LED lamps and lanterns of optical performance:

LED lamps and lanterns of optical performance: overall droop: 10000 h light failure is less than 10% ( Maintain light output rate of more than 90%) More than 15%, 50000 h droop ( Maintain light output rate of more than 85%) Service life: 50000 hours or more ( Excluding drive power supply) 。 Efficiency of lamps and lanterns: p

LED optical performance of lamps and lanterns: integral droop: 10000 h light failure is less than 10% ( Maintain light output rate of more than 90%) , LED street lamp, 50000 h light failure is less than 15% ( Maintain light output rate of more than 85%) Service life: 50000 hours or more ( Excluding drive power supply) 。 Efficiency of lamps and lanterns: 80% or more ( Output flux of lamps and lanterns is not less than 80% of encapsulated device output flux) 。 Give full play to the characteristics of the integrated chip encapsulation, through the optical design, according to different needs, equipped with different convex curve, rely on the lens to the light distribution in different directions, of the light Angle can reach 120 ° ~ 160 °, small light can be gathered within 30 °, can satisfy the demands of different occasions lighting.
