Description

LED Lighting Module

The present invention relates to a light emitting diode lighting module, and more particularly, to form a small LED lighting module using a light emitting diode (LED) having a low heat generation and low power consumption as a light source, and using them, various lighting fixtures (for example, stairs). Lighting, floodlight, security light, landscape lighting, house or barn or factory lighting, living room lighting, signage indirect lighting and downlight etc.) can be easily manufactured and used. Molded using a magnesium (Mg) alloy, a light metal series alloy having high properties, but is formed in a streamlined column shape rather than a thin film form so that air can flow in all directions through die casting. The converter housing enclosure, which supplies power to the diode, is injected with conductive / polymer heat-resistant resin. The multi-purpose LED lighting module invented to be able to significantly improve the heat dissipation function of the lighting fixtures itself by attaching and detachably fixed to the upper surface of the heat sink, and to reduce the weight and size of the lighting fixtures itself. will be.

In general, a conventional security lamp or street lamp is mainly used by mercury lamp or sodium lamp as a light source to illuminate so that the energy consumption is high compared to the brightness and the life is short. It became necessary.

In particular, since the mercury gas is used, the above-mentioned materials have a problem of causing environmental pollution during disposal.

Therefore, recently, a light lamp using a light emitting diode (LED) with low power consumption and long lifespan has been developed and released.

At this time, the light emitting diode (LED) generates a small number of carriers (electrons or holes) injected using a PN junction structure of a semiconductor having advantages such as fast response speed, low power consumption, and long life. It is used to emit light by recombination, and consumes about 1/10 of the power consumption of the conventional incandescent light bulb, which has the advantage of greatly reducing the electric energy.

In particular, in areas where high power is required, such as traffic lights, security lights, street lamps, floodlights, landscape lights, and house or livestock lamps, when sodium or mercury lamps, which are frequently used in these lighting fixtures, are replaced with light emitting diodes, The power savings effect is very large.

By the way, the conventional lighting device using a light emitting diode has a difficulty in solving the heat dissipation problem, mainly using a low brightness light emitting diode. In other words, when a high brightness LED is used, a considerable amount of heat is generated. If the airing function is poor, this heat causes damage to the peripheral device, and the life of the LED is also shortened rapidly. I can't have a problem.

As described above, a light emitting device using a light emitting diode, for example, a light emitting diode type security lamp or a street lamp, has a simple lighting circuit, unlike an ordinary fluorescent lamp or a street lamp, and does not require an inverter circuit and an iron ballast, and consumes power. Its low cost and long lifespan have the advantage of low maintenance and repair costs.

However, disadvantages of such light emitting diode type security lamps, street lamps, floodlights, landscape lightings, house or livestock lightings, signage indirect lightings, and downlights are aspects of deterioration and failure due to thermal stress.

The higher the current flowing through the plurality of light emitting diodes in order to operate the light emitting diodes, the more heat is generated, which leads to failure and deterioration of characteristics.

For example, a printed circuit board (PCB) such as a light emitting diode security light or a street lamp or floodlight, a landscape lighting, or a house or livestock lamp, a signboard indirect light, a down light, or a living room light may have a plurality of LEDs on a PCB. A control circuit for controlling the blinking and a power circuit for supplying power from the outside to each LED are implemented, and the control board causes malfunction or failure due to thermal stress caused by heat generated in the plurality of LEDs.

Therefore, in the conventional light emitting diode-type security light or street light, floodlight, landscape lighting, house or livestock lighting, signboard indirect lighting and down light, heat sinks such as heat sinks or slugs using metal materials having excellent thermal conductivity In many cases, the thermal stress caused by the light emission of the LED is to be eliminated, but the thickness and volume of the heat sink are increased to satisfy the heat dissipation efficiency required due to the limitations of the metal materials constituting the heat sink. The size and weight of the luminaire will increase.

