With the rapid development of solar photovoltaic power generation technology, solar street lights have quickly been promoted and applied in the vast cities and rural areas, especially in the rural areas without power grids, and have achieved success. At the same time, many electricity has been installed Solar street lights have also begun to be installed on the urban roads of the route, but these roads are different from rural roads. If they are designed in the same way, on the one hand they cannot meet the requirements of urban road lighting, on the other hand, it also causes a waste of resources. Therefore, the utility power complementary solar street lamp can solve this situation well. The utility power complementary solar Led Street Light is composed of solar panels, Solar Street Light controllers, batteries, lighting fixtures, consoles and power communication lines. Its advantages are very obvious. The following editor will introduce to you what its advantages are:

1. It can greatly reduce the cost of dual power supply for street lights in urban areas, reduce energy consumption, and conform to the concept of green and environmental protection.
2. Turn on the lights 365 days a week. Normal solar street lights are generally unable to keep on for multiple rainy days because of battery capacity and battery panel power design issues. The complementary solar LED street light from the mains can be automatically switched to the power source during rainy days, ensuring that the lights are on every day for 365 days.
3. Improve the service life of solar batteries. Complementary solar street lights with commercial power can reduce the number of cycles of solar batteries to a limited extent, which will inevitably increase the service life of batteries.
4. There is no need to arrange additional communication lines, and the cost is low, the communication error rate is low, it is not easy to be interfered, and large-scale networking control can be carried out.
The above are the advantages of complementary solar street lights. When we use them, we must adapt to local conditions, use them rationally, and match them reasonably to give full play to its good lighting effect.

With the continuous development of solar energy technology, Solar Street Light products are becoming more and more popular. Many rural areas have installed solar street lights, but there are many things to pay attention to when installing solar street lights, especially when choosing installation sites and pre-embedded foundations. Will pay attention, so the use of solar street lights is not good, so what should we pay attention to when choosing the installation location and pre-embedded foundation?

1. Choice of installation location
The installation site must have sufficient sunlight throughout the day, without any obstructions. Make sure that the installation site is far away from trees, high-rise buildings and other obstacles that will block the sun. There should be no direct light source above the Solar Panel, otherwise the street light system will not work properly. Solar street lights must be far away from heat sources , Otherwise the battery life will be greatly shortened. The foundation of the solar Street light pole must be poured in a sufficiently solid clay layer. If the installation site is atypical soil layers such as sand or frozen soil, please inform us in advance so that we can take specific countermeasures. The solar panels must face south and ensure that the installation site faces south without obstructions.
2. Building the foundation
Ensure that the inner test nut is screwed to the end of the thread, and leave enough length for the flange of the solar street light pole to ensure that the four bolts are on the same horizontal line. It is recommended to use a level to test and assemble the upper end of the thread with tape to prevent cement blockage Thread.
Three, installation basis
Dig the foundation pit according to the basic map provided by the solar street light manufacturer. At the same time, concrete can be prepared. Put the basic cage into the foundation pit, use a level to ensure that the basic cage is placed horizontally, and compact the basic cage. Make sure that the upper thread of the anchor bolt is protected by tape. Pour the concrete and keep the level of the foundation cage. It is recommended that the concrete just cover the fixing plate and the nuts on it to prevent it from rusting. Clean the top of the foundation and level it with a trowel. After 3-7 days, confirm that the concrete is completely solidified and dry, and then remove the insulating board/brick.
The above are the items that need special attention in the installation of solar street lights. We must pay attention to the installation to avoid the phenomenon of non-lighting or poor lighting effects.

The courtyard lamp is an indispensable part of modern residential lighting. It not only has a high degree of viewing, but also harmonizes with the surrounding environment of the residential area. Courtyard lights use different shapes, different light colors and brightness to create scenery. So why does the community need to install courtyard lights?

2. The courtyard lights highlight the main landscape at night and can form a virtual and actual relationship with the surrounding environment of the community, enriching the night view of the community.
Fourth, the courtyard light has the function of marking and reminding. The specific light can remind you about which area of the community.
As mentioned above, it is necessary to install courtyard lights in the community. Generally, the height of the courtyard lights in the community is 3~4 meters, which is more in line with the night landscape of the community. The courtyard lamp is an indispensable part of modern residential lighting. It not only has a high degree of appreciation, but also harmonizes with the surrounding environment of the residential area. Courtyard lights use different shapes, different light colors and brightness to create scenery. Then, the height of the courtyard lamp is more in line with the night landscape of the community.
