In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view showing an LED lamp device according to a first embodiment of the present invention.

As shown in FIG. 1, the LED lamp device of the present invention absorbs heat generated by the LED chip 10 from the rear surface of the circuit board 20 on which the LED chip 10 is mounted, thereby absorbing the LED chip 10. And a heat dissipation substrate 30 for naturally cooling the circuit board 20 using aluminum or copper material.

The circuit board 20 is a thin plate on which electrical components such as light emitting diodes are mounted, and a first film 24 and a second film 26 are formed as insulators on upper and lower sides of a pad 22 made of copper foil. It is. Here, the pad 22 is a portion plated with copper and is a portion to which a lead wire connected to the outside can be connected or a portion to which a probe can be connected.

The first film 24 is a thin plastic coating film applied on the pad 22. On the other hand, the second film 26 in contact with the heat dissipation substrate 30 is an opaque surface for supporting the pad 22, and a plate panel made of plastic material having a predetermined thickness or more that electrically insulates the pad 22 and the heat dissipation substrate 30. It may be made of.

Accordingly, the circuit board 20 mounts the LED chip 10 on the pad 22 on the second film 26 or is connected to the pad 22 to protrude above the first film 24. It can be formed to be.

 The light emitting diode chip 10 has an energy efficiency of 95% or more, which is significantly higher than that of incandescent bulbs and fluorescent lamps. The light emitting diode chip 10 is largely classified into a SMD type and a lamp type.

The light emitting diode chip 10 to be described below will be described with respect to the lamp type. Although not shown, there are two feet under the light emitting diode chip 10, which serve as electrodes.

Inside the mold, there are a negative electrode and a positive electrode for supplying power to the semiconductor chip, and the semiconductor chip is mounted on one of them. Thin gold wires are used to connect this electrode to the semiconductor chip. The semiconductor chip is basically a PN junction diode of a III-V compound semiconductor. Group III-V compound semiconductors are made by combining elements of Groups III and V on the Periodic Table of Elements and have an advantage that the luminous efficiency is nearly 95% or more.

However, the light emitting efficiency of the LED chip 10 may vary depending on the ambient temperature. This is because the resistance increases as the temperature increases due to the characteristics of the semiconductor and the conductor. Therefore, the LED chip 10 and the circuit board 20 may be naturally cooled by the heat dissipation board 30 made of aluminum or copper, which is in contact with the circuit board 20 on which the LED chip 10 is mounted. have.

The base 40 and the lens 50 are formed on the circuit board 20 with the light emitting diode chip 10 at the center. The lens 50 is used to distort the light from the object by grinding the surface of a transparent material such as glass into a spherical surface, and is a transparent body that mixes and disperses the light emitted from the LED chip 10. For example, the lens 50 includes a convex lens that emits light propagated to the upper portion of the LED chip 10.

Meanwhile, FIGS. 2 and 3 show combined perspective views of FIG. 1. 4 and 5 show the light dispersion ranges of FIGS. 2 and 3, respectively.

It is formed to have a plurality of convex spherical surfaces 54 for refracting the light in a plurality of directions.

Here, the single convex sphere 52 proceeds while radially spreading light in one direction with respect to one spherical end corresponding to the center of the lens 50 or the base 40 as shown in FIG. 4. (Dispersion range of light-reference A).

On the other hand, as shown in FIG. 5, the plurality of convex spheres 54 may propagate light radially in a plurality of directions with respect to the ends of the plurality of spheres (dispersion range of light-reference B).

As a result, the brightness of the road surface is evenly distributed, and the uniformity is improved.

As such, since the lens 50 may be implemented to disperse the light traveling direction in various ways according to the number of spherical surfaces, the spherical surface of the lens 50 may be selectively formed as a single convex sphere or a plurality of convex spheres according to the road surface state. It is preferable.

And a cap ring 44 for fixing 50. Here, the base ring 42 is bonded to the circuit board 20 around the light emitting diode chip 10 by an electrocompression method.

In addition, the base ring 42 and the cap ring 44 are formed to seal the light emitting diode chip 10 therebetween with the lens 50 interposed therebetween. Therefore, the base 40 and the lens 50 are formed so that the light emitting diode chip 10 mounted on the circuit board 20 is not affected by the environment from the outside.

