About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to graphic a plurality of embodiment, can clearly present.The direction term of mentioning in following examples, such as " on ", D score, 'fornt', 'back', " left side ", " right side " etc., only be the direction with reference to annexed drawings.Therefore, the direction term of use is explanation, but not is used for limiting the present invention.
Fig. 1 is the top view of the slim light fixture of one embodiment of the invention.Fig. 2 is the partial top view of backboard and the light source of Fig. 1.Please refer to Fig. 1 and Fig. 2, the slim light fixture 100 of present embodiment comprises a main body 110 and a light source 120.Light source 120 for example is light emitting diode (Light-Emitting Diode, LED) light source and is disposed in the main body 110 that main body 110 has a backboard 112 and a framework 114, and framework 114 is disposed on the backboard 112 and covers light source 120.Backboard 112 has at least one fluting 112a (illustrating as a plurality of), and the end of fluting 112a extends to an edge 112b of backboard 112 and is opened on edge 112b.When the heat that produces when light source 120 was passed to backboard 112, backboard 112 can temperature distortions and change the width W 1 of fluting 112a.
Under this configuration mode, the fluting 112a that is opened on the edge 112b of backboard 112 provides the space of backboard 112 in the distortion of edge 112b place.When backboard 112 received from light source 120 hot, the width W 1 of fluting 112a can change because of backboard 112 temperature distortions, uses to absorb backboard 112 because of the deflection that temperature rises and produces, avoids backboard 112 to produce the phenomenon of twisting.
The optical sheets such as configurable LGP, reflector plate and diffusion sheet on the backboard 112 of present embodiment are so that light source 120 can see through these optical sheets and uniform illuminating ray is provided.
The material of the backboard 112 of present embodiment for example is metal, so that overall structure has better intensity.In general, the degree of metal material temperature distortion is comparatively remarkable, as above is set forth in backboard 112 and forms fluting 112a, can effectively absorb the deflection of the backboard 112 of metal material, avoids backboard 112 because of the torsional deformation that is heated.In addition, the part of backboard 112 more contiguous light sources 120, it is more remarkable to receive the degree that heats up from the heat of light source 120.Therefore, in the present embodiment, fluting 112a is arranged at the position of contiguous light source 120, with the deflection of effective absorption backboard 112.
These flutings 112a of present embodiment for example is the edge 112b that is distributed in backboard 112.Right the present invention is as limit, in other embodiments, and the Temperature Distribution after these flutings 112a can be heated according to backboard 112 or the demand in other design and other suitable distribution mode is arranged.
Fig. 3 is the schematic diagram that the slim light fixture of Fig. 1 is hung on ceiling.Please refer to Fig. 3, the slim light fixture 100 of present embodiment can comprise at least one messenger wire 130 (Fig. 3 is plotted as many), and main body 110 is hung on by messenger wire 130 and for example is a stiff end 50 of ceiling.Be in the situation of Suspensory lamp shown in Figure 3 at slim light fixture 100, backboard 112 temperature distortions of Fig. 1 and Fig. 2 and cause integrally-built distortion meeting more obvious, as above be set forth in backboard 112 and form fluting 112a, can effectively absorb the deflection of the backboard 112 of Suspensory lamp, avoid backboard 112 because of the torsional deformation that is heated.
In the present embodiment, backboard 112 has at least one circular hole 112c (Fig. 1 illustrates as a plurality of), each circular hole 112c connects corresponding fluting 112a away from the end of edge 112b, and the degree of concentrating to reduce the terminal stress of fluting 112a avoids backboard 112 to produce slight crack at fluting 112a place.The present invention not length of cross-notching 112a and the size of circular hole 112c is limited, and below by graphic this is illustrated.
Fig. 4 is the partial top view of backboard and the light source of another embodiment of the present invention.Please refer to Fig. 4, in the present embodiment, when the heat that produces when light source 220 was passed to backboard 212, the P1 of first of backboard 212 had the first temperature, and the second portion P2 of backboard 212 has the second temperature, and described the first temperature is higher than described the second temperature.One of them of those flutings 212a is positioned at the P1 of first and has the first length L 1, and wherein another of these flutings 212a is positioned at second portion P2 and has the second length L 2, the first length L 1 greater than the second length L 2.In other words, the fluting 212a that the present embodiment part setting that temperature is higher after backboard 210 is heated is long is with the deflection of effective absorption backboard 212.In other embodiments, the demand in the Temperature Distribution after each 212a that slots can be heated according to backboard 212 or other design and be designed to other suitable length, the present invention is not limited this.
Fig. 5 is the partial top view of the backboard of another embodiment of the present invention.Please refer to Fig. 5, similar in appearance to the backboard 112 of Fig. 2, the backboard 312 of present embodiment is provided with fluting 312a at its edge 312b, and is provided with circular hole 312c at fluting 312a end, the degree of concentrating to reduce the terminal stress of fluting 312a avoids backboard 312 to produce slight crack at fluting 312a place.The backboard 312 of present embodiment and the backboard 112 of Fig. 2 different are in, the aperture D1 of the circular hole 112c of Fig. 2 greater than the width W 1 of fluting 112a, and the aperture D2 of the circular hole 312c of present embodiment equal the to slot width W 2 of 312a.In other embodiments, circular hole 312c can have other suitable aperture, and the fluting 312a can have other proper width, the present invention is not limited this.
In sum, have at least following one of them advantage in the above embodiment of the present invention, slotted openings makes backboard have the space of distortion in its edge in the edge of backboard.When backboard received from light source hot, the width of fluting can change because of the backboard temperature distortion, used to absorb that backboard Yin Wendu rises and the deflection that produces avoids backboard to produce the phenomenon of distortion.
The above, it only is preferred embodiment of the present invention, when the scope that can not limit with this invention process, the simple equivalence of namely generally being done according to claims of the present invention and invention description content changes and modifies, and all still belongs in the scope that patent of the present invention contains.In addition, arbitrary embodiment of the present invention or claims must not reached whole purposes or advantage or the characteristics that the present invention discloses.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the present invention.In addition, the terms such as " first " mentioned in this specification or claims, " second " are only in order to the title of naming element (element) or distinguish different embodiment or scope, and are not the quantitative upper limit of limiting element or lower limit.
