Hitachi electric released on the brightness of the LED lamps and high efficiency long-life fluorescent lamps

Hitachi was released in August 30, 2011 for the main residential lighting LED lamps and fluorescent lamps. LED ceiling lamp is characterized by easy to indoor white LED light irradiation, the pursuit of brightness performance; fluorescence characteristics of ceiling lamps, comprehensive efficiency (with input power divided by the total luminous flux of the lighting value) can reach up to 128lm/W, rated life of lamps up to 21 thousand hours. The company plans, through the listing of LED ceiling lamp, involved in the late LED lighting business as soon as possible to catch up with other companies. Fluorescent ceiling lamp by improving energy efficiency, to attract consumers to increase awareness of energy saving. Time to market, LED dome light for October 8, 2011, fluorescent ceiling light for the year September 10th.

Directly to the indoor lighting to enhance the brightness of the white LED irradiation, also take measures to reduce the "dot"

LED ceiling lamp to take into account the large amount of light and energy saving effect, almost in the entire surface are arranged in a large circle of white LED, and white LED light toward the direction of direct irradiation (indoor direction). By expanding the area of the white LED in a wide range of annular areas, the heat emitted by the white LED is not aggregated. In addition, in order to make the white LED effective heat dissipation, the white LED is installed on the printed substrate with aluminum substrate and connected with the iron material shell. As a result, the diffusion of white LED heat can be effectively transferred to the shell at the same time, which can be highly efficient cooling. The temperature of white LED can be kept at a low level, so it can reduce the luminous efficiency caused by temperature rise.

If the white LED light toward the direction of direct irradiation, it is easy to appear a single white LED light emitting point to point like". To avoid this problem, Hitachi electric appliances for each of the two white LED covers a hemispherical transparent resin, also set up to cover the whole LED ceiling lamps illuminating surface shade. As a result, the diffusion of each white LED light, eliminating the point like. In order to eliminate the point of view, the best location of the white LED, the semi transparent resin and the cover of the lampshade are covered.

LED ceiling lamps, a total of three types, can be used for a maximum of 14 tatami room size (1 tatami is equal to 1.62m2) and 10 tatami and 8 tatami room, each type were prepared with color and without color varieties, so a total of 6 products. With the function of the color of the product, one of the 2 white LED under the cover of the hemispherical transparent resin for the bulb color varieties, through the adjustment of ordinary white LED and the light bulb white LED light to light. The number of white LED installation, for a maximum of 14 tatami rooms were 192 varieties. White LED is a chip with three blue LED chips. About the brightness, LED ceiling lamp input power and luminous efficiency, "is to make the final product of the adjustment, so the numerical also released inconvenience" (Hitachi). However, "strive to be on the brightness and efficiency of the company's products are not sold to the market" (the company). In addition, the utility model is also provided with the function of using the illuminance sensor to control light irradiation according to the external light intensity (ECO) button". In order to control the ambient brightness, the light exposure of the LED ceiling lamp can be automatically adjusted in the range of 0 to 100%.

Price is open. The market is expected to price, for 14, with tatami room color products for about 85 thousand yen, with no color of the product is 70 thousand yen. For 10 tatami room products were 65 thousand yen and 50 thousand yen, for 8 tatami room products were about 55 thousand yen and 40 thousand yen.

The discharge length extended to about 1.2 times to improve the efficiency of

The comprehensive efficiency of all kinds of fluorescent lamps are very high, for 10 ~ 14 tatami room products for 127.7lm/W, for 8 to 12 tatami rooms were 118.8lm/W, for 6 to 10 tatami rooms were 119.0lm/W. In order to improve the efficiency, a new fluorescent lamp. The length of the fluorescent lamp is extended to about 1.2 times compared with the original. In general, the fluorescent lamp to improve the luminous efficiency by extending the discharge length. From the ceiling lamp fluorescent lamp fluorescence can be seen, for 10 ~ 14 to 4 tatami room lamp re arranged in concentric circles, for 8 ~ 12 and 6 ~ 10 to 3 tatami room lamp re arranged in concentric circles. The concentric circular lamp tube is composed of a fluorescent lamp. For 10 ~ 14 tatami room products, the fluorescent lamp straight after the length of up to 3680mm. In addition, for 6 ~ 10 tatami rooms than other varieties of fine products using a circle of fluorescent lamp.

The 21 thousand - hour - long life of the fluorescent ceiling lamp is achieved by improving the holding capacity by the use of a coil (the three coil) of the re - holding emitter (which is an electron emitting material) of the. In addition, the fluorescent ceiling lamp is equipped with two white LED as "LED auxiliary light". LED auxiliary lamp is used as a safety lamp when the power cut and power failure can also provide minimum brightness. Fluorescent ceiling lamp equipped with Ni MH rechargeable battery. Even if there is no power from the commercial power supply, the battery can also be continuous lighting for about 5 hours. Prepared a total of 8 products, including whether or not equipped with LED ceiling lamp with "eco" button function of the product and whether with LED auxiliary lamp products, etc..

Price is open. The market is expected to price, for 10 ~ 14 tatami room products for around 37 thousand yen to 51 thousand yen (because of the function varies with the price for 8 ~ 12), tatami room products for 24 thousand yen left
