The composition of LED bulb
1.2 Lamp beads used in LED bulbs
According to the size, there are mainly 2835 and 5730 lamp beads 2835 lamp beads refer to LED lamp beads with a size of 3.5 (length) × 2.8 (width) × 0.8 (thickness) mm. Generally, a 3W LED bulb lamp has a 2835 lamp bead power of 0.2W, 9W, 12W LED bulbs. The power of each 2835 lamp bead is 0.5W. 5730 lamp beads refer to LED lamp beads with a size of 5.7 (length) × 3.0 (width) × 0.8 (thickness) mm. Generally, the power of each 5730 lamp bead for 5W and 7W LED bulbs is 0.5W. Compared with 5730 lamp beads, 2835 has better overall performance such as brightness and heat dissipation. In the LED industry, 2835 has become the designated choice for lamps such as lamp tubes, bulb lamps, and panel lights.1.3 The lamp bead substrate of the LED bulb
Mainly divided into glass solder plate and aluminum substrate Glass fiber board: It is made of glass fiber cloth, which has low cost, high pressure resistance, but poor heat dissipation. Aluminum base plate: It is made of a special metal-based copper clad laminate, which has good thermal conductivity, poor electrical insulation performance, and higher cost. Medium and high-end LED bulb light basically use high-quality aluminum substrates.1.4 Radiator of LED bulb
Radiator is aluminum cover LED bulbs are made of plastic-clad aluminum structure. This fully combines the characteristics of plastic insulation, corrosion resistance, and fast heat conduction of metal aluminum, coupled with a unique air convection structure, which makes heat dissipation faster, guarantees life, and reduces light decay.1.5 Shade of LED bulb
There are two common types of milky white cover and transparent cover on the market. The materials are PC, glass, ceramic, silicone, and so on. Nowadays, the number of PC covers for LED bulbs is the best, with 85~90% light transmittance, uniform, and soft light, and of course the most expensive.1.6 Shell of LED bulb
Generally, you use insulated PBT shell, which has good insulation and corrosion resistance.1.7 The base of the LED bulb
LED bulbs can replace ordinary incandescent lamps. The conventional lamp holders are E27, E14, and can also be customized for standard lamp holders in different countries.-
