Description

The present invention relates to the structure of a long surface emitting LED light emitter used in various products.

Conventionally, products using LEDs as surface emitters have been used in various product fields. For example, it is used in the interior of automobiles, front grills, mobile displays, etc. to draw attention to what is seen and to give an aesthetic appearance. The structure is such that a board with LEDs mounted in a housing with a certain spread or a long housing is housed, and the LED light emitted through the housing is configured in a predetermined module such as a surface light emitter or a line light emitter. It was done.

The LED light emitter has a feature that the straightness of light is high. Therefore, it has been pointed out that the LED light emitter has problems that the light emitting area is narrow and that the light emission becomes uneven due to uneven brightness. As a proposal for improving these problems, for example, Patent Document 1 discloses a light source device having a wide light emitting region.

The light source device disclosed in Patent Document 1 includes a tubular transparent cover, translucent terminal fixing portions attached to both ends of the transparent cover in the longitudinal direction, and a plurality of light sources installed inside the transparent cover.

However, the LED board in the conventional surface-emitting LED module is fixed in the housing, the light emission directing destination directly faces the light diffuser plate of the housing, and the light diffusion in the housing is insufficient, and each housing alone. Each connection is not enough and the surface emitting LED module is easily disassembled and damaged, and the flexibility of the surface emitting LED module is insufficient, so it cannot be completely installed according to the shape of various applied products and the LED function is sufficient. In addition, there are many problems that cannot be demonstrated in general, and various problems such as complicated means of attaching to products to which LED modules are applied and poor workability have occurred in general circular cross-section modules. This has hindered the widespread use of LED modules.

In the present invention, in order to solve such a problem, the surface light emitting LED module in the housing is not fixed and can be freely swung within a certain range. We will provide a long LED illuminant LED that has been improved.

The present invention is a surface-emitting LED module in which a board-mounted LED is housed in a housing made of a flexible material having a substantially rectangular cross section. The present invention relates to a long LED light emitter in which a board-mounted LED that is not fixed to the housing is housed in a swinging space surrounded by an inner wall of a housing and a regulation convex portion.

Further, the light rays emitted from the plurality of LEDs mounted on the board in the housing are characterized in that the LEDs mounted on the board are configured to be swingable so as to be diffusely reflected toward the inner wall surface of the housing.

In addition, the outer wall of the housing has a black color, and the inner wall surface has a white or milky white color to diffuse the directionality of the LED light, thereby reducing the transmittance of the LED light to the outside of the housing and allowing the LED light to flow. It is characterized by being configured so as not to leak to the outside as much as possible.

In addition, a reinforcing plate is attached to the LED-compatible part on the back surface of the LED mounting board.

In addition, a cap is attached to the end of the long housing having a substantially rectangular cross section, and the cap is composed of a lid that closes the opening of the housing and a cap body that protrudes from the back of the lid. , The cap body is configured so that it can be closely fixed to the inner wall of the housing opening by unevenly fitting with the inner wall of the housing opening, and the housing and the cap body are integrated by a fixing pin inserted from the outside of the wall body of the housing. It is characterized by being fixed.

In addition, an injection port for injecting the adhesive is formed on the side surface of the lid of the cap, and the injection port is provided on the outer surface of the cap body so as to communicate with a large number of slits and the adhesive is injected from the injection port through the slit. It is characterized in that it is configured to penetrate into the joint between the cap body and the inner wall of the housing opening by a capillary function.

According to the first aspect of the present invention, in a surface emitting LED module in which a substrate-mounted LED is housed in a housing made of a flexible material having a substantially rectangular cross section, a regulation convex portion is provided inside the housing so as to face each other. By storing the board-mounted LED that is not fixed inside the housing in the swinging space surrounded by the inner wall of the housing and the regulation convex part, the board-mounted LED can be freely displaced in the swinging space. It will fulfill the various functions described below, and it will be possible to irradiate the LED light emission in a complicated manner to improve the light emission function of the surroundings, and it will be easy to bend when mounting the housing and it will be mounted reliably. Has the effect of being able to.

Moreover, the housing is configured to be long and flexible, for example, an elastomer resin is used as the material. As a result, when the LED light emitter according to the present invention is mounted and mounted at a curved surface position such as a dashboard of an automobile or a position where the outer diameter has an uneven shape or a curved shape such as a bonnet edge, the housing is mounted. It will be bent according to the uneven shape of the outer shape provided by. By performing such bending mounting, the housing between the LEDs mounted by light scattering at regular intervals is also deformed.

In this way, when the housing is deformed together with the built-in board or independently, the LED mounted on the board swings in the swing space of the housing so as to direct the direction according to the deformation of the housing. That is, the light emitting direction of the LED changes in a complicated manner as the LED mounted on the board swings.

