Abstract
The utility model discloses a plug-keyboard LED which comprises at least one LED chip, a lens used for encapsulating the LED chip, as well as an anode pin and a cathode pin which are electrically connected with the LED chip. The plug-keyboard LED also comprises a bridge-shaped structure which is arranged in the lens for limiting the relative movement between the anode pin and the cathode pin. By the structure, the bridge-shape structure can keep the distance between the anode pin and the cathode pin from changing, thereby greatly improving the reliability of the LED, and meanwhile further firming the connection between the lens and the anode pin and the cathode pin.
Description
Technical field
The utility model belongs to light emitting diode (LED, Light-emitting Diode) technical field, more particularly, relates to a kind of direct insertion LED.
Background technology
Please refer to Fig. 1, be the structural representation of direct insertion LED in the prior art, it comprises lens 101, anodal pin 102, negative pole pin 103, passes through the led chip 104 that gold thread 105 is electrically connected with anodal pin 102 and negative pole pin 103.Lens 101 are made by epoxy resin usually, but the radiating effect of epoxy resin is poor, thereby the temperature of led chip 104 is raise, and the temperature rise of led chip 104 causes its internal resistance to increase, thereby advance to produce light decay.And silica gel has heat dispersion preferably, the lens that adopt silica gel to replace epoxy resin to make can improve the light decay problem greatly, but because the hardness of silica gel is lower, the distance between anodal pin 102 and the negative pole pin 103 changes because of external force easily, thereby cause gold thread 105 fractures, make the dead lamp of LED.
The utility model content
The technical problem that the utility model embodiment will solve is to provide a kind of direct insertion LED, is intended to solve the problem of the poor reliability that the LED that adopts silica-gel lens in the middle of the prior art exists.
The technical solution of the utility model is: a kind of direct insertion LED is provided, comprise at least one light-emitting diode chip for backlight unit, the encapsulation described light-emitting diode chip for backlight unit lens and anodal pin that is electrically connected with described light-emitting diode chip for backlight unit and negative pole pin, described direct insertion LED also comprise one in described lens in order to limit the bridge-like structure of relative motion between described anodal pin and the negative pole pin.
Compared with prior art, technique scheme is provided with in lens in order to limit the bridge-like structure of relative motion between described anodal pin and the negative pole pin, distance is difficult for changing between anodal pin and the negative pole pin, thereby improved the reliability of LED greatly, simultaneously because the effect of bridge-like structure, being connected between lens and anodal pin and the negative pole pin is also more firm.
Description of drawings
Fig. 1 is the structural representation of direct insertion LED in the prior art;
Fig. 2 is the structural representation of the utility model one preferred embodiment.
The specific embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 2, preferred embodiment for the utility model direct insertion LED, it comprises the lens 201 of light-emitting diode chip for backlight unit 204, encapsulation LED chip 204 and anodal pin 202 and the negative pole pin 203 that is electrically connected with light-emitting diode chip for backlight unit 204 by gold thread 205, be to strengthen the reliability of direct insertion LED, in lens 201 are provided with in order to limit the bridge-like structure 206 of relative motion between anodal pin 202 and the negative pole pin 203.Like this, because the effect of bridge-like structure 206, distance just is difficult for changing between anodal pin 202 and the negative pole pin 203, gold thread 205 also just is difficult for being damaged, thereby improved the reliability of LED greatly, simultaneously because the effect of bridge-like structure 206, being connected between lens 201 and anodal pin 202 and the negative pole pin 203 is also more firm.
Be provided with a cup-shaped depressed part 207 in negative pole pin 203 tops, the quantity of light-emitting diode chip for backlight unit 204 can be for one or more, and it is installed in the depressed part 207 of negative pole pin 203, and the bottom of depressed part 207 is provided with one deck elargol 208.
In the present embodiment, bridge-like structure 206 can be plate-like or strip, and it draws angle 202,203 with positive and negative electrode and links together.In principle, distance changes between anodal pin 202 and the negative pole pin 203 as long as bridge-like structure 206 can limit, and it can also adopt C shape, U-shaped etc., and other are applicable to the shape of use.
In the present embodiment, bridge-like structure 206 is made by epoxy resin, lens 201 are made by silica gel, because the silica-gel lens good heat dissipation, can improve the light decay problem of LED light fixture greatly, the wavelength drift is little when the LED temperature control is good, thereby the control colour temperature, because the quality of epoxy resin is hard than silica gel, and epoxy resin is transparent material, thereby the location that can realize anodal pin 202 and negative pole pin 203 well, and can the illumination effect of light-emitting diode chip for backlight unit 204 not exerted an influence.Certainly, bridge-like structure 206 can also adopt other hard, transparent and material that have a high Tg point (being glass transition temperature, Glass Transition Temperature) to make.
During production, the epoxy resin that constitutes bridge-like structure 206 is in a liquid state and is directed in bridge-like structure 206 moulds, anodal pin 202 and the negative pole pin 203 that to adjust distance then combine with liquid-state epoxy resin, after treating the epoxy resin cooling, bridge-like structure 206 promptly fuses with anodal pin 202 and negative pole pin 203.Then, the silica gel that constitutes lens 201 is in a liquid state and is directed in lens 201 moulds, bridge-like structure and the positive and negative electrode pin components that fuses combined the encapsulation that can realize direct insertion LED with liquid-state silicon gel.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
