Abstract
The present invention relates to an ultra-long-spacing large-power luminescent diode LED street lamp, which mainly comprises an LED light source, a reflector, a lamp hood and a heat radiation substrate, and is characterized in that the LED light source consists of a single encapsulated LED element or a plurality of encapsulated LED arrays; the LED light source is arranged into multiple groups of reflector with different reflection curved surfaces, to form multiple groups of LED modules; the modules are distributed and fixed on the heat radiation substrate according to the illuminating light circuit of the LED street lamp. The LED street lamp of the present invention has the advantages that the shining light beam of the LED module is shaped by selecting the reflector and the space arrangement angle of the LED modules, thereby improving the illuminating light utilization rate and evenness of the street lamp, realizing the uniform illumination in an ultra long distance, reducing the quantity of the street lamp within a specific road length, saving the electric power, and saving the installation expense.
Description
Technical field
The present invention relates to a kind of great power LED lamp, particularly a kind of ultralong distance and high power LED street lamp.
Background technology
Along with expanding economy and urbanization construction constantly enlarge, traffic route constantly increases, the electric energy that street lighting consumed also significantly improves thereupon, along with energy today in short supply day by day, how to make street lighting not only guarantee under the situation of illumination but also energy savings is the problem that people study.And present employed conventional road lamp, owing to be subjected to the restriction of lamp luminescence characteristic and the reflective characteristic of lampshade, be difficult in and guarantee that the higher long spacing that realizes when going out light utilization efficiency evenly throws light on, so the brightness and the uniformity in order to guarantee illuminated road surface, the installing space of conventional road lamp designs nearerly, be generally 20 meters to 40 meters, this just in the unit's of making link length the street lamp quantity of low light utilization efficiency more, power consumption is bigger.
Light emitting diode (LED) light source is a kind of electroluminescent solid cold light source that utilizes, advantage such as have the luminous efficiency height, volume is little, in light weight, power consumption is few, long service life, colour rendering are good, shatter-proof, shock-resistant, be replace incandescent lamp, tengsten lamp and fluorescent lamp the 4th generation lighting source.The energy-saving street lamp of high-brightness LED has become a kind of trend as a kind of novel city illumination, but the LED street lamp that is provided in the market is because a variety of causes, have following problem: 1, illumination distances is short, is generally 20 meters to 35 meters, and the cloth lamp is more in the unit link length; 2, light utilization efficiency is lower, and its distribution curve flux is symmetrically distributed in vertical 180 ° of scopes of road surface direction, and making has many light not drop on the required illuminating road road surface, and the road surface light utilization efficiency is lower; 3, the road lighting uniformity is low, forms hot spot on road, causes driver's driving fatigue easily.Because more than, make present LED street lamp power consumption in the unit link length still bigger, illuminating effect is not good, does not embody the energy-efficient characteristics of led light source.
Summary of the invention
The objective of the invention is provides a kind of ultralong distance and high power LED street lamp at the defective that exists in the prior art.The present invention mainly comprises: light emitting diode (LED) light source, reflector, lampshade and heat-radiating substrate, it is characterized in that described led light source is made up of single encapsulated LED element or many encapsulated LED arrays, led light source is sub-divided in the reflector of the different reflective surfaces of array, form the array led module, these modules are fixed on the heat-radiating substrate by the light path distribution of LED street lighting.Ultralong distance of the present invention is meant along road direction two lamp spacings more than 50 meters.
Advantage of the present invention is by suitable selection reflector and led module space arrangement angle, and the led module outgoing beam is carried out shaping, and most light are distributed in the required road lighting zone, improves the street lighting light utilization efficiency and the uniformity; The LED volume is little, the characteristics of space flexible distributed but utilize, select different LED, reflector and arrangement combination of angles, realize that ultralong distance evenly throws light on, thereby enlarge the range of exposures of street lamp, increase the spacing of adjacent street lamp, reduce the street lamp quantity in the unit link length, mounting cost is saved in the electricity consumption that saves lighting.