A feature of the present invention is that the factor that causes the light emitting direction of the LED to change in a complicated manner is that the LED swings due to the deformation of the housing. Moreover, the complex directivity of such LED light emitters is enhanced between adjacent LEDs arranged on the substrate at regular intervals. That is, the light emission of the adjacent LEDs is complicatedly overlapped by the fluctuation, so that the light emitting layer is also formed between the adjacent LEDs. The light emitting layer formed between the adjacent LEDs eliminates the original situation where the position of the scattered LED emits point light and the light emission illumination between the LEDs decreases, and the space between the LED light emitting points and the LEDs It also has the effect of uniformly generating a constant amount of light and emitting surface light from the light emitting surface of the housing, which is the lighting window.

Further, the housing and the base material made of a flexible material are flexibly deformed and mounted according to the outer shape of the object to be mounted, and the LED mounting board is mounted on the inner wall surface in the swing space provided by the housing. However, it will swing. As described above, the structure in which the LED mounting board can swing inside the housing can prevent the member from being damaged due to the difference in the heat shrinkage rate between the LED mounting board and the housing. Since the heat shrinkage rate differs depending on the material constituting the member, when members made of different materials are connected, a decrease in durability due to thermal stress generated between the members has been regarded as a problem. That is, by arranging the LED mounting board and the housing independently, the influence of the difference in heat shrinkage can be avoided, and high durability against heat can be provided.

Further, according to the invention of claim 2, the light rays emitted from the plurality of LEDs mounted on the board in the housing are diffusely reflected toward the inner wall surface of the housing by oscillating the LEDs mounted on the board. Due to the configuration, the light emitted from the swingable board-mounted LED does not concentrate on one point, and in particular, it does not concentrate on the diffuser plate that becomes the LED irradiation window formed on one surface of the housing. It has the effect of increasing the illuminance by reflecting and diffusing in all directions and improving the lighting efficiency.

Further, according to the invention of claim 3, since the outer peripheral wall of the housing is colored in black and the inner wall surface is colored in white or milky white, the LED light is easily diffusely reflected inside the housing. Since the outer wall of the housing is a black color, it prevents LED light from leaking to the outside of the housing as much as possible and increases the degree of light irradiation from the diffuser plate of the housing to further improve the lighting efficiency. There is an effect that can be done.

Further, according to the invention of claim 4, by attaching a reinforcing plate to the portion corresponding to the LED on the back surface of the LED mounting board, it is possible to prevent the risk of the LED peeling off from the board even if the board is bent. There is an effect that can be done.

Further, according to the invention of claim 5, a cap is attached to the end of the long housing having a substantially rectangular cross section, and the cap is attached to the lid portion that closes the housing opening and the back surface of the lid portion. The cap body is composed of a protruding cap body, and the housing and the cap body are integrally fixed by a fixing pin inserted from the outside of the wall body of the housing, so that the cap and the housing opening are securely attached. There is an effect that the adhesive can penetrate the joint surface between the inner wall of the housing opening and the cap body and perform a more reliable adhesive function.

Further, according to the invention of claim 6, an injection port for injecting an adhesive is formed on the side surface of the lid portion of the cap, and the injection port is provided on the outer surface of the cap body so as to communicate with a large number of slits. Therefore, it penetrates into the joint between the cap body and the inner wall of the housing opening through the slit from the adhesive injection port, fulfills a tighter joint function, and makes the inside of the housing a complete shielding space from the atmosphere to protect the LED module. There is an effect that can be done.

The gist of the present invention is a surface-emitting LED module in which a substrate-mounted LED is housed in a housing made of a flexible material having a substantially rectangular cross section. It relates to the fact that the LED mounted on the board, which is not fixed inside the body, is housed in the swinging space surrounded by the inner wall of the housing and the regulation convex portion.

Further, the light rays emitted from the plurality of LEDs mounted on the board in the housing are characterized in that the LEDs mounted on the board are configured to be swingable so as to be diffusely reflected toward the inner wall surface of the housing.

In addition, the outer wall of the housing has a black color, and the inner wall surface has a white or milky white color to diffuse the directionality of the LED light, thereby reducing the transmittance of the LED light to the outside of the housing and allowing the LED light to flow. It is characterized by being configured so as not to leak to the outside as much as possible.

In addition, a reinforcing plate is attached to the LED-compatible part on the back surface of the LED mounting board.

In addition, a cap is attached to the end of the long housing having a substantially rectangular cross section, and the cap is composed of a lid that closes the opening of the housing and a cap body that protrudes from the back of the lid. , The cap body is configured so that it can be closely fixed to the inner wall of the housing opening by unevenly fitting with the inner wall of the housing opening, and the housing and the cap body are integrated by a fixing pin inserted from the outside of the wall body of the housing. It is characterized by being fixed.

Examples of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram of the long LED light emitter 1 of the present invention.

