New type solar energy LED street lamp
Technical field
The utility model relates to a kind of LED lamp, specifically is a kind of new type solar energy LED street lamp that is used for road lighting.
Background technology
At present the ubiquitous problem of novel solar solar LED street lamp is that power is little, illumination is low, Based Intelligent Control is not enough, is difficult to satisfy the place illumination that highway etc. is had relatively high expectations to illumination.In order to improve power, each state has all strengthened research and development input and the dynamics in solar cell, great power LED technology.Therefore, the development trend of following novel solar solar LED street lamp is high-power, high Based Intelligent Controlization.
That photovoltaic generation has is safe and reliable, noiseless, pollution-free, energy are available anywhere, not limited by the region, need not consume fuel, mechanical rotating part, fault rate is low, easy maintenance, can unattended duty, the cycle of building a station is short, and the specification size is arbitrarily, need not to erect power transmission lines, can combine with building easily etc.These advantages all be conventional power generation usage and other generation modes can't be obtained.Chinese society, rapid economy development provide better development opportunity and space for photovoltaic market, can expect, under the driving of market and ecological environment, China's photovoltaic transforms electric energy and has bigger development space.
At present used novel solar solar LED street lamp existence is not easy to assembling, and cost is higher, is not easy to the defective that running parameter is observed.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of ease of assembly, cost is low and the new type solar energy LED street lamp being convenient to running parameter is observed.
To achieve these goals, the technical solution adopted in the utility model is: new type solar energy LED street lamp, be to constitute by lamp stand, solar cell panel assembly, LED lamp and control cabinet, solar cell panel assembly is connected with control cabinet respectively by electric wire with the LED lamp, it is characterized in that: described control cabinet is located at the bottom of lamp stand, the LED lamp is located at the top of lamp stand, and solar cell panel assembly is located at the top of control cabinet.
Control panel in the described control cabinet is provided with the display screen that 3 charactrons constitute, and a side of described display screen is provided with switches switching the Show Button of demonstration to battery tension, solar cell photovoltaic voltage, street lighting time.
Control panel in the described control cabinet is provided with the time that LED lamp lighting hours is set button is set.Novel solar solar LED street lamp control cabinet, have " start to control at dusk, before midnight street lamp bright entirely (time is adjustable), the time after midnight and daytime street lamp go out entirely " automatic control function, the user can change the before midnight complete bright time of street lamp by the panel button pre-selection parameter and be provided with.
The beneficial effects of the utility model: owing to adopt the structure of combination, can reach the purpose that DIY assembles voluntarily, also have the advantage of ease of assembly; Owing to established the display screen of changeable demonstration, not only saved cost, and be convenient to observation to running parameter; Owing to the button of LED lamp lighting hours has been set, can has regulated and control the lighting hours of LED lamp easily.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, lamp stand; 2, solar cell panel assembly; 3, LED lamp; 4, control cabinet; 5, control panel; 6, display screen; 7, switch the Show Button; 8, the time is provided with button.
The specific embodiment
As shown in Figure 1, new type solar energy LED street lamp, be to constitute by lamp stand 1, solar cell panel assembly 2, LED lamp 3 and control cabinet 4, solar cell panel assembly 2 is connected with control cabinet 4 respectively by electric wire with LED lamp 3, it is characterized in that: described control cabinet 4 is located at the bottom of lamp stand 1, LED lamp 3 is located at the top of lamp stand 1, and solar cell panel assembly 2 is located at the top of control cabinet 4.
Control panel 5 in the described control cabinet 4 is provided with the display screen 6 that 3 charactrons constitute, and a side of described display screen 6 is provided with switches switching the Show Button 7 of demonstration to battery tension, solar cell photovoltaic voltage, street lighting time.
Control panel 5 in the described control cabinet is provided with the time that LED lamp lighting hours is set button 8 is set.Novel solar solar LED street lamp control cabinet, have " start to control at dusk, before midnight street lamp bright entirely (time is adjustable), the time after midnight and daytime street lamp go out entirely " automatic control function, the user can change the before midnight complete bright time of street lamp by the panel button pre-selection parameter and be provided with.
Control circuit in the utility model has following characteristics: novel solar solar LED street lamp control cabinet is by the multi-channel A in the microcomputer chip/D analog to digital conversion circuit, can automatically gather a plurality of running parameters (battery tension, solar cell photovoltaic voltage, the complete bright timing of before midnight street lamp etc.) in the solar power supply system, carry out manual cycle by 3 charactrons to show; Has temperature self-compensation control function: along with the change of environment temperature, can automatically change the setting value of battery management programme-control parameter, to prevent the phenomenon of battery winter " owing charging " or " overcharging " summer; Has multiple auto-protection function: such as solar cell reverse connecting protection, reverse connection of accumulator protection, battery open-circuit-protection, anti-reverse charging protection at night, output short circuit protection etc.
