Q:How are LED lamp quality is good or bad?

3, light. Good LED lamp 25000 hours before the light is less than 30%, the main factors are the light source and the light however decided the quality of radiator. And better light sources have foreign CREE and so on.4, light effect. Luminous efficiency is the lumen number per watt, in units of LM/W. It is the reaction power saving performance of LED downlight. The better the power saving performance, the higher the light efficiency will be.

Q:LED lamp power off why would light up

To understand electricity, CBB downlight electric capacitor in the AC input terminal 2 connection between bridge above, 1 pressure capacity of 400V 0.22 micro method and above, good quality point, usually you can solve your problem.

Q:Excuse me, how many different sizes for LED lamp lumens

If you want to output LM, we must first choose high light efficiency of the lamp, this problem because there is no explanation for what your power and lamp type lamp, so I can not estimate

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: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: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:LED is not only the benefits of downlight what harm?

Also not, and now the quality of LED products vary greatly, I have a lot of new customers say where to buy Lamps and lanterns used to be broken, although the price is cheap, but the quality is not pass

Q:How many good color family LED downlight

The living room should be according to the style of the decoration. The Yellow warm colors with brilliant style, bright and clean with white, as long as the color temperature is more blue, like moonlight, lower yellow, like the sun sooner or later (incandescent light) color, like the 4500-5000k noon sun

Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide

The average height is around 45mm-60mm. If your space height is greater than 60mm, you don't have to worry.

Q:The general living room to Amdo large size of the lamp?

Now more and more office and family on the use of LED lighting lamp. Because of the more and the applicability of the LED lamp used in indoor lighting more people know, is becoming more and more popular. LED has some other lamps downlight incomparable even other LED lamps can not compare the applicability of indoor lighting LED lamp does not occupy the indoor space in the indoor installation of LED downlight, because hidden lamp, do not use the pressure. Forced feeling, on the contrary will produce a warm effect. Therefore, you can choose to install multiple lamp decoration lamp, reduce the pressure of space. A sense of urgency.
