Abstract

The utility model relates to a light-emitting diode with an improved structure, which comprises a base, a light reflecting cup, a plurality of chips, an adhesive layer and a glass lens, wherein, power connecting pins are arranged on the base. The light reflecting cup is correspondingly arranged in the base, and the light reflecting cup and the base yoke with one another. A concave section is formed in the light reflecting cup. All the chips are arranged in the concave section of the light reflecting cup, and are respectively and cooperatively connected with each power connecting pin. The adhesive layer coats and binds the light reflecting cup in the base, each corresponding electrical connection chip, leads and the power connecting pins. The bottom surface of the light reflecting cup is exposed out of the adhesive layer, and each extensive power connecting pin on both sides of the base is also extended and exposed out of the adhesive layer. The glass lens is arranged on the position corresponding to the chips, and is filled with necessary fluorescence powder. Thereby, the high melting point characteristic of glass is favorably used to provide supreme heat resistance effect and to enhance the entire reliability.

Description

Structure improved light-emitting diode

Technical field

The utility model relates to a kind of structure improved light-emitting diode, especially finger is a kind of can add glass lens by the corresponding position in chip, and the design of interpolation phosphor powder in the glass lens, make the utility model be different from general traditional approach (as: epoxy resin or the optical mirror slip made from PC, PMMA, PEI, PC/PMMA and COC), and has excellent heat-resisting effect, and promote whole reliability, and be applicable to large-scale display board, sales field, display lighting, various advertisement plate and lighting tool ... wait or the structure of similar articles.

Background technology

General existing light-emitting diode (as shown in Figure 1), it is made of two 71,72 on supports that are packaged in the light-permeable colloid 7, and in this wherein an end of a support 71 be provided with a recessed groove 711, this recessed groove 711 is provided with a chip 73, this chip 73 is connected with another support 72 with a gold thread 74, and this recessed groove 711 is packaged with a fluorescent layer 8, constitutes a light-emitting diode in this way, and makes light-emitting diode send colored light sources by fluorescent layer 7; Though, above-mentioned light-emitting diode can reach the effect of sending colored light sources, but the light-permeable colloid 7 of the packaged usefulness of this light-emitting diode and both thermal endurances of fluorescent layer 8 of being located on the recessed groove 711 of support 71 are low, so still do not meet the required of user on reality is used.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of structure improved light-emitting diode is provided, add glass lens by corresponding position in chip, and the design of interpolation phosphor powder in the glass lens, make and the utlity model has excellent heat-resisting effect, and promote whole reliability, increase its practicality.

For reaching above-mentioned purpose, the utility model provides a kind of structure improved light-emitting diode, includes a pedestal, a reflector, several chips, a glue-line and a glass lens.This pedestal is provided with power pin; This reflector correspondence is located in the pedestal, mutually combines and form, and forms a depressed part in this reflector; Each chip is arranged in the depressed part of this reflector, and is coupled to each power pin with lead respectively; This glue-line envelope is established in conjunction with the reflector in this pedestal, each corresponding chip, lead and power pin that electrically connects, and this reflector bottom surface exposes to outside this glue-line, and each power pin that extends of these pedestal both sides also extends and exposes to outside this glue-line; This glass lens is located at the corresponding position of chip, and adds phosphor powder in the glass lens; Thus, so that excellent heat-resisting effect to be provided, and promote whole reliability.

Above-mentioned and other purpose and advantage of the present utility model are not difficult to obtain to understand in depth from the detailed description and accompanying drawing of following selected embodiment.

Certainly, the utility model is at some in addition on part, or allows in the arrangement of part differently in addition, but selected embodiment then in this specification, described in detail, and shows its structure in accompanying drawing.

Embodiment

Now with a preferred embodiment and conjunction with figs. describe in detail the utility model in after.

See also Fig. 2, the utility model is a kind of structure improved light-emitting diode, and this structure improved light-emitting diode comprises:

One pedestal 1, the both sides on this pedestal 1 are provided with power pin 11.

One reflector 2, these reflector 2 correspondences are located in the pedestal 1, mutually combine and form, and form a depressed part 21 in this reflector 2, and this reflector 2 can be pottery, plastics or the metal material person of making.

Several chips 3, each chip 3 is arranged in the depressed part 21 of this reflector 2, and is coupled to each power pin 11 with lead 4 respectively.

One glue-line 5, these glue-line 5 envelopes are established in conjunction with the reflector 2 in this pedestal 1, each corresponding chip 3, lead 4 and power pin 11 that electrically connects, and these reflector 2 bottom surfaces expose to outside this glue-line 5, and each power pin 11 that extends of these pedestal 1 both sides also extends and exposes to outside this glue-line 5.

One glass lens 6, this glass lens 6 is located at the corresponding position of chip 3, and these glass lens 6 peripheries are located on the pedestal 1, and add necessary phosphor powder 61 in the glass lens 6.

Constitute a kind of structure improved light-emitting diode by above-mentioned structure, see also Fig. 2, characteristics of the present utility model are to add glass lens 6 by the corresponding position in chip 3, and interpolation phosphor powder 61 in the glass lens 6, be beneficial to the high-melting-point characteristic of utilization glass,, make to the utlity model has excellent heat-resisting effect so that excellent heat-resisting effect to be provided, and promote whole reliability, increase its practicality.
