongdoujie are specified. The uniform value of daylighting coefficient is specified, and the calculation method of daylighting coefficient and the parameters required for calculation are proposed.

Hello, dear. What is the main purpose of indoor lighting? Mainly on the ground, wall, and top.

First, if you have poor lighting, then it is recommended to use white as the main rock pure color in the use of color, and now the room height is not as good as before, so the white used on the top is a good choice. I suggest adding one or two drops of blue essence to the white paint for the wall color of the living room, using a very light way to distinguish the white, adding a change to your own space, and at the same time, the extremely light blue can enhance the lighting of the room, which cannot be seen without the premise of using an auxiliary light source. The bedroom is a private space, then the top is mainly white, the wall is made of light purple or light red, and the technique is the same as the living room, so that the whole can be used to distinguish the indoor space of the silver jujube shirt with a very small color transition, and you can make better use of indoor lighting.

Second, if you use a white baseboard with this change, the indoor unity will be stronger. Thirdly, I like the color of the light blue cavity of the door, but it is better to spray the paint in the use of paint, because the way of brushing will reduce the effect of the interior. Fourth, the ground needs to be lighter and brighter.

Kiss. The above is my answer, I hope it can help you, if you have any other questions that need to be consulted, please continue to ask, dear.

1. Face width and depth: The width and depth of the façade refer to the depth of the house. The larger the width and the smaller the depth, the better the lighting, while the smaller the width and the deeper the house, the better the lighting.

2. Building spacing: Building spacing is also the main factor affecting the lighting of the house, so consumers should observe when the sunlight can shine into the room in the morning before buying a house, and what time is there no sunlight in the afternoon. Users who are not existing residents can stand outside and observe if the distance between the two buildings is reasonable.

3. Floor height: Under normal circumstances, small high-rise buildings should buy houses with more than three floors. High-rise buildings should be purchased with more than six floors, and consumers need to buy a house based on the actual height of the building and the spacing between the buildings.

4. House orientation: The direction of the house is naturally south, followed by the east-facing direction, and the living room and master bedroom are facing south when choosing the house type.

In fact, house lighting can also affect people's mood, so indoor lighting is very important, and the above is an introduction to the factors that affect indoor lighting, I hope it will help you buy a house.

1. Floors and floor spacing.

The floors and floor spacing can be observed together to observe the lighting of the house more intuitively. Generally, the standard for building spacing in towers is building height: building spacing = 1:

The standard of floor spacing of slab buildings is the building height: building spacing =, the smaller the ratio, the larger the building spacing, the better the lighting, if the building spacing is not even up to the basic standard, it will cause the middle and low-rise residents to be unable to ensure enough light time, affecting the quality of life.

In the case of the same spacing between buildings, the higher the floor, the better the lighting, the less obscured parts, and the longer the daylight hours. However, it is not good to have too high floors, because the indoor temperature of high-rise residents will be higher than that of middle and low-rise floors due to severe sunlight exposure in summer.

Second, the distribution of external buildings in the community.

External object occlusion is also an important factor affecting daylighting. In addition to the buildings, there will be other planning facilities in the community, if the lighting surface of some rooms is accidentally blocked, it will also cause the sunlight to not shine smoothly into the house. If the house is located on the outskirts of the complex, you should also observe whether there are buildings that are too tall on the outside of the complex to block the light.

3. The orientation of the house.

According to the advantages and disadvantages of lighting, people should buy houses in the order of south, southeast, east, southwest, north, and west. For the current high-rise tower residence, basically can not do every room in the interior facing south, then the appropriate way is to arrange according to the overall layout of the house, because the place where the family stays for a long time is the living room, so to ensure the lighting of the living room first, followed by the bedroom, and then other living space.

Fourth, the lighting surface is wide.

The face width can be explained in two ways. One refers to the length of the exterior wall surface that can be used for lighting, which can be called "lighting width". The other refers to the width of the room, which corresponds to the depth, the length of the room is called the depth, and its width is called the width of the face, that is, the opening room.

For buyers, for a room with a defined area, the depth is small, the lighting surface is wide, and the better the lighting, the more comfortable it is to live.

For residential buildings, reasonable design should meet the requirements of three aspects: first, it must ensure that there is a "wide lighting surface"; Second, the "lighting surface width" is better to face south; The third is that the "lighting width" should have a certain proportion with the room. Under the premise of "lighting width", there are three indicators of "room width":

The living room should not be lower than the meter, the bedroom should not be less than the meter, and the kitchen and bathroom should not be less than the meter.

Fifth, the layout of the windows.

Even if the floor, spacing, and floor type of a house are very good, it is impossible to get light smoothly without reasonable windows. In terms of window layout, buyers should observe the size of the windows and whether they are adequate (e.g. kitchen, bathroom, etc.). Buyers can tell the relevant information by the window markings on the floor plan.

I hope mine can help you.
