Description

Tubular LED lamp

[0001] The present invention relates to an LED lighting device, and more particularly, to an LED lighting device having a simple structure and easy to assemble and manufacture.

Fluorescent lamps are a typical lighting source for buildings. The fluorescent lamp is formed in a cylindrical shape so that it can be easily installed and replaced in an illumination device. The fluorescent lamp has advantages over an incandescent lamp because of its excellent energy efficiency and service life.

However, due to the emission of various harmful substances at the time of disposal, it adversely affects the environment. Also, it has lower energy efficiency than that of LED light, which has been recently developed and developed, and is gradually being replaced by an LED light.

The LED is a lighting technology using a semiconductor device, and has a low power consumption, a semi-permanent life span, a brightness controllability, and a low emission of carbon dioxide during manufacturing.

A number of techniques have been proposed for the illumination lamp using the LED. For example, in Korean Patent No. 997842, there is disclosed a lighting system including a main body of a lighting fixture provided with a ballast and connected to a power supply, an LED light-emitting plate installed in the main body of the lighting lamp, A plurality of illumination light dispersion grooves for dispersing LED light are formed on the inner side of the illumination light transmission shade. The LED light emission plate has a plurality of oblique light emission surfaces arranged to be inclined from the center to the edge in order to increase the dispersion angle of the LED illumination light And a power supply unit for switching the current supplied from the power supply to a square wave pulse from the microprocessor is installed in the main body of the illumination lamp. In consideration of the straightness of the LED illumination light of the LED illumination lamp, the LED illumination plates are inclined at different angles, Straightening is corrected and LED light The microprocessor switches the switching unit by switching the switching unit so that the current flowing through the LED is periodically switched. Thus, the LED illumination plate is periodically turned on, thereby reducing the accumulation of self-heating, It is possible to prevent deterioration due to overheating of each of the LED elements, thereby extending the lifetime of the LED illumination plate, leading to dispersion of the LED illumination light, and allowing the LED illumination light to be used comfortably without glare. .

In addition, EP-A-866586 has a body comprising a hemispherical base and an extension bent inwardly from both ends of the base; A heat radiating blade formed along the longitudinal direction inside the base of the main body and for increasing the radiating efficiency to increase the radiating efficiency; A plate mounted on an extension of the base, and a receiving protrusion connected to both sides of the plate; An LED module mounted between the receiving protrusions of the fixing portion and comprising a PCB substrate on which a plurality of LEDs are mounted; A cap which covers the main body and has a hemispherical shape and has a thickness at both sides relatively thinner than an upper center of the cap to increase a transmission amount of light radiated to both sides to expand a directivity angle of light emitted from the LED module; The cap has a lower end portion formed with a corresponding insertion portion to be coupled to the insertion portion, and the insertion portion and the corresponding insertion portion exhibit elasticity when the body and the cap are attached to and detached from each other, Detachment means for ensuring ease of engagement and disassembly of the body and the cap; And a stationary cover fixedly connecting both ends of the main body and the cap after being coupled with each other.

On the other hand, as described above, the LED has excellent characteristics such as long lifetime and high light conversion efficiency, but also has disadvantages such as high heat generation and nonuniform brightness depending on the direction.

The nonuniformity of the brightness is converted into a uniform brightness by using a diffusion plate or the like, but high heat generation is solved by a method of enhancing the heat radiation property of the illumination lamp itself.

Accordingly, in the general straight type LED lightings, the connection structure between the LED element and the illumination light is made by attaching a PCB including an LED element to the base of aluminum having a high heat dissipation property by using a conductive adhesive or the like, And the base quickly dissipates heat to the outside.

However, the structure of the above-mentioned illumination lamp requires a lot of work to manufacture, and it is somewhat inconvenient to replace the PCB.

Accordingly, there is a need for a new type of straight-type LED illumination lamp which is excellent in contact between the LED PCB and the aluminum heat sink, capable of quickly discharging heat, and also capable of easily connecting the LED PCB and the aluminum heat sink.

The straight tube LED illumination lamp according to the present invention provides a structure that can be combined with the PCB, the heat sink, the diffusion plate, and the outer cover only by inserting the PCB into the base plate in a slide form, In addition, since the members are coupled by the slide coupling, it is possible to combine various types of members, thereby providing a high degree of design freedom of the illumination lamp.

