Description

[0001] The present invention relates to a bulb type LED lightening apparatus,

The present invention relates to a bulb-type LED lighting device, and more particularly, to a bulb-type LED lighting device in which an entire assembly process can be performed quickly and easily, and heat is mainly emitted to a rear side, not a front side with an illumination head.

2. Description of the Related Art In recent years, LED lighting devices have been applied not only to vehicle lighting such as vehicle interior lamps, license plates, trunks, side mirrors, and the like but also various other applications. As a part of this, an LED illumination device has been disclosed in Korean Patent No. 1472463 (issued on December 15, 2014). However, the LED illumination device here is disadvantageous in that the assembling process is inconvenient and the heat is emitted from the head of the illumination light, so that there is a lot of heat near the illumination at the time of installation.

1 and 2 are diagrams for explaining an LED illumination device 1 disclosed in the above-mentioned conventional Korean Registration No. 1472463 (published on Dec. 15, 2014), and for the purpose of comparison with the present invention, The name of the element has been partially changed.

Referring to Figs. 1 and 2, the connection terminal 20 is installed by being fitted from the inside to the inside of the illumination case 10 from the top to the bottom. Since the upper end of the connection terminal 20 is bent obliquely outwardly to form the contact portion 25 so that the contact portion 25 can pass through the connection terminal 20 from the top to the bottom, The connection terminal guide penetration portion 13 must necessarily be formed long in the longitudinal direction. The connection terminal 20 is fitted downward until the contact portion 25 is seated on the inclined surface 14 formed on the upper surface of the flange portion 11 of the illumination case 10. [

The LED substrate 50 on which the LEDs 60 are mounted and the PCB substrate 30 on which the driving circuit for emitting the LEDs 60 are mounted are assembled to each other through the coupling bundle 40. At this time, the LED substrate 50 is installed horizontally in the illumination case 10, and the PCB substrate 30 is installed vertically below the LED substrate 50.

The assembly process is as follows.

First, the connection terminals 20 are fitted from the top to the bottom in such a manner that the connection terminals 20 are firmly fitted to both sides of the inside of the illumination case 10.

Next, both sides of the PCB substrate 30 assembled on the LED substrate 50 are inserted into the connection terminal 20 and pressed down to fix the PCB substrate 30 in the illumination case 10.

The fixing projection 71 projecting downward from the illumination cap 70 is inserted into the fastening hole 12 formed at the upper end of the side wall of the illumination case 10 so that the illumination cap 70 is inserted into the illumination case 10, To complete the assembly.

However, the above-described conventional LED illumination device 1 has the following problems as shown in Fig.

First, since it is very inconvenient to insert the connection terminals 20 into both sides of the inside of the illumination case 10, there is a drawback in that the skilled operator has a high concentration of power and time. This is a further disadvantage when the size of the connection terminal 20 is small.

Secondly, since the illumination cap 70 easily escapes from the illumination case 10, bonding between the illumination cap 70 and the illumination case 10 through the adhesive agent is cumbersome. In addition, since the adhesive must harden in order for the adhesive to exhibit its performance, it takes a long time to dry the adhesive in this process, so that it takes a long time to complete the assembly. In addition, in the case of using such an adhesive, once assembled, it is difficult to disassemble, and even if the diaphragm is decomposed, the joint between the illumination cap 70 and the illumination case 10 is damaged and reassembly is difficult. .

Thirdly, since the connection terminal guide penetration portion 13 must be formed with respect to the interval h between the illumination cap 70 and the flange portion 11, the connection terminal guide penetration portion 13 is unnecessarily large, The heat generated inside the connection terminal guide penetration portion 13 is discharged in a large amount forward. Therefore, the vicinity of the head of the lighting is very hot, and therefore, when used in, for example, a ceiling of a vehicle interior, heat becomes considerable in the vicinity of the lighting.

An LED substrate mounted horizontally in the illumination case and having an LED mounted on an upper surface thereof;

A PCB substrate mounted on the LED substrate and mounted vertically below the LED substrate, a driving circuit for emitting light of the LED is mounted,

A contact portion is formed to be fitted on both sides of the PCB substrate for electrical connection with the PCB substrate and the upper end is bent outwardly to be electrically connected to a terminal of the socket and the contact portion is inserted into the contact portion drawing- A connection terminal installed to be exposed to the outside; And

An illumination cap having wings formed on both sides thereof, the wings being inserted into the wing insert holes so as to be positioned on the LED substrate, And a control unit.

The wing insert hole is preferably disposed to be out of alignment with the contact portion drawing hole so as not to be divided into right and left by the right case and the left case.

