in recent years, energy conservation has become the people talking about the topic, in terms of lighting, has taken some measures to energy saving, follow high lamp manufacturers to know about the below. 1, light and energy saving. Light energy saving depends mainly on its luminous efficiency, but the selection of light sources can't simply from photosynthetic efficiency, and should according to the colour developing index, service life, start the characteristics such as comprehensive consideration, reasonable use. Choose the principle of light source: minimize the incandescent light bulb use; Promote the use of thin tubular fluorescent lamps and compact fluorescent lamps; Gradually reduce the use amount of high pressure mercury lamp, LED street lamp, especially should not be free to use the ballast and high pressure mercury lamp; Actively promote high pressure sodium lamp, metal halide lamp. 2, choosing a energy-saving lamps and lanterns: choose lamps and lanterns should consider the following aspects: should have a higher utilization coefficient; Choose the lamp light distribution; First choose piece of plate type lamps and lanterns; As far as possible choose not to bring the lamps and lanterns of accessories; As far as possible choose lamps and lanterns with high retention rate. Lamps and lanterns is very important to energy saving performance, the main is the role of lamps and lanterns and light distribution efficiency. Efficiency is under prescribed conditions of lamps and lanterns lighting lamps and lanterns of optic FL interacts with all of the light source inside the launch of the total light outside the lamps and lanterns lit when the ratio of the FS, expressed with 'h', or h = FL/FS. Generally speaking, h with lampshade material is directly proportional to the reflectance and transmittance, open the efficiency depends on the open area of lamps and lanterns of lamps and lanterns S0 and reflection area S ratio and the shape of the reflector. In order to minimize the losses in the lamps and lanterns lamplight, S0 / S very big time. The shape of the reflector main cause light multiple reflections in the chimney. 3, time and number of energy saving. Road lighting should be comprehensive promotion in the middle of the night lights, primary and secondary trunk road double circuit power supply, full night light loop and the modulation circuit in the middle of the night, unconditional offer special lamp circuits can be used in the middle of the single-phase power supply in the middle of the night, but should make the whole balance of three phase; Branch, industrial and living area, road way narrow streets using unilateral change in the middle of the night lights. City lights only commonly more residents outdoor activities in the session open. 4, circuit compensation and energy saving. Single light compensation is a capacitance in parallel on each lamp appropriate capacitor to compensate, both to reduce the reactive power of the lighting circuit, also can reduce the power loss and voltage loss on the road in the low-pressure flare path. At the same time, because the line current is reduced, can choose a smaller cross section of conductor. Single light compensation experience value: 250, 400 w high pressure sodium lamp compensation capacitor value of 30 and 50 uf respectively. Concentration is focused capacitance compensation in a power distribution unit, its advantage is easy installation, reliable operation, high utilization, the disadvantage is that does not reduce the voltage loss and power loss of low-tension wire road, only plays a role of reactive power compensation for grid. In addition, the equipment must be equipped with discharge. Line 5, energy saving. According to the formula S = I / [In Cable sectional area for type of S ( mm2) And I for the street light load current ( A) Current density, as In the economy, A/mm2) ] Select cable, the resistance to reasonable value, so as to decrease the line loss.
