In addition, the first annular bracket 11 has a first annular conductive member 111 and a second annular conductive member 112 opposite to each other, and two ends of each first LED wick 12 respectively have

conductive electrodes

121 and 122, so that the first LED wick 12 can be electrically connected to the first annular conductive member 111 and the second annular conductive member 112 through the

conductive electrodes

121 and 122 respectively and be disposed on the first annular bracket 11 in parallel; the second annular frame 13 also has a third annular conductive member 131 and a fourth annular conductive member 132 opposite to each other, and two ends of each second LED wick 14 also have

conductive electrodes

conductive electrodes

141 and 142, respectively, and disposed on the second annular frame 13 in parallel. On the other hand, the end of the first conductive supporting member 311 away from the stem 30 is electrically connected to the two annular conductive members 112 and the third annular conductive member 131 as a common electrode; the ends of the second conductive supporting element 312 and the third conductive supporting element 313 away from the stem 30 are electrically connected to the first ring-shaped conductive element 111 and the fourth ring-shaped conductive element 132, respectively. In some other possible embodiments, when assembling the multispectral LED lamp 1, an exhaust pipe (not shown) inside the stem 30 may be used to evacuate the air from the accommodating space 61, or an inert gas, such as: the low-viscosity high-thermal-conductivity gas is filled in the accommodating space 61 to improve the heat dissipation effect of the light emitting module 10.

Referring to fig. 1A, the light head 50 is combined with the outer surface of the casing 60 from the other side opposite to the stem 30 and covers the opening 601. The base 50 includes a metal screw housing 51 and an external contact 52 connected to the metal screw housing 51. The driving power module 40 is disposed in the lamp head 50, and the driving power module 40 can be connected to one end of the conductive supporting member 31 penetrating through the core column 30 and electrically connected to the first annular bracket 11 and the second annular bracket 13, respectively. In the present embodiment, the second conductive supporting element 312 and the third conductive supporting element 313 are both negative power circuits, and the first conductive supporting element 311 is a positive power circuit, so that the driving power module 40 can respectively drive the first LED wick 12 or the second LED wick 14 to emit light by using the positive and negative power circuits of the conductive supporting element 31.

The driving power module 40 converts the received ac power into dc power, and provides the dc power to the first LED wick 12 or the second LED wick 14 of the light emitting module 10 through the positive and negative power lines of the conductive support 31. For example, when the driving power module 40 is a wall-surface open-type control module, when a user turns on a switch of an external power for the first time, the driving power module 40 may drive the first LED wick 12 to emit the first light L1, and the second LED wick 14 does not emit light but does not pass current; when the user turns off the switch of the external power supply and turns on again, the driving power module 40 may drive the second LED wick 14 to emit the second light L2, and the first LED wick 12 does not emit light when no current passes through it; when the user turns off the switch of the external power supply again and turns on the switch again, the driving power module 40 can simultaneously drive the first LED wick 12 to emit the first light L1 and drive the second LED wick 14 to emit the second light L2.

In the present embodiment, the wavelength of the first light L1 has higher relative intensity in the range of 430nm to 480nm and the range of 580nm to 680nm (as shown in fig. 2A); the wavelength of the second light L2 also has a relatively high relative intensity in the range of 430nm to 480nm, but the relative intensity in the range of 480nm to 630nm is relatively flat (as shown in fig. 2B). When the driving power module 40 simultaneously drives the first LED wick 12 to emit the first light L1 and the second LED wick 14 to emit the second light L2, the first light L1 and the second light L2 are mixed to form a light with a mixed spectrum (as shown in fig. 2C). Therefore, a user can control the light emitting module 10 to emit light rays with different spectrums according to the requirements of the environment and the field, and the practicability and the universality of the lighting lamp can be improved.
