54 results about "Rope light" patented technology

A rope light is primarily used as a decorative lighting fixture, featuring small light bulbs linked together and encased in a PVC jacket to create a string of lights. Rope lights can be used in many applications both indoors and outdoors. Used in place of neon signs, it is sometimes called soft neon.

Resin composition and method for preparing FPC coverlay by using same

The invention relates to a resin composition and a method for preparing an FPC coverlay by using the same. The resin composition comprises the following components in part by weight: 50 to 70 parts of flexible saturated polyester, 30 to 50 parts of hard saturated polyester, 1 to 20 parts of enclosed isocyanate curing agent, 15 to 150 parts of pigment, 15 to 120 parts of inorganic filler, 0.5 to 2.5 parts of antifoaming agent, and 5 to 30 parts of organic solvent. The resin composition is applied to the FPC coverlay in a flexible printed circuit. The resin composition has the characteristics of excellent weather resistance, high covering power, high flexibility and adhesiveness, and the like. The method for preparing the FPC coverlay by using the same can realize the one-off coating of the FPC coverlay on the flexible printed circuit, has the advantages of simple manufacturing method, low cost and high yield, and can realize the continuous production and obviously improve the production efficiency. The FPC coverlay produced by the method can improve the contrast ratio of an LED rope light under the action of an insulating base film besides excellent dust prevention, corrosion resistance, weather resistance and other characteristics.

Flexible rope light

The invention discloses a flexible rope light, which comprises a flexible core wire, a light string arranged in the core wire, and a flexible transparent coating layer which coats the core wire and the light string. The flexible rope light is characterized in that: the light string comprises a plurality of chip LEDs which are connected through a conductive wire, and the light string is also connected in series with a current-limiting resistor; a first main power cord and a second main power cord serving as the main power cords are arranged on two sides of the core wire; a power plug and a power extension head which are electrically connected with the first main power cord and the second main power cord are arranged at the head end and the tail end of the flexible transparent coating layer; and the sum of the rated voltage of the plurality of chip LEDs and the resistor is equal to the input voltage of the rope light. By replacing the traditional flexible circuit boards by adopting a metal strip and the conductive wire, the flexible rope light can be applied to high-voltage drive, and the number of the chip LEDs is reasonably adjusted according to the input voltage of the rope light. Therefore, a switch power supply is saved, the manufacturing cost of the rope light is greatly reduced, and the length of the rope light is prolonged.
