Detailed Implementation
[0037] The technical solution of this utility model will be further described below with reference to specific embodiments.
[0038] like Figures 1 to 5 As shown, this utility model provides a beam-splitting structure for a sign light, comprising: a light guide 1, including a first sign 2 and a second sign 3, wherein the first sign 2 is disposed above or below the second sign 3; and a light source plate 4 disposed on the side of the light guide 1, wherein the light source plate 4 is provided with a first light source 41 and a second light source 42, wherein the light from the first light source 41 illuminates the first sign 2 and the light from the second light source 42 illuminates the second sign 3; in an emergency, the light source plate 4 can control the light from the first light source 41 and / or the light from the second light source 42 to illuminate the first sign 2 and the second sign 3 respectively according to usage requirements, thereby achieving selective control. The purpose of illuminating the first marker 2 and the second marker 3 is as follows: Since the first marker 2 is positioned above or below the second marker 3, the light from the light source on the light source plate 4 can be directed from one side of the light guide 1 to the light guide 1. The length of the light source plate 4 can be designed according to the height of the light guide 1, thus shortening the length of the light source plate 4 and effectively saving product costs. A light-blocking part 5 is provided between the first marker 2 and the second marker 3. The light-blocking part 5 can block light and prevent light from passing through the first marker 2 to the second marker 3, or light from the second marker 3 to the first marker 2, so that the user can clearly understand the indicator information of the lamp when observing the light guide 1.
[0039] The light guide 1 has a long light-inlet section 31 and a short light-inlet section 21 on its side, corresponding to the position of the light source plate 4. The short light-inlet section 21 is disposed on the first marker 2, and the long light-inlet section 31 is disposed on the second marker 3. The first marker 2 has a first display section 22, and the second marker 3 has a second display section 32. The height of the short light-inlet section 21 is less than the height of the first display section 22, and the height of the short light-inlet section 21 is greater than one-quarter of the height of the long light-inlet section 31. The first display section 22 and the second display section 32 are provided with a logo graphic 11 for the overall aesthetics of the lamp. For aesthetic appeal and ease of user observation, the logo graphic 11 is mostly positioned on the horizontal center line of the light guide 1. The light guide 1 has a long light-entry section 31 and a short light-entry section 21, which can prevent the light-blocking section 5 between the first logo 2 and the second logo 3 from penetrating the logo graphic 11 and damaging its integrity. The light from the first light source 41 enters the first display section 22 through the short light-entry section 21, thus illuminating the first display section 22. The light from the second light source 42 enters the second display section 32 through the long light-entry section 31, thus illuminating the second display section 32.
[0040] The second display section 32 is disposed above or below the short light-inlet section 21. The side of the short light-inlet section 21 and the side of the first display section 22 are transitioned by an arc surface and / or a slope. The length of the short light-inlet section 21 is parallel to the horizontal plane. This structure can guide the light from the first light source 41 to fully enter the first display section 22 through the short light-inlet section 21, avoid light waste, and make the light in the first display section 22 more uniform.
[0041] The size and shape of the first marker 2 are consistent with the size and shape of the second marker 3. This structure enables the first marker 2 and the second marker 3 to be interchangeable. Manufacturers can use the first marker 2 as the second marker 3 simply by rotating it, which effectively reduces the inventory of product accessories and saves product costs.
[0042] Both the first marker 2 and the second marker 3 are provided with marker graphics 11. The two marker graphics 11 are oriented in opposite directions and are separated from each other by the light-blocking part 5. The first marker 2 and the second marker 3 are independent of each other. It should be noted that the first marker 2 and the second marker 3 are functionally independent, that is, they emit light from each other without affecting each other. For ease of production, the first marker 2 and the second marker 3 can be simply connected before the light-blocking part 5 is assembled / produced. This structure should also be included in the protection scope of this utility model.