Preferably, an air hole is formed in the bottom of the illumination case, the air hole being divided into right and left by the right case and the left case.

It is preferable that an air hole is formed in a portion of the LED substrate where the LED is absent.

And an LED substrate fitting groove is formed below the wing insert hole so that the LED substrate can be laterally inserted into the inner circumferential surface of the illumination case.

The fastening protrusion is formed in one of the right case and the left case and the fastening protrusion is formed in the other case so that the right case and the left case are coupled by the fitting of the fastening protrusion and the fastening hole.

Preferably, the contact portion is horizontally laid horizontally.

In the LED lighting apparatus according to the present invention, the lighting cap may be provided such that the wing portion is fitted into the wing insertion hole from the inside to the outside of the lighting case, And is inserted and installed.

According to the present invention, since the right case and the left case are laterally coupled with each other in a state where the connection terminal is coupled to the PCB substrate, the inconvenience of assembling the connection terminal as in the conventional art is eliminated.

In addition, since both the wings of the illumination cap are fitted and fixed to the wing insert hole in the process of assembling the left case and the right case in the lateral direction, the lamp cap can be assembled firmly without detaching the lamp cap without using the adhesive.

In contrast to the conventional case where the connection terminal is inserted from the top to the bottom, since the connection terminal is sandwiched between the left case and the right case laterally, the contact portion can be formed so as to penetrate only the necessary portion. The height of the draw-out hole is lower than that of the conventional one, so that heat emission through the contact-portion draw-out hole can be minimized.

In addition, since most of the heat is emitted to the outside through the air vent formed in the bottom of the lighting case, the heat of the LED lighting device is ultimately emitted to the rear side rather than the front side of the socket. The heat near the head of the light can be reduced.

The lighting case 110 has a hollow space therein and a wing insertion hole 112 is formed on both sides of the upper portion and a contact portion drawing hole 113 is formed on both sides so as to be positioned below the wing insertion hole 112. The contact portion drawing-out hole 113 has an upper limit and a lower limit so that the upper end and the lower end are clogged. The illumination case 110 is vertically cut so that the contact portion drawing-out hole 113 is divided into left and right sides to be divided into a left case 110a and a right case 110b.

Air holes 180 are formed in the bottom of the lighting case 110. The air holes 180 are formed in the left and right sides of the left case 110a and the right case 110b in order to increase the area occupied by the air holes 180. [ It is preferable that it is formed to be divided.

The fastening protrusion 116a is formed in one of the left case 110a and the right case 110b and the fastening hole 116b is formed in the other of the left case 110a and the right case 110b to be engaged with the fastening protrusion 116a and the fastening hole 116b A lateral coupling of the left case 110a and the right case 110b is achieved.

The LED substrate 150 is installed horizontally in the illumination case 110 and the LED 160 is mounted on the upper surface. The PCB substrate 130 is mounted on the LED substrate 150 through the bonding bundle 140 and vertically installed under the LED substrate 150. The driving circuit for emitting the LEDs 160 is mounted. A bundle coupling hole 151 is formed in the LED substrate 150 and a bundle coupling hole 131 is formed in the PCB substrate 130 for coupling with the coupling bundle 140.

Here, the bonding bundle 140 is merely an optional configuration, and the LED substrate 150 and the PCB substrate 130 may be directly coupled to each other through various methods without using the defect bundle 140.

It is preferable that an air through hole 152 is formed in a blank portion where the LED 160 is not provided on the LED substrate 150.

The connecting terminal 120 is provided with a holding part 126 for preventing the PCB 130 from being pushed in and the connecting terminal 120 is tightly held on both sides of the PCB 130 through the holding part 126 And is electrically connected to the PCB substrate 130.

The upper end of the connection terminal 120 is bent outward so as to be electrically connected to the terminal of the socket to form the contact portion 125. The connection terminal 120 is installed so that the contact portion 125 is inserted into the contact portion drawing-out hole 113 and exposed to the outside. At this time, it is preferable that the contact part 125 is horizontally placed horizontally. The contact portion 125 is located on the seating portion 114 formed on the upper surface of the flange portion 111.

The lighting cap 170 is formed with wings 171 on both sides and the wing portion 171 is inserted into the wing insertion hole 112 to be positioned on the upper portion of the LED substrate 150, Respectively.

The wing insert hole 112 is not divided into the right case 110a and the left case 110b unlike the contact portion drawing-out hole 113 divided by the left case 110a and the right case 110b desirable. For this, the wing insert hole 112 is preferably disposed to be displaced from the contact portion draw-out hole 113.

