Description

燈夾及其應用之燈具 Lamp clip and its application lamps

本揭露書是有關於一種燈夾及其應用，特別是一種具有可動夾持件的燈夾及其應用。 This disclosure relates to a lamp clip and its application, in particular to a lamp clip with a movable clamping piece and its application.

傳統照明裝置，例如吊燈、嵌燈、檯燈等，多半為固定式且體積較大。當使用者僅需局部照明或是局部加強照明時，例如僅需對顯示器的螢幕(例如桌機的螢幕、筆記型電腦的螢幕等)進行局部照明時，一般使用可固定於螢幕上使用的燈具，使燈源鄰接顯示器的螢幕。 Traditional lighting devices, such as chandeliers, recessed lamps, table lamps, etc., are mostly fixed and large in size. When the user only needs local lighting or local enhanced lighting, such as only local lighting on the monitor screen (such as desktop screens, laptop screens, etc.), generally use lamps that can be fixed on the screen. , Make the light source adjacent to the monitor screen.

目前市面上已有可固定於螢幕上使用的燈具。例如使用夾具夾持固定的燈具，其整個結構重量係由夾具支撐，夾具的一端夾設於螢幕設置的(上)邊緣，另一端固持燈具。由於夾具是以相對兩個面夾持在顯示器的螢幕邊框和螢幕背板之間，隨著螢幕邊框逐漸變窄的設計趨勢，夾具的夾持面積遭到壓縮，使得傳統的夾具可能無提供足夠的夾持力來穩固地固定燈具。再加上曲面螢幕和超薄螢幕的出現，如何因應不同型態螢幕的邊框設計提供燈具穩固的夾持功能，同時兼顧夾具整體的美觀與完整性，已成為該技術領域的重要課題。 At present, there are lamps that can be fixed on the screen and used on the market. For example, for a lamp that is clamped and fixed by a clamp, the weight of the entire structure is supported by the clamp. One end of the clamp is clamped on the (upper) edge of the screen, and the other end holds the lamp. Since the clamp is clamped between the screen frame and the screen backplane of the monitor on two opposite sides, with the design trend of the screen frame becoming narrower, the clamping area of the clamp is compressed, so that the traditional clamp may not provide enough The clamping force to firmly fix the lamp. Coupled with the emergence of curved screens and ultra-thin screens, how to provide a stable clamping function for lamps according to the frame design of different types of screens, while taking into account the overall beauty and integrity of the fixture, has become an important issue in this technical field.

因此，有需要提供一種先進的燈夾及其應用，來解決現有技術所面臨的問題。 Therefore, there is a need to provide an advanced lamp clip and its application to solve the problems faced by the prior art.

本說明書的一實施例揭露一種燈夾，用以將燈源固定於物件上，此燈夾包括：第一夾持件以及第二夾持件。第一夾持件，包括：燈源固定部、連接部和止擋部。燈源固定部用以固定燈源。連接部與燈源固定部連接。止擋部可動地與連接部連接，且具有一個止擋表面，可選擇地固定於連接部上複數個位置之一者上。第二夾持件與連接部連接，用以將物件夾制於止擋表面和第二夾持件之間。 An embodiment of this specification discloses a light clip for fixing a light source on an object.

The second clamping member is connected with the connecting part and used for clamping the object between the stop surface and the second clamping member.

本說明書的另一實施例揭露一種燈具，用以選擇性的夾持於顯示器的上緣，此顯示器具有顯示面與背面，此燈具包括：燈源、第一夾持件以及第二夾持件。第一夾持件，包括：連接部和止擋部。連接部與燈源連接。止擋部可動地與連接部連接，且具有一個止擋表面，可選擇地位於連接部上的第一位置與第二位置。第二夾持件與連接部連接，當燈具夾持於顯示器的上緣時，止擋表面碰觸顯示面的第三位置，第二夾持件碰觸背面，其中當止擋表面於第一位置時，燈源與第三位置顯示面具有第一距離，當止擋表面於第二位置時，燈源與第三位置顯示面具有第二距離，第二距離大於第一距離。 Another embodiment of this specification discloses a lamp for being selectively clamped on the upper edge of the display. The display has a display surface and a back surface. The lamp includes: a light source, a first clamping member, and a second clamping member . The first clamping member includes: a connecting part and a stop part. The connecting part is connected with the light source. The stopping part is movably connected with the connecting part and has a stopping surface, which can be selectively located at a first position and a second position on the connecting part. The second clamping member is connected with the connecting part. When the lamp is clamped on the upper edge of the display, the stop surface touches the third position of the display surface, and the second clamping member touches the back surface. In the position, the light source has a first distance from the third position display surface. When the stop surface is at the second position, the light source has a second distance from the third position display surface, and the second distance is greater than the first distance.

根據上述實施例，本說明書的實施例是在提供一種燈夾及其應用，其包括二個夾持件，用來將燈源固定於物件上。此二個夾持件中至少有一個具有一個可動的止擋部，以非彈性的往復方式，可動地連接於對應的夾持件上，用以提供穩固的夾持力，進而將燈源固定於此物件上。 According to the above-mentioned embodiment, the embodiment of this specification is to provide a lamp clip and its application, which includes two clamping members for fixing the lamp source to the object. At least one of the two clamping members has a movable stopper, which is movably connected to the corresponding clamping member in a non-elastic reciprocating manner to provide a stable clamping force and thereby fix the lamp source On this object.

另外，藉由調整止擋部的位置，可以彈性地調整二夾持件之間的夾持距離，以適用於不同形式或不同厚度尺寸的物件；或是在不變更被夾持物件形式和厚度尺寸的前提下，藉由調整止擋部的位置，來調整被夾持物件與燈源之間的距離。因此，可以在不影響燈夾原本結構的完整性與美外的前提下，依照使用者的操作需求，改變夾持距離或燈源與物件之間的距離，提高使用的方便性與可靠度。 In addition, by adjusting the position of the stopper, the clamping distance between the two clamping members can be adjusted elastically to be suitable for objects of different forms or different thickness sizes; or without changing the form and thickness of the clamped object Under the premise of size, the distance between the clamped object and the light source can be adjusted by adjusting the position of the stopper. Therefore, the clamping distance or the distance between the light source and the object can be changed according to the user's operation requirements without affecting the original structural integrity and beauty of the light clip, thereby improving the convenience and reliability of use.
