Description
Technical field
The present invention relates to the illuminating product field, be specifically related to a kind of solar LED (Light Emitting Diode) lamp that has automatic sensitization and can automatically control, such as outdoor lights such as LED street lamp, garden lamp, Landscape Lamps.
Background technology
In recent years, along with the development of the progress of society, science and technology, the energy-conserving and environment-protective theory more and more comes into one's own, and such as in the street lamp field, the LED lamp has obtained large-scale popularization, application just with the characteristic of its energy-conserving and environment-protective.
LED is the abbreviation of semiconductor light-emitting-diode; its basic structure is with an electroluminescent semi-conducting material, places on the leaded shelf, then seals with epoxy resin around it; play the effect of protection internal core, so the LED bulb has good shock resistance.
Because the LED lamp is with respect in the past incandescent lamp, electricity-saving lamp, its power consumption only has about 1/3rd of conventional road lamp, it is little, lightweight to have volume, long service life, high brightness, low in calories, the plurality of advantages such as environmental protection, plasticity sturdy and durable, lucuriant in design, shape are strong has obvious advantage.The internal characteristics of LED bulb has determined that it is a kind of desirable light source, can substitute traditional light source, have more widely purposes and application prospect, and the application of solar energy will further promote the feature of environmental protection of LED lamp.
Because mostly street lamp is employing time switch or the mode of controlling manually at present, this dual mode all can't according to different state of weather such as fine day, cloudy day, rainy day, greasy weathers, accomplish automatically to control road lamp switch, brightness regulation.Like this, easily at fine weather, when sunny, produce unnecessary street lamp and opened phenomenon, if and the cloudy day, thunderstorm, foggy weather etc. that run into burst are during special circumstances, can not accomplish automatic unlatching, cause that road is pitch-dark, the situation of low visibility, both affected people's trip, also can bring certain hidden peril of accident.
Summary of the invention
Technical problem to be solved by this invention is exactly for above-mentioned present situation, and providing a kind of can control automatically, and the Novel LED light of energy-conserving and environment-protective more, and the present invention has adopted following technical scheme.

Sensitization controller of the present invention links to each other with the power supply of LED bulb, MCU controller and LED lamp, and the intensity of illumination signal of described sensitization controller by sensing controlled the LED lamp automatically, and this sensitization controller is connected to the control signal input of MCU controller.The principle of this sensitization controller is to adopt photo resistance as trigger, and is different by extraneous intensity of illumination, regulates voluntarily the brightness of LED bulb.
When the time comes, automatically sensitization, with an automatic light meter of sensitization controller in this solar LED (Light Emitting Diode) lamp, and according to the difference of extraneous light luminance, automatically regulate the brightness of this LED bulb and the switch of control LED lamp, thereby effective energy savings.
Above-mentioned microcontroller (MCU) is the abbreviation of English Micro Control Unit, and the Chinese meaning is micro-control unit, also claims one chip microcomputer (Single Chip Microcomputer) or single-chip microcomputer.This MCU controller is appearance and the development thereof along with large scale integrated circuit, with CPU, RAM, ROM, timer conter and the multiple I/O Interface integration of computer on a slice chip, form the computer of chip-scale, thereby can be different application scenarios, do various combination control such as the street lamp control field.
Sensitization controller of the present invention is installed in the housing parts of LED lamp, usually is arranged on side or the back side of the housing that the LED bulb can't shine.
A kind of solar LED (Light Emitting Diode) lamp of automatic sensitization control type, the housing of its sensitization controller and LED lamp is fixed structure or bascule.When being fixed structure between the two, the position of this sensitization controller in the housing of LED lamp becomes stationary state, irremovable; When being bascule between the two, this sensitization controller can be regulated position and angle on its place housing at any time according to operating position, has made things convenient for different environments for use.
As preferably, also be provided with a radiator on the housing of described LED lamp, the housing of this radiator and described LED lamp is close to, and can better dispel the heat for the LED lamp, thereby can effectively prolong service life of LED bulb.
As seen from the above description, the present invention has compared with prior art had following progress and advantage.
A kind of solar LED (Light Emitting Diode) lamp of automatic sensitization control type, solar power supply apparatus and sensitization controller are applied to LED lamp field, can not only utilize solar cell to gather by day luminous energy, and be stored in the rechargeable battery, when night or light are weak, provide the illumination of more environmental protection for people.
Simultaneously, owing to adopted the sensitization controller at this LED lamp, can change according to the bright surroundings degree, switch on and off the power supply of LED lamp, environment is dimmed around, the intensity of illumination signal that this sensitization controller is sensed is during less than the intensity of illumination threshold value of user preset, and at this moment the control circuit of sensitization controller is connected, and the LED lamp is lighted; When surrounding environment brightened, the sensitization controller controling circuit disconnected, and then the LED lamp extinguishes, and can realize different brightness regulation, need not at ordinary times Artificial Control, and is time saving and energy saving, and can avoid the waste of electric energy, and energy savings is conducive to environmental protection to greatest extent.
