White phosphor mixture for LED components

The United States of New York provided the blue / green lighting system, which comprises a light emitting diode and has at least two emission peak wavelength of the at least one light emitting material, wherein at least two emission peaks of CIE emission color coordinates in CIE chromaticity diagram of the five edge region. The lighting system can be used as a green signal lamp for traffic signals. The luminescent material may be a mixture of phosphors. The utility model relates to an energy-saving lamp with a lampshade, which belongs to the technical field of the lamp tube of Zhejiang. It includes a lamp tube and the lamp in the lamp, outside the lampshade, the lamp holder is fixed on the upper part of the lampshade, which solves the problems of high manufacturing cost existing in the prior art, the lamp tube transport and sales process vulnerable or not concentrated beam etc.. The utility model has the advantages of simple structure, reasonable design, low manufacturing cost, and the light tube is not easy to be damaged in the course of transportation and sale. Improved annular fluorescent tube bender China Zhejiang the utility model relates to an improved bender for circular fluorescent lamp tube, which is characterized in that a control circuit of electromagnetic valve are respectively arranged on the gas pipeline and the oxygen pipe, the valve before the solenoid valve in the pipeline and respectively connected with a time relay, and parallel in the control circuit, time control and time relay for 0.5-5 seconds. Bending machine is implemented according to the scheme, because the heater is not burning state in no lamp heating, thus saving gas and oxygen, the saving rate can reach 25%-30%; second is to improve the tube outer surface finish and flatness to avoid defects and adhesion.
