As shown in fig. 1, an embodiment of the present invention provides a shift luminescent panel, including: a shift panel 10, a light guide panel 20 and a single light emitting source 30.
The shift panel 10 is provided with a plurality of shift symbol portions 11, and the plurality of shift symbol portions 11 are provided at intervals. Here, each of the shift symbol portions 11 has a different meaning, and for example, as shown in fig. 4, the shift symbol portion 11"p" represents a parking range, the shift symbol portion 11"r" represents a reverse range, the shift symbol portion 11"n" represents a neutral range, the shift symbol portion 11"d" represents a forward range, and the like. In fig. 4, 4 shift symbol portions 11 are shown for illustrative purposes, but it is obvious to those skilled in the art after reading the following technical solutions that the solution is applied to the technical solutions of less than four or more than four shift symbol portions 11, which also falls within the protection scope of the present invention. It can be understood that the specific number of the shift symbol portions 11 and the arrangement manner on the shift panel 10 can be specifically set according to actual requirements to better meet the actual requirements.
The single light emitting source 30 is disposed below the light guide panel 20, light emitted by the single light emitting source 30 enters the light guide panel 20 through the incident surface 21 and then irradiates the first reflecting surface 22, the light irradiates the second reflecting surface 23 after being reflected by the first reflecting surface 22, and the light leaves the light guide panel 20 from the exit surface 24 after being reflected by the second reflecting surface 23 and finally irradiates the shift symbol portion 11 of the shift panel 10. The single light emitting source 30 is fixed to the PCB board 40.
The light guide panel 20 is a core element of the shift light emission panel. The incident surface 21 of the light guide panel 20 is a hemisphere, and the single light emitting source 30 is located at the center of the hemisphere. The first reflective surface 22 is a parabolic surface formed by rotating a parabolic section, and the parabolic section satisfies the following equation:
the center of the hemisphere is the origin of coordinates, the direction perpendicular to the horizontal plane is the positive direction of the y axis, any straight line passing through the origin and perpendicular to the y axis is the x axis, and A is the distance from the vertex of the parabola to the focus of the parabola. The first reflecting surface 22 is a parabolic surface formed by rotating a parabolic section by one rotation with the y-axis as a rotation axis.
The second reflecting surfaces 23 of the light guide panel 20 are located at two ends of the light guide panel 20, and the second reflecting surfaces are inclined planes and form an included angle of 45-60 degrees with the horizontal plane. The inclined surfaces are provided in plural, and correspond to the shift symbol portions 11 one to one. The second reflecting surface 23 is provided with a step embossing at a position corresponding to the plurality of shift symbol portions 11. The light guide panel 20 has a frosted area 241 provided on the emission surface 24 at a position corresponding to the plurality of shift symbol portions.
The plurality of shift symbol portions 11 of the shift panel 10 are translucent, and the rest of the shift panel 10 is opaque.
Preferably, the single light emitting source 30 is an LED light emitting source, and the single light emitting source 30 is mounted on the PCB 40. The light guide panel 20 is made of optical plastic structural adhesive, and may be made of optical PMMA plastic or PC plastic.
The working principle of the inventive shifting panel according to the invention will be explained in the following with reference to the specific embodiments in conjunction with the actual situation.
The single light emitting source 30 adopts a single LED lamp, the LED lamp is directly attached to the PCB 40, the LED lamp can be selected from common LEDs on the market, the size and the light emitting angle are not limited, the material selectivity is wide, and the universality is high. The radius r of the incident surface 21 of the light guide panel 20 needs to be defined according to the size, the light emitting angle and the like of the LED lamp, if r is too small, the incident surface 21 cannot fully surround the light emitting angle of the single light emitting source 30, and the utilization rate of edge light is reduced; if r is too large, the hemispherical volume of the incident surface 21 becomes large, which increases the thickness of the bottom of the entire light guide panel 20, and thus increases the volume of the entire product, which increases the cost and the difficulty of the manufacturing process. For example, if 3825 packages are selected for the LED (the size is 3.8mm long × 2.5mm wide, and the light emitting angle is 120 °), r is defined as 3.8mm, which can satisfy the overall coverage of the light emitting angle and maximize the light efficiency; if the selected LED size is smaller or the light emission angle is smaller, a smaller r can be defined.
The focal coordinate of the parabola is the origin (0,0), the vertex of the parabola is (-A, 0), and the parabola surface is formed by rotating a parabola section segment around the y axis, as shown in fig. 1, the section of the parabola section segment is parabolic symmetry, the distance between two vertexes is 2A, the value of 2A is slightly larger than r, and the value of A can be 2mm if the value of r is 3.8 mm.
Therefore, the parameters of the incident surface 21 and the first reflecting surface 22 are determined according to the size of the LED and the light emitting angle thereof, and the present invention does not provide any limitation on the selection of the LED, but only explains the operation principle thereof and the determination manner of the parameters of the light guide panel 20. The foregoing is a more detailed description of the invention, taken in conjunction with specific preferred embodiments thereof, and is not intended to limit the invention thereto.
The incident surface 21 and the first reflecting surface 22 shape the light emitted from the single light-emitting source 30. When the light emitted from the sphere center passes through the hemispherical surface, the light path is unchanged and still propagates along a straight line, and the light emitted from the focus of the parabola is reflected by the parabola and then is emitted in the direction parallel to the x axis. The single light source 30 is located at the hemispherical center point and the focus of the parabola, the light emitted by the single light source 30 still propagates along a straight line after passing through the incident surface 21, is totally internally reflected when reaching the first reflecting surface 22, propagates around along the direction parallel to the light guide panel 20, and irradiates the second reflecting surfaces 23 located at the two ends of the light guide panel 20.
Step embossing is arranged on the second reflecting surface 23 corresponding to the plurality of gear shifting symbol parts 11, step embossing areas correspond to the gear shifting symbol parts 11 one by one, and meanwhile, the included angle between the inclination of the step embossing and the horizontal plane is 45-60 degrees, and the area of the step embossing is composed of a plurality of small steps. When parallel light rays irradiated from the side edge pass through the step embossing, the total internal reflection is carried out, then the emergent surface 24 perpendicular to the light guide panel 20 leaves the light guide panel 20, and then the light rays irradiate the plurality of gear shifting symbol parts 11, so that the light emitting effect is generated, and the purpose of panel light emitting is achieved.
Preferably, a frosted area 241 is disposed on the emitting surface 24 at a position corresponding to the plurality of shift symbol portions 11, and the frosted area 241 diffuses light to make the light uniform, so that the uniformity of the illumination brightness of the plurality of shift symbol portions 11 is better, and the light emitted from the plurality of shift symbol portions 11 is more uniform.
According to the gear shifting light-emitting panel, a single light-emitting source is adopted to irradiate the light guide panel, so that a plurality of gear shifting symbol parts can be illuminated, compared with the traditional mode that a plurality of LED lamps and a plurality of light guide blocks are arranged, the power consumption is low, and the corresponding heat dissipation, circuit and structure and the like are simpler in design, so that the problems of large quantity of LED lamps, large power consumption and complex design of the traditional gear shifting panel are solved.
The invention further provides a vehicle comprising the gear shifting light-emitting panel.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
