Abstract
The utility model relates to a lamp, in particular to an LED lamp in a crimping-type structure, which comprises a lamp body, a lamp cup, an LED light source, a lamp cover and a translucent panel; the lamp cup is arranged in the lamp body; the translucent panel is arranged on the front end of the lamp cup; the lamp cover is fixed on the front end of the lamp body and presses the translucent panel; the LED lamp in the crimping-type structure is characterized in that the outer diameter of the front end of the lamp body is an inverted cone with larger front part and smaller rear part; the outer diameter of the lamp cover is bigger than the outer diameter of the front end of the lamp body, and the rear end of the lamp cover is provided with an inverted conical notch with bigger mouth diameter and smaller bottom diameter; and the front end of the lamp body is correspondingly sleeved in the inverted conical notch of the lamp cover, and the two are fixedly connected through riveting. The LED lamp in the crimping-type structure solves the defect of the prior LED lamp that the installation structure of a cover plate and the lamp body affects the cooling performance so that the cooling performance of the lamp is good, so as to further improve the service life of the lamp.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of riveted formula structure LED lamp.
Background technology
Existing its cover plate of LED lamp and lamp body all are to adopt screw to be fastenedly connected mode, and this mode has influenced its heat dispersion, thereby influenced the working life of light fixture to a certain extent because its cover plate and lamp body only for end face contacts, so have limited its area of dissipation.
The utility model content
The purpose of this utility model has solved existing light source because of the mounting structure of pacifying its cover plate and lamp body so that influence the deficiency of heat dispersion, thereby and provides the riveted formula structure LED lamp of the working life that a kind of heat dispersion well further improves light fixture.
The purpose of this utility model is achieved by the following technical solution: a kind of riveted formula structure light source, include lamp body, Lamp cup, led light source, light cover and light-passing board, described Lamp cup is installed in the lamp body, described light-passing board places the front end of Lamp cup, described light cover is fixedly mounted on the front end of lamp body and pushes down light-passing board, it is characterized in that: the front end external diameter of described lamp body is that the place ahead is big, the back taper that the rear is little, the external diameter of described light cover is greater than the front end external diameter of lamp body, and it is big to be provided with mouth diameters in the rear end of light cover, the back taper recess that base diameter is little, the front end of described lamp body is corresponding to be set in the back taper recess of light cover and the two is fixedly connected by riveting.
Further, the exterior angle, rear end of described light cover is an arc chord angle.
Further again, be provided with seal between described light-passing board and the Lamp cup.
Beneficial effect: because the faying face of lamp body and light cover not only has end face, also have all sides, therefore relative with traditional light source, the bonded area of lamp body and light cover is bigger, so heat dispersion is better, and, in manufacture process,, therefore assemble convenient quick owing to do not need to tighten screw.
Description of drawings
Fig. 1 is lamp body and the structural representation of light cover before riveted among the utility model embodiment
Fig. 2 is the A place enlarged drawing of Fig. 1
Fig. 3 is lamp body and the structural representation of light cover after riveted among the utility model embodiment
Fig. 4 is the B place enlarged drawing of Fig. 3
The specific embodiment
Now in conjunction with the accompanying drawings embodiment of the present utility model is further described:
As shown in the figure, the embodiment of a kind of riveted formula of the utility model embodiment structure LED lamp, include lamp body 3, Lamp cup 4, led light source 5, light cover 2 and light-passing board 1, described Lamp cup 4 is installed in the lamp body 3, described light-passing board 1 places the front end of Lamp cup 4, front end 31 external diameters of described lamp body 3 are that the place ahead is big, the back taper that the rear is little, the external diameter of described light cover 2 is greater than the front end external diameter of lamp body 3, and it is big to be provided with mouth diameters in the rear end of light cover 2, the straight little back taper recess 21 in bottom, the front end 31 of described lamp body 3 is corresponding to be set in the back taper recess 21 of light cover 2, thereby by riveting the rear end 21 of light cover 2 is shunk then and tightly hold lamp body 3 tightly, thereby the two is fitted and connected reliably, because lamp body 3 not only has end face with the faying face of light cover 2, also have all sides, therefore relative with traditional light source, lamp body 3 is bigger with the bonded area of light cover 2, binding ability is better, so heat dispersion is better, and, in manufacture process, owing to do not need to tighten screw, only use light cover 2 and lamp body 3 be nested with after again riveting light cover 2 just can easily light cover 2 be installed on the lamp body 3, assembling process is convenient quick.
In the present embodiment, for favourable riveting arranged, the exterior angle, rear end of described light cover 2 is an arc chord angle 22, when riveted light cover 2, utilizes this arc chord angle 22 can make the rear end (being the lower end among the figure) of light cover 2 more utilize contraction like this.
In the diagram, be provided with seal 6 between described light-passing board 1 and the Lamp cup 4.
Obviously; though in conjunction with the accompanying drawings the utility model embodiment has been done detailed description; it only is preferred implementation of the present utility model that but those skilled in the art should be understood that above embodiment; and be not qualification to protection domain of the present utility model, any improvement of being done based on invention spirit of the present utility model is all naturally in the utility model protection domain.
