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.

LED light output will vary with its chip type, packaging method and other differences. But there is no uniform standard to measure its brightness in the world. Generally speaking, the total luminous amount of LED is measured by the height of a light point in the axial direction, and is represented by (MCD) candles. A LED with a very high degree value does not mean that its light output is very high. To calculate its total light output, you must take its luminous angle into account.

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.
