Advantage of LED Street light with ‘ALG Engine’ Lowest Power consumption compared to other products (nearly half of other LED lights) Our patented ‘Cooling Fin system’ guarantees the LED lights quality over the life span of 50,000 hours as the patented technology keeps cooling the LED lights system most efficiently no matter how the surrounding temperature soars up. It retains almost same luminosity even when it lights the ground of up to ,say, 12m apart from the light source while the luminosity of most of other makers tend to decrease drastically when the LED street lights illuminates the ground of such a distance. The life span is approx. 50,000 hours, which is monumentally big difference from others on the markets. Its weight is very light, almost one-third less than the others, as the casing is made of polycarbonate material instead of die-casting that most of other makers are using. Thus it makes the installation work easy and so much, the installation cost could be lowered. It is designed to be very rugged and strong to any external impacts It is designed to secure perfect water-proof. With such technical superiority and advantages, it does have unrivaled price competitiveness.

5. Technology of ‘ALG Engine’
Our LED Street Light has a unique structure conspicuously distinguished from other similar
products.
— We applied more than 90% of die-cast & patented sheet mounting method using monolithic
structure to maximize thermal efficiency and enhance the assembly process.
1
We used a material with a highest Aluminum content (AL1050) and designed to
maximize thermal performance to achieve maximum heat dissipation rate in the minimum
space.
— We applied the material to be 0.01T ~ 0.2T in order to achieve highest density.
By reducing the weight of the product as little as possible, we lowered the material cost
while maximizing the stability of the LED lights’ luminosity over the life span of
approx. 50,000 hours.
Our Thermal Dissipation technology has got an International Patent.
— The patent we acquired could be applied to other areas like CPU Cooling, Automotive
and household appliances. 4

6. Advantage of ‘ALG Engine’
ALG Engine has ‘One body structure’. Even if conduction rate of heat source is under
50 %, AL1000 thin plate dissipates the heat quickly and efficiently to outside.
1
As ALG Engine applied progressive method using 0.1~0.2T AL1000 materials, the quality is
quite stable and it enables ALG Engine to secure more space for heat conduction by
using 100~ 150 heat radiation Fins.

Thin plate brazing technology protects material from aging and increases the elasticity by
30 % through the protection of the materials from being softened in annealing process.
