The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Below in conjunction with specific embodiment, realization of the present utility model is described in detail.

embodiment mono-

As shown in Figure 1, 2, conductive spacer 4 and securing member 5 that the LED lighting device that the utility model embodiment provides comprises base plate 1, a plurality of LED module 2 and a plurality of LED modules 2 sequentially is fixed in to described base plate 1 and their are electrically connected to, described LED module 2 is fixedly arranged on substrate 7 by one or plurality of LEDs 6 and forms.Substrate described in the utility model 7 can be single-sided aluminum-base plate, single face copper base, single face glass-fiber-plate or single face cardboard, can also be the electronic line plates such as double-face aluminium substrate, double-side copper substrate or two-sided glass-fiber-plate, or even multiaspect aluminium base.Substrate described in the present embodiment 7 is preferably single-sided aluminum-base plate (only the positive aluminium base of establishing circuit), and plurality of LEDs 6 is distributed in the front of establishing substrate 7, so that the illumination of this LED lighting device is even.Described securing member 5 successively screws in described base plate 1 through conductive spacer 4 and substrate 7, and described conductive spacer 4 is electrically connected to adjacent LED module 2.Can when a plurality of LED modules 2 are fixed in to described base plate 1, make like this their be electrically connected to, kill two birds with one stone, easy and simple to handle, again because of described securing member 5 and conductive spacer 4 structures extremely simple, easily obtain, greatly reduced the cost of this LED lighting device.

Base plate described in the utility model embodiment 1 is electric conductor, described securing member 5 is metal screw or metal buckle, described metal screw or metal buckle are arranged with the insulation sleeve 8 that itself and conductive spacer 4 and LED module 2 electricity are isolated outward, described insulation sleeve 8 one ends have the dead ring 9 of screw terminal 50 or metal buckle and conductive spacer 4 electricity isolation, and described conductive spacer 4 has the through hole passed for the metal screw.Electric current in 2 transmission of described LED module can not conduct to base plate 1 like this, safety, reliable.Wherein, described conductive spacer 4 can be annular sheet metal.Described metal screw, annular sheet metal and insulation sleeve 9 all can be designed to standard component, so that cost further reduces.

Usually, described substrate 7 roughly is " ∠ " shape, establishes the first breach 71 and the second breach 72 in its straight flange end and hypotenuse middle part, as shown in Figure 3.The first breach 71 of adjacent LED module forms with time together with the second breach 72 abuts against the installing hole passed for described securing member 5, and described the first breach 71 and the second breach 72 are preferably semicircle breach, and the installing hole formed by its spelling is circular.After adjacent LED module 2 is installed on described base plate 1, described conductive spacer 4 is squeezed in adjacent substrate 7 and makes it to be electrically connected to.Bulk substrate as raw material can be cut into to polylith " ∠ " shape substrate 7 like this, stock utilization is high, as shown in Figure 4.

As shown in Figure 5,6, also can establish circular mounting hole 73 in straight flange end, hypotenuse middle part or the bending part of " ∠ " shape substrate 7.Adjacent LED module 2 is installed on base plate 1 near rear by described securing member 5 and conductive spacer 4 like this, and described conductive spacer 4 is squeezed in adjacent substrate 7 and makes it to be electrically connected to.Now, preferably select the conductive spacer that external diameter is larger, so that at 2 conductive electric currents of adjacent LED module.
