Shenzhen Longgang LED wall washer LED wall washer colorful outdoor lighting factory outlets

Brand: Guangyuan macro lighting Model: GYH-XQD-024 Input voltage: 220 (V) Luminous flux: 24 (LM) Color Temperature: 4000 (K) CRI: 85 LED lamp bead quantity: 24 Shell material: Aluminum Beam angle: 120 (degrees) whether dimming: No Size: 1000 * 63 * 63 Operating temperature: 45 Life: 50,000 Protection: IP65 Light Color: Warm white, white, color, warm white, white, colored Power: 24 ( W) LED wall washer structure and routine testing 1. LED wall washer structure of the power module installed inside the housing, limited space, some manufacturers in order to save space, the pin-like element surface welding in the PCB, this approach is not acceptable. The surface of the welded pin-elements are likely to fall due to the Weld and other reasons, dangerous. So for these elements to take Jack welding possible. If you had to take surface welding, we have this piece and glue components using fixed, etc. to provide additional protection. 2. Test temperature rise test is a must-do product safety testing, standards for different elements have certain temperature limits. In the product design stage manufacturers to attach great importance to heat the products in question, especially for some components (such as insulating films, etc.) should pay particular attention. Member if long-term work in high temperature conditions, easily damaged, resulting in a fire or electric shock hazard. Inside the lamp power supply module is enclosed in a small space, cooling is limited. Therefore, the manufacturer component selection, pay attention to choose the specifications appropriate elements ensure that the component at a certain margin work, in order to avoid long-term work element at near full load conditions arising from overheating. 3. Aging test LED wall washer factory production, the need for LED wall washer carried about 24 hours of aging test, waterproof test should be completed immediately after the aging test! 4. Water testing water testing should be completed during the burn-in test of a test project immediately. So as to simulate the real environment test the LED wall washer's IP protection. This approach is generally known as thermal measurement! After the lamp to shine the light will be a phenomenon of thermal expansion and contraction, this time to really test out the test LED wall washer in the case of outdoor harsh environment's ability to perform it! Guaranteed under the wind and rain and sun lamps, etc. There is no question of its waterproof and dustproof capabilities 5. Fault detection and fault testing product certification testing is a crucial test project. This test project is shorted or open some elements of the line, in order to simulate actual use failure may occur, in order to assess the product under a single fault condition safety. To meet this safety requirements, product design, consider the input of the product plus the appropriate fuse, to prevent output short circuit or over current internal component failure causing a fire risk. LED wall washer LED wall washer principle because the volume is relatively large, the heat better, so in terms of design also greatly reduces the difficulty, but in practice, there will be constant current drive is not doing too good, appear damaged lot, so how to be able to better run, the focus on the control and drive aspects, control and driver side, let us work together to learn about LED constant current is related to the high-power LED products, we will mention to the constant flow-driven, and that what is LED constant current drive it? Regardless of load size. The changes in the LED current to maintain constant LED constant current drive circuit is called. If the inside wall washer and must be 1W of LED, we usually 300MA constant current LED driver with constant current LED driver purpose is to improve the life of the LED and the light fades. The quality of the constant current source selection is based on their efficiency and stability, I choose as high efficiency constant current source, thus reducing energy consumption. LEDL Let us analyze the main wall washer applications and can achieve the effect of LED wall washer control through the built-in microchip, in a small engineering applications, you can not control use, to achieve a gradual, transition, color blinking, random blinking, alternating gradient and other dynamic effects, it can control by DMX achieve chase, scan results. LED wall light wall washer safe use of either a single installation, or you can combine multiple lamp centrally installed on more than 20m pole, constituted high pole lighting. This means in addition to attractive appearance, centralized maintenance can reduce poles and footprint characteristics, the biggest advantage is the powerful lighting. When the light shone down from a height, the space environment high brightness, large coverage, giving a feeling similar to daylight, so there is a high lighting quality and visual effects. In order to meet the minimum safety requirements for outdoor use, wall lamp enclosure class should be IP × 3 (open). To improve the durability of the lamp, reducing maintenance workload, there is growing emphasis on the development of a one-time investment costs higher closed wall washer, its enclosure protection class IP65. In order to further improve lighting light output ratio reflector tends to help reduce the use of the light source stopper plate surface reflector and meet multifocal reflector special lighting requirements; Surface treatment reflecting surface tend to use new materials and new technology, to obtain a 96% reflectance. In order to reduce weight lamps, reduce the consumption of metal materials, lighting shell will be a high temperature, high mechanical strength, anti-aging plastic housing direction.
