Q:Why the LED lamp (white light) edge hair blue light shone on the wall
Therefore describe white LED color generally mild corresponding color area of x and y coordinates on chromaticity diagram, rather than general said the white light, a lot of people to describe you need white color temperature, actually also is not accurate, color temperature on the chromaticity diagram is a linear value, a color temperature value corresponds to a variety of colors.
Q:Stationary LED to shoot the light is not bright, how repair
Bad swap places after good, is the question about which line, otherwise is the problem that shoots the light
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 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:The difference between led grille lamp and dared light
Dared light is usually a commonly known as the grille lamp, because the appearance of lamps and lanterns of the tank using light source similar to "fight" (old instruments of food), so also called dared lamp, also have called "the bean pot lamp", should be the harmonics. Dared light panel is made of high quality aluminum alloy profile, after spraying processing, flashing silver, rust and corrosion resistance
Q:The same power of cob and led lamp which is brighter
Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.
Q:With current meter how to detect the led lamp lights, bad
Can find a lithium battery (or 3 section dry cell in series), series a hundreds of the resistance, to the led lamp bead, try on the reverse, if the light is good, light is not bad
Q:On the ceiling lamp bulb is broken can change LED light bulb?
First to see on the ceiling lamp is one of the, or separately. If it is a separate bulb can change LED light bulb or lamp; If a body would need to whole in together, can't change the light bulb. The traditional lamp light source power, high heat, and electricity. LED lamp power small high brightness, low heat also save electricity, more secure.
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:Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?
Transformer are interchangeable, but LED is a dc power supply, if the pressure after the bridge rectifier, more than 12 v, also need to consider the LED string and method and current limiting resistor.