In addition, in the case of a conventional light emitting diode lighting module or street light fixture, it is difficult to install a cooling device for efficient heat dissipation because it can block moisture from the outside only when it is kept closed due to its characteristics. Various foreign matters, including water and moisture, may enter from the outside of street lamps, floodlights, landscape lightings, and house or livestock lighting.

On the other hand, when die-casting the heat sink used in the light emitting diode lighting module with aluminum, its thickness, volume, and volume are so thick that the production cost of the product is increased, and there is a problem that it is impossible to reduce the weight.

In addition, in the case of replacing the conventional discharge lamp security lamp and floodlight with a light emitting diode type security lamp and floodlight, etc., the light emitting diode type security light and floodlight etc. Since there is not enough space to embed the heat dissipation mechanism can not be used as it is, there is also a problem that wastes unnecessary resources.

In addition, although the aluminum extrusion or die-casting structure of the conventional heat dissipation structure is somewhat superior in thermal conductivity, heat dissipation performance is drastically deteriorated in a sealed place.

For this reason, despite the heat dissipation structure that is rarely employed in notebooks and PCs in recent years, most heat dissipation configurations of LED lighting are composed of aluminum die casting or extrusion, but the overall volume is increased and the weight is increased.

In addition, the heat spreader of the conventional heat spreader (aka non-powered heat pump) principle is excellent in performance but limited in life, expensive and bulky, but in recent years it has been applied to expensive products such as notebooks and some LED lights, but In the case of appliances, the price becomes too expensive.

In addition, the heat dissipation structure, which is provided as a structure in which a conventional aluminum thin film sheet is laminated after pressing and bundled into a bundle, has a heat conduction portion to some extent and improves heat spreading performance. As a result, the air space in the narrow space between the thin plates has a problem of causing heat retention, and is also a heat dissipation method which is not recommended especially in a place where a lot of fine dust or dust is present.

On the other hand, the LED lighting module is used to produce various lighting fixtures such as staircase lighting, floodlight, security lamp, landscape lighting, house or barn or factory lighting, living room lighting, signboard indirect lighting, and downlight. In some cases, it is necessary to directly install a power supply converter directly on the module.In some cases, a large current limiter or color controller and a power supply converter are manufactured separately to connect power and signal lines to several lighting modules. You may have to.

However, in the case of directly installing a power supply converter alone in each of the above two lighting modules, it is conventionally formed in a housing molded of a general synthetic resin material having a very low thermal diffusion coefficient and thermal conductivity. Not only can't dissipate heat generated from the power supply converter itself installed in the lighting module, but also heat generated from the light emitting diode is radiated only through the heat sink, so the power supply that composes the light-emitting diode lighting module with built-in converter for power supply There is a problem that the lifetime of the light emitting diode including the converter for short.

The present invention has been devised to solve such a conventional problem, using a high-brightness light emitting diode (LED) as a light source with low illumination and low power consumption as a light source, the radiator is made of air flow in all directions The thermal diffusivity is approximately 1.7 times higher than that of aluminum, and the specific gravity is about 35% lower, and it is formed through die casting using a magnesium alloy, which is a light metal alloy having light characteristics. By using them, you can easily manufacture and use various lighting fixtures such as staircase lighting, floodlight, security lamp, landscape lighting, house or barn or factory lighting, living room lamp, indirect lighting and downlight, etc. The heat dissipation function of the module itself can be greatly improved, and The overall volume and volume of each LED lighting module can be greatly reduced, which enables to reduce the weight and size, and significantly reduce the production cost of the product. In particular, it is possible to use relatively high-power lighting fixtures such as floodlights and security lamps. In the production of modules, only the required number of LED lighting modules can be installed inside the reflector or case in the state of using existing props, reflector or case as it is, thereby greatly reducing the production cost and installation cost of the product. It is an object of the present invention to provide a light emitting diode lighting module that can reduce as well as prevent unnecessary resource waste.

