Description
Technical field
Electronics member device field is the utility model is related to, is related specifically to a kind of metab.
Background technology
The center of the metab used in the packaged type of light emitting diode is mostly burnishing surface structure at present
Or having the small recess structure of chip placement, the product that such design encapsulates metal pipe cap points to angle and determined by top lens
It is fixed, therefore cause sensing angle larger relatively low with photoluminescence intensity, it is narrow to be only applicable to application, the applications such as Close approach switch
The shortcomings that.
Utility model content
The utility model provides a kind of metab, for solving to point to angle in the packaged type of light emitting diode at present
It is larger relatively low with photoluminescence intensity, the narrow technical problem of application.
In order to solve the above-mentioned technical problem, the utility model provides a kind of metab, including：Base 1, the first pin
2 and second pin 3, the center at the top of base 1 is provided with bowl-type recess 4；The top of base 1 is surrounded by least one
Individual through hole；The second pin 3 at least one, the second pin 3 pass through the chip electricity on the through hole, with the base 1
Connection；First pin 2 is connected with the base 1.
Further, the base 1 is hollow structure, the hollow space implantation glass glue of the base 1.
Further, for the material of base 1 using iron-nickel alloy and gold-plated, thickness of coating is 2 μm.
Further, the recess of the bowl-type recess 4 and bottom surface are tangent.
Further, the side wall of the bowl-type recess 4 uses mirror surface treatment.
Further, the top of base 1 is surrounded by a through hole, the second pin 3 totally one.
Further, completely cut off between the second pin 3 and the base 1 with glass cement.
A kind of metab provided by the utility model, it is recessed by setting up bowl-type on the center at the top of metab
The light modulation structure of mouth, have and collect rising angle, enhancing part goes out the effect of luminous intensity, so as to expand answering for light emitting diode
Use scope.
Brief description of the drawings
Fig. 1 is a kind of metab structural representation provided by the utility model.
Embodiment
Referring to Fig. 1, the utility model provides a kind of metab, including：Base 1, the first pin 2 and second pin 3.
The material of base 1 is 2 μm using iron-nickel alloy and gold-plated, thickness of coating in the present embodiment, can so make its electrical characteristics excellent
Good and good appearance；And in order to mitigate product weight, product after balance group is vertical, base 1 is designed to hollow structure, and base
1 hollow space implantation glass glue, the wall thickness of base 1 are designed as 0.2mm, and the metab so designed can use the side of punching press
Formula is made.The center at the top of base 1 is provided with bowl-type recess 4, in the present embodiment in order to realize the top center of base 1
The design of position bowl-type recess 4, the height of base 1 are designed as 2mm, and the design of bowl-type recess 4 of the base 1 of metal is specially：Bottom surface
It is 6mm circle for diameter, depth 0.6mm, slightly larger than chip height, the above is a diameter of 1.4mm circle, and recess is designed as half
Footpath is 0.7mm circular arc, and tangent with bottom surface, and so design collects aggregation with being relatively beneficial to chip top surface and lateral emitting, together
When bowl-type recess 4 side wall use mirror surface treatment, the light extraction of side can so projected after reflection by front, Jin Erda
To the purpose for reducing light extraction sensing angle.The top of base 1 is surrounded by least one through hole, and the first pin 2 is connected with base 1,
The first pin 2 is welded with base 1 in the present embodiment；Second pin 3 to one or more, second pin pass through on base 1
Through hole be directly higher by plane on base 1, be higher by height in the present embodiment and be designed as 0.35mm, and second pin 3 and base 1
Between completely cut off with glass cement, be allowed to insulate between base 1.3rd pin simultaneously can be recessed by gold thread and the top bowl-type of base 1
Other electrodes of 4 chips of mouth carry out bond adhesion, to realize the electrical connection of chip and external structure.Bottom in the present embodiment
The top of seat 1 is surrounded by a through hole, and second pin 3 totally one, second pin 3 passes through the chip on through hole, with base 1 to be electrically connected
Connect.
A kind of metab provided by the utility model, it is recessed by setting up bowl-type on the center at the top of metab
The light modulation structure of mouth, have and collect rising angle, enhancing part goes out the effect of luminous intensity, so as to expand answering for light emitting diode
Use scope.
It should be noted last that above embodiment is only illustrating the technical solution of the utility model rather than limit
System, although the utility model is described in detail with reference to example, it will be understood by those within the art that, can be right
The technical solution of the utility model is modified or equivalent substitution, without departing from the spirit and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
