Abstract
Description
Technical Field
[0001] The present invention relates to an attachment structure of an LED lens that attaches an LED lens for guiding the light of an LED mounted on a substrate in a display unit to the outside to the display unit.
Background Art
[0002] In a telephone or the like, a light emitting unit may be provided to notify the user of the state of the telephone by lighting or blinking during an incoming call, an outgoing call, or a hold state. This light emitting unit is constituted by an LED lens for guiding the light source of an LED mounted on a substrate to the outside (see, for example, Patent Document 1). The LED lens described in this Patent Document 1 is provided in a handset of a cordless telephone. Inside the case of this handset and at the upper center of the back surface, a pair of lens support walls extending in the longitudinal direction of the handset are provided. A hole that opens toward the outside of the case is formed in a portion between these walls of the case.
[0003] The LED lens is formed in a plate shape that can be inserted between a pair of lens support walls. A shaft protruding from both surfaces of the LED lens is provided at one end of the LED lens. On the other hand, an engagement protrusion is provided at the other end of the LED lens. The shaft of the LED lens is inserted into a groove-shaped recess formed in the lens support wall. The engagement protrusion is locked to a holding piece provided on the case.
[0004] This LED lens is fixed to the case by engaging the shaft with the recess of the lens support wall and rotating the LED lens about the shaft in that state to lock the engagement protrusion to the holding piece of the case. The case is formed by an upper case having an LED lens and a lower case that closes the opening of the upper case. A substrate having an LED that irradiates the LED lens with light is attached to the lower case. In the LED lens mounting structure described in Patent Document 1, the LED lens is attached to the case through a series of steps, each with a different operation, which involves inserting the LED lens between a pair of lens-supporting walls of the case, rotating it, and engaging the engaging projection of the LED lens with a retaining piece of the case.

[0005] [Patent Document 1] Japanese Patent Publication No. 2005-223044 [Overview of the project] [Problems that the invention aims to solve]
[0006] The LED lens mounting structure shown in Patent Document 1 has the problem of poor workability because it requires multiple steps with different procedures to mount the LED lens. Furthermore, since the light from the LEDs mounted on the circuit board enters the LED lens directly and is then projected outwards, adjusting the brightness requires changing the voltage applied to the LEDs. Changing this voltage requires replacing electronic components, which is not a simple task.
[0007] The first object of the present invention is to provide an LED lens mounting structure that allows the LED lens to be easily attached to a housing. The second object of the present invention is to realize an LED lens mounting structure that allows the brightness of the light emitted from the LED lens to the outside to be adjusted without changing the voltage applied to the LED. [Means for solving the problem]
[0008] To achieve this objective, the LED lens mounting structure according to the present invention comprises a display unit housing an LED, and an LED lens provided on the display unit for guiding the light of the LED to the outside of the display unit, wherein the display unit comprises a display unit body having the LED and a panel mounted on top of the panel mounting surface of the display unit body, wherein the display unit body has a lens housing portion that opens to the panel mounting surface and also opens outwards from the display unit and is formed to allow the light of the LED to enter, and an engaging portion that opens to the panel mounting surface and the side wall of the lens housing portion, wherein the LED lens has a light-receiving portion facing the LED and a light-emitting portion that is exposed to the outside of the display unit through the opening of the display unit body, and has a main body portion inserted into the lens housing portion and an arm portion that protrudes from the main body portion and engages with the engaging portion, and cooperates with the engaging portion to restrict the movement of the main body portion relative to the display unit body, wherein the LED lens is held in place by being sandwiched between the display unit body and the panel.
[0009] In the present invention, the LED lens mounting structure is provided on the corner portion of the display unit, and the engagement structure, which consists of the engaged portion of the display unit body and the arm portion of the LED lens, may be provided at two locations along the two sides of the display unit that constitute the corner portion.
[0010] In the present invention, in the mounting structure for the LED lens, the protruding end of the arm portion that protrudes from the main body portion is formed by a partially protruding projection, and the LED lens may be positioned in the direction of the protrusion of the arm portion by the projection contacting the engaged portion.
[0011] In the LED lens mounting structure of the present invention, the main body of the LED lens is formed such that a portion of the light from the LED travels toward the panel, and the reflected light reflected by the panel is also guided toward the light-emitting portion, and a layered reflective structure that affects light reflection may be provided between the panel and the main body.
