traffic lights manufacturers mdashmdash siao traffic equipment co. , LTD. , analyzing the traffic lights have the following: startup and shutdown time. In light-emitting diodes, traffic lights, power adapter energy storage components for the design and use undeserved, can cause the same group or the same direction of light emitting units out of sync, can't correct response signal output signal, and may even lead to signal an error. In order to ensure the signal and the signal output signal is consistent, the 2011 version of the standard reference the related provisions of Australia and the United States about led lights, regulation light emitting unit start-up response time shall not exceed 100 milliseconds, close the response time shall not exceed 100 milliseconds. Working voltage range. According to the present situation of our mains and the requirements of the relevant foreign standards, 2011 standard will be the normal work of the light voltage range from several dozen times the rated working voltage change for dozens of times. 15% to plusmn20 %, and require a reference on the shaft of light intensity fluctuation is less than 10% of the rated voltage. At the same time, the phase of light is to avoid the phenomenon of light shine, 2011 version of the standard regulation, in the case of a power supply voltage is not more than 90 v, lights shall not emit any visible light. 2011 version of the standard to the energy consumption of different kinds lights product test data as the foundation, elaborated the light-emitting diode light source lamp power requirements, put forward different specifications for design of light power requirements. The instantaneous current. In order to avoid the light starts the influence of the signal ( The fuse may fuse or light may be mistaken for failure) , 2011 version of the standard lamp startup current should not be greater than 2 a. In the process of actual test, simulation soft switch is used to start ac 50 hz sinusoidal wave signal, in order to avoid the mechanical switch opens instantaneous impact current. Road traffic signal lights as terminal, in improving city intersection traffic efficiency, to prevent and reduce traffic accidents, play an active role in ensuring traffic safety and unimpeded. The national standard 'the road traffic lights' ( GB14887- 2011). Issued and implemented, will improve the quality and technical level of light to a new level, to better safeguard urban road safety and unimpeded.
