By placing reflectors on the top and bottom of the LED bar, the light generated from the LED is reflected to the ceiling or wall without any loss, and there is no need for a separate building finish for indirect lighting, and it is small in size and convenient to install and dismantle. It is a ceiling indirect lighting device, characterized in that it is very easy to maintain and low power loss and can be used for a long time.

Description

Indirect lighting using LED bar {Indirect Lighting-Fixture which applies LED-bar}

The present invention relates to an indirect lighting device that creates a comfortable and warm atmosphere in the interior, and is installed on a ceiling or a wall of a residential building such as a commercial building or a high-end apartment or officetel where many people reside, such as a hotel or a department store, It is about a luminaire used for indirect lighting that softly illuminates the interior with this totally soft light.

Indirect lighting is indispensable in the interior ceilings of buildings that require colorful, beautiful and low-glare soft lighting, such as living rooms in residential buildings such as apartments and officetels, or in the lobby of department stores, hotels or large buildings.

Most indirect lighting uses a fluorescent lamp, and in order to install such an indirect lighting fixture, as shown in the cross-sectional view on the left side of FIG. Install the interior finishing material in the form of "L" to the bottom of the ceiling of the well, followed by the installation of lighting fixtures to install indirect lighting.

In the conventional method of indirect lighting, the ceiling and frame height of the building must be high because the dome-shaped ceiling or the well ceiling is required to install the lighting fixture, and the construction finish of the lighting fixture is very complicated. The installation cost is also high, and since the area where the lighting fixture is installed is so small that only a human hand enters it, it is very difficult to install and connect the lighting fixture and wiring, so that the construction period is long. In addition, even when maintenance is required, such as replacing the light bulbs of the lighting fixtures because you have to work by putting your hands only without seeing the eyes, there is a risk of electric shock, there is a disadvantage that easily exposed to the risk of fire due to electric leakage.

In addition, the indirect lighting method using fluorescent lamps requires a lot of money for maintenance due to shorter lamp life compared to the indirect lighting device using LEDs, and because there is no reflector around the lamp, a large amount of light is absorbed without going to the ceiling. Therefore, the light efficiency is very low, and the power efficiency is not good, so it consumes a lot of power, so the maintenance cost is high, and the initial installation cost of the interior to cover the fluorescent lamp is expensive, and the mercury is used to adversely affect the environment. There is this.

The present invention, in order to solve the various disadvantages of the indirect lighting using the conventional fluorescent lamps as described above, the manufacturing cost is low, installation is very fast and simple, safe and very easy to maintain, small power loss and small size I would like to propose a new method of indirect lighting that can be used for a long time.

In order to achieve the above object, the present invention uses a power-efficient LED bar as a light source, and by placing a reflecting plate on the top and bottom of the LED bar, while the light generated from the LED is reflected to the ceiling or wall without loss, It is an object of the present invention to provide a ceiling indirect lighting device, which is characterized by being compact and easy to install and dismantle.

As shown in FIG. 6, indirect lighting using a conventional fluorescent lamp requires space of at least 600 mm (width) x 200 mm (height) and complicated interior finish for bidirectional indirect lighting, but according to the present invention, 140 mm (width) x 70 mm ( It is easy to provide high quality illumination without expensive interior finish by installing only indirect lighting device of size), and because the parts used are very simple, the size of light fixture is small and light, so it is easy to install or maintain in buildings. It is very easy, safe and simple.

In addition, the use of high-efficiency LED as a light source consumes less power than fluorescent lamps, so it is very energy efficient, and there is no inconvenience to replace the lamp frequently due to its long service life. It is a three-color (RGB) LED module and dimmer The built-in controller provides an environment in which mood lights of various colors can be easily implemented.

In addition, the heat dissipation problem, which is the biggest disadvantage of LEDs, is configured to be quickly dissipated using a large LED bar frame that acts as a heat sink, thus creating the best environment in which LEDs are driven at a stable temperature. The high luminance, which is a disadvantage of the light, is configured to be widely dispersed while reflecting light from the upper and lower reflecting surfaces, so that the intense light of the LED is converted into a soft light with almost no glare, and thus is irradiated to the room.

Referring to the indirect lighting device according to the present invention in detail with reference to the accompanying drawings, as shown in detail in the cross-sectional view of Figures 1 and 2 and 3, 4, the fixture fixture frame 10 and the LED bar ( It is composed of three parts including the LED bar frame 20 and the luminaire lower cover 30 attached to the 21, LED bar frame 20 is attached to the frame using a fixing screw 11, The lower cover 30 is characterized in that the LED bar frame 20 is inserted into the groove formed in the longitudinal direction to be easily coupled.

Here, the LED bar frame 20 is provided with an LED bar installation part 23 to which the LED bar 21 is attached, and a light reflecting surface 22 is formed at the lower end of the LED bar frame 20, and the LED bar frame 20 is provided. It is made of a metal material such as aluminum to quickly dissipate heat generated from the LED bar 10 to maintain the LED to operate at a stable temperature. At this time, the light emitted from the LED bar 21 is reflected back to the upper reflecting surface 22 formed in the LED bar frame 20 and the lower reflecting surface 31 formed in the luminaire cover 30, so that the ceiling or wall without loss It is configured to be irradiated toward.

In addition, the lower cover 30 of the luminaire is produced by extrusion molding the synthetic resin material, the light reflecting surface 31 of the upper is coated with chrome or finished with a sheet of material having a high reflectance, the cover 30 The lower exposed portion 32) is characterized in that the finish is luxuriously coated or coated with a sheet or color in harmony with the interior around the lighting fixture.
