Description
Technical field
The present invention relates to a kind of high light large power LED road lamp.
Background technology
The energy consumption of lighting field accounts for 20% of whole electric energy, and that common illuminating lamp only has 30% electric energy to be used for is luminous, and all the other have changed into heat energy and have distributed to the external world.The heat that LED produces during because of its work is less, and luminous efficiency is higher, is regarded as cold light source.The LED street lamp is made up of substrate, lens and the cooling system etc. of band LED, compares with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%.Since it is born,, more and more be subjected to the attention of countries in the world with its efficient low-consume, energy-conserving and environment-protective, long characteristics of life-span.China is used for the electric power of street lighting present every year near 2,500 hundred million degree, and wherein if can have 1/3 to adopt the LED street lighting, annual just can the economize on electricity about 80,000,000,000 degree is equivalent to the annual electricity generating capacity in power station, Three Gorges basically.The LED illuminating lamp has become people's main R﹠D direction.
As shown in Figure 1, single led 1 light that sends forms the taper light beam, and its brightness and range of exposures are all limited.As shown in Figure 2, be a kind of schematic diagram of existing typical LED street lamp, it comprises some LED 1 and plane substrate 2, and LED 1 is arranged on the plane substrate 2 in the mode of dot matrix, and its range of exposures is still little.The LED street lamp that also has a kind of U of having type cross section substrate 2 at present, but its range of exposures is subjected to the influence at substrate sidewall angle of inclination: and when the sidewall slope angle was big, its illuminating effect was very nearly the same with the LED street lamp that has the plane substrate; When the sidewall slope angle is less, then can occurs shining inhomogeneous light and dark phenomenon as shown in Figure 3, even under lamp, the blind area can occur as shown in Figure 4.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide that a kind of range of exposures is wide, illumination evenly, the strong high light large power LED road lamp of transition sense.
The technical solution adopted in the present invention is: the present invention includes the substrate that is provided with several LED, described substrate comprises planar portions and is positioned at the relative separately inclined-plane of two-stage at least of described planar portions both sides, several described LED are arranged on described planar portions and each the described inclined-plane, the light-emitting area of being made up of several described LED is concavity, described inclined-plane comprises two first order inclined-planes, inclined-plane, two second level, angle between two described first order inclined-planes is α, angle between the inclined-plane, two the described second level is β, 100 °≤α≤135 °, 80 °≤β≤110 °, the angle of divergence that is positioned at the described LED on the described planar portions is 60 °, the angle of divergence that is positioned at the described LED on the described first order inclined-plane is 60 °, and the angle of divergence that is positioned at the described LED on the inclined-plane, the described second level is 45 °.
Further, α=130 °, β=86 °.
