A new LED backlighting advertising light box belongs to the field of advertising and propaganda, which is mainly suitable for high-speed railway platforms, bus platforms and other public places. Conventional advertising light box is basically a backlight illumination with a color temperature fixed separately, and is basically a conventional fluorescent lamp tube. As for the conventional backlighting advertising light box, it is difficult to give consideration to the color effect of different situations when changing the advertising cloth of different contents and highlighting the color effect of different advertising pictures. The utility model comprises four parts: an advertisement lamp box, a 6500K cold color temperature LED lamp bar, a 2700K warm color temperature LED lamp bar and a PWM power supply controller. The two different color temperature lamp bars are arranged side by side in the lamp box, and are independently controlled by different power supply circuits, so as to achieve the function of overall color temperature adjustment. As a new type of LED backlighting advertising light box, the utility model can not only adjust different color temperatures according to different advertising screen requirements to achieve the best advertising effect, but also has convenient operation and maintenance, and is easy to popularize and apply.
【技术实现步骤摘要】
一种新型的LED背光照明广告灯箱
本技术为一种新型的LED背光照明广告灯箱,属于广告宣传领域,主要适用于高铁站台、公交站台等公共场所。
技术介绍
目前,针对在高铁站、公交站台等场所LED背光照明的广告灯箱,其常规的LED背光照明模式如下:常规的LED背光照明,基本为一种色温的背光源,要么是暖色温的背光源,要么是冷色温的背光源,是目前最普遍一种背光照明模式。此种背光照明LED广告灯箱,虽然实现起来非常简单,但在更换不同内容的广告布、凸显不同广告画面颜色效果时,很难兼顾各种情况画面颜色的效果,;
技术实现思路
基于技术背景中所述的目前的技术现状,本技术提供了一种新型的LED背光照明广告灯箱,是集实现简单,且兼顾不同广告画面需求,对应调整不同的色温以达到最佳的广告展示效果相结合,是对LED背光照明广告灯箱性能的进一步提升。本技术,其特征在于包括广告灯箱、6500K冷色温LED灯条、2700K暖色温LED灯条、PWM电源控制器四个组成部分。进一步地,广告灯箱的左右两侧内壁,每侧内壁都同时安装6500K冷色温灯条与2700K暖色温灯条各一片。进一步地,左右两侧相同色温的灯条使用 ...