As shown in FIG. 2, the long LED light emitter 1 of the present invention constitutes a surface emitting LED module 20 in which an LED 22 mounted on a substrate 21 is housed in a housing 10 having a substantially rectangular cross section. The housing 10 has a substantially rectangular hollow cross section and is formed of a long resin with a resin. The outer surface 10a is made of a milky white diffusion plate 11 made of a styrene-based elastomer resin, and the other three surfaces 10b are black olephine-based elastomers. The color of the outside made of resin prevents the LED light inside the housing from leaking to the outside of the housing as much as possible, and the light is diffused to increase the illumination.

On the hollow inner side surface of the housing 10, a reflective portion 12 made of a white styrene-based elastomer resin having a constant wall thickness is formed on three sides 10b excluding the diffusion plate 11 (one side 10a side constituting the housing 10). ..

Moreover, as shown in FIG. 2, on the hollow inner side surface of the housing 10, the regulating convex portions 13 are projected from the diffuser plate 11 and the facing inner wall surface 10b'while maintaining a constant interval while facing each other. The regulated convex portion 13 is made of a styrene-based elastomer resin that forms the inner wall of the housing.

Moreover, as shown in FIG. 2, the space portion of the majority portion formed by the regulation convex portion 13 in the housing 10 forms a swing space 14 in which the LED 22 mounted on the substrate 21 is housed.

In this way, the LED 22 mounted on the board 21 is housed in the swing space 14 inside the housing 10, and the width W1 of the board 21 is narrower than the internal width W2 of the housing 10 and is opposed to the tip of the regulation convex portion 13. It is formed wider than the interval W3, and the LED mounted on the board is configured to be swingably movable without being fixed in the swing space by the comparative formation of the width. That is, the width W1 of the LED 22 mounted on the substrate 21 is formed so that W3 <W1 <W2.

Therefore, due to such a configuration, the LED 22 mounted on the substrate 21 is placed on the bottom portion 10c of the housing 10 in the posture in which the diffusion plate 11 is located laterally, and the LED light emitting surface 22a faces the ceiling surface 10d of the housing 10. It becomes a posture to do.

In this posture, as shown in FIG. 3, the light from the LED 22 is directed toward the left and right inner surfaces and the ceiling surface of the housing 10, and is reflected by the left and right inner surfaces and the ceiling surface to be reflected in the housing 10. It diffusely reflects and is finally condensed in the direction of the diffuser plate 11 and transmitted through the diffuser plate 11 to illuminate the outside of the housing 10. In FIG. 3, the white arrow whose base end is near the LED light emitting surface 22a indicates the light emitted from the LED light emitting surface 22a, and the white arrow whose base end is near the reflecting portion 12 is diffusely reflected by the reflecting portion 12. Shows the light.

That is, by diffusing the directivity of the LED light, the transmittance of the LED light to the outside of the housing 10 is lowered so that the LED light does not leak to the outside as much as possible. Further, by attaching a reinforcing plate 23 to the portion corresponding to the LED on the back surface 20a of the LED module 20 that emits light from the surface, it is possible to prevent the LED 22 from peeling off from the substrate 21 despite the bending of the substrate 21.

Further, as shown in FIGS. 10A and 10B, the substrates 21 and 21'of a certain length constitute an LED module 20 that emits surface light from a long object through a pattern connected in series. For example, the ends of the LED substrate 21 are stacked one above the other and bonded to each other via the preliminary solder 24. In the figure, reference numerals 25 (25a, 25b) indicate a joining pattern between the ends of the substrates 21, 21'to be joined. 10 (a) is a plan view showing the vicinity of the ends of the two substrates 21 and 21'to be joined, and FIG. 10 (b) is a diagram for laterally explaining the structure of FIG. 10 (a). be.

The joining pattern between the ends of the substrates 21 and 21'will be specifically described. The end portion of the LED substrate 21 and the end portion of the LED substrate 21'are overlapped with each other as shown in FIG. A strip-shaped jumper 26 having an opening in a substantially middle portion is attached to the upper portion of the two stacked substrates 21, 21'. The LED 22 attached to the substrates 21 and 21'is exposed from the opening 26a of the jumper 26.

A pattern 25 (25a) is provided on the lower surface of the jumper 26 (the side facing the substrate 21 and 21'). A gap of approximately the thickness of the substrate 21 is formed between the jumper 26 and the substrate 21'. A preliminary solder 24 is provided to fill this gap. That is, the preliminary solder 24 is formed so as to connect the pattern 25 (25b) in the shape of the substrate 21'and the pattern 25 (25a).

It is assumed that a current is flowing from the substrate 21 to the substrate 21'. With such a structure, the current flows in the following path. That is, the current flows in the order of the substrate 21, the pattern 25a, the jumper 26, the preliminary solder 24, the pattern 25b, and the substrate 21'. As a result, the LED 22 mounted on the board 21 and the LED 22 mounted on the board 21'are emitted in conjunction with each other.

