Description

[0001] RAD PLATION LIGHTING [0001]

The present invention relates to an LED PL that improves the heat dissipation effect, more specifically, by providing the LED module with a diffusion cover by inserting the LED bar in the housing, one side of the heat sink constituting the LED bar is placed on the atmosphere So that the heat radiation effect can be enhanced.

Generally, in order to emit light from a semiconductor such as an LED, energy is supplied to the semiconductor and then light is generated. In this case, depending on the method of supplying energy to the semiconductor, there are three types of light emitting devices: PL (Photo Luminescence), CL (Cathode Luminescence) It is divided.

EL is a method of injecting electrons to make a transition, that is, a method of making positive (+) and negative (-) electrodes, It generates light. The resulting light is a spectrometer called a monochromator, which extracts the wavelength of the semiconductor and measures the wavelength position and the intensity of the wavelength.

On the other hand, in the patent literature, such a LED PL type luminaire is disclosed. The patent literature relates to a PL (Photo Luminescence Lamp) fixedly mounted on a ceiling, in which an LED is used as a light source, external air of a PL lamp is introduced into the lamp, heat exchange is performed with the LED module and the inverter, And an air circulation cooling type LED PL lamp for cooling the heat generated in the LED by being discharged outside the PL lamp by air circulation.

However, such LED PL luminaires have the following problems.

(1) Generally, since the LED module is composed of a plurality of LED elements, a heat sink is used so that heat generated from these elements can be efficiently emitted.

(2) At this time, the heat radiating plate (or the LED module) is mounted in a space formed by the housing and the diffusion cover, and the heat radiating function is performed through the heat radiating hole formed in the bottom surface of the housing.

(3) The greater the number of heat dissipation holes formed on the bottom surface of the housing, the higher the heat dissipation effect.

(4) However, there are limitations in forming as many heat dissipation holes as possible on the limited floor surface due to the space between the heat dissipation holes and the heat dissipation holes.

(5) The limit of forming the heat dissipation holes serves as a limiting factor for discharging the heat generated from the LED module to the outside of the housing, thereby degrading the heat dissipation effect.

(6) On the other hand, as another method for increasing the heat radiation effect, the LED module may be mounted on the housing so that the heat sink is in contact with the heat dissipation hole.

(7) However, even in this case, there is a problem that heat radiation is not performed smoothly in the heat radiation plate portion contacting the fissure on the heat dissipation hole and the heat dissipation hole, because the heat dissipation action is performed by the area of the heat dissipation plate in contact with the heat dissipation hole.

Korean Patent No. 1280982 (registered on June 26, 2013)

The present invention has been devised in consideration of this point. The LED module is inserted into the insertion hole by inserting an LED hole into the inside of the housing, And it is an object of the present invention to provide an LED PL lamp which improves the heat dissipation effect by making it possible to expose the entire one surface to the atmosphere while preventing the heat sink to come into contact with the housing, thereby improving the heat radiation effect of the heat sink.

Particularly, in the present invention, the shape of the insertion hole is formed into a polygonal shape having various shapes such as a circle, an ellipse, or a triangle and a quadrangle, so that a heat dissipation effect LED PL light fixtures with improved LED lighting.

In order to achieve the above object, the LED PL lamp having improved heat dissipation effect according to the present invention has a long container shape, and has a plurality of cut surfaces 110 ), An insertion hole 120 formed in a predetermined matrix form on the bottom surface, an inverter 130 installed to protrude downward from the bottom surface to supply external power, an insertion hole 120 formed in a matrix shape, A housing 100 having a plurality of resilient locking pieces 140 protruding from the bottom surface at predetermined intervals so as to be positioned on the side of the rim and a retaining ring 150 protruding upward from a middle portion of the bottom surface; The LED module 220 is disposed at a position corresponding to the insertion hole 120 and is attached to the bottom surface of the housing 100 so as to be caught by the elastic catching piece 140 Two LED bars 200 fixed on the left and right sides of the inverter 130 so that each of the LED modules 220 can be irradiated to the outside of the housing 100 through the insertion hole 120; Two diffusion covers (300) covering the lower portion of the housing (100) so as to be positioned on both sides of the inverter (130); And a guide 410 formed on a surface of the housing 100 opposite to the housing 100 so as to be slidable, And a mounting bracket (400) having a latching protrusion (420) which is caught by the latching ring (150) as the latching protrusion (420) is hooked.

In particular, the insertion hole 120 is formed in a circular, elliptical, and polygonal shape.

According to the LED PL lamp which improves the heat dissipation effect of the present invention, it has the following effects.

(1) Since one side of the heat sink formed on the LED bar is exposed to the atmosphere through the inside of the housing, it is possible to increase the heat radiation effect by eliminating the area contacting with the housing.

(2) In particular, the heat dissipation efficiency of the heat dissipation plate is proportional to the surface area of the heat dissipation plate. Since one side of the heat dissipation plate is exposed to the air, the heat dissipation effect can be improved through the air having high heat dissipation efficiency.

(3) In addition, since the LED bar is installed so that heat can be radiated directly through one side of the heat sink and the air, the present invention can be easily mounted and easily assembled to improve productivity.

(4) Since the heat sink is not exposed to the outside of the housing, the appearance of the luminaire can be improved.

(5) In particular, if the heat sink is exposed to the outside of the housing, a separate process or finishing process or a process for ensuring aesthetics is required for the aesthetic appearance of the heat sink. However, since the heat sink is located in the housing in this case, The luminaire can be assembled and used without any process.

(6) It can be easily assembled and disassembled by pushing the housing against the mounting bracket, so maintenance such as construction and replacement of the luminaire can be made easy.
