(Including tubular objects using LEDs) refers to bulbs such as light bulbs and fluorescent lamps that have been said to be used in the past, and they themselves become illuminating light. It has a device for emitting and holding the illuminating lamp, such as a connecting part such as a plug and a connection terminal of a power cable, a housing, and a cover, and refers to an object that does not shine itself. Refers to an illuminating device in which the illuminating lamp and the luminaire are integrated and not separated and independent.

  In addition, the fluorescent lamp-shaped LED lighting tube provided in the conventional market has a built-in LED unit and a driving circuit thereof, and is an abbreviated form of the lighting device or the lighting lamp referred to here. Is attached to an existing lighting fixture or used in accordance with the shape of the fixture, and is not handled as a lighting device here.

  Therefore, in the past, straight tube and ring-shaped fluorescent lamps or LED illuminating lamps have been sold and provided as independent single products for straight tube and ring-shaped lighting tubes and lighting fixtures. Or is used according to the shape of the instrument.

The conventional lighting device is generally provided with an illumination lamp that emits light in the cover or shade, and an illumination lamp that is attached to the illumination fixture itself to emit illumination light.

JP 2008-47377 A

  In a conventional lighting device, an illumination lamp and a lighting fixture are provided independently such as a fluorescent lamp fixture and a fluorescent lamp, and only the bulb of the fluorescent bulb can be replaced with a lifetime of about 1 to 2 years. According to this, straight tube type LED illuminating lamps that have been put on the market in recent years are also used by exchanging and attaching to existing luminaires. There is a lifetime on the appliance side, and it is used without considering the difference in the lifetime.

In other words, the use of the straight tube type LED lighting lamps provided in recent years has been reused by using the existing lighting fixtures. This is because the lighting fixtures have a relatively long service life. But it is used with a difference in the lifetime of the replaced long-life straight tube LED lamp and the luminaire, and it is constantly alternating As a result, there was an inconvenience that the amount of electricity used and the brightness were inefficient due to the difference in life, and that the inherent life was shortened.

In recent years, straight tube type LED illuminating lamps have been provided in terms of energy saving and long life, and in their use, it has been proposed that they are installed and used on existing luminaires as described above. The life of lighting fixtures is generally said to be used for 10 to 20 years, although there is a large difference depending on the situation of use, and it has been used within that range. The lamp also has the same long life (40,000 to 50,000 hours). Therefore, if the existing fluorescent lamp is replaced with an old fluorescent lamp and replaced with a new straight tube type LED lamp, a difference in use time from the existing lamp is obtained. As a result, the efficiency of the electricity consumption and brightness of the new LED lighting is reduced, and the original performance cannot be achieved due to the influence of the old existing lighting fixture whose efficiency has dropped.

In addition, it is known that when the conventional fluorescent lamp is used for about one year, the illuminance decreases by about 70% and further increases, and the amount of electricity used by the fluorescent lamp increases dramatically. Similarly, it is known that the efficiency is reduced, and the illumination efficiency with respect to the amount of electricity used for LED lighting is also reduced. Based on this usage situation, the above-mentioned mixed use of lighting and lighting fixtures This is because it was not generally recognized that there was a difference in specific inefficiency.

In the first place, conventional fluorescent lamps and light bulbs are as short as about 1 to 2 years with respect to the life of lighting fixtures, and since this started with the need to replace only the bulbs of fluorescent lamps and light bulbs, they have been provided in recent years. In the straight tube type LED lighting that has started, it is necessary to consider the life of the lighting fixture before replacing only the bulbs of the conventional fluorescent lamp and bulb, which is almost the same as that of the lighting fixture. As described above, the lifespan of the LED lamp and the luminaire is about the same, and as a result of the adverse effect that the efficiency decreases when they are replaced individually, it is most efficient to replace the illuminator and the luminaire simultaneously and save energy. Can be used from the viewpoint of long life.

From these things, as described above, the original efficiency can be demonstrated by using the illumination lamp and its luminaire at the same time, but there is no proposal for simultaneous replacement of such illuminator and luminaire, Neither is provided, and improvements can be found here.

Thus, the disclosed “ceiling LED lighting device” in Patent Document 1 is an outlet for supplying power and a DC power supply unit attached to the outlet, and the lighting unit 1 including the LED light emitter 11 is connected to the DC power supply. Since it is used as an illuminating lamp by plugging it into an outlet provided with an electric part, the outlet and the DC power supply unit and the illuminating unit 1 are provided separately and used alone. Was not united.

