Hitachi Lighting released the Hf86 fluorescent lamp "HI-POWER UV" (FHF86) and the lighting fixture "Hf86 HI-POWER" using the fluorescent lamp. The product is capable of achieving the same brightness with approximately half the power of a 400W mercury lamp. The product is intended for use in factories, warehouses, etc., and is used to provide lighting fixtures on ceilings that are 5 to 10 m high from the floor. In this application, the 400W mercury lamp has been used before, and the goal of the new product is to replace the mercury lamp.
The Hf86 fluorescent lamp is a high-frequency illumination fluorescent lamp with a length of about 2.5 m, and the luminous efficiency is as high as about 110 lm/W. By changing the control circuit of the fluorescent lamp appliance, the output power was increased and the brightness was increased to 1.2 times that of the original product. When using a double-tube fluorescent lamp, the same brightness of 2,400 lm as the 400W mercury lamp can be achieved, thus replacing the mercury lamp. The power consumption is equivalent to about half of the mercury lamp, only 208W. Moreover, it takes less time to illuminate than a mercury lamp. It takes 20 to 30 minutes for the mercury lamp to illuminate to fully illuminate, so there is a disadvantage that the lamp cannot be turned off during a lunch break or the like. However, fluorescent lamps are different. It takes almost no time before they are fully lit, and can be turned off at any time when not in use, so it is expected to achieve energy-saving effects.
Fluorescent lamps produce a problem that the life of the fluorescent lamp is shortened when the output power is increased and the brightness is increased. This time, the fluorescent lamps and fluorescent lamps were improved respectively, thereby extending the life of the fluorescent lamps to 1.3 times that of the original product and achieving 15,000 hours. Compared with the 400W mercury lamp, the life is 3,000 hours.
There are two main reasons for the shortened life of fluorescent lamps when increasing the output power of fluorescent lamps. One is the filament life. With regard to this problem, if it is possible to prevent the filament from being excessively scattered by the electron-emitting material and slowing down the rate of the emitted electrons, the life of the filament can be prolonged. To achieve this goal, it is necessary to keep the temperature of the part of the radioactive material, the bright spot, at a constant level. The other is that the fluorescent tube is blackened to cause a decrease in brightness. The reason is that the electron emission material of the filament is scattered, the mercury in the fluorescent tube is combined with the sodium in the glass, and the ultraviolet light contained in the fluorescent lamp causes the glass to undergo color change. These problems are solved by coating the phosphor between the glass and the glass to prevent the combination of mercury and sodium and to shield the ultraviolet rays.
In order to keep the filament glow temperature at a constant level, a filament current control circuit is provided on the lighting fixture this time. Generally, when a fluorescent lamp is turned on, first, a current is input to the filament to start, and the filament emits electrons. Then, after lighting, in order to emit electrons, a filament current flows and the emitted electrons move toward the anode. The problem at this time is that the preheating at the time of starting is insufficient, and the electron emitting substance is consumed. Further, there is a problem in that the lamp current is increased after the output power is increased, and the flash point temperature is increased accordingly. Therefore, the lighting fixture of this time reduces the phenomenon of insufficient preheating by increasing the current flowing through the filament at the time of starting. In the case where the lamp current is increased while lighting, the flash point temperature is maintained by reducing the filament current.
In terms of fluorescent lamps, like the “Flaming UV†series of household fluorescent lamps released by Hitachi Lighting in August 2007, the filament life and the blackening of the fluorescent tubes are prevented by improving the filament and the ultraviolet shielding material.
If the fluorescent lamp Hf86 HI-POWER released this time is used in combination with the original Hf86 type fluorescent lamp, although the brightness will increase, the life of the fluorescent lamp will become shorter. When the fluorescent lamp HI-POWER UV is used in combination with the original Hf86 type fluorescent lamp, the life is prolonged but the output power is not improved.
Will become the key to energy saving for small and medium-sized buildings and factories
From the perspective of electricity consumption in Japan, the electricity consumption of small and medium-sized buildings and factories will increase to twice the current level in the past 30 years. Among them, in the power consumption of buildings, lighting accounts for a fairly high proportion. Under this background, large-scale stores with a floor space of 2,000 to 3,000 pings, such as home building materials stores and home appliance stores, have begun to adopt Hf86-type fluorescent lamps on the premise of achieving energy-saving effects. The market size of Hf86 fluorescent lamps was 70,000 in 2002, and in 2006 it surged to 490,000 in 7 times that of 2002. Hitachi Lighting hopes to market fluorescent lamps and fluorescent lamps that can replace mercury lamps and halve the power consumption, meeting the energy-saving needs of the commercial field. The company's goal is to expand the market for fluorescent lamps to factories and warehouses in addition to buildings and stores by capturing this demand.
