Specific embodiment

To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Go out all other embodiments obtained under the premise of creative work, shall fall in the protection scope of this application.

As shown in Figure 3-Figure 5, the light source assembly of the application includes offering illumination window 11,1 and of substrate of welding hole 12 It is arranged on the light source 2 of illumination window 11.Welding hole 12 is equipped with the soldering opening 121 connected with illumination window 11.Light source 2, which is equipped with, to be prolonged The exit 21 of welding hole 12 is extended, light source 2 is fixed on substrate 1 by the way that exit 21 to be welded in welding hole 12 to realize On.

Since soldering opening 121 is connected with illumination window 11, when welding exit 21, welding gun can be from illumination window 11 It tilts through soldering opening 121 and enters in welding hole 12.In this way, such as welding wire 3 can be set in welding hole 12, pass through welding gun Welding wire 3 is melted, so that exit 21 is fixed on welding hole 12.Therefore, set through the above way, can not have to click and enter tin Cream carries out Reflow Soldering again, simplifies flow chart, easy to operate, stable, reliable, works well, climbs electric safety, be easy to fixed light source 2。

To achieve the above object, each component of light source assembly can be set in many ways, below with specific embodiment Exemplified by, the construction of each component is discussed in detail.

Substrate 1 can be PCB (Printed Circuit Board, printed circuit board (PCB)) plate, or other kinds of Substrate 1.The size of substrate 1 can be set according to demand.

Illumination window 11 is the through hole through substrate 1, shape and the form fit of light source 2, can be circle, rectangle etc.. Light source 2 can be mounted in illumination window 11 by the area of illumination window 11 less times greater than the area of light source 2 with facilitating.

Welding hole 12 is also the through hole through substrate 1, and there are many set-up modes of welding hole 12.In one example, weld The periphery that hole 12 is arranged on illumination window 11 is connect, the periphery of welding hole 12 towards substrate 1 protrudes from illumination window 11.Welding hole 12 The position connected with illumination window 11 be arranged to soldering opening 121.The side wall opposite with soldering opening 121 of welding hole 12 is configured to Welding surface 122, the periphery of welding surface 122 towards substrate 1 protrude from illumination window 11.So set, it can need on substrate 1 The position of welding additionally sets the welding hole 12 of protrusion, reduces the area of illumination window 11.

Copper facing is carried out on substrate 1 on the welding surface of welding hole 12, the side copper facing positioned at 1 side of substrate is formed, passes through side Copper facing turns on 1 internal wiring of substrate and light source 2, and is welded welding wire on substrate 1 by side copper facing.Side copper facing can be direct Plating is on substrate 1, identical with usually in 1 front of substrate or the copper-plated generation type in the back side.

When needing to weld exit 21 on substrate 1, welding wire 3 is placed in exit 21, welding gun is from illumination window 11 tilt through soldering opening 121, carry out side soldering, welding wire 3 is melted and is fixed on welding surface 122.Exit 21 exists at this time Welding hole 12 is fixed under the action of welding wire 3.

After being welded, welding wire 3 is entirely located in welding hole 12, that is to say, that one end of the separate exit 21 of welding wire 3 is not Protrude from welding hole 12.In this way, can not have to design welding surface 122 on substrate 1 keeps away position, space is saved.

The size of welding hole 12 can specifically be set according to demand.Two welding holes 12 can be set on substrate 1, two Welding hole 12 is located at the opposite end of illumination window 11 respectively, so as on the basis of 2 fixation of light source, reduces welding hole 12 number simplifies structure, facilitates processing, installation.

In the setting example of another welding hole 12, illumination window 11 is in addition to for setting light source 2, also as welding hole 12, the welding surface 122 of the partial sidewall of illumination window 11 as welding hole 12.By taking illumination window 11 is circle as an example, illumination window The shape that mouth 11 and welding hole 12 are formed is regular circular.At this point, the area of illumination window 11 can be more than the face of light source 2 Product reserves the welding space of welding gun.

Light source 2 can be COB light source 2, or LED (light emitting diode) lamp bead, wherein COB (Chip On Board) light source 2 is that the specular removal that LED chip is placed directly against on the mirror metal substrate 1 of high reflecting rate is integrated 2 skill of area source Art.

The illuminator of the application can be shot-light, downlight, Grille lamp etc..The illuminator includes above-mentioned light source group Part.In the illuminator, since soldering opening 121 is connected with illumination window 11, when welding exit 21, welding gun can be from photograph Window 11 is penetrated to tilt through soldering opening 121 and enter in welding hole 12.In this way, such as welding wire 3 can be set in welding hole 12, Welding wire 3 is melted by welding gun, so that exit 21 is fixed on welding hole 12.Therefore, set through the above way, it can not Reflow Soldering is carried out again with tin cream is clicked and entered, and simplifies flow chart.

The foregoing is merely embodiments herein, are not limited to the application.For those skilled in the art For, the application can have various modifications and variations.All any modifications made within spirit herein and principle are equal Replace, improve etc., it should be included within the scope of claims hereof.
