Method for adjusting light of semiconductor lamp by adopting self-adaptive pulse-width modulation technology and lamp

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 lightingelement 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 assemb ly. 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 ...

However, there is a contradiction between long-term stable performance and cost of such lamps

The lighting of urban roads, especially the main roads, requires that the lamps can work stably for a long time. If the lighting lamps working on this occasion only use solar energy or wind energy as independent power sources, the cost of the lamps will be very expensive.
