The viewing angle of the LED is also a function of the LED chip type and the light splitting or scattering function of its epoxy resin shell. LEDs of different chips and packages will have different brightness values. If two LEDs have the same brightness value, the larger the luminous angle is, the greater the light output is.

Environmental LED is made of non-toxic materials. Unlike fluorescent lamps, which contain mercury, it will cause pollution. At the same time, LED can also be recycled. Durable LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to be damaged.
