Description
Technical field
The utility model relates to field a kind of band power failure time-delay field of illuminating device, particularly relates to the circuit field of a kind of photovoltaic and civil power handoff functionality LED fluorescent lamp.
Background technology
1907, Round was reported in and has found LED on the SiC.Then, through unremitting research and exploration, the especially Shuji Nakamura outstanding work on blue-ray LED of a large amount of scientific and technical personnel.Nowadays as energy-conserving and environment-protective the 4th generation light source, LED more and more is subjected to favor and the support of national national governments.Led light source is promoted rapidly, and mainly be because of its seven big characteristics: 1) efficiency height: led chip self luminous efficiency has reached 180lm/w.2) environment-protecting asepsis: present widely used fluorescent lamp contains mercury vapour, and LED is all solid state form, does not have uncontrollable pollution.3) life-span is long: the theoretical life-span of LED can reach 100 000 hours.And general osram lamp has only 1000 hours, and fluorescent lamp also is no more than 5000 hours.Obviously, promote the use of LED and not only can save wide variety of materials, and can reduce maintenance cost significantly.4) reliability height: LED is based on the luminous solid luminescence device of semiconductor PN, and is in use not fragile.5) volume is little: the area of led chip generally has only several or tens square millimeters.6) controllability: in process of production, not only can suitably adjust the color of single-chip LED by adjusting the epitaxial wafer component, and can be by controlling brightness, the color that drive current is regulated the LED light fixture.7) light that chemiluminescence: LED sends does not contain infrared radiation, and whole directive property available light.
Summary of the invention
Problem at the prior art existence, the purpose of this utility model provides for the photovoltaic of LED fluorescent lamp and civil power commutation circuit, it is reasonable in design, simple in structure, adopt duplex feeding, can guarantee has mains-supplied when long-term rainy weather, fine day has solar powered, plays the environmental protection and energy saving effect of economy again.
The technical solution adopted in the utility model is:
The photovoltaic and the civil power commutation circuit that are used for the LED fluorescent lamp, comprise solar cell 1, sun can charge to storage battery 3 by charging circuit 2 by battery 1, storage battery 3 is connected by the input of voltage detecting 6 and single-chip microcomputer 7, storage battery 3 is successively by DC/AC 4,6 first inputs are connected with the LED fluorescent lamp in switch control 5,6 second inputs are connected civil power 11 with the LED fluorescent lamp, first output of single-chip microcomputer 7 is connected with charging circuit 2, second output of single-chip microcomputer 7 is connected with switch control 5, the 3rd output of single-chip microcomputer 7 is connected with civil power 11, the 4th output of single-chip microcomputer 7 is connected with alarm 10, and the 5th output of single-chip microcomputer 7 is connected with state indication 9.
The utility model compared with prior art has the following advantages:
1. the utility model is reasonable in design, simple in structure and the circuit part line is simple;
2. adopt the power supply circuits of solar energy and civil power complementation, can suitably reduce the capacity of solar cell and storage battery, reduced the cost of development and use heliotechnics;
4. charging control circuit detects by the voltage to storage battery, when the voltage of storage battery during greater than higher limit, illustrates that storage battery is in saturation condition, does not need to charge in batteries; When battery tension during less than higher limit to charge in batteries, adopt the charging control of two sections Different Strategies, i.e. initial charge and keep and charge two sections.During initial charge, accumulator electric-quantity is few, end is pressed and is in lower limit, but the electric current ability to accept is bigger, the electric current ability to accept of this stage storage battery can be taked to fill soon greater than the fan-out capability of solar cell, after the stage of filling soon finishes, the fan-out capability of solar cell has exceeded the ability to accept of storage battery, and controller will change over to and keep the charging stage.
