Description

Lamps and lighting fixtures

technical field

The utility model relates to a lamp and a lighting device using a light-emitting element.

Background technique

In recent years, semiconductor light-emitting elements such as light-emitting diodes (LED: Light Emitting Diode) have been used in various lamps as energy-efficient light sources.

The LED lamp using the above-mentioned LED is equipped with an LED module (light-emitting module), and by appropriately selecting and using the shape of the LED module, a straight tube-shaped lamp (straight-tube LED lamp) and a bulb-shaped lamp (bulb-shaped LED lamp) have been proposed. . In any lamp, an LED module configured by arranging a plurality of LEDs on a substrate is used (for example, refer to Patent Document 1).

Patent Document 1 Japanese Unexamined Patent Publication No. 2009-43447

However, among LED lamps, LED lamps having omnidirectional light distribution characteristics that extract light from all directions are required. However, in the conventional LED lamp, since the LED module is formed by mounting the LED on one side of the substrate, light cannot be supplied to the side of the substrate on which the LED is not mounted, that is, the light cannot be supplied to the side of the substrate. On the back, like this, it is difficult to realize an LED lamp with all-round light distribution characteristics.

Here, it is considered that the substrate is configured to have translucency, and the light of the LED is transmitted through the substrate and supplied to the back surface of the substrate. It is also conceivable to provide the inner surface of a frame such as a straight pipe with a light diffusing function, diffuse and reflect the light of the LED on the inner surface of the frame, and provide the light to the back surface of the substrate. However, the structure widely used in LED lamps is to arrange a plurality of LED modules on the surface in order to easily install the LED modules in the housing and efficiently dissipate the heat of the LEDs, and to connect them with the inside of the housing. A surface-bonding submount is disposed on the backside of the substrate. In such a configuration, most of the light directed from the LED module toward the base is absorbed by the base due to transmission through the substrate or diffuse reflection on the inner surface of the housing. LED lights with all-round light distribution characteristics.

In contrast, for the structure in which the LED module is directly bonded to the inner surface of the frame without providing a base, the above-mentioned problems do not occur, but it is necessary to bond a plurality of LED modules to the inner surface of the frame one by one. Therefore, the assembly of the LED lamp becomes complicated. Moreover, it is relatively difficult to fix the LED module to the frame while aligning the frame with the central axis of the LED module and achieving a good light distribution balance.

Utility model content

Therefore, in view of the above-mentioned problems, the present invention aims to provide a lamp and a lighting device which have all-round light distribution characteristics and are easy to assemble.

In order to achieve the above object, a lamp according to an embodiment of the present invention includes: an elongated frame body; a light emitting module provided inside the frame body; the light-emitting element on the surface; and the base, which holds the light-emitting module, at least a part of the base is arranged inside the frame, and the base is combined with the frame, and the base is combined with the frame On a surface perpendicular to the tube axis direction, the light emitting module has a light distribution angle greater than 180 degrees centered on the light emitting element, and all parts of the base are located outside the light distribution angle.

According to this embodiment, since the light-emitting module has a light distribution angle larger than 180 degrees, light can be supplied to the side of the light-emitting element where the substrate is not provided, that is, the back side of the substrate, thereby realizing a lamp with omnidirectional light distribution characteristics. . Furthermore, since the base for holding the light emitting module is provided, the frame body and the light emitting module can be easily integrated, thereby simplifying the assembly of the lamp. At this time, since the base is located outside the light distribution angle of the light emitting module, the light directed toward the back side of the substrate is not absorbed by the base. In this way, it is possible to realize a lamp that has omnidirectional light distribution characteristics and is easy to assemble.

Here, the light distribution angle may be not less than 280 degrees and not more than 320 degrees.

According to this embodiment, since the light distribution angle is not less than 280 degrees and not more than 320 degrees, it is possible to suppress light absorption by the base (self-absorption), and to maximize the light distribution characteristics.

