Abstract

The invention relates to a super energy-saving LED street lamp, which comprises a lamp post, a lighting instrument, and a light source. The invention adopts multipoint, layering and accurate illumination techniques. The light source on the lamp post is a plurality of small-angle LEDs that are equipped in dispersed and layered manner, the illumination angle of each LED is accurately positioned, each LED illuminates a piece of load surface, and the plurality of LEDs illuminate a length of road surface. The used LEDs are small-angle LEDs with power of 1-3 Watt and light emission angle of 15-65 DEG, and each LED is equipped with a heat radiator. The lighting instrument on the lamp post is downwardly equipped in two or more layers from the top of the lamp post. The invention is indeed a super energy-saving LED street lamp with the advantages of low electricity consumption, stable performance, long service life, no pollution, simple application, simple structure, easy arrangement, low investment, large application range, and good extension prospect. Especially, the energy-saving effect is remarkably, and the power consumption is only 1/8 of the light source of the existing street lamp.

Description

Super energy-saving LED road lamp

Technical field

The present invention relates to electrical lighting, particularly, is a kind of other illuminating street lamp of road that places.

Background technology

The illuminating street lamp of urban road is important communal facility.The road of GB regulation different stage has corresponding lighting standard.In order to illuminate the road surface effectively at night, just require street lamp that enough power and brightness are arranged.Along with the grade of road and the raising of width, more and more higher to the power and the brightness requirement of road-light light-source.Therefore, people are making great efforts to improve light source always, improve its brightness, and light source power is also increasing thereupon.At present, road-light light-source has progressively been developed into various new type light sources such as halogen tungsten lamp, high-pressure sodium lamp, high-pressure mercury lamp, metal halide lamp by incandescent lamp.Though these new type electro source brightness height, power is also big, and power consumption increases greatly, and the light beam of existing light source mostly is 360 ° of spherical divergences formation floodlighting greatly.Though what have is provided with reflection shield, its light beam is through pointing to the road surface that need illuminate after the reflected refraction again, and the light efficiency loss is very big, the requirement of the environmental protection and energy saving that are far from suitable.Therefore, want energy savings significantly, just must thoroughly change street lamp illumination system.In the recent period, LED more and more is subjected to people's attention as a kind of new light sources.The LED light emitting diode both had been different from incandescent lamp as a kind of electroluminescent light source, and the contour heat radiation light source of halogen tungsten lamp also is different from glow discharge spot lamps such as fluorescent lamp, high-pressure mercury lamp, and it is an electroluminescent light source.Its basic functional principle is to utilize the solid semiconductor chip as luminescent material, when two ends add voltage, carrier in the semiconductor takes place compoundly to cause photo emissions and produce light, the only non-radiative light that is sent, photochromic pure, light beam are concentrated, high, the good temp characteristic of colour rendering index, have advantages such as electric quantity consumption is low, stable performance, the life-span is long, pollution-free, use is simple.Now existing LED more than 1 watt, luminous flux reaches every watt of 80Lm, the beam divergence angle of launching is generally 90 °-140 °, its cost performance entered in the road lighting field can large-scale practical application stage.But the single power of LED is limited at present, and mature and stable product can only be accomplished several watts, uses it for road lighting, need to explore new light illumination mode, science design lamp post structure, changing floodlighting is directional lighting, with the speciality of performance LED, pursue best energy-saving illumination effect.

Summary of the invention

Super energy-saving LED road lamp of the present invention is made up of lamp stand, light fixture and light source, has adopted multiple spot, layering, accurate positioning irradiation technology.Light source on its lamp stand is the low-angle LED that a plurality of dispersions, layering are provided with, and each LED irradiating angle is precisely located, and shines a block road separately, and illuminates the stretch face in flakes.Used LED is power 1-3 watt, and the beam emissions angle is 15 °-65 ° low-angle LED, and each LED all is furnished with radiator.Light fixture on the lamp stand is two-layer above multilayer, the past lower leaf setting from the lamp stand top.Through experiment, on 6 meters high lamp stands, down be divided into 4 layers from lamp stand top the LED that 1 watt of 32 power, the angle of departure are respectively 15 ° and 30 ° is installed, every layer of 8 LED, every LED are accurate location separately, illuminate a block road, and illuminate one section 30 * 12 meters road surface in flakes, through measuring, center, road surface illumination is higher than 35Lx, the uniformity＞0.4 meets GB trunk roads lighting criteria fully.And used light source power consumption only is 32 watts.As adopt high-pressure mercury lamp, luminous power then to need 250 watts.Claim the present invention for energy-saving to be not, if extensively adopt the present invention, its energy-saving effect is difficult to metering.The present invention is simple in structure, easily installs, and small investment, applied range has promotion prospect.

The specific embodiment

As shown in the figure, on 6 meters high lamp stands 1, from lamp stand 1 top 4 layers of light fixture 2 are set down, every layer of light fixture has every LED irradiating angle of 8 LED3 precisely to locate, and its light beam illuminates a block road, and illuminates 30 meters long, 12 meters wide stretch face in flakes.Improve the uniformity as needs, can consider to set up LED at high level, many LED point to same block road.
