The decoration method of the original Christmas lamp manufacturer is to install a special flash bulb at any position of the lamp string, and the additional metal sheet on the top is a bimetallic sheet, through which the current enters the connecting column to light the filament. This process is repeated repeatedly; Now there are more complex bulbs, which have 16 function controllers, which can control the bulbs according to various interesting patterns. Ventilation found that the control box that drives four independent mini lamp strings is staggered, and the structure includes an integrated circuit, four transistors or three terminal bidirectional thyristor switch, one switch drive and one lamp string.

Guide for installation and use of Christmas light bar
1.Indoor installation: when Christmas lights are used for indoor decoration, the installation is very simple because they do not have to withstand the wind and rain.
2. Outdoor installation: outdoor installation will be exposed to wind and rain. If 3M glue is used for fixing, the stickiness of 3M glue will be reduced over time, resulting in the fall off of Christmas lights. Therefore, outdoor installation often adopts the method of card slot fixing. Where cutting and connection are required, the method is the same as that of indoor installation, but waterproof glue needs to be additionally equipped to consolidate the waterproof effect of the connection point.
3. Power connection method: the general voltage of Christmas lights is DC 12V, so switching power supply is required. The size of the power supply is determined according to the power and connection length of Christmas lights. If you don't want each Christmas lamp to be controlled by a power supply, you can buy a high-power switching power supply as the main power supply, and then connect all the Christmas lamp input power supplies in parallel (if the wire size is not enough, it can be extended), which is uniformly powered by the main switching power supply. The advantage of this is that it can be controlled centrally. The inconvenience is that the lighting effect and switch control of a single Christmas lamp cannot be achieved. The specific method can be measured by yourself.