In this way, in the prior art example of the prior art, it inherited the conventional idea of exchanging the bulb of the fluorescent lamp, in which the illumination unit 1 is removed from the outlet, and the outlet and the DC power source for supplying the power here are also intentionally provided. However, if the lighting unit 1 is changed at the same time, it cannot be easily replaced by ordinary people.

In order to effectively achieve the above object, the present invention provides, as a first solving means, a power supply receiving portion that is detachable from a ceiling or wall surface power supply portion and a lighting device support body. Or, provided on the wall surface side, and by providing the light emitting part having the LED unit and the drive circuit inside the lighting device having the support body and the shade,
The lighting device integrated with the lighting fixture is to be attached and detached from a power supply unit such as a ceiling or a wall.

As a second solution, the support body is a radiator,
The heat from the drive circuit and the LED unit is dissipated.

Furthermore, as a third solution, the LED unit is supported by the heat conductive support member and the heat conductive support member is supported by the support body.
Heat from the LED unit is dissipated by the support body through the heat conductive support member.

In addition, as a fourth solving means, by providing the LED unit in a direction parallel to the support body so that the irradiation light of the LED unit can be irradiated in a direction parallel to the support body,
The irradiation light from the LED unit is surface-emitted by a shade.

In addition, as a fifth solution, by providing a reflecting member on the facing side of the irradiation light emitted by the LED light emitting element of the LED unit,
Irradiation light from the LED unit is diffusely reflected by the shade to emit light.

The present invention is adapted to obtain an effective effect by each of the above-described means, and in particular, is a lighting device having a support body of the first solution means and a shade on the lower side thereof, and has a ceiling or a wall surface. A power supply unit that can supply power from a rosette or an end of a power cable provided to the power supply unit and a power receiving unit of a hook plug, a plug, or a cable connection terminal corresponding to the power supply unit so that the illumination device can be attached and detached. Provided on the ceiling or wall side which is the installation side of the device,
By providing an LED unit having a plurality of LED light emitting elements and a light emitting unit having a drive circuit for driving the LED unit inside the lighting device,
By directly attaching and detaching and replacing the lighting device with the lighting fixture directly from the power supply unit such as the ceiling, the lighting efficiency of the LED unit of the original lighting device can be exhibited best, and the original lifetime is also maintained. It can be provided as a lighting device integrated with a lighting fixture.

  Moreover, in exchanging as the LED lighting device integrated with the lighting fixture of the present application, the price of the conventional straight tube type LED lighting lamp is currently very expensive compared to conventional fluorescent lamps, and has become a hindrance to popularization, For example, even if compared with the amount of conventional fluorescent lamp bulbs and their lighting fixtures combined, the LED lighting lamps are more expensive than that, and when viewed from this price difference, only long life and energy saving Although the effect has not led to widespread exchange, in recent years the price of straight tube LED lighting is approaching that.

And, by using the existing fluorescent lighting fixture whose efficiency has been reduced due to deterioration and efficiency reduction due to the use of the existing lighting fixture in the invisible negative part in the above replacement, The efficiency is also reduced and the life of the new illuminating lamp is also affected. Therefore, the mixed use of old and new does not provide true long life and energy saving. It also affects the price reduction due to the mass production effect, and from this point of view, the effect of replacing the LED lighting device integrated with the lighting fixture of the present application is significant.

Furthermore, as an LED lighting device integrated with a luminaire, the shade design can be changed at that time by replacing the whole, and the direct lighting type or ring-shaped side-by-side design of the illuminating lamp that has been used in the past has changed. It can be shifted and diversified for each application as more lighting designs.

Furthermore, the straight tube type or the ring shape of the conventional straight tube type LED lighting lamp has a light emitting area limited by the surface area of the sphere, but the shade of the present application can obtain a wider light emitting area compared with the surface emitting lighting. Indirect lighting makes it difficult to cast shadows.

Moreover, by making the support body of the second solution means a heat radiator,
Compared with the heat sink of the conventional straight tube type LED lighting lamp, it is possible to obtain a great heat dissipation area and to keep the cost low by using it as a support body, and also to dissipate heat from the drive circuit and LED unit. The drive circuit and the LED unit are prevented from being deteriorated by heat, and a longer life can be secured.

Furthermore, the LED unit of the third solving means is supported by the heat conductive support member and by supporting the heat conductive support member by the support body,
The heat from the LED unit can be directly dissipated from the support member having good heat conductivity, and further can be dissipated by the support body through the heat conductive support member. Longer life can be achieved by protecting against heat and preventing deterioration due to heat.

