Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the embodiment of the invention discloses a light emitting assembly, which may be applied to a wearable device, and specifically may include a circuit board 100, a substrate 200, a first light emitting device 300, and a second light emitting device 400.
The circuit board 100 is used for controlling the state of the light emitting device, and the circuit board 100 is provided with a avoiding hole 110. Alternatively, when the light emitting assembly is applied to a wearable device, the circuit board 100 may be a main board of the wearable device. The substrate 200 is disposed on one side of the circuit board 100, and the substrate 200 is electrically connected to the circuit board 100, which may be a ceramic substrate. The substrate 200 has a first face 210 facing the escape hole 110, and a side face 220 connected to the first face 210. The first light emitting device 300 is disposed on the first surface 210 of the substrate 200, and the second light emitting device 400 is disposed on the side surface 220 of the substrate 200. Here, the functions of the first light emitting device 300 and the second light emitting device 400 may be the same or different. Optionally, the first light emitting device 300 may include at least one of a flash lamp, a fill light, a breathing light, and an effect light, and the second light emitting device 400 may include at least one of a flash lamp, a fill light, a breathing light, and an effect light, and of course, the first light emitting device 300 and the second light emitting device 400 may also be other devices capable of emitting light.
In the light emitting module, the first light emitting device 300 and the second light emitting device 400 share the same substrate 200, and compared with a mode that the first light emitting device 300 and the second light emitting device 400 are respectively provided with the substrate 200, the light emitting module disclosed in the embodiment of the present invention can omit one substrate 200. Therefore, the space occupied by the whole light emitting assembly is smaller. When the light emitting assembly is applied to a wearable device, the thickness of the wearable device is reduced. Of course, the cost of the light emitting assembly is also reduced when the first light emitting device 300 and the second light emitting device 400 share the same substrate 200.
Further, at least a portion of the first light emitting device 300 may be located in the avoiding hole 110, at this time, the avoiding hole 110 may avoid the first light emitting device 300, and the first light emitting device 300 may be disposed by using the space occupied by the circuit board 100, so that the extra occupied space of the first light emitting device 300 is smaller, and the space occupied by the whole light emitting assembly is further reduced.
In an alternative embodiment, in order to facilitate the arrangement of the first light emitting device 300 and the second light emitting device 400, the circuit board 100 may include a circuit board main body 120 and a light bar 130, the circuit board main body 120 may serve as a main board of the wearable device, the light bar 130 is disposed on the circuit board main body 120, and the two are electrically connected, the substrate 200 is disposed on a side of the light bar 130 away from the circuit board main body 120, and the avoiding hole 110 penetrates through the circuit board main body 120 and the light bar 130.
Further, the avoiding hole 110 may specifically include a first hole section 121 and a second hole section 131, the circuit board main body 120 is provided with the first hole section 121, the light bar 130 is provided with the second hole section 131, and a part of the first light emitting device 300 is located in the first hole section 121, and another part is located in the second hole section 131. In other words, the first light emitting device 300 is entirely located in the avoiding hole 110, and therefore the first light emitting device 300 does not occupy additional space, so that the space occupied by the whole light emitting assembly is smaller. Meanwhile, when the light emitting assembly receives an external force, the external force is basically borne by the circuit board 100 and the substrate 200, and does not directly act on the first light emitting device 300 and the second light emitting device 400, so that the first light emitting device 300 and the second light emitting device 400 are not easily damaged by the external force, thereby improving the reliability of the light emitting assembly and prolonging the service life thereof.
Alternatively, the shapes and sizes of the first hole segment 121 and the second hole segment 131 may be different, but such an arrangement may result in a situation where space is wasted in the first hole segment 121 or the second hole segment 131, and may also affect the structural strength of the circuit board 100. Therefore, in a direction perpendicular to the circuit board 100, a projected contour of the first hole section 121 coincides with a projected contour of the second hole section 131. At this time, the first hole segment 121 and the second hole segment 131 have the same shape and substantially the same size, so that the first light emitting device 300 can be sufficiently disposed in the space inside the whole avoiding hole 110, thereby making full use of the space inside the avoiding hole 110, and the first hole segment 121 and the second hole segment 131 have the smallest size, thereby improving the structural strength of the circuit board 100. In order to simplify the process of manufacturing the circuit board 100, the first and second hole sections 121 and 131 may be circular, square, or the like in shape.
