Description

  The present invention relates to a straight tube type LED lighting fixture for illumination. The straight tube type LED lighting device of the present invention is not particularly limited as long as it can be used as lighting, for example, lighting used for artificial breeding of living organisms, etc. .

Development of high-power LED (Light Emitting Diode) elements has progressed, and so-called LED illuminators have begun to spread in place of conventional white light bulb illumination and fluorescent light illumination. In particular, white LED elements, unlike conventional monochromatic LEDs that emit only monochromatic light, can emit light of a large number of wavelengths, making them suitable for use in daily lighting and industrial lighting applications. Combined with the characteristics of small size, power saving, and long life, the spread has gained momentum.
Although it is said that the lifetime is considerably longer than that of a conventional incandescent bulb, the lifetime is actually determined by deterioration due to heat, metal deterioration of the electrode portion, disconnection of internal wiring due to impact or the like.

For example, Japanese Patent Application Laid-Open No. 2010-40494 discloses a straight tube type straight LED lighting device in which LEDs are arranged in a line.
FIG. 9 is a diagram simply showing a configuration example of a conventional straight tube type LED lighting device 1.
As shown in FIG. 9, an LED electronic substrate 30 having a large number of LEDs 41 mounted on the surface thereof is attached in the straight tube member 10, and light is emitted from the surface of the LED electronic substrate 30. The bases 20 </ b> L and 20 </ b> R are attached to both sides of the straight pipe member 10. A circuit board 50 is disposed on one end of the LED electronic board 30, and an LED lighting circuit is mounted on the circuit board 50. The LED line light source 40 having a large number of LED elements 41 mounted on the surface is provided only within a portion of the straight tube member 10.

  The circuit board 50 is mounted with an LED lighting circuit and requires a certain area. In particular, it is often designed for universal use as 100V / 200V, and a switching regulator circuit is incorporated to cope with voltage fluctuation and voltage conversion assuming that the voltage quality is not good in other countries. There are many cases. The electronic circuits are integrated so as to be integrated and mounted on the circuit board 50 at one end of the LED electronic board 30.

JP 2010-40494 A

  The problem with the conventional straight tube type LED lighting device is that it cannot always be said that a sufficient amount of light is secured. Since the conventional straight tube type LED lighting device is an alternative to the conventional fluorescent lamp, it is assumed that it is directly attached to a fluorescent lamp socket in a room or office. Indoors and offices are designed and provided with light intensity in the usage environment, so if the light intensity equivalent to that emitted by conventional fluorescent lamps is not obtained, the indoor illuminance will not be the same as the architectural design, When a conventional fluorescent lamp is replaced with a conventional straight tube LED lighting device, the user may have an impression that the room is dark, and it may actually be inconvenient because it is dark.

  In order to increase the amount of light in the conventional straight tube type LED lighting device, firstly, the amount of light per one arranged LED is increased. This depends on the development of an LED element that emits a larger amount of light. What is necessary is just to select the thing with the largest light quantity as much as possible in consideration of cost in the market.

Next, the 2nd method of increasing light quantity in the conventional straight tube | pipe type LED lighting apparatus is to increase the number of LED arrange | positioned. Certainly, if the number of LED elements is increased, the amount of light as a whole increases.
However, since the cost increases according to the number of LED elements, simply increasing the number of LED elements does not solve the problem. Moreover, since the straight tube type LED lighting device is an alternative to the conventional fluorescent lamp, its length is limited. Therefore, there is a limit to the number of LED elements that can be mounted on one straight tube LED lighting device. Therefore, the number of LEDs to be arranged is also limited.

Next, the 3rd method of increasing light quantity in the conventional straight tube | pipe type LED lighting apparatus is to increase the light emission area in one straight tube | pipe type LED lighting apparatus. This is related to increasing the number of the LED elements mentioned above, but if the light amount per unit area is the same, the larger the light emitting area per one straight tube type LED lighting device is, The total amount of light increases.
However, as described above, since the straight tube type LED lighting device is an alternative to the conventional fluorescent lamp, its length is limited. For this reason, there is a limit to the light emitting area in one straight tube type LED lighting device. FIG. 9B is a diagram showing a portion that emits light in the configuration example of FIG. As shown in FIG. 9 (b), the portion that emits light is a portion corresponding to a part of the straight tube member 10, and the circuit board 50 at the end thereof is a portion that does not emit light. That is, in the conventional straight tube type LED lighting device 1, the light emission area is limited to a portion corresponding to a part of the straight tube member 10.

