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?
1, in the purchase of LED lamp, can take a look at the lamp appearance, the lamp body is smooth, there is no scratches, the overall feeling is good, good LED downlight will feel heavy, because the use of the material and the radiator will be better.2, LED will take in the hand shaking force lamp, listen to whether there is noise, such as abnormal sound that no internal fixation downlight, there are security risks, for the unqualified products.3, light LED downlight, using a mobile phone camera function close to the light emitting surface to see whether there are such as flicker, flicker, the LED lamp is equipped with a power supply for the low-end products of inferior quality, affect the overall quality of LED downlight.4, the same LED lights lit up at the same time several manufacturers of the same type lamp, observe its luminous color and brightness is consistent, if not consistent is obvious, as inferior, because the same LED lamp manufacturers with the same type of products can not be light color and brightness inconsistency
Q:Steam more business bathroom bath with what LED lamp?
LED fog lamp, in fact, as long as the structure can reach IP44 level
Q:How to judge the quality of LED downlight
Determine the quality of LED ceiling lamp lighting effect, the United States and Taiwan LED chip chip chip, domestic chip etc.. Different brands, different prices, lighting difference is also large. Special low price downlight, make many use of chip production line down the defective products, color inconsistencies, brightness difference, short service life, users need to pay attention to.
Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
My experience with choosing lights was W, and the bigger the headlight. As far as my family is concerned. All unified outfit is downlight 3W downlight. Open your mouth. It's enough
Q:LED lamp power off why would light up
Is there an indicator on the switch? If it comes down, will it be ok?
Q:Excuse me, how many different sizes for LED lamp lumens
Ha ha, we should consider the problem of heat dissipation, ah, is the light will heat
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:Turn off the lights after the bright LED lamp
Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.
Q:What is the difference between the LED and the LED lamp ceiling lamp
The main difference is in appearance. As Shenzhen City Shengda photoelectric Co. Ltd is specialized in LED indoor lighting products such as LED ceiling lamp, LED lamp, they are the series of the two products to the ceiling. Their use is virtually the same.
Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide
75mm hole, downlight height can be controlled in 3W.5W, height of about 50mm, there is a need to ask me.
