Problems solved by technology

[0005] In the present invention, the glass bulb is made into a structure with a coupling cavity penetrating through the center, and the heat conduction rods protrude from both ends of the coupling cavity, so that both ends of the coupling cavity can dissipate heat, and the heat dissipation is better, and the two ends of the heat conduction rod can be connected to other radiators. Its one end can also be the same as the prior art, connected to the metal lamp holder, and the other end connected to the metal lampshade. The lampshade has a large area, and the entire lampshade can become a radiator of the coupling cavity, which can play a good heat dissipation effect. The glass bulb can also be made It is spherical or pear-shaped; compared with the prior art, the heat dissipation of the present invention is good, which solves the problem that the power of the high-frequency electrodeless lamp is limited due to poor heat dissipation of the coupling cavity, and can be made into a high-power high-power lamp with a power of more than 200W. Frequency electrodeless lamp, coupling chamber temperature can drop to 50-80 ℃

Abstract

The invention discloses a high-frequency electrodeless lamp in the technical field of lighting devices, which comprises a glass bulb, wherein an indium screen and amalgam are enveloped in the glass bulb, a coupling cavity is arranged on the glass bulb, a coupling coil is arranged in the coupling cavity, and is wound on the periphery of a magnetic core tube, a heat conducting stick is inserted into the magnetic core tube, the coupling cavity passes through the glass shell, and the heat conducting stick are extended out from the two ends of the coupling cavity. The invention solves the problem of power restrain of the high-frequency electrodeless lamp caused by the poor heat radiation of the coupling cavity, has more excellent heat radiation as the two ends of the coupling cavity both can disperse heat, and can be produced into a large power high-frequency electrodeless lamp with over 200W power, and the temperature of the coupling cavity can reduce to 50-80 DEG C. The electric light source can be used for the lighting in various places.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a high-frequency electrodeless lamp. Background technique [0002] The high-frequency electrodeless lamp is to inductively couple the high-frequency electromagnetic energy into the bulb, so that the avalanche ionization of the gas in the bulb forms a plasma. The powder is excited by ultraviolet light to emit visible light. The high-frequency electrodeless lamp is an electric light source based on the combination of the two principles of fluorescent lamp gas discharge and high-frequency electromagnetic induction. The structure of the existing high-frequency electrodeless lamp mainly includes a spherical or pear-shaped glass bulb, and one end of the glass bulb is inward. Concave to form a coupling cavity with a single-ended opening. Indium mesh and amalgam are encapsulated in the glass bulb. A coupling coil is arranged in the coupling cavity. The coupling coil is wound around the outer ci...
