Q: The difference between the LED downlight and LED lamp have?: LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. With the continuous development of LED technology, the service life of the LED tube light now generally can reach more than 50000 small. LED lamp is embedded in the ceiling or wall, general lighting products is a kind of highly concentrated, usually it's light to the specified target position. Through light is used to emphasize important points. When working, due to the LED lamp produces high temperature, so the LED lamp when the choose and buy must choose the high quality product, otherwise it will produce safe hidden trouble. Now LED lamp is mainly used for all kinds of commercial space lighting and architectural decoration lighting, etc. At the same time to shoot the light is divided into low pressure and high pressure, proposal consumer had better choose low voltage lamp, due to low pressure lamp life relatively longer, the higher light efficiency. Shoot the light of the general lighting power factor to decide, good lamp power factor can reach 0.99, but the price is much expensive.

Q: 1. I bought the LED tube light, there is some light is driven with constant current, while the input voltage is 220 v, but tend to be low voltage dc output voltage, there are some inserts the 220 v can directly, didn't see any of the constant current drive, so is built into the still say there are two kinds of LED tube light, is a kind of the working voltage of the dc low voltage, a kind of ac 220 v. 2. About the LED tube light, dimmer, I already according to one of the LED constant current drive found the corresponding LED light, that if I was the LED directly to the adjustable light can directly replace the LED constant current drive.: Do you want to light is adjustable brightness or light color? If it is a variable degree of directly replace driver IC is ok, if is the color temperature of the lamp bead can not suitable for you. 3. Your driver output voltage and current, the series multiple lamp after share current, light can't take much more

Q: Led lamp can use ordinary incandescent dimmers adjust brightness.: LED to shoot the light, what do you mean low voltage 12 v or 230 v? If it is 12 v, with light dimmer is not enough, want to be in circuit transformer, otherwise it will burn. Instant connections, estimates that 99% is not enough, because want to let the LED MR16, MR11 shoot the light and the combination of dimmers + transformer matching without flashing, is a technical difficulties, and the head of the LED light source manufacturer will publish a and LED lamp dimmer and transformer matching brands, types and models of CRT, want to match all 100%, in the present on the earth is not human can do, see later, (want Daniel)

Q: How to detect the LED to shoot the light quality is good or bad: When many people in the use of LED to shoot the light, because buy the price so low in the ceiling to appear some problems, a lot of use chip production line lay out to make, do not match color temperature, brightness difference, short service life, the user need to pay attention to.

Q: Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light: For example, A 3 w lamp current is 0.15 A, are two parallel is 0.3 A, then you have to choose the 0.3 A constant current source circuit to the two lamp power supply at the same time.

Q: What clothing store LED lamp, LED lamp can choose?: Shoot the light is placed near the ceiling upper or furniture, also may be placed on a wall, dado or play crural line. The light immediate illuminate is on the items to be highlighted implements, to highlight the subjective aesthetic effect, to highlight atmosphere and unique environment, abundant, rich and colorful artistic effect. Shoot the light is downy, elegant, can play a leading role to the overall lighting, and local lighting, foil atmosphere. 1, save electricity: shoot the light reflectors with powerful function of refraction, around 10 watts of power can produce a strong light. 2, concentrated: concentrated light, can highlight or emphasize a particular object or space, adornment effect is obvious. 3, comfortable: color close to natural light that shoots the light, the light reflection to metope, not dazzling.

Q: The ceiling of a ceiling light is of general size: And the size of the wattage for the 70 w lamp also has two kinds, one is opening, width is 205 * 110, height is 205 a; The other is 180 * 137 opening, width, height of 220. Then there is the lamp wattage for Max300W, the size of openings and width 150 * 287, 391. Then there is the lamp wattage for Max300W, the size of openings and width 150 * 287, 391. And Max120W shoots the size of openings, 130 * 220, wide and high is 309. The size of the lamp for 35 w generally has two kinds: the first is a opening, width is 205 * 90, the size of the high of 170. Usually shoot the lamp to the size of holes to 45 mm, 50 mm, 55 mm, 60 mm, 65 mm and 70 mm, 75 mm and 80 mm, 90 mm and 100 mm.

Q: How can you make the led lamp not dazzling: Initially LED is used as the indicator light instrument and then all kinds of light color of LED traffic light and display screen has been widely applied in large area, produced good economic and social benefits. 12 inches of red traffic lights, for example, in the United States could have been used long life, low luminous efficiency of the 140 - watt incandescent lamp as light source, it produces 2000 lumens of white light. After the red filter, light loss 90%, only 200 lumens of red light. And in the light of the new design, Lumileds companies adopted 18 red LED light source, including circuit loss, total power consumption of 14 watts, can produce the same light. Car light is also an important field of LED light source.

Q: Does the background wall light 3 watt led enough: LED light source on the luminous principle, energy-saving, environmental protection level are much better than traditional lighting lamps and lanterns. And LED the unidirectional formed to shoot the light distribution of the perfect support.

Q: LED lamp biggest can do how many watts?: Shoot the light is a broad concept, source of coherent light can be classified as to shoot the light, shoot the light, such as smallpox large wattage lamp can be classified into the light. In the industry generally called PAR20 size small lamp holder to shoot the light, this kind of lamp in accordance with the lamp bead quantity biggest can make 5 * 1 w, 3 * 3 w. Above PAR30 habit called PAR lamp, size is larger, 18 w can do it. Other large wattage of the gymnasium, outdoor project-light lamp, stage lamp wattage do 200 w is very normal. The hope can help you
