[0028] The utility model provides a luminous target board for mounting a prism.

[0029] In the embodiment of this utility model, please refer to Figure 1 and Figure 3 The luminous target board includes:

[0030] A light guide plate 100, comprising a light incident surface 110 and a light emitting surface 120 disposed adjacent to each other. The light guide plate 100 has a mounting opening 130 on the light emitting surface 120. The mounting opening 130 extends through an edge of the light guide plate 100 and is used for mounting a prism (not shown); and

[0031] The light emitting body 200 is disposed on the light guide plate 100 , and emits light toward the light incident surface 110 .

[0032] The technical solution of the present invention configures the mounting plate for mounting the prism as a light guide plate 100. When the visibility in the current measurement environment is low, the light source 200 is controlled to emit light, and the light enters the light guide plate 100 from the light incident surface 110 and is then emitted from the light exit surface 120 of the light guide plate 100, thereby lighting up the light guide plate 100. In this way, the surveyor can quickly find the position of the target card and quickly align the prism to improve measurement efficiency.

[0033] Among them, such as Figure 1 and Figure 2 As shown, the light incident surface 110 can be configured as a side surface of the light guide plate 100, that is, a surface of the light guide plate 100 extending in the thickness direction thereof, or a groove is provided on the surface enclosed by the length and width of the light guide plate 100, and the light incident surface 110 is configured as the side wall of the groove. In this way, the light emitted by the light emitting body 200 can illuminate the surface of the light guide plate 100 enclosed by the length and width, that is, the light emitting surface 120, thereby facilitating observation by the surveyor. It can be understood that the light emitting surface 120 is configured as the surface enclosed by the length and width of the light guide plate 100. The light emitting surface 120 can be a single surface or can be set as two opposite surfaces. In this embodiment, the light emitting surface 120 is set as a single surface, and the other surface opposite to the light emitting surface 120 is provided with a light blocking layer, so that the light entering the light guide plate 100 from the light incident surface 110 can only be emitted from the light emitting surface 120 and the surface of the light guide plate 100 in the thickness direction thereof.

[0034] In one embodiment, please refer to Figure 1 and Figure 3 The light incident surface 110 is configured as a side surface of the light guide plate 100, and the light emitter 200 is strip-shaped and extends along the light incident surface 110. It can be understood that after the light emitted by the light emitter 200 enters the light guide from the light incident surface 110, i.e., the side surface of the light guide plate 100, the light emitter 200 is strip-shaped and can cover the length of the light incident surface 110, so that the largest surface of the light guide, i.e., the light emitting surface 120, can be fully illuminated, and the light emitter 200 will not block the light emitting surface 120, thereby ensuring that the light emitting area of ​​the light guide plate 100 is maximized, so that the surveyor can quickly aim the prism.

[0035] Further, in this embodiment, please refer to Figure 1 and Figure 2The light-emitting body 200 includes a light source 210 and a light guide cover 220. The light guide plate 100 is clamped at the opening of the light guide cover 220. The light source 210 is arranged in the light guide cover 220 and is opposite to the light incident surface 110. It should be noted that the opening of the light guide cover 220 is closed by the light guide plate 100 so that the light emitted by the light source 210 can only be scattered from the light incident surface 110. That is, most of the light emitted by the light source 210 enters the light guide plate 100. While improving the brightness of the light guide plate 100, it also prevents the light from the light source 210 from overflowing and interfering with the surveyor's aiming, thereby facilitating the surveyor to quickly aim the prism. Without loss of generality, the light guide cover 220 also clamps the light source 210 to the edge of the light guide plate 100 where the light incident surface 110 is set, thereby ensuring the installation stability of the light source 210. Of course, in other embodiments, the light source 210 may be arranged only on the light incident surface 110. On the premise that the light emitted by the light source 210 can enter the light guide plate 100, the light emitted by the light source 210 can overflow into the surrounding environment, or the light source 210 can be embedded in the side edge of the light guide plate 100.

