Pay attention to the whole life cycle of LED products to realize green lighting

On "green lighting", the key is nothing less than the high efficiency and energy saving, environmental protection, safety, comfort and so on. According to the present situation of lighting technology and products in our country, it is still a long way to go to realize the real "green lighting". In recent years, combined with product development and engineering practice, the author for the realization of a number of green lighting experience is willing to share with you.

First, evaluation of a product is not close to or reach the green lighting standards, should not only evaluate the one or two prominent technical indicators, but should assess its performance in the whole industry chain, a comprehensive evaluation index of the whole life period. For example, the LED lamp luminous efficiency of 90 LM / W or even higher, life of 50 thousand hours or even longer, what is at what cost? The familiar, high light effect and long service life of the LED light source, depends more on the control of the junction temperature of radiator, so often become the huge LED lamps clear identification marks (with the information that LED lamp radiator average supplies for 75 g / w). The author thinks that we should focus on such a target, namely in the lamp of whole life, with a lamp unit value (as per million hours of total resources required to lumen) expenditures (such as capital, product consumption, consumption of non-ferrous metal etc.) to evaluate the advantages and disadvantages of lamps. This may guide practitioners to grasp the balance of various parameters. Assuming to consume more than the traditional light source of traditional lamps and more aluminum radiators and other non-ferrous metal resources, in exchange for lamps, "the use of" electricity consumption, whether there is a reason to call it "carbon transfer"?

Second, healthy promotion of green lighting project, and improve the timely amendment depends on the relevant industry standards. Lighting is a service for the people to the continuous improvement of the quality of the light environment, the quality of service requirements, so the relevant standards are constantly adjusted. For example, GB500342004 and its first generation standard (GB5003492, GBJ13390) compared to the illuminance standard is greatly improved, as the general office, the provisions of the GBJ133-90 median of 150 lux, the new standard is 300 lux. This is the "on-demand lighting" due meaning. But it is undeniable that the demand for light environment, there is a normal demand, there are differences in demand...... This requires the guidance of the relevant standards, in other words, the lighting is for people, but also for the low carbon life services. According to "China Construction News" reported that the China Academy of building research has begun to "architectural lighting design standards GB50034-2004" to amend the views of the consultation, the author is full of hope.

Here also proposed a standard for lighting design of lighting products and application of engineering practice guidance problem. In the engineering practice in the past few years, the author finds that there is a considerable gap between the running state of the underground parking lot and the standard requirements. The main performance of the design and construction to meet the standard requirements and passed the acceptance, but in order to save electricity, during the operation of the user to dismantle the light or reduce the number of lights. In the underground parking lot ground illumination indicator for example, "GB50034-2004" architectural lighting design standards for not less than 75 lux, but in practice the implementation is not ideal, such as a hotel and measured value is 12 lux, a school for 30 lux, and the highest for an agency, is as high as 110 lux. The above example shows that the actual operation of the construction of the standard and the actual deviation. In the standard, whether through scientific measurement of human behavior model, confirm the different demand for the public places lighting, which can confirm and quantify the actual demand of the so-called "dormant" people under the lamp, making "on-demand lighting" beyond individual engineering practice, to express clearly and index the system of scientific and reasonable design, construction and operation to better guide the architectural lighting. Thus, the standard should be respected and implemented, users are more willing to use energy-efficient lighting products and operating mode. At the same time, it is possible to define the concept and extension of the intelligent lamps and lanterns, in order to regulate the healthy development, and gradually standardized, and thus become the industry and the community wide choice.

Finally, one of energy-saving lighting products "reason" use, that is to say, energy-efficient lighting products in any case, there is a reasonable use of the problem, not the herd instinct, without choice, blind promotion.

It can be said that "green lighting" is a need for long-term pursuit of the goal. As "according to the need of illumination and advocate" the concept of active practitioner, Huawei Kidd lighting technology (Beijing) Co., Ltd. to provide lighting technology, energy saving and environmental protection products and services to the society at the same time, constantly questioning and thinking about the connotation of green lighting, in order to make a conscious practitioner, the successful state to make their technology and constantly close to the green lighting products.
