LED bulb light structure analysis
LED bulb light, like all the LED lamps and lanterns, with green environmental protection, health, energy saving, long Gao Liangshou, no stroboscopic, no mosquito advantages, is widely used in commercial and residential lighting market.
the composition of LED ball steep light
primary component of LED bulb light for: driver, lamp beads, lamp bead substrate, the radiator cover, PC, PBT, shell, lamp holder.
1 LED ball steep light driver
the first can be divided into: RC driver and IC driver
RC driven voltage shake scale is very narrow, in case of voltage is not stable, easy to burn. Scale of new light source can be used low voltage is 100 v - High voltage 130 v, size is 220 - 240V。 Low voltage too high will burn, will darken, stroboscopic.
the IC driver acceptable 10% voltage shake size, usually can use the low voltage size is 90 - High voltage 160 v, size is 160 - 260 v, no stroboscopic.
2 LED ball steep light the lamp bead used
according to the scale of 2835 and 5730 points first lamp bead
2835 lamp bead is refers to the scale of 3. 5 ( Long) × 2. 8 ( Wide) × 0. 8 ( Thick) Mm LED lamp bead, generally 3 w LED bulb light each 2835 lights, power is zero. 2 w, 9 w, 12 w LED bulb lights each lamp bead power 2835 to 0. 5W。
5730 lamp bead is refers to the scale of 5. 7 ( Long) × 3. 0 ( Wide) × 0. 8 ( Thick) Mm LED lamp bead, generally 5 w, 7 w LED bulb lights each lamp bead the power of 5730 to 0. 5W。
than 5730 lights, the brightness of the 2835, the comprehensive function such as better heat dissipation, 2835 in the LED industry has become the bulb, the ball bubble lights, panel lights, and other lamps and lanterns to specify selection of LED lamp bead.
3 LED ball steep light lamp bead substrate
the first divided into bo qian plate and aluminum plate
glass fiber board: selection of glass fiber cloth, low cost, high pressure resistance, but poor heat dissipation.
aluminum plate, with a special kind of metal base copper-clad r. p. panel and good function of thermal conductivity, electrical insulation function is poorer, the high cost.
in high-grade LED ball steep light will choose high quality aluminum substrate.
4 LED ball steep light radiator
that aluminum radiator cover
LED bulb light plastic bag was used for the aluminum structure, fully combined with plastic insulation, corrosion resistance and thermal conductive metal aluminum quick characteristic, coupled with the unique structure of air convection, makes the heat dissipation is more agile and ensure the full cut droop.
5 LED ball steep light shade
common cover a milky white, transparent cover on the market two kinds, the material such as PC, glass, ceramic, silica gel.
now, LED ball steep light shade number best PC cover, range 85 ~ 90%, the uniform and soft light, of course the price also is the most expensive.
6 LED ball steep light shell
generally choose insulation PBT, shell, has the very good insulation and corrosion resistance.
7 LED ball bubble lamp, lamp holder
LED bulb light to replace the general incandescent lamp, the lamp holder of practice with E27, E14, can also be completed the specification of the lamp holder tailored for different countries.