[0036] Specifically, in this embodiment, please refer to Figure 2 , the light source 210 is configured as an LED light strip. It should be noted that the LED light strip has the characteristics of small size, good flexibility and easy installation. When installed on the edge surface of the light guide plate 100, it can adapt to various shapes, that is, when the light guide plate 100 is configured as a prism, rectangle or circle, the LED light strip can fit well on the light incident surface 110. At the same time, the LED light strip has high brightness, is energy-saving and environmentally friendly, and is efficient and stable, which increases the use time of the luminous target sign in low visibility conditions. In addition, the LED light strip can emit light of different colors to emit the most obvious light according to different environments, thereby facilitating the surveyor to quickly align the prism. Of course, in other embodiments, the light source 210 can also be configured as an incandescent lamp, a fluorescent lamp, etc.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 The light guide plate 100 includes a mounting edge 140 opposite the light incident surface 110, and the mounting opening 130 is provided through the mounting edge 140. It will be appreciated that, with respect to the light emitting surface 120, the portion from the surface opposite the mounting edge 140 to the mounting opening 130 occupies a larger proportion of the light emitting surface 120. The light incident surface 110 is provided on the side opposite the mounting edge 140 so that the light emitted by the light emitting body 200 can illuminate the entire exterior of the light guide plate 100 and illuminate a majority of the light guide plate 100, thereby facilitating surveyors' quick locating and aiming at the prism at the mounting opening 130. Of course, in other embodiments, the light incident surface 110 can also be provided on a side surface adjacent to the mounting edge 140, or the light incident surface 110 can be provided continuously along the periphery of the light emitting surface 120.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 The luminous target also includes an indicator layer 150, which is disposed on the light-emitting surface 120 and is used to indicate the position of the mounting opening 130. Without loss of generality, the indicator layer 150 can indicate a direction. In this embodiment, the indicator layer 150 points toward the mounting opening 130. Moreover, the color of the indicator layer 150 is inconsistent with the color of the light guide plate 100 and the color of the light emitted by the light source 200. In this way, when the light source 200 emits light to illuminate the light guide plate 100, the indicator layer 150 can indicate the position of the prism on the light-emitting surface 120, guiding the surveyor to quickly aim at the prism. Specifically, the indicator layer 150 is triangular in shape, with its corners opposite to the edge of the mounting port 130 and located in the middle of the edge corresponding to the mounting port 130. In addition, the indicator layer 150 has a certain degree of light transmittance, so that when the light guide plate 100 is lit, the light-emitting surface 120 can display two colors of the indicator layer 150 and the part outside the indicator layer 150, thereby improving the recognition of the light-emitting target and ensuring that the surveyor can quickly align the prism. It should be noted that the indicator layer 150 can be a layer, sticker or raised structure provided on the light-emitting surface 120 of the light guide plate 100. Of course, in other embodiments, indicator blocks of different colors can also be provided in the light guide plate 100, so that different positions of the light guide plate 100 display different colors and indicate the position of the mounting port 130.

[0039] In one embodiment, please refer to Figure 1 and Figure 2 In the direction where the mounting opening 130 passes through the edge of the light guide plate 100, the depth of the mounting opening 130 is greater than half the width of the light guide plate 100. In this way, after the prism is installed in the mounting opening 130, the position of the prism is close to or at the center of the light guide plate 100. That is, the light guide plate 100 forms a semi-enclosed shape around the prism, which can illuminate the prism in the circumferential direction of the prism and highlight the position of the prism. The brightness of the light around the prism tends to be uniform, avoiding interference with observation, so that the surveyor can quickly aim at the prism. Of course, in other embodiments, the depth of the mounting opening 130 can also be less than half the width of the light guide plate 100 to concentrate the brightness of the light guide plate 100 and facilitate finding the position of the light guide plate 100.

[0040] In one embodiment, please refer to Figure 1 and Figure 2The mounting opening 130 includes a mounting portion 131 and an escape portion 132. The mounting portion 131 is wider than the escape portion 132, and the mounting portion 131 is positioned closer to the edge of the light guide plate 100 than the escape portion 132. The prism includes a lens barrel (not shown) and a base (not shown). The lens barrel is positioned corresponding to the escape portion 132, and the base is positioned corresponding to the mounting portion 131. The lens barrel can rotate relative to the base. Specifically, the lens barrel can rotate horizontally and vertically relative to the base, improving the flexibility of the lens barrel adjustment to adapt to various measurement environments. Thus, by setting the width of the mounting portion 131 to be greater than the width of the avoidance portion 132, the cooperation between the mounting portion 131 and the base provides a positioning function for the installation of the prism, improving installation convenience. After the base is installed on the mounting portion 131, the base provides support for the light guide plate 100, ensuring the installation stability of the light guide plate 100. It also prevents the light guide plate 100 from interfering with the rotation of the lens barrel, thereby allowing the lens barrel to be adjusted according to the measured terrain, making it easier for the surveyor to align the lens barrel. In addition, the avoidance portion 132 is located in the middle of the light guide plate 100, so that the lens barrel is located in the middle of the light guide plate 100, making it easier for the surveyor to find the lens barrel. Of course, in other embodiments, the width of the mounting opening 130 can be maintained uniform at all locations along its depth direction, and the base can abut against the side wall of the mounting opening 130 opposite its open end.

