Professional Custom Lamp Holder Accessories Manufacturer

Semiconductor light-emitting diode light bulbs with shade, cover, light assembly, screw lamp holder. Light-emitting module having a circuit board, are mounted on the circuit board in series with the at least two vertical light emitting diode emitting diode set, the light emitting diode in series with a resistor, the light emitting component and the negative electrode lead, respectively, and the screw lead the mouth of the bottom electrode and the cap screw cap wall connected to the electrodes, characterized in that said light emitting diode set in the number of light emitting diodes are at least two different height positions. Thus, the emission angle of light increases, the brightness uniformity, brightness enhancement, effectively overcome the shortcomings of light emitting diode way. After testing, it works reliably. Furthermore, the housing has a side wall of the screw and the negative lead on its inner screw cap connected to it with a more reliable one card line groove. Thus, by tightening screw allows the negative lead screw lamp socket to connect, its work is more reliable.
