Combined energy-saving street lamp and energy-saving control method thereof

Abstract

The invention relates to the technical field of illumination, and particularly to a combined energy saving street lamp and an energy-saving control method thereof. The combined energy-saving street lamp comprises the components of: a high pressure sodium lamp module or xenon lamp module, and an LED lamp module. The combined energy saving street lamp further comprises the components of: a controller module; an optical sensing module which is used for sensing brightness around the street lamp environment and feeding a signal value to the controller module; and an illuminating clock control module, wherein the controller module is electrically connected with the optical sensing module and the illuminating clock control module. The power of the high pressure sodium lamp module or the xenon lamp module is a standard power of the street lamp. The power of the LED lamp module is smaller than the standard power of the street lamp. The invention further provides a control method in a targeted manner. According to the technical solution of the combined energy saving street lamp, through combination of the LED lamp and the high pressure sodium lamp or the xenon lamp, the advantages of the two lamps are sufficiently utilized, thereby settling a problem of high difficulty in brightness adjustment when the high pressure sodium lamp or xenon lamp is used as the street lamp.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a combined energy-saving street lamp and an energy-saving control method thereof. Background technique [0002] With the rapid development of urban modernization, there will be more and more demands for traffic roads and urban public lighting. Therefore, how to effectively control the energy saving of these street lights is a problem that must be faced in the modernization of each city. [0003] Energy saving of street lamps includes two methods: improving the conversion rate of light-emitting modules and adjusting the brightness of street lamps according to needs; the existing street lamp lighting modules use one of high-pressure sodium lamps, xenon lamps or LED lamps, and the configuration and maintenance costs of LED lamps are relatively high. ; High-pressure sodium lamps and xenon lamps have the characteristics of high conversion efficiency and low configuration and maintena...
