Abstract

The utility model discloses an energy-saving street lamp, which comprises radiators and a plurality of parallel arranged linear or U-shaped fluorescent lamp tubes. The radiators are disposed at one end or two ends of each linear or U-shaped fluorescent lamp tube. The passive heat dissipation technique prolongs service life of street lamps, lowers energy consumption, saves energy, and realizes fine light source quality. Electronic ballasts applied to the street lamps are beneficial to compensating power factor reduction caused by excessive inductive electric appliances in a power grid, thereby increasing quality of the power grid. Each lamp tube is individually provided with a parabolic reflector to effectively utilize luminous flux, thereby increasing illumination, avoiding dazzling, and greatly increasing efficiency of lighting fixtures. An outer casing of the street lamp is made of glass fiber materials, and the technique of heating a cavity of the street lamp in cold seasons is adopted, so that the street lamp is light and firm, is beautiful and durable, and has the advantages of heating and thermal insulation, thereby prolonging service life of electric appliances and light source systems. An electronic portion of the street lamp is supported by an internal steel framed structure, thereby reducing impact to the electronic portion from accidental hits.

Beneficial technical effects of the present utility model is:

1, the passive heat radiation technology is applied to T5 (or T3, T4, T6) three primary colours straight pipe type or U type fluorescent lamp, " heat pipe+aluminium matter fin slices radiator " high-power passive radiating mode, effectively take away T5 (or T3, T4, T6) light source is at a large amount of heats of lamp holder generation, increase the service life, solved T5 (or T3, T4, T6) three-color fluorescent lamp can not be used for an outdoor difficult problem, thereby make street lamp also can use T5 (or T3, T4, T6) this light high-quality, (the pupil lumen reaches about 190Plm/W energy-efficient " green light source ", nearly 4 of sodium vapor lamp times), every street lamp power consumption is reduced to 112W～144W, economizes on electricity more than 70% than conventional road lamp.

2, electric ballast applies to street lamp, and a large amount of uses of the electrical appliance of this capacitive on electrical network improve power grid quality thereby help the power factor (PF) decline that causes on the high side of compensation network perception electrical appliance.

3, the method that adopts 4～10 14W～18WT5 (or T3, T4, T6) three primary colours straight pipe type or U type fluorescent tube to be arranged side by side, and be adopted as the technology that each tubes is equipped with the parabolic shape reflector separately first, effectively utilize luminous flux, improve illumination, avoid dazzle, thereby Luminaire efficiency is increased substantially.

4, adopt glass fiber material to make the technology of street lamp shell and the technology that cold season, street lamp cavity heating resistor heated automatically, street lamp possesses that light weight is firm, attractive and durable, have the characteristics of heating and insulation winter thereby make, and has further prolonged electrical equipment and light-source system service life.

5, electronic section is supported by inner steel frame construction, reduces the impact of accidental impact to electronic section.
