Traffic light and method and device for controlling arrangement and arrangement of lamp beads on traffic light

Abstract

The invention discloses a traffic light and a method and device for controlling arrangement of light beads on the traffic light. The traffic light comprises a circular light panel and a plurality of light-emitting assemblies evenly arranged in all fan-shaped areas of the circular light panel in the circumferential direction. Each light-emitting assembly comprises a first linear light-emitting body, a second linear light-emitting body and a third linear light-emitting body which are formed by electrically connecting a plurality of lamp beads in sequence; the first linear light-emitting body isarranged on the central axis of the fan-shaped area, and a first preset distance is formed between the end of the side, close to the circle center, of the first linear light-emitting body and the circle center; the second linear light-emitting body and the third linear light-emitting body are symmetrically arranged on the two sides of the central axis and form preset angles with the first linear light-emitting body. The distance between the ends of the sides, close to the circle center, of the second linear light-emitting body and the third linear light-emitting body is smaller than that between the ends of the sides, away from the circle center, of the second linear light-emitting body and the third linear light-emitting body. The utilization rate of the lamp beads can be increased, and the light-emitting effect of the lamp beads is enhanced.

Description

technical field [0001] The invention relates to the field of traffic equipment, in particular to a traffic light and a method and device for controlling the arrangement and arrangement of lamp beads on the traffic light. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Since the power and brightness of LED lamp beads are not very high at present, and the actual use usually requires plane light emission, it is necessary to arrange and combine multiple LED lamp beads according to needs to meet the needs of larger range, higher brightness, dynamic display, Application requirements such as color transformation. Taking a traffic light with a circular outline as an example, a circular light panel is often arranged inside the traffic light to arrange various lamp beads, and each lig...

Problems solved by technology

[0006] The embodiment of the present invention provides a traffic light, which is used to solve the technical problems of the existing traffic light, that the lamp beads arranged on the circular light board are arranged in a straight line along the radius of the radius, the utilization rate of the lamp beads is low, and the luminous effect is poor. The traffic light includes: a circular light board and a plurality of light-emitting assemblies uniformly arranged in each fan-shaped area of ​​the circular light board along the circumference; each light-emitting assembly includes: a first straight line formed by a plurality of lamp beads A linear illuminant, a second linear illuminant, and a third linear illuminant; wherein, the first linear illuminant is arranged on the central axis of the fan-shaped area, and the first linear illuminant is placed between the end near the center of the circle and the center of the circle. There is a first preset distance between them; the second linear light emitter and the third linear light emitter are symmetrically arranged on both sides of the central axis in the fan-shaped area, and respectively form a preset angle with the first linear light emitter; the second linear light emitter The distance between the end of the third linear illuminant near the center of the circle is smaller than the distance between the second linear illuminant and the end of the third linear illuminant on the side away from the center of the circle;

[0009] The embodiment of the present invention also provides a method for controlling the arrangement of lamp beads on traffic lights, which is applied to the above-mentioned traffic lights to solve the problem of existing traffic lights. The lamp beads arranged on the circular lamp board are arranged in a straight line along the radius , there are technical problems of low utilization rate of lamp beads and poor luminous effect. The method includes: receiving externally input configuration parameters, wherein the configuration parameters include: the radius of the circular lamp panel, the lamps to be arranged on the circular lamp panel The number of beads and the luminous radius of a single lamp bead; according to the radius of the circular lamp panel, the number of lamp beads to be arranged on the circular lamp panel and the luminous radius of a single lamp bead, determine the fan-shaped area on the circular lamp panel Number; according to the number of fan-shaped areas on the circular light board, the radius of the circular light board and the luminous radius of a single lamp bead, determine the first linear light emitter, the second linear light emitter and the third straight line in each fan-shaped area The number of lamp beads contained in the illuminant; according to the number of fan-shaped areas on the circular light board, and the number of lamp beads contained in the first linear illuminant, the second linear illuminant and the third linear illuminant in each fan-shaped area Number, control the arrangement of each lamp bead on the circular lamp board