  In view of the above problems, the present invention is a straight tube type LED lighting device that is attached to a conventional fluorescent lamp socket and can be used as a substitute for a fluorescent lamp. It aims at providing a type LED lighting fixture.

In order to achieve the above object, a straight tube type LED lighting device of the present invention includes a base part at both ends attachable to a socket of a straight tube type fluorescent lamp, a straight pipe member passed between the base parts, an electronic In a straight tube type LED illuminator comprising a substrate, an LED line light source arranged in a line of a large number of LED chips along the electronic substrate, and an electronic control circuit for controlling power supply to the LED line light source The mounting portion of the electronic control circuit is provided at two locations near the base at one end and near the base at the other end, each mounting portion is extended to the inside of each base portion, and the extension portion is The electronic control circuit is configured to be used as at least a part of the mounting location, and the electronic control circuit is divided into two electronic circuit modules, and the electronic device mounted as the electronic control circuit is mounted Classified according to the places the large electronic devices mounting height on the extension of the interior of the mouthpiece was arranged electronic elements of the electronic control circuits other than it on the mounting portion other than the mouthpiece portion It is characterized by this.

Straight-tube type LED lighting fixture of the traditional, since the mounting portion of the electronic circuit mounted as an electronic control circuit is arranged concentrated in one place towards the end of the straight tube member, the electron of the straight pipe member The portion where the circuit is mounted is in a range where light cannot be emitted, and the range where the LED element can be arranged to emit light is narrowed accordingly. On the other hand, the straight tube type LED lighting device of the present invention can be provided with the mounting portion of the electronic control circuit being distributed in two at the left and right ends and extending the mounting portion to the inside of the base portion. Therefore, the mounting area of the electronic control circuit in the straight pipe member can be reduced, the arrangement area of the LED elements in the straight pipe member can be increased, and the light emission area in the straight pipe member is increased.
Here, if it sees according to the kind of electronic element mounted as an electronic control circuit, if the electronic element with a large mounting height will be in the range of a straight tube member, there exists a possibility that the light emitted by the LED element may be interrupted. Therefore, it is preferable to classify electronic elements to be mounted as an electronic control circuit according to the mounting height, and to arrange electronic elements having a large mounting height in preference to the extended portion in the base.

The extended portion of the electronic substrate can be provided on the same plane as the electronic substrate, or can be provided on a plane that intersects the plane formed by the electronic substrate. Moreover, it is also preferable that the intersection of the extended portion of the electronic substrate and the plane formed by the electronic substrate be orthogonal and provided inside the base. The latter effectively reduces the mounting area of the electronic board in the range of the straight pipe member by effectively using the internal space inside the base and mounting the electronic board in three dimensions.

  In particular, among the electronic elements employed in the electronic control circuit, a non-chip type cylindrical electronic element is disposed in preference to the extension portion in the base, and the non-chip type is disposed on the electronic substrate in the range of the straight pipe member. By arranging the cylindrical electronic elements so as not to be mounted, the light emission amount of the straight tube type LED illuminator can be ensured as large as possible.

  Next, in the above configuration, it is preferable to reduce the mounting area of the electronic control circuit itself. Therefore, the mounting area is reduced by substituting a resistance element or an impedance element for an electronic circuit corresponding to a switching regulator mounted on a conventional straight tube type LED illuminator, and further generated by a resistance element or an impedance element. In order to release heat, it is preferable to provide a metal body serving as a heat path for directly connecting the resistance element or impedance element and the base. By reducing the area of the electronic control circuit, the mounting area occupying the range of the straight pipe member of the electronic control circuit can be reduced.

According to the straight tube type LED illuminator of the present invention, the mounting portion of the electronic control circuit is distributed in two at the left and right ends, and the mounting portion can be extended to the inside of the base portion. Therefore, the mounting area of the electronic control circuit in the straight pipe member can be reduced, the arrangement area of the LED elements in the straight pipe member can be increased, and the light emitting area in the straight pipe member can be increased.
In particular, the extended portion of the electronic substrate, which is the mounting portion of the electronic control circuit, is on the plane that intersects the plane formed by the electronic substrate on which the LED element is mounted, that is, the electronic substrate by effectively using the internal space inside the base By mounting the three-dimensionally, the mounting area of the electronic substrate in the range of the straight tube member can be reduced, and the light emission amount of the straight tube type LED lighting device can be ensured as large as possible.
Also, the electronic control circuit itself can reduce the mounting area by substituting a circuit equivalent to a switching regulator, and can secure a large amount of light emitted from the straight tube type LED lighting device.

  Hereinafter, embodiments of the straight tube type LED lighting device of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number, etc. shown in the following examples.