Furthermore, the base may be provided so as to close an opening formed on the surface of the frame, and the surface of the base may be exposed to the outside of the frame through the opening.

According to this embodiment, the base can function as a housing different from the elongated housing, and since a part of the base is in contact with outside air, heat from the light emitting element can be efficiently dissipated. In this way, not only can the temperature rise of the light-emitting element be suppressed, but also the life of the light-emitting element can be prolonged, and a decrease in the light output of the light-emitting element itself can be suppressed.

In addition, the opening may be provided so as to extend from one end of the frame in the tube axis direction to the other end, and the base may be formed by forming an opening with the frame. The two ends of the frame in the circumferential direction are fitted together, and the fitted state is slid along the direction of the tube axis to be integrated with the frame.

According to this embodiment, since the base and the frame are integrated by slidingly inserting the base into the frame, assembly of the lamp can be simplified.

In addition, the base may have a flat plate, both ends of the flat plate are fitted to both ends of the frame in the circumferential direction, and the surface of the flat plate is exposed to the frame through the opening. an outer side of the body; and a protruding portion protruding from the back of the flat plate toward the inside of the frame, and the top of the protruding portion is joined to the back of the substrate.

According to this embodiment, the position of the light emitting module inside the housing can be changed by adjusting the height of the protrusion from the flat plate. In this way, the frame body can be aligned with the central axis of the light emitting module, thereby easily achieving a good light distribution balance.

In addition, the abutment may include: a flat plate whose surface is joined to the inner surface of the frame; The top is bonded to the backside of the substrate.

According to this embodiment, the position of the light emitting module inside the housing can be changed by adjusting the height of the protrusion from the flat plate. In this way, the frame body can be aligned with the central axis of the light emitting module, thereby easily achieving a good light distribution balance. In this case, openings and the like may not be formed in the frame, and a general tubular frame may be used, so that the assembly of the lamp can be further simplified.

Furthermore, the substrate may transmit light from the light emitting element.

According to this embodiment, since the light from the light emitting element can be supplied to the back side of the substrate so that the light is transmitted, the light distribution angle of the light emitting module can be increased.

In addition, the protruding portion may be smaller than the substrate in a plan view of the substrate.

In addition, a reflective surface for reflecting light from the light-emitting element toward the inside of the housing may be formed on the inner surface of the housing.

According to this embodiment, it is possible to supply light to the back side of the substrate so that the light from the light-emitting element is reflected light.

In addition, the base may be a radiator made of metal.

According to this embodiment, the heat of the light-emitting element can be effectively dissipated by the radiator.

Moreover, the illuminating device which concerns on one Embodiment of this invention is equipped with the above-mentioned lamp.

According to this embodiment, it is possible to realize an illuminating device that has omnidirectional light distribution characteristics and is easy to assemble.

According to the present invention, it is possible to realize a lamp and an illuminating device which have all-round light distribution characteristics and are easy to assemble.

When a lighting circuit is provided inside the LED lamp 100, the lighting circuit is provided in one base 201, and the other base 201 is used only when it is attached to a lighting fixture.

The frame body 203 is a glass tube, or a plastic tube such as an acrylic resin tube or a polycarbonate tube. The straight pipe before sealing is a straight pipe of the same specification. The term "tubular shape" in this embodiment means that, as in the case 203 shown in FIG. 2 , even if a part has a slit or the like and a part is separated, as long as the virtual state is tubular. As a straight pipe, for example, the length is 1198 mm, the outer diameter is 30 mm, and the thickness is 0.7 mm. The straight pipe is made of, for example, soda lime glass, and the composition of this glass may be 70 to 72% of silicon dioxide (SiO2). In addition, the outer surface and inner surface of the frame body 203 may be subjected to diffusion treatment by coating silica, calcium carbonate, and the like as necessary.

The lamp base 201 can be appropriately selected according to the lighting fixture to which the LED lamp 100 is installed, for example, a G-type lamp base or the like is adopted.