In addition, by providing the LED unit in a direction parallel to the support body so that the irradiation light of the LED unit of the fourth solving means can be irradiated in a direction parallel to the support body,
Irradiation light from the LED unit does not become a point light source on the shade surface, but can be provided as a lighting device integrated with a lighting fixture capable of emitting light from the shade.

In addition, by providing a reflecting member on the opposite side of the irradiation light irradiated by the LED light emitting element of the LED unit of the fifth solving means,
By reflecting the irradiation light from the LED unit in the shade direction by the reflecting member, it is possible to efficiently cause the shade to be surface-emitting and also reflected in the ceiling direction, and the effect as indirect illumination of the ceiling can be obtained, Further, since the shade has a wider light emitting area, it can be provided as a lighting device integrated with a lighting fixture capable of brightly distributing light throughout the room.
Therefore, the present invention has a practically significant effect.

JP 2008-47377 A

  In a conventional lighting device, an illumination lamp and a lighting fixture are provided independently such as a fluorescent lamp fixture and a fluorescent lamp, and only the bulb of the fluorescent bulb can be replaced with a lifetime of about 1 to 2 years. According to this, straight tube type LED illuminating lamps that have been put on the market in recent years are also used by exchanging and attaching to existing luminaires. There is a lifetime on the appliance side, and it is used without considering the difference in the lifetime.

In other words, the use of the straight tube type LED lighting lamps provided in recent years has been reused by using the existing lighting fixtures. This is because the lighting fixtures have a relatively long service life. But it is used with a difference in the lifetime of the replaced long-life straight tube LED lamp and the luminaire, and it is constantly alternating As a result, there was an inconvenience that the amount of electricity used and the brightness were inefficient due to the difference in life, and that the inherent life was shortened.

In recent years, straight tube type LED illuminating lamps have been provided in terms of energy saving and long life, and in their use, it has been proposed that they are installed and used on existing luminaires as described above. The life of lighting fixtures is generally said to be used for 10 to 20 years, although there is a large difference depending on the situation of use, and it has been used within that range. The lamp also has the same long life (40,000 to 50,000 hours). Therefore, if the existing fluorescent lamp is replaced with an old fluorescent lamp and replaced with a new straight tube type LED lamp, a difference in use time from the existing lamp is obtained. As a result, the efficiency of the electricity consumption and brightness of the new LED lighting is reduced, and the original performance cannot be achieved due to the influence of the old existing lighting fixture whose efficiency has dropped.

In addition, it is known that when the conventional fluorescent lamp is used for about one year, the illuminance decreases by about 70% and further increases, and the amount of electricity used by the fluorescent lamp increases dramatically. Similarly, it is known that the efficiency is reduced, and the illumination efficiency with respect to the amount of electricity used for LED lighting is also reduced. Based on this usage situation, the above-mentioned mixed use of lighting and lighting fixtures This is because it was not generally recognized that there was a difference in specific inefficiency.

In the first place, conventional fluorescent lamps and light bulbs are as short as about 1 to 2 years with respect to the life of lighting fixtures, and since this started with the need to replace only the bulbs of fluorescent lamps and light bulbs, they have been provided in recent years. In the straight tube type LED lighting that has started, it is necessary to consider the life of the lighting fixture before replacing only the bulbs of the conventional fluorescent lamp and bulb, which is almost the same as that of the lighting fixture. As described above, the lifespan of the LED lamp and the luminaire is about the same, and as a result of the adverse effect that the efficiency decreases when they are replaced individually, it is most efficient to replace the illuminator and the luminaire simultaneously and save energy. Can be used from the viewpoint of long life.

From these things, as described above, the original efficiency can be demonstrated by using the illumination lamp and its luminaire at the same time, but there is no proposal for simultaneous replacement of such illuminator and luminaire, Neither is provided, and improvements can be found here.

Thus, the disclosed “ceiling LED lighting device” in Patent Document 1 is an outlet for supplying power and a DC power supply unit attached to the outlet, and the lighting unit 1 including the LED light emitter 11 is connected to the DC power supply. Since it is used as an illuminating lamp by plugging it into an outlet provided with an electric part, the outlet and the DC power supply unit and the illuminating unit 1 are provided separately and used alone. Was not united.

In this way, in the prior art example of the prior art, it inherited the conventional idea of exchanging the bulb of the fluorescent lamp, in which the illumination unit 1 is removed from the outlet, and the outlet and the DC power source for supplying the power here are also intentionally provided. However, if the lighting unit 1 is changed at the same time, it cannot be easily replaced by ordinary people.

