Abstract
The utility model discloses an LED multi-chip power cup energy-saving light which is provided with an LED multi-chip power cup (A), wherein the cup A is composed of a cup body (1) and a cup foot (2), the inner surface of the bottom (1b) of the cup body (1) is a plane, a circuit board is printed on the plane or tightly contacting with an aluminium substrate, LED chips (D) are preset on the printed circuit board, or the LED chips (D) are directly preset on the plane. An electronic component (4) is fixed by welding in space which is formed between the bottom (1b) and the cup foot (2), the electronic component is electrically connected with a lamp cap, and the cup foot (2) is tightly fastened with the lamp cap. The smoothness of the inner surface of the cup body (1) is high, a surface treatment for enhancing the light reflection property is carried out and the front surface of the aluminium substrate printed circuit board is provided with a layer of circuit board reflecting film. Because the LED chips are directly contacted with a radiator, the heat radiation property of the utility model is good and the utility model is suitable for manufacturing LED lighting lamps with large power.
Description
The utility model relates to a kind of illuminating lamp, a kind of specifically LED multicore sheet power cup electricity-saving lamp.
Light emitting diode is long with its power consumptive province, life-span, safety and environmental protection and be subjected to consumer's favor.In the making of LED lamp, for the very little LED lamp of power, the space that it is shared and the heat dissipation problem of lamp are unimportant, thereby can consider.But along with LED lamp power constantly increases, it is of crucial importance and outstanding that these problems just seem.For making than high-power LED lamp, if adopt single light emitting diode only to assemble, then certainly will take very big space, and solder joint is numerous, make troubles to producing, using, and influence attractive in appearance; If with led chip (as aluminium base) assembling on substrate, chip can be arranged very compact, thereby has saved the space significantly.But, the increasing of number of chips along with the increase of led chip density, the heating problem of led chip will be more and more outstanding.
The purpose of this utility model be to provide a kind of take up room less, overcome the led chip heat dissipation problem than the high-power LED power modulation, i.e. LED multicore sheet power cup electricity-saving lamp.
For this reason, the technical solution that the utility model proposes is: a kind of LED multicore sheet power cup electricity-saving lamp, a bowl-shape Lamp cup is arranged, the bottom of Lamp cup is the plane, this plane is in order to the carrying led chip, because chip area is very little, thus can be intensive prefabricatedly put some led chips at the bottom of cup, and Lamp cup is as the radiator of led chip.This programme is suitable for making than high-power LED lamp owing to preferably resolve the heat dissipation problem of LED multicore sheet, thus this Lamp cup we be called LED multicore sheet power cup.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is the utility model structural representation, also is an embodiment of the present utility model.In accompanying drawing 1, bowl-shape Lamp cup A is made of cup 1 and cup pin 2, wherein cup 1 is made of body of wall 1a and cup end 1b, and the upper surface of cup end 1b is the plane, and this plane is in order to the carrying led chip, for example on aluminium base 3, preset a large amount of led chip D, chips welding is intact, qualified after testing after, with transparent resin adhesive with chip and welding lead encapsulation thereof, again aluminium base 3 is sticked together closely with cup end 1b, so that conduct heat; With lead the exit of led chip on the aluminium base is passed 1b in the cavity of cup pin 2; 4 of the control circuits of control led chip operate as normal are put in glass pin 2 and the formed cavity of cup end 1b, and an end of control circuit 4 links to each other with the led chip exit, and the other end is that power supply links to each other with lamp holder.The effect of Lamp cup mainly contains three: one, carrying led chip; Its two, as the radiator of a large amount of led chips, for this reason, Lamp cup is to be made by heat dispersion good metal material; Its three, play good reflective, optically focused effect, for this reason, fineness required very high when the inner surface of the cup 1 of Lamp cup was made, and electrodepositable reflector layer or do the surface treatment that other is intended to strengthen reflecting effect, simultaneously, the front of aluminium base 3 can be coated with a book layer circuit board reflectance coating.
For led chip positive and negative electrode exit chip on same all, the aluminium base of narrating previously 3 in order to preset led chip also can.This is another embodiment of the present utility model.Its scheme be exactly led chip directly is preset at glass at the bottom of the inner surface of 1b, chip chamber directly welds.Welding finishes and after the assay was approved led chip and chips welding lead-in wire is encapsulated with transparent resin adhesive.
Need to prove the said Lamp cup of the utility model, but also can make respectively at textural its cup 1 and cup pin 2 integral manufacturings; But the body of wall 1a of same cup 1 and cup end 1b integral manufacturing also can be made respectively.The geometry of cup can be varied, and for example its cross section can be circle, regular polygon etc.
The utility model is because the heat dissipation problem of a large amount of chips is solved preferably, and therefore, the LED lamp that is suitable for making bigger power is alleged LED multicore sheet power cup electricity-saving lamp.
