We have adopted three newly designed lenses that enhance light extraction efficiency to spread LED light efficiently. These lenses are used and arranged according to the position of the LED modules in the light source section. The lenses on the inner circumference are transparent lenses with good transmittance that efficiently and evenly diffuse light. The two types of large lenses on the outer circumference, transparent and semi-transparent, diffuse light horizontally, reducing unevenness in the brightness of the cover. In addition, we have adopted Hitachi's unique technologies, such as a large heat dissipation structure that efficiently dissipates heat from the LEDs, which can cause a decrease in brightness, and the dispersion of heat and light through the size of the LED light source board and the arrangement of LED modules. As a result, we have achieved an industry-leading energy efficiency of 151.7 lm/W for applicable tatami mats up to 14 mats (approx. 22.5 square meters) and a maximum brightness of 6,099 lm within the applicable tatami mat display standard. Equipped with "Rakumie" for clear visibility of both text and colors. By adding blue-green light and increasing the brightness to 1.2 times that of full light, we have achieved a color rendering property of Ra90, which is higher than the average color rendering index Ra85 of full light, and equipped with "Rakumie" that makes fine text clearer and colors in photos more vivid.
