Description

Lighting lamp using light emitting diodes {SECURITY LAMP USING LIGHT EMITTING DIODE}

The present invention relates to a lighting lamp such as indoor lighting or a security lamp installed outdoors, and more particularly, by installing a module substrate having a high brightness light emitting diode (LED) mounted on a bulb in a high vacuum state. The present invention relates to a light lamp using a light emitting diode that emits bright light with less power consumption when used for lighting or outdoor security light, and also blocks heat and moisture to extend the life of the light and maximize the reflection efficiency. .

In general, lighting systems such as roads less than 12m wide, or security lights installed on the sidewalks of parks or residential areas, which are frequently passed by vehicles, brighten dark streets to promote nighttime city functions such as promoting traffic safety at night and providing convenience for citizens. As such, the lighting system is equipped with a large amount of security lighting equipment in an area, and when it starts to darken, it is automatically flashed according to the surrounding environment and selectively turned off according to the activities of the citizens.

Examples of the lamp used for the security lamp include a halogen lamp, a mercury lamp, a metal halide lamp, a sodium lamp, and the like.

Power consumption of the halogen lamp, mercury lamp and metal halide lamp is different depending on the type of each lamp. For example, there is a lamp having a power consumption of 175W to 1.5KW. In addition, sodium lamps have considerably higher advantages than halogen lamps, mercury lamps, and metal halide lamps in terms of efficiency compared to power consumption.

Due to the high efficiency of such sodium lamps, the work of replacing halogen lamps, mercury lamps, and metal halide lamps that have already been used in recent years with sodium lamps is in progress.

However, there is a problem in that unnecessary power consumption is increased when using various types of lamps as security lamps, and in particular, the lamps are turned on by an integrated electronic ballast, and thus the electronic ballast becomes aging and performs unstable operation. Or there is a problem to replace the integrated electronic ballast and the lamp at the same time when the lamp reaches the end of its life.

Therefore, as a method for solving the problem of power consumption according to the use of the lamp and to simplify the extension of the lamp life and replacement of the lamp, it is known, for example, by Korean Utility Model Publication No. 1998-14446.

1 and 2 show one of the lamp structure using such an LED described in the Republic of Korea Utility Model Publication No. 1998-14446.

As shown in FIGS. 1 and 2, the lamp structure using the LED includes a reflector 30 in which a plurality of convex protrusions 31 are formed forward and the outer end side is bent inward in constructing a tunnel light or a street light. ) Is coupled to the inside of the lamp body 50 in which the circuit board 40 is built, and an LED fixing plate 21 having a plurality of high-brightness LEDs 20 attached to the front of the reflector 30 is provided. By bending inwardly, the light emitted from the high-brightness LED 20 is concentrated in the center to double the brightness, and the inner lens lens 10 in which a plurality of convex lens groups 11 are formed on both sides of the LED fixing plate 21 is convex. It is constructed by sealingly coupling the cover body 60 in which a plurality of convex protrusions 61 are formed on the inner surface thereof after the snow is installed.

The state of use of the lamp structure using a conventional LED made as described above will be described below.

When the operating power is applied to use the lamp using the LED as a tunnel lamp as shown in FIG. 1 or as a street lamp as shown in FIG. 2, a plurality of high brightness LEDs 20 installed in the lamp body 50 generate light. .

As described above, the light generated from the plurality of high-brightness LEDs 20 is concentrated to the upper center of the LED fixing plate 21, and the collected light is the convex lens group of the plurality of convex lenses 10 formed on both sides of the convex lens. After passing through (11), the brightness is further doubled, and is intensely emitted to the outside through the cover body 60 installed in front of the inner lens 10 and a plurality of convex protrusions 61 are formed on the inner surface.

In other words, the direct light is reflected back by the convex lens group 11 in which both sides are convex in the process of passing through the inner lens 10 installed in front of the LED fixing plate 21. In this case, the reflected light is installed at the rear of the LED fixing plate 21 and a plurality of convex protrusions 31 are formed on the surface thereof and hit the reflecting mirror 30 which is bent inwardly and is reflected back toward the inner lens 10. The side light generated by the plurality of high-brightness LEDs 20 is emitted through the cover body 60 in which a plurality of convex protrusions 61 are formed on the inner surface while being amplified directly through the inner case lens 10 without reflecting back.

