Solar energy traffic signal system

Abstract

The invention discloses a solar energy traffic signal system comprising a digit post drive motor 1, a digit post 2, a sign post 3, a light shielding ring 4, an LED 5 and a sign post drive motor 6, wherein the digit post drive motor 1 is powered by the photoelectric conversion electric energy of a solar energy photovoltaic cell and turns pages of the digit post 2 in backward sequence in a count down way of the prior traffic signal system during work; when the digit post drive motor 1 turns the pages to a preset value, the sign post drive motor 6 starts to overturn the sign post 3 to prompt passing or no passing, and electric energy adopted by the sign post drive motor 6 is also the photoelectric conversion electric energy from the solar energy photovoltaic cell. In order to ensure night traffic signal indication, the LED 5 with low electricity consumption is used for illumination, and when the temperature is lower than a certain value, a light-operated switch conducts the LED 5 for theillumination. The invention has reliable property by adopting a developing way to display digits and signs and omits the power supply line distribution on the basis of electricity saving by using single solar energy, thereby not only achieving the energy saving effect but also saving the heavy investment.

Description

Technical field [0001] The invention relates to a traffic signal system, particularly a solar traffic signal system. technical background [0002] Since the 1950s in my country, some large cities and medium-developed cities have begun to use colored incandescent lamps as traffic lights. It uses alternating current and uses a simple switch to control the indication of traffic lights. This traditional traffic signal indication mode and its improved products have been used as the first generation of traffic lights for nearly half a century. It has incandescent bulbs and large heat sources. The shortcomings of power consumption, low brightness, fragility, etc., in the early 1990s, with the widespread popularization of LED products and technologies, it was the first to be adopted by traffic lights with its advantages of high brightness, long life, and low power consumption. The LED traffic signal lamp is a combination of several LED components in accordance with the requirements of t...

AI Technical Summary

Problems solved by technology

[0003] 1. Use 220 volts or 380 volts of alternating current. Before installation, it must first erect power lines, lay underground cables and related power supply facilities. The construction period is long and the cost is high;

[0004] 2. The aging leakage of wires and cables is likely to cause power loss and electric shock accidents, and it is necessary to regularly replace and overhaul the power supply control facilities;

[0005] 3. The LED display and control part is greatly affected by the grid voltage fluctuation and interference, the system is easily damaged, needs to be maintained and replaced at any time, requires fixed maintenance personnel, and there are frequent parts costs;
