Description

The combining structure of light fixture

Technical field

The utility model relates to a kind of combining structure of lighting lamp.

Background technology

The projecting lamp of high power consumption is accompanied by golf calorific value usually, therefore must pay attention to the ventilation effect of field of employment especially, gets rid of fast with the heat that light fixture is produced, and avoids light fixture to burn.Little based on volume, power consumption is few, caloric value is low and the characteristic of long service life, adopt at present much more more and more LED (light emitting diode) as light source with light fixtures such as replacement incandescent lamp bulb, based on halogen bulb.

The radiating mode of golf calorific value light fixture of the prior art, all utilize the metal of excellent in heat dissipation effect to make lamp housing as far as possible, and at lamp housing a plurality of louvres are set, the part heat that bulb produced is distributed by louvre, the part heat is directly absorbed by the metal lamp housing, by air this heat is got rid of again.Another has the light fixture of better radiating effect, then possesses the radiator of a plurality of fins in the lamp body setting, and the plurality of fins expansion endotherm area by this radiator utilizes cross-ventilation that the heat that is absorbed is got rid of, to promote radiating effect again.

Above-mentioned light fixture all is made up of a plurality of module, and for example, lamp socket module, radiating module, light emitting module etc. when making up above-mentioned module, must utilize assemblies such as screw or rivet to fix, so that assembling production efficiency is lower.

The utility model content

The purpose of this utility model is to provide fitting structure a kind of simple in structure, easy to assembly.

In order to address the above problem, the utility model provides a kind of combining structure of light fixture, includes:

One body, the interior space with hollow, the front end of this body is provided with light source base, and the internal diameter of this light source base is provided with internal thread, and the rear end of this body is provided with button hole;

One light source module is located in the light source base of this body front end;

One fixation kit, have a polygonal hole and an ora terminalis, and be used for and the external screw thread of the internal screw-thread screw of described light source base, be provided with convex lens in this polygonal hole, the external screw thread of this fixation kit is locked on the internal thread of described body, utilizes this ora terminalis that this light source module is fixed in the described light source base simultaneously;

One power module;

One lamp holder is provided with trip, after this lamp holder and the combination of described power module, utilizes this trip buckle in the button hole of described body, so that lamp holder and this body are fixed.

In the fitting structure described in the utility model, described light source module includes an aluminium base, and is located at LED and reflecting surface on this aluminium base, and described reflecting surface is the recessed taper periphery around this LED.

In the fitting structure described in the utility model, the periphery of described light source base is connected in the internal diameter periphery of this body with a plurality of fins that are the radiation-like arrangement.

In the fitting structure described in the utility model, when the assembly of combination lamp or module, do not need to use assemblies such as screw, rivet, utilize to fasten and to finish combination with the rotation locking mode, make that the assembling of group tool is more convenient, more efficient, and because of assembly still less, be minimized manufacturing cost.In addition, the front end of light fixture be provided with a plurality of before fin, described before fin be surrounded on the periphery of light source base, can further promote radiating efficiency.

The specific embodiment

Following conjunction with figs. explanation is done more detailed description to embodiment of the present utility model, and any those of ordinary skill in the art can be implemented after understanding the utility model according to this.

As shown in Figures 1 and 2, light fixture provided by the utility model includes a body 1, a lamp holder 2, a power module 21, a light source module 3 and a fixation kit 4; Wherein, body 1 has the interior space 12 of hollow, and the rear end of body 1 is provided with a plurality of button holes 14, and the front end of body is provided with a light source base 10, the periphery of this light source base 10 is provided with a plurality of preceding fins 13 that are the radiation-like arrangement, and preceding fin 13 is connected to the periphery of body 1 internal diameter; The external diameter surface of body 1 also is provided with a plurality of lateral fin sheets 11.Described light source module 3 includes an aluminium base 33, and is located at LED31 (light emitting diode) module on this aluminium base 33, and the aluminium base 33 of LED31 periphery is provided with the reflecting surface 32 that is recessed into taper in being; This light source module 3 directly is installed in the light source base 10, utilizes fixation kit 4 that light source module 3 is fixed in this light source base 10 again.Described fixation kit 4 is a kind ofly to be provided with external screw thread 42 at external diameter, and an end has ora terminalis 44, central authorities have the assembly of convex lens 41, fixation kit 4 inwalls around the described convex lens 41 then form polygonal hole 43, this polygonal hole 43 can cooperate special tool(s) to drive fixation kit 4 rotations, in order to utilize spiral way that external screw thread 42 is combined in the set internal thread of light source base 10 internal diameters, utilize the ora terminalis 44 of fixation kit 4 to prop up the aluminium base 33 of light source module 3 simultaneously, reach light source module 3 is fixed on body 1, and light source module 3 is corresponding to the purpose of convex lens 41.Light source module 3 set lead (not shown) then extend into the interior space of body rear end, to electrically connect with power module 21.When the LED31 electrified light emitting, a part of light can directly penetrate from convex lens 41, and another part light then can be penetrated by convex lens 41 by these reflecting surface 32 reflections again.In other words, the utility model cooperates the fixation kit 4 that is provided with convex lens 4 by light source module 3, is obtained reverberation, receives light and controls the function that light penetrates angle, makes the projection performance of light more outstanding.
