Technical Characteristics

Heat protection techniques for electrical and independent circuits

An LED is about eight times more efficient than a filament light bulb but it can be heated up by the heat consumption and the ohm resistance inside the device. If an LED driver is closely located to the multiple LED lamps, then it must be able to withstand the high ambient temperature.

To satisfy such environmental requirements, H-MAX has successfully developed a 0.38 static current driver to provide the max efficiency of more than 98%. Since the internal power consumption in the driver is so low that it can operate in full load conditions despite the high ambient temperature of 60 degrees or higher. Our technical staff has the world best current control technology to successfully rule out the causes for over current and improve the product’s safety.

In addition, the separate designs of the SMPS and the CONTROL _DRIVER achieves a more efficient structure to discharge the heat from the device and at the same time this independent circuit heat protection technology prevents the interactions of heats that cause mutual rises in the temperature.

H-MAX heat sink

Its heat protection ability can maintain the LED device’s surface temperature at about 40°. When turning on the lamp, the heats from the LED device is released quickly through the metal PCB and the accurately attached heat sink distributes the heat to the air.

In addition, the H-MAX heat sink has fine wrinkles in each groove to maximize the surface area size and minimize a reduction in the LED’s lifetime caused by the heat.

H-MAX lens

The lenses used for the H-MAX products are the results of R&D works for more than one year.

The existing LED lenses have narrow angles that can’t expand the light source fully and they are very expensive. As the angle is expanded, the rate of expansion is reduced. If the pressure is slightly changed while molding the lens, the rate of transparency is dropped. To make a product that can withstand the heat and temperature and still have a good rate of transparency, we have gone through so many trials and errors to adjust the ratio and the design.

In addition, since the molding works is done at high pressure, we had to repeatedly make the molds for thirteen times before completing the final lens product.

As a result, although the existing LED lens with 30 to 40 degrees can increase the intensity level by 4 to 5 times, our H-MAX lens with 60 degrees can increase the intensity levels by more than 12 times.

If our lens is not applied, then a 100W class LED lamp can have an intensity level of 30lux at 10 meters away. However, by using our H-MAX lamp, a 20W product can generate an intensity level of 50 lux or higher at 10 meters away. Compared to the Japanese products with the same class, this is 2.5 times higher.

※ In case of APEXLED-P8, by mounting this lens, the intensity level can be improved to 80 lux at 8meters. Converting this figure into the height of 12 meters, then it turns out to be about 35 lux. Considering that a 300MW streetlamp is about 30 lux from 12 meters, this figure is quite high.
