Energy saving problem in living space of interior lighting design

Global warming has become a problem can not be ignored. Every moment of climate phenomena happened around us. The United Nations intergovernmental panel on climate change report that led to the main cause of global warming is human activity. Energy saving become the norm in our actions, blindly requirements and energy saving, however, ignore the environmental protection and human nature, will let the energy conservation. The concept of green lighting is the embodiment of this principle is put forward. The so-called green lighting is to save energy so as to achieve the role of protecting the environment. Therefore, in building lighting design, and must follow the relevant state laws and regulations, the implementation of green lighting. Will begin work on a lighting energy-saving design methods in the analysis of the following:

a, building lighting design standard

energy-saving design is to produce visual conditions for the lighting and equipment for the design of energy saving, thus to protect the environment and in accordance with the purpose of the human. How to achieve energy saving purpose, in the national standard 'building lighting design standard' GB50034 - 'Lighting energy-saving assessment in 2004' in the section with clear rules. It wrote to value evaluation index for the lighting energy-saving lighting power density ( LPD) The index refers to the lighting installation power per unit area ( Including the light source, ballast or transformer) To calculate, the unit is W / ㎡. The LPD value in design provides a reference for us. We can according to the requirements of the field intensity of illumination, on the basis of lighting power density value distribution of light source. Achieve the rational utilization of energy therefore, we must fully understand the field. According to the actual situation to adjust the intensity of illumination. For example, housing Chinese restaurant lighting design. General restaurant features is to meet members of the family have dinner and communication. Thus lighting design should consider the two functional design lighting solution, and then in LPD value for reference, reasonable decorate lighting distance and intensity.

2, make full use of natural light in order to achieve the effect of energy saving

use sunlight to reach the role of lighting is undoubtedly the most energy saving, color temperature and sunlight contains threshold than any kind of artificial light. This feature enables lighting objects presents more abundant surface color and texture. Moreover, in the sunlight with ultraviolet light and other radiation, can effectively kill bacteria, so the sun use value is priceless. How to make use of the sun in interior lighting design in order to achieve the effect of energy saving and environmental protection?

　　1. First coefficient of the daylighting of the room or the area ratio of light inlet window should comply with the 'building lighting design standard', at the same time make full use of indoor smooth reflective, can effectively improve the utilization rate of light, such as white metope of reflection coefficient of up to 70 ~ 80%, can have the effect of energy saving.

　　2. Also should make full use of natural light on electrical control, strong light can be turned off when the window part of the lamps and lanterns.

3, according to the requires the use of energy-saving lamps and ballast

use efficiency of the efficient lamps and lanterns of the light source can effectively save energy. Efficient light source refers to the luminous efficiency of K, it represents the luminous flux emitted from light source consumption per unit of electricity. That is to say, in the unit, on the basis of constant power, luminous efficiency of the bigger the province electricity. Contrast the following form:

contrast the above table, we found that the light of incandescent lamp visual effects in 15. 5 lm/W, and the fluorescent light visual effects is 69 lm/W, visible, fluorescent lamp to some extent is much more to save energy than incandescent bulbs.

in addition to the choice of lamps and lanterns can help us save energy, choose correct ballasts can also can do it. Divided into two major categories of the main points of gas discharge lamp ballasts, electronic ballasts and inductance ballasts. Can make the tubes under the condition of high frequency electronic ballasts improve lamp luminous efficiency and reduce the loss of ballast itself, is beneficial to energy saving, and light stability, eliminates the stroboscopic and noise, is helpful to improve the lamp life. In the operation, can make the fluorescent total power by 20%. Match with T5 thin tube diameter fluorescent lamp electronic ballast instead of T12 coarse diameter fluorescent lamps with ordinary inductive ballast, by using eight hours a day, a year can be (23 degrees: Does not include the weekends) Energy-saving effect is very considerable. Inductance ballasts at the same time also should choose energy-efficient, so that the total input power of lamps and lanterns again again by 20%.

4, choose reasonable way of lighting control

there are two main types of indoor light source, one is natural lighting, second is the power supply system to provide artificial light. Reasonable layout and control both the light source can effectively reduce energy consumption. There are several principles can be used to handle.

　　1. In has good natural lighting conditions, such as no special need to make the most of natural light 2. In the residential building corridor, staircase and so on the night intermittent illumination need, install sound electric self-extinguishing switch 3, etc. There are two or more light control switch, should not be greater than 2 4. Install can control the intensity of light in the switch control switch, so that the light intensity of regulation to reduce electricity usage

the complimentary in this article, through summary of indoor lighting design of energy saving and environmental protection measures and methods, in order to create a comfortable, healthy environment lighting solution for improving the production, work, study and life as the service quality and efficiency. The research will lead us to better establish harmonious relationship with nature, reduce resource waste and environmental damage.
