Description

Technical Field

[0001] The present invention relates to the field of mobile phone cameras, and in particular to a light-averaging structure for cameras. Background Art

[0002] Mobile phone cameras feature indicator lights to indicate power on, power off, and other status signals. Current indicator lights primarily consist of a housing, a light bead, and a light guide. The light bead is located within the housing and emits light, while the light guide directs the light generated by the light bead outside the housing. Currently, common light guides are cylindrical or bar-shaped. Cylindrical light guides only display color at their ends, while bar-shaped light guides only display color on one side. These indicators are difficult to meet the multi-faceted color requirements of some current mobile phone cameras, such as those in L-shaped configurations.

[0003] Currently, when multi-sided color display is required, multiple LEDs are typically used, and these LEDs are formed into a light strip to illuminate multiple sides of the indicator light. However, the energy consumption of multiple LEDs increases with the number of LEDs, resulting in high power consumption for the camera. Furthermore, more complex electronic components are required to support the operation of multiple LEDs, increasing the cost of the camera. Furthermore, when multiple LEDs are placed too close to the display housing, the light intensity varies from area to area, resulting in uneven color display and a poor user experience. Summary of the Invention

[0004] The present invention aims to provide a light-uniform structure for a camera, which can display colors on at least two sides without using multiple lamp beads, thereby reducing energy consumption and making the light more uniform.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a light-equalizing structure for a camera, comprising a shell, a lighting assembly, and a light guide unit, wherein the lighting assembly and the light guide unit are both located in the shell, and are characterized in that the light guide unit comprises a first light guide column, a second light guide column, and a third light guide column, wherein the angle between the first light guide column and the second light guide column is greater than 0° and less than or equal to 90°, the third light guide column is located between the first light guide column and the second light guide column, and the angle between the third light guide column and the first light guide column and the angle between the third light guide column and the second light guide column are both acute angles, and the first light guide column and the second light guide column are both fixed to the third light guide column; an opening is provided on the shell facing the first light guide column and the second light guide column, and the first light guide column and the second light guide column are embedded in the opening toward the side wall of the shell; the lighting assembly comprises a first lamp bead, and the end of the third light guide column away from the first light guide column is opposite to the first lamp bead.

[0006] The beneficial effects of this program are:

[0007] 1. The third light guide column in this solution is opposite to the first lamp bead. Part of the light generated by the first lamp bead is transmitted along the third light guide column to the first light guide column and the second light guide column, and then refracted from the first light guide column and the second light guide column; another part of the light is transmitted along the air into the first light guide column and the second light guide column, and then refracted through the first light guide column and the second light guide column. This part of the light is mainly refracted from the parts of the first light guide column and the second light guide column away from the third light guide column, and cooperates with the light transmitted through the third light guide column to make the light refracted from both ends of the first light guide column and the second light guide column more uniform.

[0008] 2. Because the first lamp bead is far away from the first light guide column and the second light guide column, the first lamp bead will not form a bright area on the outside of the housing that is significantly brighter than other parts, further making the brightness of the indicator light more uniform.

[0009] Furthermore, the connection position between the first light guide column and the second light guide column and the third light guide column is an end where the first light guide column and the second light guide column are close to each other.

[0010] The beneficial effect of this solution is that light that does not pass through the third light guide is primarily refracted from the first and second light guides, away from the third light guide. In this solution, the light that passes through the third light guide and enters the first and second light guides gradually weakens along the first and second light guides from the end closest to the third light guide to the end away from the third light guide. The combination of these two portions of light further makes the light refracted from both ends of the first and second light guides more uniform.

[0011] Furthermore, a plurality of protrusions are fixed on the side of the third light guide column facing the first light guide column, and the plurality of protrusions are distributed in sequence along the length direction of the third light guide column.

[0012] The beneficial effects of this solution are as follows: the protrusions create a curved surface on the third light guide. Light reflected along the third light guide has different incident angles at different locations on the curved surface, resulting in different refraction angles for light at different locations. This further disperses the light, allowing it to enter the first and second light guides more evenly. Furthermore, some light from the curved surface is refracted from the surface, passes through the air, and then refracts from the first light guide near the protrusions, further distributing the light.

