Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as Figure 1-2 As shown, a PWM power adjustment method suitable for color temperature lamps includes a warm light adjustment module for controlling the power output of warm light, and a cold light adjustment module for controlling the power output of cold light. The connection between the module and the cold light adjustment module is characterized in that it includes the following steps:

[0023] 1) Turn on the controller, warm light adjustment module, and cold light adjustment module simultaneously;

[0024] 2) When the color temperature is at the lowest A1 position, the controller keeps the PWM output power of warm light at the maximum and rem...

Abstract

The invention relates to a PWM power adjustment method suitable for a color temperature lamp. A warm light adjusting module used for controlling warm light power output and a cold light adjusting module used for controlling cold light power output are included, wherein a controller is connected with both the warm light adjusting module and the cold light adjusting module. Except for the A1 position where the color temperature is lowest, the PWM output power of the warm light is the largest and the PWM output power of the cold light is 0, and the PWM output power of the cold light at the A3 position with the highest color temperature is the largest and the PWM output power of the warm light is zero, for the color temperature at the remaining position, the PWM output power of at least eitherthe warm light or the cold light is maximized, the PWM output power of the other of the warm light or the cold light is combined to achieve final power output, so the output power is maximized to improve output efficiency.

Description

technical field [0001] The invention relates to an adjustment method suitable for color temperature lamps, in particular to a PWM power adjustment method suitable for color temperature lamps. Background technique [0002] Color temperature lamps provide different color temperatures according to different ratios of warm light output power and cold light output power. In the prior art, with the development of the Internet of Things, there has been a variety of control chips to control warm light and cold light PWM output. Power intelligent color temperature adjustment lamp. However, most of the color temperature lamps in the prior art adopt a constant power PWM output power dimming method, resulting in that the output power of the same type of color temperature adjustment lamps cannot be fully utilized, which wastes efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PWM power adjustment method suitable ...
