By using the structure, the light emitting diode realizes light emission on both sides, thereby effectively increasing the light emitting angle and having simple structure and strong practicability; the light emitting angle can be 360 degrees at most; and the light emitting diode is applied to batch production.
Description
Technical field
The utility model relates to a kind of semiconductor device, relates in particular to a kind of light-emitting diode (LightEmitting Diode is called for short LED).
Background technology
LED is a kind of solid-state semiconductor device, and it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply.Semiconductor wafer is made up of three parts, and a part is a P type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N type semiconductor, mainly is electronics here, the middle normally quantum well in 1 to 5 cycle.When electric current acted on this wafer by lead, electronics and hole will be pushed to quantum well, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in quantum well.And the light wavelength color of light just is by the material decision that forms the P-N knot.
There is the layer of transparent cover conventional LED outside, has filled transparent resin between LED luminescence chip and translucent cover.The lighting angle of this LED depends on the mechanical form of translucent cover and the optical index of transparent resin, and its luminous angle is relatively poor, is generally 12 °-15 °, can only observe luminosity from the front.As shown in Figure 1, Chinese invention patent specification CN1417869A (open day is on May 14th, 2003) discloses a kind of middle hollow LED light-emitting diode, utilizes reflected refraction to increase lighting angle in the principle of externally dispersing, thereby reaches 80 °-90 °.
Above-mentioned is direct insertion LED device, and the adopting surface mounted LED device is arranged in addition, but all adopts unidirectional bright dipping form.Generally use up lens at the outgoing window and handle, so its maximum shooting angle has certain directive property smaller or equal to 180 °, great majority are applied to indication and demonstration field.Along with the raising of LED performance and the expansion of application, the LED lamp of this unidirectional bright dipping, aspect night scene light fixture (as: lamp string), compare with conventional bulb, the unidirectional directive property that it is intrinsic, cause visual angle less, influence attractive in appearance, also make simultaneously the LED device energy-conservation, the life-span long and photochromic good advantage is subjected to very big folding and supports.
The utility model content
Technical problem to be solved in the utility model provides a kind of bilateral bright dipping, and the big light-emitting diode of lighting angle.
For solving the problems of the technologies described above, the utility model provides a kind of light-emitting diode, comprise: support, transparent enclosure resin, gold thread, led chip, fluorescent material and crystal-bonding adhesive, the center of described support is hollow-core construction or transparent configuration, described led chip two ends are fixed on the center of described support by described crystal-bonding adhesive, the both sides bright dipping of described led chip, described transparent enclosure resin-encapsulated is in the both sides up and down of described support.
The utility model is realized the bilateral bright dipping by said structure, has effectively increased lighting angle (lighting angle maximum can to 360 °), and simple in structure, and exploitativeness is strong, is fit to produce in batches.

Embodiment
As shown in Figures 2 and 3, light-emitting diode of the present utility model, comprise: support 1, transparent enclosure resin 2, gold thread 3 (being wire), led chip 4, fluorescent material and crystal-bonding adhesive (figure does not show), the center of support 1 is a hollow-core construction (or transparent configuration, figure does not show), led chip 4 two ends are fixed on the center of support 1 by crystal-bonding adhesive.Preferably, support 1 is surface mount (SurfaceMount Technology is called for short a SMT) support, and crystal-bonding adhesive is elargol or insulating cement.Led chip 4 both sides bright dippings, transparent enclosure resin 2 is encapsulated in the both sides up and down of SMT support 1, and preferably, the transparent enclosure resin is an epoxy resin.
Further, SMT support 1 of the present utility model can be selected two kinds of transparent material and nontransparent materials, and when SMT support 1 was transparent material, the lighting angle of light-emitting diode of the present utility model can reach 360 °; When SMT support 1 was nontransparent material, the lighting angle scope of light-emitting diode of the present utility model was 240 °-360 °.
The utility model can 360 ° of bright dippings, and non-directive has every advantage of spot light; For the light fixture of the two-way bright dipping of needs, the general easier formation of LED can reduce LED quantity, reduces cost, and improves reliability.
