In addition, the AC/DC converter 100 in the present embodiment is directly connected to the main illumination driver 310, and the current flows out from the AC/DC converter 100, then enters the main illumination light source 320 and the auxiliary illumination driver 410 connected in parallel, and flows out from the auxiliary illumination driver 410, then enters the auxiliary illumination light source 420.

Only one of the auxiliary lighting circuits is shown in fig. 2, and in actual operation, the number of the auxiliary lighting circuits can be adjusted according to actual conditions.
The multi-channel dimming lamp provided by the invention comprises an AC/DC converter 100, a dimming controller 200, a main lighting circuit and an auxiliary lighting circuit; the dimming controller 200 is connected to the main lighting circuit and the auxiliary lighting circuit, and the AC/DC converter 100 is a power supply for the main lighting circuit and the auxiliary lighting circuit; the primary lighting circuit comprises a primary lighting driver 310 and a primary lighting source 320 connected in series; the auxiliary lighting circuit comprises an auxiliary lighting driver 410 and an auxiliary lighting light source 420 which are connected in series, wherein the auxiliary lighting driver 410 is linear constant current driving; the primary illumination source 320 is connected in parallel with the auxiliary illumination circuit. According to the invention, the auxiliary lighting circuit which is connected in parallel with the main lighting circuit in the prior art is only connected in parallel with the main lighting source 320, so that the voltage drop of the whole auxiliary lighting circuit is reduced, namely the voltage obtained by the auxiliary lighting driver 410 is reduced in a phase-changing manner, and the voltage division of the auxiliary lighting driver 410 is in direct proportion to the heat generation, thereby realizing the reduction of the heat productivity of the auxiliary lighting driver 410 and improving the maximum design power of the auxiliary lighting circuit.
On the basis of the first embodiment, a specific connection manner between elements of the multi-channel dimming lamp is further limited, and a second embodiment is obtained, a partial circuit schematic diagram of which is shown in fig. 3 and includes an AC/DC converter 100, a dimming controller 200, a main lighting circuit and an auxiliary lighting circuit;
the dimming controller 200 is connected to the main lighting circuit and the auxiliary lighting circuit, and the AC/DC converter 100 is a power supply for the main lighting circuit and the auxiliary lighting circuit;
the primary lighting circuit comprises a primary lighting driver 310 and a primary lighting source 320 connected in series;
the auxiliary lighting circuit comprises an auxiliary lighting driver 410 and an auxiliary lighting light source 420 which are connected in series, wherein the auxiliary lighting driver 410 is linear constant current driving;
the primary illumination source 320 is connected in parallel with the secondary illumination circuit;
the primary illumination source 320 in parallel with the secondary illumination circuit comprises:
the GND terminal of the auxiliary lighting driver 410 is connected to the cathode of the main lighting source 320, so that the main lighting source 320 is connected in parallel with the auxiliary lighting circuit;
the dimming controller 200 is connected to the auxiliary lighting driver 410 through an isolator.
The difference between the present embodiment and the above embodiments is that how the auxiliary illumination driver 410 is connected in parallel with the main illumination light source 320 is limited in the present embodiment, and the rest of the structure is the same as that of the above embodiments, and therefore, the detailed description thereof is omitted.
The main illumination driver 310 is a step-down type driver, as shown in fig. 3, but it is needless to say that the main illumination driver 310 may be selected according to actual conditions, such as a step-up type, or a flyback type.
In addition, the auxiliary lighting driver 410 is an ic driver or a discrete device driver, wherein the auxiliary lighting driver 410 shown in fig. 3 is an ic driver, the illustrated embodiment has two auxiliary lighting circuits, wherein VBUS + represents a power supply line, and VLED 2-and VLED 3-represent cathodes of the auxiliary lighting sources 420 of the two auxiliary lighting circuits, respectively, and in contrast, the circuit diagram of the multi-channel dimming lamp driven by an ic in the prior art is shown in fig. 1, wherein the main lighting circuit, the auxiliary lighting circuit 1 and the auxiliary lighting circuit 2 are connected in parallel, and the circuit diagram of the discrete device driver is shown in fig. 5.
