Description

Detachable vehicle light emitting diode and its module {DETACHABLE LIGHT EMITTING DIODE FOR VEHICLE AND MODULE THEREOF}

The present invention relates to a light emitting diode lamp and a light emitting diode module mounted in a vehicle light source assembly. Specifically, a light emitting diode lamp which allows the light emitting diode lamp to be detachably and elastically coupled to the terminals formed on the metal bar shaped bus bar of the light emitting diode module so that the light emitting diode lamp can be repeatedly mounted on the bus bar while being repeatedly replaced. And a light emitting diode module.

Light emitting diodes (LEDs) are semiconductor devices for generating light of various colors when a current is applied. The color of light generated by the light emitting diode is mainly determined by the chemical components constituting the semiconductor of the light emitting diode. These light emitting diodes have a number of advantages, such as long life, low power, excellent initial driving characteristics, high vibration resistance, and high tolerance for repetitive power interruptions compared to filament based light emitting devices.

Recently, light emitting diodes have been widely used in light source assemblies such as automotive indicators and stoplights in the form of modules. In particular, since the indicator and stop lamps based on the existing incandescent lamp occupy a lot of rear space, when the light emitting diode assembly is used as the indicator and / or stop lamp, the rear space can be efficiently utilized.

1 is an exploded perspective view of a light source assembly mounted on a rear of a typical vehicle. Referring to FIG. 1, a vehicle light source assembly 12, such as an indicator light and a stop light, includes a housing 14, one or more light emitting diode modules 10, and a back plate 16. The light emitting diode module 10 includes a plurality of light emitting diode lamps 18 electrically-mechanically connected in a band form. At this time, at least a part of the light source assembly 12 has a curved shape consistent with the shape of the rear of the vehicle.

Such a light emitting diode module 10 is shown in more detail as shown in FIG. 2. Referring to FIG. 2, each light emitting diode lamp 18 has a pair of leads 24 and 26 extending outwards in opposite directions. Among these leads 24 and 26, the first lead 24 (eg, the anode lead) is connected to the first bus bar 28 in the form of a metal rod, and the second lead 26 (eg, the cathode lead) is connected to the second bus bar ( 30) respectively.

In this manner, it is important that the LED module 10 used in the vehicle is designed so that each LED lamp 18 does not fall from the module even when subjected to shaking, impact, or the like. Therefore, the connecting portions 34 and 36 between the leads 24 and 26 and the buses 28 and 30 should be firmly formed, and it is necessary to facilitate the connection work easily and quickly.

To this end, a technique of connecting a lead to a bus bar at a connecting portion using a laser device is used. The laser beam is irradiated to the connecting part to instantly melt the corresponding part of the lead and the bus bar and join them to each other so that the connection work can be performed quickly.

However, this technique has the following disadvantages. First, it is very difficult to separate the LED lamps coupled to the metal frame again. Therefore, when any one LED lamp is broken, the entire LED module needs to be replaced. Secondly, this technique is expensive because laser devices are expensive.

Another method is to punch the corresponding portions of the leads and busbars and connect them to each other. As shown in cross section in FIG. 3, the button lock connection part 34 is formed through a clinching operation in which the lead 18 and the bus bar 28 are pressed up and down to engage each other. . This technique is disclosed in US Pat. No. 5,404,282. In addition, the connection portion 34 may be further pressed on the side to increase the bonding force.

However, there is a risk that the connection obtained by the technique is loosened by external force after coupling. In addition, if any one of the LED lamps fails or needs to be replaced, the clinching operation cannot be performed again and the lead must be coupled to the busbar through another technique such as laser welding described above. That is, it can be seen that the clinching technique can be used only once.

4 is a perspective view of a light emitting diode module according to a first embodiment of the present invention. Referring to FIG. 4, the LED module 100 of the present invention includes a plurality of LED lamps 102 and a bus bar 130 in the form of a pair of metal rods on which the lamps 102 are mounted.

Each light emitting diode lamp 102 is made of an insulator and extends downward from the body 104 and the body 104 made of a light emitting diode chip (not shown), a lens 106 made of a transparent body on the top of the body 104. It has a pair of leads 108 and 110. Each lead 108, 110 is equipped with an elastic socket 112, 114, respectively.

Each bus bar 130 includes a strip 132 having a constant width and a plurality of terminals 134 having a predetermined length protruding thereon, and the number of the terminals 134 is light emission required for the LED module 100. It depends on the number of diode lamps 102.

Since these elastic sockets 112 and 114 have the same shape, only the socket 114 of the right side will be described in the drawings in detail. With reference to FIG. 4, which precedes FIG. 5, the socket 114 is a back plate 116 extending integrally with the lid 110, and a back plate (116) drawing a circular arc of a predetermined curve from both sides of the back plate 116. A pair of hooks 118 folded toward the vertical centerline of 116. That is, each hook 118 is bent while the fixed end 118A is connected to the back plate 116 along the dashed line (Lb) and arced toward the free end 118B, the free end 118B is the back plate 118 The back plate 118 is in contact with (or at the center line) a position adjacent to the vertical center line.

The sockets 112 and 114 having such hooks 118 can be formed by various processes. For example, a sheet metal having a predetermined strength and thickness and a required shape can be formed by folding a sheet metal along a dashed line Lb using a press or the like. It can form by bending in a curve. At this time, the arc shape is determined according to the material, the thickness of the socket 114 and the elasticity required to firmly grip the terminal 134 of the bus bar 130.

