Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0020] see Figure 1-4 ,本发明提供的一种实施例:一种屏幕亮度控制装置,包括控制箱1,控制箱1的上方设置有箱盖2,且箱盖2与控制箱1之间通过螺钉连接,箱盖2的上方设置有透光玻璃6,且透光玻璃6的一端贯穿箱盖2并延伸至箱盖2的下方,透光玻璃6便于屏幕图像传递,箱盖2的上方设置有电源开关4,电源开关4的一侧设置有调节旋钮3,且电源开关4和调节旋钮3的一端均延伸至箱盖2的内部,调节旋钮3可以调节滑动电阻RP接入电路的阻值,箱盖2的下方设置有LCD屏幕8,且LCD屏幕8与控制箱1的内壁贴合连接,LCD屏幕8的下方设置有电路板9,且电路板9与控制箱1通过螺钉连接,电路板9的下方设置有接线孔10,且接线孔10的一端贯穿控制箱1并延伸至控制箱1的外部,电路板9的两侧均设置有散热槽12,且散热槽12的一端贯穿控制箱1并延伸至控制箱1的外部,散热槽12可以将热量疏导出去,散热槽12的内部设置有散热风扇13,且散热风扇13与散热槽12通过螺钉连接。散热风扇13加快空气流动,加快热量疏导效率。

[0021] 进一步,控制箱1的内部设置有活性氧化铝垫11,且活性氧化铝垫11与控制箱1的内壁贴合连接。通过活性氧化铝垫11可以对控制箱1的潮湿气进行吸收。

[0022] 进一步,散热风扇13的一侧设置有防尘网14,且防尘网14与散热槽12的内壁贴合连接。通过防尘网14可以有效的避免外界灰尘进入到控制箱1的内部。

[0023] 进一步,透光玻璃6与箱盖2之间设置有密封条7,且密封条7分别与透光玻璃6和箱盖2贴合连接。通过密封...

Description

technical field [0001] 本发明涉及屏幕亮度技术领域,具体为一种屏幕亮度控制装置。 Background technique [0002] A screen, also called a display screen, is an electrical appliance used to display images and colors. 屏幕亮度是指发光物体表面发光强弱的物理量称为亮度,物理学上用L表示,单位为坎德拉每平方米或称尼特。 亮度是衡量显示器屏幕发光强度的重要指标,对于显示器面板来说,高亮度也意味着对其工作环境的抗干扰能力更高。 人们在看屏幕时,都希望亮度越高越好,这样画面更艳丽,细节表现更出色,但是过分追求亮度不但使耗电量增加,更容易引发眼睛疲劳,出现眼涩、眼皮沉重等症状,甚至导致视力下降和头痛等健康问题。 如何控制屏幕亮度这个问题越来越重要。 [0003] 目前,屏幕的亮度控制大多都是提高光线传感器来直接调节,他会对某个界限,当光线强度高于或低于这个界限时,就会对屏幕的亮度进行自我调节,可是在对一些视力不佳或色弱的使用者进行图像演示时,就会出现亮度过高引发眼睛疲劳或亮度过低图像观察不清晰,不能满足使用需求。因此市场上急需一种屏幕亮度控制装置来解决这人些问题。 Contents of the invention [0004] 本发明的目的在于提供一种屏幕亮度控制装置,以解决上述背景技术中提出屏幕亮度自我调节在对视力不佳或色弱的使用者使用时会带来不便,不能满足使用需求的问题。 [0005] 为实现上述目的,本发明提供如下技术方案:一种屏幕亮度控制装置,包括控制箱,所述控制箱的上方设置有箱盖,且箱盖与控制箱之间通过螺钉连接,所述箱盖的上方设置有透光玻璃,且透光玻璃的一端贯穿箱盖并延伸至箱盖的下方,所述箱盖的上方设置有电源开关,所述电源开关的一侧设置有调节旋钮,且电源开关和调节旋钮的一端均延伸至箱盖的内部,所述箱盖的下方设置有LCD屏幕,且LCD屏幕与控制箱的内壁贴合连接,所述LCD屏幕的下方设置有电路板,且电路板与控制箱通过螺钉连接,所述电路板的下方设置有接线孔,且接线孔的一端贯穿控制箱并延伸至控制箱的外部,所述电路板的两侧均设置有散热槽,且散热槽的一端贯穿控制箱并延伸至控制箱的外部,所述散...
