[0002] For the aesthetics of medical devices and to enable staff to clearly identify the device model, marker lamps are installed on their outer casings. However, in order to achieve uniform light emission, existing marker lamps are usually installed by laying multiple light strips, resulting in high power consumption and large heat generation. Summary of the Utility Model
[0003] Based on this, in view of the above technical problems, the utility model provides a marker lamp.
[0004] A marker lamp includes: a font board having a display hollow; a rear cover connected to the font board and enclosing a receiving cavity with the font board; a light-emitting board installed in the receiving cavity; and a light-emitting strip connected to an edge in the length direction and / or width direction of the light-emitting board. Wherein, the light-emitting board includes a light homogenizing board and a diffusion board, and the light homogenizing board is connected to a side of the diffusion board close to the font board.
[0005] With such a setting, the receiving cavity formed by the font board and the rear cover can protect the internal components located therein. The light-emitting strip is located at the edge of the light-emitting board, so only one light strip needs to be provided, with lower power consumption. And the light emitted by the light strip will enter the light-emitting board from the edge of the light-emitting board. Since the light homogenizing board is located between the diffusion board and the font board, the light will first pass through the diffusion board. The diffusion board can change the direction and distribution of the light. Then the light passes through the light homogenizing board and propagates into the font board through scattering and refraction in the light homogenizing board, and irradiates outward from the display hollow, forming a uniform light sight effect.
[0006] In one embodiment, the diffusion board is provided with pits, and the openings of the pits face the font board.
[0007] In one embodiment, there are multiple pits, and they are evenly arranged in an array on the diffusion board.
[0008] In one embodiment, the light-emitting board further includes a protection strip. The protection strip includes a bearing section and a supporting section. The bearing section and the supporting section are connected and arranged at an angle. The light-emitting strip is installed on the bearing section. One side in the width direction of the light-emitting board is connected to the light-emitting strip, and the side of the light-emitting board away from the font board abuts against the supporting section.
[0009] In one embodiment, the font plate includes a front baffle and a light-transmitting plate. The front baffle is connected to the light-transmitting plate, and the front baffle is located on the side of the light-transmitting plate facing away from the light-emitting plate. The front baffle is provided with the display cutout.
[0010] In one embodiment, the light transmittance of the light-transmitting plate is 10%-50%.
[0011] In one embodiment, a frame is provided at the edge of the light-transmitting plate. The frame is connected to the rear cover and cooperates to enclose the accommodation cavity.
[0012] In one embodiment, a plurality of heat dissipation holes are provided in the rear cover, and the heat dissipation holes are evenly spaced.
[0013] In one embodiment, a protrusion is provided on the rear cover, and the protrusion abuts against the side of the light-emitting plate facing away from the font plate.
[0014] The present utility model further provides a medical device, including a device main body and the above-mentioned indicator light. The indicator light is installed in the device main body, and the light-emitting plate is electrically connected to the device main body through a shielding joint.
[0015] Compared with the prior art, by providing a diffusion plate and a light homogenizing plate, the light emitted from one light-emitting strip can be evenly scattered after passing through the diffusion plate and the light homogenizing plate, reducing energy consumption and heat generation, while making the light-emitting fonts on the indicator light display more evenly. In addition, a plurality of pits are provided on the diffusion plate to further improve the ability of the diffusion plate to change the light propagation direction, so that the light propagation is more uniform.

[0027] The present utility model provides a marker lamp 100, which is applied to a magnetic resonance system and can meet the requirement of low power consumption on the premise of emitting uniform light.
[0028] Please refer to Figures 1-4 , the marker lamp 100 includes a font plate 10, a rear cover 30, a light-emitting plate 20 and a light-emitting strip 40. The font plate 10 has a display cutout 111. The rear cover 30 is connected to the font plate 10 and encloses a receiving cavity with the font plate 10. The light-emitting plate 20 is installed in the receiving cavity. The light-emitting strip 40 is connected to the edges in the length direction and width direction of the light-emitting plate 20. The light emitted by the light-emitting strip 40 can be transmitted to the display cutout 111 through the light-emitting plate 20. Among them, the light-emitting plate 20 includes a light homogenizing plate 21 and a diffusion plate 22. The light homogenizing plate 21 is connected to the side of the diffusion plate 22 close to the font plate 10. In this way, the receiving cavity formed by the font plate 10 and the rear cover 30 can protect the internal components located therein. The light-emitting strip 40 is located at the edge of the light-emitting plate 20, so only one light-emitting strip 40 needs to be provided, and the power consumption is low. Moreover, the light emitted by the light-emitting strip 40 enters the light-emitting plate 20 from the edge of the light-emitting plate 20. Since the light homogenizing plate 21 is located between the diffusion plate 22 and the font plate 10, the light will first pass through the diffusion plate 22. The diffusion plate 22 can change the direction and distribution of the light. Then the light passes through the light homogenizing plate 21 and propagates into the font plate 10 through scattering and refraction in the light homogenizing plate 21, and irradiates outwards from the display cutout 111, forming a sight effect with uniform light.
[0029] It should be explained that the existing marker lamps usually achieve the illumination effect of uniform light by setting multiple lamp belts, while this application only needs one lamp belt to achieve the light homogenizing effect, and the power consumption is lower than that of the existing marker lamps.
[0030] Further, the diffusion plate 22 is provided with pits (not shown in the figure), and the openings of the pits face the font plate 10. In this way, when the light propagates to the pits on the diffusion plate 22, it will be refracted by the pit walls of the pits, thereby changing the propagation angle, and thus improving the light homogenizing ability of the diffusion plate 22.