In an alternative embodiment, both the first and second light emitting devices 300 and 400 may be provided as one. In other embodiments, the number of the first light emitting devices 300 may be multiple, and the multiple first light emitting devices 300 are arranged at intervals along the extending direction of the light bar 130. Specifically, the extending direction of the light bar 130 may be parallel to the first face 210. After the number of the first light emitting devices 300 is increased, the first light emitting devices 300 can emit light together, so that the light emitting amount is increased, and the light emitting requirement is better met. Similarly, the number of the second light emitting devices 400 may be multiple, and the multiple second light emitting devices 400 are arranged at intervals along the extending direction of the light bar 130. Further, the first light emitting devices 300 may be uniformly spaced along the extending direction of the light bar 130, and the second light emitting devices 400 may be uniformly spaced along the extending direction of the light bar 130, so as to achieve a better light emitting effect.
In order to realize the electrical connection between the substrate 200 and the circuit board 100, in one embodiment, the side 220 of the substrate 200 may be provided with a first pad, and the circuit board 100 is provided with a second pad, and the first pad is electrically connected to the second pad through the board-to-board connector 500. When the connection mode is adopted, the positions of the first bonding pad and the second bonding pad are relatively flexible, so that the structural design of the light-emitting component is simpler, and the processing cost is lower. In another embodiment, the first surface 210 of the substrate 200 is provided with a first bonding pad, and the circuit board 100 is provided with a second bonding pad, and the first bonding pad and the second bonding pad are welded. When the connection mode is adopted, the first bonding pad and the second bonding pad are directly welded, and the electric connection between the substrate 200 and the circuit board 100 is realized without the board-to-board connector 500, so that the number of parts contained in the light-emitting assembly is less, and the cost is lower.
When the circuit board 100 includes the circuit board main body 120 and the light bar 130, the second pads may be disposed on the circuit board main body 120, so that the substrate 200 may be directly electrically connected to the circuit board main body 120; the second bonding pads may also be disposed on the light bar 130, so that the substrate 200 is directly electrically connected to the light bar 130. The two setting modes can be flexibly selected according to actual conditions, and the two setting modes are not limited in the text.
In an alternative embodiment, in order to simplify the structures of the first and second light emitting devices 300 and 400, the first and second light emitting devices 300 and 400 each include a light emitting chip and a light emitting material, the light emitting chip is disposed on the substrate 200, and the light emitting material wraps the light emitting chip. Specifically, the first light emitting device 300 includes a first light emitting chip 310 and a first light emitting material 320, the second light emitting device 400 includes a second light emitting chip 410 and a second light emitting material 420, the first light emitting chip 310 is disposed on the first surface 210 of the substrate 200, the second light emitting chip 410 is disposed on the side surface 220 of the substrate 200, the first light emitting chip 310 is wrapped by the first light emitting material 320, and the second light emitting chip 410 is wrapped by the second light emitting material 420.
The embodiment of the invention also discloses wearable equipment, which comprises an equipment main body 600 and a connecting band 700 connected with the equipment main body 600, wherein the equipment main body 600 is provided with the light-emitting component in any embodiment. The light emitting module can omit a substrate 200, and further, the first light emitting device 300 can utilize the space occupied by the circuit board 100, so that the additional space occupied by the first light emitting device 300 is smaller. Thus, the whole light emitting assembly occupies less space, so that the thickness of the wearable device is reduced. Meanwhile, the first light emitting device 300 and the second light emitting device 400 share the same substrate 200, so that the wearable device has low cost.
Further, the apparatus main body 600 may be provided with a display module 800, the display module 800 is disposed on one side of the circuit board 100, and the second light emitting device 400 is a backlight source of the display module 800. Specifically, the display module 800 may include a display screen 810 and a cover plate 820, the display screen 810 is disposed in the apparatus body 600, the cover plate 820 is connected to the apparatus body 600, and the cover plate 820 covers the display screen 810, thereby protecting the display screen 810. The display screen 810 may be positioned at one side of the substrate 200 with the second light emitting device 400 facing the display screen 810, and light emitted from the second light emitting device 400 may enter the display screen 810, thereby allowing the display screen 810 to display. After the arrangement, a backlight source does not need to be separately arranged in the device body 600 corresponding to the display screen 810, so that the structure of the wearable device is simplified.
The apparatus body 600 has a back surface facing away from the display module 800, the first surface 210 of the substrate 200 faces the back surface, the back surface is provided with a through hole, the first light emitting device 300 is opposite to the through hole, and the first light emitting device 300 may be a flash lamp. That is, light emitted from the first light emitting device 300 may enter the external environment through the through hole. Optionally, at this time, the first light emitting device 300 may be used to complete detection items such as heart rate detection, so that the wearable device can meet the requirement of the user for monitoring the physical condition.
