Variable color temperature lighting luminaire with respective driving luminance and color temperature

Abstract

The invention discloses a variable color temperature lighting luminaire with respective driving luminance and color temperature; the variable color temperature lighting luminaire comprises a luminous module, a driving module and a control module, wherein the driving module is respectively connected to the luminous module and the control module; the driving module comprises a first driving unit and a second driving unit; the control module is used for controlling the driving module to determine the luminance and color temperature of the lighting luminaire; and the control module is used for controlling the first driving unit to determine the luminance of the lighting luminaire and the second driving unit to determine the color temperature of the lighting luminaire.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a variable color temperature lighting fixture driven separately by brightness and color temperature. Background technique [0002] At present, the color temperature of lighting lamps can be regarded as one of the important specifications of lamps. The color temperature is the absolute temperature value of a standard black body with the same light color as the lamp, which is related to the color characteristics displayed by the lamp. Please refer to figure 1 , figure 1 is a chromaticity diagram of an existing color temperature curve, wherein the coordinates of the x-axis and the y-axis respectively represent the chromaticity of different colors. The brightness and color temperature of existing lighting fixtures are fixed when the manufacture is completed. For example, the color temperature of traditional energy-saving light bulbs is determined by the fluorescent material in the bulb. Since ...

AI Technical Summary

Problems solved by technology

The brightness and color temperature of existing lighting fixtures are fixed when the manufacture is completed. For example, the color temperature of traditional energy-saving light bulbs is determined by the fluorescent material in the bulb. Since the brightness and color temperature cannot be adjusted, manufacturers must prepare different Various light bulbs with brightness and color temperature are available for customers to choose, so the cost of inventory, funds and space utilization need to be considered; in addition, the brightness and color temperature marked on the lamps are expressed in numerical values, because it is impossible to understand from the marked values The brightness and color temperature of lamps, and the difference between different values ​​in brightness or color temperature is also difficult to distinguish, so it is not easy for users who want to buy, how to choose lamps that meet their needs
