Description

Novel flexible LED lighting device

Technical Field

The invention relates to the technical field of LED illumination, in particular to a novel flexible LED illumination device.

Background

In response to market demands, with the progress and development of the age, advertisers and commercial establishments often use neon lights to communicate information to the public on a commercial scale, which are well-known to the market and the public because of their bright, uniform, bright-colored and logo-like light distribution.

However, it is not easy to make a section of neon light, and the craftsman must first heat the lead glass tube, shape the tube to the desired shape, and then attach the electrodes to the ends of the lead glass tube. And the craftsman must also discharge the air and impurities in the lead glass tube and introduce inert gases such as neon, krypton, xenon, argon or helium. Finally, after each individual light segment of the neon light is formed, the craftsman must assemble the segments into a unitary structure, and then must connect 2 step-up transformers for each individual light segment, increasing the voltage from 120 volts to between 3000 and 15000 volts.

Compared with neon lights, the LED lighting is safer, and on the premise that a Light Emitting Diode (LED) converts electric energy into light with different colors, the LED does not need a transformer for raising the voltage above a dangerous level, and on the contrary, the LED only needs to work at a voltage of 3 to 24 volts. And the LED can be easily encapsulated in a variety of security materials and does not require the encapsulation of large fragile tubular lead crystal structures. And the brightness can still be responded very quickly and controlled easily, thereby realizing the visual effect which cannot be realized by neon lamps.

1. U.S. invention No. 7850341B2 discloses an elongated LED lighting device that provides an LED strip that simulates the characteristics of neon lights. The lighting device as a whole is flexible and can be bent into shapes, letters and other designs. However, once the plurality of LED modules are assembled by inserting them into the light guide plate, they are liable to slip due to tension generated during bending.

In addition, in another embodiment of the invention, the light guiding structure is rigid and requires extremely high heat to bend it; thus, the bending process cannot be completed in the field. Finally, one of the disadvantages of this invention is that it cannot be cut to match the length of the building's structural features or design parameters.

2. U.S. patent No. 10520143B discloses a structurally reinforced LED analog neon light. The invention provides stress relief for linear illumination in analog neon lamps. Further, the invention discloses a flexible covering having a translucent upper portion and an opaque lower portion. The cover is a flexible material that can be cut at specific points on the inside. However, this invention fails to disclose whether the remainder of the linear illumination can be reconnected for electrical connection.

3. U.S. patent No. 7604376B2 discloses a flexible peripheral lighting device that is an elongated flexible lighting system comprising an array of light sources disposed within an elongated translucent extruded flexible material. The defects of the 3 prior art are overcome. The invention provides a novel flexible LED lighting device which is different from the technical scheme.
