Description

Embodiments of the present invention relate to light emitting modules.

In recent years, translucent display devices having translucency have been developed. In such a transmissive display device, for example, light-emitting modules extending in the horizontal direction are arranged apart from each other in the vertical direction. In each light-emitting module, a plurality of light-emitting devices are mounted on a horizontally extending bar-shaped substrate. Accordingly, by arranging a large number of light emitting devices in a plane and controlling each light emitting device, an image is displayed as a whole. In the transmissive display device, by arranging the light-emitting modules at intervals, both translucency and image display can be achieved. In addition, by arranging each light-emitting device so that it emits light in one direction, images can be seen from the light-emitting side but not from the non-light-emitting side, achieving bi-directional translucency. However, the image can be displayed only in one direction.

For example, if a translucent display device is installed inside the window of a store and an image is displayed facing outside, the image can be superimposed on the scenery inside the store from outside the store, and only the outside scenery can be seen from inside the store. can be seen. In the light-transmitting display device, it is preferable that the area of the light-emitting device is small when viewed from the non-light-emitting side, for example, from inside the room, in order to ensure high light-transmitting properties.

The first light emitting element 41 is, for example, a light emitting diode (LED). The first light emitting element 41 is mounted on the first inner lead portion 21a, and is arranged with the main light emitting surface facing the first surface 30a. The first light emitting element 41 is connected to the first inner lead portion 21a via the first wire 38 and is connected to the second inner lead portion 22a via the second wire 39 . When a light-emitting element having a pair of electrodes on its upper and lower surfaces is used as the first light-emitting element 41, the lower-surface electrode can be electrically connected to the first inner lead portion 21a via a conductive bonding member. .

A side wall 34 is provided on the first surface 30 a of the resin member 30 so as to surround the translucent layer 33 . The side walls 34 can be made of, for example, white resin. As a result, the light emitted from the first light emitting element 41 passes through the light-transmitting layer 33 , is partly reflected by the side wall 34 , and is emitted through the first surface 30 a of the resin member 30 . Further, the outer surface of the side wall 34 may be covered with a dark-colored covering member, or the entire side wall 34 may be formed of a dark-colored resin material. Thereby, light leakage from the side wall 34 can be suppressed. Schematically speaking, the first portion 31 of the resin member 30 includes sidewalls 34 and the second portion 32 includes the translucent layer 33 and sidewalls 34 . For convenience of illustration, the transparent layer 33 is omitted in FIG. 2A.

Next, the effects of this embodiment will be described.
In the light-emitting module 1 according to this embodiment, the light-emitting device 20 is provided from the main surface 10a of the substrate 10 to the end surface 10b. As a result, part of the first surface 30a, which is the light emitting surface of the light emitting device 20, can be arranged on the end surface 10b, and the first surface 30a can be extended below the main surface 10a. As a result, the light emitting surface can be widened while the height of the light emitting device 20 on the main surface 10a of the substrate 10 is suppressed. In other words, when viewed from the light emitting side of the light emitting module 1 , that is, from the side of the end surface 10 b of the substrate 10 , the light emitting device 20 can be arranged so that a portion of the light emitting device 20 overlaps the substrate 10 . As a result, in the transmissive display device 100 using the light emitting module 1, translucency in the width direction W can be improved.

In addition, since the first surface 30a can extend below the main surface 10a of the substrate 10, the inner surface of the side wall 34 with respect to the main surface 10a, which is the mounting surface of the light emitting device 20, is below the main surface 10a. can be made larger. As a result, the light emitted from the first light emitting element 41 is distributed to a lower angle, and the light distribution in the upward direction when viewed from the light emitting side can be widened. Such a light-emitting module 1 is particularly effective in a transmissive display device installed on a window surface of a building, which is often viewed from below.

Furthermore, in the light-emitting module 1 , the first outer lead portion 21 b and the second outer lead portion 22 b are connected to the terminals of the substrate 10 on the main surface 10 a of the substrate 10 . Therefore, by arranging the solder on the terminal with the main surface 10a facing upward and placing the light emitting device 20 thereon, the plurality of light emitting devices 20 can be collectively mounted on the substrate 10 by reflow. can. At this time, by bringing the sixth surface 30f of the resin member 30 into contact with the end surface 10b of the substrate 10, the light-emitting device 20 is prevented from shifting in the width direction W, and the position of the light-emitting device 20 relative to the substrate 10 is accurately determined. can do.

A group may be formed for each of the plurality of light emitting devices 20, and the plurality of light emitting devices 20 belonging to each group may emit lights of different colors. For example, a pixel may be configured by forming a set of the light emitting device 20 that emits red light, the light emitting device 20 that emits green light, and the light emitting device 20 that emits blue light. In this case, the color of the light emitted by the first light emitting element 41 may be different between the light emitting devices 20 belonging to each group. The types may be different. This also allows the translucent display device 100 as a whole to display a color image.

Light emitted from the first light-emitting element 41 , light emitted from the second light-emitting element 42 , and light emitted from the third light-emitting element 43 are transmitted through the translucent layer 33 and partially reflected by the side wall 34 . , through the first surface 30 a of the resin member 30 .

Next, the effects of this embodiment will be described.
Since the light-emitting module 3 according to this embodiment is provided with the first protection element 46 and the second protection element 47, the reliability is high. Moreover, since the first light emitting element 41, the second light emitting element 42, and the third light emitting element 43 are arranged in a triangular shape, the length of the light emitting device 70 in the longitudinal direction L can be shortened. Furthermore, since the anodes and cathodes of the first light emitting element 41, the second light emitting element 42, and the third light emitting element 43 can be controlled independently of each other, the degree of freedom in driving is high. The configuration and effects of this embodiment other than those described above are the same as those of the second embodiment.

In the first embodiment, an example in which each light emitting device is provided with one light emitting element is shown, and in the second and third embodiments, an example in which each light emitting device is provided with three light emitting elements is shown. , but not limited to. Each light-emitting device may be provided with two or four or more light-emitting elements. Further, in each of the above-described embodiments, an example in which the longitudinal direction L of the substrate 10 is horizontal has been shown, but the present invention is not limited to this, and the longitudinal direction L may be a vertical direction or an oblique direction. may However, when the light-emitting device is bonded to the substrate 10 by reflow in the manufacturing process of the light-emitting module, it is preferable that the main surface 10a of the substrate 10 faces upward. Furthermore, in each of the above-described embodiments, an example in which the light-emitting module is used in a transmissive display device is shown, but the present invention is not limited to this, and may be used in, for example, a translucent lighting device.

INDUSTRIAL APPLICABILITY The present invention can be used, for example, in translucent display devices, translucent lighting devices, and the like.
