Popular LED chip technology

Lighting efficiency of led downlight, led wall light, or floating light ... depends very much on the quality of the led chip. Currently on the market, all kinds of led lights are mainly produced under 3 following technologies, single chip, SMD chip and COB chip. If you want to know what features they have, don't miss the following article.
Single led chip
This is the most commonly used chip, on bare downlight lamps, with 2 types of light sources 1W and 3W. You can easily buy in any LED store. It is mounted with fixed glue with solder paste, copper foil with extra insulation and aluminum outer cover. However, compared to the two SMD technologies and COB, the single chip is more obsolete, since it is a traditional model. According to experts, in the future, this technology will also be replaced because the characteristics of heat dissipation, material cost and flux reduction are not equal to COB.

SMD CHIP
Types of LEDs using SMD chip as light source 5630, 3014, 3528 ... It is mounted on the printed circuit board and is hidden by the manufacturer behind the light-weight panel or behind the organic glass plate, so that called led panel lamp or led glass. This type of chip technology uses an independent light source to create a common light source, so if the design stage does not guarantee or poor quality manufacturers, there will be overlapping shadows and glare. user.
COB CHIP
Current trends in developed countries often use COB chip technology for led ceiling lights, ceiling lights ... Because it has the advantage of being able to shorten the heat path, reduce heat. return. Because it is directly attached to the heat sink circuit, and the temperature between the chip and the printed circuit is quite small, the heat dissipation is good, thus low luminous flux, improving the life of the ball. Moreover, the light emitted from the COB chip is also milder, more pleasant and subdued than traditional chips at the same capacity. Besides, the COB light source has a wide projection angle, reducing blinding phenomenon, easy to adjust, so it is prioritized for use.
In short, the quality of the led chip is the most influential factor in lighting performance of the lamp. So look for leading reputable manufacturers with long-standing brands to buy, but the price difference is quite large.
