LED lighting apparatus to improve heat discharge and luminous intensity function

The present invention relates to an LED lighting device with improved heat dissipation and illuminance, and more particularly, to quickly discharge heat generated from various street lights, tunnel lights, picking lights, warning lights, traffic lights, flood lights, and the like, so as not to cause problems even when used for a long time. In addition, the angle can be adjusted to a variety of angles to be used in accordance with the use of various lighting devices, thereby significantly improving the quality and reliability of the product to allow users as a consumer to plant a good image.

As is known, the LED lighting device is provided with an LED lamp mounted on the LED PC so that light is emitted. Compared with a general incandescent lamp or a luminaire such as a luminaire, the power consumption is low, the power control characteristics are good, the light emitted can be easily controlled, and can be provided in a variety of configurations, it is being applied to various will be.

However, since such LED lighting device is weak in intensity of light emitted from one LED lamp, when used as a lighting device, a plurality of LED lamps are mounted on the PC.

In this LED lamp, the lead wire of the LED body is fixed to the LED PC, and the LED body includes a plurality of members for emitting light. Thus, when light is emitted from the LED lamp, a lot of heat is generated in the LED lamp and the LED body.

However, in the conventional LED lamp, a structure for heat dissipation can be provided only on the back side of the LED, which is the opposite side where the LED lamp is not installed, and the LED lamp side cannot have a heat dissipation structure because light must be emitted to the outside. . Therefore, the heat generated from the LED lamp and the LED body is not radiated, which causes a problem that the entire LED lighting device is overheated.

In particular, there is a problem that the efficiency caused by the LED lamp is lowered due to overheating in the conventional LED lighting device. In addition, there is a problem that the life of the LED lamp is also reduced due to overheating.

In order to solve the above problems, Patent Registration No. 0880262 (Application No. 10-2008-0090690) (name: LED lighting device having a heat dissipation structure) has been registered. That is, the conventional technique is as shown in Figure 1 (a) (b) (c) (d) (e) The LED lighting device (A) is provided with an LED case 21 for installing the LED (11) and the LED lamp 12, is located inside the LED case 21 and the LED (PC) 11 and the The heat transfer medium 22 is provided to surround the LED lamp 12. In addition, the heat sink 31 is coupled to the outer surface of the LED case 21 is characterized in that it is provided. In this case, the LED case 21 may be provided to have a sealed structure when the heat transfer medium 22 is provided in a liquid or gel state, and the heat transfer medium 22 having a hardened state is provided in a molded form. In this case, only the part in contact with the heat sink 31 may be provided with the LED case 21, the portion where the LED lamp 12 is located may be provided to be exposed. Therefore, heat generated from the LED lamp 12 and the LED PC 11 is transmitted through the heat transfer medium 22 to radiate heat from the heat sink 31. In the accompanying drawings, the LED case (11) and the LED lamp 12 will be mainly described by illustrating that the LED case 21 is provided to be wrapped and sealed, and in other cases may be applied by analogy It is natural. The LED lighting device using the LED lamp 12 is that the LED lamp 12 is mounted on the LED PCB (LEDs PCB, electronics Light Emitting Diode Printed Circuit Board), one LED lamp on one LED 12 may be mounted, and a plurality of LED lamps 12 may be mounted and used. Since the LED lamp 12 may not cover the light emitted from the LED lamp 12 in the direction in which the LED lamp 11 is mounted, the structure for cooling the LED lamp 11 is mostly the LED lamp 12. It may be arranged on the other side that is not installed. However, most of the heat is that a large amount of heat can be generated in the LED body for mounting the LED lamp 12 and the LED lamp 12 to the LED. Accordingly, the heat generated from the LED body 121 and the LED lamp 12, which is the front surface of the LED PC 11, is transferred to the heat transfer medium 22, and the heat received by the heat transfer medium 22 is the LED case 21. It is provided to be cooled by the heat sink 31 coupled to the LED upper case (23). The LED case 21 for this purpose is provided with an LED upper case 23 in surface contact with the heat dissipation plate 31 and the LED lower case 24 in which the LED lamp 12 is wrapped. Thus, the internal heat transfer medium 22 is not separated by the LED case 21 including the LED upper case 23 and the LED lower case 24. The heat transfer medium 22 wraps around the LED PCB (11), LED lamp 12 and LED body 121 as a whole, so as to contact and wrap the LED PD (11), LED lamp 12 and LED body All heat generated at 121 may be transferred to the heat transfer medium 22. Therefore, all of the heat caused by the lighting of the LED lamp 12 is transferred to the heat transfer medium 22, so that the overheating phenomenon of the lighting of the LED lamp 12 does not occur. And the edge of the LED case 21 and the LED lower case 24 of the LED case 21 is provided so that the sealing packing member 25 is surrounded, so that the heat transfer medium 22 is not separated It is provided. Therefore, the LED case 21 of the LED case 21, the LED upper case 23 and the sealing packing member 25 has a completely sealed structure, so that the light emitted from the LED lamp 12 is the outer front Since it should be reflected in the direction, the LED lower case 24 may be made of a transparent material. Of course, it may be provided with a transparent plastic material, a transparent glass material, a transparent epoxy material, a transparent urethane material and the like. In addition, when the LED lower case 24 is provided as an opaque material or a metal material, only the portion where the LED lamp 12 is positioned may be provided so that the see-through window member made of the transparent material listed above is combined. That is, the LED lower case 24 is a portion in which the LED lamp 12 is located made of a transparent material, it is provided to have a sealed structure in the combined state with the LED upper case (23). On the other hand, the LED upper case 23 may be made of a transparent material while being made to have a sealed structure, and may also be made of a translucent or opaque material. In addition, the LED lamp 12 emitting colors may be used as well as the light emitted from the LED lamp 12 to have a color. The LED sub-case 24 has a color or translucent material, and furthermore. Embossing may be made of a material or the like to be formed to have a more aesthetic sense. In addition, when the heat transfer medium 22 is made of liquid, the LED case 21 may be provided with a liquid inlet 211 for injecting the heat transfer medium 22 of the liquid. In addition, the wiring connection part 212 for supplying power to the LED PC 11 from the outside may be provided together. In addition, the LED lower case 24 of the LED case 21 is provided with a lamp protrusion cover 27 protruding outward so that a lamp insertion groove 26 for inserting the LED lamp 12 is formed. It could be. Therefore, while reducing the overall thickness of the LED lower case 24, only the lamp projection cover portion 27 may be formed in an arc shape to give a more aesthetic sense. In addition, the LED case 21 may be provided with a receiving partition 29 for forming a plurality of heat transfer medium receiving space (28). In addition, the LED case 21 may be provided with an installation unit 215 for fastening to an external luminaire (not shown), and the upper LED case 23 or the LED lower case 24 is disposed inside the LED upper portion.