[0012] In the LED lens mounting structure of the present invention, the reflective structure may be composed of paint attached to the panel. [Effects of the Invention]
[0013] According to the present invention, the LED lens is assembled to the display unit body by inserting the main body of the LED lens into the lens housing portion of the display unit body and engaging the arm portion of the LED lens with the engaging portion of the display unit body. Then, the LED lens is fixed to the display unit body by attaching the panel to the display unit body. Therefore, according to this embodiment, the LED lens can be fixed to the display unit by a simple operation of stacking multiple components, thus providing an LED lens mounting structure that allows the LED lens to be easily attached to the housing.
[0014] Furthermore, according to the invention, which includes a reflective structure between the main body of the LED lens and the panel, it becomes possible to change the amount of light that is reflected from the panel and enters the main body of the lens. Therefore, it is possible to realize an LED lens mounting structure that allows adjustment of the brightness of the light emitted from the LED lens to the outside without changing the voltage applied to the LED.

Embodiments for Carrying out the Invention
[0016] Hereinafter, an embodiment of the mounting structure of the LED lens according to the present invention will be described in detail with reference to FIGS. 1 to 14. In this embodiment, an example of applying the present invention to a display panel attached to a telephone is shown.
[0017] The display panel 1 shown in FIG. 1 is attached to a telephone main body (not shown) so as to be swingable with the lower end portion in FIG. 1 as a swing center, and is formed in a substantially plate shape as a whole. At the corner portion 1a of the swing end portion of the display panel 1 (the upper right corner portion in FIG. 1), an LED lens 2 is provided for lighting up when the telephone receives an incoming call, makes a call, or is on hold, etc., to notify the user of the state of the telephone. The LED lens 2 guides the light of the LED 3 housed in the display panel 1 to the outside of the display panel 1. In this embodiment, the display panel 1 corresponds to the "display unit" referred to in the present invention.
[0018] The display panel 1 is configured as a housing 6 including a display unit main body 4 having an LED 3 and a panel 5 fixed to the display unit main body 4 in an overlapping manner. The panel 5 is overlapped with the display unit main body 4 in the thickness direction of the display panel 1 having a plate shape. As shown in Figure 3, the display unit body 4 is formed by combining multiple parts. The parts that make up the display unit body 4 include the lower housing 11, which is shown at the very bottom in Figure 3, the liquid crystal display unit 12, which is shown above the lower housing 11, and the upper housing 13, which is shown above the liquid crystal display unit 12.
[0019] The lower housing 11 and the upper housing 13 are formed from plastic material colored in a predetermined color. The liquid crystal display unit 12 comprises a circuit board 14 and a liquid crystal panel 15, and is housed between the lower housing 11 and the upper housing 13. LEDs 3 that illuminate the LED lens 2 are mounted on the circuit board 14.
[0020] As shown in Figure 4, a rectangular through-hole 16 is formed in the center of the upper housing 13. This through-hole 16 is for viewing the liquid crystal panel 15. In addition, a hole 22 is formed in the upper right corner portion 13a of the upper housing 13, which constitutes part of the mounting structure 21 for the LED lens 2 according to the present invention. This hole 22 is for housing the LED lens 2, although details will be described later. The panel mounting surface 23 of the upper housing 13 facing the panel 5 is formed flat.
[0021] Panel 5 is made of a transparent plastic material and is attached to the panel mounting surface 23 of the upper housing 13 with adhesive tape 24 (see Figure 3). It is desirable to use adhesive tape 24 made of a material and color that allows light to pass through easily. In this embodiment, the back surface of panel 5 (the surface facing the upper housing 13) is painted with an opaque color, except for the portion facing the inside of the through-hole 16 for viewing the liquid crystal in the upper housing 13. The painted area on the back surface of panel 5 is the area shown by hatching in Figure 1. Therefore, the inside of the through-hole 16 for viewing the liquid crystal can be seen through panel 5 from the front side.
[0022] The paint 25 (see Figure 14) that adheres to the back surface of panel 5 through painting is of a color that affects light reflection. In Figure 14, the thickness of the paint 25 is depicted as thicker than it actually is in order to make it easier to understand. As for the color of the paint 25, a color that reflects light of a desired brightness is selected, such as gold, silver, black, white, or gray. In this embodiment, the painted area to which the paint 25 adheres corresponds to the "layered reflective structure that affects light reflection" as defined in the present invention. In addition to using the paint 25, this reflective structure can also be realized by sandwiching a film-like sheet between the LED lens 2 and panel 5, although this is not shown in the figures.