The example of the straight tube | pipe type LED lighting fixture of this invention concerning Example 1 is shown. Hereinafter, the light emission surface of LED illumination is demonstrated as an upper surface (plane).
1 is a plan view of a straight tube type LED lighting device 100, FIG. 2 is a side view of the straight tube type LED lighting device 100, and FIG. 3 is a front view of the straight tube type LED lighting device 100. FIG. 1B is a diagram showing the internal structure extracted so that the relationship between the symbols can be easily understood.
The straight tube type LED lighting device 100 of the present invention can be used as an alternative by directly mounting it on a socket portion of an existing fluorescent lamp fixture installed on a ceiling or the like.
In the configuration example of the first embodiment, the straight tube type LED lighting device 100 includes a straight tube member 110, a base 120, an electronic substrate 130, an LED line light source 140, and an electronic control circuit 150.

  The straight pipe member 110 is a pipe-like member that replaces a conventional fluorescent illumination lamp. At least the illumination surface is a pipe made of transparent plastic or glass, and is generally cylindrical. In this configuration example, it is assumed that the straight pipe member 110 is formed in a cylindrical pipe shape using a transparent resin material such as transparent or translucent polycarbonate resin, acrylic resin, or methacrylic resin. A base part 120 is provided at both ends. The length in the axial direction between the cap portions 120 attached to both ends of the straight pipe member 110 is the same length as that of the existing fluorescent lamp.

The base part 120 is a member provided at both ends of the straight pipe member 110 and has an external shape of a base of a conventional fluorescent lighting lamp. The straight pipe member 110 is attached to each end. Here, the base part 120L is provided at the left end, and the base part 120R is provided at the right end.
Two terminals 121 corresponding to plugs are protruded from the outer surface of each base part 120 in a state of being electrically insulated in parallel. These terminals 121 are formed according to the same standard as a conventional fluorescent lamp, and can be attached to a socket portion of an existing fluorescent lamp fixture.
Although there is an internal space inside the base portion 120, in this configuration example, as will be described later, extension portions 132L and 132R obtained by extending the electronic substrate 130 are provided. The extension portions 132L and 132R will be described later.

The electronic board 130 is a board on which the LED line light source 140 and the electronic control circuit 150 are mounted. In this example, as shown in FIG. 1, the electronic substrate 130 is formed in an elongated shape in a strip shape and is provided over the entire length of the straight pipe member 110. As shown in FIGS. 2 and 3, the electronic substrate 130 is provided near the upper part of the inner surface of the straight pipe member 110. For example, it is fixed along the inside of the straight pipe member 110 by a member such as a synthetic resin clip.
The electronic substrate 130 has a main body portion 131 and an extension portion 132. The main body portion 131 is disposed inside the straight tube member 110, and is a place where the LED line light source 140 on which the LED element 141 is mounted is disposed as will be described later. On the other hand, the extended portion 132 enters the inside of the base 120 as will be described later, and is provided as a place where at least a part of the electronic circuit module 151 of the electronic control circuit 150 is mounted. This configuration will be described in detail later.

  The LED line light source 140 is a large number of LED (white light emitting diode) elements in which a large number of LED chips are mounted in a line along the electronic substrate 130 in the straight tube member 110. As shown in FIG. 1 and the like, in this configuration example, the LED line light source 140 is mounted on the front (front) side of the straight tube member 110 so that 30 LEDs 10 irradiate the front with light. Therefore, the front side (surface side) of the LED line light source 140 is a light irradiation surface.

The LED element 141 is a chip having a light emitting surface of a white LED element on the front surface and an electrode surface on the back surface. In this example, the LED element 141 is a surface mount type (SMD type) LED element. It shall emit light that appears to be pure white visually.
The LED elements 141 are arranged in a straight line, and the LED line light source 140 is formed. For example, 30 LEDs 30 are mounted so as to irradiate the front surface with light.

  The electronic control circuit 150 is an electronic circuit that receives a voltage supplied from the outside and controls the LED line light source 140 to supply necessary power. There are no particular limitations on the electronic elements and circuit configurations mounted as the electronic control circuit, but various electronic elements such as electrolytic capacitors, resistance elements, rectifiers, surge absorbers, power thermistors, and the like are mounted. An LED (white light emitting diode) is provided as the light emitting element.

Here, in the straight tube type LED lighting device 100 according to the present embodiment, the electronic control circuit 150 is divided into two electronic circuit modules 151L and 151R. By dividing the module into two, the advantage is that the electronic circuit module 151 per unit becomes small and the arrangement thereof is easy to devise.
In this example, the electronic control circuit 150 occupies the electronic substrate 130 in the range of the straight tube member 110 by being distributed and mounted in two mounting portions near the base portion 120L at one end and near the base portion 120R at the other end. The mounting area is reduced.

