Abstract
The utility model relates to an LED and discloses a light concentration type SMD LED. The SMD LED comprises a bowl-shaped SMD support. An LED chip is fixed on the bowl-shaped SMD support bottom The upper surface of the LED chip is coated with a phosphor powder layer. An elliptical lens is arranged on the phosphor powder layer in a dispensing curing way. The bottom diameter of the elliptical lens is smaller than the height of the elliptical lens. The light concentration type SMD LED has the advantage of direct light concentration.
Description
Technical field
The utility model relates to LED, especially relates to a kind of light-focusing type SMD LED.
Background technology
The primary stage of producing at electronic circuit board, via hole assembles fully by manually completing.After first batch of automatic machinery is released, they can place some simple pin elements, but complicated element still needs manual placement can carry out wave-soldering.Element pasted on surface was released before about 20 years, and had started a new era at this point.From the passive component to the active element and integrated circuit, finally all become surface mount device (SMD) and can have been assembled by picking up the equipment of putting.Within a very long time, people think that all pin elements finally all can adopt the SMD encapsulation.
SMD LED is exactly the meaning of surface labeling LED, and the SMD paster contributes to production efficiency to improve, and the application of different facility.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on a support, and an end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Traditional SMD LED structure be as shown in Figure 1 in the bowl cup of SMD support fixed wafer, connect bonding wire, then at SMD support bowl cup mid point, apply glue the glue of fluorescent material (or be mixed with) to slightly lower than edge, the formation concave shape.This series products lighting angle is 110 degree normally.And the SMD LED that obtains less lighting angle just need to increase a secondary lens in following process, the increase of secondary lens can affect the luminous stability of LED, can cause simultaneously and produce shortcoming complicated, that product cost raises.
Summary of the invention
Need to increase the shortcoming of secondary lens for overcoming traditional SMD LED optically focused, the utility model provides the SMD LED of the direct optically focused of a kind of energy.
The purpose of this utility model is achieved through the following technical measures, a kind of light-focusing type SMD LED, comprise bowl-type SMD support, the bowl bottom of described SMD support is fixed with the LED wafer, described LED upper wafer surface is coated with a phosphor powder layer, on described phosphor powder layer, the some adhesive curing is provided with ellipse shape lens, and the bottom surface diameter of described ellipse shape lens is less than the height of ellipse shape lens.
Concrete, described LED wafer is starched the bowl bottom that cements in described SMD support by silver, and toasts 120 minutes under 175 degree conditions, so that the silver slurry fully solidifies.
As a kind of optimal way, the bottom surface diameter of described ellipse shape lens lighting angle 80 degree is 103: 140 with high ratio.
As a kind of optimal way, described LED chip passes through gold thread, silver-colored line, copper cash, aluminum steel or alloy wire and the binding of SMD support.
The utility model, by one-time formed mode, forms suitable lens at the SMD rack surface, forms light-focusing type SMD LED, makes its rising angle reach the 60-90 degree.This one-time formed collector lens, have higher stability; Can save secondary lens in application, avoid the restriction of secondary lens light transmittance, reduce the cost of light fixture simultaneously.
The accompanying drawing explanation
The cross-sectional view that Fig. 1 is traditional SMD LED;
The cross-sectional view that Fig. 2 is the utility model embodiment.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
As Fig. 2, a kind of SMD LED of optically focused 80 degree, comprise a bowl-type SMD support 4, LED chip 2 use silver slurries are fixed in SMD support 4, and toast 120 minutes under 175 degree conditions, so that the silver slurry fully solidifies, then adopt gold thread (or silver-colored line, alloy wire) by LED chip 2 and support 4 bindings, coat fluorescent material 3 silica gel of fluorescent material (or be mixed with) at LED chip 2 surface points again, and through the baking of 1 hour of 150 degree, thereafter, utilize and once put the molding mode of adhesive curing, form ellipse shape lens 1 on SMD support 4 surfaces, the type SMD LED that forms optically focused 80 degree of take is example, the product sectional structure chart as shown in Figure 2, the bottom surface diameter of these ellipse shape lens 1 is 2.8MM, high 2.06MM (can make its rising angle reach the 60-90 degree when adjusting the bottom surface diameter with high ratio.)
More than that the utility model light-focusing type SMD LED is set forth; for helping to understand the utility model; but execution mode of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be equivalent substitute mode, within being included in protection range of the present utility model.