[0013] Furthermore, the cross section of the protrusion is triangular, and the tip of the triangle away from the third light guide pillar is directed toward the first light guide pillar.

[0014] The beneficial effect of this solution is that the triangular protrusion not only reflects part of the light transmitted along the third light guide column, but also allows the light to be refracted from the side wall of the protrusion and transmitted to the first light guide column through the air, thereby better dispersing the light.

[0015] Furthermore, the end of the third light guide column away from the first light guide column is inclined toward the side close to the second light guide column, and the vertical distance between the end of the third light guide column away from the first light guide column and the second light guide column is smaller than the vertical distance between the end of the third light guide column and the first light guide column; the lighting assembly also includes a second lamp bead, which is higher than the first lamp bead and opposite to the first light guide column.

[0016] The beneficial effect of this solution is that the light in this solution can be better transmitted in the third light guide column. Secondly, in addition to being transmitted along the end of the third light guide column close to the second light guide column, the light generated by the first lamp bead can be mainly refracted from the end of the third light guide column away from the second light guide column and directly transmitted into the second light guide column. It is refracted by the second light guide column and supplements the light refracted from the end of the second light guide column away from the first light guide column. The light generated by the second lamp bead is mainly transmitted into the first light guide column through the air, supplementing the light at the part of the first light guide column that is not connected to the third light guide column, further making the light refracted from various parts of the first and second light guide columns more uniform.

[0017] Furthermore, a fixing plate is fixed in the housing, and the first lamp bead and the second lamp bead are respectively located at the bottom and top of the fixing plate.

[0018] The beneficial effects of this solution are: the fixing plate facilitates the installation of the first lamp bead and the second lamp bead, and secondly, the fixing plate can also block the light generated by the second lamp bead from being transmitted to the side close to the second light guide column, thereby avoiding excessive light refracted through the part of the second light guide column that is not connected to the third light guide column, causing the second light guide column to be too bright, and further promoting a more uniform brightness of various parts of the indicator light.

[0019] Furthermore, the fixing plate is a circuit board.

[0020] The beneficial effect of this solution is that it does not require the provision of an additional plate, making installation more convenient.

[0021] Furthermore, the top of the third light guide column away from one end of the first light guide column is a plane, and the plane is perpendicular to the first lamp bead.

[0022] The beneficial effect of this solution is that the plane can better allow light to enter the third light guide column and prevent excessive light from being reflected by the surface of the third light guide column into the first light guide column, making the brightness of the first light guide column and the second light guide column more uniform.

[0023] Furthermore, the bottom of the third light guide column away from the end of the first light guide column is an arc-shaped surface, and the arc-shaped surface is located directly below the plane.

[0024] The beneficial effect of this solution is that the arc surface can better reflect the light entering the third light guide column through the plane, so that the light is transmitted along the third light guide column.

[0025] Furthermore, two reinforcement blocks are fixed to the inner wall of the shell, and the two reinforcement blocks are respectively located on both sides of the first light guide column. The reinforcement block includes a first reinforcement part and a second reinforcement part that are fixedly connected. The first reinforcement part is located between the second reinforcement part and the light guide column, and the thickness of the first reinforcement part is less than the thickness of the second reinforcement part.

[0026] The beneficial effect of this solution is that the two reinforcing blocks can limit the first light guide column and enhance the strength of the housing to prevent the housing from being damaged by pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] A camera with a uniform light structure, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a shell 4, a lighting component, and a light guide unit. The lighting component and the light guide unit are all located in the shell 4. The light guide unit includes a first light guide column 1, a second light guide column 2, and a third light guide column 3. The first light guide column 1, the second light guide column 2, and the third light guide column 3 are integrally injection molded using PC material, wherein the first light guide column 1 and the second light guide column 2 are perpendicular, the left wall of the shell 4 is arc-shaped, and the left wall and bottom of the shell 4 are both provided with openings, the left wall of the first light guide column 1 is embedded in the opening of the left wall of the shell 4, and the bottom of the second light guide column 2 is embedded in the opening at the bottom of the shell 4.

