The specific embodiment

Hereinafter with reference to relevant drawings, so that preferred embodiment of the present utility model to be described, wherein components identical will be illustrated with identical reference marks.

Please refer to Fig. 2 A and Fig. 2 B, it shows the preferred embodiment of light-emitting device of the present utility model, illuminator 23 is vertically set on one first substrate 21, each first substrate 21 is provided with a plurality of illuminators 23, this first substrate 21 has a plurality of flat tabular protuberances 211, first substrate 21 and the protuberance 211 on it are for be arrangeding in parallel, this protuberance 211 extends outstanding by first substrate 21, oblique cutting is in the 22 corresponding perforates 221 of second substrate, this perforate 221 is also replaceable to be the groove of ccontaining this protuberance 211, first substrate 21 and second substrate 22 are circuit board, has circuit layout on it, fixing with scolding tin 24 welding to each other, and by scolding tin 24 electric connections.In addition, on protuberance 211, has a perforation 2111, it provides scolding tin 24 to be filled in perforation 2111 inside and both sides, to increase the robustness that protuberance 211 combines with perforate 221,2111 inwalls of boring a hole have a tin metal layer, make scolding tin 24 be filled in perforation 2111 inside easily, this perforation 2111 is preferably a circular hole or a long slot bore.In the present embodiment, scolding tin 24 is welded on the below of second substrate 22, and it also can be welded on the top of second substrate 22 according to actual needs.

Above-mentioned illuminator is preferably a tubular, circle shape, rectangle or SMD type light emitting diode, and above-mentioned light-emitting device is preferably a lighting device or a car lamp device.

See also Fig. 3 A and Fig. 3 B, when needs are adjusted illuminator 23 angles, because the protuberance 211 of first substrate 21 is fastened first end 2211 of the perforate 221 of second substrate 22 by the below, and fasten second end 2212 of the perforate 221 of second substrate 22 by the top, therefore, change perforate 221 first ends 2211 of second substrate 22 and the distance between second end 2212, can change the angle that first substrate 21 tilts, because illuminator 23 is vertically set on first substrate 21, so the angle of illuminator 23 also can change along with the angle of first substrate 21.Distance bigger (as the D1 of Fig. 3 A) when first end 2211 and second end 2212, the angle that tilts between first substrate 21 and second substrate 22 also bigger (as Fig. 3 A α 1) then, when the distance littler (as the D2 of Fig. 3 B) of first end 2211 and second end 2212, the angle also little (as Fig. 3 B α 2) that tilts between first substrate 21 and second substrate 22 then.
