Technical Problem

[0002]在现有光源类产品中,如BR灯(英文全称为Bulged Reflector Bulb,中文名为抛物面反射灯)、A泡(英文全称为A-series light bulb,中文名为A系列灯泡,也常被称为梨形灯泡或标准灯泡)、G泡(英文全称为Globe Shape Bulb,中文名为G系列灯泡,也叫球形灯泡),虽有部分现有技术公开了针对主光源设置两层罩的技术方案(例如申请号为“CN221035426U”,专利名称为“一种带小夜灯功能的LED灯”的专利),或单独为光源产品增设背光源的技术方案(例如申请号为“CN213656561U”,专利名称为“灯具”的专利),但这些技术仍存在功能局限,无法满足多样化照明需求

Benefits of technology

本方案以散热器为载体,在其向外扩散罩的一端面上设置主光源组件,实现传统光源的正面常规照明功能;同时在散热器背离外扩散罩的一端面上设置背光源组件,并配合有色的内扩散罩和透明的塑壳,背光源组件的发光方向是朝向内扩散罩,而非直接照射用户活动区域,能够避免强光直射,透明的塑壳可让经内扩散罩处理后的柔和光线顺利透出,从灯体背面及侧面形成“环绕式”的柔和光照,这种光照形式更适配夜灯“低范围、局部照明”(如床头夜灯仅需照亮床周区域)和氛围照明“大面积、衬托式照明”(如客厅灯背面光线照亮墙面,形成间接氛围光)的需求,从而能够实现常规照明与柔和氛围照明的双重功能;本方案中的内扩散罩设置在塑壳内部,一方面可遮挡主光源组件、背光源组件、散热器及内部电子元器件,避免外部看到杂乱器件;另一方面能对背光源组件光线进行扩散柔化,确保夜灯/氛围照明光线的柔和度;同时透明的塑壳替代传统不透光的塑壳,为经内扩散罩处理后的背光源光线提供有效射出通道,避免传统塑壳阻挡光线导致背光源功能失效,确保夜灯/氛围照明功能切实可用。

Abstract

The utility model relates to lighting equipment technical field, especially light source structure, including outer diffusion cover, transparent plastic shell and coloured inner diffusion cover, the plastic shell has first opening, the inner diffusion cover has and the second opening of first opening consistent orientation, the plastic shell is set in the inner diffusion cover outside, the outer diffusion cover cover is established at first opening department, the inner diffusion cover inside is equipped with radiator, to radiator as carrier, on its one end surface of outer diffusion cover sets up main light source assembly, realizes the front conventional lighting function of traditional light source, while setting up backlight source assembly on the one end surface of radiator away from outer diffusion cover, and cooperate coloured inner diffusion cover and transparent plastic shell, the light emitting direction of backlight source assembly is towards the inner diffusion cover, and not direct illumination user activity area, can avoid strong light direct illumination, the transparent plastic shell can let the soft light after the treatment of inner diffusion cover smoothly penetrate, thereby can realize the dual function of conventional lighting and soft atmosphere illumination.