In order to effectively achieve the above-mentioned problems, the present invention provides, as a first solving means, an LED lighting apparatus integrated with a lighting fixture in which a support body is substantially plate-like or substantially container-like and a shade is provided on the opposite side. An LED unit having a plurality of LED light-emitting elements, the power supply unit provided on the ceiling or the wall, and the power supply unit provided in the support body so that the power supply unit can be attached and detached. A light emitting unit having a drive circuit for driving the LED unit is provided via a heat conductive support member, and the irradiation light of the LED unit can be irradiated in a direction parallel to a ceiling or a wall surface to which the LED lighting device is attached. In addition, an LED unit is provided at a predetermined position of the support body or shade from the outer peripheral side of the support body or shade toward the center, and the LED light emitting element of the LED unit includes: By providing the reflecting member facing side of the irradiation light morphism,
The lighting device integrated with the lighting fixture is attached / detached / replaced from a power supply unit such as a ceiling or a wall, and the heat from the drive circuit and the LED unit is radiated by the support body via the heat conductive support member, and the LED unit emits the heat. The light is diffusely reflected by the shade to emit light.

The present invention has as an effective effect is obtained by the respective means described above, in particular, lighting support body of the first solution is provided shade on the opposite side with a substantially plate-shaped or substantially container shape An LED lighting device integrated with a fixture, a power supply unit capable of supplying power from a rosette or a power cable end provided on a ceiling or a wall surface, and the power supply unit so as to be detachable and replaceable from a power supply receiving unit of the lighting device The support body is provided with a power receiving portion for a hook plug, plug or cable connection terminal corresponding to
Inside the lighting device, an LED unit having a plurality of LED light emitting elements and a light emitting unit having a drive circuit for driving the LED unit are provided via a heat conductive support member,
An LED unit at a predetermined position of the support body or shade from the outer peripheral side of the support body or shade toward the center so that irradiation light can be irradiated in a direction parallel to the ceiling or wall surface to which the LED lighting device is attached. And providing a reflective member on the opposite side of the irradiation light irradiated by the LED light emitting element of the LED unit ,
By directly attaching and detaching and replacing the lighting device with the lighting fixture directly from the power supply unit such as the ceiling, the lighting efficiency of the LED unit of the original lighting device can be exhibited best, and the original lifetime is also maintained. It can be provided as a lighting device integrated with a lighting fixture.

  Moreover, in exchanging as the LED lighting device integrated with the lighting fixture of the present application, the price of the conventional straight tube type LED lighting lamp is currently very expensive compared to conventional fluorescent lamps, and has become a hindrance to popularization, For example, even if compared with the amount of conventional fluorescent lamp bulbs and their lighting fixtures combined, the LED lighting lamps are more expensive than that, and when viewed from this price difference, only long life and energy saving Although the effect has not led to widespread exchange, in recent years the price of straight tube LED lighting is approaching that.

And, by using the existing fluorescent lighting fixture whose efficiency has been reduced due to deterioration and efficiency reduction due to the use of the existing lighting fixture in the invisible negative part in the above replacement, The efficiency is also reduced and the life of the new illuminating lamp is also affected. Therefore, the mixed use of old and new does not provide true long life and energy saving. It also affects the price reduction due to the mass production effect, and from this point of view, the effect of replacing the LED lighting device integrated with the lighting fixture of the present application is significant.

Furthermore, as an LED lighting device integrated with a luminaire, the shade design can be changed at that time by replacing the whole, and the direct lighting type or ring-shaped side-by-side design of the illuminating lamp that has been used in the past has changed. It can be shifted and diversified for each application as more lighting designs.

Furthermore, the straight tube type or the ring shape of the conventional straight tube type LED lighting lamp has a light emitting area limited by the surface area of the sphere, but the shade of the present application can obtain a wider light emitting area compared with the surface emitting lighting. Indirect lighting makes it difficult to cast shadows.

Further, since the support body is a heat radiator, that also serves as the support body with much of the heat dissipation area compared to the heat radiating plate of a conventional straight-tube type LED lighting is obtained, costs less, and the driver circuit Further, heat from the LED unit can be dissipated, deterioration of the drive circuit and the LED unit due to heat can be prevented, and a longer life can be secured.

Furthermore, since the LED unit is supported by the support body via the heat conductive support member , the heat from the LED unit can be directly radiated from the heat conductive support member, and the heat conductive support member Heat can be dissipated by the support body, and thus a further heat dissipating effect can be obtained, and the LED unit can be protected from heat and further prevented from deterioration due to heat, thereby extending the life.

In addition, from the outer peripheral side of the support body or shade toward the center direction, the support body or shade is placed at a predetermined position so that the irradiation light can be irradiated in a direction parallel to the ceiling or wall surface on which the LED lighting device is attached.
