In terms of basic functions and light quality, Voltex Lighting's “Mellowlight†luminaires are ideal for bright and spacious rooms. This kind of luminaire is more focused on human perception. Compared to luminaires that are darker in color, they have a lighter appearance that makes the surroundings look brighter. The luminaire with BZ4 light distribution exhibits excellent light uniformity in the horizontal direction and high illumination in the vertical direction. At the same time, the blinds also provide a full range of glare control to prevent it from being reflected onto the workbench with the display screen. Obviously, the quality of light is far more important than the amount of light.
The design of the lighting system also needs to consider the key factor of cost-effectiveness. The LasconRCB "Mellowlight" luminaire consists of two T5 fluorescent lamps and Tridonic's PCA2/54T5ECO digital dimmable control unit. This type of luminaire is about 40% more expensive than a luminaire system equipped with a conventional magnetic ballast & T8 tube. However, SolutionStation research shows that although the cost of the system is relatively expensive, the cost can be quickly compensated for due to its low energy consumption and lower rework costs. Depending on the size of the external natural light available, these sources automatically adjust the light and dark, and are controlled on and off by an automatic detector. As a result, the new system can reduce maintenance and operating costs by nearly 65% ​​compared to conventional lighting systems; at the same time, it saves 50% of energy compared to older lighting systems. In the summer, the BP headquarters building in Cape Town, South Africa, was designed as a solar building. In the design of the entire lighting system, the use of natural light and energy conservation are two important criteria. The PCAECO digital dimmable lighting control unit and the DSISMART controller have successfully achieved this goal.
Energy-saving design for the BP headquarters building in Cape Town â–¡ Rui Gao Lighting Electronics (Shanghai) Co., Ltd. Xu Yan Fengguang can save energy costs by nearly 70%.
Thanks to the perfect matching control device, the life of the T5 fluorescent lamp is more than 16,000 hours, which reduces the number of replacements of the light source, and the maintenance interval is also lengthened, which in turn improves the environmental performance of the solar building. All luminaires are equipped with T5 fluorescent lamps for high energy efficiency and easy maintenance. The new luminaire system saves more than 20% compared to luminaires equipped with T8 fluorescent lamps and magnetic ballasts.
Some low voltage luminaires are used in public areas. The combination of an electronic transformer and a 35 watt source with an infrared layer is also very innovative. In this system, the heat loss of the transformer is about 8 watts lower than that of a conventional inductor transformer. Moreover, these 35 watt sources provide a luminous flux equivalent to a conventional 50 watt dichroic source. In other words, the power of each luminaire in the entire system will be reduced by 23 watts, which is equivalent to saving 37% of energy.
Operation and control
When selecting a control system, the primary consideration is whether the system is easy to maintain and easy to operate. In addition to the light quality and energy-saving effect, the system used in the building combines the simple design and convenient installation in the usual control and operation.
Unlike most other systems, the DSISMART controls the ambient brightness, which is the brightness of natural and artificial light sources in nearby areas. In addition to the photodetector, the product features an automatic detector that adjusts the off-delay time from 1 minute to 60 minutes.
Each sensor controls 4 luminaires in a 3mx2.4m ceiling grid area. Depending on the pre-set starter standard (eg illuminance 380lx, automatic detector using a 15-minute off delay), these luminaires are automatically dimmed or turned off by the sensor. The preset optical mode can be individually adjusted and set by a remote control, such as using a different personalization mode in a small office or in a conference room. It is also very convenient to return to the preset system mode, a simple one can be achieved.
For BP headquarters, in the future construction operations, not only the initial investment cost of the lighting system, but also the operating and maintenance costs during the life of the system must be considered. The innovative lighting scheme currently presented in front of us also makes the relationship between investment and income better handled, so that the lighting system of the whole building meets the current European standards, and the purpose of energy saving and consumption reduction is greatly realized. The environment is perfectly integrated and greatly enhances the comfort of the living environment in the interior space.
