Abstract
The invention relates to a method for automatically adjusting the brightness of an LED lamp of a home gateway. A photoconductive resistor is mounted on the home gateway, an LED, a fixed resistor and the photoconductive resistor are connected in series to form a circuit, and the voltage of the circuit is 3.3 V. The intensity of the LED lamp is changed according to the illumination intensity of light (such as natural light, fluorescent light and incandescent light) capable of being sensed by human eyes. The LED lamp is bright due to the fact that illumination is strong in the daytime, and after the lamp is out at night, no illumination exists, and the illumination of the LED becomes weak and gentle. Thus, the situation that rests of people at night are influenced due to the too strong brightness of the LED lamp is avoided, electricity can be automatically saved, and environment friendliness is achieved.
Description
Technical field
The present invention relates to a kind of home gateway LED automatic brightness adjustment method.
Background technology
At present, along with development and the raising of the health of people, awareness of saving energy of science and technology, Ambient Light Sensor is widely used in during many LED shows, application, the figure of the light sensor that is almost seen everywhere from consumer electronics to automobile.This induction apparatus can be automatically adjusted display brightness according to the light of environment, to reach the function helping to save device battery electricity, the display lamp of current all of home gateway is all Led lamp, but after the brightness of LED dispatches from the factory, it is all fixing brightness, some brightness reaches dazzling degree, allows on the visual perception of people very uncomfortable, particularly to evening, if router is placed on inside bedroom, the brightness of LED, enough has influence on the sleep of individual and also waste household electricity.Current solution is one button that can control LED of installation on home gateway, LED can be switched, this method needs artificially regular by key switch LED, and a lot of home gateways do not have this button, if and by button, LED is extinguished, when network occurs abnormal, bad direct judgement, it is still desirable to open LED.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of home gateway LED automatic brightness adjustment method, it is possible to achieve the brightness of LED is automatically adjusted according to light around.
To achieve these goals, the technical scheme that the present invention takes is as follows:
A kind of automatic brightness adjustment methods such as home gateway LED, it comprises the steps:
(1) LED circuit is first built
Installing a photoconductive resistance on home gateway, LED light emitting diode and fixed resistance being connected with described photoconductive resistance forms a circuit, and the voltage of circuit is 3.3V；
(2) in good time it is automatically adjusted the bright intensity of LED light by any one mode ambient light intensity following
A., when home gateway ambient light becomes strong, photoconductive resistance incident intensity, photoconductive resistance resistance diminishes, and whole circuitous resistance reduces, and electric current increases, and LED brightens；
B. when the light around home gateway dies down, photoconductive resistance incident illumination is weak, and photoconductive resistance becomes big, and whole circuitous resistance increases, and electric current diminishes, and LED is dimmed；
C., around home gateway during unglazed photograph, photoconductive resistance value is maximum, and in circuit, electric current is minimum, and the brightness of LED is the most weak.
Further improving as the present invention, described fixed resistance is 11 Ω.
Compared with prior art, having the beneficial effect that acquired by the present invention:
Home gateway LED automatic brightness adjustment method provided by the present invention, the strong LED of daylight is brighter, and what do not have after turning off the light night that illumination, LED luminance then becomes is faint soft.The night that in so avoiding affects too by force people due to LED brightness has a rest, it is also possible to using electricity wisely automatically, environmental protection.
Accompanying drawing explanation
Accompanying drawing 1 is the circuit diagram of the present invention；
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention is carried out further details of narration.
A kind of automatic brightness adjustment methods such as home gateway LED, first one photoconductive resistance is installed on home gateway, the fixed resistance of LED light emitting diode and 11 Ω is connected with described photoconductive resistance and forms a circuit, the voltage of circuit is 3.3V, when series resistance is for preventing light too weak, electric current is too strong, burns out LED and resistance can limit electric current and linear quadratic control LED luminance again.Physical circuit figure is shown in accompanying drawing 1.
When room has sunlight to irradiate, photoconductive resistance changes the size of its resistance according to current illumination, and illumination is more strong, and the prevention of photoconductive resistance is more little, and electric current is more big, and LED is more bright；The resistance of series connection on circuit, when illumination is very strong, when photoconductive resistance resistance tends to 0, this resistance can allow the electric current of LED be 300mA, the high-high brightness of fixing LED, it is prevented that burn out LED.
When room does not have sunlight, opens electric filament lamp, the photoconductive resistance meeting brightness according to electric filament lamp, adjusting resistance value, thus regulating the brightness of electric current and LED.
When being in night, when closing electric filament lamp inside room, the photoconductive resistance meeting light-source brightness adjusting resistance value according to surrounding, thus regulating the brightness of electric current and LED, when surrounding does not have light, photoconductive resistance value reaches maximum, resistance plus series connection, now electric current is for being fixed as 20mA, thus reaching the brightness of mini light night, it is simple to daily life at night.
Heretofore described photoconductive resistance is the resistor that a kind of resistance value utilizing the photoconductive effect of quasiconductor to make changes with the power of incident illumination, is also called photoconductive detector；Incident intensity, resistance reduces, and incident illumination is weak, and resistance increases.Photoresistor to the sensitivity (i.e. spectral characteristic) of light and human eye to the response of visible ray (0.4-0.76) μm very close to, as long as the light that human eye can be experienced (natural light, fluorescence, incandescence etc.), its change in resistance all can be caused.
The photoconductive resistance of the present invention is prior art, is suitable for the present invention, repeats no more herein.
The above embodiment is only the preferred embodiments of the present invention, and and the feasible enforcement of non-invention exhaustive.For persons skilled in the art, any apparent change under the premise without departing substantially from the principle of the invention and spirit, it is done, all should be contemplated as falling with within the claims of the present invention.
