Description
本發明是有關於一種燈具,且特別是有關於一種設置於一物體表面的燈具。 The present invention relates to a lamp, and in particular to a lamp arranged on the surface of an object.
設置於物體表面的燈具,應用光線投射在需要展現光影變化的物體表面(例如:天花板、牆壁、舞台背景、展覽品)上,可產生明暗不同之各種光影變化。以設置於牆面的小夜燈為例,由於所發出的一部分光線會先投射到牆面上再向外出射,可提供低亮度的昏弱光線,以避免刺激眼睛而干擾使用者的睡眠,同時又能提供臨時性小範圍的夜間照明。 Lamps installed on the surface of objects use light to project on the surface of objects that need to show changes in light and shadow (such as ceilings, walls, stage backgrounds, exhibits), which can produce various light and shadow changes with different light and shade. Take a night light installed on the wall as an example. Since part of the light emitted will be projected onto the wall first and then emitted outward, it can provide low-brightness dim light to avoid irritating the eyes and disturbing the user's sleep. At the same time, It can also provide temporary small-scale night lighting.
然而,目前小夜燈之燈泡大多設於燈罩中,使燈泡直接由燈罩中心朝外(牆面)發光,以致光線之照明亮度不均,光線容易刺眼,無法充分符合消費市場之需求。因此要如何改善上述問題與缺失,即為相關產業暨廠商所極力研究發展之方向。 However, most of the current night light bulbs are installed in the lampshade, so that the bulb emits light directly from the center of the lampshade toward the outside (the wall). As a result, the illumination brightness of the light is uneven and the light is easily dazzling, which cannot fully meet the needs of the consumer market. Therefore, how to improve the above problems and deficiencies is the research and development direction that related industries and manufacturers are striving to research and develop.
本說明書的實施例揭示一種燈具,設置於一牆面,包括:殼體、第一反射片以及光源。殼體具有一個底部、一個開 口以及一個內壁,內壁連接底部和開口,藉以定義出一個空腔,開口面對牆面。第一反射片位於內壁上具有第一反射面。光源位於空腔之中,用以提供至少一個光束,經由第一反射面反射後由開口向牆面射出。 The embodiment of this specification discloses a lamp, which is installed on a wall and includes: a housing, a first reflective sheet and a light source. The shell has a bottom, an opening The opening and an inner wall connect the bottom and the opening to define a cavity, with the opening facing the wall. The first reflective sheet is located on the inner wall and has a first reflective surface. The light source is located in the cavity and is used to provide at least one light beam, which is reflected by the first reflective surface and then emitted from the opening toward the wall.
根據上述實施例,本說明書是提供一種設置於牆面的燈具,其包括一個開口面對牆面的殼體、至少一個位於殼體中的光源以及至少一個位於殼體內壁上的反射片,用以將光源所提供的光束經由反射片進行至少一次反射之後,再由開口向牆面射出,藉以增加光束在殼體內部進行混光的機率,提高出射光的均勻度。 According to the above embodiments, this specification provides a lamp installed on a wall, which includes a housing with an opening facing the wall, at least one light source located in the housing, and at least one reflective sheet located on the inner wall of the housing. After the light beam provided by the light source is reflected at least once by the reflective sheet, it is then emitted from the opening to the wall, thereby increasing the probability of the light beam being mixed inside the housing and improving the uniformity of the emitted light.