[0036] The connection position between the left end of the third light guide column 3 and the first light guide column 1 and the second light guide column 2 is located at the intersection of the first light guide column 1 and the second light guide column 2. The angle between the center line of the left end of the third light guide column 3 and the second light guide column 2 is 35° to 47°. Specifically, the angle between the center line of the left end of the third light guide column 3 and the second light guide column 2 in this embodiment is 41°. The right end of the third light guide column 3 is inclined toward the side close to the second light guide column 2, that is, the angle between the center line of the right end of the third light guide column 3 and the second light guide column 2 is smaller than the angle between the center line of the left end of the third light guide column 3 and the second light guide column 2. In this embodiment, the top of the right end of the third light guide column 3 is a plane 32, and the bottom of the right end is an arcuate surface, and the arcuate surface is directly opposite the plane 32. A fixing plate 5 is screwed into the housing 4. In this embodiment, the fixing plate 5 is a PCB. It is horizontally arranged, with its left end positioned directly above the plane 32. A first lamp bead 51 is mounted on the bottom of the fixing plate 5, and a second lamp bead 52 is mounted on the top. In this embodiment, both the first and second lamp beads 51, 52 are LEDs. The first lamp bead 51 faces downward and directly faces the plane 32, while the second lamp bead 52 faces upward and faces the middle and upper portions of the first light guide 1.

[0037] The top of the left end of the third light guide column 3 is integrally injection-molded with several protrusions 31, which are prisms, and are distributed in sequence along the length direction of the third light guide column 3. Specifically, the protrusion 31 in this embodiment is a triangular prism, that is, the cross-section of the protrusion 31 is a triangle, and the protrusion 31 is away from the top angle of the third light guide column 3 toward the first light guide column 1, and the top of the left end of the third light guide column 3 is serrated.

[0038] Combine Figure 4 As shown, two reinforcement blocks 6 are integrally injection-molded within the housing 4. Both reinforcement blocks 6 are vertically arranged and located on either side of the first light guide column 1. The reinforcement blocks 6 in this embodiment include an integrally injection-molded first reinforcement portion 61 and a second reinforcement portion 62. The first reinforcement portion 61 is located between the second reinforcement portion 62 and the first light guide column 1. The thickness of the first reinforcement portion 61 is less than that of the second reinforcement portion 62. The side wall of the second reinforcement portion 62 away from the first reinforcement portion 61 smoothly transitions to the inner wall of the housing 4. In this embodiment, the left wall of the housing 4 is arc-shaped, and the front and rear side walls are horizontal planes 32. The second reinforcement portion 62 is in contact with the end of the arc portion close to the horizontal plane 32 to prevent deformation of the arc portion when the housing 4 is squeezed.

[0039] Combine Figure 2 、 Figure 3 and Figure 5 The specific implementation process is as follows:

[0040] When the first lamp bead 51 and the second lamp bead 52 are working, the light of the first lamp bead 51 enters the third light guide column 3 through the plane 32 at the right end of the third light guide column 3, and part of the light is transmitted to the left along the third light guide column 3. When the light is transmitted to the protrusion 31, part of the light is refracted through the side wall of the protrusion 31. Because the inclination direction of the side wall of each protrusion 31 is different, the angle between the light refracted from each side wall and the vertical plane is different. Therefore, the contact position of the light with the first light guide column 1 is different, and it can be refracted from different positions of the first light guide column 1. Secondly, another part of the light is reflected by the side wall of the protrusion 31. Similarly, the angle of the light after being reflected by different side walls is also different. Therefore, the light can be further dispersed by the protrusion 31, so that the light is transmitted to the first light guide column 1 and the second light guide column 2 at different angles and positions.

[0041] Secondly, another part of the light entering the third light guide column 3 is refracted through the right end of the third light guide column 3 and finally transmitted to the end of the second light guide column 2 away from the first light guide column 1. On the basis of the light transmitted from the third light guide column 3 to the second light guide column 2, the light refracted from the second light guide column 2 is supplemented, so that the light refracted from various parts of the second light guide column 2 is uniform.

[0042] The light from the second lamp bead 52 is mainly transmitted to the middle and upper parts of the first light guide column 1 through the air. On the basis of the light transmitted from the third light guide column 3 to the first light guide column 1, the light refracted from the first light guide column 1 is supplemented, so that the light refracted from various parts of the first light guide column 1 is more uniform.

[0043] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