Another object of the present invention, in the case of the LED lighting module having a power supply converter integrally installed without detaching the case, such that the enclosure in which the power supply converter is built directly on the upper surface of the heat sink. The heat generated from the power supply converter installed inside the enclosure by injection molding the enclosure with a conductive / polymer heat-dissipating resin material containing carbon nanotubes (CNT) having excellent thermal conductivity rather than general synthetic resin. Not only can the heat dissipate smoothly, but also some of the remaining heat of the light emitting diodes that are radiated through the radiator can also be radiated through the enclosure to provide a light emitting diode lighting module that can further reduce the weight and size of the LED lighting module itself. .

Another object of the present invention is to use the elastic fixtures in each LED lighting module in the case of a high-power lighting fixture that requires several LED lighting modules, such as floodlights or security lights, house or barn or factory lighting and living room lights, etc. Spiral sockets on enclosures, light projections, or diffusers, if it is necessary to easily fix them to the module mounting plate, and when one LED lighting module needs to be installed in the form of a bulb, such as staircase lighting, landscape lighting, signage indirect lighting, and downlights.

As such, when the heat sink 3 is formed of a magnesium alloy or a light metal series alloy including beryllium and titanium, duralumin, and a carbon-aluminum composite material, in particular, a magnesium alloy is formed, the density and specific heat of the heat sink 3 are respectively increased. 1.8 ± 0.3 [g / cm 3] and 1.02-1.05 [J / gK], so the density and specific heat are smaller than those of aluminum having 2.7 [g / cm 3] and 0.9 [J / gK], respectively, and the thermal diffusion coefficient is 0.84. Unlike aluminum, which is [cm2 / sec], it is 1.3-1.4 [cm2 / sec] high and 60-90 [W / mK] lower than that of aluminum having 220-240 [W / mK]. When the heat sink 3 is formed from a magnesium alloy, which is one of the light metal series alloys, the heat dissipation performance of the hot electrons is higher than that of the heat sink formed of aluminum. It can be.

However, the thermal conductivity, a factor that affects heat dissipation performance, is 60-90 [W / mK] lower than that of pure aluminum with 220-240 [W / mK] and aluminum alloy with 100-160 [W / mK]. The structure of the heat dissipation structure of the heat radiator molded with the characteristic magnesium has the cross-sectional area of the heat conduction part of the heat dissipation action based on aluminum and aluminum alloys, which is not in the form of a thin plate or a fine fin, as in the case of aluminum or aluminum alloy. It is highly preferable to design the column shape wider than about 1.5 to 2.5, and in the present invention, the actual technical contents thereof are shown in the drawings by the shapes (3a and 3d).

In addition, in the present invention, when heat-casting the heat sink 3 into a magnesium alloy, such as a light metal alloy, the heat sink 3 as shown in FIGS. 1B and 2B as necessary. Since the heat dissipation surface area of the heat dissipating body 3 can be increased by further protruding several heat dissipating protrusions 3b on the outer circumferential surface of the streamlined heat dissipating rods 3a protrudingly formed on the upper surface of the heat dissipating body 3a, The volume of the sieve 3 itself can be reduced, which is more advantageous for miniaturization of the LED lighting module.

In addition, the waterproof ring 4 commonly used in the two embodiments of the present invention is formed of rubber or silicon, and is formed in the waterproof ring insertion groove 1b formed on the rear surface of the light transmitting or diffusing plate 1. In the installed state to maintain the air tightness of the gap formed between the back of the light transmitting or diffuser plate 1 and the heat sink 3 to prevent the inflow of moisture, including moisture from the outside, and various foreign matters It will perform the function.

In addition, in an embodiment of the present invention, the LED lighting module itself is formed of only the light transmitting or diffusing plate 1 and the LED substrate 2, the heat sink 3 and the waterproof ring 4, and the LED substrate 2 Power and current control required for driving the LED 2a installed in the 1) may be controlled by a current limiter or a color controller and a power supply converter 5a separately manufactured from the LED lighting module. .