[0041] Please note that, please refer to Figure 1 , define the distance between the opening of the mounting opening 130 at the edge of the guide plate and the side wall of the mounting opening 130 relative to the opening as the depth D of the mounting opening 130, and define the distance between the two side walls of the mounting opening 130 adjacent to the opening as the width K of the mounting opening 130, wherein the direction of the width K referred to in this embodiment intersects with the direction of the depth of the mounting opening 130.

[0042] In another embodiment, the light-emitting surface 120 is recessed with a mounting groove, and the light-entering surface 110 is configured as a sidewall of the mounting groove. The light-emitting element 200 is mounted in the mounting groove. It will be appreciated that the distance between the light emitted by the light-emitting element 200 in the mounting groove and each edge of the guide plate is equal or nearly equal. This ensures uniform brightness across the light guide plate 100, making it easier for surveyors to accurately locate the illuminated target. Furthermore, the mounting groove protects the light-emitting element 200, preventing damage.

[0043] In one embodiment, please refer to Figure 1 and Figure 2The light-emitting body 200 is connected to the power supply assembly through the conductive wire 300. The conductive wire 300 is provided with a switch 400, and the switch 400 is used to control the operation of the light-emitting body 200. It should be noted that the switch can adjust the brightness of the light-emitting body 200 and the color emitted by the light-emitting body 200 while controlling the lighting and extinguishing of the light-emitting body 200. For example, the switch 400 adjusts the brightness of the light-emitting body 200 to adapt to the visibility of the current environment, so as to avoid the brightness being too low and unable to quickly find the prism, and to avoid the brightness being too high and interfering with the observation and search for the prism; and the switch adjusts the color of the light-emitting body 200 to improve the recognition of the light-emitting body 200 in the current environment, thereby facilitating the surveyor to quickly find the prism and improve the measurement efficiency. Specifically, the conductive wire 300 can be fixed by a connector connected to the light guide plate 100 to prevent the conductive wire 300 and the switch 400 from interfering with the stability of the light-emitting target, thereby facilitating the measurement operation. Of course, in other embodiments, the target sign may also be provided with an independent power supply, which is arranged on the side of the light guide plate 100 away from the light emitting surface 120 and is electrically connected to the light-emitting body 200 through the conductive wire 300, so that the light-emitting target sign can adapt to various environments while avoiding blocking the light emitting surface 120.

[0044] The present invention also proposes a prism assembly, which includes a prism and a luminous target. The specific structure of the luminous target refers to the above-mentioned embodiment. Since the present prism assembly adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0045] Among them, the prism is installed at the mounting port, and the light guide plate is configured as a semi-enclosed structure for the prism. When the visibility in the current measurement environment is low, the light source emits light, and the light enters the light guide plate from the light incident surface and then exits from the light exit surface of the light guide plate, thereby lighting up the light guide plate. This makes it easier for measurement personnel to quickly find the position of the target card based on the lit light guide plate, thereby quickly aiming at the prism and improving measurement efficiency.

[0046] Furthermore, in this embodiment, the prism includes a lens barrel and a base. The lens barrel is located in the middle of the light guide plate and spaced apart from the sidewalls of the mounting opening. The base abuts the sidewalls of the mounting opening, and the lens barrel can rotate relative to the base, including horizontal and vertical rotation. In this way, the base provides support for the light guide plate, ensuring the installation stability of the light guide plate while also preventing the light guide plate from interfering with the rotation of the lens barrel. This allows the lens barrel to be adjusted according to the measured terrain, making it easier for surveyors to align the lens barrel in the prism and improving measurement efficiency.

[0047] The above description is merely an optional embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
