The heat dissipation performance of the LED lamp is promoted, the whole bulb emits light, and the cost is reduced; the weight is lightened, condensed water is prevented from being produced on the inner wall of the lamp, and glare is prevented; and the LED lamp has longer service life with lower cost and is more attractive and practical, so the LED lamp has the condition in the field of indoor illumination.
Description
Technical field
The present invention relates to lighting device, especially relate to a kind of LED lamp of energy heat radiation performance.
Background technology
The LED lamp is compared common scalding lamp, fluorescent lamp, electricity-saving lamp and is had obvious superiority.Energy-efficient, than the energy-conservation 60%-80% of traditional energy-saving lighting lamp; Environmental protection, without infrared ray, radiationless without stroboscopic without ultraviolet ray, can frequently open the harmful elements such as not mercurous and xenon.Belong to real environmental protection lighting source; Extra long life can reach 30,000 to 50,000 hours service life, is 30 times of common bulb; Safe and reliable, earthquake-proof function is strong, and the required voltage electric current is little, and caloric value is few, does not produce potential safety hazard; Applied range can be used for general lighting, solar lighting, and also available decorative lighting also can be used for city lighting cosmetic treatment etc.Along with becoming better and approaching perfection day by day of LED emitting integral technology, the LED illumination will obtain to use more widely.
But under present technical merit, also have many factors restricting the paces of LED illumination development.Dispelled the heat into a bottleneck in the LED illumination application.LED is when work, and PN junction can generate heat, if the thermal conductance that produces can not be gone out, makes junction temperature maintain reasonable level, and the light decay of LED will be very serious.Therefore, reasonably Design of Luminaires is satisfying outside other index of light fixture, and a key request is that heat dispersion will be got well, ball bulb especially, and paster is just had higher requirement to heat radiation by the sealing of ball bubble.For this reason, designers use different Heat Conduction Materials and have designed various radiator structures, make great efforts to reduce junction temperature, but present heat dissipation technology are ripe not enough, causes the light decay of LED bulb lamp also not come up to the expectation.The LED bulb lamp obtains must seek more efficiently radiating mode before the widespread adoption.In addition, the radiator structure that generally adopts at present is exterior radiator, but this mode not only affects the outward appearance of LED lamp, and has increased weight and the manufacturing cost of lamp.
Summary of the invention
The objective of the invention is objective requirement for the LED lamp under the above-mentioned technical background provides a kind of heat radiation, reduces manufacturing cost, weight reduction and improves the long-life LED lamp of outward appearance.
Technical solution of the present invention is that the LED lamp comprises support, constant-current driving power supply, lucite shell with light diffusing, aluminum-based circuit board, the LED paster, the surface that it is characterized in that the aluminium substrate of aluminum-based circuit board is provided with the heat-radiation coating bed of material, is provided with the gas inserts of high thermal conductivity coefficient in the bulb.
Above-described aluminum-based circuit board is one or more, linearly shape or U-shaped, perhaps spirality.
Aluminum-based circuit board of the present utility model is one or more, and its tail end is curved.
The heat-radiation coating bed of material of the present invention can be ZS-411 radiation cooling dope layer.
The thickness of above-described ZS-411 radiation cooling dope layer can be 0.2-0.3mm.
The gas inserts of the high thermal conductivity coefficient in the bulb of the present invention can be the gaseous mixture inserts of helium inserts or hydrogen inserts or hydrogen and helium.
Operation principle of the present invention is that the aluminium substrate gas interior with being sealed in bulb fully contacts, after the heat that the LED post-chip produces exports on the aluminium substrate, a part exhales with ultrared form, another part then imports rapidly gas in the bulb, import to shell by gas in the bulb again, be dispersed into outside the lamp at last.The thermal conductivity factor of air is 0.0233W/ (m ﹒ ℃) in the time of 0 ℃, and helium is 0.144 W/ (m ﹒ ℃), and hydrogen is 0.163 W/ (m ﹒ ℃), and leading coefficient during the rising temperature also will increase.This shows that when replacing air to be filled in the bulb lamp with helium or hydrogen, heat-transfer rate has increased by 6 to 7 times, by means of the gas of heat radiation coating and high thermal conductivity coefficient, the integral heat sink performance of this structure lamp has obtained obvious lifting.The aluminium substrate length and the radian that are welded with the low-power LED paster can be made adjustment with the shape of bulb outer wall, are evenly distributed thereby make apart from luminous point on the sphere at the equidistant place of ball bubble inwall, have guaranteed that the LED lamp can obtain the aesthetic of whole body uniform illuminating.In addition, behind filling helium or the hydrogen, lower when the gas humidity ratio fills air in the lamp, heat conduction is rapider in addition in the lamp, and gas temperature is more even in the lamp, and the temperature of lamp housing is just more even, thereby has eliminated the common condensed water of present LED bulb inner wall.This design take aluminium substrate, helium or the hydrogen, heat radiation coating and the organic material shell that disperse as radiator structure has replaced the simple alloy material radiator heat-dissipation design generally adopted at present, junction temperature has been dropped to lower temperature not using in the heat radiator dedicated situation; The use of special lamp housing material has also obtained desirable energy-conservation and anti-dazzle effect, thereby has reduced again manufacturing cost when having improved the outward appearance of LED lamp.
Advantage of the present invention is the heat dispersion that has promoted the LED lamp, makes the bulb entirely lighting, has alleviated weight, has reduced cost; Avoided the lamp inwall can produce condensed water, prevented the generation of dazzle, thereby made the LED lamp obtain the longer life-span and more attractive in appearance and practical with lower cost, and then made it possess the condition that enters the room lighting field.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is three-dimensional exploded view of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, the present invention mainly comprises lamp holder 1, support 2, constant-current driving power supply 3, lucite shell 4, aluminum-based circuit board 5, LED paster 6.Described aluminum-based circuit board 5 is 8, and the tail end of aluminum-based circuit board 5 is with lucite shell 4 crooked curved being arranged in the ball bulb.Aluminum-based circuit board 5 also can be linear, U-shaped or spirality.Power be 0.1 watt LED paster 6 to be welded on width be that 0.56cm thickness is on the aluminum-based circuit board 5 of 1mm, the power of LED paster 6 also can be selected in 0.06-1 watt scope.Be coated with one deck heat-radiation coating bed of material 7 on the surface of aluminum-based circuit board 5.The heat-radiation coating bed of material 7 is ZS-411 radiation cooling dope layers, and the thickness of ZS-411 radiation cooling dope layer is 0.25 mm, and its thickness also can be selected in the scope of 0.2-0.3mm.The lucite shell 4 of bulb is to add the light inlet dispersant in the transparent organic materials such as PMMA or PC, aid in again optical design, make this lucite shell 4 have unusual high light transmission and good light diffusing, thereby obtained desirable energy-conservation and anti-dazzle effect.Fill the gas filler 8 of full high thermal conductivity coefficient in the bulb under normal pressure, described gas inserts 8 is helium inserts, or the hydrogen inserts, also can be the gaseous mixture inserts of hydrogen and helium.The aperture of the central authorities of lamp holder 1 is used for bleeding and inflating simultaneously, after other part assemblings of LED lamp are finished, vacuumizes from aperture, then sucks helium or hydrogen, at last with the aperture of fluid sealant with conduction nut water tight lamp holder 1.
