LED lamps are one new light source that has the advantages of small volume, low electricity consumption, long service life, high luminous efficiency, non-toxicity, environmental friendliness, long life and rich colors.

In current LED lamps, a single LED can only achieve one color temperature and cannot be adjusted. The lighting effect of the low color temperature lamp is warm, the lighting effect of the high color temperature lamp is cold, and when the external environment changes, the light and environment of the lamp cannot be harmonized, which affects the lighting and decoration effect .

The newest LED dimming circuit and technology employs pulse width modulation technology to change the brightness of the LED, but the change in LED color temperature is small and does not exceed 100K color temperature.

In the LED lamp capable of realizing the plurality of color temperatures, the white light chip, the yellow light chip and the red light chip are fixedly connected to the heat conduction path of the LED lamp substrate.
In the LED lamp capable of realizing a plurality of color temperatures, the color temperature of 5000K to 7000K is realized by connecting the positive and negative electrodes of the white light chip.
In the LED lamp capable of realizing a plurality of color temperatures described above, the color temperature of 3500K to 5000K is realized by connecting the positive and negative electrodes of the white light chip and the yellow light chip.
