The GLED's Ω wick consists of an Ω-shaped spiral cathode and an intracavity columnar anode. The GLED-Ω interelectrode combination and coating process described in Publication No. CN101944465A enables electrons to be emitted from the positive halo discharge zone to the hollow cathode discharge. The area is e-spinning motion; mercury ions are generated in the hollow cathode discharge region, and e-spinning discharge is performed in the positive halo discharge region. Both electrons and mercury ions have a long mean free path; this long-moving phase of electrons and mercury ions along the axial direction of the wick allows a large number of mercury atoms to catalyze the emission of ultraviolet light, stimulating a perfectly integrated arc discharge ball. The invention of GLED provides an innovative electric light source with the appearance of an incandescent lamp, the effect of an energy-saving lamp, and the life of an electrodeless lamp.
How to increase the lumen output and improve the light efficiency for the illuminator is obviously a further exploration direction. The interelectrode plasma of the GLED obtains a certain angular momentum due to the imbalance of the axial radiated electric field, and completes the orbital motion of the e-spin. The mean free path between electrons and mercury ions in the wick is a key to determining the strength of the arc discharge ball. How to increase the angular momentum of the plasma and further the mean free path of the long-spinning motion between the poles? Inspired by the mechanism of the planetary magnetic field Lorentz force deflection to achieve the precession motion, the addition of radial magnetic field between the GLED's Ω wick also mentions the development process.
A permanent magnet is placed outside the bulb of the GLED. The lamp body will be awkward and bulky and heavy. The electromagnet is placed outside the bulb of the GLED. The structure of the lamp body will be complicated, and the cost and failure rate will increase. After years of exploration and experimentation, the author believes that it is a practical solution to improve the structure of the Ω spiral cathode.
The Ω spiral cathode of this scheme is composed of opposite spirals on both sides of the middle, as shown in Figure 1:
Figure 1 is a schematic illustration of the helical cathode structure of the present scheme. In Fig. 1, 1 is a spiral cathode on one side, 2 is a spiral cathode on the other side, and 3 is a middle transition ring around a spiral cathode on opposite sides.
The winding direction of the middle side of the existing Ω spiral cathode is the same. The ohmic wick is made of the spiral cathode, and the direct current of the lighting will start from the anode of the lighter, along the anode column to the hot spot near the top of the Ω spiral cathode, at the hot spot. Divided into two sides along the two sides of the Ω spiral cathode back to the negative pole of the lighter. Considering the spiral cathode as the energizing solenoid, the magnetic pole of the same name is formed on both sides of the foot, and it is difficult to establish a radial magnetic field perpendicular to the axial electric field.
The Ω spiral cathode of the solution has opposite spiral directions on the central sides, and the spiral cathode is used to make the Ω wick, and the direct current of the lighting will start from the anode of the lamp, along the anode column to the hot spot near the top of the Ω spiral cathode. At the hot spot, divide the two sides of the Ω spiral cathode back into the negative pole of the lighter. Using the spiral cathode as the energizing solenoid, a different name magnetic pole is formed on both sides of the Ω spiral cathode, and a radial magnetic field perpendicular to the axial electric field can be established. See Figure 2:
2 is a schematic illustration of an ohmic wick made using the spiral cathode of FIG. In Fig. 2, 1 is a spiral cathode on one side, 2 is a spiral cathode on the other side, 3 is a middle transition ring around opposite spiral cathodes; 4, 5 are cathode inner guide wires, and 6 is an anode inner guide. Silk; N, S represent magnetic poles.
The Ω wick shown in Fig. 2 is made by using the spiral cathode shown in Fig. 1. The direct current of the lighting will start from the anode of the illuminator, along the anode column 6 to the hot spot near the top 3 of the Ω spiral cathode, and split into two at the hot spot. The legs 1 and 2 along both sides of the Ω spiral cathode return to the negative pole of the lamp. Since the spiral of the Ω spiral cathode on the two sides of the middle is reversed, the spiral cathode is regarded as a power-on solenoid, and a different name magnetic pole (N, S) is formed on both sides of the foot to establish a radial magnetic field perpendicular to the axial electric field.
The unique feature of this scheme is that an orthogonal electromagnetic field is applied in the interval between the columnar anode and the Ω-shaped spiral cathode. When the electrons leave the cathode hot spot, the mercury ions are generated in addition to the angular momentum obtained in the axially radial electric field. The Lorentz force of the magnetic field is deflected so that the plasma can travel more permanently along the e-spin into the orbit. This greatly increases the chance of the plasma colliding with the working atoms (mercury), thereby further increasing the intensity of the e-spinning discharge under low gas pressure and low inter-electrode voltage conditions.
If the core of ILED is PN junction, then the core of GLED is Ω-Ι junction. The "Ω-Ι junction" is composed of an Ω-shaped spiral cathode and an inner cavity-shaped anode column, and is characterized in that a dome-shaped anode column and an Ω-shaped spiral cathode form a fan-shaped radiation electric field at the top arc; a braided anode The two sides of the column and the Ω-shaped spiral cathode form a symmetric logarithmic electric field; the Ω spiral cathode has opposite spiral directions on both sides of the central portion, and the radial magnetic field is generated on both sides of the Ω-shaped spiral cathode. The plasma in the GLED is the e-spinning discharge that is completed before the combination of these electromagnetic fields.
The LED industry has been struggling, and the competent authorities have mentioned that the idea of ​​replacing incandescent lamps with LEDs should be changed, and lighting companies should create better electric light sources!
In order to let people really use incandescent lamp type fluorescent lamps, this scheme establishes a quadrature electromagnetic field between the wicks, so that GLED can produce high-intensity arc discharge balls, which is obviously a substantial step. In the call to eliminate incandescent lamps, Gas-LED is undoubtedly a wise choice!
Led Tube light
LED tube is commonly known as light tube, daylight tube, its light source using LED as the luminous body. Led tube has many advantages, using led as the light source, light efficiency is higher, more energy saving, longer service life, and more environmental protection. It is generally used for general lighting, office buildings, shopping malls, restaurants, schools, homes, factories and other Indoor Lighting. LED tube can save more than 70% electricity, and its life is more than 10 times that of ordinary light (in theory, it can reach more than 50,000 hours). It does not need to be replaced frequently. At the same time, LED tube has soft light, pure color, which is beneficial to people's vision protection and health.
