Recently, Hitachi Electric has released LED ceiling lamps and fluorescent ceiling lamps for residential main lighting. The company plans to launch LED ceiling lamps on October 8 and the fluorescent ceiling lamps will be launched on September 10.
The LED ceiling lamp has a large amount of light and energy saving effect, and a large number of white LEDs are arranged in a ring shape almost entirely on the entire surface, and the light of the white LED is directed to the direct irradiation direction. By arranging the white LEDs in a wide range in a wide range, the irradiation area is enlarged, and the heat radiated by the white LEDs is not collected. In addition, in order to effectively dissipate the white LED, the white LED is mounted on a printed substrate using an aluminum substrate and connected to an iron casing. In this way, the white LED can be efficiently transferred to the casing while diffusing the heat of the white LED, thereby efficiently dissipating heat. The temperature of the white LED can be kept at a low level, so that the decrease in luminous efficiency due to temperature rise can be suppressed.
In order to avoid the "dot-like" feeling of the single white LED, the Hitachi is covered with a hemispherical transparent resin for each of the two white LEDs, and a lampshade that covers the entire light-emitting surface of the LED ceiling lamp.
The price is open and is divided into different price points with and without color. It is used for 14 tatami rooms, about 85,000 yen and 70,000 yen. The products for the 10 tatami room are about 65,000 yen and 50,000 yen, respectively, and the products for the 8 tatami room are about 55,000 yen and 40,000 yen.
The long life of 21,000 hours of the fluorescent ceiling lamp is achieved by using a coil (triple coil) that maintains the emitter (electron-emitting substance) to increase the holding capacity. In addition, the fluorescent ceiling lamp is equipped with two white LEDs as "LED auxiliary lights". LED Assist Lamps are used as safety lights that provide minimal brightness during power outages and power outages. The fluorescent ceiling lamp is equipped with a nickel-metal hydride rechargeable battery. Even if there is no power supply from a commercial power source or the like, the battery can be continuously lit for about 5 hours. A total of eight products have been prepared, including products with the [eco] button function of the LED ceiling lamp and products with LED auxiliary lamps.
