LED LAMP MODULE HAVE FUNCTION OF RADIATING HEAT AND LED LIGHTING APPARATUS WITH LED LAMP

The present invention relates to an LED lamp, and more particularly, it is possible to replace only the LED lamp, not the entire LED module, and to prevent the occurrence of failure by quickly discharging the heat generated from the inside to significantly improve the life of the product The present invention relates to an LED lamp module having a heat dissipation function and an LED lamp having an LED lamp module.

In general, LEDs are widely used as light emitting components such as lightings because of their long life, low power consumption and high output light.

In the context of conventional lighting, the LEDs have completely different characteristics in certain problems. The LEDs are small and emit less heat than conventional lighting, but because of their small size and low heat resistance, it is necessary to ensure that the temperature of the LEDs does not rise to excessively high values. In addition, it is important that the energy supply to the LEDs is well regulated, and polarity is an important factor along with the voltage. If the polarity is wrong, the LED will not work at all, and too high a voltage or current will greatly reduce its lifetime.

LED lighting devices currently on the market are equipped with a transformer for supplying low voltage power suitable for the LED, and the LEDs are fixedly installed to be connected to a terminal for outputting a specific voltage.

However, this has several disadvantages. LEDs are manufactured with different specifications at output and color temperature. If the user purchased a particular LED lighting device, the amount of light is very unlikely to rise to the expected level. Not only can there be much more light than expected, but there can be less. It is also possible that the type of light does not meet expectations. The light may be too white or too soft. In addition, since the LEDs are fixedly installed in the LED lighting device, the LEDs can be replaced only by an expert or the entire LED lighting device must be replaced. This is undesirable for the user. In addition, the supplier of the LED lighting apparatus must manufacture and store the LED lighting apparatuses having different LEDs.

German utility model DE 299 15140 U1 describes an LED lamp which can be screwed or assembled, where the lamp may or may not be equipped with electronic components to supply energy to the LED lamp. The LED lamps according to DE 299 15 140 U1 are replaceable and may also be suitable for use in LED lighting units with transformers and possibly rectifiers.

However, in the LED lamp disclosed in the German utility model DE 299 15 140 U1, since the light is performed after the LED lamp is inserted and coupled to the external socket, the internal heat is not discharged to the outside, and thus the LED is easily overheated.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in more detail the present invention.

1 is an exploded perspective view of the LED lamp module 100 according to an embodiment of the present invention, Figure 2 is an exploded cross-sectional view of the LED lamp module 100 of FIG.

As shown in FIG. 1 and FIG. 2, the LED lamp module 100 includes an LED lamp 1 and a fitting module 2.

1 and 2, the LED lamp 1 includes an LED 3, a holder 4, and a cap 5.

The LED lamp 1 of the above configuration does not have a transformer and may include one or more of an LED drive driver or a capacitor for controlling current, and through which a power supply prepared for direct connection with the LED 3 is made. It is necessary. The LED 3 is to be formed in a sphere covered with a light-transmissive sealing member in Figures 1 and 2, the shape may have a variety of shapes as necessary.

As a result, the LED 3 has a pair of electrical connection parts 6 formed at the lower end of the conductive material.

The holder 4 is formed of a cylindrical thermal conductive material, a space is formed at the center thereof so that at least one of the LED driving driver D or the capacitor C can be positioned, and a lower portion of the holder 4 is electrically connected to the electrical connection 6. A pair of legs 7 made of a conductive metal material to be connected protrude downward from the bottom surface, and a holder male screw portion 4A in which the cap 5 is screwed is formed on the outer periphery of the upper end portion. One or more of the LED driving driver D or the capacitor C may be installed. In general, the life of the LED lamp is determined by the life of the capacitor. That is, when the life of the capacitor for driving the LED lamp runs out, it is necessary to replace the LED lamp. Accordingly, the present invention assists the capacitor provided in the power supply device for supplying power to the LED lamp 1 by mounting the auxiliary capacitor C in the inner space of the holder 4 to extend the life of the capacitor. By extending the life of the LED lamp (100).

 The fitting module 2 includes a fitting sleeve 21, a fitting 22, and a fitting housing 23.

