And solar road studs can light from dusk to dawn even in demanding environments such as Northern European winters. Intelligent, interactive technology detects human traffic and increases illumination, then automatically powers down to a lower level to conserve energy when no movement is detected which also reduces light pollution.
Under what conditions are solar road studs widely used? As the focus of expressway construction is gradually shifting to mountainous areas and the mountainous areas with relatively backward economic development, fog often occurs in mountainous areas. Drivers are afraid to drive in the fog area, because they can not predict the linear direction of the road, which is very easy to cause traffic accidents. The solar road stud can prevent the driver’s vision from darkening and the visibility from greatly decreasing.
Solar road studs are known to be commonly used on roads or highways, but our Canada customers have purchased solar road stud installed on lake bridges as solar dock lights that outline the bridge’s edge. At night, solar road stud are a good reminder to pedestrians. Solar road stud look very beautiful at night.
Solar road studs can effectively improve the road safety line through lighting. The large turntable of Puxi main approach bridge of Nanpu Bridge is a section where traffic accidents occur frequently. In order to reduce the incidence of accidents and ensure driving safety, the project Department of Nanpu Bridge recently installed solar road studs on the right inspection road from west to east of Puxi main approach bridge.
Solar road stud is a kind of road stud, which is set along the road surface. It is used to indicate the direction of the road at night or in rainy and foggy weather. It is composed of retroreflective material, shell, solar panel, led and controller. It is a visual guidance facility with active light-emitting and passive reflective performance. It is usually used in combination with marking.
Today we are going to talk about the solar road stud for the design concept, in the ordinary road stud improvement, increased the setting of LED lights. Compared with the ordinary road stud, the solar road stud has the characteristics of active lighting, can better point out the direction in the dark.
Solar road stud is to rely on solar energy resources for power generation. Therefore, the application of solar road stud not only does not need to lay the circuit, construction wiring, but also can effectively save resources. The saving of power resources is conducive to the sustainable development of the environment and the further reduction of production costs. From the application of energy, solar road stud is very advantageous.
During the summer in full direct sunlight, solar road stud can take up to 8 hours to full charge. Partial sunlight/shaded areas will extend the charging period of solar road stud. For installation of solar road stud during winter months and in cloudy conditions the charging time will be extended.
Why should the power supply of LED outdoor solar road stud lighting be constant current? The characteristics of LED lighting materials determine that led outdoor solar road stud lighting is greatly affected by the environment. For example, when the temperature changes, the current of LED outdoor solar road stud lighting will increase. With the increase of voltage, the current of LED outdoor solar road stud lighting will also increase.
The design LED outdoor solar road stud lighting has a rated current of 350. In fact, the heating is very serious under this current. After many comparative tests, the design of 320 Ma is ideal. Try to reduce the heating value of LED outdoor solar road stud lighting and turn more electric energy into visible light energy.
What is the working current of LED outdoor solar road stud lighting power supply? For example, the rated working current of LED outdoor solar road stud lighting is 350 ma. Some factories carry out LED outdoor solar road stud lighting design, which will be exhausted at the beginning.
The LED outdoor solar road stud lighting current is too large, and the voltage is too small, which should be avoid. Or the LED outdoor solar road stud lighting current is too small and the voltage is too high. The result is that the LED outdoor solar road stud lighting has serious heating, low efficiency, or insufficient input voltage range.
