The utility model is composed of a solar-energy battery board, a storage battery, a controller. The solar-energy battery board charges the storage battery through the controller; the solar-energy battery board and the storage battery can simultaneously or respectively provide electricity to a light source. The utility model is characterized in that the light source is a light of cermet halogenide, the output of the controller is connected to an electronic stabilizer, and the output port of the electronic stabilizer is connected to the light of cermet halogenide.

Description

Solar street light

(1) technical field

The utility model relates to the solar lighting field, is specially solar street light.

(2) background technology

In the solar energy illuminating product, the application facet of the solar energy garden lamp of view lamp ﹠ lantern, Lawn lamp etc. shows unique characteristics, and its effect is better, accepts for users.Yet as the solar street light of traffic route night illumination, certain traffic lighting hierarchy level lighting standard is arranged: the through street is that 20Lx, trunk roads are that 15Lx, secondary distributor road are that 8Lx, Zhi Ganlu are 5Lx.At present, be applied in the light source on the solar street light, usually use HF lamp without electrodes, though the life-span is longer, its light efficiency is general, only about 60Lx, for the road surface average illumination that reaches regulation requires, also will guarantee certain lighting hours, just require the light source power of solar street light enough big, reach certain luminous flux, the solar module that necessary like this allocating power is enough big and the battery capacity of energy storage.Because solar module costs an arm and a leg at present, causes the cost of solar street light too high, can't compete mutually with the street lamp of mains-supplied, can not replace the big conventional street lamp of power consumption fully.

(3) summary of the invention

At existing solar street light, its cost height, can't compete mutually with the street lamp of mains-supplied, the shortcoming that can not replace the big conventional street lamp of power consumption fully, the utility model provides another solar street light, the existing relatively Solar lamp of its cost will reduce greatly, is beneficial to and popularizes.

Its technical scheme is such: it comprises solar panel, storage battery, controller, described solar panel is realized charge in batteries by controller, described solar panel, storage battery can be at the same time or separately to light source power supplies, it is characterized in that: described light source is a ceramic gold-halogen lamp, the output of described controller connects electric ballast, and the output of described electric ballast connects described ceramic gold-halogen lamp.

It is further characterized in that: described controller comprises overcharge protection circuit, over-discharge protection circuit, light-operated circuit, CPU treatment system; described CPU treatment system connects output circuit, and described CPU treatment system comprises interruption reset condition circuit, power circuit, timing circuit, circuit of clock frequency and CPU processor.

The utility model adopts after the said structure, because of the luminous efficiency of ceramic gold-halogen lamp will exceed 50% than HF lamp without electrodes, reach about 90Lx, the power of the solar module that is complementary like this is corresponding with the capacity of storage battery to have reduced by 50%, greatly reduce the integrated cost of solar street light, strengthened the competitiveness in market, be beneficial to the popularization and the use of solar street light, thereby avoided existing solar street light, its light source uses HF lamp without electrodes, and the solar module power that need mate battery capacity big, energy storage is also big.Cause the cost of solar street light too high, the shortcoming that can't popularize.

(5) embodiment

See Fig. 1, Fig. 2, the utility model comprises solar panel, storage battery, controller, described solar panel is realized charge in batteries by controller, described solar panel, storage battery can be powered to ceramic gold-halogen lamp at the same time or separately, the output of described controller connects electric ballast, and the output of described electric ballast connects described ceramic gold-halogen lamp.Described controller comprises overcharge protection circuit, over-discharge protection circuit, light-operated circuit, CPU treatment system, and described CPU treatment system connects output circuit.See Fig. 1, form solar module by solar panel, storage battery, diode D1, piezo-resistance Rv, fuse FU1; Form overcharge protection circuit by resistance R 1, R2, R3, R4, R5, R6, adjustable voltage stabilizer TL1, Q1P-MOS pipe, LED1; Form light-operated circuit by resistance R 7, R8, R9, R10, R11, R12, capacitor C 1, diode D2, LED2; Form over-discharge protection circuit by resistance R 13, R14, R15, R16, adjustable voltage stabilizer TL2; The CPU treatment system comprises by resistance R 17, capacitor C 2 forms the interruption reset condition circuit; The power circuit of forming by resistance R 17, R18, adjustable voltage stabilizer Z1, capacitor C 3; The timing circuit of forming by R19, R20, R21; Form circuit of clock frequency and CPU processor by capacitor C 4, C5, crystal oscillator Y1, the CPU treatment system connects output circuit, two output circuits are arranged among Fig. 1, form by resistance R 26, R27, R28, R29, triode Q4, fuse FU3, LED3, Q5P-MOS pipe and resistance R 23, R22, R24, R25, triode Q2, fuse FU2, LED4, Q3P-MOS pipe respectively, follow-up connection electric ballast of output circuit and Metal halogen lamp are not expressed electric ballast and Metal halogen lamp among Fig. 1.Describe control procedure of the present utility model below in conjunction with Fig. 1: during sunshine, solar module produces certain photovoltaic voltage, and energy storage battery is charged, and after storage battery was full of electricity, Q1P-MOS pipe conducting in the overcharge protection circuit was by resistance R 5 discharges.When light was reduced to certain degree, node A was everywhere in low level in the light-operated circuit, and low level signal is by the back output high level relatively of the comparator in the CPU processor, again by follow-up output circuit to electric, light ceramic gold-halogen lamp.Produce instantaneous pressure by electric ballast earlier during startup, see Fig. 3, high voltage pulse makes electrode discharge in the ceramic core 1, temperature uprises in the arc lamp tube, luminous agent vaporization and ionization form plasma gas, plasma gas discharge, electrode conduction, keep operate as normal by the ballast ballast again, 2 is that glass bulb, 3 is that support, 4 is that air separator, 5 is that lamp socket, 6 is lamp base.The ballast that uses in the utility model is 12V or 24V dc electronic ballast.During discharge, when the voltage of storage battery was lower than set point, node B place transferred high level to by low level in the overdischarge road, and high level signal passes through relatively back output low level of the interior comparator of cpu controller, and follow-up output circuit stops external power supply.That controller for solar has is light-operated, time control function and overcharge, cross and put defencive function, can effectively protect storage battery to discharge and recharge normally, increases the service life.
