Description
Technical field
The present invention relates to the LED fluorescent tube that a kind of LED makes illuminator.
Background technology
Existing LED fluorescent tube, adopt LED to make illuminator to be stained with heat-conducting glue and to be attached on the heat radiation heat transfer aluminium section bar more, aluminium section bar and PC cover seamless fastening to be made, though the aluminium section bar temperature only was about 55 ℃ when LED made the bright lamp of the fluorescent-lamp tube of illuminator, but because that the thermal insulation of PC cover and lower printing opacity shape make that LED makes the hood-shaped enclosure space temperature that becomes of illuminator and PC is higher, and the propagation loss of light is bigger, with normally used T8 pipe 20W is example, cavity temperature can reach 75 ℃ when 25 ℃ of environment temperatures, this makes the node temperature of led chip reach 100 ℃, and higher temperature can have a strong impact on the service life of LED fluorescent tube.And the propagation loss of light reaches 15%.Relatively poor by blue coloured light and the complementary white light colour rendering that forms of yellow fluorescent powder, if adopt yellow red mixed light powder then light decay is big especially, when the LED fluorescent tube applies to general lighting, its colour rendering can't reach instructions for use, generally only can reach the Ra value now only is about 50, and the Ra value must reach more than 70 when applying to general lighting.Existing LED fluorescent tube adopts the pcb board printed circuit as light source board, the LED that emits white light is realized that by printed circuit on the pcb board series connection back forms low-voltage module and links with the constant-current supply controller, the output of constant-current source is consistent with the voltage that low-voltage module is set low-voltage end, input consistent with the voltage of external voltage (generally adopting 220V and 110V).Make the fluorescent tube of illuminator with regard to existing LED, no matter its illuminator is to adopt the direct plug type light pearl of rectangular electrode to make illuminator, still adopt on the aluminium base of pcb board formula directly nation to decide led chip and make illuminator, perhaps adopt SMD lamp pearl to be bonded on the pcb board, because the architectural characteristic of pcb board is limited than the selection of big and radiating treatment mode as the integrated power of light source especially lighting source, the utilization of LED illuminator is restricted, when technical measures that this restriction takes increase difficulty of processing cost is significantly risen for overcoming.The LED that uses makes the fluorescent-lamp tube of illuminator at present, raising along with chip lumen per watt number, current density constantly increases, heat dissipation problem has become the LED illuminator as in the integrated utilization of lighting source, especially in the next very distinct issues of the airtight service condition of fluorescent-lamp tube, for the junction temperature of chip that makes LED is controlled at below 60 ℃, according to a large amount of evidences, the heat that the selection of LED fluorescent tube case material must make the LED illuminator send does not have under the situation of temperature field sudden change should make the temperature on surface should be controlled at (environment temperature is 25 ℃) below 50 ℃, generally speaking adopt following three kinds of modes to realize the rapid unofficial biography of junction temperature usually, make the thermal equilibrium temperature of fluorescent lamp surface of shell reach requirement: one, the surface area that adds the metal fin at the large chip binding face back side, two, at seal head end pressure ventilating fan, three are set, between illuminator and lamp casing, fill cooling fluid.First kind of mode is limited to the improvement of heat radiation, the second way has increased the power consumption and the manufacturing cost height of fluorescent tube, failure likelihood in using in addition increases, though the third mode has solved heat dissipation problem preferably, the propagation quality of the integrated light of LED illuminator is not done effectively to improve.Because the opposing surface of bright dipping end that the architectural characteristic of existing pcb board makes LED make illuminator can't be processed into the surface of high reflective characteristic, so light extraction efficiency has descended 10% to 20%.Common LED fluorescent-lamp tube is owing to adopt the constant pressure and flow mode as power supply, except that the cost that significantly increases the LED fluorescent-lamp tube, because rolling up of electronic device significantly reduces its reliability, a large amount of facts have proved as long as the electric current by LED is effectively limited, and it is to guarantee the effective of LED fluorescent-lamp tube and long-life work fully that current-limiting circuit promptly is set.Therefore all there is defective in above-mentioned fluorescent-lamp tube with the pcb board printed circuit, need improve.
