COB lamps are spotlights that use COB light sources as light sources. The cob lamp is a COB (chip on board) chip package, which is a kind of lamp made of bare chip mounting technology. The semiconductor chip is transferred and mounted on the printed circuit board, and the electrical connection between the chip and the substrate is realized by wire stitching. The electrical connection of the substrate is achieved by wire stitching and covered with resin to ensure reliability.

COB lamps are a more popular type of lamp now, which are safer than ordinary incandescent lamps and have a longer service life. At the same time, due to different principles, the light emitted by COB lamps is softer and more comfortable to use.

What are the advantages of cob lamps?

Energy-saving and environmental protection

The power consumption of COB lamps of the same power is only 10% of that of incandescent lamps, which is more energy-saving than fluorescent lamps. Cob lamps are recyclable after disposal, without pollution, unlike fluorescent lamps that contain mercury.

Long service life

COB lamp beads can work for 50,000 hours, which is longer than fluorescent lamps and incandescent lamps. The life of COB lamps that can be switched on and off frequently is calculated according to the time of lighting. Even if they are switched on and off thousands of times per second, the life of LEDs will not be affected.

Adjustable light

The previous dimmers have always been aimed at incandescent lamps, and the light turns red when the incandescent lamps are dimmed; it is difficult to see fluorescent dimmers, which is the main reason why dimming technology has not developed for many years; COB lamps can be dimmed again, and whether it is bright or dim light is the same color (the color temperature is unchanged), which is better than the dimming of incandescent lamps.

High luminous efficiency

The luminous efficiency of high-power cob lamps has exceeded 45lm/W, and because the spectrum of cob lamps is almost entirely concentrated in the visible light band, the light efficiency is far greater than that of incandescent lamps and is catching up with energy-saving lamps and fluorescent lamps.

Rich colors

There are positive white light, warm white light, red, green, blue,, and other colors, whether it is a small lantern or a neon light for decoration next to the headlight in the living room, it is very bright.

Low calorific value

Like spotlights, many 220V spotlights break down after a few days of use because of heat. Although the calorific value of the 12V halogen spotlight is lower than that of the 220V spotlight, its brightness cannot reach the nominal value due to the insufficient power of the transformer. With COB lamps, you can work for a long time without a transformer.
