Abstract
An LED optical lens light-distribution street lamp comprises a lampshade and a light source module located in the lampshade, wherein the light source module comprises a circuit substrate, a light source array consisting of multiple LED light sources is installed on the front side of the circuit substrate in a pasting mode, the back side of the circuit substrate is pasted onto a heat-conductive aluminum substrate with through holes, the heat-conductive aluminum substrate is arranged on a radiator with cooling fins, a cap matched with the circuit substrate is arranged and provided with through holes corresponding to the LED light sources, planoconvex lenses are installed in the through holes, and planes of the planoconvex lenses face the LED light sources. The LED optical lens light-distribution street lamp utilizes the planoconvex lenses to perform secondary light distribution and fully utilizes light rays and the heat-conductive aluminum substrate to conduct heat to the radiator, the heat-conductive speed is accelerated, and the heat radiating performance is improved.
Description
Technical field
The utility model belongs to LED street lamp technical field, particularly a kind of LED optical lens road lamp.
Background technology
LED street lamp brightness and colourity aspect all have greater advantages than conventional road lamp, and its energy consumption is lower in addition, have therefore obtained large-scale application.But the same with all LED illumination application, there is the problem of heat radiation and lighting in LED street lamp.Some LED street lamps adopt fan cooling, but fan itself will consume energy, and does not meet Trend of Energy Saving.Aspect lighting, traditional adopting surface mounted LED is luminous comparatively to be dispersed, and has wasted a part of light.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of LED optical lens road lamp, can either carry out secondary light-distribution, converges light, has possessed again good heat dispersion.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of LED optical lens road lamp, comprise lampshade and the light source module that is positioned at lampshade, described light source module comprises circuit substrate 3, in circuit substrate 3 fronts, mount the array of source that a plurality of LED light sources 4 form, circuit substrate 3 back sides are adhered to the heat conduction aluminum substrate 2 with open-work, heat conduction aluminum substrate 2 is arranged on the radiator 1 with radiating fin, mate with described circuit substrate 3 and be provided with block 5, on block 5, corresponding to each LED light source 4, have through hole, planoconvex spotlight 6 is installed in through hole, and the plane of planoconvex spotlight 6 is towards LED light source 4.
Described lampshade is cube, and lampshade top is screen, and bottom is the heat sink with louvre.
Compared with prior art, the utility model utilizes planoconvex spotlight to carry out secondary light-distribution, takes full advantage of light, utilizes heat conduction aluminum substrate to conduct heat to radiator, has accelerated heat-transfer rate, has improved heat dispersion.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, describe embodiment of the present utility model in detail.
A kind of LED optical lens road lamp, comprise lampshade and the light source module that is positioned at lampshade, as shown in Figure 1, described light source module comprises circuit substrate 3, in circuit substrate 3 fronts, mount the array of source that a plurality of LED light sources 4 form, circuit substrate 3 back sides are adhered to the heat conduction aluminum substrate 2 with open-work, heat conduction aluminum substrate 2 is arranged on the radiator 1 with radiating fin, mate with described circuit substrate 3 and be provided with block 5, on block 5, corresponding to each LED light source 4, have through hole, planoconvex spotlight 6 is installed in through hole, and the plane of planoconvex spotlight 6 is towards LED light source 4.
Described lampshade is cube, and lampshade top is screen, and bottom is the heat sink with louvre, and side also can arrange some open-works.
Owing to having adopted said structure, the utility model is aspect heat radiation, because circuit substrate 3 belows add heat conduction aluminum substrate 2, therefore heat-transfer rate is accelerated, heat can be conducted to radiator 1, the open-work of lampshade both sides and can add strong convection with the heat sink of louvre, accelerates heat radiation.And the planoconvex spotlight 6 of block on 5 can guarantee that the light of LED light source 4 is fully converged, in block 5, also can further fill transparent heat sink material and strengthen heat radiation.
