Problems solved by technology

[0003] High-frequency electrodeless lamps have been widely welcomed by the market for their high brightness and low energy consumption since their launch. They can be widely used in street lights, factory lights, stadium lights, display lights and household lights. The heat source, one is the power generator and the other is the power coupler, which will generate a lot of heat during the working process, and the heat dissipation problem of the high-frequency electrodeless lamp has not been well solved at present, so if the wattage of the high-frequency electrodeless lamp If it is too high, it will seriously affect its service life
Therefore, the wattage of high-frequency electrodeless lamps is difficult to break through 200 watts, which restricts the development of high-frequency electrodeless lamps and becomes a bottleneck for manufacturers of high-frequency electrodeless lamps.

Embodiment 1

[0024] Please also refer to figure 1 , figure 2 and image 3 , as shown in the figure, no cooling holes are opened on the base of the first coupler, and no cooling holes are opened on the base of the second coupler.

Embodiment 2

[0026] Please also refer to figure 1 , figure 2 and Figure 4 , as shown in the figure, a cooling hole is opened on the first coupler base, and a cooling hole 11 is also opened on the second coupler base. By providing heat dissipation holes on the bases of the two couplers, air convection can be formed in the holes, which is more conducive to heat dissipation.

[0027] exist Figure 1 to Figure 4 based on the Figure 5 , is a high-frequency electrodeless lamp using a bidirectional high-frequency electrodeless lamp bulb, wherein two sets of power generators are used, the first coupler 4 is connected to the first power generator 12 through the power connection line 10; the second coupler 8 is connected to the first power supply generator 12 through the power connection line 10 is connected to the second power generator 13.

[0028] In the high-frequency electrodeless lamp made by the present invention, two couplers are arranged in the cavity of the bulb bulb, and the effec...

Abstract

The invention provides a bidirectional high-frequency electrodeless lamp bulb. The bulb comprises a bulb shell, wherein the bulb further comprises a cavity and a discharge cavity, wherein the cavity is used for accommodating a coupler; an exciter is arranged in the discharge cavity; the cavity penetrates through the upper end and the lower end of the bulb shell; the coupler comprises a first coupler and a second coupler, wherein the first coupler is arranged at the upper end of the bulb shell; and the second coupler is arranged at the lower end of the bulb shell. In the bulb, the cavity is designed to penetrate through the upper end and the lower end of the high-frequency electrodeless lamp bulb, so that both the upper end and the lower end can be provided with a power coupler and each power coupler can respectively connect a power generator, which fulfills the aim of realizing a high-wattage high-frequency electrodeless lamp by a combination of two low-wattage couplers, and breaks through the production bottleneck of the high-frequency electrodeless lamp.

Description

technical field [0001] The invention relates to a high-frequency electrodeless lamp bulb, in particular to a high-frequency electrodeless lamp bulb with a bidirectional structure. The invention also relates to a high-frequency electrodeless lamp using a bidirectional high-frequency electrodeless lamp bulb. Background technique [0002] High Frequency Electronic Discharge Lamp (High Frequency Electronic Discharge Lamp) consists of three parts: light bulb, power coupler and power generator (also called electronic ballast for electrodeless lamp). After a certain range of power supply voltage is input, the power generator generates a high-frequency constant voltage above 2MHz and sends it to the power coupler. The coupler is installed in the bulb and connected to the electronic ballast of the electrodeless lamp through a connecting line. A strong electrostatic magnetic field is established in the discharge space of the bulb, and the gas in the bulb is avalanche ionized to form ...