[0023] The hole 22 for housing the LED lens 2 in the upper housing 13 opens into the panel mounting surface 23 of the upper housing 13 and is formed by multiple functional parts. As shown in Figure 5, the multiple functional parts are a lens housing portion 26 including the corner portion 1a of the upper housing 13, and a first engaged portion 27 and a second engaged portion 28 connected to the lens housing portion 26. The corner portion 13a of the upper housing 13 is formed by a horizontal wall 31 and a vertical wall 32, which form two sides of the upper housing 13. As shown in Figure 6, a notch 33 is formed where these horizontal walls 31 and vertical walls 32 intersect, and which connects to the lens housing portion 26. Therefore, in addition to the panel mounting surface 23, the lens housing portion 26 opens outwards from the upper housing 13 with the notch 33 as its opening edge.
[0024] Because the lens housing portion 26 is formed in the upper housing 13, the substrate 14 located inside the display unit body 4 is exposed within the lens housing portion 26. Therefore, the lens housing portion 26 and the substrate 14 constitute a recess formed in the display unit body 4. The LED 3 on the substrate 14 is positioned so as to shine light toward the corner portion 13a of the upper housing 13, as indicated by the arrow in Figure 6. The light from this LED 3 enters the lens housing 26, passes through the lens housing 26, and is directed toward the corner portion 13a. When viewed from the direction opposite to the substrate 14, the light from the LED 3 spreads outwards toward the notch 33, and is also irradiated in a way that spreads outwards toward the main surface of the substrate 14.
[0025] As shown in Figure 6, the lens housing 26 is formed by being surrounded by a first side wall 34 extending parallel to the lateral wall 31 of the upper housing 13, a second side wall 35 extending parallel to the vertical wall 32 of the upper housing 13, and a part of the lateral wall 31 and a part of the vertical wall 32, including the corner portion 13a of the upper housing 13. A first engaging portion 27 opens in the first side wall 34, and a second engaging portion 28 opens in the second side wall 35. These first and second engaging portions 27 and 28 are for positioning the LED lens 2, which will be described later, in cooperation with the LED lens 2, and are provided at two locations along the two sides that constitute the corner portion 13a of the upper housing 13.
[0026] As shown in Figure 6, the first and second engaged portions 27 and 28 in this embodiment are composed of a through hole 36 that opens into the panel mounting surface 23 and penetrates the upper housing 13, and a plate piece 38 having a notch 37 that connects the through hole 36 to the lens housing portion 26. The plate piece 38 is part of the first and second side walls 34 and 35. Thus, the first and second engaged portions 27 and 28, having the through hole 36 and the notch 37, open into the panel mounting surface 23 and the first and second side walls 34 and 35 of the lens housing portion 26.
[0027] The LED lens 2 is formed into a predetermined shape from a transparent plastic material. As shown in Figures 7 to 10, the LED lens 2 has a main body portion 41 that is inserted into the lens housing portion 26 described above, a first arm portion 42 that is inserted into the first engaging portion 27 described above, and a second arm portion 43 that is inserted into the second engaging portion 28 described above. As shown in Figures 11 to 13, the main body 41 consists of a light-receiving section 44 housed between the panel 5 and the upper housing 13, and a light-emitting section 45 that protrudes and is exposed outside the upper housing 13 (outside the display panel 1) through a notch 33 (opening) in the upper housing 13. Figure 11 is a cross-sectional view taken along line XI-XI in Figure 10. Figure 12 is a cross-sectional view taken along line XII-XII in Figure 10. Figure 13 is a cross-sectional view taken along line XIII-XIII in Figure 10.
[0028] As shown in Figure 13, a light-receiving surface 46 is formed at one end of the light-receiving section 44 that is furthest from the corner portion 13a of the upper housing 13, and faces the LED 3. The light-receiving surface 46 is composed of the wall surface of a recessed portion 47, which is formed in a shape in which a part of the main body portion 41 is partially recessed. A part of the LED 3 is inserted into this recessed portion 47. Furthermore, the other end of the light-receiving section 44 that is close to the corner portion 13a of the upper housing 13 and faces the bottom of the lens housing 26, the back surface 48, is inclined so that it gradually moves away from the bottom of the lens housing 26 as it approaches the corner portion 13a. As a result, a reflective surface 49 is formed inside the other end of the light-receiving section 44, which is inclined so that it gradually moves closer to the panel 5 as it approaches the corner portion 13a. The reflective surface 49 extends into the light-emitting section 45, as shown in Figures 11 to 13.
