Description

LED lamp module including heat dissipation function and LED lighting equipment including LED lamp module

technical field

The present invention relates to LED lamps and, more particularly, to LED lamp modules in which not the entire LED module, but only the LED lamp can be replaced and prevent failure by quickly removing internally generated heat to significantly extend product life. The heat dissipation function is included, and relates to an LED lighting device including the LED lamp module.

Background technique

Generally, LEDs are widely used as one of light emitting elements of light emitting devices due to their long service life, low energy consumption and high output light.

LEDs are of a different nature on specific issues than traditional luminaires. Compared with ordinary lamps, LEDs are smaller in size and lower in heat dissipation, but the temperature of LEDs must not be too high because of their small size and low heat resistance. In addition, the energy delivered to the LED needs to be well controlled, and important factors for LEDs include voltage and polarity. If the polarity is set incorrectly, the LED will not work. If the voltage or current is too high, the service life of the LED will be greatly reduced.

LED lamps in the market are equipped with transformers to supply low-voltage power suitable for LEDs, and LEDs are fixed and installed at terminals from which specific voltages are output.

In this case, there are several disadvantages. LEDs are assembled in sizes with different outputs and color temperatures. If the user has purchased a specific LED. There is a high probability that the luminosity will not rise to the expected level. Not only may there be a large amount of light above the expected level, but there may also be a small amount of light below the expected level. Also, it is possible that one type of light does not meet expectations. Light may be too white or muted. Since LEDs are fixed and installed in LED luminaires, LEDs must only be replaced by specialists or all LEDs must be replaced. This is undesirable for the user. Furthermore, suppliers of LED luminaires must assemble and maintain different LED luminaires.

German utility model patent DE 299 15 140 U1 discloses an LED lamp that can be screwed or assembled. In this disclosure, electronic components for supplying power to the LED lamp may or may not be mounted to the LED lamp. The LED lamps of patent DE 299 15 140 U1 are replaceable and are suitable to be used as far as possible in LED luminaires equipped with transformers and rectifiers.

In the LED lamp disclosed in German utility model patent DE 299 15 140 U1, however, the light is emitted after the LED lamp is inserted into the internal socket. Therefore, the LED lamp is problematic in that overheating may occur because the internal heat is not discharged so that the damage period and the replacement period of the LED lamp may be shortened.

In addition, there is a problem of an increase in replacement cost because the entire LED lamp has to be replaced. Contents of the invention

Specific Embodiments of the Invention

The invention will be described in more detail with reference to the accompanying drawings showing embodiments of the invention.

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

As shown in FIGS. 1 and 2 , the LED lamp module 100 includes an LED lamp 1 and an assembly module 2 .

The LED lamp 1 , as shown in FIGS. 1 and 2 , includes an LED 3 , a bracket 4 , and a cover 5 .

The LED lamp 1 does not include a transformer and may include one or more of an LED driver D and a capacitor C to control the current. It is desirable to deliver current to the LED lamp through one or more of the LED driver D and capacitor C or directly connected to them. The LED 3 is shown in Figures 1 and 2 to be covered by a light transmissive sealing element and to have a spherical shape, but the LED 3 could have a different shape if desired.

A pair of electrical connectors 6 made of conductive material are formed at the bottom of the LED 3 .

The bracket 4 is made of cylindrical heat-conducting material. A space where one or more of the LED driver D and the capacitor C are placed is formed in the middle of the bracket 4 . The pair of legs 7 are electrically connected to the electronic connector 6 and protrude downward from the lower side. A bracket male screw unit 4A to which the cover 5 is screwed is formed on the outer peripheral surface of the bracket 4 . One or more LED drivers D or one or more capacitors C may be included. In short, the service life of the LED lamp 1 depends on the service life of the capacitor. That is, when the service life of the capacitor C for driving the LED lamp 1 is exhausted, the LED lamp needs to be replaced. For this reason, in the present invention, the auxiliary capacitor C is provided in the inner space of the bracket such that the auxiliary capacitor C assists the capacitor provided in the power supply device to deliver power to the LED lamp 1 . Therefore, the lifetime of the LED lamp 100 can be extended because the lifetime of the capacitor is extended.

The cover 5 has the shape of a disk which is perforated in the center and has an edge region at the bottom and extends downwards. A cap internal thread unit 5A is formed on the bottom inner surface of the cap 5 .

The assembly module 2 includes an assembly sleeve 21 , a fitting 22 , and an assembly shell 23 .

