Closed LED lamp strip made of light-transmitting adhesive film and manufacturing method of closed LED lamp strip

Abstract

The invention relates to a closed LED lamp strip made of a light-transmitting adhesive film and a manufacturing method of the closed LED lamp strip. The manufacturing method of the closed LED lamp strip particularly includes the following steps of: manufacturing a single-sided or double-sided circuit board; welding components containing LED lamps on the front surface of the circuit board by an SMT; applying a light-transmitting adhesive on the light-transmitting film; manufacturing the coated light-transmitting film into a light-transmitting film containing multiple cups; arranging the light-transmitting film cups on the component surfaces of the circuit board in an aligned manner with the cups facing downwards, covering each component with the corresponding cup; slitting the circuit boardinto single strips by using a slitter; and manufacturing the single strips into closed LED lamp strips made of the light-transmitting adhesive film. With the closed LED lamp strip of the invention adopted, the technology that an adhesive is dripped onto an LED lamp strip in the industry at present to realize a water-proof effect can be replaced. The LED lamp strip can be wrapped with an adhesiveor a sleeve to realize a water-proof effect; the LED lamp strip is low in cost; a plurality of lamp strips are manufactured and produced together through a spliced board, and therefore, the productionefficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a closed LED light strip made of light-transmitting adhesive film and a manufacturing method thereof. Background technique [0002] Nowadays, waterproof LED strips in the industry are usually waterproofed in the following two ways. One is to drip glue on the front cover film of a single LED strip circuit board and soldered components to form a layer The thick glue layer is much higher. This method consumes a lot of glue, and the front of the light strip circuit board must be covered with high-temperature-resistant and expensive PI to protect the circuit from being easily broken, resulting in high material costs. In addition, the production efficiency of a single operation is very low. Low. [0003] Another method is to waterproof a single LED light strip by encapsulating or wrapping a tube. In this method, the circuit board of the light strip must be covered with high-temperature-r...

[0003] Another method is to waterproof a single LED light strip by encapsulating or wrapping a tube. In this method, the circuit board of the light strip must be covered with high-temperature-resistant and expensive PI to protect the circuit board. In addition, the material cost of the rubber or casing is high, and the production efficiency of a single operation is very low
