When LED lamp power is big, can open some sidewall louvres 4 on the sidewall of ceramic lamp base 2, sidewall louvre 4 communicates with dead slot 5.
As shown in Figure 5; Power supply 6 comprises some groups of power circuits, and each power circuit comprises a capacity voltage dropping circuit that is composed in parallel by capacitor C 1 and resistance R 1 18, a rectification circuit 19 and a filtering current-limiting circuit 20 that is composed in series by capacitor C 2 and resistance R 2 of being made up of four diode D1-D4; Capacity voltage dropping circuit 18, rectification circuit 19 and filtering current-limiting circuit 20 link to each other successively.The other end of capacity voltage dropping circuit 18 links to each other with the AC power (not shown), filtering current-limiting circuit 20 other ends through lead be welded on potsherd silver foil circuit 14 and link to each other with luminous component 9 on the ceramic lamp base silver foil circuit 10.
AC power 17 (not shown)s are through the step-down of capacity voltage dropping circuit 18, and the rectification of rectification circuit 19 becomes direct current stably after the filtering of filtering current-limiting circuit 20 and the current limliting, and driving LED is luminous.Wherein, capacity voltage dropping circuit 18 is made up of R1 and C1, and C1 is a decompression capacitor, plays step-down and metering function, and R1 is a bleeder resistance, residual charge on the electric capacity of releasing; Rectification circuit 19 is formed bridge heap by D1, D2, D3, four commutation diodes of D4, and purpose is to be AC rectification direct current; Filtering current-limiting circuit 20 is made up of C2 and R2, and C2 act as filtering, and R2 act as current limliting, and making the pulsating current after the rectification is that galvanic current supplies LED lamp group 21 luminous.
The electric current of power supply 6 outputs is through luminous component 9 power supplies of through wires hole 15 to potsherd silver foil circuit 14 and ceramic lamp base silver foil circuit 10; Bulb shell 13 is processed 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, and luminous component 9 evolutions of heat on it can be transmitted to the outside lamp socket again through being transmitted to metal spiral shell 1.
The sidewall louvre 4 of ceramic lamp base 2 communicates with the external world, and bottom louvre 8 communicates through dead slot 5 with sidewall louvre 4, and making luminous component 9 produce heat can be through bottom louvre 8 and sidewall louvre 4 heat loss through convection.
Luminous component 9 mutual vertical installations on luminous component 9 on the potsherd silver foil circuit 14 and the ceramic lamp base silver foil circuit 10; LED level on the potsherd silver foil circuit 14 is luminous; And the LED vertical light-emitting on the ceramic lamp base silver foil circuit 10; The light that sends like this replenishes each other, and it is omnibearing luminous to form facade.
Embodiment 2
As shown in Figure 2, this embodiment 2 only is that with the difference of embodiment 1 potsherd 11 has 3, evenly is weldingly fixed in the middle of ceramic lamp base 2 bottoms through 6 metal connecting sheets 7; Like this, be welded on these potsherds 11 to such an extent that the light that sends of luminous component 9 replenishes each other, more even, it is omnibearing luminous to form facade.In fact, can select the sheet number of potsherd 11 to satisfy real life production needs arbitrarily, the utility model does not limit the sheet number of potsherd 11.
Embodiment 3
As shown in Figure 4, this embodiment 2 only is that with the difference of embodiment 1 among this embodiment, bulb shell 13 is a candle lamp formula bulb shell.In fact, can select the shape of bulb shell 13 to satisfy real life production needs arbitrarily, the utility model does not limit the profile of bulb shell 13.
Among the existing LED; Because aluminium base and radiator bond through heat-conducting glue, what heat heat radiation approach had epoxy resin and a heat-conducting glue in the aluminium base stops that their thermal conductivity factor is respectively 0.2W/mK and 1W/mK; Radiating effect is poor; And the utility model adopts ceramic lamp base 2 and potsherd 11, and its thermal conductivity factor is 24W/mK, and the capacity of heat transmission is strong; In addition, all be direct welding between luminous component, ceramic lamp base 2, the potsherd 11, not only thermal resistance is little, and firm.The utility model adopts the carrier of pottery as heat radiation, and the heat that LED lamp group is produced directly is sent to metallic lamp holder through pottery, is sent to the outside lamp socket again, and lamp holder can power taking, again abundant good heat dissipation effect; Because ceramic lamp base 2 all has louvre up and down, be beneficial to heat and discharge in addition.
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.And the far infrared radiation rate also increases (radiance refers to compare with the black matrix with condition) with the raising of temperature, and the radiance in the time of 25 ℃ is about 80%, reaches about 90% when bringing up near 90%, 100 ℃ in the time of 50 ℃.The utility model adopts aluminium oxide ceramics just can effectively improve heat-sinking capability.
The LED that processes at present is generally single face and installs, and the bulb lamp of making is can only the latter half luminous, and this patent is owing to adopt the multiple channel heat radiation; Needn't utilize the outer cover of aluminium, volume is little, and adopts the plastics or the glass of printing opacity; Lighting angle is increased greatly, not only reduce cost, and pottery and the outer cover that insulate; Use safer, simultaneously power can do bigger, help the popularization and the application of LED lamp.
