It is beneficial.
A kind of lamps and lanterns of the colour temperature change for simulated light that the utility model embodiment provides, wherein, the first colour temperature is higher than the
Two colour temperatures.
From upper one embodiment, when the direct current that power supply device 11 is supplied is bigger, lamps and lanterns overall brightness is brighter, most
The colour temperature of the light synthesized eventually is more partial to the first colour temperature, and the direct current that power supply device 11 is supplied is got over hour, the light finally synthesized
Colour temperature is more partial to the second colour temperature, and when the first colour temperature is disposed higher than the second colour temperature, it is possible to realize that power supply device 11 supplies
When the direct current answered is bigger, lamps and lanterns overall brightness is brighter, and colour temperature is also higher, and the direct current that power supply device 11 is supplied is got over hour, lamp
Tool overall brightness is lower, and colour temperature is also lower, this is with sunlight from high noon is just raised to the colour temperature of setting sun natural light and the change of brightness
Change trend be it is consistent, i.e., sunlight initial rise when natural light colour temperature low-light level it is also low, natural light colour temperature high brightness is also big during high noon,
And the natural light color temperature drop low-light level of sunset also reduces.So in the present embodiment, as long as by the natural light of desired simulation
The correspondence for the direct current that colour temperature and the corresponding power supply device 11 of different-colour should provide is stored in power supply device 11, this
Embodiment can simulate the change of the colour temperature of sunlight so that can indoors using the user in the space of the lamps and lanterns
