Which led light or cob light has a longer service life?

Relatively speaking, the service life of led lights is a little bit longer than that of cob lights. As far as the well-known brands on the market are concerned, cob can maintain a 10% attenuation within 2 years. Of course, these are not guaranteed by some small manufacturers. So when choosing, you need to choose a guaranteed brand, and clearly mark the light decay time of the light source when signing the contract.

In the general description, LEDs can be used for more than 50,000 hours, and some manufacturers advertise that their LEDs can operate for about 100,000 hours. Predictions indicate that high-quality LEDs can maintain more than 60% of the initial lamp brightness after 50,000 hours of continuous operation.

How long is the service life of led lamp beads?

In theory, LED lamp beads can achieve unlimited life, but when applied to lamps, it has a great relationship with heat dissipation and drive current. The greater the junction temperature, the greater the light decay, and the shorter the life. Generally speaking, the service life of led lamp beads is 30,000 to 50,000 hours. In fact, in our daily life, generally the lamp beads used in our led lamps are led lamp beads, so the service life is almost the same.

What is the difference between cob light and led light?

A led lamp is a lamp using light-emitting diodes as a light source. The led is a solid-state semiconductor device that can directly convert electricity into light. The cob light source is the high-efficiency integrated surface light source technology in which the LED chip is directly attached to the high-reflectivity mirror metal substrate. This technology eliminates the concept of the bracket, no electroplating, no reflow soldering, and no patching process, so the process is reduced by nearly a third First, the cost has also been saved by one-third. Generally speaking, it is a lamp that is more advanced and more eye-protecting than the LED lamp.

The difference between the cob lamp and the led lamp is that the led lamp is energy-saving, environmentally friendly, no flicker and no ultraviolet radiation, and the disadvantage is the blue light hazard. The cob lamp has high color rendering, the light color is close to natural color, no flicker, no glare, no electromagnetic radiation, no ultraviolet radiation, infrared radiation, and can protect eyes and skin.

Which is better, COB light or LED light?

The light source of the cob spotlight allows people's eyes to get very good protection, especially the eyes of myopic friends. The daily cost of electricity is small, which saves energy and saves the cost of production and use of electricity. The installation of cob spotlights is very simple and takes less time. The light source of the cob spotlight is the best cob light source at present, and it is also the mainstream trend of the development of the light era in my country at present and in the future.

LED spotlights can be driven by low-voltage direct current: it has the advantages of small load and weak interference, and lower requirements for the use environment. LED spotlights can better control the luminous spectrum composition, which can be well used for local or key lighting in museums and exhibition halls. The luminous directivity of LED spotlights is very strong: the brightness attenuation is much lower than that of traditional light sources, and the price of LED spotlights is civilian.

COB light source is also a kind of LED light source, but it is an integrated packaged LED light source. As for which is better, COB and LED spotlights, although they have their own advantages, the cost of COB light source itself is higher, and the overall heat dissipation performance is better than that of ordinary LED light sources.
