(2) Energy policy lacks incentives to develop energy-efficient lighting products. The promotion of power-saving products such as electronic ballasts lacks supporting design and publicity. In addition to the promotion and promotion of the industry, the government's energy conservation policy should consider subsidies for energy-saving products or explicitly eliminate high-energy-consuming products. The United States' comprehensive promotion of indoor use of electronic ballasts after 2002 is the best example.
(3) Major lighting-related components such as electronic ballasts and lamps; finished products such as lamps, etc., require mandatory standard specifications and complete inspections, and establish fair market order and business environment through fair penalties; The system of expulsion will result in a devastating competitive environment, unfair to the end consumers, and not conducive to the overall energy policy.
(4) Excellent lighting fixtures and light sources should establish an energy-saving label and environmental labeling certification system, which will be used in public projects and recommended to consumers. It will stimulate the development of lighting technology and meet the global trend of energy conservation and environmental protection.
(5) The advantages and disadvantages of the government procurement law are mixed. The lack of a fair competition environment and conditions for good products is not conducive to the operation of good manufacturers, resulting in the decline of the quality of public works. Therefore, public works should rely on the opinions or suggestions of the lighting industry to avoid the dangerous environment of the driver's driving safety such as the rapid road glare and tunnel black hole effect in Taipei.
4 Lighting engineering improvement strategy and direction
4.1 Redesigning living spaces that meet high lighting quality
The principle of lighting design should be the first to reduce the power consumption of lighting to the minimum without losing the quality of lighting, in order to save energy. Therefore, it is generally simple and feasible to compare the power consumption of lighting equipment with the power density per unit area by setting the reasonable illumination demand. If the total energy consumption (W) of the lighting fixture in the office is divided by the space area (m2), the unit lighting power density (UPD) can be obtained. Using electricity density as an evaluation criterion for lighting energy consumption, you can understand whether indoor lighting power consumption is reasonable.
The higher the illumination of the face, the easier it is to identify the environment and help read. The minimum illuminance required according to the work requirements can refer to the Taiwan Standard (CNS12112) or the international illuminance standard. However, according to the research experience and suggestions of the European and American related lighting associations, the most comfortable illumination for reading and writing is 1000-2000 lux; if it is difficult to achieve this For the most comfortable illuminance, the minimum requirement for maintaining eye fatigue for a long time should be 500 lux or more. Therefore, indoor lighting in large public areas of office buildings should be designed on a 500 lux basis to reduce the use of individual lamps. If you need to read the illuminance requirements of writing vision for a long time, the illumination of general office places and school classrooms should be maintained above 500 lux, and the power density UPD should be lower than 20 W/m2, which is in line with excellent lighting quality and energy saving. Green lighting target.
However, in fact, the design goal of the new office space may meet the requirements of this 500lux. For many years, the Taiwan Lighting Society has tried to promote the classroom lighting requirements to reach 500lux, but even the classroom lighting issued by the education department in March 2000 only provides no less than 350lux. Generally, the old buildings are only about 300 lux. In fact, it is difficult to call the environment of high lighting quality. The gap between urban and rural areas is large. Metropolitan areas and central units may be able to achieve this goal, and local units are far behind.
In some fine work and places where eyesight is particularly needed, general lighting and local lighting can be used, such as: design room, drawing room, etc., must have a higher illumination (1,500 lux), can be used for office basic lighting The design was changed to 500~750lux, and the table lamp was used to supplement the work table to 1,500 lux.
According to the experience of advanced countries, the 500 lux required for the 20-year-old benchmark, for every 20 years of age increase, the illuminance demand should be increased by 20% to 600-750 lux; therefore, the indoor illuminance standard can be reduced to 300 lux in the personal office. However, the desktop table lamp is used to supplement reading and writing lighting. Usually, the current 18~27W energy-saving fluorescent tube lamp is used. The illumination of the desktop is about 1200lux from the height of 40 cm on the desktop, which can reduce the illumination of large areas. Electricity, but produces the most comfortable reading lighting environment.
