Light source fixing structure and portable lamp

Abstract

The invention relates to a light source fixing structure and a portable lamp, wherein the light source fixing structure comprises a fixing seat, wherein the fixing seat is connected with a light source fixing end, a vibration absorption elastic sheet is arranged on the fixing seat, is formed by bending and folding an elastic rod and comprises a middle section, a front section and a back section, the front section and the back section are connected with two ends of the middle section, the middle section is provided with a bending and folding part, the bending and folding part tightly presses the upper surface of the light source fixing end, the free ends of the front section and the back section are respectively provided with a hook part capable of being reversely hooked on the fixing seat, and an included angle alpha between one hook part and the corresponding front section or the back section is smaller than 70 degrees. After the light source fixing structure provided by the invention is adopted, the buffer effect can be at least realized in the vertical direction and the horizontal direction, a light source is protected, the vibration absorption elastic sheet can also realize a certain buffer effect on the vibration absorption elastic sheet in other directions, and the all-position protection on the light source is realized. In addition, the light source fixing structure is simple, and the lamp tube mounting and dismounting is convenient.

Description

technical field [0001] The invention relates to the technical field of lighting, and more specifically, to a light source fixing structure and a portable lamp. Background technique [0002] In the currently used lamps, the light source is generally fixed on the base body by plugging and unplugging. It is convenient to replace the light source with this structure, but the anti-seismic performance of the lamp is not good enough. When the luminaire is dropped or subjected to other vibrations, the light source will be damaged by a large impact, resulting in a short lifespan of the luminaire. Especially some portable lamps, because they often need to be carried and used, are often subject to vibration, and their light sources need to be protected. [0003] In the prior art, in order to realize the anti-vibration performance of the lamp, the lamp holder is generally fixed on the housing by using a vibration-damping rubber pad. For example, the invention patent with the applicati...

Problems solved by technology

[0004] In the above solution, the main part of the vibration damping device is between the lamp holder and the housing, or between the lamp holder and the bracket that fixes the lamp holder. Although it can play a certain buffering effect on the lamp, it cannot be very good. Protects tubes mounted on sockets, especially long tubes that are more susceptible to vibration
