Description

Technical Field

[0001] The present invention relates to the technical field of warning lights, and in particular to a multi-layer warning light adaptive dimming control device and method. Background Art

[0002] In factory workshops, warning lights are used to indicate the operating status of equipment. For example, when a device fails, a red warning light may light up to remind staff that the device needs maintenance. Some automated production lines use warning lights of different colors to indicate different production conditions. Green indicates normal operation, yellow indicates that attention is needed, and red indicates a failure or emergency stop.

[0003] During use of the existing warning light, the color of the warning light changes according to the color of the lampshade. However, since the light of the LED light inside the warning light is scattered at other positions during use, the staff may make a misjudgment. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problem and to propose a multi-layer warning light adaptive dimming control device and method.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: comprising a mounting frame, a lampshade is mounted on the upper end of the mounting frame, a sealing cover is rotatably mounted on the lower end of the interior of the lampshade, a condenser is rotatably mounted on the upper end of the interior of the lampshade, a plurality of groups of luminous bodies are mounted in the middle of the condenser, a sounding body is mounted on the lower end of the luminous body at the lowest end, a connecting piece is mounted on the lower end of the sounding body, a mounting tube is mounted on the lower end of the sounding body, and a light-emitting control circuit is mounted inside the lampshade;

[0006] The connecting piece comprises a protective cover installed at the bottom of the lampshade, two groups of L-shaped conductive columns are installed inside the protective cover, the two groups of conductive columns are fixed to the bottom of the lampshade, the upper ends of the two groups of conductive columns are respectively fixedly installed with sealing covers, the outer surface of the mounting tube is fixedly installed with a connecting tube used in conjunction with the sealing cover, a sliding conductive ring is fixedly arranged inside the connecting tube, an outer conductive ring and an inner conductive ring used in conjunction with the sliding conductive ring are fixedly arranged at the lower end of the sealing cover, the outer conductive ring and the inner conductive ring are both connected to the conductive column, the sealing cover is rotatably connected to the mounting tube and is provided with a sealing ring, sealing rings are respectively provided between the sliding conductive ring and the outer conductive ring and the inner conductive ring, mercury is filled between the inner conductive ring and the outer wall of the mounting tube, a U-shaped conductive wire is fixedly provided at the lower end of the sliding conductive ring, a guide wire is connected to the middle position of the U-shaped conductive wire, and the guide wire is respectively connected to the light-emitting body and the sound-emitting body, a motor is installed inside the mounting frame, and the motor output shaft is connected to the lower end of the mounting tube;

[0007] In actual applications, when the motor output shaft drives the mounting tube to rotate, the mounting tube drives the connecting tube to rotate, the connecting tube drives the sliding conductive ring to rotate, the sliding conductive ring slides with the outer conductive ring and the inner conductive ring, thereby stably transmitting electricity. At the same time, mercury is filled between the inner conductive ring and the outer wall of the mounting tube. Mercury is an excellent conductor with a very low resistivity, which can effectively reduce power loss and further improve conductivity.

[0008] Further, the condenser cover comprises a rotating cover rotatably connected to the lampshade, a plurality of condenser strips are fixed on the inner wall of the rotating cover from top to bottom, a cover plate is fixedly arranged on the upper end of the rotating cover, the cover plate and the uppermost luminous body are detachably mounted, the focal points of the condenser strips are different, there are gaps between the condenser strips, a light-isolating plate is arranged between the luminous bodies, and the surface of the light-isolating plate is coated with reflective paint;

[0009] In actual application, since a plurality of focusing strips are fixed on the inner wall of the rotating cover from top to bottom, and the focal points of the focusing strips are different, the light can be concentrated at different positions through the focusing strips, so that people at different positions can clearly observe the light. At the same time, the rotating cover can drive the focusing strips to move during the rotation process, so as to better remind the staff, and light isolation plates are arranged between the light sources, so as to effectively separate the three layers of light sources and prevent the staff from misjudging the color of the light.

[0010] Furthermore, a sound outlet hole is provided on the outer wall of the sealing cover, and a through hole is provided at the lower end of the lampshade to cooperate with the sound outlet hole;

[0011] In practical applications, when the sound outlet hole and the through hole are superimposed together, the sound emitted by the sound-emitting body can be better transmitted, and when the sound outlet hole and the through hole are staggered, external water vapor can be prevented from entering the warning light.

[0012] Furthermore, a method for a multi-layer warning light adaptive dimming control device is provided, wherein the light control circuit includes a current adjustment circuit for preventing the current from being too large or too small, a step-down circuit, a pulse output circuit, a control circuit, a switch circuit, a light-emitting body, and a rectifier and filter circuit for providing a stable operating voltage to the above-mentioned circuits; the step-down circuit is electrically connected to the output end of the rectifier and filter circuit, the output end of the step-down circuit is electrically connected to the input end of the pulse output circuit, the output end of the pulse output circuit is electrically connected to the input end of the control circuit, the output end of the control circuit is electrically connected to the input end of the switch circuit, and the output end of the switch circuit is electrically connected to the light-emitting body; the input end of the current adjustment circuit for preventing the current from being too large or too small is electrically connected to the output end of the rectifier and filter circuit, and the output end of the current adjustment circuit is electrically connected to the light-emitting body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the motor output shaft drives the mounting tube to rotate, the mounting tube drives the connecting tube to rotate, and the connecting tube drives the sliding conductive ring to rotate, the sliding conductive ring slides with the outer conductive ring and the inner conductive ring, thereby stably transmitting electricity. At the same time, mercury is filled between the inner conductive ring and the outer wall of the mounting tube. Mercury is an excellent conductor with a very low resistivity, which can effectively reduce power loss, thereby further improving conductivity.

[0015] Since a plurality of focusing strips are fixed on the inner wall of the rotating cover from top to bottom, and the focal points of the focusing strips are different, the light can be concentrated at different positions through the focusing strips, so that people at different positions can clearly observe the light. At the same time, the rotating cover can drive the focusing strips to move during the rotation process, so as to better remind the staff. Light isolation plates are arranged between the light sources, so as to effectively separate the three layers of light sources and prevent the staff from misjudging the color of the light.