As described above, the heat dissipation substrate 30 that absorbs heat generated from the light emitting diode chip 10 and naturally cools the second film of the circuit board 20 facing the base 40 and the lens 50. 26) It is in contact with the bottom. In particular, since the heat dissipation substrate 30 in contact with the second film 26 made of plastic is made of a copper component having excellent corrosion resistance, it is possible to minimize chemical reactions and deteriorate while being heated by external influences such as ultraviolet rays. It can prevent.

LED lamp device according to the first embodiment of the present invention, by using a heat-dissipating substrate 30 made of copper-free oxygen-free copper material excellent in corrosion resistance to prevent degradation from external influences such as ultraviolet rays to increase or maximize durability can do.

Although not shown, the LED lamp device is formed to be protected by a case opening the upper portion of the lens 50 for dispersing the light emitted from the LED chip 10.

According to the first embodiment of the present invention, to improve the heat dissipation effect, the material of the heat dissipation substrate is made of aluminum or copper and is formed of a circular substrate to maximize the heat dissipation area of the close contact portion. In addition, in the case of a circular substrate, when using a plurality of LED lamps, there is no need for a separate mechanism to orient. For example, the rectangular or polygonal radiating board has a disadvantage that the appearance is not beautiful unless the direction is constant.

In addition, the structure of the conventional LED lamp is a simple convex lens, it was difficult to control the irradiation range and angle of the light, but the use of a lens with a plurality of convex lenses is effective to control the irradiation range and direction of the light.

A thermoelectric element such as a Peltier element can switch endothermic heat according to the current direction, and the endothermic heat amount can be adjusted according to the amount of current, and thus can be employed in the cooler 130 having a low capacity.

Accordingly, the LED lamp device according to the third embodiment of the present invention forms a cooler 130 under the circuit board 120 opposite to the LED chip 110 to remove heat generated from the LED chip 110. Since the light emitting efficiency of the LED chip 110 can be increased or maximized.

In addition, the cooler 130 is charged in the case 140 that protects the LED chip 110 and the circuit board 120 from the outside. Although not shown, the cooler 130 and the circuit board 120 are formed to be insulated by the case 140 and the heat insulating material.

This is because the cooler 130 may independently cool the LED chip 110 and the circuit board 120.

For example, the case 140 may be fixed to a wall, and the case body 142 may open the LED chip 110 and the circuit board 120 to one side, and the LED chip 110 and the circuit opened from the case body 142.

The RFID reader 180 reads and reads RFID tag information including identification information of the RFID tag, dimming information of LED lamps, perfume name information, and sound source reproduction information whenever it recognizes an RFID tag entering a preset area. .

The perfume box 190 is provided on one side of the LED lamp device, the perfume is fresh water, and one side is provided with a first injection port through which the perfume is sprayed.

The perfume box 190 includes a plurality of perfume packs each partitioned so that a plurality of perfumes can be isolated and desalted inside the perfume box, and the perfume movement to provide each of the perfumes contained in each perfume pack to the first injection hole. It includes a passage.

On the other hand, looking at the internal configuration of the LED lamp device according to the third embodiment, the present invention according to the third embodiment is an RFID reader 180, dimming control unit, perfume box, perfume pump, perfume pack, perfume valve, perfume It includes a moving passage, a first injection port, a speaker, a sound source playback unit.

The perfume pumping unit processes the perfume corresponding to perfume name information (eg, aroma, rose, etc.) obtained from the RFID reader 180 to be injected.

In more detail, the perfume pumping unit searches for a perfume pack containing the perfume in accordance with the perfume name information obtained from the RFID reader 180, and turns on the valve provided on the lower surface of the perfume pack. Signal) to generate and transmit.

Thereafter, the valve received 'valve on signal' from the perfume pumping part is opened, and perfume is supplied to the first injection hole through the perfume movement passage connected to the valve and sprayed.

In this case, the sound source reproduction information may be any one of jazz, classic, ballad, hip hop, song, folk song, and Choi.

