Q:What is the role of LED downlight
In fact, choose a good day Lantern is a LED lamp energy saving function, ordinary energy-saving lamps should be minimum 5W is generally 11W, a LED lamp bead is 1W, long service life, ordinary energy-saving lamps have radiation, light at 400 nm will produce ultraviolet light is harmful to people, UV will attract insects so the general energy-saving lamp has bugs in the circles above, the LED will not produce ultraviolet
Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?
Is the driver bad or lamp plant bad, general driving problem
Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages
Energy saving: the energy consumption of white light LED is only 1/10 of incandescent lamp and 1/4 of energy-saving lamp
Q:Excuse me, how many different sizes for LED lamp lumens
If we assume power 5W 4 inch downlight case, assuming optical efficiency is 100LM/W, 4 inch downlight ideal luminous flux of 500LM, is on the wreck. The transparent cover is about 400 of the LM, if it is other material non transparent light cover would be lower, probably only more than 300 LM
Q:LED is not only the benefits of downlight what harm?
And before the benefits of lighting equipment is quite obvious, if you really find faults if I feel bad replacement replacement, light bulb was down for a new can, to LED welding, when the current had a high fever bad replacement is more trouble, but because the LED lamp from the battery or the charging the battery power supply, basically there is no current unstable situation
Q:Led downlight can light panel directly with intelligent dimming Mody?
We live by 220 volts of alternating current, and LED by direct current. So all the LED lights will be fitted with a driver to change the current and the voltage. LED lamp dimming according to the change of current or voltage, so Led can directly drive panel light lamp dimming and decided to use intelligent downlight! Ask the supplier can, but generally adjustable lamp will be specified, because the adjustable light is not adjustable to your light!!
Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
5W*3, the key depends on the ceiling elevation.You can use 3 W
Q:How to choose the right LED downlight
Look at the radiator lamps: cooling speed determines the degree of attenuation of the whole lamp and the service life of the radiator is too small will accumulate in the light of internal temperature. Light long time working under the condition of high temperature, light decay very fast, life is short. Our shell and radiator are all thick materials to ensure heat dissipation.
Q:Why use LED lamp light source patch
The patch LED can be fabricated directly on the aluminum substrate and directly cooled to the aluminum substrate to save heat, packaging costs and reduce thermal conductivity losses.
Q:Led downlight and LED flat lamp that is durable
The same, but the shape is different, LED light plate and power module is the same
