20 watts LED bulb E27
LED packaging refers to the sealing of LED chip and welding line, and the connection of power supply, light and heat dissipation, mechanical and environmental protection and shape dimensions.
In the case of the damage of the bulb and the attenuation of the beam output, the integrated beam output is reduced to a specified number of hours.Outdoor light source is 70 %, indoor light source is 80 %.
Light Emitting Diode(LED)
LED is the light-emitting diode,it is a solid light-emitting semiconductor devices, it is the use of solid semiconductor chip as a luminescent material, when both ends with the forward voltage, carrier in the semiconductor compound photon emission and produce Light.LED can directly emit red, yellow, blue, green, green, orange, purple, white light.The first commercial diode was produced in 1960.Its basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, to protect the internal core, so the LED of the seismic performance is good.
