Embodiment
In order to solve the not good defect of existing waterproof effect in prior art, innovative point of the present invention is: the outsourcing portion 112 that is provided for coated pedestal pad 2 connecting portions 22 on pedestal 1, due to by outsourcing portion 112 is set, pedestal 1 and the length of pedestal pad 2 in conjunction with gap are increased, so solved of the prior art to the not good defect of pedestal pad 2 waterproof effects.Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 2, the utility model provides a kind of Full-color SMC, comprise pedestal 1 and be no less than the pedestal pad 2 of, pedestal 1 comprise a portion 12 and in be formed with reflector 111 bowl body 11, pedestal pad 2 is placed in a portion 12, and pedestal pad 2 is folded between bowl body 11 and seat portion 12.Each pedestal pad 2 comprises welding disk 21, pin 23 and for connecting the connecting portion 22 of welding disk 21 and pin 23; Welding disk 21 extend into reflector 111 inside at least partly, and pin 23 extends to pedestal 1 outside.Bowl body 11 also comprise 1 be coated on connecting portion 22 outsides, for lengthening pedestal 1 and the outsourcing portion 112 of pedestal pad 2 in conjunction with gap length.
Concrete, on welding disk 21, being welded with LED wafer, this LED wafer is exposed to reflector 111 inside jointly with at least part of welding disk 21.Connecting portion 22 is folded between bowl body 11 and seat portion 12.As preferred embodiment, the wall of a portion 12 and bowl body 11 is close to respectively in the both sides of connecting portion 22.
Bowl body 11 can be formed in one and also can be and removably connect with seat portion 12.The utility model adopts bowl body 11 and the 12 split settings of seat portion, is the mode removably connecting and connects, and is convenient to the installation of pedestal pad 2.For pedestal pad 2 is better fixed, on welding disk 21, offer at least one hole, pedestal 1 is provided with the projection suitable with hole, and being embedded in above-mentioned hole of projection interference fit, to position and to fix pedestal pad 2.
The number of pedestal pad 2 is no less than one.Preferably, the number of pedestal pad 2 is four, and between each pedestal pad 2, being 90 ° of angles and insulation, to be arranged at ringwise equably a portion 12 circumferential.
By the connecting portion of pedestal pad 2 22 is coated on to pedestal 1 inside by outsourcing portion 1121, can lengthen pedestal 1 and pedestal pad 2 in conjunction with gap length, therefore can improve the water resistance of element.The path (S1 shown in figure and S2) that concrete steam as shown in Figure 1 and Figure 3 contacts with pedestal pad 2 through coating Waterproof glue line, known in the Full-color SMC of the present utility model shown in Fig. 3, steam must be walked around outsourcing portion 112 and could contact with pedestal pad 2, the length of S2 is obviously greater than the length of S1, effectively increase the length of anti-water route, improved the water resistance of element.
In order to reach waterproof effect, the height of Waterproof glue line 3 must be exposed to higher than pedestal pad 2 height of pedestal 1 Outboard Sections simultaneously.The height of the Waterproof glue line 3 ' of the full-color mount components in Fig. 1 must be higher than the height of connecting portion 22 ', and the height of Waterproof glue line 3 only need to be higher than the height of pin 23 in Fig. 3, Full-color SMC of the present utility model can reduce encapsulating height to a great extent, making full-color mount components be mounted on matrix 4(is for example pcb board) upper convenient, with low cost.
The shape of connecting portion 22 has no particular limits, and can be " | " type structure, and " \ " property structure, "/" structure or " Z " shape structure, as long as being coated on outsourcing portion 112 inner sides, pedestal 1 is inner.Preferably, in the utility model, welding disk 21 is " one " character form structure, and connecting portion 22 is that connecting portion 22 forms " L " shape tabs jointly with welding disk 21 along " | " shape structure of extending away from reflector 111 directions.
Meanwhile, pin 23 is arranged at the bottom of pedestal 1.In the time there is coating Waterproof glue line 3 in outside, can increase the distance of steam from coating Waterproof glue line 3 to pin 23 in greatest limit ground, can further improve element water resistance.
Pin 23 is "-" shape structure and jointly forms " Z " font tabs with welding disk 21 and connecting portion 22.But shape structure that pin 23 is also not limited to above-mentioned " " can be the structure of other shapes such as " " or "/".Concrete, pin 23 is to be bent to form dorsad from one end away from welding disk 21 of connecting portion 22 and welding disk 21.Welding disk 21, pin 23 and connecting portion 22 bending angle are between any two 70 °～120 °, preferred, and in the utility model, selecting the bending angle between pin 23 and connecting portion 22 is 90 °, have saved use convenient manufacture of material.
Moreover the wall away from welding disk 21 of multiple pins 23 is placed on same plane, facilitate paster, and paster is smooth.
In addition, outsourcing portion 112 free ends circumferentially extend out formation step, and step 113 is covered on pin 23 tops.Be step 113 by outsourcing portion 112 free ends along being bent to form in the same way with pin 23, and these step 113 shapes and pin 23 shapes suitable.Because pin 23 and step 113 fit, in the time that being carried out to paster, can improve full-color subsides element pasted on surface the evenness of paster; For example, and step 113 can be opposite to the protection that the pin 23 of step 113 belows carries out physically, is prevent distortion, bending or fracture, so that pin 23 is more smooth, makes element Horizontal consistency in the time mounting better; Meanwhile, the existence of step 113 has increased the distance to pin 23 by Waterproof glue line 3 surfaces in the horizontal, has increased anti-water route.
In order to make waterproof effect better, step 113 ends flush in or exceed pin 23 ends.
To sum up, Full-color SMC of the present utility model, by making connecting portion 22 be coated in pedestal 1 by outsourcing portion 112 and pin 23 is arranged to the bottom of pedestal 1, can improve element water resistance; Can make pin 23 more smooth by paste step 113 protection above pin 23, make element Horizontal consistency in the time mounting better and can further improve water resistance.
Although the present invention describes by specific embodiment, it will be appreciated by those skilled in the art that, without departing from the present invention, can also carry out various conversion and be equal to alternative the present invention.In addition, for particular condition or material, can make various amendments to the present invention, and not depart from the scope of the present invention.Therefore, the present invention is not limited to disclosed specific embodiment, and should comprise the whole execution modes that fall within the scope of the claims in the present invention.
