Description

Led lamp

[technical field]

The utility model is about a kind of light fixture, refers in particular to and adopts the manner fastening person who is easy to dismounting between its lampshade and the radiating fin.

[background technology]

Constantly rise in energy cost, and under the surging background of environmental protection demand, can expect to see and use the existing lighting of the lower white heat bulb of energy conversion efficiency, with gradually by using light emitting diode to be replaced as the light-emitting diode (LED) illuminating lamp that light source possesses the low and long service life of power consumption or the like advantage as light source.

Referring to shown in Figure 3, be the led lamp of a prior art, it consists predominantly of a radiating seat 61, a lampshade 62 and a light emitting diode module 63, wherein this radiating seat 61 is made up of

several fins

611,62 on this lampshade is arranged on the radiating seat 61, and this light emitting diode module 63 has several light emitting diodes 631, it is arranged on the radiating seat 61 and is positioned at lampshade 62, can be subjected to power drives and luminous, and light is to penetrate lampshade 62 to penetrate, and the heat that produces when luminous is then dispersed by radiating seat 61.

The light fixture of aforesaid prior art, its lampshade 62 is to be fixed on the radiating seat 61 in bonding mode, yet, adopt bonding mode just must use viscose glue and many steps that is coated with viscose glue together, therefore assemble on the processing procedure comparatively complicated, and the lampshade after bonding 62 is dismounting voluntarily more just, and causing in the future, light fixture is difficult to maintain and clean.

[utility model content]

Because the shortcoming that the led lamp of aforementioned prior art exists, the utility model is its structure of improvement, makes that lampshade is a detachable, and expectation can solve this shortcoming.

For reaching above-mentioned creation purpose, the employed technological means of the utility model is to provide a kind of led lamp, and it includes:

One radiating seat, it has several fins, and those fins are arranged in the form of a ring, are concaved with a catching groove on the lateral border of an end of each fin;

One lampshade, it has a ring-like opening, and convexes with a profile in adjacent this opening part on the inner peripheral surface, and lampshade is to cover on the radiating seat with opening part, and profile is incorporated in the catching groove of each fin;

One light emitting diode module, it is arranged on the radiating seat and is positioned at lampshade.

Above-mentioned led lamp can further include a supporting seat, and it is arranged on the described radiating seat and interfixes with each fin respectively, and described light emitting diode module is to be arranged on this supporting seat.

Above-mentioned led lamp can further include a collar, and is concaved with an annular groove with respect to the profile place on the outer peripheral face of described lampshade, and this collar is sheathed in the annular groove.

The utility model provides a kind of led lamp in addition, and it includes:

One radiating seat, it has several fins, and those fins are arranged in the form of a ring, convex with a profile on the lateral border of an end of each fin;

One lampshade, it has a ring-like opening, and is concaved with a catching groove in adjacent this opening part on the inner peripheral surface, and lampshade is to cover on the radiating seat with opening part, and the profile of each fin is incorporated in the catching groove;

Above-mentioned led lamp can further include a collar, and is concaved with an annular groove with respect to the catching groove place on the outer peripheral face of described lampshade, and this collar is sheathed in the annular groove.

Led lamp of the present utility model, owing between its lampshade and each fin being mutually combines by profile and catching groove to be arranged on the radiating seat, make profile disengaging catching groove just lampshade can be pulled down as long as therefore force in lampshade, otherwise, make profile buckle in the catching groove again and just can put in back lampshade, hence one can see that, and the utility model is convenient to dismounting owing to this lampshade, therefore have the comparatively complicated shortcoming of assembling processing procedure because of the employing viscose glue is bonding except the light fixture that can solve prior art, can also be convenient to maintain and clean.

[specific embodiment]

Referring to Figure 1 and Figure 2, led lamp of the present utility model, it includes a radiating seat 10, a lampshade 20, a collar 30, a supporting seat 40 and a light emitting diode module 50, because feature of the present utility model mainly is the combination between this lampshade 20 and the radiating seat 10, therefore non-part about this combination repeats no more herein on the structure of aforementioned each element.

This radiating seat 10 has several fins 11, and those fins 11 are arranged in the form of a ring, is concaved with a catching groove 111 on the lateral border of an end of each fin 11.

This lampshade 20 is the light-permeable material, has a ring-like opening 21, and convex with a profile 22 in adjacent these opening 21 places on the inner peripheral surface, and be concaved with an annular groove 23 with respect to profile 22 places on the outer peripheral face, lampshade 20 is to cover on the radiating seat 10 with opening 21 places, and profile 22 buckles in the catching groove 111 that is incorporated into each fin 11.

This collar 30 is sheathed in the annular groove 23 of lampshade 20.

This supporting seat 40 is arranged on the described radiating seat 10, is positioned at an end that is formed with catching groove 111 on each fin 11, and supporting seat 40 interfixes with each fin 11 respectively.

This light emitting diode module 50 is arranged on the supporting seat 40 and is positioned at lampshade, and it has a substrate 51 and is arranged on several light emitting diodes 52 on this substrate 51.

By as can be known aforementioned, the utility model is to buckle in the mode of catching groove 111 by profile 22, make lampshade 20 can remain on the radiating seat 10, the described collar 30 then can avoid lampshade 20 to come off easily, when desiring to pull down lampshade 20, make profile 22 break away from catching groove 111 as long as force in lampshade 20, otherwise, reinstall lampshade 20 and make profile 22 buckle in the catching groove 111, lampshade 20 just can not come off.

In addition, the position of described profile and catching groove also can be exchanged mutually, that is on the lateral border of an end of each fin of radiating seat, be to convex with a profile, and being concaved with a catching groove on the inner peripheral surface of lampshade, this embodiment and previous embodiment can reach the purpose that is fixed on radiating seat that makes the lampshade detachable equally.

In sum, led lamp of the present utility model, because its lampshade 20 is convenient to dismounting, therefore carry out the maintenance and the cleaning of light emitting diode module 50 easily, the light fixture that while the utility model also can solve prior art has the comparatively complicated shortcoming of assembling processing procedure because of the employing viscose glue is bonding.
