Description

[根据细则37.2由ISA制定的发明名称]　一种LED投影照明装置 技术领域
本发明是关于一种LED照明装置，特别是指一种用LED作为光源的移焦定焦投影照明装置。
背景技术
随着节能减排的发展趋势，LED（LightEmittingDiodes，发光二极管）以其节能环保、发光效率高、寿命长等特点，得到越来越广泛的应用，LED作为一种新型的固体光源，被应用于各种照明场所。
LED替代灯泡的照明装置已普遍应用于人们的日常生活中，为提高LED照明装置的功能性，本发明人的中国发明专利CN200610035815.9中揭示了一种LED的快速变焦照明装置，主要包括有一本体、一LED及一凸透镜；利用该LED相对该凸透镜的距离变化设为该凸透镜的零到两倍焦距范围内，只需调整LED相对凸透镜二者之间微距的快速变化而可快速改变光束角度，即可实现远距照明聚焦亮度强，近距离散光照明面积大的功能，调节速度快、操作迅速，以便于携带及应用于特殊场所，类似在枪上或自行车上使用的时候。
但是该LED照明装置仅具有照明的功能，如果在一些特殊场所需要求一些特殊的功能时，如发射警示或是求救信号时，单纯的闪烁已无法达到该功能需求，如何令该LED照明装置更直接的实现求救信号显示或具有影像形成的趣味性便是本发明需要解决的问题，以提高该LED照明装置的功能性，本案便由此产生。

所述图文薄膜或薄片相对该凸透镜的距离变化为该凸透镜的零到两倍焦距内清晰成像处。
所述图文薄膜或薄片在LED与凸透镜之间移动。
所述图文薄膜或薄片为连续切换的不同图文薄膜或薄片.
所述图文薄膜或薄片的图文为3D视觉图文。
所述本体上还设有一滑套，可前后自由滑动，凸透镜是设置在滑套上。
所述本体与滑套之间还设有一阻尼圈。
所述本体通过软管或万向接头支架连接在其它物体上。
所述本体设有快速螺纹，使该滑套螺接在该本体上。
采用是上述方案后，本发明通过在LED发光组件与凸透镜之间设置图文薄膜或薄片，且该凸透镜焦距可以相对LED光源移动，该凸透镜焦距也可以相对图文薄膜或薄片移动，且该凸透镜的焦距可以由LED成像移动到对图文薄膜或薄片的成像;该凸透镜焦距也可以由LED光源切换到图文薄膜或薄片，并该凸透镜的焦距可以由LED成像切换到对图文薄膜或薄片的成像，该图文薄膜或薄片相对该凸透镜的距离变化为该凸透镜的零到两倍焦距内清晰成像处。由此本发明在实现照明需求的同时，又切换至投射影像的功能，实现使焦距可在最大范围持续移动的移焦定焦照明功能和持续移动的移焦定焦投影功能产品的结合。
为使能更进一步了解本发明之特征及技术内容，请参阅以下有关本发明之详细说明与附图，然而所附图式仅提供参考与说明用，并非用来对本发明加以限制。