The fitting sleeve 21 has an inner diameter corresponding to the outer diameter of the holder 4, and the outer diameter is manufactured in a cylindrical shape corresponding to the fitting housing 23. On the outer circumferential surface of the holder 4 is formed a heat radiating rib 30 radially along the circumference of the heat radiating groove 30A is formed in the longitudinal direction to a predetermined depth radially. Lower ends of the heat dissipation ribs 30 are screwed to form a fitting sleeve male threaded portion 21A. The fitting sleeve 21 of the above configuration may be made of aluminum, copper, copper alloy, or the like having high thermal conductivity.

The LED lamp 1 and the fitting sleeve 21 can be easily detached from each other, and the outer diameter of the LED lamp 1 can be discharged to the outside by the contact with the atmosphere. It is formed to be smaller than the inner diameter. As a result, when the LED lamp 1 is inserted into the fitting sleeve 21, an air gap G for heat dissipation is formed. The air gap G releases the heat of the LED lamp 1 to the outside more quickly by bringing the outer surface of the holder 4 into contact with the air, thereby preventing the LED lamp 1 from being deteriorated by heat generation. . The spacing of the air gap G is preferably about 0.1 mm or more for smooth heat dissipation and easy replacement of the LED lamp 1.

The fitting 22 is manufactured to have a cylindrical shape with an empty inside, and a pair of contacts (electrode terminals) 24 in which the legs 7 are in electrical contact with each other is provided to face each other. And the upper surface is formed in a pair of fitting openings 25 of the arc shape. The fitting opening 25 is formed so that one end of the arc shape has a diameter into which the leg 7 can be inserted, and the other area has a width smaller than the diameter of the leg.

Outside the fitting 22, electrode terminal holes 22B are formed at positions corresponding to the ends of the contacts 24, respectively, so that the external power lines can be connected to the contacts 24. As shown in FIG. Both side surfaces of the fitting 22 are formed with a fixing groove 22H inserted into the center direction at a predetermined depth in a position facing each other. Fitting 22 having the above-described structure may be made of an insulating material of ceramic or reinforced plastic.

The fitting housing 23 has an open upper portion and a lower shielded cylindrical shape, and a fitting housing female screw portion 23A is formed at the upper end of the inner wall along the circumference. The bottom surface of the fitting housing 23 is formed with a fitting housing opening 31 for fixing the fitting housing or drawing in an external power line, and having at least one protruding therein to be inserted into the fixing groove 22H from the shielded bottom. The positioning rod 23B protrudes. The fitting housing may be formed of a metal material such as aluminum having high thermal conductivity, and may be configured to further improve heat radiation efficiency by directly receiving heat generated from the fitting 22 and dissipating it to the outside.

3 is a perspective view of an assembled state of the LED lamp module 100 of Figures 1 and 2, Figure 4 is a cross-sectional view of the LED lamp module 100 of FIG.

The LED lamp module 100 having the configuration shown in FIGS. 1 and 2 is assembled as shown in FIGS. 3 and 4.

3 and 4, in order to assemble the LED lamp module 100, the electrical connection part 6 of the LED 3 is inserted into the holder 4 to be connected to the LED driving driver, and the LED driving driver D Connect the power input terminal to the leg (7) and mount it to the holder (4), and then screw the cap (5) to the holder male screw portion (4A) formed on the upper portion of the holder (4) to attach the LED (3) to the holder (4) ). By such a combination, the LED lamp 1 is assembled.

The fitting 22 is mounted in the fitting housing 23 by allowing the position fixing rod 23B of the fitting housing 23 to be inserted into the fixing groove 22H. The fitting 22 is coupled to the fitting housing 23 so as not to disturb the wiring of the electric wire by inserting the position fixing rod 23B into the fixing groove 22H.

After the fitting 22 is coupled to the fitting housing 23, the leg 7 of the LED lamp 1 is inserted into the fitting opening 25 of the fitting 22, and then rotated to engage the fitting 22. At this time, the leg 7 is electrically connected to the contact 24 inside the fitting 22, so that the lower end of the wide diameter of the leg 7 is not separated from the fitting housing opening 31 at the inner surface of the fitting 22. Supported and maintained in the fitting 22. This coupling is called GU bayonet coupling, which is a common connection in the lighting industry between lamps and fitting modules.

