Description
Technical field
The present invention relates to the lighting device technical field, particularly a kind of electrodeless lamp and fluorescent tube thereof.
Background technology
Inductively coupled plasma (ICP) is known by people has the history in more than 100 year.This type of plasma efficient is widely used in all kinds of processing of plasma aspect with uniformity with it--and plasma etching, plasma surface deposit and crystal growth or the like.And recently, then trend towards of the development of this type of device at lighting field for the research of low pressure inductively coupled plasma.All kinds of induction non-polar light sources of processing with its principle substitute all kinds of conventional light source gradually with its life-span length, high conformity and the higher characteristics of light efficiency.
This type of plasma is the discharge that certain energy that is coupled forms by the external electromagnetic field excitation, but on coupling generator spare position, shape and operation parameter, significant difference is arranged.Research at present two kinds of energy of electromagnetic field coupled modes comparatively widely comprises direct enwinding type of coil and magnetic core ferrite manifold type.
Because the magnetic core ferrite has significant iron loss loss when the high frequency frequency, so have certain efficient and reduce so that its electrodeless lamp as the energy coupling is inevasible.For guaranteeing that it still has higher efficient, this type of electrodeless light source carries out burning-point usually under greater than the 100W situation.The electrodeless lamp of the direct enwinding type of coil has then been avoided the problem of ferrite magnetic core loss.The electrodeless light source made from its principle has good illumination efficiency in small-power (in the 50W) scope.
The comparatively ripe product of developing with this principle then is that PANASONIC in 1991 has at first been released the EVERBRIGHT electrodeless florescent lamp; This sense light directly coils outside spherical cell-shell; Pass to the high-frequency current of 13.65MHz, the luminescence of plasma in the induction cell-shell.The EVERBRIGHT electrodeless florescent lamp light efficiency of 27w was 37lm/w at that time, and average life span is 40000 hours.
The direct enwinding type of coil induction coupling spare is that coil directly is coupled with the sealed light emitting device, produces the high-frequency current excitation electromagnetic field by induction coil, and then in the coupling energy entering sealed light emitting device.As far back as the eighties in last century, the spherical comparatively widely induction coupling of a kind of research luminescent device has just been arranged, it is that RHRS group by IOAPS succeeds in developing.Luminous element is made up of diameter 20mm quartz ball bubble and a cylinder side arm, inner filling liquid mercury and 2 holder argon gas.The cylinder side arm is to place in the attemperator as cold spot, thereby can measure the internal discharge situation under the different cold junction temperature situation.Coil current signal is 100MHz, and current strength is 40～190mA.