FIG. 1 is a perspective view of a base applied to an LED lamp of an intaglio type according to the present invention,
FIG. 2 is a cross-sectional view showing a state where various members are coupled to the base of FIG. 1;

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

First, FIG. 1 shows a cross section of a base 10 of an intaglio LED illumination lamp 100 according to the present invention.

The base 10 is made of a metal having a high thermal conductivity and plays a role of supporting the structure of the entire illumination lamp 100 and other members and is made of aluminum or a magnesium alloy or copper. Available.

As shown in FIG. 1, the base 10 has a symmetrical cross-sectional structure, so that only one configuration will be described.

The base 10 includes a flat plate 11 that is horizontal.

It is preferable that the flat plate 11 is formed in a planar shape with the same thickness and the surface is processed into a relatively uniform shape in order to improve the connectivity with other members.

Upper vertical portions 20 are protruded from left and right upper ends of the flat plate 11.

A top horizontal projection 21 is formed horizontally in the upper vertical portion 20 and a semicircular upper locking projection 22 is formed at an end of the upper vertical portion 20.

At this time, the upper horizontal protrusion 21 is oriented toward the inner side of the flat plate 11, and conversely, the upper locking projection 22 is directed toward the outer side of the flat plate 11.

A PCB board 40 including LEDs is coupled to the space between the upper horizontal protrusion 21 and the flat plate 11 as shown in FIG.

At this time, when the distance between the upper horizontal protrusion 21 and the flat plate 11 is formed to be equal to the thickness of the PCB board 40 and the PCB board 40 is inserted at a proper pressing force from the side, And the heat generated in the PCB board 40 is discharged through the flat plate 11 by the contact force between the back surface of the PCB 11 and the flat plate 11.

Here, the LED set is positioned on the upper surface of the PCB board 40 so that light is radiated toward the upper end of the flat plate 11.

When the distance between the upper horizontal protrusion 21 and the flat plate 11 is less than that of the PCB board 40 and the interference between the upper horizontal protrusion 21 and the flat plate 11 is difficult, a high contact force may be applied between the PCB board 40 and the flat plate 11 have.

2, a diffusion plate 60 for scattering light emitted from the LEDs is coupled between the upper latching protrusions 22 and the flat plate 11. As shown in FIG.

The diffuser plate 60 includes protrusions 61 at both ends and the protrusions 61 are located between the upper protrusions 22 and the upper vertical portion 20 so that they are fixed up and down and left and right.

The diffuser plate 60 may be configured in any form if the shape and position of the protrusions 61 are the same.

For example, a semicircular cross section as shown in Fig. 2, and an elliptical cross section or a rectangular cross section is also possible.

The lower end of the flat plate 11 is formed with a lower vertical portion 30 extending downward from the upper vertical portion 20.

The lower vertical portion 30 includes a lower inner horizontal projection 31 formed in the inner side of the flat plate 11.

A heat sink 50 having a plurality of fins formed on its surface is inserted and fixed between the lower inner horizontal projection 31 and the lower surface of the flat plate 11 as shown in FIG.

The gap between the lower inner horizontal projection 31 and the flat plate 11 may be equal to or less than the thickness of the heat radiating plate 50 to control the contact force between the heat radiating plate 50 and the lower plate 11.

The bottom vertical portion 30 includes a lower end locking protrusion 33 formed at an end of the flat plate 11.

When the lower vertical part 30 is formed to have the same length as that of the vertical part 20, the protruding part 71 formed in the outer cover 70 is formed in the space between the lower end locking protrusion 33 and the lower surface of the flat plate 11. [ ) Can be combined.

However, since the heat sink 50 has a high-height fin for heat dissipation efficiency, the lower vertical portion 30 includes a separate lower outer horizontal projection 32 for coupling the outer cover 70 .

Therefore, the protrusion 71 of the outer cover 70 is seated and engaged with the space between the lower outer horizontal protrusion 32 and the lower stopper protrusion 33.

The outer cover 70 is fixed to the left and right up and down directions by the lower outer lateral projection 32 and the lower end locking projection 33. [

In addition, when the shape and position of the protrusion 71 are constant, the outer cover 70 can have any other shape, so that it is possible to combine various outer covers 70.

As described above, the straight-tube LED illumination lamp 100 according to the present invention can be manufactured by simply inserting the PCB board 40, the heat sink 50, the diffusion plate 60, and the outer cover 70 on the side of the base 10 Since the assembly is completed, it has high manufacturing productivity.
