Embodiment 1
[0029] Figure 1 to Figure 3 A specific embodiment of the invention is shown in which figure 1 It is a schematic diagram of the change of color temperature in the present invention; figure 2 It is the warmer logarithmic dimming curve in the brightness level of the present invention; image 3 It is a cold logarithmic dimming curve in the brightness level of the present invention.
[0030] See Figure 1 to Figure 3 , a method applied to the automatic change of color temperature in the process of lamp adjustment, the control of the brightness level of the lamp adopts the logarithmic dimming curve that conforms to the physiological photosensitive characteristics of the human eye, and the following algorithm is used to automatically follow the change of the color temperature of the lamp according to the change of the brightness level Adjustment, so that the brightness and color temperature of the lamps always maintain a certain functional relationship to realize the automatic a...

The invention discloses a method for automatically changing the color temperature in the process of adjusting a lamp. The control of the brightness level of the lamp adopts a logarithmic dimming curve conforming to the physiological photosensitive characteristics of the human eye, and adopts the following algorithm to automatically follow the brightness level of the color temperature of the lamp The change of the lamp bead is adjusted so that the brightness and color temperature of the lamp always maintain a certain functional relationship to realize the automatic adjustment of the color temperature; the specific algorithm is: the color temperatures of the two groups of lamp beads are respectively warm color temperature W and cool color temperature C, and a brightness level x is selected as the cut-off point ;Light source power% is calculated by the logarithmic adjustment light curve value formula: where the value of n varies between 1 and 254, when x is to the left, the dimming curve presents a cooler characteristic, when x is close to 254, the dimming curve presents a partial Warm properties. The invention realizes the automatic control of the linked color temperature in a single dimming control mode, meets the comfort requirements of the human body for the relationship between brightness and color temperature, and satisfies the user's control requirements for lighting highlights and color temperature comfort, and has strong applicability and good practicability.
Description
technical field [0001] The invention belongs to the technical field of lamp adjustment, and in particular relates to a method for automatically changing color temperature in the adjustment process of lamps. Background technique [0002] For the two-color temperature lamps composed of cold light source and warm light source, the control method of its brightness and color temperature is mainly: by adjusting the brightness value and brightness ratio of the two groups of color temperature light sources to achieve the purpose of adjusting brightness and color temperature, usually adjusting brightness and color adjustment The ways of temperature are independent: the brightness can be adjusted under the condition of fixed color temperature value; the color temperature can also be adjusted under the condition of fixed brightness value. In this case, to create a comfortable lighting environment, at least two sets of parameters, brightness and color temperature, must be set, which wil...
