DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp type LED lighting apparatus using an LED (light emitting diode) which is directly attached to a fluorescent lamp fixture.

[0002]

2. Description of the Related Art Generally used fluorescent lamps have mercury vapor and an inert gas sealed in a cylindrical glass tube having a fluorescent material provided on an inner surface thereof, and electrodes provided on both inner ends thereof. The terminal to be connected is configured to protrude from both ends of the glass tube. This fluorescent lamp is fitted with a ballast that supplies an AC voltage necessary for starting the fluorescent lamp, and that supplies a current suitable for lighting, and a glow lamp that increases the starting voltage. To be installed.

In recent years, LEDs that consume less power, have excellent durability, and can emit various colors have been used in many fields, and lighting devices equipped with a large number of these LEDs have also been used.

Although a fluorescent lamp has a longer life than an incandescent lamp,
There is a drawback that the life is short and the power consumption is large compared to the LED. Further, since the fluorescent lamp is formed of a glass tube, it is vulnerable to impact and its color is limited to white. Lighting devices using LEDs are excellent in durability, but lighting equipment for mounting the LEDs and auxiliary equipment such as AC / DC converters, transformers, and control devices must be separately connected to the LEDs. In addition, the equipment cost was high and the construction work was troublesome.

Which converts the alternating current of the commercial power supply into direct current. Further, the AC / DC converter 7 is connected to a voltage controller 8, which adjusts the voltage supplied to each LED 9 to, for example, 2.8V. Further, a plurality of white light emitting LEDs 9 connected to the voltage controller 8 are arranged on the bottom surface of the support plate 3 as shown in FIG.

The fluorescent lamp type LED lighting apparatus 1 having the above-described structure is

Terminals attached to both ends of the fluorescent lamp type LED lighting device 1 are provided in the sockets 14 and 14. 4, 4 are fitted and attached in the same manner as the fluorescent tube.

When a switch (not shown) is turned on, the ballast 1
An AC current flows from the terminal 2 to the AC / DC converter 7 shown in FIG. 2 from the terminal 4 via the socket portion 14 and is converted into a DC current. The converted DC current is supplied to the voltage control unit 8
The voltage supplied to each LED 9 is adjusted to 2.8V. Here, the current whose voltage has been adjusted is supplied to the plurality of LEDs 9 arranged on the bottom surface of the support plate 3 to emit white light, thereby illuminating the room like a fluorescent lamp.

In this case, the fluorescent lamp apparatus 11 is provided with a ballast 12 for adjusting the voltage and a glow lamp 13, but is not provided with an electrode for generating and discharging a high voltage like a fluorescent tube. The glow lamp 13 has no effect. Since a high voltage at the start is not required, a constant alternating current is supplied from the ballast 12 to the AC / DC converter 7,
Further, since the voltage is adjusted by the voltage controller 8, there is no problem in lighting the LEDs 9.

Therefore, the length of the fluorescent lamp type LED lighting device 1 is set to a specified length according to the wattage (10 to 110 watts) of the fluorescent tube. It can be attached to the fluorescent light fixture 11.
In addition, since all the circuits required for lighting the LEDs 9 are housed inside the cylindrical pipe 2, there is no need to connect them separately, and installation and removal can be easily performed at home as well as the fluorescent tube.

The LEDs 9 are arranged on the bottom side of the support plate 3 and are directly irradiated with light rays, so that they can be illuminated more efficiently than a fluorescent tube in which the entire glass tube emits light. In addition, since the LEDs 9 are used, the lighting time is shorter than that of the fluorescent tube and the lamp is turned on instantaneously, and the power consumption is reduced by about 30% and the calorific value can be reduced by about 30% as compared with the fluorescent tube. . Furthermore, LED 9 has a lamp life of about 3 times that of a fluorescent tube.
Since it is longer than 0 times, and is strong against impact, and it is possible to use a plastic pipe instead of a glass tube, it is hard to be damaged by impact, and it is easy to replace parts, so repair is possible.
