Embodiment
To make to have further understanding to the purpose of the present invention, construction, feature and its function, hereby coordinate embodiment detailed
It is described as follows.
The schematic diagram for the electronic installation that Fig. 2 provides for one embodiment of the invention, as shown in Fig. 2 electronic installation 200 includes the
One illuminating module 210A, the second illuminating module 210B, the auxiliary drive unit 230A of main driver element 220 and first.First lights
Module 210A and the second illuminating module 210B can be light emitting diode, and can launch the first light and the second light respectively,
Main driver element 220 has output end 220OUT, output end 220OUTOptionally to provide driving current in the first luminous mould
Group 210A and the second illuminating module 210B, main driver element 220 has the first control end 220CA, the first control end 220CAIt is used to
The the first illuminating module 210A power supply period is controlled, main driver element 220 separately has the second control end 220CB, the second control end
220CBIn power supply period to control the second illuminating module 210B, Fig. 2, when switch SW1 coupling output ends 220OUTWhen (open
When closing SW1 closures), output end 220OUTThe first high operation voltage level is provided to the first illuminating module 210A, now output end
220OUTOutput current A1 flows through the earth terminal 220 that the first illuminating module 210A flow to main driver element 220GND, the first luminous mould
Group 210A sends the first light；When switch SW2 coupling output ends 220OUTWhen closure (switch SW2), output end 220OUTCarry
The second illuminating module 210B is given for the second high operation voltage level, now output end 220OUTOutput current A2 flows through second and lighted
Module 210B flow to the earth terminal 220 of main driver element 220GND, the second illuminating module 210B sends the second light.
Other first auxiliary drive unit 230A output end 230AOUTElectric current A1 ' can be provided in the first illuminating module
210A, electric current A1 ' and electric current A1 have identical wavelength, and electric current A1 ' is via the first illuminating module 210A to the first process auxiliary drive
Unit 230A earth terminal 230AGND, wherein when electric current A1 or A2 increase, the first illuminating module 210A or the second illuminating module
210B light luminance can increase, but when the first illuminating module 210A or the second illuminating module 210B is light emitting diode,
Electric current A1 or A2 need to be defined within a maximum and can not continuously light, in order to avoid the service life of accelerated luminescence diode
Reduction, therefore when supplies of the electric current A1 or A2 in maximum current value, need to cause to light two when reaching a scheduled time
The current value of pole pipe supply is reduced to a predetermined current value, and when the current value of light emitting diode is this predetermined current value, hair
Optical diode continuously lights, so, due to reaching the current value reduction provided during the scheduled time for light emitting diode, luminous two
The service life of pole pipe can still maintain certain depth, in this way, when light emitting diode is in the state of high current high brightness, due to
The problem of service life of light emitting diode, causes high current high brightness limited duration, the use aspect palpus of light emitting diode
State of the compartment of terrain in high current high brightness is needed for transient mode (burst mode), i.e. light emitting diode.
Fig. 3 be Fig. 2 shown in electronic installation 200 in the first illuminating module 210A electric currents timing diagram, in the first period T1
Main driver element 220 provides electric current A1 to the first illuminating module 210A, at the same time, the first auxiliary drive unit 230A and first
Illuminating module 210A disconnects, and the first auxiliary drive unit 230A does not provide any electric energy to the first illuminating module 210A and supplied,
Main driver element 220 can adjust the first light of the first illuminating module 210A transmittings in the first period T1 according to electric current A1 intensity
The intensity of line；In the second period T2, main driver element 220 provides electric current A2 to the second illuminating module 210B, because main driving is single
Member 220 can only once drive an illuminating module, therefore in the second period T2, and main driver element 220 stops providing electric energy to the
One illuminating module, the substitute is the first auxiliary drive unit 230A and is sent out in the second period T2 there is provided electric current A1 ' to first
Optical mode group 210A, therefore can be lighted simultaneously and electric in the second period T2, the first illuminating module 210A and the second illuminating module 210B
The brightness of sub-device 200 can be increased.
In addition, the first illuminating module 210A is different from the light that the second illuminating module 210B is sent, and in response to image
The demand of different colours, can dynamically adjust the first illuminating module 210A and the second illuminating module 210B launch the first light with
Second light, further, can be carried out the colour mixture of color, the first period T1 by the first period T1 and the second period T2 length adjustment
It can be periodic switching with the second period T2, when the color of the first light of needs is more, improve the first period T1 length
The length of degree and the second period T2 of reduction, vice versa；In order to avoid improving brightness, (electric current A1 ' is supplied to the in the present invention
One illuminating module 210A) and the mixing of color is had influence on, cause user to the sticky feeling of color, the present invention need to be limited in addition
Electric current A1 ' is less than electric current A1, and the first illuminating module 210A for making extra second period T2 luminous reduces interference, also makes first simultaneously
Illuminating module 210A electric current is reduced to A1 ' by A1, is unlikely to so that the first illuminating module 210A electric current maintains one always
Individual high current value A1 and influence its service life.