At this time, the current limiter or the color controller and the power supply converter 5a limit the current flowing through the LED 2a installed in the LED substrate 2 or control the color, as well as to drive the LED 2a. It performs the function of supplying the necessary power voltage.

Such a current limiter or a color controller and a power supply converter 5a may be applied to a lighting fixture such as a staircase lighting or a signage indirect lighting and a downlight where the LED lighting module itself is used as a single lighting fixture, as shown in FIG. 9. It is more preferable to apply to lighting fixtures such as floodlights, security lamps, landscape lighting, house or barn or factory lightings, in which a plurality of LED lighting modules are integrally installed.

On the other hand, unlike the embodiment of the present invention in which the current limiter or color controller and the power supply converter 5a is applied, the heat dissipation enclosure used in another embodiment in which the power supply converter 5b is directly installed in the LED lighting module itself. (6) is formed by injection molding of a conductive / polymer heat-dissipating resin material to have a rectangular housing shape provided with a lid 61 and detachably fixed to the upper surface of the heat dissipator 3 through a screw (9) And heats some residual heat of the LED 2a transmitted through the heat sink 3, including heat generated by the power supply converter 5b stored therein.

In addition, the power supply converter 5b provided in the LED lighting module itself supplies a power supply voltage for driving the LED 2a installed in the LED substrate 2 in the state of being housed in the heat dissipation enclosure 6. Will be performed.

In this case, as a material for injection molding the heat dissipating enclosure 6 and the lid 61, a conductive / polymer heat dissipating resin material containing carbon nanotubes (CNT) was used, and the density of the carbon nanotubes (CNT) was used. And specific heat have 1.4 ± 0.2 [g / cm3] and 1.1 ± 0.4 [J / gK], respectively, so that density and specific heat are smaller than aluminum having 2.7 [g / cm3] and 0.9 [J / gK], respectively. The diffusion coefficient is 0.75-0.8 [cm 2 / sec], unlike the aluminum having 0.84 [cm 2 / sec], and thus the air emission performance of the hot electrons is increased even with a smaller surface area and volume than the heat-dissipating enclosure 6 formed of aluminum. When the heat dissipation action portion is provided by the conductive / polymeric heat dissipation resin material containing carbon nanotubes (CNT), it is possible to contribute to weight reduction and miniaturization and cost reduction in processing and manufacturing than those provided by aluminum plate or steel plate.

In addition, in the present invention, when the heat-dissipating enclosure 6 is injection molded into a conductive / polymer heat-dissipating resin material containing carbon nanotubes (CNT), the heat dissipation type as shown in Figs. By further protruding the heat dissipation protrusions 6a for increasing the heat dissipation surface area at predetermined intervals on the front and rear surfaces of the enclosure 6, the heat dissipation surface area of the heat dissipation enclosure 6 can be further increased under the same heat dissipation conditions. Since the volume of the heat dissipation enclosure 6 itself can be reduced, miniaturization and light weight of the LED lighting module can be expected more.

Compare the thermal diffusion coefficient and material average properties such as thermal conductivity, density, melting temperature and specific heat for the conductive / polymer heat-dissipating resin containing magnesium alloy and carbon nanotube (CNT) compared to the aluminum and aluminum alloy Is as follows.

Here, thermal conductivity refers to a phenomenon in which heat is transferred from a high temperature portion to a low temperature portion which is in contact with it without accompanying a movement of a substance, and a heat transfer rate of an inside of an object by heat conduction is a temperature gradient (unit length) within the material. Sugar temperature difference), but there is a big difference depending on the type of material.