The combination of the fitting 22 and the LED lamp 1 is not limited to the GU bayonet coupling, but the combination of the LED lamp 1 and the fitting 22 is an LED lamp and a fitting module such as an Edison screw or a BA bayonet coupling. It will be clear that the LED lamp modules can be coupled in a similar manner through different couplings between them.

After the fitting sleeve 21 is inserted into the LED lamp 1, the fitting sleeve male threaded portion 21A formed at the lower end of the fitting sleeve 21 and the fitting housing female threaded portion 23A of the fitting housing 23 are screwed together. By doing so, the assembly of the LED lamp module 100 is completed. The process of coupling the fitting sleeve 21 to the fitting housing 23 may be performed regardless of the fixing of the LED lamp 1 to the fitting 22.

During the assembly process of the LED lamp module 100 described above, the lower end portion of the heat dissipation groove 30A formed on the outer surface of the fitting sleeve 21 is spaced apart from the surface of the fitting housing female screw portion 23A by a predetermined distance, thereby providing a plurality of heat dissipation holes 40. ) Is formed. Therefore, the heat generated inside the LED lamp module 100 is discharged to the outside by the heat conduction of the fitting housing 23 and the fitting sleeve 21 as well as heat is discharged to the outside through the heat dissipation hole 40. Therefore, the heat radiation efficiency is significantly improved.

In addition, the LED lamp 1 in the assembly of the LED lamp module 100 is completed, the leg 7 is maintained in a fixed state by the GU bayonet coupling to the fitting 22. In addition, the LED lamp 1 can be freely moved up and down inside the fitting sleeve 21 and the fitting sleeve 21 only supports the LED lamp 1 in the horizontal direction. Therefore, since the LED lamp 1 in the LED lamp module 100 of the above-described structure can be freely separated from the LED lamp module 100 by releasing the GU bayonet coupling, the consumer does not have to remove the fitting sleeve 21. The broken LED lamp 1 can be replaced easily.

The LED lamp module 100 having the above-described structure has an interfacial surface where electrical contact is performed, such as between the electrical connection part 6 and the inner wall of the through hole 4B, and between the leg 7 and the inner wall of the through hole 4B. It may be configured to be insulated with this insulator.

When the fitting module 2 according to the present invention is mounted on the LED lamp module, the user can select the LED lamp having the LED having the desired brightness and color, and replace the LED lamp in a very simple manner. The user can easily configure the lighting having the color and the color, so that the brightness and color of the light do not depend on the choice of the supplier of the LED lighting device.

In addition, the LED lamp module 100 of the present invention can be produced by a variety of lighting. 5 to 7 show a downlight LED lighting 200 and the ceiling LED lighting 300 of the lighting.

FIG. 5 is a partial cross-sectional view of the downlight LED lamp 200 to which the LED lamp module 100 of FIGS. 1 to 4 is applied.

The downlight LED lamp 200 of FIG. 5 has a shape that corresponds to the shape of the luminaire case 220 in the interior of the luminaire case 220 and the luminaire case 220 of a circular or polygonal horn-shaped upper portion and an upper portion thereof.

It is configured to include an LED lamp module 100 is fixedly coupled to electrically connected to the power supply unit 230.

The downlight LED lamp 200 may also be formed with one or more mounting holes 212 so that one or more LED lamp module 100 may be mounted.

The down light LED lamp 200 of FIG. 5 also extends its life due to the heat dissipation function of the LED lamp module 100. When the LED lamp 1 is damaged, only the corresponding LED lamp 1 needs to be replaced, thereby maintaining the maintenance cost. It has the advantages of low cost and easy management.

As shown in FIG. 12, the second LED lamp module 100A of FIGS. 8 to 11 may be applied to the downlight lamp to form the second downlight lamp 200B of FIG. 12.

In addition, as shown in FIG. 13, the second LED lamp module 100A of FIGS. 8 to 11 is applied to the ceiling LED lamp to form the second ceiling LED lamp 300A of FIG. 13.

14 is a perspective view of the LED lamp to which the cap is applied to the lampshade reflector 5a as a modified embodiment of the present invention, Figure 15 is a perspective view of the LED lamp module to which the LED lamp of Figure 14 is applied.

As shown in FIGS. 14 and 15, the cap 5 of the LED lamp modules 100 and 100A directly receives heat generated from the LED 3 and the holder 4 fixing the LED 3 to the outside. It may further comprise a lamp reflector (5a) is made of a metal material having a high thermal conductivity, such as aluminum material so as to emit.