[0029] Furthermore, the front surface 50 of the light-receiving section 44, opposite to the bottom of the lens housing section 26, is formed flat, as shown in Figures 7 and 8. The edges of the panel 5 are superimposed on this front surface 50 either directly or via adhesive tape 24, as shown in Figures 11 to 13. As shown in Figure 2, the light-emitting portion 45 is formed in a curved shape that follows the corner portion 1a of the display panel 1, and is configured to partially protrude from the outer edge of the display panel 1.
[0030] The first arm portion 42 and the second arm portion 43 are integrally formed with the main body portion 41 and protrude from the main body portion 41. As shown in Figures 8 and 9, the first arm portion 42 and the second arm portion 43 are each formed in an L-shape in cross-section and have a projection 51 that extends toward the bottom of the lens housing portion 26 at a position away from the main body portion 41. The end faces 52 of the first and second arms 42 and 43 that are opposite to the bottom of the lens housing portion 26 are formed to be on the same plane as the end face of the light-receiving portion 44.
[0031] As shown in Figures 11 and 12, the projection 51 is formed to be inserted into the through holes 36 of the first and second engaged portions 27 and 28 when the main body portion 41 of the LED lens 2 is inserted into the lens housing portion 26. When the projection 51 is inserted into the through-hole 36 of the first and second engaged portions 27 and 28, the first and second arms 42 and 43 engage with the first and second engaged portions 27 and 28. As a result, the first and second arms 42 and 43 cooperate with the first and second engaged portions 27 and 28 to restrict the movement of the main body 41 relative to the upper housing 13. Thus, the first arm 42 and the first engaged portion 27 constitute the first engagement structure 53 (see Figure 10), and the second arm 43 and the second engaged portion 28 constitute the second engagement structure 54. The first engagement structure 53 and the second engagement structure 54 are provided at two locations along two sides of the display panel 1 that constitute the corner portion 13a of the upper housing 13.
[0032] As shown in Figures 7 to 9, the protruding ends of the first and second arm portions 42 and 43, which are convex to the main body portion 41, are formed by partially protruding projections 55. In this embodiment, the projections 55 are formed to be ridges that extend along the projection 51. As shown in Figure 10, the projections 55 provided on the first arm portion 42 abut against the hole wall surface of the through hole 36 of the first engaged portion 27, thereby positioning the LED lens 2 in the protruding direction of the first arm portion 42 (a direction parallel to the direction in which the vertical wall 32 of the upper housing 13 extends).
[0033] Furthermore, the projection 55 provided on the second arm portion 43 contacts the wall surface of the through hole 36 of the second engaged portion 28, thereby positioning the LED lens 2 in the protruding direction of the second arm portion 43 (a direction parallel to the direction in which the side wall 31 of the upper housing 13 extends). By adopting this configuration of positioning with the projection 55, the positioning accuracy of the LED lens 2 can be easily improved. Here, we will explain why accuracy can be easily improved.
[0034] The LED lens 2 is molded using a mold (not shown). The part of the mold that molds the projection 55 is formed by recessing a portion of the part that molds the protruding piece 51. In other words, by processing the mold to increase the depth of the recess, the height of the molded projection 55 can be increased, allowing for adjustment of the position of the LED lens 2. If the projection 55 is not provided, it is necessary to adjust the position by changing the amount of protrusion of the protruding piece 51, and processing must be performed on the part of the mold that molds the protruding piece 51. The part that molds the protruding piece 51 is larger than the part that molds the projection 55. In other words, to improve the accuracy of the position of the LED lens 2, it is only necessary to process a recess that is smaller than the part that molds the protruding piece 51, making position adjustment easy.
[0035] To assemble the display panel 1 having the mounting structure 21 for the LED lens 2 configured in this way, first, the lower housing 11 and the upper housing 13 are combined so that the liquid crystal display unit 12 is housed inside the lower housing 11 and the upper housing 13. Then, the LED lens 2 is inserted into the hole 22 of the upper housing 13. At this time, the main body 41 of the LED lens 2 is inserted into the lens housing 26, and the first and second arms 42 and 43 are inserted into the first and second engaged parts 27 and 28. The insertion direction of the LED lens 2 is the same as the direction in which the panel 5 is superimposed on the upper housing 13. As the first and second arms 42 and 43 are inserted into the first and second engaged parts 27 and 28, the first and second engagement structures 53 and 54 are realized, and the LED lens 2 is positioned so that it cannot move relative to the display unit body 4.