Therefore, the two substrates 21 and 21'connected by using the jumper 26 become a strongly integrated substrate. Further, since the LED 22 mounted on the end portion of the substrate 21 and the substrate 21'is not hidden by the jumper 26 due to the opening 26a provided in the jumper 26, the brightness is not lowered.

Since the end of the housing 10 is open (hereinafter referred to as the opening 15), the cap 30 is closely attached and fixed to the end of the long housing 10 in order to seal the inside of the housing 10. ing. That is, as shown in FIG. 5, the cap 30 projects into the lid portion 31 of the flat plate that closes the opening portion 15 of the housing 10 and the back surface 31a of the lid portion 31, and extends into the opening portion 15 at the end of the housing 10. It is composed of a rectangular cap body 32 that can be fitted.

The left and right side surfaces 32a of the rectangular cap body 32 are provided with notches 33 so as to be unevenly fitted with the left and right regulation convex portions 13 projecting from the inner wall of the opening 15 of the housing 10.

Further, as shown in FIG. 6, two pin holes 34 are formed on the ceiling surface 10d of the housing 10 on the left and right, and a pin is formed on the upper side surface 32b of the cap body 32 at a position corresponding to the pin hole 34. When the cap body 32 is fitted to the end opening portion 15 of the housing 10 by drilling the fitting hole 35, the fixing pin 36 is inserted from the pin hole 34 into the pin fitting hole 35 to lock the cap body 32. It is configured to fulfill.

As shown in FIGS. 7 and 8, slits 37 having a tooth-like shape for flowing the liquid adhesive are formed on the upper side surface 32b and the left and right side surfaces 32a of the cap body 32, and the cap 30 is formed. An external adhesive injection port 38 communicating with the slit 37 is notched on the ceiling surface 31b of the lid portion 31 of the above. If the liquid adhesive flows in from the external adhesive injection port 38, the adhesive penetrates the joint between the inner wall of the opening 15 of the housing 10 and the outer surface of the cap body 32 through the slit 37 by capillarity, and together with the adhesive. The cap 30 is tightly sealed to the opening 15 of the housing 10 via the integral fitting structure to improve the integrity, and there is an effect that the product of the long LED light emitter 1 can be permanently implemented.

As shown in FIGS. 7 and 8, an external adhesive injection port 38 for injecting an adhesive is formed on the side surface 30a of the lid portion 30a (ceiling surface 31b of the lid portion 31) of the cap 30, and the external adhesive is formed. The injection port 38 communicates with a large number of slits 37 provided on the outer surfaces (32a and 32b) of the cap body 32, so that the opening of the cap body 32 and the housing 10 is communicated from the external adhesive injection port 38 through the slit 37. The LED module 20 housed inside as a blocking space that invades the joint with the inner wall of 15 and fulfills a tighter bonding function and shields the inside of the housing 10 from the atmosphere is protected from external humidity, water leakage, and contaminants. ..

Further, since the outer shape of the housing 10 is rectangular as described above, when it is mounted on another product, it can be easily closely mounted by using the rectangular flat surface. Therefore, for example, an adhesive tape such as double-sided tape can be easily mounted. The housing can be attached to the flat surface portion of another product via.

Further, a harness 40 for connecting the LEDs 22 is wired inside the housing 10, and specifically, as shown in FIG. 9A, a buffer is provided inside the branch case 47 connected to the housing 10. The filler 41 is stored, and four harnesses 40 are regularly arranged vertically and horizontally inside the branch case 47. In the figure, reference numeral 42 indicates an insulator on the outer circumference of the harness, and reference numeral 43 indicates a conductor. 9 (a) is a diagram illustrating the structure of the branch case 47, FIG. 9 (b) is a cross-sectional view of the branch case 47, and FIG. 9 (c) shows the housing 10 and the branch case 47. It is a figure of the vicinity of the harness cap 46 which connects with.

When the harness 40 derived from the housing 10 is connected to the next adjacent housing 10', the harness styrene-based elastomer resin is wired on the extension line of the housing 10 as shown in FIG. 4A. However, if the diffuser plate 11 on the light emitting surface is mounted as the front exposed side, the harness 40 does not enter the set frame 44 and spoils the appearance. Therefore, the problem is solved by wiring on the opposite side of the diffuser plate 11. However, for that purpose, a lead-out hole 45 for leading out the harness must be formed on the wall surface of the housing 10 (on the side of the housing 10b'), and the airtightness inside the housing 10 is impaired. Therefore, as shown in FIG. 4B, a branch case 47 is branched and connected to the harness cap 46 attached to the end of the housing 10, and the harness 40 is routed from the lid portion 48 of the harness cap 46 to route the harness 40. It is configured to ensure the airtightness inside the housing 10 together with the wiring.