The LED substrate fitting grooves 180a and 180b are formed on the inner circumferential surfaces of the left case 110a and the right case 110b at positions lower than the vane insertion holes 112 so that the LED substrate 150 can be laterally inserted desirable.

7 is an assembly flow chart for explaining the assembly process of the bulb-type LED lighting device 2 according to the present invention.

7A, the LED substrate 150 and the PCB substrate 130 are assembled using the bonding bundle 140, and the connection terminals 120 are fitted to both sides of the PCB substrate 130. Next, as shown in FIG.

Next, as shown in FIG. 7B, the illumination cap 170 is assembled to the left case 110a. At this time, the left wing portion 171 of the illumination cap 170 is fitted into the wing insertion hole 112 from the inside to the outside of the left case 110a.

At this time, when the wing insertion hole 112 is divided by the left case 110a and the right case 110b like the contact portion drawing hole 113, the left wing portion 171 is inserted into the wing insertion hole 112, So that it is difficult to place it horizontally temporarily and then the assembly process becomes very inconvenient. Therefore, as described above, it is preferable that the wing insert hole 112 is positioned so as not to be divided by the left case 110a and the right case 110b.

Of course, such assembly may be performed first in the right case 110b. Also, the steps in FIGS. 7A and 7B do not necessarily have to be performed in order, but may be reversed.

7C, the contact portion 125 of the connection terminal 120 is laterally inserted into the contact portion withdrawing hole 113 of the left case 110a so that the PCB substrate 130 and the LED substrate 150 are connected to each other And assembled to the left case 110a. At this time, the left end of the LED substrate 150 is caught in the LED substrate fitting groove 180a of the left case 110a.

Next, the right case 110b is assembled to the left case 110a, thereby completing the assembly of the LED lighting apparatus 2 according to the present invention as shown in Fig. 7D. At this time, the right wing portion 171 of the illumination cap 170 is fitted into the wing insertion hole 112 of the right case 110b from the inside to the outside, and the right end of the LED substrate 150 is connected to the right case 110b. And the contact portion 125 of the connection terminal 120 is sandwiched laterally in the contact portion drawing hole 113 of the right case 110b.

The left and right sides of the LED substrate 150 are fitted and fixed in the LED substrate fitting grooves 180b so that the LED substrate 150 rattles or sinks down even when the spherical LED lighting apparatus 2 according to the present invention is turned upside down The case does not occur. Therefore, unlike the conventional case in which the illumination cap 170 is pressed against the LED substrate 150, the illumination cap 170 can be installed not to touch the LED substrate 150 in the present invention. This means that the illumination cap 170 can be spaced away from the heat source.

8 is a view for explaining the installation structure of the bulb-type LED lighting device 2 according to the present invention. As shown in FIG. 8, the bulb-type LED lighting apparatus 2 according to the present invention is used by holding the handle 115 and inserting it into the socket 1a.

The present invention has the following advantages over the prior art.

First, since the left case 110a and the right case 110b are laterally coupled after the connection terminal 120 is inserted into the PCB 130, the connection terminal 120 can be easily assembled. In the conventional case, there is a drawback in that a skilled worker is required in a process of forcibly fitting the small connection terminal 20 into both sides of the inside of the illumination case 10, and a high concentration and time is required. However, Is solved.

In the process of assembling the left case 110a and the right case 110b in the lateral direction, both wings 171 of the illumination cap 170 are fitted and fixed to the wing insertion holes 112, There is no fear that the illumination cap 170 will come off after assembly even if it is not used. This is very useful when the bulb-type LED illumination device 2 is installed upside down, such as a ceiling of a vehicle. In addition, since no adhesive is required, disassembly and assembly can be performed reversibly.

Third, unlike the conventional case in which the connection terminal 20 is fitted from top to bottom, in the case of the present invention, the connection terminal 120 is fitted sideways in the process of lateral coupling of the left case 110a and the right case 110b Therefore, it is sufficient that the contact portion drawing-out hole 113 is formed so as to penetrate only the required portion without being formed long from the upper end of the illumination case 110 to the bottom. Therefore, the height h of the contact portion drawing-out hole 113 is lower than that of the conventional example, so that heat emission through the contact portion drawing-out hole 113 can be minimized.

In addition, since most of the heat is mainly emitted through the air vent 180 formed in the bottom of the lighting case 110, the front side of the bulb-type LED lighting device 2 where the heat is ultimately inserted into the socket 1a So that it is possible to obtain an effect that the heat near the head of the lighting is largely reduced when it is used, for example, in a vehicle interior lamp.
