[High-tech LED News] Hitachi has expanded its lineup of LED ceiling lamps as an additional configuration for the standard elevator "Urban Ace". At the same time, it is also newly adopted to take advantage of the LED characteristics of the elevator to be controlled by the lamp, compared with the original ceiling lamp using the fluorescent light source, the annual power consumption can be reduced to a maximum of one-fourth. LED ceiling lamps start at 300,000 yen each, and strive to achieve annual sales of 1,000 baht.

This time, the product lineup has been expanded from one original product to four types by adding a newly designed LED light source ceiling lamp such as the entire ceiling. The interval between the original fluorescent lamp ceiling lamp from the elevator entering the standby state to the closing of the ceiling lamp was set to 3 minutes, and the new time of the Hitachi Production Co., Ltd. was shortened to 1 minute. Thereby, the annual lighting time of the ceiling lamp can be shortened to about one-half of the fluorescent lamp.

Up to 51 kWh, the annual carbon dioxide emissions will be reduced from about 90kg to about 22kg, which can be greatly reduced.
