Description
Technical field
The utility model relates to a kind of LED street lamp, particularly a kind of LED street lamp with the synthetic warm white light source of yellow, blue two kinds of color LED.
Background technology
Along with the develop rapidly of semiconductor technology, the trend of various traditional lighting light source products has appearred tentatively substituting in LED lighting engineering at present.LED as the lighting source of a new generation have height directionality, energy-saving and environmental protection, anti-flicker, color is various, regulation and control are convenient, reliability is high and the life-span such as grows at advantage significantly, it is the most competitive green light source product of 21st century, countries and regions such as America and Japan Korea Spro and Europe have all been listed it in the state key development plan, research and develop targetedly.Because LED is a spot light, lighting angle is convenient to control, be used more effectively so utilize the light source at specific luminous angle to do the light that local illumination can make light source send, can reach the local lighting effect that meets the demands with smaller power, thereby realize energy-conservation.Generally speaking, the LED street lamp all adopts white light, but the attenuation ratio of white light LEDs is bigger, also have its caloric value of great power LED to be much higher than common LED, so the light source that adopts the synthetic warm white of bright orange, the blue two kinds of colors of small-power superelevation to make the LED street lamp can effectively improve problems such as brightness, decay, heat radiation.
Summary of the invention
The purpose of this utility model is to solve the high-power blue light wafer of available technology adopting excitated fluorescent powder to make white light LEDs and make the problem that the existing decay of LED street lamp is big, luminance is low again, and a kind of LED street lamp that adopts high brightness Huang, blue two kinds of LED to be mixed into warm white is provided.A kind of LED street lamp that adopts high brightness Huang, blue two kinds of LED to be mixed into warm white of the utility model design, comprise lamp housing, heat carrier, radiator, lampshade, constant-current source, it is characterized in that: the LED lamp plate is arranged in lamp housing, be welded with Huang, blue two kinds of LED on the LED lamp plate, yellow, blue two kinds of LED are driven by constant-current source after the connection in series-parallel separately.Huang on the LED lamp plate, blue two kinds of LED evenly distribute.The yellow led wavelength is 585nm-610nm, and the blue led wavelength is 450nm-480nm.The brightness ratio of Huang on the LED lamp plate, blue two kinds of LED is 5～7: 0.5～1.The irradiates light shape of yellow, blue two kinds of LED is oval.The utility model has the advantages that: adopt the light source of the synthetic warm white of bright orange, the blue two kinds of color LED of small-power superelevation as street lamp, can effectively control the distribution of light by the method for angle of control luminous tube, the light that luminous tube is sent becomes a strip light belt and sprawls along the road surface direction, facts have proved, the power of about 90 watts of semiconductor road lamps of Zhi Zuoing just can be above 250 watts of illuminating effects of receiving the lamp road pavement like this, and energy-saving effect is remarkable.Its life-span is long, and is lower than the street lamp cost of other LED, photochromic very photochromic near street lamp used on the present road.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
Comprise lamp housing 1, heat carrier 2, radiator 3, lampshade 4, constant-current source 5 among the figure, it is characterized in that: LED lamp plate 6 is arranged in lamp housing 1, be welded with Huang, blue two kinds of LED7 on LED lamp plate 6, yellow, blue two kinds of LED7 are driven by constant-current source 5 after the connection in series-parallel separately.Huang on the LED lamp plate 6, blue two kinds of LED7 evenly distribute.Yellow led 7 wavelength are 585nm-610nm, and blue led 7 wavelength are 450nm-480nm.The brightness ratio of Huang on the LED lamp plate 6, blue two kinds of LED7 is 5～7: 0.5～1.The irradiates light shape of yellow, blue two kinds of LED7 is oval.
During specific implementation, the LED7 of bright orange several small-power superelevation, blue two kinds of colors is welded on the LED lamp plate 6, and the LED7 of yellow, blue two kinds of colors connection in series-parallel separately is combined into illuminator.Wherein yellow led 7 wavelength are 585nm-610nm, and blue led 7 wavelength are 450nm-480nm.When reality is mixed colours, the LED7 of yellow, blue two kinds of colors according to certain 5～7 (Huangs): the brightness ratio scope of 0.5～1 (indigo plant) is regulated, and makes it be shown as warm white.As adopting yellow 6: blue 1 brightness ratio is carried out proportioning.It is lower than the cost of white light LEDs, and its light-emitting area of the LED7 that uses is ellipse, and luminous efficiency height, irradiated area are oval, have well satisfied the requirement of street lamp.
