Problems solved by technology

However, due to the large volume of the fluorescent tube itself, it is difficult to reduce the volume of this kind of lighting fixture with adjustable color temperature.
In addition, since the two fluorescent tubes need to be turned on at the same time when the light is mixed, the lighting brightness at this time will be twice that of the fluorescent tube with a single color temperature, which will easily cause discomfort to users

Embodiment Construction

[0060] The following will clearly illustrate the spirit of the present invention with drawings and detailed descriptions. After any person skilled in the art understands the preferred embodiments of the present invention, they can change and modify the technology taught by the present invention. depart from the spirit and scope of the present invention.

[0061] The light-emitting diode lamp with adjustable color temperature of the present invention uses two light-emitting diodes with different color temperatures to mix light to achieve the purpose of changing the color temperature. In order to reduce the control cost, the light-emitting diode lamp with adjustable color temperature of the present invention directly uses a three-way switch (3-way switch) as the control element of the lamp, and cooperates with a simple circuit to provide light with three different color temperatures. Purpose.

Abstract

The invention discloses a light-emitting diode lamp capable of adjusting color temperatures. The light-emitting diode lamp comprises a three-section lamp base and a three-section lamp holder. The three-section lamp base comprises a three-section diverter switch. The three-section lamp holder is connected with the three-section lamp base. The light-emitting diode lamp comprises a first light-emitting diode array and a second light-emitting diode array, wherein the first light-emitting diode array and the second light-emitting diode array are different in color temperature. The light-emitting diode lamp capable of adjusting the color temperatures comprises an electric supply detection circuit to detect the conductive state of a first live wire and a second live wire in the three-section diverter switch, so that the first light-emitting diode array emits light or the second light-emitting diode array emits light or the first light-emitting diode array and the second light-emitting diode array emit light in a staggered mode.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, and in particular relates to a light-emitting diode lamp which uses a three-stage switching switch and has the function of adjustable color temperature. Background technique [0002] Fluorescent tubes can change the wavelength of light emitted by the filament through fluorescent powder. Most of the existing lighting fixtures with adjustable color temperature use two fluorescent tubes with different color temperatures to achieve the purpose of mixing light. For example, if two fluorescent tubes are placed in the same lighting fixture, one of the fluorescent tubes has a color temperature of 2600K (warm white light), and the other fluorescent tube has a color temperature of 5600K (cool white light). By operating the switch, you can choose the fluorescent tube to emit light. When two fluorescent tubes with different color temperatures emit light at the same time, you can get a light source with a color ...
