柔性 LED灯具及其制造方法
技术领域
本发明涉及照明领域, 特别是一柔性 LED 灯具及其制造方法, 所述柔性 LED灯具相较现有传统 LED灯具具有更优良的使用性能, 从而可被更好地应用 于生活应用中。 背景技术
LED灯具有节能、 环保、 安全、 高寿命、 体积小、 亮度高等优势, 正是这 些不可比拟的优势使得 LED灯正在全面取代普通日光灯, 而被应用在生活的各 个领域。 不仅如此, 现有的 LED灯还通过配光技术已从原初的点光源灯被扩展 为面光源灯的模式, 使得 LED面光源灯具有更大更亮的发光面, 可创造更好的 视觉效果, 以为使用者提供更佳的视觉体验, 故 LED灯经常被应用于各种场景 及环境的灯光布置当中。
特别是近些年来, 随着人们对精神文化以及娱乐生活的追求, 摄影摄像直播 娱乐等行业不断兴起。 比如电视上的各种娱乐节目, 互联网上层出不穷的直播平 台等的出现不断地丰富了人们的业余生活, 但与此同时, 这也对这些摄像摄影平 台的成品质量提出了更高的要求。在其中, 灯光布置以及灯光效果对摄像摄影最 终成品具有显而易见的影响, 换言之, 在摄影摄像平台领域当中, 灯光布置是一 件不容忽视的事情。 然而在现有的灯光布置领域当中, LED灯由于其安全、 体 积小、耗能低等优点被广泛应用于影视灯具及摄像灯具当中, 因此也被更加广泛 地被应用于演播室、 室内外影视视频拍摄、 室内外摄影拍照等的灯光布置当中。
但在实际的摄像灯光布置当中,不仅仅需要对布置灯光本身的发光性能提出 很高的要求, 更需要布置灯光能够适应各种复杂多变的摄影摄像环境。 就比如, 在拍摄电影电视剧的过程中,导演就常常需要根据不同的电影主题思想等主观因 素调整光源的角度位置及色温等;再比如,在室外影像视频照片拍摄的过程当中, 摄像人员需要针对不同的地理环境等客观因素及时地调整布置灯光;或者在室内 节目录制过程当中, 灯光师需要根据场景变化调整灯光以创造更好的舞美效果。 这些情况都对灯光布置提出了更高的要求, 然而传统的 LED灯过于笨重, 而很 难满足高要求的灯光布置的需求。其主要原因归结于传统的 LED灯本身的散热, 结构保护, 面光源排布的设计, 使得传统的 LED灯存在厚重、 不易携带等缺陷。
鉴于以上情况, LED柔性灯板的面世初步解决了传统 LED灯笨重的问题。 换言之, LED柔性灯板相较传统的 LED灯具有轻薄柔韧的优点,但也正由于 LED 柔性灯板变得更加轻薄柔韧, 从而牺牲了 LED柔性灯板的结构强度。在 LED柔 性灯板的实际应用当中, 由于其上的 LED灯珠很脆很薄, 往往容易因弯折或触 碰而破损或脱焊, 而导致 LED柔性灯板的面光源存在坏点而不便再次使用。 此 外, 为了使得所述 LED柔性灯板可应用复杂的环境中, 所述 LED柔性灯板往往 还需要采用防水的多层密封设计。
如图 1所示, 图 1展示了现有技术中的 LED柔性灯板的结构。所述 LED柔 性灯板包括一电路板 1P, 一系列排布在所述电路板 1P上的 LED灯珠 2P, 以及 一覆盖在所述电路板 1P上的防水层 3P。 其中, 所述 LED灯珠 2P电连接于所述 电路板 1P, 以实现所述 LED灯珠 2P的发光发亮。 其中所述电路板 1P被实施为 柔性电路板, 以使得所述 LED柔性灯板具有更优良的柔韧性。 所述 LED灯珠 2P电连接并且排布在所述电路板 1P上, 以构成所述正常 LED柔性灯板。 然而 为了使得所述 LED柔性灯板能够更好地应用于复杂环境当中,所述 LED柔性灯 板还包括所述防水层 3P,其中所述防水层 3P覆盖在所述电路板 1P以及所述 LED 灯珠 2P上, 以防止外界水分进入所述电路板 1P损坏所述 LED柔性灯板的正常 使用。然而在实际生产或者使用过程当中,所述防水层 3P与所述电路板 1P之间 容易产生封闭的气泡,所述气泡在使用过程中会由于所述 LED灯珠 2P的发热而 膨胀, 甚至爆破, 进而损坏所述 LED柔性灯板的正常使用。 换言之, 所述 LED 柔性灯板的防水性在实际应用中依旧表现的不良好。
综上所述, LED灯具, 特别是应用于灯光布置的 LED灯具需要满足柔软, 防水、 稳定性高以及不易损坏等优点, 以更好地被应用各种生活领域当中, 然而 现有的 LED灯具依旧不能同时满足以上优点, 存在很大的改善空间。 发明内容

其中所述 LED灯珠 21可被实施为普通 LED灯, 双色温 LED灯, 甚至多色 温 LED灯。在本发明的实施例当中,所述 LED灯珠 21被实施为双色温 LED灯, 但熟悉该项技术的人应该明白, 所述 LED灯珠 21的类型并不受限制。
如图 4所示, 当所述 LED灯珠 21被实施为双色温 LED灯时, 所述 LED灯 珠 21包括至少一一号灯珠 211, 以及至少一一二号灯珠 212, 其中所述一号灯珠 211以及所述二号灯珠 212独立设置于所述 LED灯珠 21中并且共同发射不同色 温的光 。
优选地, 所述一号灯珠 211以及所述二号灯珠 212中可分别被实施为正白灯 珠以及暖白灯珠。其中可选择为所述一号灯珠 211被实施为正白灯珠, 所述二号 灯珠 212被实施为暖白灯珠。也可选择为是所述一号灯珠 211被实施为暖白灯珠, 所述二号灯珠 212被实施为正白灯珠。本发明在这方面不做限制。 当然, 本发明 所提及的正白灯珠也可被实施为多组正白灯珠的组合,所提及的暖白灯珠也可被 实施为多组暖白灯珠的组合。
以下将以所述一号灯珠 211被实施为正白灯珠, 所述二号灯珠 212被实施为 暖白灯珠的所述 LED灯珠 21为例进行说明, 但不作为限制。 一般而言, 所述正 白灯珠泛指发光色温高于 5000K的灯珠,所述暖白灯珠泛指发光色温低于 5000K 的灯珠, 当所述 LED灯珠 21被实施为双色温灯珠时, 所述一号灯珠 211以及所 述二号灯珠 212发出的光亮可互补光效, 以获得成效效果更加柔和, 白平衡更加 准确的出射光线。
