Accompanying drawing explanation
Fig. 1 is the view of an embodiment under solar irradiation of this solar street light.
Fig. 2 is the view of Fig. 1 embodiment when night.
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 solar street light comprises the hollow lamp stand 1 be made up of metal tube; The outer wall of described lamp stand 1 is enclosed with a vacuum heat collection pipe 2 extended along lamp stand; And described lamp stand 1 inner sealing has heat-storage agent; The lower end of described lamp stand 1 is fixed on thermal insulating seat (not shown), and described thermal insulating seat and ground fix, and make lamp stand 1 and ground insulation.
The upper end of described lamp stand 1 is provided with adiabatic end seat 3, offers the slideway 30 running through adiabatic end seat along lamp stand axis in described thermal insulation end seat 3; A coupling heat conduction slide bar 4 in described slideway 30, the upper end of described heat conduction slide bar 4 is fixed with a thermoluminescence body 5.
Described street lamp also comprises an elevating mechanism that described heat conduction slide bar about 4 can be made to stretch, described elevating mechanism comprises the heat conduction telescoping tube 6 that is parallel to the surperficial extinction of heat conduction slide bar 4, the lower end of described telescoping tube 6 is fixed on described thermal insulation end seat 3, and upper end is fixed on the upper end of described heat conduction slide bar 4; When described telescoping tube 6 is elongated to the limit, raised the lower end of described heat conduction slide bar 4 in the slideway 30 of described thermal insulation end seat, state now as shown in Figure 1; And described telescoping tube 6 is when being retracted to the limit, the lower end of described heat conduction slide bar 4 is pulled down to described lamp stand 1 inner, state now as shown in Figure 2; Mercury is sealed with in described telescoping tube 6.In order to make the surperficial extinction of described telescoping tube 6, only black need be made in its surface; Because telescoping tube 6 inner sealing has mercury, under illumination condition, mercury expanded by heating in telescoping tube 6, longitudinally extends telescoping tube, thus raises described heat conduction slide bar 4; And under non-illumination condition, mercury cooling is shunk in telescoping tube 6, described telescoping tube 6 is longitudinally shortened, thus drop-down described heat conduction slide bar 4.This elevating mechanism, completely without the need to electric-control system, makes whole street lamp abandon power line completely; And structure is simple, and cost is very low, also not fragile.
In the present embodiment, above described thermal insulation end seat 3, also fix one piece of opening up parabolic panel 7; The upper surface of described parabolic panel 7 is minute surface, and lower surface is diffuse surface.
When the lower end of described heat conduction slide bar 4 rises in the slideway 30 of adiabatic end seat 3, as shown in Figure 1, the thermoluminescence body 5 of heat conduction slide bar 4 upper end is in the focus place of described parabolic panel 7; Thus make the intensity of illumination of thermoluminescence body 5 be that geometry multiple strengthens; When the lower end of described heat conduction slide bar 4 drops to described lamp stand 1 inside, described thermoluminescence body 5 is in the below of described parabolic panel 7, and uniform illumination is spilt earthward by the diffuse surface again by parabolic panel 7.
Above-mentioned solar street light is when solar irradiation, and as shown in Figure 1, the vacuum heat collection pipe 2 extended along lamp stand 1 can large area daylighting thermal-arrest for state, and by the heat-storage agent of accumulation of heat in lamp stand 1; Simultaneously, make the lower end of the heat conduction slide bar 4 be connected with described thermoluminescence body 5 be in adiabatic end in the slideway 30 of seat, contact with heat-storage agent, then thermoluminescence body 5 generation free electron or hole in a large number under illumination condition, and capture by internal trap; When the sun sets, when night came, state as shown in Figure 2, makes described heat conduction slide bar 4 decline, makes it contact with the heat-storage agent in lamp stand 1, then by this heat conduction slide bar 4, described thermoluminescence body 5 is heated continuously, and the inner trapped electron of thermoluminescence body 5 discharges in a large number from trap, becomes free carrier, and with the centre of luminescence compound of thermoluminescence body 5 inside, release luminous energy; Because the collecting efficiency of vacuum heat collection pipe 2 is high, generally more than 90%, and luminescence is carried out by free carrier and centre of luminescence compound in thermoluminescence body 5 inside, and energy conversion rate is also higher, therefore gross efficiency is far above photovoltaic panel-bulb system; In addition, this solar street light can when fully meeting windproof condition, keeps huge daylighting area large, also abandoned battery.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, all should be included within protection scope of the present invention.
