Embodiment Construction

[0032] A method for dimming lamps using adaptive pulse width modulation technology:

[0033] a. Using time-people and vehicle flow optimization control, the clock module generates a reference clock signal, which is sent to the port of the computer module, and the built-in computer determines the corresponding time according to the time-people and vehicle flow statistics of pedestrians and vehicles on urban roads. The time-illuminance adjustment rate is built into the built-in computer, and then according to the time-illuminance adjustment rate, the pulse width modulation signal is output from the adaptive pulse width modulation terminal to drive the intelligent power switch device and control the luminous intensity of the light-emitting element to achieve the actual illuminance best match for

[0034] b. Adaptive pulse width modulation technology dimming method is adopted. The photoelectric sensor outputs the corresponding voltage according to the ambient light level, and send...

Abstract

The invention relates to a method for adjusting the light of a semiconductor lamp by adopting a self-adaptive pulse-width modulation technology and a lamp. The method adopts optimal control of time, people and vehicle flow rate and environmental lighting degree and outputs pulse-width modulation signals from a self-adaptive pulse-width modulation end to control the lighting intensity of a lighting element so as to achieve the optimal match of the actual lighting degree. The lamp consists of a lamp body assembly, a bracket, the lighting element, a transparent lampshade and a lamp circuit assembly. The bracket is fixed in the lamp body assembly, the lighting element is arranged on the bracket, the lamp circuit assembly is arranged in the lamp body assembly and the transparent lampshade is arranged on the lamp body assembly. The lighting element consists of a semiconductor high brightness LED, a radiator and a temperature sensor. The lamp circuit assembly consists of a power supply module, a power supply switch-protection module, a power control module, a lighting module, a computer module U6, a sensor module, a clock module and a wireless date transmission module U5.

Description

technical field [0001] The invention relates to a method for dimming an illumination lamp and a lamp, in particular to a method for dimming a lamp by adopting an adaptive pulse width modulation technology and the lamp. Background technique [0002] At present, in my country's lighting power consumption, urban public lighting accounts for 30% of the proportion. The construction of night scene lighting has become an important part of the construction of urban municipal facilities. According to the requirements of the Ministry of Construction, the lighting rate of large cities should reach 97%, and that of small and medium-sized cities should reach 95%; the lighting rate of urban roads should reach 100%, and the lighting rate of public areas should reach 95%; Design standard value requirements. Therefore, the energy saving of urban lighting fixtures is of great significance. In most cities in our country, during the period from 12:00 midnight to 6:00 am when the night scene ...