具体实施方式
配合图1至图10所示，本发明揭示的一种LED移焦定焦投影照明装置，包括本体1、电源装置、LED发光组件3及一凸透镜5；电源装置置于本体1中（如图中的电池），LED发光组件3设在本体1的前端，LED发光组件3通过电路板与电源装置形成电源联接，凸透镜5是设在该LED发光组件3前方的光轴上，二者可产生相对的前后移动，并且该LED发光组件3相对该凸透镜5的距离变化是凸透镜5的零至两倍焦距；
本发明的关键在于：在LED发光组件3与凸透镜5之间设有一透光的图文薄膜或薄片4，即该图文薄膜或薄片4是由透光的薄膜或薄片上印制图案、文字形成。
根据凸透镜的特性：
１、与主轴平行的光线，折射后通过另一侧的焦点。
２、通过透镜中心的光线，不折射而直进。
３、通过焦点的光线，折射后与主轴平行。
４、光线经凸透镜后会向内偏折而聚集。
５、凸透镜成像(f为焦距)：
若物在无穷远处，成一点在透镜另一边焦点上；
若物在2f之外，成缩小在透镜另一边f-2f处；
若物在2f之处，成相等在透镜另一边2f处；
若物在f-2f之间，成放大在透镜另一边2f之外；
若物在f上，无穷远处在透镜另一边；
若物在f-镜面之间，成放大在透镜同一边。
请参阅图1、图2A、2B，本发明LED移焦定焦投影照明装置的实施例一，主要包括一本体１、滑套2、一LED发光组件3、一图文薄膜或薄片4、一凸透镜５、一，该本体１之内部设有一电源装置，该滑套2装在本体１上，可前后自由滑动，或是在本体1设有快速螺纹，使该滑套2螺接在该本体上，同样实现前后移动；该本体１上设有一阻尼圈6，使该滑套2透过与阻尼圈6的磨擦力来定位。为使滑套2不从本体１上脱落，将固定座7螺接在本体１上，该固定座7之前端大于滑套2之后端内径，使该固定座7抵靠该滑套2。
当滑套透镜5与图文薄膜或薄片4平贴时，S1接近零时作为近处大范围照明，当滑套透镜5与LED发光组件3的距离S1是大于一倍时，S1在两倍焦距范围内,LED晶体成像在远处20m或更远，光线能量集中在远处，这时作为远处照明，另外根据照明远近及照亮范围的大小，可以无极的调节LED发光组件3和透镜5之间的距离，得到持续快速变化的照明光线要求，从而实现了本装置的照明作用。
另外本发明提供更大范围的移动距离，因为图文薄膜或薄片4设置在LED发光组件3的前方，当发光能量较强时，我们需要考虑图文薄膜或薄片4可能烧焦，LED发光组件3与图文薄膜或薄片4可能有凸透镜5一倍焦距，这样需要通过调节凸透镜5与图文薄膜或薄片4焦距S2将图文薄膜或薄片4的图文投影在前方，且图文薄膜或薄片4设置更接近凸透镜5,这样凸透镜5的移动距离就需要非常大，图文可以是3D视觉投影，把图文膜做成丰富的图片，通过持续的移动透镜，把图文膜上的图片透过连续(无段)的移动，出现生动的图片变化，增加趣味性并有广告效应，亦或形成'SOS'字样以实现求救信号的作用。
请参阅图3，本发明实施例二，主要同实施例一，增加一个图文薄膜或薄片4的固定结构，该固定结构为一固定环41，其为一个环状固定圈,配有螺纹或卡钩，使薄膜或薄片4可以夹在41与本体1之间,随时按需要更换图文内容,这样可以直接把照片等图文片用在本装置上,可以是名人图、卡通图、节庆日标志等图片。
请参阅图4，本发明的实施例三，图文薄膜或薄片4可以用不同内容ILOVEYOU、HEART、STOP、NOSMOKING，TOILET、MAN、WOMAN等等进行切换，类似这些文字内容的图文薄膜或薄片4固定在一个可以旋转的支架12上,通过旋转图文薄膜或薄片4的支架12,改变投影内容,连续的移动滑套2上的透镜5与本体1之间距离,可以让图片大小变化，可以是投影内容的变化，内容的变化例如可以由MAN变为WOMAN,再变TOILET,按照设计者或用户的需要制定不同图文内容及投影次序。
请参阅图5，本发明的实施例四，在本装置的尾部或中部等不同的位置设置不同的固定结构，使得本装置可以安装在不同场合使用，可以是通过软管10悬挂固定，或装在万向支架固定,可以作为轨道灯等使用。
请参阅图6、7，本发明的实施例五,本装置设置在象鼻灯内使用,主要包括一象鼻灯本体13、滑套2、固定筒1，LED发光组件3、一图文薄膜或薄片4、一凸透镜５，该象鼻灯本体13之内部设有一电源装置，该滑套2在固定筒1上，可前后自由滑动,滑套2上设置一阻尼圈6,使该滑套2透过与阻尼圈6的磨擦力来定位,该滑套2后端大于固定筒1之前端内径，使该滑套2抵靠固定筒1，不会滑落。
请参阅图8，本发明的实施例六，为了完成更加复杂的系统的组合，可以做成多头装置，每单个装置可以指向不同位置，可以做不同组合，可以不同投影（不同图片）和不同照明要求（光斑大小和远近照明不同），完成多角度多方向的移焦定焦投影系统.
请参阅图9，本发明的实施例七，所述的固定装置是在实施例一的滑套上增加一螺丝孔(图中无标示)，一固定螺丝14，固定装置滑套上增加了螺丝14；当滑套移动到特定位置时，锁紧滑套上的螺丝,滑套与本体之间无法移动,锁定在特定的光束角度，照射特定的范围。

综上所述，本发明通过在LED发光组件3与凸透镜5之间设置图文薄膜或薄片4，且该凸透镜5焦距可以相对LED光源3移动，该凸透镜3焦距也可以相对图文薄膜或薄片4移动，且该凸透镜3的焦距可以由LED成像移动到对图文薄膜或薄片4的成像;该凸透镜5焦距也可以由LED光源切换到图文薄膜或薄片，并该凸透镜5的焦距可以由LED成像切换到对图文薄膜或薄片4的成像，该图文薄膜或薄片4相对该凸透镜5的距离变化为该凸透镜5的零到两倍焦距内清晰成像处。
由此可见，本发明揭示的LED快速变集照明装置，其在实现照明需求的同时，又切换至投射影像的功能，本发明使焦距可在最大范围持续移动的移焦定焦照明功能和持续移动的移焦定焦投影功能产品的结合，且相对习知的投影装置具有突破性的改变，因习知的投影装置，包括外壳、电池、按钮和发光管，所述电池、按钮和发光管构成回路且依次设置在外壳内的后部，按钮设在外壳的侧壁上；此外还包括安装筒、投影镜片和具有图文的薄膜，所述安装筒活动连接在外壳的前端，投影镜片固定在安装筒的前部；所述具有图文的薄膜设置在发光管和投影镜片之间。该投影装置功能单一，最多只能作为辅助照明使用，且投影的功能单一，缺少丰富变化。
