Description
Technical field
The invention belongs to the lighting apparatus field, relate to a kind of LED road lamp device.
Background technology
Road lighting is one of important component part of urban infrastructure, and it plays an important role for traffic safety and social security, can also beautify the appearance of the city simultaneously, decorate environment, makes each tool style of each city.Recently, country strengthens day by day to the attention of environmental protection, leaders at different levels from President to the district, and the focus of work is all to the transfer of curbing environmental pollution, and " Green GDP " also become the hot issue in the daily life.And road lighting is as an important component part of infrastructure, the inevitable target that becomes energy-saving and emission-reduction.At present, use more fluorescent lamp, high-pressure sodium lamp and high-pressure mercury lamp etc., though luminescent properties is better, but there is problems such as not growing, cause easily mercury pollution service life, therefore, along with the promulgation of " Eleventh Five-Year Plan City Green illuminating engineering planning outline ", the environmental protection lighting light fixture more will become a hot subject.
Summary of the invention
The purpose of this invention is to provide all good road lamp devices of a kind of environmental-protecting performance and luminescent properties.
Along with the continuous progress of LED (light emitting diode) manufacturing technology, its light efficiency is constantly soaring, and the light efficiency of large power white light LED has reached 100lm/w up to now, and stable product light efficiency also has 80lm/w.This light efficiency value shows the potentiality that LED is applied to the general illumination on the practical significance.Add that the LED life-span is long, shock resistance good, the little approximate spot light of volume, drive all characteristics such as simple, LED has the competitiveness that outclass high-pressure mercury lamp in the road lighting field undoubtedly.

The core advantage that support LED becomes optimum road lighting source has four:
(1), by research to the LED luminescence mechanism, the potential light efficiency that can extrapolate LED can reach 350lm/w. and consider technologic limitation, actual LED light efficiency is expected to reach 200lm/w, single from light-source angle, LED is undoubtedly the highest light source of following light efficiency, in other words, is exactly the most energy-conservation light source.
(2) compare with conventional light source, the LED volume is little, in many application scenarios even it can be handled as spot light, this brings very big facility just for the optical design of light fixture. and simultaneously, the light source that occurs in the use large scale conventional light source light fixture blocks with absorption and has not also existed.
(3) LED only emits beam to half space, this means and do not add any type of reflector, the light that light source sends is whole directive area of illumination directions also, like this, the calculating of the Luminaire efficiency of LED light fixture is just different with the conventional light source light fixture, no longer needs to have given a discount again. and these characteristics have determined the LED light fixture can accomplish the utilance more than 90% fully.
(4) under the brightness of illumination environment (road illumination 1-2lx) of road at night, the mediate state of vision of human eye. at this moment, the white light that equal brightness white light LEDs sends is compared with the gold-tinted that high-pressure mercury lamp sends and is obtained higher human eye vision excitation. and promptly: the angle with the people is observed, the lighting environment of white light is brighter than gold-tinted environment. and the theory of this mesopic vision has just supported white light LEDs to replace the application of gold-tinted sodium vapor lamp. under the prerequisite that guarantees identical road lighting level, the brightness of white light will be lower than gold-tinted, and this has added a counterweight again for LED on the advantage of lighting energy saving.
The invention provides a kind of LED road lamp device that forms rectangular light spot.In this device, led module 1-50 of the band Optical devices is one group, is installed in the light fixture in groups; Optical devices are made up of aspheric surface central authorities collimation lens, parabola reflector and aspherical microlens array; Led light source is installed in the reflector bottom, and the aspherical microlens array vertical optical axis is placed, and adjusts aspheric surface central authorities' collimation lens and the position of aspherical microlens array in the parabola reflector and the elevation angle of LED, makes the parallel outgoing of light of LED.
Among the present invention, aspheric surface central authorities collimation lens and the aspherical microlens array position and the elevation angle of LED in the parabola reflector can be mutually adjusted according to the size of reflector, street lamp height etc., so that the parallel outgoing of the light of LED, form the uniform rectangle speck of illumination at the target illumination face, satisfy the road illumination that national road illumination standards requires.
Among the present invention, led module is installed in lamp base in groups.
Among the present invention, led module 1-10 is one group.
Among the present invention, aspherical microlens array is a 2-100 aspherical microlens.
The invention provides a kind of secondary optics project organization based on large-power light-emitting diodes (LED).Its main feature has:
(1) the corresponding independent optical system of every LEDs, concrete optical system is made up of colimated light system and divergent lens two parts.The light that is sent by LED is gone out with certain angular dispersed through the aspheric surface divergent lens through the parallel light emergence of colimated light system furnishing parallel system optical axis again.
