Downlights are becoming more and more popular, as one of the modern mainstream lighting fixtures, but not all LED lights are the same. There are two new schools of LED downlights: chip-on-board-COB LEDs,
surface-mount diode-SMD LEDs. Both they produce high-quality light, have a long life span and are extremely efficient.
What is an SMD (Surface Mount Diode) downlight?
SMD downlight is a downlight composed of multiple LED chips. Multiple LED chips are typically mounted on the surface of a circuit board. SMD downlights are more efficient than COB downlights because the light
source produces higher lumens per watt, which means they produce more light at a lower wattage. Usually they only have a fixed angle, they produce a wider beam spread over a larger area. In addition, these lamps
feature frosted lens with larger face plates, that evenly diffuse the light and hide the chip array within the lens. Therefore, the cost is more economical than COB.
SMD LEDs are widely used in home lighting, industrial lighting systems, vehicles, advertising, backlighting and a host of other lighting applications.
COB LED
COB LEDs are the latest and most advanced entrants to the LED market, its performance is the best. The COB downlight with a transparent lens and the COB chips will be exposed. Since all the lights are concentrated
in one area, more powerful cooling capacity is required. So it needs a large radiator to dissipate heat, and these radiators are usually made of aluminum, and it can dissipate heat efficiently and quickly.The large size of the heat sink may result in the cost of COB LEDs downlight being slightly higher than SMD leds downlight.
Our DTE series and DTF series can both be used in SMD and COB. SMD has 2 different reflectors. Different combinations have different effects. You can choose from them!
Downlight DTF COB series has a transparent lens with larger face plates, which transparent lenses can effectively reduce the absorption of light, making the space look brighter and more comfortable.