The LED module 300 is a COB (Chip On Board: chip on board) type light-emitting module, and includes a substrate 301, a phosphor-containing resin 302 and LEDs 321 constituting a light-emitting portion. The LED module 300 is a linear module. On the surface of the substrate 301, a plurality of LEDs 321 are arranged in a row along the length direction (X direction) of the substrate 301 through a chip adhesive or the like, so that they are mounted (chip bonded) in a linear shape ( one-dimensional shape).

However, the shape of the LED module is not particularly limited. In addition to the above-mentioned structure of directly encapsulating LEDs mounted on the substrate with resin (COB type), it can also be an SMD (Surface Mount Device: surface mount) type, that is, , The LED is installed in a resin or ceramic case in advance, and in this state, it is sealed with a light-transmitting member such as resin.

The substrate 301 is elongated and rectangular, and is, for example, a translucent alumina substrate, a ceramic substrate such as aluminum nitride, a resin substrate, a glass substrate, a metal-based substrate, or a flexible substrate. The substrate 301 has translucency, and can transmit visible light emitted from the light emitting part, that is, can transmit white light from the phosphor-containing resin 302 including light emitted by the LED 321 . The substrate 301 has a size that can be arranged inside the frame body 203, has a width (length in the short direction (Y direction) perpendicular to the longitudinal direction of the substrate 301) and thickness smaller than the inner diameter of the frame body 203, and has a thickness in the longitudinal direction. The length is shorter than the length of the frame body 203 in the tube axis direction, for example, the length in the longitudinal direction is 14 cm and the thickness is 1 mm.

Here, the length in the longitudinal direction of the substrate 301 is represented by L1, and the length in the short direction is represented by L2. In this case, as an example of L1 and L2, it is defined by the relational expression 10≦L1/L2.

As the blue LED chip, a gallium nitride-based light-emitting element with a central wavelength of 440 nm to 470 nm, which is made of an InGaN-based material, or the like can be used.

The phosphor-containing resin 302 is dome-shaped, and its cross section is substantially semicircular in shape protruding upward, and the phosphor-containing resin 302 is provided so as to extend linearly along the arrangement direction of the LEDs 321 . Phosphor-containing resin 302 is provided in correspondence with a plurality of LEDs 321, and emits fluorescence by receiving light from the corresponding LEDs 321, thereby serving as a wavelength conversion layer that converts the wavelength of light from the corresponding LEDs 321, and can control the corresponding LEDs 321. Seal and protect. In order to easily make the phosphor-containing resin 302 into a dome shape, it is preferable to use a material with high thixotropy. Furthermore, the encapsulant (wavelength conversion layer) for encapsulating the LED chip is not limited to resin, and for example, a transparent material such as glass known as chip encapsulation may be used.

The phosphor-containing resin 302 contains an optical wavelength converter composed of phosphor fine particles and the like. For example, when the LED 321 is a blue LED, in order to obtain white light, the phosphor-containing resin 302 is formed by dispersing yellow phosphor particles, which are phosphor particles, in a silicone resin. As the yellow phosphor particles, YAG (yttrium, aluminum, garnet)-based phosphor materials, silicate-based phosphor materials, and the like can be used.

The frame body 203 is provided with an opening 205 extending from one end portion of the frame body 203 to the other end portion along the tube axis direction. Both ends of the frame body 203 in the circumferential direction in which the opening 205 is formed are fitted. Specifically, recesses 313 and 314 extending in the direction of the pipe axis are provided on the end faces of both end portions in a direction (Y direction) perpendicular to the pipe axis direction of the flat plate 310, and between the recesses 313 and 314 and the frame body 203 Both ends in the circumferential direction of the opening 205 are fitted. Therefore, the width of the recesses 313 and 314 is formed to be substantially equal to the thickness of the frame body 203 . In a state where the recesses 313 and 314 are fitted to the frame body 203 , end faces of the frame body 203 at both ends in the circumferential direction on which the opening 205 is formed are in contact with the bottom faces of the recesses 313 and 314 .

