Abstract
The utility model discloses a concave LED streetlamp, which comprises a casing, a mirror plane, substrates and a bulb. The mirror plane is fixed to the upper end of the casing, the two substrates are respectively disposed on the upper portion and the lower portion in the casing, the bulb is fixed to the middle of the upper surface of the substrate on the upper portion of the casing, a battery box is disposed on the lower surface of the substrate on the upper portion of the casing, a stretching aluminum radiator is disposed on the upper surface of the substrate on the lower portion of the casing, the mirror plane is sunk downwards, and a lens is disposed on the lower surface of the mirror plane. The concave LED streetlamp avoids glaring, and is fine in radiating effect and long in service life.
Description
Technical field
The utility model relates to a kind of street lamp, particularly a kind of matrix LED street lamp.
Background technology
In the society a lot of LED street lamp kinds are arranged at present, big in order to reach irradiated area, the minute surface of street lamp cap all is a convex generally, and the negative effect that brings is exactly dazzle.A lot of LED street lamp kinds all be with integrated LED chip as light source, radiating effect is not fine, heat is too concentrated can to influence light source service life.
Summary of the invention
The purpose of this utility model just is to provide a kind of dazzle that do not have, good heat dissipation effect, the matrix LED street lamp of long service life.
To achieve these goals, the technical solution adopted in the utility model is such: matrix LED street lamp of the present utility model, comprise housing, minute surface, substrate and lamp pearl, minute surface is fixed on the housing upper end, and described substrate is two, and be separately positioned on top and the bottom in the housing, described lamp pearl is fixed on the upper surface middle part of the substrate on top, and its lower surface is provided with power pack, and the upper surface of the substrate of bottom is provided with the stretching aluminium radiator, described minute surface is to lower recess, and its lower surface is provided with an optical lens.
As preferably, described substrate is made of aluminum.
As preferably, the mid portion of described optical lens is 60 degree lens, is followed successively by 45 degree lens, 30 degree lens, 15 degree lens, 5 degree lens from the inside to the outside.
As preferably, described minute surface adopts force-bearing plate.
Compared with prior art, advantage of the present utility model is: irradiated area is big, and power is low, power saving under the equal brightness, and material benefit is practical, and maintenance cost is low.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, matrix LED street lamp of the present utility model, comprise housing 1, minute surface 2, substrate 3 and lamp pearl 4, minute surface 2 is fixed on housing 1 upper end, described substrate 3 is two, and be separately positioned on top and the bottom in the housing 1, described substrate 3 is made of aluminum, and described lamp pearl 4 is fixed on the upper surface middle part of the substrate 3 on top, its lower surface is provided with power pack 6, the upper surface of the substrate 3 of bottom is provided with stretching aluminium radiator 7, good heat dissipation effect, and described minute surface 2 is to lower recess, promptly solve heat radiation and solved dazzle again, irradiated area also increases simultaneously, and the lower surface of minute surface 2 is provided with an optical lens 5, and the mid portion of described optical lens 5 is 60 degree lens, be followed successively by 45 degree lens from the inside to the outside, 30 degree lens, 15 degree lens, 5 degree lens, after arranging lens like this, the brightness on illuminated road surface is even, and irradiated area is very big; Described minute surface 2 adopts force-bearing plate.
