Abstract

The utility model discloses a semiconductor lighting lamp used in the non-urban power area, comprising a solar cell, a hand-held power generator, a lithium ion group battery with a charging controller and an LED lighting lamp. The solar cell and the input end of the hand-held power generator are connected with the input end of the charging controller in the lithium ion group battery. The control output ends of the charging controller are connected with the two electrodes of the group battery and the two ends of the lighting lamp. The utility model adopts the LED lighting lamp with minimum power consumption. Compared with the incandescent lamp, the power can be saved more than 95 percent. The lighting request can be ensured only by a solar cell with small required power and an accumulator with small capacitance. The hand-held power generator adopts the rare-earth permanent-magnet three-phase AC hand-held power generator whose volume and weight are all very small. When encountering the continuous rainy days, the accumulator can be charged conveniently to satisfy the lighting request.

Description

The semi-conductor lighting lamp of solar cell and hand-held generator powered

Affiliated technical field

The utility model belongs to field of illumination lamp technology, relates to a kind of semi-conductor lighting lamp that can use in no civil power area.

Background technology

At present in the pastoral area, grassland and the illuminating lamp of no civil power area use such as poor mountain area, borderland be generally incandescent lamp or common electricity-saving lamp.The power consumption of these illuminating lamps is bigger, must be equipped with very big solar cell of power and the very big battery of capacity during general work, so cost is very high, the poverty-stricken area is difficult to use; If meet continuous wet weather or wind and snow weather, the illumination in vast no civil power areas such as pastoral area, grassland or poor mountain area is just more difficult.

The utility model content

The purpose of this utility model is the problem that prior art exists is solved, and provides a kind of novelty simple in structure, cost is low, power consumption is little, favorable working performance, be particularly suitable at the solar cell of no civil power area use and the semi-conductor lighting lamp of hand-held generator powered.

Be used to realize that the technical solution of foregoing invention purpose is such: the solar cell that is provided and the semi-conductor lighting lamp of hand-held generator powered are made up of the lithium ion battery group and the LED illuminating lamp of solar cell, hand-held generator, band charge controller, the input of solar cell and hand-held generator is connected to the input of charge controller in the lithium ion battery group, it is extreme that the control control output end of charge controller is added in lithium ion battery group two, and lithium ion battery group the two poles of the earth terminate at the two ends of LED illuminating lamp.The actual use of this illuminating lamp is: when fine, charging control circuit is to lithium ion cell charging in the lithium ion battery group for solar cell, and behind the full charge, lithium ion battery changes floating charge state automatically over to, for the illumination of LED illuminating lamp; When running into continuous wet weather or wind and snow weather, available hand-held generator is to lithium ion cell charging, for the illumination of LED illuminating lamp.In recent years, the semiconductor lighting technology develops rapidly, development and production go out the minimum LED illuminating lamp of power consumption both at home and abroad, the utility model promptly adopts this kind illuminating lamp, this lamp is compared with incandescent lamp commonly used, can economize on electricity more than 95%, the battery that solar cell that a required power is very little and capacity are very little just can guarantee the requirement of throwing light on; In addition, the used hand-held generator of the utility model adopts this area to research and develop successful rare earth permanent magnet three-phase alternating current hand-held generator recently, volume, the weight of this generator are all very little, when running into continuous wet weather or wind and snow weather, can charge to battery easily, satisfy lighting requirement.

The specific embodiment

Referring to accompanying drawing, the semi-conductor lighting lamp of solar cell described in the utility model and hand-held generator powered partly is made up of solar cell 1, hand-held generator 2, the lithium ion battery group 3 of being with charge controller and LED illuminating lamp 4 etc.In example structure shown in Figure 2, owing to adopt lighting power to have only 1W (3.3V, LED illuminating lamp 4 350mA), in order to guarantee continuous illumination more than 5 hours at night, solar cell 1 can be selected 5W amorphous solar panel for use, the output voltage of solar cell 1 owing in the lithium ion battery group 3 charging control circuit is housed again, so can directly insert battery pack 3.Hand-held generator 2 adopts rare earth permanent magnet three-phase alternating current hand-held generator, in order to keep output dc voltage, three-phase bridge rectifier circuit is equipped with in portion within it, same owing in the lithium ion battery group 3 charging control circuit is housed, also can directly insert battery pack 3 so hand the output voltage of generator 2.The operating voltage of LED illuminating lamp 4 is generally 3.3V～3.6V, therefore can select the monomer lithium ion battery for use, the operating current of 1W illuminating lamp is about 350mA, but select for use the continuous illumination of 2～3Ah battery about 10 hours, in order to reduce cost and to improve security, the battery E of lithium ion battery group 3 selects the LiMn2O4 ion battery for use.In course of normal operation, the output voltage of solar cell and hand-held generator will change within the specific limits, thereby must in lithium ion battery group 3, charge controller be set, in order to reduce cost and to improve reliability, selected the considerably less linear-charging controller of outer member in the utility model in the lithium ion battery group for use, its structure as shown in Figure 2.Model is that the device of ISL6291 is to include the lithium ion cell charging controller that element is adjusted in series connection among the figure, the output voltage of solar cell 1 and hand-held generator 2 during work (allowing to change between 4.3V～10V) directly is added to the input of ISL6291, battery pack E maximum constant charging current is set (maximum charging current is 1A) by resistance R 1, after battery tension reaches 4.3V, charger changes constant-voltage charge automatically over to, after this charging current reduces gradually, after charging current was reduced to certain numerical value (this numerical value is set by resistance R 2), battery pack stopped charging.The effect of capacitor C 1 is input filtering among Fig. 2, and the effect of capacitor C 2 is to set the quick charge time.

In addition, in order to ensure 3 safe and reliable the discharging and recharging of lithium ion battery group, in battery pack, also should add the lithium ionic battery protection circuit that is used to prevent battery pack overcharge, overdischarge, overcurrent etc.Example structure shown in Figure 3 is extremely to be equipped with AIC1811 type lithium ion battery group charge-discharge protection circuit at battery pack E two; it is that integrated chip and transistor switch V1, the V2 etc. of AIC1811 constitute by model; outsidely during use only need to insert charging control and discharge control MOSFET, V1 and V2 can finish overcharge, functions such as overdischarge, overcurrent protection.
