Description
Technical field
The utility model belongs to field of illuminating device, relates to a kind of LED light fixture, relates in particular to a kind of luminous intensity distribution type LED street lamp.
Background technology
LED street lamp (Light Emitting Diode, Light-Emitting Diode) is a semi-conductor lighting lamp.It is the efficient solid state light emitter that the faint electric energy of usefulness that a kind of based semiconductor PN junction forms just can be luminous; Under certain forward bias voltage and injection electric current; The electronics that injects hole and the injection N district in P district is diffusing to active area after radiation recombination and send photon is converted into luminous energy with electric energy.It is a kind of solid-state cold light source, has characteristics such as environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, and therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is big has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is present institute urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection has a crucial meaning to city illumination is energy-conservation.
Road lighting and people's productive life are closely related; Quickening along with Urbanization in China; Advantages such as the LED street lamp is luminous with orientation, power consumption is low, drive characteristic good, response speed is fast, shock resistance is high, long service life, environmental protection enter into gradually people the visual field, become the energy-conserving light source of new generation that at present has most alternative conventional light source advantage in the world; Therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.
The LED lighting engineering reaches its maturity, and the high-power LED light source effect has reached 100lm/W above (lm/W is the unit of source efficiency), and this makes the city street lamp lighting energy saving be transformed into possibility.LED street lamp, particularly high-power LED street lamp are just with the traditional street lamp market of swift and violent velocity shock.
High-power LED street lamp as the term suggests be power greater than more than 30 watts, adopt the street lamp of New LED semiconductor light sources.The standard of LED street lamp generally is the average illumination 0.48 of the road illumination uniformity (uniformity of road surfaceilluminance) at present.Hot spot ratio 1:2 meets road illumination.(actual 1/2 center spot reaches 25LUX, and 1/4 central light strength reaches 15LUX, 16 meters far away minimum light intensity 4LUX, the about 6LUX of overlapping light intensity.
At present, make the main direction that street lamp has become road lamp energy-saving, but there is defective in the street lamp that LED makes on luminous intensity distribution with led light source.The LED street lamp generally has only the LED lamp plate of one flat plate structure, and as the restriction of road lighting owing to beam angle, obviously illumination is not enough in the area of the vertical decentre of road more than ten meters.The angle of light source center largest light intensity direction and its 1/2 light intensity direction is a beam angle.Beam angle has determined the size and the light intensity of face to be illuminated hot spot, and beam angle is big more, and central light strength is more little, and hot spot is big more; Otherwise then hot spot is big, and light intensity is little.In order to remedy this defective, have only the LED of increasing lamp power, the result is the too high waste of center illumination, and illumination increase in edge is limited, uniformity of illuminance is poor.Another kind method is to install the lens light modulation additional, because the light transmittance of lens descends the utilization rate of light, has reduced Luminaire efficiency, makes that light is more dazzling dazzles the eyes.
