LED Lighting

LED display is popular for indoor and outdoor display applications. To get the most out of your LED display, I put together this simple list of do's and don'ts for using. It's simple yet quite informative. 1. Do start PC before switching on display screen; and shut the PC off after switching off the display. If you do it in a wrong way, it will cause a serious failure in display and LEDs. 2. Make sure that the interval between switching on and off the display is over 5 minutes. 3. Better to power up the LED display after you access the project control software in computer. 4. Do not start up LED display when it's all white in screen, because the current impact to the system reaches the maximum. 5. Do not start up LED display if the controlling section is not power on. 6. Do not use the display for a long time if the ambient temperature is too high or against heat dissipation. 7. Do shut off the display screen if one part of it appears very bright....

If you're going to buy LED displays, you'd better check the following information for reference. 1. Flatness. LED display's surface flatness should be within ±1mm so as that the displayed image is not distorted. A partially-raised section or other types of unflatness would cause a viewing angle problem. Flatness is mainly determined by the quality of production process. 2. Brightness and View Angle. Proper brightness is a key factor to LED displays' performance. The brightness of indoor full-color LED display is about 800~2000cd/m2, and outdoor full-color displays' brightness is 5000~7500cd/m2. A higher or lower brightness over an actual need would lead to invisibility. Screen brightness is determined by the size of LED chips. View angle directly affects how many audience the display is good for; thus, in a certain circumstance, the larger the view angle, the better the LED display. Outdoor full-color LED Display 3. White Balance Effect. Whit...

Before you carry out a big purchase for LED display screen, you'd better check the following information first. 1. Brightness. Generally, brightness varies in accordance with different applications. A. Brightness for indoor use> 800CD/M2 B. Brightness for semi-indoor:> 2000CD/M2 C. Brightness for outdoor use(display screen faces north):> 4000CD/M2 D. Brightness for outdoor use(display screen faces south):> 8000CD/M2 The brightness of red, green and blue light contribute differently in composition of white light. Here a are some data and specifications for you reference. Generally brightness ratio for these 3 colors is 3:6:1. Precise ratio is 3.0:5.9:1.1. With a certain brightness and pixel density, the calculation for a single-tube's brightness would be as follows. Take two red light, one green, and one blue light for example. Red LED light's would be: Brightness (CD) / M2 ÷ Pixels / M2 × 0.3 ÷ 2 Green LED light's brightness: brightness(...

Features of LED Display Compared with other large-screen terminal displays, LED display has the following characteristics. 1. High brightness. The brightness of outdoor LED display is over 8000mcd/m2. This kind of display is the only large-scale all-weather display that could be used for all day long. The brightness of indoor LED display is over 2000md/m2. 2. Long service life. LED's service life is up to 100,000 hours (about ten years) or more. This specification refers to the design life of LED. 3. Large view angle. Indoor LED display's view angle could reach 160 degrees or more; and outdoor LED display's view angle is over 120 degrees. The view angle is determined by the shape of light-emitting diode. 4. LED displays vary from each other in size. There is 1 square meter display as well as displays of hundreds or thousands of square meters. 5. It's easy to connect LED display with computer. The display supports numbers of software. Installation ...

There're many types of LED display for choice. Generally, LED displays could be classified in following ways. 1. Classification by Application. LED display could be used for indoor, outdoor or semi-outdoor applications. Indoor LED display generally ranges from less than 1 square meter to over 10 square meters. It's usually used for indoor applications. This type of LED display has a moderate brightness, large viewing angle, but light weight. It's suitable for watching at a close range. Outdoor LED display's area is from several square meters to 10 or even hundreds of square meters. Its brightness is around 5500~8500cd/sqm. This display sreen can be used under the direct sunlight. It's better for watching from a certain distance, say tens of meters. Besides, this outdoor LED display is weather-proof and lightning-resistant. LED Display (Times Square, NY) Semi-outdoor LED display screen has a relatively higher brightness than indoor LED display. I...

Do you know how many and what tests should LED wall washer undergo for quality certification before delivery? This article would help you to know it. Temperature Test Temperature test is a must in quality inspections of LED wall washer. There's a temperature limit for different components. During product designing, manufacturers should pay great attention to heat dissipation, especially that of certain components, such as insulation sheet. Components could be easily damaged if working under a high temperature condition for a long time. This might cause a fire or electric shock. The internal power module of wall washer is enclosed in a small space, which might lead to a heat problem. Therefore, manufacturers should select components in proper size, which would avoid the over-heating problem when the components work under full-load condition. Aging Test  LED wall washer should undergo a 24-hour aging test before delivery; and waterproof test should be carried out im...

Here I'm going to show you 7 basic specifications of LED wall washer that you'd like to know before buying. 1. Power Power is a key factor determining LED wall washer's projection distance. Generally, the power could be 18W, 24W, 36W, 48W, etc. However, the power is flexible. It could be changed upon different requests. Usually, high-power LED wall washer is always in a single row. Concerning on heat dissipation, the power of 1-meter-long wall washer, which is designed with couples of 1W lighting bulb, must not exceed 36W; otherwise, a serious Lumens depreciation would happen as a result of heat dissipation problem. 2. Voltage DC power or AC power. Usually, build-in power supply requires AC 220V(AC110 in Japan), but external power supply requires low voltage, like DC24V, DC12V, DC27V and so on. The voltage could be different due to different customers' requirements. 3. IP IP protection is also a basic specification of LED wall washer. What's IP pro...

As mentioned in " 4 Aspects to Understand LED Stage Light ", LED wall washer is a very important part of stage lighting. Well, it's not only used for stage lighting, but also a nice choice for indoor and outdoor lighting. Now I'll show you what's LED wall washer . LED wall washer is mainly used for architectural lighting purposes. As described by its name, the light comes from LED wall washer is like water washing all over a wall. It's energy-saving, and high luminous efficient. Now traditional wall washer light is gradually being replaced by LED wall washer. The power module for LED wall washer is installed inside the housing, of which the space is very limited. Therefore, some manufacturers, in order to save space, weld the pin-type components onto PCB board, which could cause a big problem in quality. These surface-mounted components could easily come off because of bad soldering. That's very dangerous. LED wall washer, controlled by a bui...
