Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] attached figure 1 According to the present invention, the intelligent lighting control method for dynamically adjusting LED street lamps based on environmental changes of the present invention includes the following steps:

[0020] S1: The user sets the corresponding setting value Cs(n) of lighting color temperature under different time and seasons, the corresponding setting value Is(x) of illuminance under different environmental parameters, the color temperature value Cp(c) corresponding to different particle concentrations, and different The color temperature value Cr(w) corresponding to the amount of rain;

[0021] S2: Read the current time, determine the current time season T(s), and compare the lighting color temperature settings in different seasons to determine the Cs(n) value of the LED lighting corresponding to the sea...

Abstract

The invention discloses a control method for dynamically adjusting intelligent illumination of an LED street lamp based on environmental change. The control method comprises the following steps: (1) a user setting an illumination color temperature corresponding set value Cs(n) under different time and seasons, an illumination corresponding set value Is(x) under different environmental parameters, a color temperature value Cp(c) corresponding to different particulate matter concentrations and a color temperature value Cr(w) corresponding to different rainwater amounts; (2) determining the Cs(n) value of LED illumination in corresponding season; (3) determining an LED street lamp illumination working value I(o) corresponding to the environmental illumination, wherein I(o) is equal to Is(x); (4) determining the color temperature value Cp(c) corresponding to the current particulate matter concentration; (5) determining the color temperature value Cp(c) corresponding to the current rainwater amount; (6) taking the average value of the determined Cs(n), Cp(c) and Cp(c) as a working control color temperature value C(o), wherein C(o) is equal to [Cs(n)+Cp(c)+Cp(c)] / 3; and (7) according to the values of I(o) and C(o), determining the duty ratio of each PWM control signal to output control signals. According to the control method, good controllability of LED illumination can be sufficiently played, and an optimal illumination effect can be reached at any time.

Description

technical field [0001] The invention relates to an improvement of a lighting controller method for LED street lamps, in particular to an intelligent lighting control method for dynamically adjusting LED street lamps based on environmental changes that can give full play to the greatest advantages of LED lighting and achieve the best lighting application effects. Background technique [0002] LED lighting has been widely used in functional outdoor lighting occasions such as roads. The existing LED lighting mainly includes two modes: constant power lighting without dimming and variable power with dimming. Most of the occasions use white light lighting. . Compared with traditional sodium lamp lighting, it has the advantages of energy saving and good dimmability. The current lighting method using a single white light cannot well change the lighting effect according to seasonal weather, environmental factors, etc., and it is difficult to give full play to the maximum advantages ...
