In view of the present situation of high energy consumption, easy loss, difficult maintenance and hidden danger of small old-fashioned lighting lamps, which have been installed in factories, campus and residential areas, this paper proposes to use the main body of retaining the original power supply line and street lamp, and to solve the above problems by adding LED controller and replacing the LED hair light.

Parameter comparison and power selection of LED light source and traditional light source

At present, the light source used for the small street lamps used for many years is varied and different in performance. The next table is the comparison of the technical parameters of the LED light source and the various traditional light sources.

By comparing the comprehensive comparison of the technical parameters of various light sources and the comparison of the actual effects, it is found that the LED light source has high luminous efficiency, good color performance and the longest service life. The LED of 70W can replace the high pressure sodium lamp of 250W, or the mercury lamp of 300W can achieve 70% energy saving. Therefore, when choosing the power of LED light source used for transformation, we can use the 1/3 of the existing light source power as the reference standard.
Design and implementation of road lamp reconstruction scheme
This paper mainly discusses the reconstruction scheme of small street lamps. Small street lamps are characterized by low lamp body height (3~6 meters high in general light), diversified structure forms (not only simple integrated lighting lamps, but also complex and changeable landscape lamps), so the reform plan should be designed according to the specific configuration of the original road lamp system. We should not only consider the body structure of the original street lamp and the beauty of the transformation, but also consider the control of the transformation cost and the maximum utilization of the existing resources. Therefore, the design principles of the road lamp reconstruction plan are: (1) not changing or changing the appearance of street lamps; (2) making full use of the original road lamp line and installation structure (to maximize the reuse of resources); (3) making full use of the diversity of LED products (red, yellow, blue, green, white and many other luminous colors, various types of lamps, different power lamps) Many kinds of products, such as beads, various types of light bulbs, etc. In order to meet the needs of transformation, it is necessary to use the LED lamp bar or the luminescent body according to the inner structure of the street lamp, and to realize the time sharing control (busy and half bright in busy time) considering the energy saving and environmental protection factors.
In order to make full use of resources, we can adopt the step by step transformation method. First of all, the original road lamp is dismantled and tested, and the light source and accessories that still have the value of use are concentrated to repair some street lamps so that their work will be reformed after the natural damage; the rebuilt street lamps are first reformed and the reformed records are made well. Since the total power of the road lamp is reduced by more than 50%, we can make full use of the three phase lines in the original line to carry out the control. Through the time controller, we can easily realize the control of any switch of the light double light or even the three light source, which is not only conducive to the realization of energy saving and consumption reduction, but also greatly prolongs the life of the LED street lamp. Life.
After the transformation of the street lamp is completed, the energy saving comparison table can be formed through the recorded data of the pre power consumption.
summary
According to this scheme, an activity center has completed 60 road lights transformation, the original road lamp 120W gold halogen light lamp is replaced by the 30W LED spotlight, and the dome light and pole light are controlled by time - to - point control, the theodolite street lamp controller controls the ceiling light switch, the pole lamp is controlled by the time controller for the night 6 to 12 point light, after 12 points closed, the classic More than 75% of energy saving is realized. The successful case proves that the LED street lamp transformation plan is feasible and has certain guiding function in transforming the old street lamp into LED street lamp.