In the present embodiment, it is specifically defined that the originally grounded GND terminal of the auxiliary lighting driver 410 is connected to the cathode (i.e., VW-terminal in the figure) of the main lighting source 320, so that the auxiliary lighting circuit is connected in parallel with the main lighting source 320 and in series with the main lighting driver 310, where there are many auxiliary circuits, but the number and power of the auxiliary circuits are limited by the total power of the circuit where the main lighting driver 310 is located, and the total brightness is the total power, which is dynamically controlled by the current magnitude, in the case of light source voltage determination.
As a specific example, the high-end intelligent LED lamps with cooling and heating color temperature adjustment in the current market are basically equal in cooling and heating power, for example, the cooling and heating powers are respectively 80W, the heating light is the main lighting in the above proposal, and the maximum power is 80W, but only about 40W is generally used, and the remaining 40W can drive two auxiliary lights (or three color RGB auxiliary lights), and the two auxiliary lights can also achieve independent cooling and heating color temperature adjustment (or color RGB adjustment). Thus, a dynamic adjustment of the main and auxiliary lighting is formed. But in practice, more cold color temperatures are used and less warm color temperatures are used for the user. Therefore, for the design of the driving circuit, electronic materials of the warm lamp are wasted, the cost is high, and by adopting the specific implementation mode, the circuit which is driven by the warm lamp and is not fully utilized (simultaneously, the current of the warm lamp and the current of auxiliary lighting are borne), so that the manufacturing cost is greatly reduced.
In addition, since the GND terminal of the auxiliary lighting driver 410 is not grounded any more, that is, the auxiliary lighting driver 410 and the dimming controller 200 are not grounded any more, which results in that the electrical signal sent by the dimming controller 200 cannot be directly received and identified by the dimming controller 200, the embodiment also converts the electrical signal sent by the dimming controller 200 into the electrical signal identifiable by the auxiliary lighting driver 410 through the isolator, thereby ensuring stable and reliable signal transmission.
On the basis of the second embodiment, a specific connection manner between elements of the multi-channel dimming lamp is further limited, and a third embodiment is obtained, a partial circuit schematic diagram of which is shown in fig. 4 and includes an AC/DC converter 100, a dimming controller 200, a main lighting circuit and an auxiliary lighting circuit;
the dimming controller 200 is connected to the main lighting circuit and the auxiliary lighting circuit, and the AC/DC converter 100 is a power supply for the main lighting circuit and the auxiliary lighting circuit;
the primary lighting circuit comprises a primary lighting driver 310 and a primary lighting source 320 connected in series;
the auxiliary lighting circuit comprises an auxiliary lighting driver 410 and an auxiliary lighting light source 420 which are connected in series, wherein the auxiliary lighting driver 410 is linear constant current driving;
the primary illumination source 320 is connected in parallel with the secondary illumination circuit;
the primary illumination source 320 in parallel with the secondary illumination circuit comprises:
the GND terminal of the auxiliary lighting driver 410 is connected to the cathode of the main lighting source 320, so that the main lighting source 320 is connected in parallel with the auxiliary lighting circuit;
the dimming controller 200 is connected to the auxiliary lighting driver 410 through an isolator;
the isolator is a photoelectric coupler.
The difference between the present embodiment and the above embodiments is that the present embodiment defines a specific type of the isolator, and the rest of the structure is the same as that of the above embodiments, and is not further described herein.
The isolator is specifically limited to be a photoelectric coupler in this specific embodiment, that is, the electrical signal from the dimming controller 200 is converted into an optical signal through the light emitting diode in the photoelectric coupler, and the optical signal is absorbed by the photoelectric sensing element on the other side and converted into the electrical signal again, so that the geometric transformation of the strength of the electrical signal is realized, the universality is strong, and the two ends of the photoelectric coupler are not in direct electrical contact, so that the safety is good, the working stability is strong, and of course, other isolators can be selected according to actual conditions.
Fig. 4 illustrates the photo coupler, wherein the electrical signal PWM 2' transmitted from the dimming controller 200 is modulated by the photo coupler and converted into the electrical signal PWM2 recognized by the auxiliary lighting driver 410. Port 3 in the figure is also connected to the cathode of the primary illumination source 320.
