Description

Combination structure of lamps and lanterns

technical field

The utility model relates to a combined structure of a lamp, in particular to a combined structure of a lamp for lighting.

Background technique

Projector lamps with high power consumption are usually accompanied by high heat generation, so special attention must be paid to the ventilation effect of the place of use, so as to quickly remove the heat generated by the lamps and prevent lamps from burning out. Based on the characteristics of small size, low power consumption, low heat generation and long service life, LEDs (light-emitting diodes) have been increasingly used as light sources to replace incandescent bulbs, halogen bulbs and other lamps.

The heat dissipation methods of high-calorie lamps in the prior art all try to use the metal with good heat dissipation effect to make the lamp housing, and set a plurality of heat dissipation holes in the lamp housing. Part of the heat generated by the bulb is dissipated through the heat dissipation holes, and part of the heat is directly absorbed by the metal. The lamp housing absorbs the heat, and the air removes the heat. Another type of lamp with better heat dissipation effect is to install a heat sink with multiple fins on the lamp body, and expand the heat absorption area through the majority of fins of the heat sink, and then use air convection to remove the absorbed heat, so that Improve cooling effect.

Existing lamps are composed of a plurality of modules, such as a lamp base module, a heat dissipation module, a light emitting module, etc. When assembling the above modules, screws or rivets must be used to fix them, so that the assembly production efficiency is low.

Utility model content

The purpose of the utility model is to provide a light assembly structure with simple structure and convenient assembly.

The lamp assembly structure described in the utility model includes a body, a light source module, a lampshade, a circuit module, a lamp holder and a lamp holder, wherein the body has a hollow inner space, and the rear end of the body is provided with a convex The end face of the flange is provided with at least one V-shaped groove; the light source module is arranged at the front end of the body; the lampshade is combined at the front end of the body, and the light source module is enclosed between the lampshade and the body; the circuit The module is set in the body; the inner diameter of the front end of the lamp holder is provided with a V-shaped guide post corresponding to the aforementioned V-shaped groove, and a plurality of tenons that can be embedded in the flange, and the rear end of the lamp holder is provided with a conductive external thread.

Through the guidance of the V-shaped guide post and the V-shaped groove, the lamp holder and the body can be quickly matched, and then the tenon and the flange can be smoothly fitted and fixed; It is screwed with the external thread of the lamp holder to be electrically connected, and the external thread provided on the lamp holder can be screwed with the conductive part of the power supply.

The lamp combination structure described in the utility model does not need to use components such as screws and rivets in the assembly of the lamp, but can be assembled by using a fastening method. Therefore, the assembly of the utility model is more efficient, and because the components are more less, to reduce manufacturing costs.
