Speaking of COB lenses, our company's Lianlong Optoelectronics COB lens mold models are relatively complete relative to the industry specifications, let's talk about the principle of COB lenses in the LED industry.
COB LED spotlight is a spotlight that uses COB LED light source as the light source. Traditional spotlight sources mostly use halogen lamps and high-power LEDs. Halogen lamps have low luminous efficiency, relatively power consumption, increased temperature of the irradiated environment, and short service life; while high-power LEDs have local luminous efficiency, uneven spots and dark spots. Place. LED is far superior to traditional lighting products in terms of light-emitting principle, energy saving and environmental protection. And the unidirectionality of LED light forms a perfect support for the light distribution of spotlights.
COB main advantage
1. Energy saving: LED lamps of the same power consume only 10% of the power consumption of incandescent lamps, which is more energy-efficient than fluorescent lamps.
2. Long life: LED lamp beads can work for 50,000 hours, which is longer than fluorescent lamps and incandescent lamps.
3. Dimmable: The previous dimmers have always been aimed at incandescent lamps. When the incandescent lamp is dimmed, the light will turn red; it is difficult to see the fluorescent lamp adjustment
4. Lights, this is the main reason why dimming technology has not been developed for many years; LEDs can be dimmed again, and both bright and dark light are the same color (the color temperature is basically unchanged), which is obviously better than incandescent Dimming of the lamp.
5. It can be switched frequently: The life of the LED is calculated when it is lit, even if it is switched on and off thousands of times per second, it will not affect the life of the LED.
decorations and other occasions that need to turn on and off frequently, LED lights have an absolute advantage.
6. Rich colors: There are various colors such as positive white light, warm white light, red, green, blue, etc., whether it is the small colored lights or neon lights used to decorate the headlights in the living room, they are very bright.
7. Low calorific value: Like spotlights, many 220V spotlights break down after a few days of use because of heat. 12V halogen
COB lens purchase skills
The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardant are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product will have a different design. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
Having said so much, I believe everyone has a little understanding of COB lens principles.
Let’s talk about the advantages of Lianlong Optoelectronics COB. First of all, our company has strict quality requirements. All products meet national and export standards. The products are packaged in anti-static and shock-proof packaging. Secondly, there are many specifications, such as: 35 large lenses, 43 large lenses, 50 large lenses, 60 large lenses, 69 large lenses, 75 large lenses, 95 large lenses, etc. With so many specifications, I believe there must be some that meet your specifications.
