Definitions

  • the present invention relates to a traffic indicator, especially to a traffic indicator that is capable of displaying different types of traffic lights and symbols with a remaining time indication.
  • the traffic signs mainly comprise dynamic type and static type.
  • the static traffic signs such as road signs, are suitable for indicating traffic rules or speed limitations.
  • the dynamic traffic signs are often composed of lights, for instance, the traffic lights or pedestrian lights.
  • the present invention provides a traffic indicator to mitigate or obviate the aforementioned problems.
  • the main objective of the present invention is to provide a single traffic indicator capable of simultaneously displaying the traffic lights, traffic symbols and countdown information depends on practical requirements at different crossroads.
  • the traffic indicator has a base, a circuit board mounted in the base, an LED panel mounted in the base and a protect lid. Based on the control of the circuit board, the LED panel composed of multiple LEDs of different colors is able to display different traffic lights as well as traffic symbols. In other words, a single display screen can show red, green or yellow traffic lights, moving direction symbols and countdown information. Since the traffic indicator has only one display screen, the traffic symbols can be displayed in a larger size so that drivers can easily recognize the traffic symbols. Furthermore, to compare with the conventional LED-based traffic light equipped with multiple display screens, the traffic indicator with only one display screen requires less fabricating and upkeep costs.
  • Another objective of the present invention is to provide a function of adjusting brightness of the traffic indicator.
  • the traffic indicator uses an optical sensor to detect the intensity of light of surroundings. Based on the detected result, the circuit board can accordingly adjust the brightness of the LEDs on the LED panel.
  • a traffic indicator (10) in accordance with the present invention comprises a base (11), a circuit board (12), an LED panel (13) and a protect lid (14).
  • the protect lid (14) can be made of translucent or transparent material and is mounted on the base (11) to cover the circuit board (12) and the LED panel (13).
  • a control circuit on the circuit board (12) for the traffic indicator (10) comprises a control unit (121), an output connecting interface (122), a timer (123), an input device (124) and an optical sensor (125).
  • the output connecting interface (122) is connected between an output terminal of the control unit (121) and an input terminal of the LED panel (13). Through the output connecting interface (122), the control unit (121) can turn on or turn off each of the LEDs, and controls their color and brightness.
  • the timer (123) has an output terminal connecting to the control unit (121) and an input terminal connecting to the input device (124).
  • the input device (124) can be a key set or a switch set, and has output terminals respectively connecting to the control unit (121) and timer (123) for setting operation parameters to the control unit (121) and timer (123).
  • the optical sensor (125) connected to the control unit (121) detects the intensity of the light of the surroundings. The detected result is transmitted to the control unit (121). Based on the detected result, the control unit (121) can adjust the brightness of LED panel (13).
  • the LED panel (13) is mounted in the base (11) and electrically connects to the circuit board (12).
  • the LED panel (13) comprises multiple light emitting diodes (LEDs) of different colors thus, the circuit board (12) can control the LED panel (13) to display red, yellow or green light in a large-area to form a traffic light.
  • the LED panel (13) has two display regions.
  • the first display region is an outer ring region (131).
  • the second display region is a center circular region (132) within the outer ring region (131).
  • the outer ring region (131) provides a function of countdown.
  • the entire outer ring region (131) can be divided into sixty sections corresponding to sixty seconds of a clock.
  • the center region (132) displays a tragic symbol or a sign
  • the originally activated sixty sections of LEDs in the outer ring region (131) can be either sequentially turned off in a counterclockwise direction to show the remaining seconds or sequentially turned off for one second in a counterclockwise direction to generate a visual effect of a moving dot.
  • the sixty sections of LEDs in the outer ring region (131) are sequentially turned on for one second in a counterclockwise direction to generate a visual effect of a moving light dot as a moving second hand.
  • the displayed color of the outer ring region (131) is subj ected to the color of center region (132).
  • the countdown of remained time may be less than 60 seconds or longer than 1 minute subjected to the traffic load at crossroad but the countdown indications above are activated well while the setting of countdown is less than 61 seconds.
  • the center circular region (132) can display all desired patterns of traffic symbols as long as these patterns are pre-set or pre-programmed in the circuit board (12). For example, the center region (132) shows a right turn symbol on Fig. 4 , a right/left turn symbol on Fig. 5 and a left turn symbol on Fig. 6 . Accordingly, the direction indications above can either illuminate right/left turn symbols alone as a direction indicator or black out the right/left turn symbols when the center circular region (132) lights up as a traffic light.
  • a single traffic indicator in accordance with the present inventions is able to display all desired patterns of traffic symbols based on the pre-set or pre-programmed settings in the circuit board (12) to meet different requirements of the crossroads. Therefore, the conventional traffic lights can be reduced to one single traffic indicator.
