Description
Technical field
The utility model relates to a kind of street lamp, particularly a kind of street lamp of making light source with cold-cathode fluorescence lamp, be used for illuminations such as road lighting, tunnel illumination, billboard lighting, bridge, mansion, market, square and view, alternative existing high-pressure mercury lamp, high-pressure sodium lamp, electrodeless lamp, Metal halogen lamp, high-power hot cathode electricity-saving lamp etc.
Background technology
The high light flux light source that prior art is used for illuminations such as street lamp mainly contains low-pressure sodium lamp, high-pressure mercury lamp, high-pressure sodium lamp, electrodeless lamp, Metal halogen lamp etc.
The fluorescent tube photopic vision luminous efficiency of low-pressure sodium lamp is up to 180lm/W, but its colour rendering index is very low, now less use.
High-pressure mercury lamp has higher luminous efficiency, its fluorescent tube photopic vision luminous efficiency is 90-120lm/W, life-span can reach 25000 hours, it is the main force of present street lamp, Tunnel Lamp, this high-pressure mercury lamp of street lamp of China about 80%, but the colour rendering index of high-pressure mercury lamp is low, about 20-25 only, colour temperature is 2000-2400K, its main spectrum is positioned at gold-tinted, photopic vision/noctovision ratio is about 0.6, the only about 54-56lm/W of the scotopic luminous efficiency of fluorescent tube, and its object resolution is low, and promptly the object visibility is low, and is unfavorable to safety; Than the white light high-pressure mercury lamp of high color rendering index (CRI), luminous efficiency 37-48lm/W only.
The about 50lm/W of high-pressure sodium lamp luminous efficiency, colour rendering index is about 45, and the life-span is short, less at present use.
