Abstract
An over-long spacing high-power LED street lamp mainly comprises LED light sources, light reflectors, a lamp shade and a heat dissipation base plate, and is characterized in that: each LED light source consists of a singly packaged LED element and an LED array with a plurality of packaged LEDs; moreover, the LED light sources are arranged inside a plurality of sets of light reflectors with different light reflecting curved surfaces; therefore, a plurality of sets of LED modules are formed and fixed on the heat dissipation base plate according to the illuminating light path of the LED street lamp. The utility model has the advantages that: the spatial arrangement angle of the light reflectors and the LED modules can be selected to reshape the emergent light beam of the LED modules; meanwhile, the utility model increases the utilization rate and evenness of the illuminating ray of the street lamp, thereby realizing over-long spacing even illumination; moreover, the utility model, which reduces the number of street lamps within unit road length, reduces electricity utilization and saves installation cost.
Description
Technical field
The utility model 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 purpose of this utility model is at the defective that exists in the prior art, and a kind of ultralong distance and high power LED street lamp is provided.The utility model 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 described in the utility model is meant along road direction two lamp spacings more than 50 meters.
The utility model has the advantages that by suitable selection reflector and led module space arrangement angle, the led module outgoing beam is carried out shaping, most light are distributed in the required road lighting zone, improve 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.
