Description

LED lighting fixtures {LED Lighting}

The present invention relates to an LED lighting device using a light emitting diode (LED) as a light source, and more particularly, a printed circuit board formed in a modular form by fixing a plurality of LED chips to a frame constituting the lighting device. Easy installation, disassembly, and maintenance of the printed circuit board components can be easily detached from each other by a one-touch method. The present invention relates to an LED luminaire that is easy to install and maintain and to improve the quality of lighting.

In general, lighting fixtures are installed in a house, an office, a factory, and the like. Conventionally, an incandescent lamp or a fluorescent lamp is mainly used as a light source of a lighting fixture, and a fluorescent lamp is mainly used.

However, incandescent lamps and fluorescent lamps consume more power and have a shorter lifetime than lighting efficiency. Fluorescent lamps, in particular, have a serious problem of environmental pollution due to mercury that is emitted during disposal.

Due to these problems, in recent years, power consumption, semi-permanent life, and environmentally friendly LEDs have been spotlighted as light sources around the world.

In addition to the above advantages, LED has the advantage of easy adjustment of illuminance and color adjustment.

The present invention relates to an LED lighting device using the LED as a light source having many advantages as described above.

LED luminaires are similar in composition to general fluorescent lamps, as the light source is replaced with LEDs, and the power supply structure that supplies driving power to the LEDs is different. That is, the LED luminaire generally includes a frame having a receiving portion, an LED module (that is, a light source) embedded in the frame, a reflector for reflecting light incident from the LED to the front, and a cover covering the front of the frame. .

In addition, since LEDs have high brightness and strong straightness, the emitted light causes glare when the light is directly incident to the field of view, so that a cover is generally provided with a diffusion panel that prevents glare by illuminating the LED and illuminates a wide range. do.

In addition, even when mounting the frame of the luminaire to the ceiling, the conventional art generally uses the anchor work, there is also a problem that requires a separate processing process such as hole drilling for fastening the anchor bolt to the ceiling.

In addition, the lighting fixture is provided with a power supply for converting commercial power into a driving power supply to the light source (LED module).

However, commercial AC power is not a stable power source, and its strength fluctuates continuously, and this fluctuation is a fluctuation within the rated range, and most of the fluctuations do not have a significant adverse effect on the luminaire, but sometimes exceed the rated range in a short time. Overvoltages (e.g., 380V or higher) or instantaneous surge overvoltages (e.g., thousands of volts) may occur, and these overvoltages or surge overvoltages may have a fatal effect on power supplies or LEDs.

Therefore, it is necessary to protect the lighting fixture by cutting off such overvoltage or surge overvoltage, and many lighting fixtures have introduced a function of blocking the overvoltage.

However, in the prior art, the overvoltage blocking function is mostly embedded in the power supply, and there is a problem in that an interference phenomenon occurs between the overvoltage blocking circuit and the power supply circuit due to the built-in adjacent to each other.

In addition, in the case of a defective light emitting device or a bad power supply and overvoltage breaker after installation, it is difficult to maintain the component parts by disassembling and then disassembling each component part again.

In addition, in the LED lighting device, the printed circuit board is formed of a single unit, and the printed circuit board is fixed in contact with the housing (frame). For this reason, when any one of the light emitting diodes (LEDs) malfunctions, it is inconvenient to remove the entire printed circuit board from the housing in order to repair the malfunctioning light emitting elements or replace them with other light emitting elements. There was this.

Even when it is difficult to repair or replace a malfunctioning light emitting device, there is a problem that the entire printed circuit board has to be disposed of.

Since the frame and the fixed frame are made of a detachable structure, it is easy to separate the fixed frame and the frame to which the light emitting device is fixed. This has the advantage that the replacement can be made very easily when replacing the component after the installation of the luminaire.

The substrate to which the light emitting device coupled to the frame of the present invention is coupled, that is, the LED module in which a certain number of light emitting devices are fixed in a module type, is coupled to the heat sink coupled to the slide type, thereby improving workability and the parts in which the heat sinks are in contact with each other. The incision is configured so that the electric wire can be buried inside the frame and the LED modules can be installed in contact with each other, so there is no play between the LED module and the module. There is.

In addition, since the power is connected directly to the connector that is exposed at the top of the frame when the 220V power is connected, the power is easily connected and the power can be easily disconnected even when replacing the lighting fixture or the component. It is easy to separate.
