Olivary electrodeless lamp

Abstract

The invention relates to an olivary electrodeless lamp which belongs to the technical field of lighting fixtures. The olivary electrodeless lamp comprises a spherical bulb casing, a lamp cap, a coupler and a controller, wherein the center of the spherical bulb casing is provided with a main hole which is perforated up and down, a longitudinal heat radiation groove is arranged on the inner wall of the main hole, the upper end and the lower end of the spherical bulb casing are provided with 2-6 heat radiation holes which are communicated with the main hole, the coupler is arranged in the main hole in the center of the spherical bulb casing and is installed and connected on the lamp cap, and holes corresponding to the heat radiation holes at the lower end of the spherical bulb casing are arranged on the lamp cap. The invention has reasonable and simple structure, easy production and manufacture, low cost, convenient installation, energy conservation, environmental protection, easy maintenance, good heat radiation effect and long service life. Heat generated by the electrodeless lamp is quickly emitted out by the main hole in the center of the spherical bulb casing and the heat radiation holes communicated with the main hole, the temperature of the electrodeless lamp is effectively lowered, the light efficiency of the electrodeless lamp is enhanced, and the service life of the electrodeless lamp is prolonged.

Description

technical field [0001] The invention relates to an electrodeless lamp, in particular to a heat dissipation structure on a bulb of an electrodeless lamp, and belongs to the technical field of lighting fixtures. Background technique [0002] Electrodeless lamps have the advantages of high light efficiency, high color rendering, no flicker, quick start, shock resistance, energy saving and environmental protection, and easy maintenance. In recent years, the application of electrodeless lamps has attracted more and more attention. The existing bulb-shaped electrodeless lamp is generally composed of a bulb shell, a lamp holder, a coupler and a controller, etc., and a concave cavity is arranged in the center of the bulb shell. The coupler composed of body magnetic core, coil and copper rod is set in the center of the concave cavity of the bulb shell. The coupler is connected with the lamp cap. The heat after the bulb works is mainly dissipated by the copper rod to the lamp cap. 80%...

The existing bulb-shaped electrodeless lamp is generally composed of a bulb shell, a lamp holder, a coupler and a controller. The center of the bulb shell is provided with a concave cavity. The coupler composed of body magnetic core, coil and copper rod is set in the center of the concave cavity of the bulb shell, and the coupler is connected with the lamp cap. The heat after the bulb works is mainly dissipated by the copper rod to the lamp cap. 80% of the heat is in the The temperature of the inner cavity of the bulb and the lamp head will be very high, especially for high-power electrodeless lamps, the heat will be particularly serious, which will affect the use effect and life of the electrodeless lamps. The market urgently needs a spherical electrodeless lamp with high heat dissipation performance
