Test of aluminum LED module lighting in the hot water
September 4-7, the 15th China International Optoelectronic Exposition (CIOE) was held in Shenzhen Convention and Exhibition Center. Shenzhen Great Tech LEDs Co.,Ltd carryed the sixth generation project to unveil this CIOE, the exhibition undoubtedly became a major bright spot of light at exhibition, our outdoor SMD LED display with its different from the traditional craft, unparalleled display effect, the scene attracted many exhibitors customer's attention. Our "boiling water experiment", highlights the uniqueness of our products, better heat dissipation and waterproof, customers stopped a long time at the show booth Our patent product - Outdoor Aluminum SMD full color triple and its individual modules can be achieved not only an immersion waterproof effect, and boiled in water can still work, really can do super waterproof, high temperature, to ensure in the outdoor harsh environments and weather conditions.The success of this experiment, the industry proved GTL's success in the outdoor LED display, but also allow customers to be more confident in our products!
The following is the boiling water test:

The video of 0utdoor SMD full-coloredLED screen contrasting with the ordinary ，left for outdoor SMD full color, the right to ordinary diode screen
Left for outdoor SMD full color, the right to ordinary diode screen：
As can be seen from the above video,there is grainy screen contrast in the right and left side of the screen , while the left SMD full color clarity, angle, flatness better if more than a certain distance, the effect is better, basically can achieve high results.
Product testing: LED Display work in the -39.5 degrees environment
Product testing: The video of LED Display work in the -39.5 degrees environment
Detection time: LED Display in -39.5 degrees environment, uninterrupted work seven days (168 hours), to continue its normal operation, no lights appear dead, stop working and so on.
The following is part of the video interception：
Product testing: LED display at a constant temperature of 55 degrees environment
Product testing: work video of the LED display at a constant temperature of 55 degrees environment
Detection time: LED display at a constant temperature of 55 degrees airtight environment, continuous work 10 days (240 hours) without appeared dead lights, stop working and so on.
The following is the LED display at a constant temperature of 55 degrees environment intercepted part of the video:
A major breakthrough in the bottom structure of aluminum mask technology
New Aluminum outdoor full color display module played a decisive role in enhancing the quality of the outdoor SMD full color triple .
Existing SMD outdoor screen display modules are still using the traditional LAMP plastic shell structure process. Years of proven plastic shell long-term outdoor and low temperature environment may cause deformation cracking, fading discoloration, as well as module itself does not have the cooling capacity and other defects. These issues are the performance characteristics of the plastic material itself, and in the long-term outdoor application environment that can not be overcome. Display module SMD plastic shell screen applications continue to prevent further enhance the quality of the SMD display, forming SMD-screen technology development bottleneck.
The division SMD outdoor screen display module masks are made of aluminum material and the bottom mold forming. And thermal conductivity of the Division SMD bracket matching, to achieve the following effects:
1.Aluminum Bottom: Aluminum Bottom Bracket matching with SMD thermal design, heat generated by the SMD chip high thermal conductivity silver metallic (silver thermal conductivity 429w/mk, copper 401w/mk; aluminum 237w/mk; PCB board 16 w / mk) stand directly transmitted to the aluminum pan, and because the chip directly fixed on the bracket, stand in close contact with the aluminum pan (area greater than 5m m) short thermal path, low thermal resistance, heat transfer area, the entire aluminum Bottom are fins LED chip, SMD LED chip inside the heat via the aluminum pan and the temperature distribution of the bottom shell is only slightly higher than that of aluminum, the aluminum pan by changing the cooling conditions of the LED chip temperature can be controlled in a reliable range.
2. Aluminum mask: a special force design and surface treatment makes the PVDF coating aluminum mask to keep the same type within a decade, no fading, no aging, while the mask is modular aluminum outer cooling surface.