Here, in order to arrange the electronic circuit modules 151L and 151R at positions that do not interfere with LED irradiation as much as possible, the inner space of the base part 120 is used.
As shown in FIGS. 1 and 3, both end portions of the electronic board 130 are extended to the inside of the base portions 120 </ b> L and 120 </ b> R, and the extended portions 132 are mounted on the electronic circuit modules 151 </ b> L and 151 </ b> R of the electronic control circuit 150. It is used as a place. In this example, the extended portion 132 of the electronic substrate 130 is an example in which the electronic substrate 130 is provided as it is on the same plane. At least a part of the electronic circuit modules 151L and 151R is mounted on the extension part 132 of the electronic substrate 130 inside the base parts 120L and 120R.

An example of the lighting circuit of each LED element 141 of the LED line light source 140 will be described.
FIG. 4 is an example of an electronic circuit diagram in which a general conventional electronic control circuit is integrally provided. On the other hand, FIG. 5 is an example of an electronic circuit diagram in which the electronic control circuit 150 is divided into two electronic circuit modules 151L and 151R.

  First, an example of an electronic circuit in which a general conventional electronic control circuit is integrally provided will be described. As shown in FIG. 4, a power thermistor PS153 is connected between terminals on the DC output side of the rectifier RC152, a smoothing electrolytic capacitor C154 is connected, and a voltage control circuit 155 that controls the voltage is further connected. Thirty LEDs 141 are connected in series. A Zener diode Z is connected in parallel to each of the 30 LEDs 141, and it is devised to allow a current to flow in the forward direction even when each LED 141 is disconnected. The number of LED elements 141 is adjusted and connected in series so that the rated voltage (for example, 3.3 V) is applied to each LED element 141 in operation, whereby the DC output side of the rectifier RC152 is connected to the LED element 141. The voltage, that is, the power supply voltage is divided, and the rated voltage is applied to each LED element 141.

  When this electronic control circuit 150 is mounted on an existing fluorescent lamp apparatus 200 and a commercial voltage of AC100V is applied, a commercial power supply of AC100V is applied between the terminals. A slightly higher DC voltage is output. The direct current output voltage of the rectifier RC152 is applied to the whole of the 30 LED elements 141 connected in series, and each LED element 141 is applied with a voltage obtained by dividing the voltage applied to the whole by 30 (LED rated voltage). become. The voltage of the entire LED line light source 140 at that time is subjected to constant voltage control by the voltage control circuit 155. In this configuration example, the voltage control circuit 155 is an example of a constant voltage power supply circuit in which two transistors TR1 and TR2 and resistors R1 and R2 are connected, and the voltage applied to the entire LED line light source 140 is determined. Operates to control constant voltage.

  According to the electronic control circuit 150 shown in FIG. 4, all the elements other than the LED element 141 are mounted on one end side (for example, the left side) of the electronic substrate 130 in a concentrated manner. The prior art does not disclose a technique for effectively using the inner space of the base part 120. As a result, the mounting part of the electronic control circuit 150 shown in FIG.

  On the other hand, the straight tube type LED lighting device 100 according to the first embodiment is an example of an electronic circuit in which the electronic control circuit 150 is divided into two electronic circuit modules 151L and 151R. The operation of each element and each circuit is the same as that of the conventional type shown in FIG. 4 and is omitted here, but it is divided into two modules as compared with the circuit diagram of FIG.

In the example shown in FIG. 5, 30 LEDs 141 are connected in series between terminals on the DC output side of the rectifier RC152 via a voltage control circuit 155 that controls the voltage. A Zener diode Z is connected in parallel to each of the 30 LEDs 141, and it is devised to allow a current to flow in the forward direction even when each LED 141 is disconnected. On the other hand, a power thermistor PS153 and a smoothing electrolytic capacitor C154 are connected to the terminal end side of the 30 LEDs 141. According to the electronic control circuit 150 shown in FIG. 5, the LED element 141 is arranged on the straight pipe member 110, and elements relating to the rectifier RC152 and the voltage control circuit 155 are arranged on one end side (for example, the left side) of the electronic board. The elements relating to the power thermistor PS153 and the electrolytic capacitor C154 are arranged on the other end side (for example, the right side) of the electronic substrate. That is, in this example, the element related to the rectifier RC152 and the voltage control circuit 155 on one end side of the electronic board is the electronic circuit module 151L, and the element related to the power thermistor PS153 and electrolytic capacitor C154 on the other end side of the electronic board is the electronic circuit module 151R. Become.
As described above, when the electronic control circuit 150 is divided into the two electronic circuit modules 151L and 151R, the electronic circuit module 151L and the electronic circuit module 151R can be devised separately.

