Q:Led bulb light beam width led ball steep light Angle is usually?
Different types of lamp bead is not the same, like LED lamp bead is 38 degrees to 45 degrees, SMD lamp beads is generally 120 degrees
Q:LED to shoot the light always blink what's the problem?
Yes, you open it to see inside is very simple, a power a lamp panel.
Q:30 square meters, 3.1 meters high clothing store lighting need how many watts of led lights
Energy-saving lamps Since the lighting effects Until their satisfaction Light can change back Won't you tell me the website to buy it As long as the heart is not as difficult as can be
Q:Why turn off the switch and dim the led lamp
Mainly because of internal power filtering capacitance. When the power is shut down, capacitance on the surplus electricity will let LED continue to dim light for a while. Capacitance discharge, it is for this reason...
Q:The difference between the LED downlight and LED lamp
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. On the second place in application to distinguish: LED tube lights are mostly installed in the ceiling, above ceiling to 150 mm is required to install. Of course, there are LED tube light is of the external type. General selection in the absence of the location of the dome light or droplight to install the LED tube light, the light is slightly softer than shoot the light. The LED lamp can be divided into several categories: type, hanging and embedded, etc. To shoot the light is divided into with transformer and without transformer. That belongs to the embedded in the ceiling.
Q:How to distinguish the LED lamp wattage, such as the 12 piece is how many watts
On the market, shoot the light bead to 1 w/lamp bead more. The intensity of illumination, according to the requirement of the individual to buy.
Q:The LED lamp which cheap compared with bovine eye lamp
Advantage of led long service life.Some people say that led to more expensive than bull 's-eye.
Q:How many W LED lamp can and ordinary 35 W lamp as light
Light they are made with premium brands, CREE XPE, EDISON power they adopt Taiwan new. 3 watts of power price in $12 to 15 yuan. The shell is air cooling aluminum. But their canister light only suitable for commercial lighting. To general lamps and lanterns manufacturer expensive, because of the different materials used. We do engineering have been use their lamps and lanterns. They shoot the lamp to do pretty good also. West rail into light source are in Japan If is halogen lamp, 5 watts. 5 = 35 watts
Q:The difference between tube lights and shoot the light
features 1, compact and high luminous flux. Incandescent light bulbs, energy-saving lamp power consumption is 1/5, life is 6 times of incandescent lamp, held the 175 compact design size, inhibits the presence of lamps and lanterns, create bright space. 2, a mirror and frosted two reflex plate. Bring light flashes of specular reflection board, moderate degree of CDH to reconcile the grinding sand mold reflection of the ceiling board. 3, the sliding clamp, construction is convenient. Can be installed in 3 mm to 25 mm of different thickness of the ceiling, maintenance is very convenient when lamps and lanterns will be removed. 4, energy-saving lamps, there are plenty of color temperature, the commonly used 6400 k (white light), and 4000 k (neutral light), and 4000 k (yellow), three types of the three kinds of color temperature can create a different atmosphere. According to the different USES to select the most appropriate color lamp.
Q:Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?
The power of the LED lamp is using a constant current power supply, and shoot the lamp to use 12 v constant voltage power supply, the nature of the power supply is not the same, if used on the LED constant voltage power supply, will directly cause damage to the LED current is too large. Therefore, shoot the light output 12 v transformer 20 to 50 w can't be used for LED lamp.