On the other hand, the socket is formed separately from the leads (108, 110) can be coupled to the leads (108, 110) by suitable means such as welding, rivet coupling, screw coupling.

In addition, the socket is made of a metal, preferably a copper alloy, which can have good electrical conductivity while having a predetermined strength, whether formed integrally or separately from the lead.

Terminals 134 formed on each bus bar 130 are integrally formed with the same thickness as bus bar 130 in this embodiment. That is, the long metal bar is cut into a sawtooth shape to form a bus bar 130 having a strip 132 and a terminal 134.

Alternatively, a plurality of terminals may be attached to the strip-shaped bus bar by welding, riveting, screwing, or the like.

Hereinafter, a process in which the lamp socket 114 is coupled to the bus bar terminal 134 in the LED lamp of the present embodiment will be described with reference to FIGS. 6 to 8.

First, the lamp with the lamp socket 114 is moved toward the bus terminal 134 along arrow A (FIG. 6).

When the lower end of the hook 118 of the socket 114 is in contact with the bus terminal 134, the hook 118 is opened by the force of continuing to press the lamp along the arrow (A) to receive the terminal 134. Even at this time, the hook 118 keeps the required elasticity, so that the hooked terminal 134 is strongly gripped (FIG. 7).

Then, when the lamp is pressed further, the hook 118 completely receives the terminal 134 so that the coupling between the hook 118 and the terminal 134 is completed. As a result, the hook 118 strongly grips the terminal 134 by its own elastic force, and the lamp is stably mounted to the bus bar 130 by the gripping force of the socket 114 to receive electricity therefrom (Fig. 8).

Hereinafter, a modification of the socket will be described with reference to FIGS. 9 and 10. First, as shown in FIG. 9, the socket 214 is formed integrally with the lead 210 of the light emitting diode lamp, and the socket 214 is a back plate 216 extending integrally with the lead 210 and the back plate. A pair of hooks 218 folded toward the vertical centerline of the backplate 216 while drawing arcs of predetermined curve from both sides of 216. That is, each hook 218 is bent while the fixed end 218A is connected to the back plate 216 along the dashed line Lb and arced toward the free end 218B, and the free end 218B is the back plate 218. At the position adjacent to the vertical center line (or at the center line), the back plate 218 abuts with the necessary elasticity.

At this time, the hook 218 is raised from the fixed end 218A to the free end 218B while drawing a curved line 218C (or straight line), so that the socket 218 is connected to the terminal 134 of the bus bar 130. When engaged, both top ends of the terminals 134 in the position shown in FIG. 10 are located below the curve 218C of the hook 218 in part B of FIG. Thus, the elasticity of the hook 218 at the initial stage of the joining operation does not obstruct the insertion of the terminal 134, thereby facilitating the joining operation.

Hereinafter, a modification of the LED lamp of the present invention will be described with reference to FIG. 11. As shown in FIG. 11, the LED lamp 302 is a view except that the pair of leads 308, 310 extend laterally from the lower side of the LED body 304 laterally and refracted downward.

It is also possible to modify the sockets 442 and 444 of the present embodiment into the shape of the socket 214 shown in FIGS. 9 and 10.

That is, according to the LED module 400 according to the second embodiment, the sockets 442 and 444 of the bus bar 430 supply electricity while the LED lamp 402 is detachably mounted.

Hereinafter, a modification of the bus bar of the light emitting diode module according to the second embodiment of the present invention will be described with reference to FIGS. 14 to 16. First, as shown in FIGS. 14 and 15, each bus bar 530 is integrally formed with a strip of metal rods 532, a plurality of terminals 534 protruding from the strip 532, and respective terminals. Formed elastic sockets 542 and 544. The number of these terminals 534 and elastic sockets 542 and 544 is equal to the number of light emitting diode lamps 402 required for the light emitting diode module 400.

Since these elastic sockets 442 and 444 have the same shape, only the socket 444 on the right side of the drawing will be described in detail.

Each resilient socket 542 or 544 is in contact with the terminal 534 at the top of the terminal 534 in the opposite direction to the terminal 534 and extends in a circular arc shape along the required curve with the back plate 546 extending downward. 546 has a generally S-shaped hook 548 that extends upwardly back to the bottom of the 546. The hook 548 has a fixed end 548A integrally connected to the bottom of the back plate 546 and bent while drawing an arc toward the top of the back plate 546 to form a pressing portion 548B that presses the back plate 546 to the required pressure. do. The free end 548B of the hook 548 extends upwardly from the pressing portion 548B away from the back plate 546 to form a free end 548C having a predetermined distance G from the back plate 546.

Referring to FIG. 16, when one lead 510 of the LED lamp 502 is inserted into the socket 544, the free end 548C is spaced apart from the back plate 546 by a gap G. 510 is easily inserted. However, once the lead 510 is fully inserted and coupled, the hook 548 grips the lead 510 strongly by elastic force, so that the lead 510 does not easily fall out due to shaking, external impact, and the like. 502 is firmly mounted to bus 530.

Meanwhile, the sockets 542 and 544 may be integrally formed with or separately from the terminal 534 and may be combined with the terminal 534 by appropriate means such as welding, riveting, screwing, or the like.

As another method, the hooks 542 and 544 may be installed in the lead of the LED lamp and only the terminals may be formed on the bus bar as shown in FIG. 4 or 12.
