This time we introduce the performance of fully-filled LED soft strip lights. The original LED step lights used sleeved LED soft strip lights and LED glue strip lights. These two models are known in the industry as having an IP65 rating, but this approach is not recommended for use in outdoor engineering cases or LED landscape cases. Difference description: A.LED sleeve soft strip lights are actually composed of bare board + silicone sleeve, achieving dustproof and waterproof. 1. When the LED is hit by a frontal impact, the silicone sleeve is soft and does not protect the internal LED. 2. The inlet end of the casing must be properly protected to avoid water intrusion due to pulling and rupture after construction. 3. When the waterproofing of the on-site wiring is poor, water or moisture will penetrate the copper wire's cooling and heating effects, causing siphonage and water intrusion. B. LED glue strip lights are covered with a layer of PU glue on the exposed LED board to achieve dustproof and waterproof on the front. 1. The main disadvantage of the LED flexible strip light is that the back is not waterproof Outdoor lighting mainly depends on the quality of the product itself + the quality of on-site construction to extend its service life. Factory customization Recommended length: DC24V length 20 meters double-ended power supply, DC12V length 10 meters double-ended power supply Color temperature range: 2700K ~ 6500K Power range: 5W ~15W/meter, single row Waterproof level: IP68 Outlet method: 2 wire length < 10 meters Leave a waterproof layer on the front and back of the PCBA LED soft board, and tightly cover the LED and soft board. The wires are also wrapped in adhesive material, and the outer layer has a heat-shrinkable sleeve to enhance waterproofing and reduce the pulling force that may cause the adhesive material to break. After learning about the product, go to the construction site to see actual performance. Removing glue from lamp power wiring hole cover Clear the original LED glue strip lights and LED tube soft strip lights operations, Site bonding requires silicone to reinforce waterproofing Use a scraper to remove it and it will almost become crispy! Removing old silicone takes a lot of time!! Take out the arrangement position of LED soft strip lights Peel off the 3M adhesive on the back and press along the edges to fix it! After pressing, apply glue to the power hole. The 3M adhesive tape is only for temporary fixation. In actuality, the upper and lower edges of the LED flexible strip lights and the joints with the wall must be firmly covered with a layer of glue to prevent them from falling off.

LED Panel light product description:

Since the development of LEDs, chip efficiency has continued to increase and prices have continued to decline. LED flat lights are divided into two categories, with lower cost, commonly known as direct lighting. This type of assembly and production is similar to the practice of advertising boxes, and the higher cost is the side emitting light guide type. , This article introduces the specifications and details of our company's panel lights in detail.

3. The thickness is about 10mm and the weight is about 3.5 kg.

shortcoming:

1. The design structure is more complicated and the material cost is high

2. The center of the LED will gradually become darker when used for more than 50,000 hours.

2-1Minor specifications of direct light and side light panel lights:

1. The LED grade and quantity are different, under the condition of 2x2 feet (60x60cm):

A. The selection range of direct light-emitting LEDs is SMD2835 as the mainstream, and the number of LEDs used is

From 48pcs, 64pcs, 108pcs, 144pcs, 192pcs... etc., the brightness of series and parallel is different to match the power supply.

B. Side-emitting LED selection restrictions SMD5630, SMD2835 are the mainstream. The number of LEDs used,

Only 120 and 192, the brightness of series and parallel is different to match the power supply.
