Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1, embodiment illustrated in fig. 2 in, this high heat dissipation, energy conservation LED street lamp comprises the lamppost 1 be made up of metal tube; The slideway extended along lamppost is shaped with in described lamppost 1; In described slideway, coupling has the metal block 2 drawn by stepper motor (widget, not shown); LED seat 3 is fixed with above described metal block 2, and the thermal component thermal conductive contact of described metal block 2 and LED seat 3, described thermal component is the metallic plate extended to below LED panel outside LED seat 3; Described LED seat 3 also comprises the LED lamp holder of the illumination that can produce straight up; The thermal component of described LED seat 3 is also provided with temperature sensor, described stepper motor draws described metal block 2 as follows: when the temperature of the thermal component of described LED seat 3 is greater than setting value, makes described metal block 2 along a segment distance sliding on described slideway; When described metal block 2 has slid into the top of described slideway, then metal block has been made to slide to slideway bottom 2 times; The upper end of described lamppost 1 is provided with arc reflection plate 4, and the illumination reflection that described LED seat 3 projects by described arc reflection plate 4 is straight up to road surface, and its light path as shown in phantom in Figure 1.
Above-mentioned high heat dissipation, energy conservation LED street lamp, transparent watertight cover plate 5 has also been sealed in the upper end of described lamppost 1, falls into lamppost with rainwater-proof; Further, this waterproof cover 5, in skewed, is beneficial to rainwater slide.Described stepper motor is drawn described metal block 2 by the pull rope 6 of the madial wall near described lamppost 1.
Above-mentioned high heat dissipation, energy conservation LED street lamp operationally, when the temperature of the thermal component of LED seat 2 is elevated to setting value (that is now the heat of LED seat 2 near zone starts to pile up); Metal block 2 rises a segment distance together with LED seat 3, thus leave the heat build-up district on lamppost 1 surface, contact with the cold-zone on lamppost surface, the surperficial cold-zone of the thermal component of LED seat 3, metal block 2, lamppost 1 forms again an excellent quick heat radiating regional area; That is the thermal component of LED seat 3 always runs to the regional area of relative low temperature, thus ensures good radiating effect; In addition, move up and down in process at LED seat 3, because the irradiating angle of LED seat 3 pairs of reflecting plates 4 is constant, namely vertically irradiate all the time, therefore do not affect the reverberation photograph of reflecting plate 4 road pavement, this street lamp remains stable illuminating effect.
