The plasticity of LED gives lighting a great imagination space, and LED light bulbs are also very subdivided, that is, specific light bulbs have specific uses. Today we will talk about light bulbs.
First of all, let's understand the common civilian lamp sockets: E14, E27, E40, B22, G4, G9, etc., where E is the screw, the number is the diameter of the thread, B is the bayonet, and the number is the screw shell bayonet The diameter of , G is the plug-in lamp head, the number is the center distance of the two pins, the E40 lamp head is often used for outdoor lamps, and the others are basically used indoors.
Light bulbs can be roughly divided into: 1. Basic lighting type: Basic lighting bulbs are mainly used for lighting to improve brightness. 2. Decorative lighting type: Decorative lighting type bulbs are used in conjunction with lighting to create a better lighting atmosphere and enhance lighting art. 3. Specific function type: other specific function bulbs.

3. LED corn bubble bulbs

The shorter the connection between the lamp head and the light-emitting area, the better the effect, so that the lampshade of the chandelier can realize no dark area. The common power is 10-16W, and the common color temperature: positive White, warm white, neutral.
2. Suitable for chandeliers (the bulb is exposed to the lampshade)
