Description
Technical field:
the present invention relates to a kind of LED bulb lamp and preparation method.
Background technology:
The incandescent lamp power consumption height that
are traditional, the life-span is short, under the overall situation of global resources anxiety, is forbidden producing by national governments gradually.The product that thereupon substitutes is an electronic energy-saving lamp, though electronic energy-saving lamp has improved energy-saving effect, owing to used the heavy metal element of many contaminated environment, runs counter to the main trend of environmental protection.Along with the high speed development of LED technology, the selection of LED illumination becoming gradually novel green illumination.LED is at principle of luminosity, and is energy-conservation, on each aspect of environmental protection, all is far superior to traditional illuminating product.
are because incandescent lamp and electronic energy-saving lamp still occupy very high ratio in people's daily use; In order to cut the waste; LED illumination exploitation must meet present interfaces and people's use habit; People need not changed under the situation of original lamp holder and circuit, just can use the LED illuminating product of a new generation.So, be that the LED bulb lamp of light source just arises at the historic moment with LED.
bulb lamp has adopted the present interfaces mode, i.e. screw socket, socket mode (E27 etc.), and in order to meet people's use habit, its profile has also adopted the profile of imitation incandescent lamp.The LED-based characteristics of luminescence, the structure of LED ball bulb wants complicated with respect to incandescent lamp.Basically be divided into light source, drive circuit and heat abstractor.These parts cooperate jointly could bring up low power consuming, the LED bulb lamp product of long-life, high light efficiency and environmental protection.But present LED bulb lamp quality is very different, still has many problems to need to solve.
when work, have only 30% electric energy to be converted into luminous energy, all the other electric energy of about 70% all are converted into heat energy, therefore need radiator and dispel the heat.LED has serious light decay under the temperature condition with higher, if heat can not effectively distribute, with illuminating effect that influences the LED bulb lamp greatly and service life.And the purpose that the LED bulb lamp produces is to substitute traditional incandescent lamp, and its volume size must be suitable with traditional incandescent lamp, has so limited the heat sink size size of LED bulb lamp greatly, thereby has limited the raising of LED bulb lamp power.
Summary of the invention:
the purpose of this invention is to provide a kind of good radiator structure that has, and water resistance is good, and safety is attractive in appearance, the LED bulb lamp and the preparation method of long service life.
Above-mentioned purpose realizes through following technical scheme:
a kind of LED bulb lamp, its composition comprises: standard lamp head, described standard lamp head connects the power supply shell that has power supply; Described power supply shell connects the lamp housing shell; In the described lamp housing shell lamp housing substrate is housed, described lamp housing substrate connects the LED lamp plate, and described lamp housing shell connects lampshade; Described LED lamp plate connects described power supply, and described LED lamp plate connects described power supply through contact pin.
described LED bulb lamp, described lamp housing shell has cooling fin; Or the lamp housing shell do not have cooling fin and described power supply shell has louvre, and described louvre connects waterproof breathable membrane; Between described lamp housing shell and the described lampshade sealing ring is housed, between described lamp housing shell and the described power supply shell sealing ring is housed.
described LED bulb lamp, described lampshade are that to add light diffusing agent be material to PC; Described lamp housing shell is 6063 aluminium alloys; Described power supply shell is the PBT plastics; Described lamp holder is the lamp holder of standard; Described light source is the LED of every 1W of 120 ° of lighting angles, colour temperature 3000K-5000K.
The preparation method of
a kind of LED bulb lamp is fixed on the LED lamp plate on the lamp housing substrate, and lampshade is through buckle or be adhesively fixed and fix on the lamp housing, and the led light source cover is got up; Lamp housing substrate and lamp housing shell weld together, and the power supply that has the power supply shell is placed on the lamp housing enclosure, and lamp holder is fixed on the plastic casing of power supply.
The preparation method of
described LED bulb lamp, between the heat sink and lamp housing substrate of each the LED lamp on the LED lamp plate, welding with eutectic is the technology of metal welding, and LED and lamp housing are directly welded together; Perforate below each LED lamp on the led circuit plate at the opposite position of corresponding with it lamp housing substrate, is done some convexities, uses the method for eutectic weldering in the space of the two, welds together with the lamp housing substrate LED is heat sink.
Beneficial effect:
The heat of LED bulb lamp of the present invention is produced when luminous by LED, and the heat radiation process is divided into two steps, and the heat of LED is transmitted to the radiator of bulb lamp; Radiator is delivered to heat in the air; Realized better heat radiating effect,
On
LED lamp plate 3. of the present invention, adopt the technology of eutectic weldering between the heat sink and lamp housing substrate of each LED, LED and lamp housing are directly welded together; It is that thermal conductivity factor is high that metal welding, its maximum characteristics are in the eutectic weldering again; On the led circuit plate, the following perforate of each LED is at the opposite position of corresponding with it lamp housing substrate; Make some convexities, use the method for eutectic weldering in the space of the two, weld together with the lamp housing substrate LED is heat sink; Effectively reduced the thickness of eutectic soldering paste like this; Effectively reduced the thermal resistance between the two, improved the heat transference efficiency between the two, the heat that LED is produced effectively is delivered on the lamp housing rapidly.
