3528 Green SMD LED in the circuit and equipment as a light, or composed of text or digital display
We supply kinds of 3528 SMD LED with different wavelength from 365nm to 1550nm, which include the visible LED and the invisible LED.In this catalog, we mainly introduce the 3528 Green Smd LED.
In this catalog, we mainly introduce the 3528 Green SMD LED of visible light. 3528 SMD LED , size is 3.0*3.6mm. For this Green SMD LED, we can package with single chip 3528 SMD LED or 2 chips 3528 SMD LED and the power can be 0.06W 3528 Green SMD LED, 0.1W 3528 Green SMD LED, 0.2W 3528 Green SMD LED, 0.5W 3528 Green SMD LED, 0.6W 3528 Green SMD LED, 0.8W 3528 Green SMD LED, 1W 3528 Green SMD LED, 3W 3528 Green SMD LED and so on.
There have two kinds of the voltage on this green SMD LED: 1.8-2.5V and the 2.8-3.5V. The voltage of yellow-green SMD LED( 560nm LED -575nm LED) is 1.8-2.5V, they are not the normal product, but they do can't be ignored. Most of the Green SMD LED's voltage are 2.8-3.5V, like 3528 lime SMD LED, 3528 green SMD LED.
3528 Green SMD LED is deeply loved by their users because of the small size, the high bightnes and 3528 Green SMD LED have the cooling copper at the bottom, which can make the product to get out of the heat in time.
It is often used in LED lighting, LED Lamps , LED backlight, LED panel lights, LED furniture, landscape LED, LED Lighting, LED Lighting, led Backlight, LED Panel Light, LED Furniture, LED Photo Light, LED Aperture, LED Toys, grow light LED, fill light LED, LED aperture and other lighting products.
In addition, this 3528 Red SMD LED have the angle like the through-hole LED so it belongs to the spotlight SMD LED. It have a len on the top of the SMD LED, which can make this 3528 SMD LED with angle like 30 degrees, 60 degrees.
