technical field

The invention relates to a control device, in particular to a multi-stage color temperature control device.

Background technique

Compared with the old-fashioned mercury fluorescent lamps, the light-emitting diode grains are more energy-saving and have higher luminance. In addition, mercury fluorescent lamps tend to flicker after aging, causing discomfort and damage to the eyes; Mercury fluorescent lamps are replaced by light-emitting diode crystal grains as light-emitting elements in the lamp tube.

The light emitting element 12 may be a light emitting diode die.

When the light-emitting element 12 receives electric energy from the outside through the electrode device 13 to emit light of a predetermined color temperature, the emitted light is transmitted to human eyes, and different colors of light can be seen according to the color temperature of the light.

The current way to control the color temperature is to control the color temperature of the light emitted by the constituent materials in the light-emitting element 12; Light emitting elements 12 made of different materials are arranged in the body 11 to emit light with different color temperatures when electrified. Therefore, if it is necessary to produce light of different colors due to external occasions and environmental conditions; for example, if you want to change the color from A color temperature to B color temperature, you must first turn off the power by replacing the entire lamp tube 1, and then disassemble the lamp. The lamp tube 1 with color temperature A is installed on the base 900, and the tube 1 with color temperature B is mounted on the lamp base 900. Finally, the power is re-energized so that the emitted light changes from color temperature A to color temperature B, except that the lamp tube 1 needs to be replaced To turn off and turn on the power repeatedly, it is necessary to make lamps 1 with various color temperatures for replacement, which takes a lot of time and material costs, and also results in no flexible space for changing between different colors.
