Description
Technical field
The utility model relates to the road lighting technical field, relates in particular to the luminous intensity distribution utilization of road lighting.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and 360 ° of high-pressure mercury lamps are luminous, and light loss is large, and the shortcoming that light efficiency is low causes the huge wave of the energy; Life cycle is short, and maintenance cost is high; Color developing is low, and the vision reducing power of object is poor, easily causes driver's visual fatigue; The light decay poor performance can descend more than 30% in 1 year.Therefore develop high light efficiency, energy-conservation, life cycle is long, colour rendering index is high, the novel street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.
Low-pressure sodium lamp has similar principle as a kind of gas-discharge lamp with the high-pressure mercury lamp principle of luminosity, adopt the arc discharge luminous tube of a double end by external connected electronic ballast powered operation, its characteristics are that what send is monochromatic gold-tinted, emission wavelength is 589.0nm and 589.6nm, these two chromatograms are near the sensitiveest 555.0nm wavelength of human eye, do not produce aberration in human eye, therefore look and see that resolution ratio is high, good contrast, so the light penetration capacity is strong, " mist transmitting " that is embodied in it is that other light source is all incomparable; The wavelength of the resoance radiation that low-pressure sodium lamp produces and look the close cause of peak value of seeing sensitivity curve, so the illumination utilization ratio is high, luminous efficiency can reach 200lm/W, photoelectric transformation efficiency can reach more than 80%; That low-pressure sodium lamp also has is dazzle-free, life-span long (can reach 20,000 hours), light decay, little (light decay only had 5% in 8000 hours, also can reach the 80%-85% of initial luminous flux when dying of old age) etc. characteristics also be widely used in road lighting, the application places of low-pressure sodium lamp is also in continuous expansion, the photopic vision light efficiency is very high, cause the colour rendering extreme difference but its spectrum is narrow, the characteristics of colour rendering index Ra≤20 can't make its sustainable development again.
The LED luminescent device is as a kind of solid-state cold light source, adopt the work of AC-DC power drives low-voltage power supply, the security and the drive characteristic that have guaranteed its charged work are good, had again that semiconductor material is environment friendly and pollution-free, little power consumption, life-span long (20000-50000 hour), light decay little (1 year less than 3%) colour rendering index 〉=75, the luminous one-way of LED do not have diffusion of light to guarantee source efficiency, unique secondary optical design has improved its light efficiency, the light efficiency theory can reach the characteristics such as 250lm/W, will become the optimal selection of roadway illumination and energy saving transformation.Market also has certain limitation but it is widely used in road lighting.
Summary of the invention
The technical problem that the utility model solves is by present low-pressure sodium lamp LPS light source and LED street lamp being carried out the mixed spectrum combination of light source, utilize low-pressure sodium lamp on D spectrum high light efficiency and penetrability combine with the advantages such as high-color rendering of LED make this street lamp have high light efficiency, high-color rendering, life-span long, can adapt to various natural environments, novel street lamp that cost is low.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of LPS-LED mixed light street lamp, it is characterized in that: comprise LPS light source and LED light source module body, described LPS light source is arranged in the lamp body reflection shield, and the LED light source module body is embedded on the lamp body shell with modular mode.Wherein LPS light source body is by low pressure high-frequency model output voltage power supply in power supply driver, and the LED light source module body is carried out power voltage supply by DC output module in power supply driver.
At first the technical program sends wavelength by low-pressure sodium lamp LPS is the monochromatic gold-tinted that 589.0nm and 589.6nm have the very strong narrowband wavelength of penetration performance, by the lamp body reflection shield, monochromatic gold-tinted is projected the road surface of throwing light on, then the white light with high-color rendering that sends by the LED light source module body at two ends, the monochromatic gold-tinted that the white light that the LED light source module of the certain PROCESS FOR TREATMENT of process is sent and low-pressure sodium lamp LPS light source body send carry out effective mixed light to be processed.
Further the LED light source module body is respectively installed a modularized light source before and after centered by LPS light source body, and LED luminescent device scioptics carry out the sodium yellow that secondary optical design and LPS light source body send and carry out photochromic overlapping mixed light.The light source that institute's mixed light sends have color rendition index high, look and see that resolution ratio is strong, the object good contrast.The light efficiency of whole light fixture is high, photoelectric transformation efficiency is high, life time is long, the market difficult problem that maintenance cost is low, can effectively make up LED street lamp high cost.
