Description

发光二极管灯具

技术领域

[0001] 本发明涉及一种灯具,特别是指一种发光二极管灯具。 背景技术

[0002] 作为一种新兴的光源,发光二极管凭借其发光效率高、体积小、重量轻、环保等优 点,已被广泛地应用到当前的各个领域当中,大有取代传统光源的趋势。

[0003] 某些环境较为复杂的场所(例如户外及湿度大或粉尘严重的区域)对于灯具的防 护性有一定的规定,要求所使用的灯具具有相应的防尘防水等级,以保证灯具在恶劣的环 境下仍可以正常的使用。另外,发光二极管有别于其它光源,其特性决定了它的使用环境要 求比传统的光源更为严格。因此,如何提升发光二极管灯具的防护等级,使之能在较为恶劣 的环境中使用,乃当前尚待解决的技术问题。

发明内容

[0004] 本发明旨在提供一种可在恶劣条件下使用的发光二极管灯具。

[0005] 一种发光二极管灯具,包括一灯头、一连接灯头的灯壳、收容于灯壳内的发光二极 管模组及一连接灯壳并盖住发光二极管模组的透光灯罩,灯壳与透光灯罩之间以及灯壳与 灯头之间均为密封连接,从而形成一容置发光二极管模组的密闭腔室。

[0006] 与现有技术相比,本发明的发光二极管灯具在其灯头与灯壳之间以及灯壳与灯罩 之间均采用密封连接,可确保收容在灯壳内的发光二极管与外界环境隔绝。因此,本发明的 发光二极管灯具防护等级较高,可适应多种恶劣环境的需求。

[0007] 下面参照附图,结合具体实施例对本发明作进一步的描述。

具体实施方式

[0015] 请参阅图1及图2,示出了本发明的发光二极管灯具。该发光二极管灯具包括一灯 头10、一与灯头10连接的灯壳20、一收容于灯壳20内的发光二极管模组30、一盖住发光二 极管模组30的透光灯罩40及一将灯罩40固定于灯壳上20的压圈50。

[0016] 该灯头10包括一灯帽12及一连接至灯帽12顶部的灯颈14。该灯帽12为一标准 的E27金属灯帽,其可与现有的通用灯具接口匹配连接,以为发光二极管模组30提供电流。 该灯颈14呈一中空的漏斗形,其较小的一端用于插入灯帽12顶部以将灯颈14固定于灯帽 12上,其较大的一端向内凸伸有三凸肋140,以供螺杆60锁入。

[0017] 请一并参阅图34,该灯壳20由金属材料一体成型,其包括一筒体22及若干自筒体 22外周面辐射出的鳍片M。该筒体22为中空状,其底部至中部的口径为一恒量,其中部至 顶部的口径随着高度的增加而渐增。一隔板沈形成于筒体22中部以将筒体22内部分隔 为上下两个内腔220、222。该筒体22的底部开设一与下内腔222连通的环形凹槽224(如 图3),用于收容一垫圈70。该筒体22的底部的剩余部分抵接于灯颈14的顶面,从而将垫 圈70夹置在二者之间,以对灯壳20与灯头10间进行密封。该筒体22在其下腔体222的 内周面上分别向内凸伸出连接隔板沈底部的三凸块观,这些凸块观与灯颈14的凸肋140 相互对齐,以供螺杆60穿过。一驱动模组80收容于筒体22的下内腔222中,用于对灯帽 12输入的电流进行调节并将调节后的电流输入给发光二极管模组30。该驱动模组80在其 基板(未标号)的周缘开设有与灯颈14的三凸肋140对应的三缺口(未标号)。该隔板 26用于承载发光二极管模组30,并同时将发光二极管模组30工作所产生的热量通过筒体 22传输到鳍片M上。三螺杆60依次穿过灯壳20的隔板沈及三凸块观并最终锁入灯颈 14的三凸肋140内,从而将灯壳20固定于灯颈14上。筒体22的顶部开设一与上内腔220 隔开的环形凹槽226,用于收容另一垫圈72。这些鳍片M均布于筒体22的外周面上,以将 热量快速地散发至空气中。四矩形凸台四自筒体22的外周面水平向外凸出,每一凸台四 连接二相邻鳍片M的顶部并与筒体22的顶部齐平。这些凸台四用于给螺丝62提供支撑 作用,使其能稳固地穿设在灯壳20上。隔板沈还开设有导线穿孔(图未示),以供连接该 驱动模组80及发光二极管模组30的导线穿过。

[0018] 该发光二极管模组30包括一电路板32、若干固定于电路板32上的发光二极管34 及若干分别包覆这些发光二极管34并装设于电路板32上的透镜36。该电路板32通过螺 丝64锁固于灯壳20的隔板沈上,以将整个发光二极管模组30收容于筒体22的上内腔 220 中。

[0019] 该灯罩40呈圆形,其由透光材料所制成。该灯罩40的外径大于凹槽226的外径 并小于灯壳20的外径。灯罩40被压圈50抵压在灯壳20顶部而与筒体22共同挤压另一 垫圈72,由此,灯罩40与灯壳20之间亦被密封起来,以将灯壳20上内腔220与外界环境隔绝。

[0020] 该压圈50由二内外同心环52、56及四连接该二同心环52、56的凸起M所构成。 外同心环56的高度与凸起M的高度相等并大于内同心环52的高度。该四凸起M分别与 灯壳20的四凸台四对齐,其用于供穿过灯壳20凸台四的螺丝62锁入,从而将压圈50固 定在灯壳20顶部。该内同心环52通过一缓冲垫90抵压灯罩40的周缘,以将灯罩40固定 于压圈50及灯壳20之间。该缓冲垫90呈环形,其用于对灯罩40起一缓冲作用,以防止压 圈50的压力过大而造成灯罩40损坏。

[0021] 由于本发明的灯具在与形成上下内腔220、222有直接关联的各个分离的部件之 间(即灯壳20与灯罩40之间以及灯壳20与灯头10之间)都设有垫圈70、72,收容于灯 壳20中的发光二极管模组30可被很好地与外界隔绝开,从而有效防止外界的水汽或者粉 尘进入灯具内。因此,本发明的发光二极管灯具的防护等级较高,可适应多种恶劣环境的特 殊需求。

[0022] 此外,由于采用了标准灯帽12,本发明的发光二极管灯具可与目前通用的灯具接 口连接,应用范围较广。

[0023] 并且,由于驱动模组80被隔设于下内腔222中,其工作时产生的热量可被隔板沈 所阻挡而不会直接散发至上内腔220中以致于影响发光二极管模组30的工作温度,因此, 通过将发光二极管模组30与驱动模组80分隔设置,可有效地避免驱动模组80散发的热量 对发光二极管模组30的干扰,以确保发光二极管模组30的正常运作。