In addition, in the numerical value of the average characteristic of each material shown in the above chart, the degree of influence on the heat dissipation action and heat dissipation performance is described. The higher the heat spread coefficient is, the better the thermal dissipation surface area can be reduced; Higher thermal conductivity is also better, which provides the advantage of reducing the cross-sectional area that serves as thermal contact and thermal electron transfer, while lower density and specific heat are better, which is the surface area of the heat dissipation structure (i.e. heat sink and heat dissipation enclosure). It offers the advantage of reducing volume weight.

In addition, briefly introducing the materials shown in the above chart, "Conductive / Polymer Heat Dissipating Resin Containing Carbon Nanotubes" is a leader in commercialization of DuPont in the US, Nexatec Co., Ltd. of Japan, etc. And Acol Green Co., Ltd. have been developed and commercialized, the material is in the spotlight as a new material field. "Magnesium alloy" is mainly used in automobiles, bicycles and aerospace, but has been applied to various heat dissipation structures that need to be lowered due to low price due to the development of alloy improvement technology, molding processing technology and surface treatment technology. In the LED lighting field, the application of the thermal conductivity is insignificant due to the low problem.

"Aluminum" and "aluminum alloy" are very familiar heat dissipating materials, so the introduction is omitted. However, aluminum alloy has the advantage of being able to be processed in various forms compared to pure aluminum, while the specific heat [J / gK] is very large. The disadvantage is that diffusion (releasing heat into the atmosphere) is low, i.e., volume, volume and weight increase.

"Carbon-Aluminum Composite" is developed by American screw and Japan's AM Technology Co., Ltd., and is a composite material made by dissolving aluminum into carbon (carbon) mass. Although it is only used for high-end products, it is also expected that the price of the company will be greatly reduced as POSCO, Taiwan, and China's minority companies are in the stage of commercialization and commercialization.

For example, heat transfers very quickly in electrical conductors such as copper and iron, but slower in electrically insulating materials such as sulfur and plastics. Liquids and gases are also very late compared to solids. This is because the mechanism of heat conduction differs for each material, and this is represented numerically by passing a width of 1 cm2 of the layer within 1 second when a temperature difference of 1 ° C. is placed on both sides of a layer of material 1 cm thick. The amount of heat used is called the thermal conductivity of the material.

In general, the value varies slightly depending on the temperature, and may be regarded as a material constant having a nearly fixed value according to the type of material. In addition, there is a proportional relationship between the thermal and electrical conductivity of metals, and it was discovered by GH Bidemann and R. Franz in 1853 that both ratios at the same temperature had a constant value regardless of the type of metal. This is called the Bidemann-Franz's law.

As such, the thermal conduction in the metal occurs because free electrons carry heat from the high temperature portion to the low temperature portion in the form of kinetic energy, which causes a high thermal conductivity of the metal and a correlation between the thermal conductivity and the electrical conductivity. It is known that the higher the temperature, the lower the thermal conductivity is because the movement of free electrons is disturbed by the thermal vibration of the crystal lattice. On the other hand, in the case of dielectrics (insulators) that do not have the same free electrons, the vibration of atoms and molecules generated in a part of them by heat has a kind of wave characteristic, which is reflected from the surface to create standing waves, and the energy of the standing waves is uniformly internal energy. Height transfers heat by the principle of action.

Therefore, in the present invention, the heat dissipation structure design of the heat dissipation element 3, which is a structure that performs heat dissipation, is adopted to adopt a magnesium alloy having a relatively low thermal conductivity, a somewhat high thermal diffusivity, and the like, in order to achieve the purpose of weight reduction and miniaturization. Therefore, in order to increase the thermal conductivity, the cross-sectional area of the heat transfer path is increased by 40 to 60 [%] compared to that of the aluminum alloy, and since the thermal diffusivity is good, the surface area is reduced to about 30 to 50 [%] compared to the aluminum heat dissipation structure. In order to increase the ventilation, it is preferable to take a streamlined column shape capable of inflow and outflow of air from all sides of 360 [°], and to provide a structure in which the entire heat dissipating part is exposed to the outside in the entire structure of the module.

