Problems solved by technology
[0006] In order to overcome the difficult problem of heat dissipation of the existing electrodeless lamp bulb, the object of the present invention is to provide a heat-dissipating electrodeless lamp bulb. Using this bulb, the electrodeless lamp does not need to dissipate heat by increasing the heat dissipation metal area of the lamp holder, and it can dissipate the heat from the electrodeless lamp. The heat generated by the lamp is dissipated in a timely manner, thereby prolonging the service life of the electrodeless lamp, reducing the manufacturing cost of the electrodeless lamp, and eliminating the technical obstacles to the promotion and application of the electrodeless lamp in a large area

Embodiment 1
[0013] Example 1: figure 1 Shown is an electrodeless lamp equipped with a heat-dissipating electrodeless lamp bulb, which consists of three parts: a power generator, a power coupler, and a heat-dissipating electrodeless lamp bulb. The heat-dissipating electrodeless lamp bulb includes a glass outer bulb 1, a sealed vacuum Chamber 2 and induction coil installation chamber 3. The airtight vacuum chamber 2 is composed of glass outer bulb 1 and induction coil installation chamber 3. The induction coil installation chamber 3 is a straight tube with two ends open. The induction coil is set in the induction coil installation chamber. In the cavity 3, in the finished electrodeless lamp, the upper end of the induction coil installation cavity 3 communicates with the outside world.

Disclosed is a bulb for a heat-dissipating nonpolar lamp, which comprises a glass bulb housing, a sealed vacuum cavity and an inductive coil installation cavity. The sealed vacuum cavity is made up by the glass bulb housing and the inductive coil installation cavity, and the upper end of the inductive coil installation cavity is communicated with the outside. The invention changes the bulb of a conventional nonpolar lamp by replacing the open inductive coil installation cavity with a sealed inductive coil installation cavity and enables the inductive coil installation cavity to communicate with the outside, so heat generated by the inductive coil inside the inductive coil installation cavity can be directly dissipated to the outside. According actual detection, the nonpolar lamp with such a bulb is excellent in heat dissipation effect. If a 115 W nonpolar lamp continuously works for 3hours, the temperature of the heat-dissipating nonpolar lamp is below 40 DEG C, 10 to 20 DEG C lower than that of a common nonpolar lamp. Therefore, the bulb improves the heat dissipation performance of the nonpolar lamp.
Description
technical field [0001] The invention relates to a high-frequency or low-frequency electrodeless lamp, in particular to a bulb of the electrodeless lamp. Background technique [0002] With the in-depth implementation of the national energy-saving policy, a continuous wave of innovation has been set off in the lighting industry. As the latest energy-saving lighting appliance, the electrodeless lamp has come out. It is a brand-new lighting lamp. It consists of a power generator, a power coupler It is composed of three parts with the electrodeless light bulb. The power generator acts on the induction coil of the power coupler. The electromagnetic field generated by the induction coil excites the plasma gas discharge in the vacuum airtight cavity of the bulb, and converts electrical energy into light and heat. Since the electrodeless lamp has the advantages of extremely high light efficiency, high color rendering, long life, no flicker, energy saving and environmental protection,...