The LED lamp module 100, 100A and the lamps 200, 200A, 200B, 300, 300A of the present invention described above achieve the special advantages and the optimal life of the LED lights. A replaceable LED lamp 1 with a suitable assembly is useful and can be connected to a suitable LED lamp electrical source, such as a low voltage supply of direct current for the required voltage or current, and due to good heat conduction from a position remote from the LED The LED can be operated under optimum conditions of the amount of light and the lifetime obtained.

In connection with other light sources, the LED uses a small output and the ratio of this output to the heat is also small, but the small surface area of the LED can quickly lead to high temperatures.

Therefore, the heat dissipation efficiency is remarkably improved by forming a heat dissipation hole capable of dissipating the heat inside and a good heat conduction characteristic of transferring heat away from the LED to the outer surface of the holder. This allows the LED to operate at lower operating temperatures, which greatly increases its lifetime.

In a preferred embodiment, the holder consists mainly of thick walls, which have a positive effect on thermal performance and heat transport, and are usually made of a material having good thermal conduction performance, such as aluminum. Aluminum is also a good electrical conductor and care must be taken to ensure good electrical insulation between the holders and the conductors for supplying the terminals and the LEDs.

In another useful embodiment of the LED lamp module according to the invention, electronic components, which are not shown in the figures but are electrically connected to the electrical wiring for supply to the LEDs, can be received in the recesses of the body part of the holder. . If these electronic components include dimmer circuits connected to a temperature sensor, the lamp system can be operated with maximum light output and cooling performance in terms of maximum power and size.

When the temperature exceeds the threshold, the dimmer circuit dims the LEDs, reducing the heat generated. In addition to the temperature sensor and the dimmer circuit, a control circuit for controlling the dimmer may be provided if the signal of the temperature sensor exceeds a threshold. If the electronic components include a circuit for switching the voltage polarity, it is no longer necessary to arrange the supply voltage with the right polarity to be provided to the LEDs, since this circuit then corrects the wrong polarity possible in the voltage supply. to be.

Again in a more effective embodiment of the LED lamp module according to the invention, in mutual mounting, the holder and the fitting module are configured to include at least mating mutually contacting surfaces as surface components.

Heat transfer from the holder to the fitting module is transferred by air gaps present between each other. Cooling of the LEDs increases as the air gap is as narrow as possible and the area is large. The gap and area of the air gap are designed in consideration of the general mechanical processing accuracy, the maximum thermal energy to be transmitted, and the management target temperature of the holder. The heat transfer between them will therefore increase with increasing temperature. In addition, by forming the heat dissipation groove 30A, the outer surface area of the holder is further increased to increase heat transfer from the holder to the fitting module, and the heat dissipation hole 40 when the fitting sleeve 21 and the fitting housing 23 are combined. Since the heat generated from the LED lamp module 100 is more quickly discharged to the outside by forming the LED, cooling of the LEDs is further promoted.

 In a preferred embodiment the fitting module mainly comprises a fitting housing with a cylindrical outer shape, the cylinder diameter being in the range 26-28 mm or in the range 38-40 mm or in the range 50-54 mm, the mounting of the holder at the end The fitting housing facing away from the position is provided with a fitting opening with an internal screw and M10x1. These sizes are close to the typical sizes of the fitting modules and are effective when the LED lamp module according to the invention is intended to be mounted on a general lamp socket when the external dimensions of the fitting modules are consistent with the standard size of the lighting industry. Fitting openings with internal screws M1Ox1 are also common in the lighting industry.

In a very preferred embodiment of the present invention, the fitting module and the holder are implemented by a known system such as Edison screw for mutual mounting, and the outer diameter of the holder at the Edison screw position and the inner diameter of the fitting module differ by more than 1 mm from 14 mm, 27 mm or 40 mm. Has Thus, the fitting module according to the present invention can accommodate other lamps having an Edison screw, and the LED lamp according to the present invention can be fixed to another fitting module in addition to the fitting module according to the present invention. Another preferred possibility for the mutual mounting of the fitting module and the holder is by means of a bayonet system in the form of a BA or GU. Both forms are known in the lighting industry.