請參照第1A圖和第1B圖,第1A圖係根據本說明書的一實施例所繪示的燈具100部分結構剖視圖;第1B圖係繪示第1A圖的燈具100部分剖面結構放大圖。其中,燈具100包括:殼體101、固定座102、透光燈罩103、第一反射片104以及光源105。如第1A圖所繪示,殼體101與固定座102連接,並通過固定座102固定於牆面11上;殼體
101具有一空腔101s,第一反射片104以及光源105設於空腔101s之中;透光燈罩103設於殼體101上。另外,在本說明書的一些實施例中,燈具100還可以包括至少一個裝飾件106(例如飾板或飾殼),固定於殼體101底部101a和內壁101b的外側。
Please refer to Figures 1A and 1B. Figure 1A is a partial structural cross-sectional view of the
在本說明書的一些實施例中,殼體101可以是一種由不透光材質(例如,金屬)或半透光材質(例如塑化材質)所構成。其中,殼體101包括一個底部101a以及至少一個與底部101a連接的內壁101b和一個與底部101a連接的結合套筒101c,用以定義出空腔101s。結合套筒101c的中心軸H,可以與空腔101s的開口101o的中軸線101d平行。
In some embodiments of this specification, the
在本實施例中,結合套筒101c可以是由底部101a向上延伸的一個(或多個立壁組成的)環狀立壁所構成的套筒狀結構,可用於承載光源105和透光罩103,並且將殼體101與固定座102結合。其中,結合套筒101c的環狀立壁可以與殼體101的內壁101b共同定義出一個環狀空腔101s。結合套筒101c的中心軸H與空腔101s的開口101o的中軸線101d共軸。
In this embodiment, the
固定座102包括一個卡合部102a和一個固定部102b。其中,卡合部102a設於結合套筒101c之中(位於環狀立壁的相反一側),固定部102b位於結合套筒101c外側,與卡合部102a沿著結合套筒101c的中心軸H向外延伸至結合套筒101c外側的一端(未繪示)結合,藉以將結合套筒101c卡合在卡合部102a和固定部102b之間。固定部102b的未與卡合部102a連接的另一端,則再沿著結合套筒101c的中心軸H
向外延伸至空腔101s開口101o的外側,並固定於牆面11上,藉以使空腔101s的開口101o面對牆面11。
The fixed
光源105固定於殼體101的空腔101s之中。例如在本說明書的一些實施例中,光源105可以包括複數個發光單元105a,例如複數個發光二極體晶粒(或燈珠),固定於結合套筒101c的環狀立壁上。光源105可以包括一個圓環形燈板(燈座)105b,燈板(燈座)105b的中心開口105o套設於結合套筒101c的套筒狀結構上,且燈板(燈座)105b沿圓周方向的外側表面與殼體101的底部101a夾一個銳角α1或一直角。多個發光單元105a則設於環形燈板105b沿圓周方向的外側表面。
The
例如在本實施例中,多個發光單元105a所組成的環形燈條,環形排列在環形燈板105b的外側表面。當發光單元105a發光時,每一個發光單元105a投射的平行光束,可以混合產生環形的均勻柔和的非指向性光源,避免產生刺眼的光線干擾使用者的睡眠。
For example, in this embodiment, a ring-shaped light bar composed of a plurality of light-emitting
透光燈罩103也通過結合套筒101c固定於殼體101的空腔101s之中。在本實施例中,透光燈罩103包括一個襯套103a、一個上蓋套筒103b和一個透光蓋板103c。襯套103a套設並固定於結合套筒101c的套筒狀結構上方;上蓋套筒103b套設並固定於襯套103a,透光蓋板103c由上蓋套筒103b的下緣往殼體101的底部101a延伸,形成一個環形透光殼體,覆蓋於光源105的環形燈條上。
The
在本實施例中,由於透光蓋板103c的下緣低於環形燈條的最低點,可使透光蓋板103c置於殼體101的內壁101b和每一個發光單元105a之間,藉以達到讓使用者從殼體101空腔101s的開口101o處向內看不到發光單元105a(燈珠)的目的。
In this embodiment, since the lower edge of the light-transmitting
在本說明書的一些實施例中,透光燈罩103可以是一種由透光或半透光之塑化材料(例如樹脂)所構成的殼體結構。襯套103a和上蓋套筒103b的透光度可以小於透光蓋板103c的透光度。且透光蓋板103c上可以另外添加(或塗佈)擴散劑,或在其表面形成凹凸起伏的微結構,用以增加透光蓋板103c的導光和/或擴散等光學效果,進一步提升燈具100往牆面11方向投射之光線的照度和均勻度。
In some embodiments of this specification, the light-transmitting
例如,透光蓋板103c中所使用的擴散劑成分可以包括:有機矽光擴散劑和/或無機光擴散。其中,所述的有機矽光擴散劑可以例如是(但不以此為限),壓克力型、苯乙烯型、丙烯酸樹脂型等其中之至少一者。所述的無機光擴散可以例如是(但不以此為限),硫酸鋇、碳酸鈣、二氧化矽等其中之至少一者。
For example, the diffusing agent component used in the light-transmitting
值得注意的是,為了避免透光燈罩103的材質,因長期受光源105的照射或高溫影響而劣化。在本說明書的一些實施例中,透光蓋板103c與每一個發光單元105a之間的距離K需要維持大於9(毫米)mm。另外,透光蓋板103c中的擴散劑含量可以控制在透光燈罩103整體重量的0.1%至5%之間。