The fitting sleeve 21 includes an inner diameter corresponding to the outer diameter of the bracket 4 and has a cylindrical outer diameter corresponding to the fitting housing 23 . The heat dissipation grooves 30A are radially formed on the outer peripheral surface of the bracket 4 at a certain depth in the length direction, thereby forming the heat dissipation ribs 30 formed along the outer periphery of the heat dissipation grooves 30A. The bottom of the cooling rib 30 is screwed and processed to fit the sleeve male thread unit 21A. The assembly sleeve 21 can be made of aluminum (Al), copper (Cu), or a copper alloy with high thermal conductivity.

The outer diameter of the LED lamp 1 is formed smaller than the inner diameter of the assembly sleeve 21 so that the LED lamp 1 and the assembly sleeve 21 can be easily separated and the heat generated by the LED 3 can be easily discharged outward. The air gap G discharges the heat of the LED lamp 1 faster because the outer surface of the bracket 4 is in contact with the air, thus preventing the LED lamp from being damaged by heat. The preferred spacing between air gaps is about 0.1mm or higher so that heat can be easily vented and LED lamps can be easily replaced.

Fitting 22 is hollow cylindrical. A pair of contact electrode terminals 24 electrically connecting the legs 7 is formed in the fitting 22 and arranged to face each other. In addition, a pair of fitting openings 25 having an arcuate shape are formed at the top of the fitting 22 . The fitting opening 25 has a diameter enabling the insertion of the leg 7 at one end of the bow and has a smaller diameter than the leg 7 in the remaining area. Electrode terminal holes 22B for securing connection of external electric wires to the contact electrode terminals 24 are formed at positions outside the fitting 22 corresponding to the ends of the contact electrode terminals 24 . The fixing grooves 22H are formed at opposite sides of the fitting 22 and protrude toward the center with a certain depth. Fitting 22 having the structure described above may be made of insulating material, such as ceramic or reinforced plastic.

The assembly housing 23 is cylindrical with an open top and a closed bottom. The fitting case internal thread unit 23A is formed on the upper side of the inner wall of the fitting case 23 along the circumference of the fitting case 23 . A fitting case opening 31 for fixing the fitting case 23 or receiving an external electric wire is formed at the bottom of the fitting case 23 . At least one position fixing rod 23B protrudes from the closed bottom of the assembly case 23 so that the position fixing rod 23B from the closed bottom can be inserted into the fixing groove 22H. The assembly case 23 is made of metal material, such as aluminum (Al) with high thermal conductivity. The assembly housing 23 directly receives the heat generated by the accessory 22 and discharges the heat to the outside, thus further improving the heat dissipation efficiency.

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

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

As shown in Figures 3 and 4, in order to assemble the LED lamp module 100, the electronic connector 6 of the LED3 is inserted into the bracket 4 and connected to the LED driver D, and the power input terminal of the LED driver D is connected to the leg 7 and installed on the On the bracket 4 , and the cover 5 is screwed to the bracket external thread unit 4A formed on the upper side of the bracket 4 , thereby fixing the LED 3 to the bracket 4 . According to this, the LED lamp 1 is assembled and formed.

The fitting 22 is installed inside the fitting case 23 such that the position fixing rod 23B of the fitting case 23 is inserted into the fixing groove 22H. When the position fixing rod 23B is inserted into the fixing groove 22H, the fitting 22 is connected to the fitting case 23 so as not to interfere with wiring of electric wires.

After the fitting 22 is connected to the assembly housing 23, the leg 7 of the LED lamp 1 is inserted into the fitting opening 25 of the fitting 22 and then rotated and connected there. Here, the legs 7 are electrically connected to the respective contact electrode terminals 24 inside the fitting 22, and the bottom of the leg 7 having a wider diameter is supported by the inner surface of the fitting 22 so that the leg 7 is not separated from the fitting case opening 31 . Thus, the leg 7 remains fixed to the fitting 22 . Such a connection is called a GU bayonet connection. The GU bayonet connection is a common connection between a luminaire and an assembly module in the lighting industry.

The connection of the accessory 22 and the LED lamp 1 is not limited to a GU bayonet connection. It is evident that the connection of the LED lamp 1 and the fitting 22 in the LED lamp module 100 can be realized in a similar manner between the LED lamp 1 and the assembly module 2 by means of connectors, such as Edison screws or BA bayonet connections .

Next, after the assembly sleeve 21 is inserted into the LED lamp 1, the assembly sleeve external thread unit 21A formed on the lower side of the assembly sleeve 21 and the assembly case internal thread unit 23A of the assembly case 23 are connected so that the LED lamp module The assembly of 100 is completed. The process of connecting the fitting sleeve 21 to the fitting case 23 can be carried out regardless of the fixing of the LED lamp 1 to the fitting 22 . [69] During the assembly process of the LED lamp module 100 , the heat dissipation groove 30A formed on the outer surface of the assembly sleeve 21 is separated from the internal threaded unit 23A of the assembly case, thus forming several heat dissipation holes 40 . Therefore, the heat generated inside the LED lamp module 100 is not only conducted through the assembly shell 23 and the assembly sleeve 21 , but also discharged through the heat dissipation holes 40 . Therefore, heat dissipation efficiency can be significantly improved.

