4 Quality Tests of LED Wall Washer

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 immediately after aging test.

Waterproof Test

Waterproof test should be done right after the aging test so as to simulate a real environment for IP protection test of LED wall washer. This approach is generally known as thermal test. After lighting for a certain time, LED wall washer would be heated up to a temperature. The waterproof test carried out under this condition would help to ensure whether LED wall washer would work well in a bad outdoor environment.

Failure Test

Failure test is essential to quality certification test. This test would simulate failures that may occur in practice in order to assess the safety when products fail. Thus, many manufactures would add proper fuse to the input end of LED wall washer to prevent a fire risk caused by an output short-circuit or component failure.

Why LED Strip Light Won't Light Up? Troubleshooting

Today we'll answer the frequently asked question. " why LED strip light won't light up ". If you find your flexible LED strip light won't light up or power up, you may check the following troubleshooting information for help. 1. The lamp beads of led strip light must be broken or damaged during transportation if the light is not covered with full protection. 2. There must be a faulty at the light's soldering points. The soldering may come off if there is any shock during transportation. 3. Soldering with poor quality may cause embrittlement or shedding when the strip light is bent for use. 4. Cheat on tin soldering materials can also cause the same problem as the 2 point we just mentioned. 5. LED lights with flexible installation bending angle is too large, resulting in LED lights with flexible joints and lead to bright copper separation 6. A excessive bending may result in the disconnection between the joints and copper foil. 7. Thick sol

Difference Between Downlights and Spotlights

Many people are confused with downlights and spotlights. They could not tell the difference between the two types of lights, let alone the lights' application and lighting effect. Downlight VS Spotlight Simply speaking, downlights, used for general or auxiliary lighting, have more concentrated lighting source than ordinary ones. Spotlights can emit a highly-converged spot light. It is used for special illumination, such as highlight a place or object with bright spot light. We'll distinguish the two types of lights from the following aspects. 1. Lighting. Downlights can be installed with incandescent bulbs or energy-saving lamps. If you use incandescent bulb, the light would be yellow; while if you use energy-saving light bulb, the light would be white or yellow. The lighting direction f ceiling downlights could not be adjusted. But the direction of the spotlights can be adjusted freely. A quartz bulb or lamp beads are usually used for household spotlights.

How to DIY LED Home Light?

Although LED lights have many advantages in many applications, it's still a little expensive for home use. Today, I'll going to tell you how to DIY LED home light . This DIY idea comes from a college student. I'll show you how he did it by himself. "I have many lamps installed on the ceiling at home. All of them are energy-saving fluorescent lamps. The problem is I have to buy new bulbs to replace them many times every year. I think it over and find that the investment on lighting is almost equal to the daily energy-saving. Besides, the discarded bulbs is a big pollution to the environment. So, I wanted to DIY a long-life LED lamps for home, which is energy-saving and money-saving." LED lighting for Residential Use How to DIY LED Home Light? "I have a rechargeable flashlight with bright light-emitting diode(LED) light source. It's been in use for more than two years. Although it dropped down to the ground for several times and the shell is

Difference between LED flood light and LED spotlight

Both LED flood light and LED spotlight are widely use for illumination and decoration purpose. Some people can not tell one from the other clearly. Today I'm going to show you the difference between led flood light and led spotlight. LED Spotlight and Applications LED spot light, also led spotlight, is mainly used for architectural lighting, as well as commercial lighting purpose. It plays a big role in lighting decoration. There're different shapes of spot lights, round, square, etc.. Due to the thermal factor in design, the shape of LED spotlight differs from that of traditional one. Home LED Recessed Spotlight LED spotlights are mainly used for decoration, commercial lighting, and architectural lighting. They're excellent in lighting decoration. The lights can achieve many lighting effects, like gradual changing, transition, color flashing, random flashing, alternating gradient and chasing, etc..

Price Trend Forecast 2014~2040 for LED Light, Fluorescent Light, N' Incandescent Light

Efficacy & Price Trend Forecast 2014~2040 for LED Light, Fluorescent Light, N' Incandescent Light Lighting Efficacy Cost U.S.Energy Information Administration predicts that the price of LED light is almost close to that of fluorescent light or incandescent light by 2020. At that time, incandescent lights are probably eliminated as they could not meet the energy-saving standards in next few years. On January 1, 2014, the United States banned the production and sales of 40 watt and 60 watt incandescent bulbs; but many American families store a number of these traditional bulbs before the ban. Probably, 75 watt and 100 watt traditional light bulbs would also become one part of the ban. Due to the the federal standards and development on lighting technology, the bulbs' quality sees a great improvement; the service life and lighting efficiency also increase a lot acc

Difference Between Flexible LED Strip and LED Light Bar

As we mentioned in " What's LED strip ", LED strip can be generally classified into two main types, flexible LED strips and LED light bar. Today, we're going to tell the difference between flexible LED strip and LED light bar . Flexible LED strip is made of FPC circuit board assembled with SMD LED. The thickness of the strip light is only that of a coin, which make it save more space. The most common specifications include, 30cm with 18 LEDs or 24 pcs of LEDs, and 50cm with 15 LEDs, or 24 LEDs, or 30 LEDs and so on. Of course there are also strips in 60cm, or 80cm. Stip lights of different specifications are used for many different applications. People can cut or prolong flex LED strip for its own use; however, the luminescence would not be affected. The LED strips with FPC(soft material), can be bent, folded , winded, or stretched in three-dimensional space without breaking. Flexible led strip is suitable for irregular use or cramped places. It's also

Flood lights with good antistatic have longer service life; therefore they enjoy a higher price. Usually, the antistatic factor of LED should be over 700V. 3. LEDs with the same wavelength and color cost more money. It is difficult for manufacturers to produce LED floodlights with pure colors if they have no spectral separation devices. 4. LED flood light is one-way conductive light. If there is a reverse current, the situation would be called leakage. Leakage current leads to short service life and low price. 5. The LED cost defers from one another due to different illumination angles. LED flood lights wi
