Abstract

The invention provides a heat conduction connector for a lamp and the lamp including the same. The heat conduction connector is provided with a shell and a cavity in the shell, and heat conduction media are arranged in the cavity. When the lamp with the heat conduction connector runs, the heat conduction media transfer heat in the cavity of the heat conduction connector to improve the heat conduction efficiency of the heat conduction connector, so that the emission speed of the heat generated inside the lamp is accelerated, and the problem of difficulty in heat emission of the lamp is solved. Furthermore, as the heat conduction media are filled in the cavity of the heat conduction connector, the whole structure of the heat conduction connector is not influenced and the design method is simple.

Description

technical field [0001] The invention relates to the field of illumination, in particular to a heat-conducting connector for an illuminating lamp and an illuminating lamp comprising the same. Background technique [0002] When the lighting lamp is working, a part of the electric energy will be converted into heat energy, which will cause the entire lighting lamp to heat up. The heat will be dissipated through the shell or a special heat dissipation device, but the heat dissipation effect is still insufficient, which will affect the various components of the lighting lamp. Thereby accelerating the aging speed of each component and shortening the life of the lighting lamp. In particular, the existing LED bulb lamps used to replace traditional incandescent bulbs are required to reach the same level as incandescent bulbs in terms of various parameters, and the parameters in terms of energy saving and environmental protection are much higher than those of incandescent bulbs.
