Description

A kind of TOP LED device

Technical field

The utility model relates to LED encapsulation technology field, relates in particular to a kind of TOP LED device.

Background technology

In the lighting source of new development, light-emitting diode (Light emitting diode, be called for short LED) is owing to have the advantage of low energy consumption, high brightness, becomes the new lamp source of tool potentiality already.In the development of LED, good directionality, brightness is high, and the TOP LED that barrier propterty is good (top light extracting LED) device is a main direction of studying always.Mostly the TOPLED support is that the thermosetting of copper material injection-moulded plastic forms, simple in structure, flexible design, and it is good to go out to fill performance; However, also have certain degree of difficulty in small size TOP LED design, need to consider the thickness and the interior cup required size of copper material, cup both positive and negative polarity spacing was bigger in thick copper material can cause, and a utmost point gold thread bonding is difficulty; Thin copper material can cause both positive and negative polarity bottom spacing less, might cause short circuit during welding.Gap between the both positive and negative polarity of rack upper surface of the prior art is consistent with the gap between the lower surface both positive and negative polarity; This makes when the heat sink support of design demand; Its spacing can only be more than or equal to support copper thickness (0.15mm～0.3mm); At design reduced size product, maybe need use than just being difficult to design in the mug during product of space.

The utility model content

In view of this, the purpose of the utility model is, a kind of TOP LED device is provided, and strengthens the scope of application with simple structure.

For solving the problems of the technologies described above, the technical scheme of the utility model is:

A kind of TOP LED device; Comprise substrate and be arranged on the said substrate and coat the reflective coating of said substrate; The upper surface and the lower surface of said substrate are equipped with positive and negative electrode, and the gap between the upper surface positive and negative electrode is different with the gap between the lower surface positive and negative electrode.

Preferably, the gap between the upper surface positive and negative electrode is less than the gap between the lower surface positive and negative electrode.

Preferably, also be provided with the filling member that runs through the support upper and lower surfaces, the positive and negative electrode on the upper and lower surfaces is separated.

Preferably, said substrate is provided with a groove, and said filling member is filled in the said groove.

Preferably, said filling member and reflective coating are structure as a whole.

Preferably, said groove comprises epimere groove and hypomere groove from top to bottom, and the bore of said epimere groove is less than the bore of hypomere groove, and the shape of said filling member, size and said groove are suitable.

Preferably, said reflective coating covers the edge of the upper surface of said substrate, and covers then face of support relative two at least.

Preferably, said reflective coating covers the edge of the upper surface of said substrate, and two sides that covered substrate is relative at least and extend to the bottom surface, covers the part of bottom surface except that electrode.

Preferably, the length of said TOPLED device is identical with width.

Compared with prior art, the TOP LED device of the utility model is because the gap between the upper surface of base plate both positive and negative polarity is different with the gap between the lower surface both positive and negative polarity; Simple in structure, use widely, be fit to similar special-shaped product structural design; Be particularly useful for undersized TOP led support, wherein, the gap between the upper surface of base plate both positive and negative polarity is narrower; Be no more than 0.15mm, this utilizes product indoor design and explained hereafter; Gap broad between the base lower surface both positive and negative polarity is not less than 0.25mm, and this makes product in use be difficult for causing the solder shorts phenomenon.

Embodiment

In order to make those skilled in the art understand the technical scheme of the utility model better, through concrete embodiment the utility model is done further to specify below.

Referring to Fig. 1～Fig. 4, the TOPLED device in the present embodiment comprises substrate 1 and the reflective coating 2 on the substrate 1 is set, and reflective coating surrounds a reflection cavity 11 with the edges cover of the upper surface of substrate 1, and the longitudinal cross-section of reflection cavity 11 is up big and down small trapezoidal; Reflective coating has also covered two relative sidewalls of substrate, and extends to base lower surface; The positive and negative electrode 12 of upper surface of base plate, the gap L between 13 1 are less than the positive and negative electrode 14 of base lower surface, gap L 2 between 15; Form a groove on the substrate, be filled with a filling member 21 in this groove, this filling member 21 is structure as a whole with reflective coating.The structure of four sides of reflective coating covered substrate in other embodiment, also can be arranged in reflective coating two sides of covered substrate only in the present embodiment; Reflective coating also extends to the lower surface of substrate in the present embodiment, and in other embodiments, reflective coating can only cover the side; And do not extend to the lower surface of substrate; In fact, in order to make the better of reflective coating and substrate bonded, the substrate regions that reflective coating covers should be many as far as possible.

TOP LED device in the present embodiment is because the gap between the rack upper surface both positive and negative polarity is different, simple in structure with the gap between the lower surface both positive and negative polarity; Use widely, be fit to similar special-shaped product structural design, be particularly useful for undersized TOPLED support; As to make length be that 2.1mm, width are the product of 2.1mm, and wherein, the gap between the rack upper surface both positive and negative polarity is narrower; Be no more than 0.15mm, this utilizes product indoor design and explained hereafter; Gap broad between the support lower surface both positive and negative polarity is not less than 0.25mm, and this makes product in use be difficult for causing the solder shorts phenomenon.

More than the utility model has been carried out detailed introduction, use concrete example in the literary composition principle and the execution mode of the utility model set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