On the other hand, when the lid 61 is fixed to the upper surface opening of the heat dissipation enclosure 6 simply by using a few screws 9, moisture or various foreign matters are introduced from the outside through these gaps, thereby providing a power supply converter ( There is a risk of disturbing the driving of 5b).

Therefore, in the present invention, by further installing a waterproof packing 7 between the upper periphery of the upper opening of the heat dissipation enclosure 6 and the bottom of the lid 61, various foreign substances including moisture from the outside to the inside of the heat dissipation enclosure 6; It was to prevent the inflow.

In addition, in the present invention, both sides of the bottom surface of the lid body 61 of the heat dissipation enclosure 6 are provided with substrate guide grooves 61b for engaging both sides of the power supply converter 5b so that the heat dissipation enclosure 6 is provided. By further providing a side plate 61a inserted into the inside, the power supply converter 5b itself is stably fixed to the inside of the heat dissipation enclosure 6.

At this time, the components of the power supply converter 5b housed in the heat dissipation enclosure 6 in the state of being fixedly installed on the lid 61 have a form installed on the front side of the substrate, and thus the front part of the substrate and the heat dissipation enclosure. A sufficient space portion is formed between the inner wall of (6), but the space portion between the soldering portion, which is the rear side of the substrate, and the inner wall of the heat dissipating enclosure 6, is narrowly formed so that the soldered portion and the heat dissipating enclosure 6 may be electrically contacted and electrically shorted. In addition to the concern, there is a fear that heat dissipation to the soldered portion may not be smooth.

Therefore, in the present invention, an insulating shielding film 61c is further formed on the rear surface of both side plates 61a protruding from the lid 61 of the heat dissipation-type enclosure 6 to provide insulation between the soldered portion and the heat dissipation-containing enclosure 6. That is, it was possible to completely block the occurrence of a short circuit between the soldered portion of the power supply converter (5b) and the heat dissipation enclosure (6).

In addition, in the present invention, a pair or two in order to install a connector coupling power supply terminal 62 for supplying AC power to the power supply converter (5b) on the lid 61 of the heat dissipation enclosure (6) A pair of power supply terminal mounting holes 61d was formed.

At this time, when there is a pair of power supply terminal installation holes 61d formed on the lid 61 of the heat dissipation enclosure 6, as shown in FIG. 8, an AC power supply line and a jump line are integrally provided. In order to jump AC power to the LED lighting modules adjacent to each other outside the heat dissipation enclosure 6 of the LED lighting module, a power supply terminal 62 for connector coupling having an “I” shape was installed.

However, in the case of two pairs of power supply terminal mounting holes 61d formed on the lid 61 of the heat dissipation enclosure 6, adjacent LED lighting modules as shown in FIGS. In order to jump the AC power supply line in each pair, the power supply terminal 62 for coupling the connector bent and formed into a "c" shape is installed in each pair, so that each LED lighting module is installed in a lighting device having several LED lighting modules. The inconvenience caused by supplying AC voltage can be eliminated.

On the other hand, in the present invention, the guide groove (3c) is formed on the upper surface of the two streamlined heat-dissipating rod (3b) in a position opposite to each other on one side centerline of the streamlined heat-dissipating rod (3b) of the heat dissipator (3), In addition, on one side of the bottom of the heat dissipation enclosure 6, the guide rod 6b, which is fitted to the guide groove 3c of the streamlined heat dissipation rod 3b, was installed to protrude on both sides.

Therefore, when the heat dissipation enclosure 6 is placed on the upper surface of the heat dissipation body 3 and fixedly installed using the screw 9, the guide rod of the heat dissipation enclosure 6 is guided to the guide groove 3c of the streamlined heat dissipation rod 3b. Since the 6b is inserted and caught, the misalignment of the heat dissipation enclosure 6 can be prevented and the rotation of the heat dissipation enclosure 6 can be completely prevented when the heat dissipation enclosure 6 is fixed. It will be easier and more complete.