[0036] Next, the panel 5 is attached to the display unit body 4 via adhesive tape 24. Once the panel 5 is attached to the display unit body 4, the LED lens 2 is sandwiched and held in place by the display unit body 4 and the panel 5. Therefore, according to this embodiment, the LED lens 2 can be fixed to the display panel 1 by a simple operation of stacking multiple components, thus providing an LED lens mounting structure that allows the LED lens 2 to be easily attached to the housing 6 (display panel 1).
[0037] With the LED lens 2 attached to the display panel 1 by this mounting structure 21, when the LED 3 is lit, the light from the LED 3 enters the LED lens 2 from the light-receiving surface 46 as shown by the arrow in Figure 13. A portion of the light from the LED 3 crosses the light-receiving part 44 of the LED lens 2 and exits the LED lens 2 from the light-emitting part 45. Of the light from the LED 3, the light that hits the reflective surface 49 of the LED lens 2 and is reflected becomes reflected light and heads towards the light-emitting part 45.
[0038] Furthermore, of the light from LED3, the light that travels from the light-receiving unit 44 towards panel 5 mainly strikes the painted surface of panel 5, which is covered with paint 25, as indicated by arrow A in Figure 14. This light is reflected from the painted surface of panel 5 and re-enters the LED lens 2 as reflected light, as indicated by arrow B. The amount of reflected light reflected from panel 5 is determined by the color of the paint 25; it does not increase but decreases depending on the color. This reflected light has less light intensity than the light from LED3 that shines on the painted surface, and is further reflected by the reflective surface 49 and either travels towards the light-emitting unit 45 or travels directly to the light-emitting unit 45 and exits the LED lens 2 along with other light.
[0039] Therefore, by changing the color of the paint 25, it becomes possible to change the amount and brightness of reflected light returning from the panel 5 to the LED lens 2. If the amount of light lost when reflected from the painted surface decreases, the brightness of the LED lens 2 will increase. Therefore, according to this embodiment, it is possible to realize an LED lens mounting structure that allows the brightness of the light emitted from the LED lens 2 to the outside to be adjusted without changing the voltage applied to the LED.
[0040] In this embodiment, the LED lens 2 is provided on the corner portion 1a of the display panel 1. The first and second engagement structures 53 and 54, which consist of the first and second engaged portions 27 and 28 of the upper housing 13 and the first and second arm portions 42 and 43 of the LED lens 2, are provided at two locations along the two sides of the display panel 1 that constitute the corner portion 1a. Therefore, the movement of the LED lens 2 in two directions can be restricted by the first and second engagement structures 53 and 54, so that the LED lens 2 can be fixed so as not to move relative to the display panel 1, even though a simple mounting structure 21 is employed.
[0041] In this embodiment, the protruding ends of the first and second arms 42 and 43 of the LED lens 2 are formed by partially protruding projections 55. These projections 55 contact the hole walls of the first and second engaged portions 27 and 28, thereby positioning the LED lens 2 in the direction of protrusion of the first and second arms 42 and 43. Therefore, compared to the case where the position of the LED lens 2 is defined by the entire protruding ends of the first and second arms 42 and 43, it is possible to narrow the area of the mold that needs to be processed when adjusting the position of the LED lens 2, thus easily increasing the positioning accuracy of the LED lens 2.
[0042] In this embodiment, the main body 41 of the LED lens 2 is formed so that a portion of the light from the LED 3 travels toward the panel 5, and the reflected light reflected from the panel 5 is also guided toward the light-emitting part 45. A paint 25 (layered reflective structure) that affects light reflection is provided between the panel 5 and the main body 41. Therefore, the amount of light emitted by the LED lens 2 can be changed at a lower cost compared to changing the voltage applied to the LED 3.
[0043] In this embodiment, the layered reflective structure that affects light reflection is composed of paint 25 attached to the panel 5. Therefore, this reflective structure can be easily realized, and the brightness can be easily changed simply by changing the color. [Explanation of symbols]
