Description
Technical field
The present invention relates to artificial light equipment and for the method for light ray disinfection.Particularly, the present invention relates to photoelectrons
The white light emitting diode (LED) of field and offer bactericidal effect.The present invention relates to integral type light emitting diode construction with
And the application of the disinfection luminaire of ongoing operation.
Background technique
It is well known that ultraviolet light (UV) light source has sterilization sterilization functions, it is very suitable to for sterilizing.Known deep ultraviolet
(short wave ultraviolet) light source effectively inhibits the bacterial growth on surface, therefore is widely used as sterilizing source.However, using short
The drawbacks of wave ultraviolet light source such as mercury lamp, is that short wave ultraviolet has injury to human body, therefore when someone is on the scene, using just
It is restricted.The mechanism of known deep ultraviolet disinfection is to crack DNA molecular, wherein purple of the DNA molecular to wavelength 260-290nm
Outside line has especially strong absorption.
It is also known that longer wavelength can also generate bactericidal effect, but it is based on different physical mechanisms.Known wavelength
Inhibit bacterial growth for the long wave ultraviolet of 365nm, in addition, blue light/purple light also plays the role of similar inhibition bacterial growth.To the greatest extent
The bactericidal effect of pipe blue light/violet wavelength is less strong, but its disinfection light that can be used as ongoing operation.It is well known that wavelength
Intracellular active oxygen (ROS) can be caused to generate for the light of 405nm.These negatively charged oxonium ions can inhibit again in turn
Cell metabolism and the growth for effectively inhibiting such as flora.Although the intensity for sterilizing light has main importance,
It is accumulated dose (the unit J/m accumulated on surface or object2) just finally define sterilization power.
Any low intensity light source with suitable emission spectrum can be used to sterilize, as long as irradiation time long enough,
Certainly, also to have real value.However, same, the on the scene of people is provided with boundary for this light.International Non-ionizing radiation is anti-
The shield committee (ICNIRP) and International Electrotechnical Commission Standard IEC-62471 define international regulations and safety criterion.Equally, state
Committee's definition, ultraviolet wavelength 100-400nm are protected in border Non-ionizing radiation.
If radiation source has short wavelength emissions, such as wavelength is lower than 410nm, and this short wavelength emissions is leading intensity or face
Color, then people would generally not feel well.
Known promotion plant growth and photosynthetic growth light include blue-light source and red light source, are also accompanied by sometimes
White light source.Therefore, they not can solve the problem of antibacterial and sterilization.
104056289 A of CN discloses a kind of light source using light emitting diode and ultraviolet germicidal lamp.However, due to
Ultraviolet light is not suitable for use in general lighting to the adverse effect of human body, this device.

The wavelength of source transmitting is less than 300nm, also due to ultraviolet light is not suitable for general lighting to the adverse effect of human body.
According to our laboratory test, LED and multiple lists that multiple independences and the launch wavelength being spatially separating are 405nm
The combination of only white light LEDs, which can be formed, causes uncomfortable light source.Light source based on the multiple LED being individually encapsulated cannot generate smooth equal
Even light field.In particular, the point light source with intensive short wavelength emissions can make one to feel uneasy.It is necessary to provide a kind of light source, In
In this light source, short wavelength's point light source will not be obvious visual between multiple white light LEDs.However, white light LEDs and 405nm
The physical overlap of LED be not direct or possible.
US 8398264 discloses the example that light source is carried out to spatial mixing.Diffuser plate and Fresnel lens combination make
For providing uniform transmitting, and avoid individual short wavelength's transmitter in source plane directly visible.However, it is known that base
It is more complicated, expensive in the device of diffuser plate.

Higher than ultraviolet wavelength and lower than the peak wavelength emission of 410nm, the transmitting is preferably essentially 405nm, and the hair
The halfwidth penetrated is lower than 30nm.
In general, wavelength conversion material layer is formed on the semiconductor light-emitting source, and there are circuit layers, for connecting
The semiconductor light-emitting source is connect to electric control interface.
The present invention also provides a kind of illuminating equipments for promoting white-light illuminating and continuous disinfection function comprising at least one one
Body formula LED source, the integral type LED source include the first transmitting, can not perceive to human eye, In
In the range of 360-430nm, and halfwidth is less than 30nm；And human eye can be perceived as the second emission peak of white light, it is maximum
Transmitting is in the range of 430-700nm.In a preferred embodiment, there are two types of different types of transmitters, and emission peak is in wave
At long 405nm or at left and right and 450nm or left and right.
Specifically, the present invention is described by the content of the characteristic of independent claims.
The present invention has lot of advantages.
Therefore, the present invention provides a kind of integral LED structure and luminaire for realizing continuous disinfection processing.
The present invention realizes the disinfection by lighting source or luminaire progress, and lighting source or luminaire are by human viewable
White light source will not cause harm to the human body, and will not cause discomfort.Above-mentioned target is by sending out short wavelength emissions and white light
Penetrate what overlapping was realized.This white light source or luminaire are suitable for general lighting purpose, while can be used for providing to exposure
The means that surface or object carry out disinfection.The emitter region generally includes one or more semiconductor light-emitting-diodes, this
Semiconductor light-emitting-diode is technically reliable as optical transmitting set offer light emitting, viable economically.
Wavelength disclosed in this invention is that the use of the electromagnetic radiation of 405nm is safe.This novel LED light source is kept away
