Q:The ceiling of a ceiling light is of general size

The first is the difference between the different wattage specifications: on the one hand 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; The second is opening, width is 243 * 106, the specifications of the high of 198. And 20 w lamp is generally only one, that is opening, width is 235 multiplied by 106, the specifications of the high of 198. A third type of even 50 w to shoot the light, the size of the gas is opening, width 235 * 106 plus 198.

Q:Sitting room condole top round with tube lamp or LED lamp good?

Tube lamp brightness is general, if the home of two Suggestions to shoot the light, the effect is better you know [like]

Q:LED lamp PAR30 - more than 40 w hours kilowatt-hour

40 tile does not generally foot tile, about 25 hours to 30 hours once electricity. Actually I am not recommend you use the lamps and lanterns of LED PAR30.

Q:Home use shoot the lamp to general how many watts is the best?

Shoot the light is a typical advocate the lamp, wuding scale modern genre of lighting, can create an atmosphere of indoor lighting, if a row of small shoot the light, the light can change the wonderful designs.

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.

Q:Cob lamp and led lamp that electricity consumption big?

Cod to shoot the light electricity consumption. Cob lamp is to use the cob LED light source as a light source to shoot the light. Traditional lamp light source used more halogen lamp and high power led, halogen lamp luminous efficiency is lower, more power consumption and environment temperature rise by illuminate, service life is short; And local too light efficiency, high power led light spot uneven, with the dark. In LED luminous principle, energy-saving, environmental protection level are much better than traditional lighting products. And LED the unidirectional formed to shoot the light distribution of the perfect support.

Q:Shoot the light track shoot the light

Track shoot the light guide light, belongs to the accent lighting lamps and lanterns of a commercial lighting product type. Orbital lamp lights are suitable for all kinds of needed rendering, focused on the interior space environment lighting, widely used in museums, libraries, commercial shops, hotels, clubs, catering, professional venues, such as indoor Spaces, the current domestic track shoot the lamp to be more good brand with philips, thorne, leishi, WAC lighting, panasonic, mount tai, sidon, op, mitsuo aurora, kei, lighting, TCL lighting, the lighting, etc. Track the fixed installation commonly used guide to shoot the light. Track the conventional two lines, three lines, four line connection ways, can free combination, length is 1 m, 1.5 m, 2 m, etc., the orbit can suck the top fixed installation, lifting, etc. Now most of the guide rail lamp USES the longer life, more energy efficient LED light source, the traditional halogen lamp and metal halide light source is slowly.

Q:The original old how long pole to shoot the light to LED lights

Transform the power The lamp is with electronic transformer is 220 V / 50 hz ac DianZhuan into 12 V high frequency alternating current (ac) for the use of shoot the light, for the LED power supply. Now should be high frequency ac DianZhuan into 12 V dc 12 V, so that power can be multiple groups of three series of LED lights (in terms of each only 3.5 V), each lamp visible need more groups in parallel, in order to reach a certain brightness. To add a high-frequency electronic transformer rectifier filter circuit, it can be high frequency ac DianZhuan into 12 v dc 12 v. Rectifier with high-frequency rectifier tube, HFC L can use energy-saving lamps of the circular on the glass with plastic envelope around 10 turns the substitution. Cut a small piece of PCB on the above components on the electronic transformer, after connected with insulated wires - and into electronic transformer molded case, output leads to +, - two power supply line.

Q:Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light

Upstairs to answer the wiring method in theory can be bright, but if one of the lamp is broken, because it is a constant current driver, another lamp will inherit the double current, quickly burn out. So the correct connection is the use of double current unchanged, power driver, serial connection.

Q:Best lighting distance of LED to shoot the light

LED lamp its rays distance depends on the light Angle. The power relationship between size is not very big.