At this time, in order to obtain the maximum light distribution characteristic, the light distribution angle is preferably not less than 280 degrees and not more than 320 degrees. Even better, the light distribution angle is below 300 degrees, and the best is 300 degrees. Accordingly, the loss due to self-absorption (light absorption by the submount 204 itself) can be reduced, and the luminous efficiency can be improved.

The width of the flat plate 310 and the height of the protruding portion 311 are set on a plane perpendicular to the tube axis direction of the frame body 203, so that all parts of the base 204, that is, all parts of the flat plate 310 and the protruding portion 311 are located in the LED module 300. outside of the light distribution angle. That is to say, the width of the flat plate 310 and the height of the protruding portion 311 are set so that all parts of the base 204, that is, all parts of the flat plate 310 and the protruding portion 311 can be located at a light distribution angle smaller than 180 degrees of the LED module 300.

Accordingly, the LED module 300 and the base 204 are integrated.

Next, the base 204 is inserted from the end of the frame 203 in the tube axis direction ( FIG. 5( b )). Then, the base 204 is slid along the tube axis direction in a state where both ends of the frame 203 in the circumferential direction of the opening 205 of the frame 203 are fitted with the base 204 ( FIG. 5( c )). . Accordingly, the housing 203 and the base 204 are integrated.

Furthermore, the frame body 203 and the LED module 300 can be easily integrated by the base 204, and the assembly of the LED lamp 100 can be simplified. At this time, since the base 204 is located outside the light distribution angle of the LED lamp 100, the light directed toward the back side of the substrate 301 is not absorbed by the base 204. In this way, it is possible to realize the LED lamp 100 which has omnidirectional light distribution characteristics and is easy to assemble.

Moreover, according to the LED lamp 100 of this embodiment, since a part of the base 204 is in contact with outside air, the heat|fever of LED321 can be radiated efficiently. In this way, the temperature rise of LED321 can be suppressed and the service life can be extended, and the fall of the light output of LED321 itself can be suppressed.

Furthermore, according to the LED lamp 100 of this embodiment, by slidingly inserting the base 204 into the frame body 203, the base 204 and the frame body 203 can be integrated, and the assembly of the LED lamp 100 can be simplified.

In addition, in the above-mentioned embodiment, the one-side feeding type lamp in which the power is fed from one base 201 of the housing 203 has been described, but a double-feeding lamp in which power is fed from both ends of the housing 203 may also be used. shaped lamp.

In addition, in the above-mentioned embodiment, although the frame body 203 has a circular tube shape, it is not limited thereto, and it is sufficient as long as it is a tube shape.

In addition, in the above-mentioned embodiment, although the cross-sectional shape of the substrate 301 is rectangular, it may be a polygonal substrate other than a quadrangular (rectangular) shape. That is, the substrate 301 may be a triangular prism, a pentagonal prism, a hexagonal prism, or the like.

Furthermore, in the above-described embodiments, the substrate 301 has light transmission. However, the substrate 301 does not have to be light-transmissive as long as light can be supplied to the rear side of the substrate 301 . For example, it can be realized by reducing the width (width in the Y direction) of the substrate 301 .

Furthermore, in the above-mentioned embodiment, in order to provide more light to the rear side of the substrate 301 , the inner surface of the frame body 203 may have an optical function for the light emitted by the LED module 300 . Optical function such as shown in Figure 10, the inner surface of the frame body 203 is processed into a shape capable of concentrating and diffusing light (for example, with a concave-convex shape), and a reflective surface is formed on the inner surface of the frame body 203, by making the LED321 The light is diffused and reflected to the inside of the frame body 203 to achieve. Furthermore, the processing of the shape shown in FIG. 10 may be performed on all the inner surfaces of the frame body 203, or may be processed on the outer surface of the frame body 203.

The present invention can be applied to lamps using light-emitting elements such as LEDs, and in particular, can be applied to LED lamps as alternative lighting to straight-tube fluorescent lamps and lighting devices equipped with such LED lamps.
