- the soft surface 72 can ensure the flexibility of the flexible LED lamp, that is, the soft surface 42 has sufficient flexibility, that is, when the flexible circuit board layer 10 is bent, the soft surface 72 can ensure The functional layer 70 does not deviate from the flexible circuit board layer 10.
- both the nylon fabric and the TPU film have a wide flexible holding temperature, and the nylon fabric can be damaged between -40 degrees Celsius and 50 degrees Celsius and It still has a high degree of flexibility, which in turn allows the flexible LED luminaire to be used in a complex and variable environment.
- the waterproof layer 73 on the functional layer 70 is implemented as a water repellent coating, that is, on the soft surface
- the bottom layer of 72 is coated with a material having a waterproof function to form the waterproof layer 73.
- the waterproof layer 73 can place moisture from the non-working surface 12 of the flexible circuit board layer 10 to break the normal operation of the flexible circuit board layer 10.
- the step 5 further includes the following steps: 5000.1: forming a soft layer 72;
- 5000.2 forming an adhesive surface 71 on the top surface of the soft layer 72;
- a waterproof layer 73 is formed on the bottom surface of the soft layer 73, wherein the bonding surface 71, the soft layer 72 and the waterproof layer 73 collectively form the functional layer 70.
- another object of the present invention is to provide a flexible LED lamp and a method of manufacturing the same, wherein the manufacturing method of the flexible LED lamp is easy and easy to operate, and the manufacturing efficiency of the flexible LED lamp can be greatly improved.
