A lighting device comprising a sealed transparent flexible outer tube having a handle at a first end. The handle includes a power source. Inside the tube is a flexible wire extending from and attached to the handle. The wire extending the length of the outer tube. Also inside the tube are multiple small lengths of inflexible interior tubing running at least a partial length of the flexible outer tube. Each interior tubing having at least one light emitting diode and at least one resistor inside. The resistors and diodes are connected electronically to a circuit board and the power source.

The invention discloses an LED module repairing device, which comprises a clamping base, a calibration table and a maintenance device; wherein: the clamping base is used to fix and carry a faulty LED module and the calibration stage; the calibration stage It is used to send the maintenance device to the faulty lamp bead of the LED module; the maintenance device is fixedly installed on the calibration table, and is used to generate hot air and transport it to the LED module, so that the welding of the The solder of the faulty lamp bead on the LED module is melted, and the faulty lamp bead is removed by adsorption. Through the embodiment of the present invention, the entire device has a simple structure and simple operation, simplifies the maintenance work of the LED lamp surface, and reduces the maintenance workload and maintenance cost.

The invention discloses an LED module maintenance system, which includes a clamping base, a correction table, a lamp changing device, a material conveying device, and a pneumatic device; wherein: the pneumatic device provides an air source for the lamp changing device and the material conveying device; the clamping base is fixed It carries the faulty LED module and the calibration table; the calibration table sends the lamp replacement device to the faulty lamp bead of the LED module; the lamp replacement device generates hot air and conveys it to the LED module under the air suction of the pneumatic device, so that the welding LED The solder of the faulty lamp bead on the module is melted, and the faulty lamp bead is adsorbed and removed; and the replacement lamp bead is adsorbed from the conveying device and placed at the disassembly point of the faulty lamp bead; the material conveying device is set on the clamping base, and the The pneumatic device is inflated and sucked to move down to the right below the lamp replacement device, accepting the lamp replacement device to absorb and remove the faulty lamp beads and transporting the replacement lamp beads to the bottom of the lamp replacement device. Through the embodiment of the present invention, the system structure is simple, the operation is convenient, the maintenance work of the LED lamp surface is simplified, and the maintenance workload and maintenance cost are reduced.

Apparatus and methods are disclosed which may keep retractable landscape lamps substantially free from water intrusion in operation for a variety of embodiments. Retractable lamps may have a lower fixed portion which could be buried in the ground and an upper portion which may rise and illuminate. When the upper portion rises it may create a low pressure or vacuum inside. Water may be pulled into the lamp which may lead to failure. The lamp may benefit from a seal between the lower and upper portions. A seal may consist of a flexible rubber material and a grease or other lubricant which may form a watertight seal with low friction. The upper portion may have a cap with provisions for aspiration. While traveling between the retracted and extended positions the lamp may aspirate through the bottom of this cap. The cap may be designed to trap an air reservoir when it retracts. It may then provide air for aspiration the next time the lamp rises to permit such a rise such as above wet conditions or above standing water. The cap may have a protective vent which may allow air to pass while restricting water from passing.

The embodiment of the present invention provides a device and method for LED screen light point fault detection, the device includes: a light point control module, used to control each light point included in the LED screen in a predetermined order and their corresponding The light-emitting rules send out light wave signals in sequence, and the light-emitting rules are compiled according to the light-emitting mode of each light point of the LED screen and the unique identification code corresponding to each light point; the signal receiving and processing module is used to receive the light wave signal sent by each light point , to decode the light wave signal to obtain an effective identity restoration code; the fault point determination module checks the duplicates in the standard database according to the effective identity restoration code, and will not be able to find the valid identity restoration code corresponding to the overlapping identity identification code in the standard database The corresponding light point is determined as a faulty light point; the fault information generation module is used to send fault information according to the faulty light point and its corresponding identification code. This embodiment can accurately and efficiently detect lamp failures.
