Description

A kind of high efficiency array-type LED encapsulating structure
Technical field
The utility model relates to a kind of high efficiency array-type LED encapsulating structure, belongs to LED lighting technology category.
Background technology
As shown in Figure 1, the led array encapsulating structure that generally uses is to form circuit on a metal circuit board 1 on the market, and this circuit is built-in with led chip 2, and connects a lead 3 to bonding wire point from chip 2, covers chip through a glue 4; This kind led array encapsulating structure chip is more concentrated, therefore heating also can be more concentrated, directly have influence on radiating effect,, cause luminous efficiency low because of the radiating effect difference so plant the led array encapsulating structure because the good and bad degree of radiating effect is directly proportional with luminous efficiency; In addition, because the chip array area is bigger, when directly putting glue, packing colloid is difficult to form higher projection, because total reflection effect in the optics, the part rayed that chip sends is when the interface of colloid and air, can be because incident angle can't penetrate greater than Brewster's angle, if adopt the method for molding or use the anti-packing colloid that hangs down and flow, though can form certain projection, the consumption of packing colloid can increase on the one hand, on the other hand, light is the propagation distance lengthening in colloid, and packing colloid has a negative impact to luminous efficiency to the absorption meeting of light.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of high efficiency array-type LED encapsulating structure, and it is rational in infrastructure, perfect heat-dissipating, and the light extraction efficiency height, and luminosity is strong.
For achieving the above object, the utility model adopts following technical scheme:
A kind of high efficiency array-type LED encapsulating structure; form by a metal circuit board, plurality of LEDs chip, lead and packing colloid; it is characterized in that: the connected mode design according to led chip on the metal circuit board has certain configuration; led chip is positioned on the solid brilliant position of metal circuit board; and be connected in the position of bonding wire of metal circuit board with respective wire; the led chip array is kept off cushion rubber and is divided into plural zone; packing colloid is in the retaining cushion rubber; and protruding certain altitude, led chip and lead are protected.
The another technical problem that the utility model solves is: the connected mode design according to led chip on the metal circuit board has certain configuration, the circuit connecting mode of led chip can be series, parallel, string and series-parallel connection, also can array way connect, led chip quantity can be adjusted according to demand.
The another technical problem that the utility model solves is: the led chip array is kept off cushion rubber and is divided into plural zone, the retaining cushion rubber can be the certain thickness printing ink circle of printing on the plate of direct-on-line road that has, also can make, fit together with metal circuit board then by other materials such as metal, potteries.
The another technical problem that the utility model solves is: packing colloid is in the retaining cushion rubber, and protruding certain altitude, and led chip and lead are protected.Used packing colloid can be a silica gel, also can be other encapsulating materials commonly used such as silicones, epoxy resin.
The another technical problem that the utility model solves is: metal circuit board is provided with the both positive and negative polarity pad or passes the PIN pin of metal circuit board, is used for forming connection with external power source.
The another technical problem that the utility model solves is: metal circuit board can be made into square, circular, rhombus according to concrete operating position, perhaps other arbitrary shapes, and can cooperate the assembling needs thereon, design various location, mounting structure.
Another technical problem to be solved in the utility model provides a kind of LED encapsulating structure, and a pad or PIN pin are respectively established in the metal circuit board both sides, can be directly on pad or PIN pin bonding wire be connected with outside line;
Because the led chip array is divided into zone more than two, the method of employing point glue just can form the projection of certain altitude, and reducing owing to area, required packing colloid consumption reduces significantly, the light that chip sends also reduces greatly in the absorption loss of packing colloid, by above technical measures, when reducing cost, improved the light extraction efficiency of array light source.
Compared with prior art, the beneficial effects of the utility model are:
1, member is simple, and is reasonable in design, and volume is little, the power height;
2, heat dispersion is good, and luminescent lifetime is long, can continue for a long time to light, and durable in use, luminosity is strong;
3, light extraction efficiency height reaches identical illuminating effect, and required led chip quantity is few, and production cost is low, energy savings during use.
