Description

A kind of LED combination lamp that has illumination and sterilizing function concurrently

Technical field

The utility model relates to a kind of will throw light on and sterilizing function is combined and can be to its LED light fixture of controlling automatically.

Background technology

Aspect ultraviolet sterilization, be exactly at present, destroy and change DNA (DNA) structure of microorganism, make the dead at once or irreproducible offspring of bacterium, reach the purpose of sterilization by ultraviolet irradiation.The ultraviolet UVC wave band of main use, this band ultraviolet is very easy to be absorbed by the DNA of organism, and wavelength is called shortwave sterilization ultraviolet ray again between 200～275nm.Its penetration capacity is the most weak, can't penetrate most clear glass and plastics.The short wave ultraviolet that contains in the daylight is almost absorbed fully by ozone layer.Short wave ultraviolet is very big to the injury of human body, and short irradiation gets final product skin ambustion, and long-term or high strength irradiation also can cause the skin large tracts of land to break away from.On the market ultraviolet germicidal lamp adopts quartz burner, and what send is exactly the UVC short wave ultraviolet, belongs to a kind of low pressure mercury lamp, the same with common fluorescent lamp, utilizes low-pressure mercury-vapor (＜10-2Pa) the back emission ultraviolet ray that is excited.Ultraviolet sterilization belongs to pure physical disinfection method, have simple and convenient, broad-spectrum high efficacy, non-secondary pollution, be convenient to management and realize advantages such as automation, release along with the quartz burner of various new design, the range of application of ultraviolet sterilization is also constantly enlarging, but quartz burner can be aging gradually after using a period of time, ultraviolet irradiation intensity can fail, and needs periodic replacement.And ultraviolet ray can produce very big nocuity to the skin of human body, therefore when being arranged, personnel activity's place generally can not use, send the quartz burner of ozone in addition,, cause the supplying oxygen to body deficiency because ozone can promote the hemoglobin of human body to condense, sensation dizzy, that feel sick takes place, influence healthyly, when reaching＞0.3ppm (mg/m2) especially at ozone concentration, will cause serious injury human body, need to ventilate and handle, therefore also be not suitable for having man-hour to use.

Present lighting and sterilization light fixture all are that branch is arranged, need two to overlap cooling mechanism independently, drive circuit, wiring board and relevant matching component, two of the independent lighting of installing and sterilization light fixture needs installing space independently respectively respectively, need two mounting costs of overlapping light fixtures.The technology of killing the Jun lamp is special, makes difficulty, and price is higher, and because the special nature of quartz glass, makes that the production of bactericidal lamp can not scale, causes the cost of quartzy bactericidal lamp higher, and what hold it back further promotes the use.The ultraviolet ray intensity of the high boron fluorescent tube of lower cost is easy to decay, the uitraviolet intensity 50%-70% when initial that just declines to a great extent after lighting a lamp hundreds of hours, bactericidal effect weakens greatly, and in addition, the cathode injury that causes in the processing has also influenced the life-span of ultraviolet germicidal lamp.And the quartz burner that involves great expense is after lighting 2000-3000 hour, the 80%-70% when uitraviolet intensity also can reduce to initial, because filament and cathode material difference, and with T8, T5 fluorescent lamp UV fluorescent tube with power, can not be with identical ballast driven.To the use operation of ultraviolet lamp, mainly be manual-lock or unlatching UV lamp after in judging sterile zones, having or not personnel by the professional, but artificial control has just brought many maloperations, and can not prevent uncorrelated personnel's operation now.Open lighting or UV bactericidal lamp for a long time and also have the power consumption height, the problem that the life-span is short.

The utility model content

For addressing the above problem, the utility model provides following a kind of technical scheme: a kind of illumination and sterilization multifunctional lamp, its improvement is, described multifunctional lamp comprises illumination LED lamp, ultraviolet LED lamp, described illumination LED lamp, the staggered installation of ultraviolet LED lamp and a shared cover cooling mechanism and a drive circuit, described multifunctional lamp also comprises drive circuit, MPU control module, infrared sensor, electronic switch, control operation plate;

Described drive circuit comprises power transfer module, described MPU control module is a microprocessor, described power transfer module is connected with the LED lamp by electronic switch, wherein the MPU control module is connected with power transfer module, infrared probe, control operation plate respectively, and described control operation plate comprises that illumination/uviol lamp switch, system are provided with keyboard, display screen, identification circuit.

An optimal way again of this programme: described control panel comprises manually and automatic control switch.

This programme has been realized lighting and UV sterilization light fixture are united two into one, and adopt many common component, the totle drilling cost and the installation cost of light fixture have been reduced, utilize infrared automatic circuit, in real time light fixture is controlled, illumination and sterilization power consumption are reduced greatly, the effective time of whole system strengthens greatly and saves a large amount of energy, utilize automatic control continual the sterilization situation to be monitored, greatly improve the security of using the UV bactericidal lamp, avoided occurring the personnel's that accidentally injure in the dissipation process situation.
