The specific embodiment
Principle of the present utility model is: LED driving power and LED pipe directly are welded in the ceramic lamp base bottom, heat directly in time distributes by ceramic lamp base and metal spiral shell, greatly reduce the thermal resistance of intermediate heat transfer, the heat that LED and power supply are sent can directly spread out of heat by ceramic lamp base, so that the LED bulb lamp not only cost is lower, light decay is less, and use saferly, be conducive to applying of LED lamp.
The below describes the utility model with reference to the accompanying drawings in detail, and it is more obvious that the purpose of this utility model and effect will become.
Such as Fig. 1 and shown in Figure 2, the utility model is welded in LED lamp on the ceramic lamp base to LED driving power and LED pipe, comprising: metal spiral shell 1, ceramic lamp base 2, metal film 3, some LED luminous tubes 4, bulb housing 8 and LED driving power.Wherein, ceramic lamp base hollow, the bottom has threading passage 5, peripheral groove 7 and two metal film solder joints 10.
Metal spiral shell 1 and ceramic lamp base 2 spin by screw thread, and the top of metal spiral shell is connected with sidewall with two metal film solder joints 10 and is connected.LED driving power and LED luminous tube 4 all are welded on the ceramic lamp base 2 by metal film 3, and bulb housing 8 is connected in the peripheral groove 7 of ceramic lamp base 2 bottoms.
As shown in Figure 2, the LED driving power comprises bridge heap 6, constant-current supply chip 9, resistance 11 and electric capacity; Electric capacity places in the ceramic lamp base 2, and an end links to each other with the output of constant-current supply chip 9, the negative output terminal of other end connecting bridge heap 6; Bridge heap 6, constant-current supply chip 9 and resistance 11 all are welded on the ceramic lamp base 2 by metal film 3, two inputs of bridge heap 6 link to each other with two metal film solder joints 10 respectively, the positive output end of bridge heap 6 links to each other with the input of constant-current supply chip 9, the output of constant-current supply chip 9 connects the positive pole of the LED pipe string that is composed in series by some LED luminous tubes 4, the adjustment terminating resistor 11 of constant-current supply chip 9, the negative output terminal of the equal connecting bridge heap 6 of negative pole of the other end of resistance 11 and LED pipe string, above-mentioned connection are all realized by the metal film 3 of burn-back on ceramic lamp base 2.
Alternating current joins from the metal film solder joint 10 that passes threading passage 5 and alternating current access after metal spiral shell 1 is drawn, and becomes the constant current drive current to constant-current supply chip 9 after heap 6 rectifications of passing a bridge, and driving LED luminous tube 4 is luminous.Electric capacity act as filtering, resistance 11 act as the adjustment continuous current.Pulsating current after the rectification is galvanic current.Bulb housing 8 is made by plastics or glass, can carry out diffuse reflection to the light that LED lamp group is sent, and makes it eliminate dazzle.The light that the lamp group is sent becomes soft through diffuse reflection.
Metal spiral shell 1 can be respectively E14, E26, E27, E40 type lamp holder as the power taking lamp holder, the heat that LED luminous tube 4 and constant-current supply chip 9 send, can directly be transmitted to metal spiral shell 1 by ceramic lamp base 2, be transmitted to again external environment condition, so thermal resistance is little, rapid heat dissipation.
The utility model is not construed as limiting the profile of bulb housing 8.
Among the existing LED, because LED driving power and LED are welded on the aluminium base, heat heat radiation approach has stopping of epoxy resin in the aluminium base or ceramic wafer, radiating effect is poor, and the utility model directly is welded in LED driving power and LED on the ceramic lamp base, and is both firm, and the capacity of heat transmission is strong again.The utility model directly adopts ceramic lamp base 2 as the carrier of heat radiation, LED luminous tube 4(LED lamp group) heat that produces directly is sent to metallic lamp holder 1 by ceramic lamp base 2, be sent to the outside lamp socket, metallic lamp holder 1 can power taking, can improve radiating effect again again.
Because temperature is higher than any object of Kelvin zero degree (273 ℃), infrared ray all can be arranged to locating radiant heat.At present, the far-infrared radiation material that is used in the high radiation coefficient of infrared source has metal oxide, and carbide waits object, and aluminium oxide ceramics is exactly fine a kind of.The material of the utility model ceramic lamp base 2 can be aluminium oxide ceramics, can Effective Raise heat loss through radiation ability.The integrated application of conduction, convection current and three kinds of heat transfer types of radiation makes the heat of LED obtain fine control.
The utility model is at the circuit of ceramic lamp base bottom sintering metal film 3, and directly source of welding current chip, power supply apparatus and LED manage or tube core on the adjacent metal film 3; There is little dead slot ceramic lamp base 2 inside, can run through power supply wiring; But ceramic lamp base 2 fixed light cell-shells 8.Adopt the utility model, the heat that power supply and LED produce passes through respectively the good heat loss through conduction of pottery and spiral metal lamp holder outside lamp socket and wire, also the ceramic lamp base louvre heat loss through convection through communicating up and down; The lamp holder exposed parts increases heat loss through radiation.The utility model is compared with existing LED bulb lamp, and the heat evolution of heat that has overcome power supply and LED generation will directly reject heat to lamp holder through the obstruction of the heat transfers such as aluminium base, so light decay is less, cost is lower, it is safer to use, is conducive to the application of LED lamp.
