Description

LED Module with Card Converters {LED MODULE INCLUDING CARD-TYPE CONVERTER}

The present invention relates to the manufacture of a card type converter. In more detail, the converter coupled to the LED lighting device can be separated into an AC module and a DC module in the form of a detachable card, and can be combined with the inner case part and the outer case part to facilitate construction and shorten working time. The incidence of safety accidents can be reduced.

Recently, lightings using LEDs (Light Emitting Diodes), which are semiconductor devices, have advantages of long product life and low electricity consumption.

LED is an optoelectronic device that has a junction structure of P-type and N-type semiconductors, and emits light of energy corresponding to the energy band gap of a semiconductor by combining electrons and holes when voltage is applied. Compared with a general gas discharge lamp, it is faster and consumes less power.

Lighting devices using such LEDs have been in the spotlight recently.

LED is a semiconductor device that emits light when power is applied, and most LED lighting devices are configured to install an LED module by installing LED elements at regular intervals on the LED substrate, and use the LED module as illumination.

1 is an exploded perspective view of a conventional LED lighting apparatus. More specifically, an exploded perspective view of the LED surface lighting device.

Conventional LED lighting device is composed of a heat sink (1), reflector (2), LED module (3), light guide plate (4), diffuser plate (5), top cover (6), converter (7) and frame (8). do. A module in which a plurality of LED elements are combined and emits light is referred to as an LED module 3. Each component is a well-known technology, and thus detailed description thereof will be omitted.

The converter 7 or ballast serves to convert AC to DC in the circuit. In the case of the converter 7, a failure occurs frequently in the LED surface lighting device due to the material characteristics. When the lifetime of the converter 7 expires, the entire LED surface illuminating device will be broken, so a replacement is necessary.

In this case, conventionally, since the converter 7 is generally installed inside the LED surface lighting apparatus, in order to replace the converter 7, the entire LED surface lighting apparatus must be separated and replaced and repaired. As a result, the work time is excessively excessive, and safety accidents frequently occur during the replacement process.

Figure 2 briefly describes the component structure of a conventional LED surface lighting apparatus. The converter 7 in the dashed line and the LED module 3 are combined in the LED surface illuminator, and the power supply P for supplying power to the LED surface illuminator is external.

The main cause of the failure of the LED module is the damage caused by the heat of the LED element and the failure of the converter or ballast.

Since the lifetime of the converter or ballast is shorter than the life of the LED, the entire LED lighting device must be replaced or repaired by removing the entire LED lighting device, resulting in excessive work time and a risk of a safety accident.

The inner case part 100 is provided with an inner case 110, a connector 120, a guide part 130, and a coupling part 140.

The inner case 110 is provided with one side open in a rectangular parallelepiped shape formed therein. Here, the open one side of the inner case 110 means a direction in which the outer case 200 is coupled.

Therefore, one side of the inner case 110 is open to accommodate the outer case 200 to be described later.

In addition, the other side of the inner case 110 is preferably a connector 120 is coupled. As shown in FIG. 4, the connector 120 includes an AC connector 121 to which the AC module 400 is connected and a DC connector 122 to which the DC module 500 is connected. Here, since the AC connector 121 and the DC connector 122 correspond to a well-known part as a connection mechanism for configuring an electric circuit by connecting an electric appliance and a cord, detailed description thereof will be omitted.

Therefore, when the AC module 400 and the DC module 500 are fastened through the outer case part 200, the other side of the inner case 110 is connected to the AC connector 121 and the DC connector 122 to connect the electric circuit. It can be configured (see Fig. 4).

As such, the coupling part 140 is symmetrical with respect to the virtual center line formed in the longitudinal direction at one side of the inner case 110 to be coupled to the outer case part 200 (see FIG. 3).

The coupling part 140 may be recessed in a cylindrical shape from one side of the inner case 110 to the inside to be coupled to the outer case part 200 by inserting a known coupling part such as a screw or bolt.

When the guide portion 130 is viewed from the front, the shape is trapezoidal, preferably, the length of the reference numeral 'd2' is longer than the length of the 'd1'.

Accordingly, when the outer case portion 200 is coupled along the guide portion 130, when viewed from the front, the outer case portion 200 slides from one side of the inner case 110 to the other side due to the trapezoidal cross section of the guide portion 130. When combined, the effect of lowering the possibility of the outer case part 200 leaving the guide part 130 is generated.

In addition, there is no need to use a lot of coupling parts for the combination of the inner case portion 100 and the outer case portion 200, there is no need to use a separate coupling tool, there is an advantage that the convenience of the operation is increased.

The outer case part 200 includes an outer case 210, a transformer 220, a protrusion 230, a through part 240, a groove part 250, a lamp 260, and a diagnosis part 270.

The outer case 210 has a first outer case 211 having a rectangular parallelepiped shape that can be inserted into a hollow portion of the inner case 110, and the inner case 110 at one side of the first outer case 211. The second outer case 212 is provided in a panel shape having a size of contact with one side of the.

Accordingly, the outer surface of the first outer case 211 is in contact with the inner surface of the inner case 110, and the side of the second outer case 212 facing the first outer case 211 is the inner case 110. It is coupled to abut one side.

A through part 240 is provided in the second outer case 212 on the same line as the coupling part 140 for coupling the inner case 110 and the outer case 210.

Protruding portion 230 is formed in a shape corresponding to the guide portion 130, it can be coupled to slide from one side to the other side along the guide portion 130. Since this has been described in detail, detailed description of the combination will be omitted to avoid duplication.

In addition, the center of the outer case 200 is preferably provided with a recess 250 is recessed.

The groove 250 is provided with two spaced predetermined intervals in the width direction, and is recessed in a rectangular shape.

Therefore, the AC module 400 and the DC module 500 to be described later may be coupled through the groove 250 to be detachable.

In detail, the conventional converter basically combines an AC converter circuit and a DC converter circuit on one circuit board. At this time, the AC converter circuit and the DC converter circuit can be separated, but conventionally, each circuit is coupled to one circuit board.

However, in the present invention, the AC converter circuit and the DC converter circuit are separated, and the AC module (including the circuit board) 400 to which the AC converter circuit is coupled and the DC module (including the circuit board) 500 to which the DC converter circuit is coupled are provided.