In this way, by using the direct light and the side light emitted from the high-brightness LED 20 efficiently, it can be used as a security light to brighten the surroundings by emitting a light that is never behind the light emitted from the conventional halogen lamps, and also high brightness If a part of the LED 20 is broken, only the failed high-brightness LED can be replaced with a new one.

However, according to the lamp structure using the LED of the Republic of Korea Utility Model Publication No. 1998-14446 described above, the LED fixing plate 21 to which a plurality of light emitting diodes (LED) is fixed, the inner case convex lens 10 and both sides of the light, Reflectors 30 having a plurality of convex protrusions 31 formed on the surface for reflection, and a plurality of convex protrusions 61 in front of the circuit board 40 and the lamp body 50 for driving the light emitting diodes are provided. There is a difficulty in bending the reflector and the LED fixing plate inward to reflect the light and the complexity of the structure to be provided with the cover body 60 formed, thereby increasing the manufacturing cost of the security light, as well as productivity There is a disadvantage that is extremely degraded.

In addition, a plurality of light emitting diodes (LEDs), which are semiconductor elements which are very sensitive to moisture and heat, are not completely waterproof sealed to the lamp body 50, and the cover body 60 prevents rain or other insects from Because it is configured to protect only, in particular, when the wet weather lasts or in the rainy season, the above-described semiconductor device may malfunction or be damaged by moisture or water flowing into the lamp body, and also by the heat inside itself. It is pointed out that a problem that a semiconductor device is damaged often occurs.

Accordingly, it is desirable to provide an illumination lamp for indoor lighting or atmosphere production in addition to a security lamp in terms of the use, while providing a more efficient and stable illumination lamp in terms of reliability while healing the conventional problems as described above.

Accordingly, an object of the present invention is to provide a lamp using a light emitting diode to improve the lighting efficiency with less power consumption when used as a security lamp or indoor lighting, which is very simple in structure and waste of power. Characterized in that is minimized.

Another object of the present invention is to provide a lamp that protects the light emitting diode from heat and moisture to prolong its life. The lamp includes a module substrate in which a plurality of light emitting diodes are arranged and soldered in a high vacuum bulb. Nitrogen gas is injected into the bulb to block heat and moisture from the outside.

Another object of the present invention is to provide a lamp using a light emitting diode to improve the reflection efficiency of the lamp when used as a security light or a room lighting, which is at least 2/3 aluminum in the high vacuum transparent bulb. It is characterized by reflecting the light of the light emitting diode by depositing.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of a lamp using a light emitting diode according to the present invention in detail.

In addition, in each figure used for description, the same component may be attached | subjected, and may show the same number, and the overlapping description may be abbreviate | omitted.

FIG. 3 is a front view of a partially cutaway view of a lamp using a light emitting diode according to the present invention, and FIG. 4 is a side view of a partially cutaway lamp of FIG. 3.

As shown in FIG. 3 and FIG. 4, the lamp 100 using the light emitting diode according to the present embodiment has a module substrate 102 in which a plurality of high brightness light emitting diodes 102a are semi-permanently arranged in parallel.

The module substrate 102 is longitudinally disposed at a central portion in the substantially hemispherical bulb 101 made of hard glass, and the bulb 101 of the hard glass is formed at the first end by the molding 107 and the depression ( 101a) at the second end. In addition, the bulb 101 is in a high vacuum state, and nitrogen gas is introduced to block heat and moisture from the outside.

The base portion 105 of the conductor is fitted to the outer circumferential surface of the molding 107 and is bonded and fixed with an adhesive. In the base portion 105 of the conductor, two first and second lead lines 108 and 109 for supplying power are disposed to face each other.

One end of the first lead wire 108 is electrically soldered and connected to the surface of the base portion 105, and the other end is positioned in the bulb 101 through the molding 107 while keeping the airtight. In addition, one end of the second lead wire 105 is soldered and connected to the contact portion 106 attached to the bottom surface of the base portion 105, and the other end penetrates the molding 107 in the same manner as the first lead wire 108. 101). The contact portion 106 and the base portion 105 are not electrically shorted but are separated.

