Q:One of the ten famous brands in LED lamp have? How to differentiate between light and guide lights

Guide to shoot the light leishi and sidon, WAC lighting, mitsuo aurora, tai teng lighting, lighting on the SAT, kei, lighting, lighting products, TCL lighting can also be done.

Q:Led to shoot the light color temperature 3000 k what do you mean who knows

Color temperature is the most common said light source spectrum quality indicators. Generally expressed in Tc. Color temperature is defined in absolute blackbody, absolutely blackbody radiation and light radiation in the visible area all at the same time, the temperature of blackbody is called the color temperature of light source. Low color TPS source is characterized by energy distribution, relatively more red radiation, commonly referred to as "warm light"; Color temperature increase, energy distribution, the proportion of blue radiation increases, often referred to as "cold light". Some commonly used color temperature of light source are as follows: standard candle is 1930 k (kelvin temperature unit); Tungsten is 2760-2900 k; Fluorescent lamp is 6400 k; Flash is 3800 k; At noon the sun is 5000 k; Electronic flash light for 6000 k; The blue sky is 10000 k.

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:Stationary LED to shoot the light is not bright, how repair

Unload the good and bad two shoot the light, at the same time access to exchange position, you can determine fault or line is to shoot the light

Q:What is the main purpose of LED to shoot the light? What is the difference between it and the ball lights, mainly performance and USES.

In addition, in order to facilitate maintenance, LED projector lamp adopts open behind replacement bulbs. Excellent decorative lighting effects, LED project-light lamp can realize the gradient, jump, color flashing, random, alternating gradient and chase, scan and other dynamic effect

Q:Ask high people to instruct the LED light maintenance method

First look at what is the power of your light tile; Then the lights down, the power supply removed; In a similar power drive; This problem is more common; Is the driver burned; If you don't know what reason Can I direct messages;

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:Why turn off the switch and dim the led lamp

A common cause of ED lights flashing and the solution: After turn off the power supply LED lights flashing, check the switch control is zero. If the correct wiring may refer to the following methods: The human eye can generally perceived frequency of 70 Hz light flashing, higher than the frequency does not perceive. So in LED lighting applications, if the pulse signal frequency is lower than 70 Hz low frequency component, the human eye will feel the shine. In the specific application, of course, there are many factors may lead to LED lights flashing. For example, in an off-line low power LED lighting applications, a common power supply topology structure type is to isolate the flyback topology. In accordance with the "energy star" solid-state lighting standards from line 8 w LED drive GreenPoint ? reference design as an example, as a result of the flyback voltage stabilizer sine square wave power conversion did not provide primary offset constant energy, dynamic self-supply (DSS) circuit may activate and trigger light flashing. To avoid this problem, must enable primary bias to partial discharge in each half cycle, accordingly, need to choose appropriate constitute the bias circuit of capacitance and resistance value.

Q:Led to shoot the light, how much is seven bubble of v

If the lamp bead (except the red light) is connected in series is about 21 v. A single light red beads of voltage is 2.1 V - 2.3 or so. In addition to the red light of the other is 3-3.5 V.

Q:The PAR value of lamps and lanterns is what mean?

PAR photosynthetic active radiation abbreviations: photosynthetically active radiationPAR photosynthetic available radiation, green plants for photosynthesis process, absorption of solar radiation in the chlorophyll in excited state that part of the energy spectrum. About 400 ~ 700 nm wavelength, represented by symbols Qp, units of w/m 2. Photosynthetic active radiation is plant life activities, organic material synthesis and yield formation of energy sources.