It is worth noting that in order to prevent the material of the
第一反射片104固定於殼體101的內壁101b上,並具有一個第一反射面104a對應於(例如,面對)光源105的發光單元
105a。在本說明書的一些實施例中,第一反射片104可以是一種金屬板材或其他可反射光線之材料所構成的板材、片材或塊材。例如在本實施例中,第一反射片104可以是一種共形毯覆(Conformally covering)於殼體101的內壁101b上的金屬膜片,第一反射片104的第一反射面104a與殼體101的底部101a形成一鈍角θ,並延伸覆蓋於與殼體101的底部101a上。
The first
由光源105所提供的光束,可以在穿過透光燈罩103之後到達第一反射面104a,經由第一反射面104a至少一次的反射後,再由殼體101的開口101o向牆面11射出。例如在本實施例中,由光源105所提供的一部分光束L1,可在穿過透光蓋板103c之後,直接投射至牆面11。由光源105所提供的另一部分光束L2,在穿過透光蓋板103c之後,經過第一反射片104的一次反射後,再投射至牆面11。由光源105所提供的又一部分光束L3,可在穿過透光蓋板103c之後,經過第一反射片104的二次反射後再投射至牆面11。季由將投射至牆面11上的光束L1、L2和L3加以混合,可以讓使用者看到牆面11(例如天花板)呈現柔和均勻的非指向光源,而不會看到多餘的陰影。
The light beam provided by the
在本說明書的一些實施例中,燈具100還可選擇性地(optionally)包括一個第二反射片107,位於殼體101的開口101o外側,且具有一個第對應位於殼體101內部的二反射面107a。在本實施例中,第二反射片107可以是一種金屬板材,可以通過,例如螺栓、螺釘、黏著劑、卡扣或其他合適的固定元件(未繪示),設於固定座102(和
/或透光燈罩103)上,藉以使第二反射面107a面向殼體101的開口101o。
In some embodiments of this specification, the
在本說實施例中,光源105所提供的一部分光束L4,經由第一反射面104a至少一次(例如二次)反射後,形成反射光到達第二反射片107,再經由第二反射面107a的反射返回殼體101的空腔101s之中,再進一步與其他光束進行混光,更有助產生均勻柔和的非指向性光源。
In this embodiment, a part of the light beam L4 provided by the

請參照第6圖,第6圖係根據本說明書的又再一實施例所繪示的燈具600的局部剖面結構放大圖。在本實施例中,燈具600的結構實質上與第3圖所繪示的燈具300類似,差別在於,燈具600的第一反射片包括一個波浪狀結構。在本實施例中,燈具600的第一反射片604的第一反射面604a包含一個第一部分604a1和一個第二部分604a2。第一部分604a1由殼體101的底部101a延伸至殼體101的開口101o,且包括複數個彼此串聯的弧型反射區域R61-R63,形成一個階梯狀結構。第一反射面604a的第二部分604a2與第一部分604a1相連,且延伸並覆蓋於殼體101的底部101a上。

本說明書是提供一種設置於牆面的燈具,其包括一個開口面對牆面的殼體、至少一個位於殼體中的光源以及至少一個位於殼體內壁上的反射片,用以將光源所提供的光束經由反射片進行至少一次反射之後,再由開口向牆面射出,藉以增加光束在殼體內部進行混光的機率,提高出射光的均勻度。 This specification provides a lamp installed on the wall, which includes a housing with an opening facing the wall, at least one light source located in the housing, and at least one reflective sheet located on the inner wall of the housing to provide the light source with After the light beam is reflected at least once by the reflective sheet, it is then emitted from the opening to the wall, thereby increasing the probability of the light beam being mixed inside the housing and improving the uniformity of the emitted light.
雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明,任何該技術領域中具有通常知識者,在不脫離本發明 之精神和範圍內,當可作些許之更動與潤飾,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone with ordinary knowledge in the technical field may not deviate from the present invention. Some modifications and embellishments may be made within the spirit and scope of the invention. Therefore, the protection scope of the present invention shall be determined by the appended patent application scope.
