Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be defined by the claims
Implement with the multitude of different ways covered.
As it is shown in figure 1, the invention provides a kind of LED lamp bar light modulation color-temperature regulating circuit, drive including external Dimmable LED
Power supply the 1, first colour temperature LED strip connection circuit the 2, second colour temperature LED strip connection circuit the 3, first current-limiting resistance 4 and the second current-limiting resistance 5,
Wherein, external Dimmable LED drives the positive pole of power supply 1 to join positive terminal and second colour temperature of circuit 2 with the first colour temperature LED strip simultaneously
The positive terminal of LED strip connection circuit 3 connects, and the negative pole end of the first colour temperature LED strip connection circuit 2 passes through the first current-limiting resistance 4 with external
Dimmable LED drives the negative pole of power supply 1 to connect, the negative pole end of the second colour temperature LED strip connection circuit 3 by the second current-limiting resistance 5 with
External Dimmable LED drives the negative pole of power supply 1 to connect；LED number in first colour temperature LED strip connection circuit 2 is not equal to the second color
LED number in temperature LED strip connection circuit 3, the first color when described external Dimmable LED driving power supply 1 is brought to high-high brightness
The electric current flow through in temperature LED strip connection circuit 2 is equal to the electric current flow through in the second colour temperature LED strip connection circuit 3.
Wherein, the first colour temperature LED strip connection circuit 2 and the second colour temperature LED strip connection circuit 3 have different colour temperature (such as, the
The colour temperature of color temperature LED strip connection circuit 2 is higher than the colour temperature of the second colour temperature LED strip connection circuit 3), and the LED quantity of the two
(such as, the LED quantity in the first colour temperature LED strip connection circuit 2 is more than the LED number of the second colour temperature LED strip connection circuit 3), therefore
Constitute non-equilibrium structure.
When external Dimmable LED drives power supply 1 to be in high brightness output state, output pressure is high for it, electric current is big, the first color
The driving electric current of temperature LED strip connection circuit 2 and the second colour temperature LED strip connection circuit 3 is suitable, and mixing colour temperature is higher；When external tunable optical
When LED drive power 1 is in low-light level output state, output pressure is relatively low, the first colour temperature LED strip joins the driving electric current on circuit 2
Fall is much larger than the driving electric current fall on the second colour temperature LED strip connection circuit 3, in the mixed light that LED lamp bar sends
Low colour temperature ratio raises, and makes the overall color temperature of mixed light reduce, it is achieved thereby that light modulation adjusts the purpose of colour temperature simultaneously.
Owing to have employed technique scheme, if two power input lines of the present invention, it is not necessary to special tunable optical and tune
Color-temperature controller, can access on original only dimming function circuit and realize the tunable optical function with adjustable color temperature.
As it is shown in figure 1, the embodiment of the present invention can arrange the first colour temperature LED strip connection circuit 2 and second that many groups are in parallel
Colour temperature LED strip connection circuit 3.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