Furthermore, in the assembled LED lamp module 100, the leg 7 of the LED lamp 1 remains fixed to the fitting 22 by means of a GU bayonet connection. In addition, the LED lamp 1 can be freely moved up and down in the assembly sleeve 21 , and the assembly sleeve 21 simply supports the LED lamp 1 in the horizontal direction. When the GU bayonet connection is released in the LED lamp module 100 having the above structure, the LED lamp 1 can be freely separated from the LED lamp module 100 . Therefore, consumers can easily replace the damaged LED lamp 1 without separating the assembly sleeve 21 from the LED lamp 1 .

The LED lamp module 100 having the above structure can be arranged to face the place where the electrical contact is formed, for example, between the electronic connector 6 and the inner side wall of the through hole 4B and between the leg 7 and the inner side wall of the through hole 4B, by Made of conductive material.

If the mounting module 2 according to the present invention is mounted to an LED lamp module, the user can have a very easy easy configuration by selecting an LED lamp comprising LEDs with desired brightness and color and replacing the existing LED lamp with the selected LED lamp. The brightness and color of lights required. Therefore, the user does not need to rely on the LED luminaire selected by the supplier in the brightness and color of the light.

In addition, the LED lamp module 100 of the present invention can be assembled into different lighting fixtures. 5 to 7 show a downlight LED lamp 200 and an LED lamp 300 for a ceiling, selected from the lighting fixtures.

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

The downlight LED lamp 200 in FIG. 5 includes a lampshade 220 , a reflector 210 , a power supply unit 230 , and an LED lamp module 100 . The lampshade 220 has an open bottom and has a round or polygonal shape. The reflection plate 210 has a shape corresponding to the lamp cover 220 inside the lamp cover 220 and has a mounting hole 212 at the top thereof. The power supply unit 230 is formed on the top surface of the downlight LED lamp 200 which is buried in the surface of the ceiling or wall. The LED lamp module 100 is inserted into the mounting hole 212 and then fixed and connected to the upper surface of the lamp cover 220 so that it is electrically connected to the power supply unit 230 .

The downlight LED lamp 200 may include one or more mounting holes 212 such that the LED lamp module 100 is inserted into the one or more mounting holes 212 .

The downlight 200 of FIG. 5 has the advantage that the service life is extended through the heat dissipation function of the LED lamp module 100 and is easily managed with low maintenance cost because only the relevant LED lamp needs to be replaced when the LED lamp 1 is damaged.

6 is a bottom view of an LED lamp 300 for a ceiling in which the LED lamp module 100 of FIGS. 1-4 is applied, and FIG. 7 is a cross-sectional view of the LED lamp 300 for a ceiling of FIG. 6 .

As shown in FIGS. 6 and 7 , an LED lamp 300 for a ceiling includes a ceiling lamp shade 310 in which the downlight LED lamps 200A are arranged in a lattice and the downlight LED lamps 200A can be assembled to have different structures, for example, including individual LED lamps 1 The structure and the structure comprising two or more LED lamps 1.

An LED lamp module and an LED lamp according to another embodiment of the present invention are described below.

Fig. 8 is an exploded view of an LED lamp module 100A including a heat dissipation unit 50 according to another embodiment of the present invention (hereinafter referred to as "second LED lamp module 100A"). FIG. 9 is an exploded cross-sectional view of the second LED lamp module 100A of FIG. 8 . FIG. 10 is a perspective view of an assembled state of the second LED lamp module 100A of FIGS. 8 and 9 . FIG. 11 is a cross-sectional view of the second LED lamp module 100A of FIG. 10 .

As shown in Figures 8-11, the second LED lamp module 100A further includes an assembly housing 23a, wherein the lower assembly housing internal thread unit 24A is formed on the inner peripheral surface of the assembly housing 23 of the LED lamp module 100 in Figure 1 and the heat dissipation unit 50 Is screwed to the lower assembly housing internally threaded unit 24A.

A heat dissipation hole 27 is formed at the bottom center of the assembly case 23a.

The heat dissipation unit 50 is tubular. The heat dissipation unit external thread unit 51A is formed on the heat dissipation unit 50 top and is screwed to the assembly case internal thread unit 24A of the lower assembly case 23A, and several heat dissipation unit ribs 52 protrude and are formed on the outer peripheral surface of the heat dissipation unit 50 so that they are The heat dissipation unit groove 50A is formed in the vertical direction.

