Description

Flexible LED silica gel lamp area of even luminous

Technical Field

The invention relates to the technical field of lamp belts, in particular to a flexible LED silica gel lamp belt capable of emitting light uniformly.

Background

The LED silica gel lamp strip is a lamp commonly used for indoor and outdoor decorative lamps, and is applied to night scenes, water scenes and greening lamplight. Because the flexible circuit board FPC, PCBA and the like are adopted and extruded out of the elastic silicon rubber material by the hot vulcanization glue to be integrally formed, the LED lamp strip has better waterproof and sealing performances compared with the old silica gel sleeve LED lamp strip. The lamp strip has the advantages that the circuit board is adopted to be in no air contact with silica gel and is not easy to oxidize, so that the service life of the lamp strip is relatively long, a group of light-emitting lamp sources are arranged on the flexible circuit board, when one or more light-emitting lamp sources in a group break down, the problems of dim light and dim light can occur, although the normal work of the light-emitting lamp sources is not influenced, the brightness and the whole attractiveness can be influenced, generally, the lamp strip can be integrally taken out of the silica gel for maintenance, the whole installed silica gel lamp strip needs to be taken out completely, and the rubber sleeves can be sleeved at two ends through glue to prevent dust from entering and water from entering.

For example, patent application No. cn202111375388.X, specifically, a silica gel lamp strip with uniform light emission, which has a structure that, by reflecting a distance, performs optical reflection and light diffusion effects on light emitted from LED lamp beads, so that the emitted light of the lamp strip is more and the illumination is more uniform; the side of flexible line way board is equipped with the bump for LED lamp pearl keeps suitable reflection distance with soft lamp area gluey inslot wall all the time, the photochromic of the light-emitting that makes soft lamp area after any bending deformation keeps even, and go out the plain noodles and do not have the shadow and keep soft lamp area light-emitting even, but the lamp area still is as an organic whole, and luminous lamp pearl also is a set of, consequently, lamp pearl just need wholly take out after breaking down, then again through taking out the gum cover from the silica gel both ends, can take out lamp area wholly, lead to the dismouting troublesome, and after unable maintenance, can only carry out whole replacements to whole lamp area, lead to the big and extravagant problem of replacement cost.

For another example, patent application No. CN202022722854.4 specifically is a LED silica gel high pressure soft lamp area, its structure uses the copper line as the mode of soft lamp area power transmission, adopt flexible PCB board front face to arrange electronic component, the flexible PCB board bottom sets up the power transmission line that the copper foil strip was regarded as the soft lamp area, its volume that has effectively reduced the soft lamp area, the range of application and the result of use in soft lamp area have been improved, but the lamp area also only has a set ofly, consequently, after the light-emitting lamp source breaks down, can only carry out the problem of maintaining after overall change or the overall dismantlement.