  Furthermore, in the present invention, a device for effectively using the inner space of the base portion 120 is provided as a mounting portion of the electronic circuit modules 151L and 151R. Therefore, at least a part of the electronic circuit modules 151L and 151R is accommodated in the inner space of the base part 120 at both ends, and the area mounted on the straight pipe member 110 is reduced.

In particular, in designing the mounting positions of the electronic circuit modules 151L and 151R, the electronic elements mounted as the electronic control circuit 150 are classified according to the mounting height, and the electronic elements having a large mounting height are arranged in the extension part 132 in the base part 120. It is advantageous to place it in preference to.
For example, many elements such as transistors and thermistors are miniaturized on a chip, but a capacitor having a large capacity is a large three-dimensional element having a height. That is, it is a non-chip type cylindrical electronic element.

  If this three-dimensional element is provided in the range of the straight tube member 110, the arrangement of the LED elements 141 is likely to be affected, and the light emission of the LED elements 141 is likely to be hindered. Therefore, if it is arranged in the base parts 120L and 120R in preference to the extended part 132 having a large space that can be used three-dimensionally, the electronic substrate 130 in the range of the straight pipe member 110 has a non-chip type cylindrical electron. It can arrange | position so that an element may not be mounted.

  Similar to the first embodiment, the straight tube type LED lighting device 100a according to the second embodiment includes a straight tube member 110, a base 120, an electronic substrate 130, an LED line light source 140, and an electronic control circuit 150. However, the straight tube type LED lighting device 100a according to the second embodiment is provided such that 133a, which forms part of the extended portion 132a of the electronic substrate 130a, intersects the plane formed by the main body portion 131a of the electronic substrate 130a. Here, the surfaces are particularly orthogonal.

  FIG. 6 is a plan view of the straight tube type LED lighting device 100a of the second embodiment, FIG. 7A is a side view of the straight tube type LED lighting device 100a of the second embodiment, and FIG. 7B is a base portion 120L. The figure which looked at from the inside is shown. FIG. 8 is a front view of the straight tube type LED lighting device 100a according to the second embodiment. FIG. 6B is a view showing the internal structure taken out so that the shapes of the extended portions 132a and 133a can be easily understood. FIG. 6B is a perspective view so that the structure of the electronic substrate 130a can be clearly understood.

As shown in FIGS. 6, 7, and 8, in this configuration example, extension portions 132aL and 132aR are provided at both ends of the main body portion 131 of the electronic substrate 130a, and some of the extension portions 133aL and 133aR are vertically suspended. It is provided to do. The shapes of the extension parts 133aL and 133aR are circular corresponding to the cross section of the base part 120. As described above, the extension portions 133aL and 133aR are provided inside the base portion 120 while providing a surface for mounting the electronic circuit element, so that the space other than the straight tube member 110 of the straight tube type LED lighting device 100a is effectively utilized. can do.
Except that the extended portions 133aL and 133aR are suspended at both ends of the main body portion 131a of the electronic substrate 130a, the same as the first embodiment.

In this configuration example, as shown in FIG. 5, the elements related to the rectifier RC152 and the voltage control circuit 155 are arranged as the electronic circuit module 151a with respect to the extension portion 133aL, and the power thermistor PS153, electrolysis is provided with respect to the extension portion 133aR. Elements relating to the capacitor C154 are arranged as an electronic circuit module 151b.
As described above, when the electronic control circuit 150 is divided into the two electronic circuit modules 151a and 151b, the electronic circuit module 151a and the electronic circuit module 151b can be separately arranged on the extension portions 132a and 132b.

As shown in FIG. 6, when the straight tube type LED lighting device 100 a is viewed from the front, it can be seen that the straight tube member 110 as a whole is a light emitting portion, and no element relating to the electronic control circuit 150 is disposed. That is, all the elements related to the electronic control circuit 150 are mounted on either of the base parts 120a and 120b, and the entire straight pipe member 110 is secured as a light emitting region.
In the above configuration example, the extension parts 133aL and 133aR are substantially circular discs suspended from both ends of the main body part 131a, but may be provided obliquely with respect to the main body part 131a. Also, it may be other than circular.

It will be understood that various modifications can be made without departing from the scope of the invention.
