Description

Integrated body LED fluorescent light fixture {One body type LED light apparatus}

The present invention relates to an integrated LED fluorescent light fixture, and more particularly, the LED substrate, the heat sink and the frame attached to the LED element is integrally formed, easy to install and detach in a building, has a robustness and robustness, almost failure The present invention relates to an integrated LED fluorescent light fixture having a longer life than conventional fluorescent lamps using LED elements.

Conventional fluorescent lamps are the most commonly used light sources in the surroundings, and these fluorescent lamps are composed of fluorescent lamps and ballasts. Fluorescent lamps are tubes sealed with fluorescent material and argon gas and mercury vapor in them. When the electricity is supplied, the lighting tube becomes hot due to the electricity. In addition, since the tube current gradually increases when the discharge starts, the tube destroys the electrode, so that a ballast such as a choke coil is used to limit the current to a certain value or less.

Most commonly used luminaires use fluorescent lamps, and these conventional fluorescent lamps are driven at a frequency of 60 Hz. Therefore, the user may feel tired eyes when using the lamp for a long time due to flickering 60 times per second. Feeling a lot, due to the self-heating increases the ambient temperature causes high power loss, there was a disadvantage that the fluorescent lamp is easily broken when overheated. As a result, a conventional lighting fixture such as a fluorescent lamp has a problem that the service life is shortened due to the temperature rise and the high power loss, and the replacement parts are expensive because there are many parts used.

On the other hand, LED (Light Emitting Diode) has a feature that is not only small and long life compared to the conventional light source, but also because the electric energy is directly converted into light energy, less power is consumed and excellent energy efficiency. Therefore, various lighting fixtures using such an LED as a light source have been developed. Recently, a fluorescent lamp-type lighting fixture that can replace a conventional fluorescent lamp has been disclosed.

However, these LEDs generate a lot of heat due to the high current and high brightness chips of the light emitting diodes, and have a problem in that the optical characteristics are degraded at high temperatures.

Therefore, in order to maintain a constant optical characteristics, the heat generated from the LED must be sufficiently radiated, and if the radiated heat is insufficient, the optical output characteristics may be degraded, or the long-term lifetime and efficiency may be reduced. It is necessary to release the internal heat of the.

It is an object of the present invention that the LED substrate, the heat sink and the frame with the LED element is integrally formed so that there are few parts used, and it is easy to install and detach in a building without complicated assembly process, even if the life of the LED element is short, the LED substrate To provide an integrated LED fluorescent light fixture with robustness and robustness that can be replaced.

The integrated LED fluorescent light fixture of the present invention for achieving the above object is a fluorescent type LED lighting fixture, the heat sink is formed in the upper portion, the lower body is mounted to the LED substrate with the LED element attached to the bottom; A translucent plastic diffusion cover provided on the lower portion of the LED substrate and coupled to the main body frame to diffuse light emitted from the LED device; And side caps that are bolted to and coupled to both ends of the body frame.

In addition, the integrated LED fluorescent light fixture of the present invention, a fluorescent LED light fixture, the center frame having grooves on both sides; A main body frame having a heat dissipation plate formed at an upper portion thereof, an LED substrate having an LED element attached thereto at a lower portion thereof, and an oblique downwardly bent at both ends of the heat dissipation plate having a protruding portion coupled to the center frame at one end thereof; A translucent plastic diffusion cover provided below the LED substrate and fitted to the main body frame to diffuse light emitted from the LED device; And side frames coupled to both ends of the center frame and the main body frame, and protrusions of the main body frame are slidably coupled to both side grooves of the center frame, respectively.

Here, the heat sink is a plurality of heat radiation fins are formed in the longitudinal direction.

In addition, the LED substrate is attached to the body frame using an insulating tape.

In addition, the diffusion cover is made of a semi-cylindrical shape.

According to the integrated LED fluorescent lamp luminaire according to the present invention, since the LED substrate, the heat sink and the frame with the LED element is integrally formed, the parts used are not easily broken, and the assembly is easy, and the desired position There is an advantage that it is easy to install and detach.

In addition, since the heat radiation fin is formed on the upper portion of the LED substrate, the heat generated from the LED element through the heat radiation fin is effectively dissipated to the outside has the advantage that it can further improve the durability of the LED fluorescent lamp.

In addition, since the mounting and detachment of the LED substrate is simple, the life of the LED element is over, and when the LED substrate is replaced, the LED substrate can be easily replaced without removing the entire lighting fixture.

In addition, since the integrated fluorescent lamp has a simple appearance and is effective for interiors, there is an advantage of improving the beauty of the interior of the building.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the integrated LED fluorescent light fixture of the present invention is first formed a main body frame 20, the lower portion of the main body frame 20, the diffusion cover is fitted and coupled to the main body frame 20 23 is positioned, and the side cap 40 is covered and fixed to both sides of the body frame 20 and the diffusion cover 23 coupled.

At this time, the heat sink 25 is formed on the upper portion of the main body frame 20, the heat sink 25 is provided with a plurality of heat radiation fins 21 are formed in the longitudinal direction of the LED element that generates a lot of heat itself It serves to dissipate heat generated from the outside, and in particular, the surface area in contact with the air is maximized due to the heat radiation fin 21 to further enhance the heat radiation effect of the heat sink.

2 and 3, a through hole 24 is formed between the LED substrate 22 and the heat sink 25, and heat generated from the LED substrate 22 due to the through hole 24 is formed. It radiates more efficiently.
