As shown in fig. 1 to 5, the light emitting assembly 100 of the present invention includes a housing 10, a light guide plate 20, a light emitting module 30 and a light reflecting portion 40.
The housing 10 serves as an external component of the light emitting module 100, and supports and protects internal components. The housing 10 is provided with a light exit hole 13, and in the length direction of the light exit hole 13, the width of the light exit hole 13 gradually decreases from the middle portion to the two end portions, respectively, to form a gradual change structure with a wide middle portion and narrow ends. The light exit opening 13 may, for example, substantially take the shape of a "fish-belly". Specifically, the casing 10 may be substantially rectangular, and includes a front casing 11, the front casing 11 is used for supporting the display screen 50 and has a bottom wall facing the back surface of the display screen 50 and a lower side plate 14 facing the lower side surface of the display screen 50. A light exit hole 13 may be formed in the length direction of the lower side plate 14, so that the light exit hole 13 is located below the display screen 50 to form downward light exit. However, the light exit hole 13 is not limited to this, and the light exit hole 13 may be provided above and/or on the side of the display screen 50 to form upward light exit and/or side light exit, or the light exit hole 13 may be provided above, below, or on the side. For example, the front housing 11 may include an upper side plate or left and right side plates, and the light outlet 13 is opened on the upper side plate and/or the left and right side plates. The shape of the housing 10 is not limited to a rectangular shape, and may be, for example, a circular shape or an elliptical shape, and when the housing 10 is a circular shape, the light exit hole 13 extends in the circumferential direction of the circular housing 10 to form a tapered strip-shaped hole having a wide middle and narrow ends. The display screen 50 may be a display screen with a touch function.
The light guide plate 20 is disposed in the housing 10, and a light exit surface 22 of the light guide plate 20 is opposite to the light exit hole 13. The light emitting module 30 is disposed in the housing 10, and a light emitting surface 301 of the light emitting module 30 faces the light incident surface 21 of the light guide plate 20. The light emitted from the light emitting module 30 enters from the light incident surface 21 of the light guide plate 20, and is guided by the light guide plate 20 to exit from the light exiting surface of the light guide plate 20. The light guide plate 20 guides the light emitted from the light emitting module 30, so that most of the dispersed light emitted from the light emitting module 30 is emitted toward the light exit hole 13, thereby increasing the amount of light exiting from the light exit hole 13.
Further, the shape of the light emitting surface 22 of the light guide plate 20 is adapted to the shape of the light emitting hole 13, wherein the width of the light emitting surface 22 of the light guide plate 20 gradually decreases from the middle portion to the two end portions in the length direction of the light guide plate 20, for example, the light emitting surface may also be in a shape of "fish maw". The strip-shaped gradually-changing light guide plate 20 matched with the light outlet 13 enables the light emitted from the light emitting surface 22 to be positioned in the light outlet 13, so that the light guide efficiency and the light emitting amount of the light outlet are improved.
The light reflecting portion 40 is located on the housing 10 and faces the light outlet 13, and is used for forming diffuse reflection on the light emitted from the light outlet to reduce discomfort caused by direct light. The light reflecting portion 40 may be a light reflecting member, such as a light reflecting plate, independent of the housing 10. The light reflecting portion 40 may also be a light reflecting member, such as a light reflecting surface, formed on the housing 10 as a part of the housing 10. Specifically, the housing 10 further includes a rear case 12, and the rear case 12 is disposed on the front case 11 to form a receiving space for receiving components such as the light guide plate 20 and the light emitting module 30. A portion of the rear case 12 is located below the front case 11. For example, the lower end of the rear housing 12 extends downward and forward and is located below the front housing 11, and a separate light reflecting plate facing the light exit hole 13 may be provided as a light reflecting member at the lower end of the rear housing 12, and may also serve as a decoration. Instead of providing a reflector, the upper surface of the lower end of the rear housing 12 facing the light exit hole 13 may be used as a reflector to diffuse the light emitted from the light exit hole through the upper surface, thereby reducing discomfort caused by direct light.
The utility model discloses an incident light that light guide plate 20 sent luminescence module 30 leads the light, lead-in the strip light-emitting hole 13 of gradual change formula to casing 10 on with the incident light, the light that jets out from light-emitting hole 13 is via the diffuse reflection of reflector portion 40 after, make light-emitting component 100 demonstrate by the centre gradually to both ends gradual change until the gradual change effect that disappears (the centre goes out the light volume many, both ends go out the light volume few), and can not produce dazzling because of light penetrates directly, when increasing gradual change formula atmosphere effect, promote user's use and experience.
Further, the light reflecting portion 40 is inclined with respect to the lower side plate 14. The included angle between the light reflecting part 40 and the lower side plate 14 is 30-60 degrees.
In one example, the light reflecting portion 40 is a separate light reflecting plate, and the light reflecting plate is inclined relative to the lower side plate 14, so that the light reflecting plate forms a certain included angle with the direct light emitted from the light emitting hole 13, and the light seen by human eyes is the light effect of diffuse reflection from the inclined surface of the inclined light reflecting plate, which can weaken the stimulation discomfort feeling to human eyes more than the effect of direct emission through the light guide plate.
In one example, the light reflecting portion 40 is a light reflecting surface formed on the upper surface of the lower end portion of the rear housing 12, and the light reflecting surface is an inclined surface, and similarly, the light reflecting surface forms a certain angle with the direct light emitted from the light emitting hole 13, and the light seen by the human eye is a light effect diffused and reflected by the inclined light reflecting surface, so that the stimulation discomfort feeling to the human eye can be more weakened than the effect directly emitted by the light guide plate.