In addition, according to the present invention, a heat dissipation cum wire passing rod 3d itself protrudingly formed in the center of the heat dissipation body 3 is formed in a rectangular shape, and a heat dissipation cum wire passing through the bottom surface of the heat dissipation enclosure 6 is provided. The heat dissipation and electric wire having a flat cross section having a rectangular shape when a rod coupling groove 6c is formed and the heat dissipation enclosure 6 is placed on the top surface of the heat dissipation body 3 and fixedly installed using a screw 9. Part of the upper end of the passing rod (3d) is inserted into the heat dissipation and wire through-rod coupling groove (6c) of the heat dissipation enclosure (6), thereby preventing the misalignment of the heat dissipation enclosure (6) as well as fixing the heat dissipation enclosure (6). It is completely prevented from being rotated on the upper surface of the heat dissipation body 3, so that the assembly of the heat dissipation enclosure 6 can be made more simply and completely.

In addition, in the present invention, when the LED lighting module itself is to be used as a lighting fixture that can be screwed into the socket, such as a general bulb, a general bulb as shown in Figure 12 in the center of the upper surface of the lid body 61 of the heat dissipation enclosure (6) It is installed in the heat dissipating enclosure (6) through the spiral socket coupler (11) by fixedly installing the same spiral socket coupler (11) installed at the same time using an adhesive having both insulating and adhesive functions. Not only can supply AC voltage to power supply converter 5b smoothly, but also the LED lighting module itself is screwed into the socket like a general bulb, so that it is a staircase lamp, indirect lamp, and down light widely used as a single light fixture. Can be used as a light fixture for lighting fixtures.

In addition, in the present invention, the screw coupling grooves 1c are drilled at the edges of the light transmitting or diffusing plate 1 at predetermined intervals or at each corner thereof.

That is, the LED lighting module itself is attached to the module fixing plate 8 of various lighting fixtures (for example, a floodlight, a security lamp, a landscape lighting lamp, a house, a barn, or a factory lighting lamp) in which a plurality of LED lighting modules are integrally installed. In the state in which the radiator 3 is inserted into the perforated radiator through hole 8a, the light transmitting or diffusing plate 1 itself caught on the periphery of the radiator through hole 8a as shown in FIGS. 9), or the light transmission or diffusion to fix the socket coupling and the ventilation support 12 having a predetermined shape as shown in FIG. 13 to the light transmission or diffuser plate 1 through the screw (9) At the periphery of the plate 1, screw coupling grooves 1c were further drilled at predetermined intervals or at each corner.

At this time, the socket coupling and the ventilation support 12 is composed of a ventilation support 12b injection-molded using a spiral socket coupling tool 12a and a synthetic resin material, as shown in FIG. 12a) supplies an AC voltage to the converter 5b for power supply as well as performs a function of screwing the LED lighting module itself into a socket like a general electric bulb, and the ventilation support 12b is a spiral socket coupler. At the periphery of the body 12b-1, which is fixedly installed on the bottom of 12a, several legs 12b-2 are formed to protrude downwardly at predetermined intervals, and the lower ends of the legs 12b-2 are formed. The screw through hole (12b-3) through which the screw (9) coupled to the screw coupling groove (1c) formed in the light transmitting or diffusing plate (1) is passed through.

Therefore, the socket coupling and the ventilation support 12 itself does not interfere at all with the heat dissipation function of the heat dissipating body 3 and the heat dissipating enclosure 6 (that is, the state does not interfere with the flow of air at all). Since the lighting module itself can be screwed into the socket like a general electric bulb, the LED lighting module itself equipped with the socket coupling and the ventilation support 12 is used as a single lighting device such as a stair lamp, a signboard indirect light, and a down light. It can be used as a light fixture.
