Ordinary street lamp into the LED street light is not very hard
According to the present has been installed in the factory, school district, residential areas, such as the location of the high energy consumption of the small old lighting lamps, vulnerability and difficult maintenance, unsafe situation, this paper proposes using retained the original power lines and street lamp body, by increasing the LED controller, LED street light emitting device, method of replacement to solve the above problems.After one activity center example show that this scheme is feasible and energy saving effect is obvious.
Currently installed using years of small street lamp light source is varied, different performance, based on comprehensive comparing all kinds of light source technology parameters and the actual use effect on the control of the detection, LED light source, high luminous efficiency and color rendering performance is good, using life expectancy, 70 w leds can replace 250 w high pressure sodium lamp, mercury lamp or 300 w, can realize energy saving more than 70%.So when choosing reconstruction using LED light source power, to a third of the existing light source power as the reference standard.
This article mainly discuss the retrofit scheme of small street lamp.Small street light with the light body height shorter (general lamp in 3 ~ 5 meters high), the structure form of diversification (both simple integrated lighting lamps, and appearance of the complex landscape lamps), etc, so the retrofit scheme to design according to the specific configuration of the original street lamp systems.Should not only consider the original street light lamp body structure and beautiful degree of the revamp, also want to consider the cost control and the maximum use of existing resources.Therefore, rebuild design of street lamp principle is: (1) does not change or less street lamp appearance;(2) make full use of the original street light lines and installation structures (maximum realize resource recycling);(3) make full use of the diversity of LED products (with red, yellow, blue, green, white and other light color, with each article lamp, lamp bead, different power each bulb product in the form.)To meet the needs of the transformation, if necessary, need according to the internal structure using article LED lights or lamp bead homemade light;(4) considering energy conservation and environmental protection factors, realize time-sharing control (busy hour on, half bright) when.
Plan implementation process, to make full use of resources, we can use fractional transformation method.First to disassemble the lamps of the primary test, are useful light and accessories together to repair part of the street lamp, make its work to the transformation of the reentry after natural damage;Can't repair the street lamp is first of all, and make records.Due to the modified street lamp fell more than 50% of the total power, so we can make full use of the original branch control circuit of three phase line, through can controller is easy to implement on the street lamp any switch control of double light source and three light source, it is not only beneficial to realize saving energy and reducing consumption, greatly extend the service life of LED lights.
According to this scheme, an activity center has completed 60 street light transformation, the original street light 120 w metal halide lamp dome light for 30 w LED spot light, original 40 w daylight lamp pole lamp 2 root for cylinder made of white article 5050 leds lamp (power of 20 w), and the dome light and light to realize time-sharing control, controlled by the theodolite street lamp dome light switch, light is controlled by the time controller for 6 ~ 12 lights at night, shut down after 12 o 'clock, the statistics to realize energy saving more than 75%.More successful cases prove that this retrofit scheme feasible LED street lamps, in reforming the old street lamp LED lights have a certain guiding role in the proce
