World Leading Heat Dissipation Technology---Only one piece of “BLACK SLICE” could replace the primitive heat dissipation-Thermally Conductive Silicone and greatly increase LED Downight Lifespan.
Introduction
*A special Zero-heat capacity in composited material using Nanotechnology.
*The heat of P-N Junction is diffusing at a speed of microsecond unceasing, thus lowers the
junction temperature drastically.
*The heat from the light source escapes to the radiator in the way of heat exchange between
positive and negative electron in wave patterns.
*Non-Volatile and long lifespan.
The shortcoming of Thermally Conductive Silicone:
*Volatile, result in a thermal resistance
*Easy to aging
*Difficult to plastering
*Low thermal conductive coefficient (1-3w/m.k) compare to our “BLACK SLICE” thermal diffusivity (200-300w/m.k, 260m^2/s).
- Q:How are LED lamp quality is good or bad?
- Light source. Professional manufacturer of LED downlight tells you that the power quality LED lamp generally adopts imported Samsung point light source. Light source is chosen well, its lamp quality is bad also not where to go.
- Q:LED lamp power off why would light up
- The distribution of capacitor connected switch contacts of parallel line formation (originally existed), after turning off the switch can still trace by alternating currentYou used a small light source lamp power LED lamp (mA current to shimmer)The combined effect of the above.
- 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:LED lamp is mainly used in where
- 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 lamps, which do not use the feeling of oppression, on the contrary will produce a warm effect. Therefore, the home can choose to install multiple lamps downlight, reduce the space sense of oppression. Usually in hotels, families, cafes, shopping malls LED downlight more. Indoor lighting LED lamp has strong applicability, but also because of its many other advantages. 1, the use of LED lamp for home improvement is more beautiful. Downlight help overall unified and perfect to keep indoor decoration, do not destroy the chandelier lamp light source set, hidden in the interior decoration, not exposed, no glare, visual effects LED light giving more soft and uniform. Energy saving 2, LED to help families reduce electricity costs: the same brightness power for the ordinary energy-saving lamp 1/4, a LED lamp can save electricity tens of dollars a month for a family. 3, LED lamp is not fragile, Recyclable, strong environmental protection: do not contain mercury and other harmful substances, no pollution to the environment. And its power saving is equivalent to reducing carbon emissions. In line with the family "energy-saving emission reduction" concept of life promotion. Longevity: LED 4, LED downlight lamp life of 50 thousand hours, six hours a day, is a life span of 20 years. This reduces the cost of buying lamps for families.
- Q:LED ceiling lamp and LED downlight what is the difference
- Is owed to the concealed downlight, diffuse light, mainly regulate the indoor light effect, and spotlights are surface mounted, direct light, mainly to highlight the background picture or object, two lights are installed at the top of the.
- 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:Now there is no replacement of the LED light source lamp?
- Yes, the finished product is one, 25 yuan a, excluding postage, 3W
- Q:What brand of downlight is good? Please explain the reason, thank you!
- Cost. From a cost perspective, the LED lamp price is about 3-10 times of the traditional lighting range, if the power of the time more than 6 hours a day, LED lighting is good, is expected about 1 years to be able to save money to buy a lamp; if one day 2-3 hours, it is not how much electricity the.
- Q:LED downlight, embedded lamps, lamp tube and difference?
- I. definitions1, downlightThe lamp is generally a lamp holder, lamp can be directly mounted incandescent or energy-saving lamps. Is a lamp embedded into the lighting ceiling light shooting style. Its biggest characteristic is to maintain the overall unity and perfection of the building decoration, not because of the setting of lamps and lanterns, and destroy the perfect unity of ceiling art. The recessed luminaire, mounted inside the ceiling, projects all the light downward, directly to the light. Different light effects can be obtained with different reflectors, lenses, louvers, and light bulbs. Table space, can increase the space of the soft atmosphere, if you want to create a warm feeling, can try a lamp lamp, reducing the spatial sense of oppression. Generally in the hotel, family, coffee shop use more.
- Q:Led downlight and LED flat lamp that is durable
- The same power cases are led lights, the length of life depends on his cooling conditions, the better the heat dissipation, and its life is relatively longer
