Q: Home decoration, want to buy lights, with what kind of lamp well?: The local lighting of the restaurant should be equipped with hanging lamps for convenience of dining.4. bedroom selection of light, elegant and comfortable. Several lights can be used in mixed, soft, decorative lamps can better contrast the bedroom warm and elegant atmosphere.5., study light, auxiliary light source, the most important study lighting should be bright, soft as the principle, the desk lamp should choose with reflective cover, the lower part of the open direct desk lamp, light source, often fluorescent lamp.

Q: Why does the LED light change color?: 50 years ago, people had already understood the basic knowledge that semiconductor materials can produce light. The first commercial diode was produced in 1960. LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is an electroluminescentsemiconductor materials, placed on a wire rack, then sealed with epoxy resin around, to protect the internal core function, so the seismic energy LED.The core part of the LED is a wafer consisting of type P semiconductors and type N semiconductors. There is a transition layer between the P type semiconductor and the N type semiconductor, called the p-n junction. In some PN junctions of semiconductor materials, the injected minority carriers combine with the majority carriers to release excess energy in the form of light, thereby converting the electric energy directly into light energy. PN junction plus reverse voltage, the minority carrier is difficult to inject, so it does not emit light. The diode, produced by injection electroluminescent principle, is called light-emitting diode, commonly known as LED. When it in a positive state of the work (which ends with forward voltage), the current flows from the LED anode cathode, semiconductor crystals on the issue from the ultraviolet to infrared light of different colors light and the strength of the current.

Q: Waterproof LED lamp belt used after a period of time, there is a part of the lamp with white into orange, what's the matter?: General waterproof lights are used in epoxy waterproof, this glue easily oxidized low cost, most manufacturers are using this.There is also a silicone waterproof, this performance better, but the higher cost. Next time you buy, you can weigh and choose!The above answer, I hope to help you.

Q: How long can the LED lights be connected with a transformer?: Low pressure, suggest a single not more than 15 meters. Never exceed 20M for the longest and longest. How large is the output power of a switching power supply? You have to be sure. In actual installation, the power amplifier can be connected

Q: How does the LED light band connect the dimmer controller?: Provide dimmable dimming and communication interface for LED dimmable constant current drive power, dimmable electronic ballast.

Q: What are the uses of an LED lamp?: LED light belts are now widely used in buildings, bridges, roads, gardens, courtyards, floors, ceilings, furniture, cars, ponds, underwater, advertising, signs, signs, etc..

Q: How do you fix the LED band when you step on the stone?: With a transparent plastic or glass glue directly to the LED lamp with paste on the marble surface, this method in order not to affect the LED lamp with visual effect, the construction need to be especially careful carefully, but generally only suitable for temporary applications

Q: What brand is the LED lamp with?: If you want to buy, first of all, pay attention to test the anti-static ability of LED lamps. Antistatic capability is one of the important criteria to judge the quality of LED lamps. Generally speaking, LED lamps with high antistatic capability have long life and have higher safety factor. Therefore, in the purchase of LED lamps, be sure to pay attention to the strength of its anti-static capacity. Secondly, pay attention to check whether the current leakage exists in the LED lamp. And general lamps are different, LED lamps belong to one-way conductive light, if there is reverse current, this is the leakage. Once the leakage current of the LED lamp is large, the service life of the LED lamp will be relatively short.

Q: How do I choose the light belt?: LED lights with the second line, three lines, four lines, five lines mean?LED lamp belt according to the lamp belt, the internal cable is divided into round, second line, flat three lines, flat four lines, flat five lines four kinds.LED lamp a: tier with internal cable two, one line series lamp, and another is the wire. So there are two lines, line zero points, that is to say in the plug when the two needle is not bright, only the two pin plug inserted can turn 180 degrees again.LED lamp b: flat three lines with three line, two line series lamp, the two wires located on both sides. One of the middle is the power line. So the correct insertion is only to insert the pin into the wire. Unlike the second line and the four line, the plug has pros and cons.LED lamp c: flat four lines with four line, three line series lamp, one of which is in the middle of the wire. Therefore, the center of these two lines have zero, FireWire, that is, in the plug may be not bright, the solution is only four pin plug to 180 degrees, and then plug it.LED lamp d: flat five lines with five line, four line series lamp, the four wires located on both sides. One of the middle is the power line. So the correct insertion is only to insert the pin into the wire. Unlike the second line and the four line, the plug has pros and cons.

Q: How to fit the proper driving power for the LED light?: General LED lamp series, LED current generally at around 20 mA, the total power consumption of each P light = 220X0.02=4.4 watts. Power is electricity 220V.
