The specific embodiment
Below in conjunction with accompanying drawing, the utility model is explained in further detail.
As shown in Figure 1, the structure of a kind of LED filament bulb of the utility model as shown in Figure 6, LED filament post, driving power, Glass lamp column holder, glass envelope, several parts of standard lamp head handware, consisting of, is all device cheaply, can produce the par LED lighting that popular illumination needs.
As shown in Figure 2, N low power LED tube core is directly encapsulated on glass column substrate.Such as by the 1016 LED die package of 28 every 0.02W on the glass column substrate of long 38mm, diameter 1.5-1.6mm, adopt gold thread series connection.VF=3.2X28=89.6V, the IF=10mA of this LED filament post.The maximum feature of LED filament post is that 360 degree full angles are luminous, adopts high voltage (75-90VDC), little electric current (10-15mA) to drive duty; Adopt high-quality LED tube core can produce the LED filament post of high brightness (75-95lm), high light efficiency (120-130lm/W), high color rendering index (CRI) (90-95Ra), high reliability; Blue and red LED tube core is mixed and takes the LED filament post that can produce different-colour (2870-6020K) in different ratios.
As shown in Figure 3, the blueness of packaged LED on glass column substrate+red tube core, regularly arranged by presetting, two ends arrange electrode pin, after gold thread series connection, spraying yellow or yellowish green fluorescent material, all outer adhesive layers of wrapping up in.
During energizing test, to note high-tension protection.This class LED filament post is little electric current, the small-power state that is operated in 10-15mA, and whole LED filament post, in unsettled comprehensive engagement inert gas, dispels the heat unimpeded, generates heat very low, does not substantially scald.
The LED bulb lamp that the utility model utilizes LED filament post to design various middle low powers is very easy.Take candle lamp as example, and two LED filament post series connection just can be designed to the luminous 1.8W candle lamp of 360 ゜, and luminosity can be equivalent to the incandescent lamp of 8-10W.Two and four LED filament posts of two strings just can be designed to the luminous 3.6W bulb lamp of 360 ゜, and luminosity is equivalent to the incandescent lamp of 22W.Any incandescent lamp factory all can utilize prior art and streamline to produce LED filament bulb lamp, utilizes the connection of the original glass supporter design of incandescent lamp LED filament post; Utilize the printing opacity of incandescent lamp to cross the special glass that rate is high, with automatic glass-blowing ball bubble production technology, the ball bubble-cap exactly like incandescent lamp is produced in design, thus can the good LED filament bulb lamp of production cost performance, and be quite subject to market favor, the good glass decoration light fixture of new generation of profit.
The selection of driving power.LED light source must drive with Constant Direct Current electric current, could stabilized illumination and flicker free.Unisolated switch constant-current source is selected in the selection of driving power, and its advantage is that efficiency is high, and PF is also good, and chip integration is high, and application circuit is succinct.As BP2831/2832, functional integration is high, and built-in MOSFET has higher PF value, application circuit is very simple, and the former number of devices of periphery only has 14, and reliability is higher, has excellent line regulation, load regulation, can be by conduction and radiation, the area Φ 25mm of pcb board.
