Abstract
The invention provides a high-power light emitting diode (LED) lamp bank without an aluminum base board, which comprises a lamp housing, the LED lamp bank in the lamp housing, and a lamp board mounted on the inner wall of the lamp housing, wherein the LED lamp bank is welded on the lamp board; radiating fins are arranged on the side of the lamp housing, which is opposite to the LED lamp bank; the LED lamp bank consists of a plurality of LED lamp beads; a plurality of evenly-distributed circular holes of which the diameters are larger than the outer diameters of the LED lamp beads are arranged in the lamp board; the LED lamp beads are positioned inside the circular holes; and the bottoms of the LED lamp beads are directly contacted with the inner wall of the lamp housing. The invention additionally provides a preparation process of the high-power LED lamp bank without the aluminum base board. The high-power LED lamp bank without the aluminum base board, which is provided by the invention, has the advantages that a fiberboard which is lower in price is adopted to replace the aluminum base board, so the production cost is greatly lowered and the consumption of aluminum material is reduced; the evenly-distributed circular holes of which the diameters are larger than the outer diameters of the LED lamp beads are arranged in the fiberboard and the LED lamp beads are positioned inside the circular holes, so the LED lamp beads are enabled to be directly and closely contacted with the lamp housing, heat of the LED lamp beads can be directly transferred to the radiating fins of the lamp housing, the radiating effect is improved and the service lives of the LED lamp beads are prolonged.
Description
Technical field
The present invention relates to a kind of LED lamp group, particularly a kind of LED lamp group of not having aluminium base, good heat dissipation effect also relates to its preparation technology.
Background technology
In recent years, plurality of advantages such as long service life, energy consumption are low because the LED light fixture has, rich color have replaced conventional lamp such as tengsten lamp gradually.
Because single LED lamp heating is concentrated relatively, the heat of generation is bigger.And adopt of the lamp plate of high-powered LED lamp group is fixed on the aluminium base on the lamp housing more at present, and the lamp bead weld is connected on the aluminium base.Because at a distance from the layer of aluminum substrate, thereby increased the thermal resistance between them between lamp pearl and the lamp housing, LED lamp place, long-time luminous back heat is higher, thereby causes shorten greatly the service life of LED lamp pearl.Simultaneously, the price comparison of aluminium base is expensive, has increased the manufacturing cost of LED lamp group.
Summary of the invention
The present invention is directed to the problems referred to above of existing high-powered LED lamp group, the no aluminium base high-powered LED lamp group and the preparation technology thereof of a kind of good heat dissipation effect, long service life is provided.
Technical scheme of the present invention: a kind of no aluminium base high-powered LED lamp group; Comprise the LED lamp group in lamp housing, the lamp housing and be installed in the lamp plate on the envelope inner wall; Said LED lamp bond pads is on lamp plate; Said lamp housing is provided with fin back to a side of LED lamp group, and LED lamp group is made up of several LED lamp pearls; Said lamp plate is provided with a plurality of diameters greater than LED lamp pearl external diameter, equally distributed circular hole, and said LED lamp pearl is positioned at circular hole inside, and its bottom directly contacts with envelope inner wall.
Preferably, said lamp plate is a fiberboard, is close on the envelope inner wall.
Preferably, the pin of said LED lamp pearl is the shape that both sides upwarp, and the height between pin and the lamp pearl bottom is greater than the thickness of lamp plate.
Preferably, the circular hole both sides of said lamp plate and the corresponding position of pin are provided with pad, and the pin of LED lamp pearl and the copper conductor that covers of lamp plate are connected as one through pad.
Preferably, the said LED lamp pearl LED lamp pearl that is 1-3W.
The present invention also provides a kind of preparation technology who does not have aluminium base high-powered LED lamp group, carries out according to following steps:
(1) pin with LED lamp pearl is pressed into the shape that both sides upwarp, and make the bottom of LED lamp pearl and the pin that upwarps between height greater than the thickness of lamp plate;
(2) design and manufacturing PCB, the position that the lamp pearl of LED is installed at PCB is provided with the circular hole of diameter greater than LED lamp pearl external diameter, and in circular hole both sides and pin correspondence position pad is set;
(3) PCB is close on the envelope inner wall fixing, two pins of LED lamp pearl are welded on the pad of circular hole both sides, LED lamp pearl bottom is closely contacted with envelope inner wall.
The invention has the beneficial effects as follows: no aluminium base high-powered LED lamp group of the present invention, adopt the lower fiberboard of price to replace aluminium base, greatly reduce production cost, reduced the consumption of aluminium; Fiberboard is provided with even distribution, the diameter circular hole greater than LED lamp pearl external diameter; LED lamp pearl is positioned at circular hole inside, connects with lamp plate at the pad place through the pin that upwarps, and has guaranteed that LED lamp pearl directly closely contacts with lamp housing; The heat of lamp pearl can directly pass on the fin of lamp housing; Thereby reduced thermal resistance, improved radiating effect, prolonged the service life of LED lamp pearl.
