Abstract

The purpose of the present invention is to provide an Edison bulb-type LED bulb that: can irradiate light over a wide range by providing multiple LED modules, which are light source units, in a bar configuration in a lamp housing; is easy to make compact by virtue of having power supply means provided inside a base portion; and has minimal loss of power supply efficiency (which occurs due to welding byproducts etc.) because the LED modules that are light sources are attached through ultrasonic welding to a power introduction means that supplies power.

Description

Edison Bulb Type LED Bulb

The present invention, the Edison bulb-type LED lamp, the LED module as a light source is configured as a chip on board (COB) type is located inside the lamp housing portion does not require a separate heat dissipation configuration and the power connection means connected to the LED module It is a Edison bulb type LED lamp that can be bonded by ultrasonic welding, which makes the bonding more solid and improves the efficiency of power supply because no by-products remain compared to conventional welding.

Modern luminaires have evolved from filament-based Edison bulbs to fluorescent lamps, three-wavelengths, halogen lamps, etc. In recent years, low-power, durable and relatively low heat LEDs are being applied to luminaires. This LED is relatively easy to apply the LED module has been easily applied to various types of bulbs. In this trend, the LED module is applied to the Edison bulb type bulb which uses the most traditional filament. Conventional technology having the same characteristics has been disclosed in Korean Patent Laid-Open No. 10-2012-0068657.

Conventional technology is similar in shape to Edison bulbs using conventional filaments, but the LED module serving as a light source is provided in one direction so that the irradiation range is small, and there is a configuration for power supply and a heat dissipation inside. There was a limitation in the LED module. That is, the conventional Edison bulb emits light in all directions of 360 degrees, so the irradiation range is limited compared to that of the existing Edison bulb. In addition, the addition of the LED module is possible only by using a flat LED module, which is impossible to add effectively.In addition, it is difficult to add additional light sources because the inside is provided with a configuration for power supply and heat dissipation.

Hereinafter, the Edison bulb-type LED bulb of the present invention as described above will be described in detail with reference to the accompanying drawings. The drawings introduced below are provided by way of example so that the spirit of the invention to those skilled in the art can fully convey. Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms. Also, like reference numerals denote like elements throughout the specification.

1 is a conventional Edison bulb embodiment, Figure 2 is an Edison bulb type LED bulb embodiment of the present invention, Figure 3 is a light source unit embodiment of the present invention, Figure 4 is a light source embodiment of the present invention.

As shown in Figure 2, the Edison bulb-type LED bulb of the present invention is a lamp housing 110, which is formed to be hollow inside the transparent or opaque material that can transmit light, on one side of the lamp housing 110 A base part 120 formed to be coupled to an external luminaire, a light source part 130 formed as at least one light source 131 in the lamp housing part, and a shape corresponding to an external luminaire outside the base part 120; External power connection means 141 is formed to be connected to an external power source, the power provided in the base portion 120 and connected to the external power connection means 141 to be available in the light source unit 130 Power supply means 142 for converting and rectifying, power introduction means 143 for supplying power supplied from the power supply means 142, the power introduction means 143 and the light source 131 of the light source unit 130 Between) The power supply unit 143 may include a power supply unit 140 including power connection means 144 for electrically connecting the power introduction means 143 and the light source 131.

The lamp housing 110 may be made of glass or acryl-based material, which may be transparent or opaque, and may use a material that may transmit light generated from the light source 131 to the outside.

At this time, the LED bulb of the present invention is preferably formed in a spherical shape similar to the conventional Edison bulb shown in FIG. Through this, the LED bulb of the present invention can be emitted in a wider range when the light source 131 is formed in the hollow inside the lamp housing 110 in the form similar to the filament of the conventional Edison bulb to emit light It has the advantage that the angle is wider.

3 shows an embodiment of the light source 131 arrangement of the LED bulb of the present invention. In this case, as shown in FIG. 4, a bar type LED module having a chip on board (COB) type is used as the light source 131. Therefore, the light source 131 has a structure capable of emitting light toward the front 180 degrees. By arranging the light sources 131 in parallel with diagonal lines, the emitted light can be more effectively controlled, thereby maximizing the irradiation angle. Through such a structure, it is possible to produce a customized LED bulb by adjusting and processing the arrangement of the light source 131 as needed. That is, it is possible to produce an LED bulb having an optimized irradiation angle by changing the arrangement of the light source 131 according to the intended use has the advantage that it is possible to produce an optimized LED bulb corresponding to the user's needs.

In addition, the power supply unit 142 of the power supply unit 140 is provided in a minimized form inside the base unit 120. In the past, it was common to have a structure in which a lighting device outside the light bulb had a separate conversion and rectification device for the light bulb. However, this structure had a disadvantage that the bulb used in the lighting device is limited depending on the stabilizer. However, the LED bulb of the present invention has an advantage that the power supply means 142 for converting and rectifying the base portion, which is a screw socket portion of the existing Edison bulb, can be maximized versatility because a separate device is not required. In addition, it was difficult to check when a failure occurs in the conventional stabilizer, but the LED bulb of the present invention can effectively respond to the failure by continuously replacing the power supply means 142 through the replacement of the bulb. At this time, the power supply means 142 is preferably formed of a switching mode power supply (SMPS). Through this, the AC power supplied from the external power source can be controlled intermittently at high frequency by using a high-speed power semiconductor, and stable DC power can be obtained through rectification and smoothing circuits.

In addition, the light source 131 is electrically connected to the power introduction means 143 of the power supply unit 140 through the power connection means 144. At this time, the light source 131 and the power connection means 144 are bonded by ultrasonic welding. An example thereof is shown in FIG. 5.

First, as shown in FIG. 4, the light source 131 and the power connection means 144 are welded using Wedge bonding. This enables more detailed welding to thin LED modules, and the size can be reduced compared to the wider type of modules required for conventional welding through such fine welding. It has the advantage of minimizing supply efficiency. Next, the power connection means 144 and the power introduction means 143 are bonded by using a general ultrasonic welding. This maximizes the joint area and enables more firm joints. At this time, the power connection means 144 is preferably formed of aluminum wire suitable for ultrasonic welding.

In addition, an inert gas may be injected into the hollow inside the lamp housing 110. This has the advantage that the light emitted from the light source 131 is amplified through the inert gas to increase the efficiency.