[0043] The light guide 1 is made of glass or light-guiding plastic. The light-blocking part 5 includes a connecting surface between the first marker 2 and the second marker 3 and a reflective adhesive on the connecting surface. The first marker 2 and the second marker 3 are connected as one unit by the adhesive. This structure makes the first marker 2 and the second marker 3 integrated, making the light guide 1 more robust overall. It is also more convenient for manufacturers to assemble, and it can better reflect the light that escapes from the first marker 2 back to the first marker 2, or the light that escapes from the second marker 3 back to the second marker 3. This allows users to clearly understand the indicator information of the lamp when observing the light guide 1.
[0044] In some embodiments, the light guide 1 is made of light-guiding plastic, and the light-blocking part 5 includes a connecting surface between the first marker 2 and the second marker 3 and a reflective element made of plastic disposed on the connecting surface. The first marker 2 and the second marker 3 are integrally formed with the reflective element by two-color injection molding. This structure makes the first marker 2 and the second marker 3 integrally connected, and the light guide 1 is more robust as a whole. It is more convenient for manufacturers to assemble, and it can better reflect the light lost from the first marker 2 back to the first marker 2, or the light lost from the second marker 3 back to the second marker 3, so that users can clearly understand the indicator information of the lamp when observing the light guide 1.
[0045] In some embodiments, the light guide 1 is made of glass or a light-guiding plastic, and the light-blocking part 5 includes a connecting surface between the first marker 2 and the second marker 3 and a reflective element disposed on the connecting surface. The reflective element can be attached to and detached from the connecting surface. This structure allows light leaking out of the first marker 2 to be reflected back to the first marker 2, or light leaking out of the second marker 3 to be reflected back to the second marker 3, so that the user can clearly understand the indicator information of the lamp when observing the light guide 1.
[0046] The second light source 42 is positioned on the light source plate 4 to match the upper position of the long light-inlet section 31. The center of the second light source 42 is on the same horizontal line as the horizontal center line of the light guide 1; there is one second light source 42; or there are two or more second light sources 42, with the center point between the two furthest second light sources 42 on the same horizontal line as the horizontal center line of the light guide 1; the light source plate 4 includes a battery 43, which is positioned on the side of the long light-inlet section 31 and is located away from the horizontal center line of the light guide 1. For the overall aesthetics of the lamp and to facilitate user observation of the marking graphic 11, the marking graphic 11 is mostly set on the horizontal center line of the light guide 1. This structure ensures that the light is uniform and aesthetically pleasing after the marking graphic 11 is set on the horizontal center line of the light guide 1.
[0047] The number of the first light source 41 and the number of the second light source 42 are both two or more. The spacing between the first light source 41 is smaller than the spacing between the second light source 42. This structure can ensure that even if the height of the short light-inlet section 21 is smaller than the height of the long light-inlet section 31, the light displayed by the first display section 22 and the second display section 32 is consistent.
[0048] The first marker 2 is provided with an assembly hole 12, which is located inside the short light-entry section 21. The first light source 41 is located between the assembly hole 12 and the light-blocking section 5. This structure prevents light from being refracted due to the obstruction of the assembly hole 12, thus avoiding damage to the light transmission.
[0049] The light guide 1 has housings 6 on both sides, and the light source plate 4 is disposed in one of the housings 6. The housing 6 includes a front housing and a rear cover, and the rear cover covers the front housing. The housing 6 can protect the light source plate 4 and ensure the service life of the lamp.
[0050] Since the light-blocking part 5 can be clearly displayed when the first sign 2 or the second sign 3 is lit, users may find it unsightly to display the light-blocking part 5 in some places. Therefore, the surface of the light guide 1 is provided with a sign plate 7, and the sign plate 7 is provided with a sign hole 71. Both the first sign 2 and the second sign 3 are provided with a sign graphic 11. The shape and position of the sign hole 71 are adapted to the shape and position of the sign graphic 11. The light-blocking part 5 is blocked from being displayed to the outside by the sign plate 7.
[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
