Description
Technical field
The present invention relates to the LED lighting technical field, relate in particular to a kind of LED lamp control system and control method.
Background technology
Light-emitting diode (LED, Light Emitting Diode) is a kind of semiconductor solid luminescence device, and it utilizes semiconductor PN as luminescent material, can directly electricity be converted to light.The structure of LED mainly is made up of semiconductor PN, electrode and optical system.
The luminescence mechanism of LED is: the terminal voltage of PN junction constitutes certain potential barrier, and when adding forward bias voltage, potential barrier descends, and the majority carrier in P district and N district spreads to the other side; Because electron mobility is more much bigger than hole mobility,, constitute injection to P district minority carrier so a large amount of electronics can occur to the diffusion of P district; The energy that hole-recombination on these electronics and the valence band, compound tense obtain discharges with the form of luminous energy.
Studies show that in a large number, luminous environment has direct influence to health, illumination all can exert an influence to many aspects such as people's physiology, psychology, even the light that people are accepted by day can have influence on the nighttime sleep quality, studies show that the vertical illumination at human eye place and sleep quality have the positive relation.There are light pollution such as stroboscopic, ultraviolet radiation, electromagenetic wave radiation, thermal radiation and dazzle in common incandescent lamp and fluorescence lamp ﹠ lantern lighting source.And LED light has advantages such as no stroboscopic, no ultraviolet radiation, no electromagenetic wave radiation, low thermal radiation, adds and should eliminate dazzle with the light diffusion technique, makes it to become real healthy light source.
And because the luminous efficiency of led light source improves constantly, stability is more reliable, and price is also progressively descending, thereby provides fabulous opportunity for the LED Lighting Industry.No matter at illumination, or the general illumination aspect, led light source all has huge market and development prospect.
