エコ・トラスト・ジャパン Company Profile

Eco Trust Japan Co., Ltd. (Minato-ku, Tokyo) will begin accepting orders for a new lineup of LED tube lamps designed for the elderly, in addition to traditional LED tube lamps. The size is equivalent to a 40-watt fluorescent lamp. As of 2022, the proportion of elderly people aged 65 and over in Japan accounts for about 30% of the population, and this ratio is increasing year by year. As people age, the lens of the eye undergoes yellowing, causing objects to appear yellowish compared to when they were younger, making it difficult to read newspapers, magazines, and books even under the same lighting. To improve the unique "visual perception" of the elderly, we have developed LED lighting that enhances "clarity and ease of visibility" by adjusting the emission spectrum to prevent white light from appearing yellowish. This product is particularly suitable for lighting in reading areas of nursing facilities and similar environments.

**Overview** Eco Trust Japan Co., Ltd. (Minato-ku, Tokyo; President: Akihiro Masumoto) has launched a plant cultivation type LED lamp in its highly regarded series of Japanese-made LED lamps. Utilizing LED elements developed by Toyota Gosei that are based on a purple color and closely resemble the solar spectrum, this new LED lamp contains a higher proportion of short-wave components and green light compared to conventional LED lamps. **Main Features** - By containing a higher proportion of short-wave components, it is expected to reduce diseases in seedlings and improve leaf coloration. - With a higher proportion of green light, it is anticipated that light will reach the middle layers of leaves even when they overlap. - The spectrum reproduces a gentle curve similar to sunlight, making it suitable as a light source for seedling growth and grafting care. - The lineup includes two types equivalent to 40-watt fluorescent lamps with color temperatures of 5000K (white) and 6500K (daylight).

Retrofit Solutions (Proposal for Eco-Friendly LED Lighting) As global warming progresses, energy-efficient LED lighting is gaining attention. There are mainly two types of LED lighting for conversion: "linear LED lamps" and "LED base lights." The features of linear LED lamps include "reuse of lighting fixtures" and "minimization of waste," making them an environmentally friendly LED lighting option that can reduce CO2 emissions by 80% compared to LED base lights. Now, let's estimate the CO2 reduction when introducing LED lighting from 100 fluorescent lamps. The waste from "linear LED lamps" amounts to 273 kg of CO2 equivalent, while the waste from "LED base lights," including fixtures and fluorescent lamps, amounts to 1,340 kg of CO2 equivalent. This shows that linear LED lamps can achieve an 80% reduction in CO2 emissions compared to LED base lights, confirming that they are an environmentally friendly LED lighting option. * The CO2 emission factor is calculated at 0.496 kg-CO2/kWh.