And, inside the bulb 101, the first and second support rods 103 and 104 of the conductor for supporting the module substrate 102 and supplying power are spaced apart from each other according to the size of the module substrate 102. Are placed opposite each other. The first supporting rod 103 is soldered and fixed to the copper plate of the module substrate 102, for example, the copper plate 102b on the plus side, and one end thereof is soldered and fixed to the first lead wire 108. In addition, the second support rod 104 is soldered and fixed to the negative copper plate 102c of the module substrate 102, and one end thereof is coupled to the second lead wire 109 and the other end thereof to the recessed portion 101a. .

In addition, the inner surface of the bulb 101 having a hemispherical shape made of hard glass is placed on the rear side of the module substrate 102 about 2/3 of the entire area of the bulb 101, and the aluminum is used as the reflective member 110. Is deposited. In addition, in order to drive the high brightness light emitting diode 102a, a positive voltage and a negative voltage of 5 to 12 volts (V) are required. The DC voltage of 5 to 12 volts (V) is a voltage obtained by rectifying the 220 V commercial AC power supply in a rectifier (not shown) after the voltage drop, and is applied to the base portion 105 and the contact portion 106 to be used. do.

The lighting lamp using the light emitting diode according to the present invention made as described above will be described in more detail with reference to FIGS. 3 and 4.

From the base portion 105 and the contact portion 106 of the lamp 100 using the light emitting diode according to the present invention, a DC voltage, for example, 5V or 12V of plus (+) and minus (-), is the first and second lead lines 108. 109).

The positive DC voltage through the base portion 105 and the first lead line 108 having the shape of a screw cap is connected to the positive side of the module substrate 102 soldered thereto through the first supporting rod 103 of the conductor. The negative side of the module substrate 102 supplied to the copper plate 102b and further connected to the copper plate 102b by a negative DC voltage through the contact portion 106 and the second lead line 109 is soldered thereto through the second supporting rod 104 of the conductor. It is supplied to the copper plate 102c.

When a DC voltage is applied to the positive side copper plate and the negative side copper plate of the module substrate 102, a plurality of high-brightness light emitting diodes 102a which are electrically parallel to the module substrate 102 and have a soldered lifetime are operated to emit light. Will diverge.

Light emitted from the high-brightness LED 102a transmits the transparent bulb 101 made of hard glass to brighten the surroundings, and reflects light such as aluminum deposited on the inner surface of the bulb 101 by approximately 2/3. By reflecting from the member 110 and penetrating the bulb 101, it is possible to brightly illuminate the surroundings where the lamp or security lamp is installed. Here, the number of the high brightness light emitting diodes 102a disposed on the module substrate 102 is not limited, but is increased or decreased depending on the use of security lights or indoor lighting or atmosphere. In addition, since the second support rod 104 is fixed to the recess 101a and fixed to the second lead line 109 and soldered to the module substrate 102, the module substrate 102 is irrelevant regardless of the increase or decrease of the high brightness light emitting diode 102a. ) Is stably supported in the bulb 101.

Subsequently, since nitrogen gas is injected into the bulb 101 in a high vacuum state, heat or moisture inside the bulb 101 is prevented when the LED lamp is used as a security lamp, thereby protecting the high brightness light emitting diode 102a. In addition, the lifespan is extended, and the reflection efficiency is improved by the reflection member 110.

And, Figure 5 is a longitudinal cross-sectional view showing a second embodiment provided for the description of the lamp using the light emitting diode according to the present invention.

In the second embodiment, as shown in FIG. 5, the molding 107 described above includes a base 200 that can be directly inserted into a socket instead of the base 105 having the screw cap shape in the first embodiment. By sticking to the outer circumferential surface of the sheet) and adhering and fixing it with an adhesive, the same effect and effect as in the first embodiment can be obtained.

On the other hand, as a comparative example, a number of light emitting diodes, which are conventional technology, that is, semiconductor elements which are very sensitive to moisture and heat, are not completely waterproof sealed to the lamp body, but are only protected from rain or other insects by the cover body. Unlike the complex structure of the present invention, the present invention combines a plurality of light emitting diodes in a high vacuum bulb with a first and second support rods to supply power, thereby providing a plurality of high brightness light emitting diodes that have a semi-permanent lifetime. It can be seen that the light is emitted from the light reflecting through the reflecting member to brighten the surroundings.

As a result, according to the present invention, when used as a security lamp or an indoor lighting lamp, the lighting efficiency can be improved with less power consumption, and internal heat and external moisture are prevented by the introduction of nitrogen gas. As the light emitting diode is protected, the lifespan is extended and the reflection efficiency is excellent.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.
