Q:Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light
You want to work until 3 w leds first what is the current, now that is a parallel, the output current is the sum of two current in constant current source circuit.
Q:How to distinguish the LED lamp wattage?
Open shell, look at the LED module inside the chip count, are generally use 45 mil, single chip is 1 w, 30 w, 30 is 50 is 50 w, 100 is 100 w, the chip number add up to the wattage.
Q:How much is the LED to shoot the light, color rendering index in general
> 80, we have integrated LED lamp, luminous efficiency is very good, now try shimao riverside Hilton Hotel in nanjing, you can search: the star of the EPC contract energy management, learn more shoots the knowledge well
Q:How much time LED lamp life
LED the whole lamp life means establishing droop 30% of the time, the higher the temperature of the solder, the more serious the droop, at the same time because of the LED drive power components in the limited life (especially the electrolytic capacitors under high temperature electrolyte dry), so we all find balance in cooling costs and the temperature of lamps and lanterns
Q:What is the difference between LED lamp and LED lamp cup?
Above to distinguish from the product performance: 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:The difference between the LED lamp
Applied position Tube light is usually thought to be installed in the ceiling, condole commonly need over 150 mm to pack. Of the canister light, of course, there are external type. In the absence of dome light or droplight installation tube light is a good choice, relative to shoot the light wants downy light. Shoot the lamp to be generally can be divided into orbit type, hanging and embedded, etc. Shoot the light with transformer, but also have without transformer. Embedded within the lamp can be installed in the ceiling. Lamp is mainly used in the need to emphasize or performance. Such as TV wall, hang a picture, accessories, etc., can play the light to enhance effect.
Q:What is the input voltage of the mr16 led?
The input voltage of dc DC12V, 24 v. LED lamp is to use leds as a light source to shoot the light. Traditional lamp used more halogen lamp, luminous efficiency is lower, more power consumption and environment temperature rise by illuminate, service life is short
Q:Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?
Ok, now are LED lamp to replace the original quartz bulb,Can be used, but there must have a circuit inductance/curtains on tube/semiconductor current limiting device (using single-chip microcomputer control)!!!!!
Q:Aquatic plants cylinder light can use LED lamp?
Current leds are not suitable for plants, plants or a professional grass lamp is best, followed by the philips 865 color temperature (6500 k) and 6500 (color temperature 4000 k) series of tubes.
Q:Led lamp light source plate can change yourself?
If sure just light bulb is broken, if change is not very troublesome, then change the light bulb, because the lamp you use isn't a long time, you can buy a light bulb, because they are for my own household, expensive with the cheapest price
