Description

LED lighting with reinforced water-proof function

The present invention relates to a lightweight LED luminaire with enhanced waterproof, and more particularly, an environment continuously exposed to moisture such as a fishing lamp installed outdoors or a fishing boat such as a street lamp. In constructing the LED luminaire used in the LED, the back cover is directly bonded to the circuit board on which the LED is mounted, so that the weight of the LED is significantly reduced so that it can be handled more easily. The waterproof packing for electric wires formed according to the thickness of the wire can be installed without using a separate pressure device, so that even if it is used for a long time in the state of being exposed to moisture, the waterproof function prevents salt and moisture from entering the luminaire. Reinforced lightweight LED luminaires.

In general, led fish-luring lamps are rapidly developed due to the active heat dissipation design, research on preferred wavelengths of fish species subject to daylighting, optical lens design, research projects through demonstration ships, and fishery equipment improvement projects. As it is widely used, the waterproof design for increasing the life of the LED luminaire in the harsh marine environment is becoming important.

Meanwhile, in order to prevent moisture from penetrating into the luminaire in the configuration of the waterproof type LED luminaire, it is common to apply liquid silicone to the coupling portion of the circuit board and the back cover, which is a contact surface portion that may be in contact with moisture.

However, the liquid silicone applied to the bonding portion of the circuit board and the back cover in this way requires about 24 hours of curing time at room temperature, and the application of the liquid silicone can be easily performed, but the liquid After application of silicone, disassembly or reassembly is impossible, and it is inevitable that water is not completely waterproof because micro spaces are formed in the liquid silicone working part that is applied after the removal of liquid silicon during rework for repair. there is a problem.

In addition, due to the characteristics of the waterproof LED luminaires, waterproof inspection is performed after assembly.The curing time of liquid silicone takes a long time, so it is not competitive to produce the product. Even in the case of good quality products that have undergone the process, in the marine environment, the waterproof function is gradually lost due to deformation due to strong waves, salinity and temperature difference, which causes secondary failure of the LED luminaire.

When salt is penetrated due to poor waterproofing, it causes corrosion of LED elements, internal wiring, and soldering parts, resulting in total failure of LED lighting fixtures, resulting in a huge loss in post-management costs.

In order to solve such a conventional problem, various technologies have been developed, and as an example, Korean Patent Publication No. 10-1658460 (name: waterproof LED lighting device, hereinafter referred to as 'prior art') has been proposed. .

Substrate seating grooves are formed in the lower side of the inner wall in the longitudinal direction of each frame, and a light guide plate is formed at one side of the board seating groove. A seating part is formed to protrude to a certain height, and one side of the light guide plate seating part is formed such that a diffusion plate seating part has a cross-sectional shape of “┗”, and a screwing groove is formed at the other side of the board seating groove, The heat sink is protruded outwardly in the form of a flange, the silicon groove is formed in the groove in the longitudinal direction so that the cross section is semi-circular at a certain point of the frame where the lower edge of the diffusion plate and the cover member abuts Is the gist of the technical configuration.

However, the above-described prior art has a problem in that its structure is very complicated, so that its weight is high, so handling is inconvenient, and it is difficult to apply to an LED luminaire which is applied to a street lamp or a pick up lamp.