If the second LED lamp module 100A having the above structure is connected to a lamp installed on the ceiling, the heat dissipation unit 50 can more easily dissipate the heat of the second LED lamp module 100A because it is exposed to the inner side of the ceiling.

In FIGS. 8 , 9 , and 10 , the assembly case 23 a and the heat dissipation unit 50 are illustrated as being screwed together, but the assembly case 23 a and the heat dissipation unit 50 may be integrally formed.

As shown in FIG. 12, the second LED lamp module 100A of FIGS. 8 to 11 is applied to a downlight, thus forming a second downlight lighting fixture 200B.

As shown in FIG. 13, the second LED lamp module 100A of FIGS. 8 to 11 is applied to a ceiling LED lamp, thus forming a second LED lamp 300A for a ceiling.

The LED lamp shown in FIGS. 1-13 may include a cover 5 having a reflector 5a in the shape of a Korean hat to further improve the heat dissipation function.

14 is an LED lamp including a reflector 5a having a Korean cap according to a modified embodiment of the present invention, and FIG. 15 is a perspective view of an LED lamp module to which the LED lamp of FIG. 14 is applied.

As shown in FIG. 14 or 15, the cover 5 formed on the LED lamp module 100, 100A may further include a Korean cap mirror 5a. The Korean hat mirror 5a is made of metal material, such as aluminum (Al) with high thermal conductivity, so that the Korean hat mirror 5a can directly receive the heat generated by the LED3 and the bracket 4 fixing the LED3 and discharge the heat.

The LED lamp modules 100 and 100A and the lighting fixtures 200, 200A, 200B, 300 and 300A of the present invention have the special advantages and optimized service life of LED lamps. A properly assembled and replaced LED lamp 1 is very useful and can be connected to a suitable power source for a suitable LED lamp, eg low direct current delivery for the necessary voltage and current. LEDs can be operated under optimized conditions, such as the amount of light obtained at a distance and lifetime due to good heat conduction.

As with other light sources, LEDs use a small output, with a small ratio of output to heat conversion. However, small surface areas of LEDs can be rapidly induced to high temperatures.

Therefore, the heat conduction performance of transferring heat from the LED to the outer surface of the bracket and the heat dissipation efficiency of discharging the internal heat through the heat dissipation holes have been significantly improved. Therefore, the lifetime of the LED can be greatly increased because the LED can be operated at a lower temperature.

In a preferred embodiment, the stent is preferably shaped as a thick wall. This has a positive effect on thermal performance and heat transfer. A preferred bracket is made of a material with good thermal conductivity, such as aluminum (Al). Aluminum (Al) is the preferred electrical conductor, so the electrical insulation between the bracket and the terminals and the conductors used to supply power to the LED must be secure.

In another useful embodiment according to the present invention, although not shown in the figures, electronic components electrically connected to wires for supplying power to the LEDs may be received in recesses in the body of the bracket. If the electronics include a dimmer circuit connected to a temperature sensor, the lamp system can be operated with a maximum amount of light produced and cooling effect with respect to maximum output and size.

When the temperature exceeds a predetermined limit, the dimmer circuit dims the light of the LED so that the LED generates less heat. In addition to the temperature sensor and dimmer circuit, a control circuit for providing dimming when the temperature sensor signal exceeds a limit value is also provided. If the electronic component includes circuitry for switching the polarity of the voltage, a voltage of the correct polarity need not be supplied to the LED. This is because this circuit corrects for possible voltage polarity.

In a more efficient embodiment of the LED lamp module according to the invention, the bracket and the mounting module are arranged to comprise a common contact surface where they contact each other when the bracket and the mounting module are mounted as elements for a surface.

The heat conduction from the bracket to the assembly module takes place through the air gap between the bracket and the assembly module. The cooling of the LED is further increased according to the reduction of the spacing between the air gaps and the increase of their area. The spacing and area of the air gaps are considered by design with conventional machining precision, maximum heat transfer energy, target management temperature of the bracket, etc. Therefore, the heat transfer between them can increase according to the increase of temperature. Furthermore, when the heat sink 30A is formed, the outer surface area of the bracket is further increased such that the heat transfer from the bracket to the mounted module is further increased. When the assembly sleeve 21 and the assembly case 23 are connected to form the cooling hole 40, the cooling of the LED can be further accelerated because the heat generated by the LED lamp module 100 can be discharged faster.

In a preferred embodiment, the mounting module comprises a mounting housing having a predominantly outer cylindrical shape. The cylindrical diameter of the assembly module may have a range of 26mm-28mm, 38mm-40mm, or 50mm-54mm. The fitting openings of the fitting internal thread M10xl are formed from the end of the fitting shell to a position away from the place where the shell is installed, and their size is close to the size of the fitting module.
