Problems solved by technology

The shape of the bulb shell is tube-shaped, ring-shaped, etc., and the light-emitting surface is relatively narrow, while the round and rectangular bulb shells that emit light in a large area can withstand a small vacuum pressure. During the process, it is broken due to vibration and the service life is short

Embodiment Construction

[0009] The bulb shell is circular, and the two sides of the bulb shell are outwardly convex arc arch surfaces 1. There are two through holes 2 for placing power couplers on the circular bulb shell, and the two through holes are symmetrically arranged on a diameter of the bulb shell. superior. The power coupler is installed in the two through holes 2 on the circular bulb shell to connect the high-frequency power supply controller.

Abstract

The utility model belongs to technical field of lighting instrument, particularly a round electrodeless lamp comprising of a high frequency power controller, power couplers, a lamp shell and the like, wherein the lamp shell surface is an outwardly convex circular arch, two through holes provided with the power couplers are arranged correspondingly on the same diameter of the lamp shell. The round electrodeless lamp is reasonable and simple in structure, easy to produce, beautiful in appearance, low in manufacturing cost, and good in performance. The outwardly convex circular arch on two sides of the round electrodeless lamp, as well as supporting from walls of two through holes on the round electrodeless lamp enables the round electrodeless lamp to have excellent compressive strength and anti-vibration properties. The round electrodeless lamp has a big luminous surface, the circular arch has a concentrated luminous effect, and accordingly, light illumination is good. The power couplers arranged in the through holes have fast cooling speed, improves luminous efficiency of the round electrodeless lamp, and prolongs service life of the lamp.

Description

technical field [0001] The invention relates to an electrodeless lamp, in particular to a circular bulb structure of the electrodeless lamp, and belongs to the technical field of lighting fixtures. Background technique [0002] High-frequency electrodeless lamps have the characteristics of high luminous efficiency, high color rendering, no flicker, quick start, vibration resistance, energy saving, environmental protection, and easy maintenance, and have been widely used. The existing electrodeless lamp consists of three parts: a high-frequency power supply, a power coupler and a bulb. The inner wall of the bulb shell is coated with fluorescent powder, and the power coupler is composed of a ring magnet fixed on the periphery of a metal core rod and surrounded by a circumferential coil. The shape of the bulb shell is tube-shaped, ring-shaped, etc., and the light-emitting surface is relatively narrow, while the round and rectangular bulb shells that emit light in a large area c...