[0031] Furthermore, there are multiple pits, and they are evenly arranged in an array on the diffusion plate 22. In this way, the uniformity of the light passing through the diffusion plate 22 is further improved.
[0032] Of course, in other embodiments, if there is a need for some areas to be highlighted and some areas to be dimmed, the pits on the diffuser plate 22 can also be adaptively changed to change the light propagation, so that the visual effect of the marker lamp 100 meets the requirements, not limited to the above-mentioned uniform array layout method.
[0033] The light-emitting plate 20 further includes a protection strip 23. The protection strip 23 includes a bearing section 231 and a support section 232. The bearing section 231 and the support section 232 are connected and arranged at an angle. A light-emitting strip 40 is installed on the bearing section 231. One side in the width direction of the light-emitting plate 20 is connected to the light-emitting strip 40, and the side of the light-emitting plate 20 away from the font plate 10 abuts against the support section 232. In this way, the protection strip 23 is used to provide an installation space for the light-emitting strip 40 and the light-emitting plate 20, making the installation of the two more stable and protecting the light-emitting strip 40 and the light-emitting plate 20.
[0034] In this embodiment, the light-emitting strip 40 is installed at the edge of the diffuser plate 22 so that light first enters the diffuser plate 22. And after the light-emitting plate 20 is installed on the protection strip 23, preferably, a light-shielding tape is used to fit around the light-emitting plate 20 to prevent light leakage.
[0035] Preferably, when the marker lamp 100 is installed in a medical device, since the medical device is placed on a horizontal ground, the side of the medical device that fits the ground is defined as the bottom, and the side of the marker lamp 100 close to the ground is also the bottom. The lamp strip and the protection strip 23 are both arranged at the bottom of the light-emitting plate 20, and light enters the diffuser plate 22 from the bottom up, then enters the light homogenizing plate 21 along the horizontal direction and irradiates towards the display cutout 111.
[0036] The font plate 10 includes a front baffle 11 and a light-transmitting plate 12. The front baffle 11 and the light-transmitting plate 12 are connected, and the front baffle 11 is located on the side of the light-transmitting plate 12 facing away from the light-emitting plate 20. The light-transmitting plate 12 is made of a light-transmitting material, and the front baffle 11 is made of an opaque material and is provided with a display cutout 111. In this way, since the light-transmitting plate 12 is made of a light-transmitting material, light can pass through the light-transmitting plate 12 and pass out from the display cutout 111, while the front baffle 11 is made of an opaque material, so only the light at the display cutout 111 can be smoothly transmitted to the outside, and the rest are blocked by the front baffle 11 to improve the display effect.
[0037] The front baffle 11 is processed and formed by using an epoxy board or an unsaturated resin board, so as to be bonded to the shell of the medical device it is applied to as a whole, prevent shrinkage marks, and improve the visual integration degree with the MRI shell after being polished and painted.
[0038] Preferably, the light transmittance of the light-transmitting plate 12 is 10%-50%, which not only prevents the light from passing through the light-transmitting plate 12 with too low light transmittance, resulting in unclear font display on the indicator light 100, but also avoids the light from being too dazzling due to too high light transmittance of the light-transmitting plate 12.
[0039] Furthermore, a frame 121 is provided at the edge of the light-transmitting plate 12. The frame 121 is connected to the rear cover 30 and cooperates to enclose the accommodating cavity. The frame 121 can further prevent light from leaking out and also increases the space of the accommodating cavity in cooperation with the rear cover 30.
[0040] It can be understood that the frame 121 can be formed by folding the edge of the light-transmitting plate 12, and a light-shielding material is applied on the frame 121 to achieve the effect of blocking light. The frame 121 can also be directly provided with a flanging and connected to the light-transmitting plate 12 by means of welding or bonding.
[0041] A plurality of heat dissipation holes 32 are formed in the rear cover 30. The heat dissipation holes 32 are arranged at uniform intervals to facilitate the rapid dissipation of the heat generated by the light-emitting strip 40 to the external environment through the heat dissipation holes 32. There are a plurality of heat dissipation holes 32, and they are arranged at uniform intervals along the length direction of the rear cover 30, so as to adapt to the extension direction of the light-emitting strip 40 in this application and improve the uniformity of heat dissipation.
[0042] A protrusion 31 is also provided on the rear cover 30. The protrusion 31 abuts against the side of the light-emitting plate 20 facing away from the font plate 10 to keep the light-emitting plate 20 in an upright state (when it is installed parallel to the front side of the medical device), and the position is more stable.
[0043] The protrusion 31 is preferably made of a soft material, such as plastic or rubber, etc., to avoid scratching the light-transmitting plate 12.
[0044] The present utility model also provides a medical device, including the indicator light 100 as described above and a device main body. The indicator light 100 is installed in the device main body, and the light-emitting plate 20 is electrically connected to the device main body through a shielding joint 50. Since the device main body generates radiation during operation, the shielding joint 50 can shield the radiation and protect the cable to extend the service life of the cable.
[0045] Compared with the prior art, by providing the diffusion plate 22 and the light homogenizing plate 21, the present utility model enables the light emitted from one light-emitting strip 40 to be evenly scattered after passing through the diffusion plate 22 and the light homogenizing plate 21, reduces energy consumption, reduces heat generation, and makes the light-emitting font on the indicator light 100 display more evenly. In addition, a plurality of pits are formed in the diffusion plate 22 to further improve the ability of the diffusion plate 22 to change the light propagation direction, so as to make the light propagation more uniform.
[0046] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0047] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
