Angle Angle emitting arc tube arc tube means to decrease the luminance observation direction normal to the direction of the LED display luminance one-half led, two observation directions and the normal direction of the plane formed by the same angle. Divided into horizontal and vertical viewing. Horizontal viewing angle SMD vertical viewing angle horizontal viewing angle elliptical oval patch of light-emitting tube discharge tube discharge tube discharge tube vertical viewing small size of the LED chip to enhance brightness led television, usually small angle package. The large size of the package does not require a small angle, because it does not require high brightness. So led luminous characters, large angle (110) high-brightness low current is the best. For indoor LED display brightness because of low demand, a wider general audience, so SMD LED is the best option.
