LED street lamp working principle description, use precautions
What is the working principle of LED street lights? What should we know about the use of LED street lights? Below, we will sort out and introduce the working principles and precautions of LED street lights. Low maintenance cost of LED street lights: Compared with traditional street lights, the maintenance cost of LED street lights is extremely low. After comparison, all input costs can be recovered in less than 6 years. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements of different periods. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent. There is a serious shortage of power supply, and energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting.
First of all, let us understand the working principle of LED street lights. LED street lights are based on the principle of photovoltaic effect of solar cells. During the day, solar cells absorb solar photon energy to generate electrical energy, which is stored in the battery through the controller. When night falls or the brightness around the street lamp drops to a certain value, the controller will perform its own discharge operation and turn on the street lamp to start lighting. Therefore, when choosing and purchasing LED street lights, different regions must pay special attention to whether the design ideas and key points of the system are in line with the actual local conditions. Not only must it save investment while pursuing low prices, but also not blindly pursuing high performance and causing waste of resources. .
Precautions for the use of LED street lights
1. The LED street light device should always be installed in sunny weather. If it is installed on a cloudy or rainy day, it only consumes electricity and does not charge after lighting, it does not meet the description requirements. The LED street light installation should not be lit on the day it is completed.
2. The angle of the LED street light panel is usually 45 degrees to describe the manufacturer, so as to have a good charging capacity in the winter when the tube is packaged.
3. Connection of LED street light controller. Waterproof controllers should be used as much as possible to ensure that long-term stability remains together and to prevent users from changing the lighting time at will. If a non-waterproof controller is used, the wiring is bent into a U shape with the junction box facing downwards, which prevents water from flowing into the controller from the wiring.