Meanwhile, a convex lens 150 that emits light emitted from the LED chip 110 is formed inside the case 140. The convex lens 150 has a convex surface formed in a direction in which light emitted from the LED chip 110 travels.

12 is an enlarged cross-sectional view of the base ring 162 shown in FIG.

11 and 12, a single layer 170 perpendicular to the circuit board 120 is formed on the lower slope of the base ring 162. In addition, a plurality of LED chips 110 are formed in an inner region of the single layer 170, and the yag 112, which is a compound that changes the wavelength of light emitted from the LED chips 110, is the single layer 170. It is filled up to the height of.

The yag 112 is a compound for changing the wavelength of light generated by the LED chip 110 and is typically used in a state of being mixed with transparent silicon.

The single layer 170 is a region formed to more easily control the thickness of the yag 112 filled in the base ring 162. That is, by adjusting the height of the single layer 170, it is possible to adjust the thickness of the yag 112 filled therein.

Therefore, in the related art, the thickness of the yag is increased by filling the mixture of the yag and the transparent silicon in the entire area of the base ring, thereby resulting in an inefficient optical characteristic and a high cost.

However, in the third embodiment of the present invention, as shown in FIG. 11 and FIG. 12, a single layer 170 having a predetermined depth is formed at the bottom of the base ring 162 and corresponds to the height of the single layer 170. By forming the yag 112 only in thickness, it is possible to more easily control the thickness of the yag 112 to the desired thickness, thereby increasing the light efficiency and also reduce the production cost.

The LED chip 110 has an energy efficiency of 95% or more, which is significantly higher than that of an incandescent light bulb and a fluorescent lamp having an energy efficiency of 5% and 25%, respectively. Therefore, the LED chip 110 is called a light emitting diode, and is largely classified into a SMD type and a lamp type.

The LED chip 110 to be described below will be described with respect to the lamp type. Although not shown, there are two feet under the LED chip 110, and these two feet serve as an electrode. Inside the mold, there are a negative electrode and a positive electrode for supplying power to the semiconductor chip, and the semiconductor chip is mounted on one of them. Gold wire is used to connect the electrode and the semiconductor chip.

The semiconductor chip is basically a PN junction diode. Whereas silicon PN junctions were the key to the electronic information revolution, PN junctions of group III-V compound semiconductors are the key to the light revolution. Group III-V compound semiconductors are made by combining elements of Groups III and V on the Periodic Table of Elements and have an advantage that the luminous efficiency is nearly 95% or more. However, the light emitting efficiency of the LED chip 110 may vary depending on the surrounding temperature. This is because the resistance increases as the temperature increases due to the characteristics of the semiconductor and the conductor.

Therefore, the LED lamp apparatus according to the third embodiment of the present invention can increase or maximize the luminous efficiency because the LED chip 110 can be cooled to a temperature below a predetermined level by using the cooler 130.

The circuit board 120 for mounting the LED chip 110 includes a conductive metal such as copper or aluminum having excellent conductivity. The conductive metal may serve to transfer the heat generated by the LED chip 110 to the cooler 130. At this time, the upper and lower portions of the cooler 130 is formed with a thermal pad 132 for increasing the thermal conductivity. In addition, the area | region except the cooler 130 is heat-insulated by the heat insulating material 122 between the case 140 and the circuit board 120. FIG. As described above, the circuit board 120 and the case 140 are thermally independent from each other.

Therefore, the circuit board 120 and the LED chip 110 inside the case 140 are formed to independently control the temperature. Although not shown, the cooler 130 may include a temperature sensor that senses a temperature of the circuit board 120 or the LED chip 110, and a control signal that controls the operation of the thermoelectric element according to the temperature detected by the temperature sensor. It further comprises a control unit for outputting. Here, the temperature sensor includes a thermocouple made of a device having a Seebeck effect.

In this case, the temperature sensor may be formed to contact the circuit board 120. Therefore, the temperature sensor and the controller are configured to sense the temperature of the LED chip 110 and the circuit board 120 and operate the thermoelectric element to cool the LED chip 110 and the circuit board 120 to a predetermined temperature. have.

In addition, the circuit board 120 and the LED chip 110 may be prevented from being excessively cooled by the thermoelectric element.
