Procurement of mercury lamps becomes difficult due to international treaties, switching to LED is an urgent need

The grounds set up at the school are mainly used by outdoor athletic clubs such as physical education classes and track and field clubs, and the grounds have long been equipped with lighting using mercury lamps. With regard to mercury lamps, the maintenance of the lighting environment has long been an issue, such as the ban on the manufacture, import and export of mercury lamps after December 31, 2020 under the international treaty "Minamata Convention on Mercury". There is a history of considering switching to lighting.

"We've been using it for a long time, and we were told that it would soon become difficult to use the mercury lamp itself. When we asked about switching to LED lighting within the university, we were able to get approval," said the office staff. The person in charge explains the circumstances. In the unlikely event that the ground could not be used, it would have an impact on club activities, so it was necessary to quickly switch to new lighting.

It is said that there has been a problem in the field that the illumination of mercury lamps is not sufficient. "We've been talking about the lighting being a little dark for some time. Also, some faculty members have been complaining about problems unique to mercury lamps, such as not being able to maintain brightness for a while after turning on the switch."

ShinyU satisfies robustness, brightness, and high degree of uniformity

Regarding the LED lighting, there were some problems when it was introduced to the classroom in the past, so it is said that emphasis was placed on robustness that is hard to break. In addition, as a precondition, it is said that the lighting must be brighter than the current lighting, and it must be guaranteed free of charge for at least five years. Especially for ground lights installed in high places that cannot be replaced easily, we wanted a stable product that is as hard to break as possible.

It was at this time that they came across ShinyU, a highly efficient industrial LED lighting system provided by Macnica. In fact, it all started when a Macnica sales representative happened to visit the school and suggested lighting to them. "I was a novice when it came to LEDs, and didn't know how to compare them. It was great to receive detailed information from Macnica, such as the characteristics of LEDs, an overview of Japanese Industrial Standards, and comparisons with other companies. To create a new environment, we contacted companies that handle sports equipment in general, companies that handle various electrical appliances, and construction companies, but the only one that specialized in lighting in the energy business was Macnica 's Circular Economy Business Promotion Department," said the administrative staff. Being able to obtain easy-to-understand materials about the characteristics and differences of specialized products also deepened the school's understanding of LED lighting.

After referring to the information obtained, we set the necessary conditions for bidding, such as illuminance, guarantee conditions, and the installation of guards assuming that baseballs and other objects will be thrown at them. “Because the ground is not specialized for a specific sport, we wanted something with a high degree of uniformity rather than uneven brightness.”

As a result of the final bidding process, ``ShinyU'' proposed by Macnica was selected as the solution with the highest cost performance.

Current operation

Realize various effects of lighting, such as environmental aspects such as cost and CO2 reduction, and student safety

Currently, a total of 30​ ​ShinyUs have been installed in two school buildings in a way that illuminates the ground from the top of the school building, and construction is carried out in about two days to minimize the use of the ground. In terms of actual brightness, the overall illuminance was more than doubled compared to the mercury lamp measured before installation, and more than five times the brightness when viewed in the darkest place. “Teachers are saying that it has made them much brighter. Right now, we are unable to do club activities until late due to the coronavirus pandemic, but we have received feedback that they would like to use it more.” In addition, compared to mercury lamps, the electricity cost for lighting can be reduced to about half, and as a result, it also contributes greatly to the environment, such as reducing CO2 emissions.

By switching to LEDs, it became possible to quickly grasp the on/off status of the lights, and it became possible to prevent forgetting to turn off the lights. "Even if the lights are turned off, they will become brighter as soon as they are turned on. This has also helped alleviate the anxiety of teachers who are worried about whether or not they should turn off the lights when they return home," said the administrative staff. It also explains that certain effects can be expected in terms of safety. “It will be easier to see balls and other objects, and it should also be effective in terms of safety, such as preventing injuries to students. Previously, the front of the clubroom was dark, but now that it is evenly lit, it should be better for crime prevention.” .

When changing the facilities in the school, there are many opinions, but it is said that there is no critical voice about the lighting change this time. For example, if you change the chair you sit on to a new one, you may have a reaction that although it is comfortable to sit on, the storage space for your feet will be narrower. “To be honest, it is difficult to satisfy all the teachers with regards to the facilities, but the lighting change this time was a rare case where there was no criticism at all. It is proof that

Regarding Macnica, after considering the usage environment of the school, LED We highly rate the company's generous support, including providing a wealth of knowledge and detailed materials at an early stage, from basic knowledge to important points for comparison. "LED They not only provided us with information about lighting, but also provided us with generous support, including measuring the illuminance in advance and making suggestions. I'm really grateful that you quantified the current situation, allowing me to explain things in an easy-to-understand manner to the office manager and others." In terms of robustness, he also felt a sense of security since the product was handled by a listed company. Furthermore, the company has received high praise for its extensive after-sales support, including providing detailed information about the installation conditions of the light fixtures that can be easily understood by other contractors.

Initially, proposals were made based on the JIS standard for lighting design for sports facilities, but the school ultimately chose something with high uniformity. "The school chose high uniformity with minimal unevenness in brightness, but Macnica was the only one to give us specialized proposals based on the JIS standard for lighting in sports facilities. We rate Macnica as a company we can trust in the sense that they can make a variety of proposals according to our needs," said the school's administrative staff.

from now on

Expectations for new solutions that lead to expansion of LED lighting and energy saving

Although the installation of LED lighting on the ground, which was carried out this time, has been completed, there are still some areas where LED lighting has not been introduced, including the main gate. As a school, we also have a position to play a role as a disaster prevention base in the region, so we will make decisions with the priority of investment in the entire campus in mind. When installing new LED lighting, ShinyU, which has a proven track record, can be one of the leading options.

Macnica is also currently proposing environmentally friendly solutions such as air conditioning equipment for gymnasiums from the perspective of energy savings brought about by LED lighting, and we are looking forward to solutions that will help solve problems in areas other than lighting.
