Abstract

The invention discloses an LED lamp comprising a radiating base, a reflector, an LED chip, a substrate for mounting the LED chip and a mounting plate for mounting the substrate. The mounting plate is mounted on the substrate. The reflector is mounted on the mounting plate through a connecting device which can be connected with different types of reflectors. The mounting plate is provided with pressure channels for holding cables. The LED lamp has the advantages that the mounting plate can be connected with the different types of reflectors, so that the types of the mounting plates are less, production and management are convenient, die opening cost is reduced, and production cost is reduced; in addition, the pressure channels in the mounting plate and the radiating base form a cable passage, cables of the lamp are disposed in the cable passage, layout of the cables is optimized, and maintenance is facilitated; through the pressure channels, shedding of the welded cables due to the fact that the cables are pulled from the outside can be avoided effectively.

Summary of the invention

In order to address the above problem, the invention provides a kind of LED light fixture that is provided with the installing plate that can be connected with the different size reflection shield.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of LED light fixture, the installing plate that comprises cooling base, reflection shield, led chip, is used for that the substrate of led chip is installed and is used for installation base plate, described installing plate is installed on the cooling base, described reflection shield is installed on the installing plate by jockey, described jockey is set to the form that can be connected with the reflection shield of different size, is provided with on the described installing plate for the pressuring line groove of placing cable.

Described jockey comprises and is arranged at least two group set of protrusions on the installing plate and is disposed on chimb on the reflection shield, described set of protrusions comprises the some projections that are circular arrangement, the set of protrusions of described at least two groups arranges with one heart, have the gap of interting for projection between the described chimb, be provided with the draw-in groove that cooperates with chimb on the described projection sidewall.

Described draw-in groove is wedge shape.

Be provided with some joint pins on the described installing plate, these some joint pins form an installing space for installation base plate, and described substrate is arranged in this installing space.

Described installing plate is connected with cooling base by screw.

Described set of protrusions is provided with two groups.

Described substrate adopts ceramic material, and described installing plate adopts nonrigid material to make.

The invention has the beneficial effects as follows: the present invention is by arranging some groups of set of protrusions at installing plate, so that installing plate can be connected with the reflection shield of different size, reduced the kind of installing plate, reduced the die sinking expense, be convenient to production management, and then reduction manufacturing cost, simultaneously at installing plate pressuring line groove is set, pressuring line groove is by radiating seat enclosed shape being aligned cable passage, the cable of light fixture is placed in the cable passage, optimized the layout of cable, convenient for maintaining, there is one 90 angle about degree between the outer cable of cable in the pressuring line groove and pressuring line groove, so that the certain frictional force of generation between cable and the pressuring line groove, can effectively prevents from pullling cable from the outside and the cable that causes falls to weld phenomenon.

The specific embodiment

With reference to Fig. 1～Fig. 6, the present invention is a kind of LED light fixture, the installing plate 5 that comprises cooling base 1, reflection shield 2, led chip 3, is used for that the substrate 4 of led chip 3 is installed and is used for installation base plate 4, installing plate 5 is installed on the cooling base 1, reflection shield 2 is installed on the installing plate 5 by jockey, jockey can be connected with the reflection shield 2 of different size model, is provided with on the installing plate 5 for the pressuring line groove 51 of placing cable; Jockey comprises and is arranged on the installing plate 5 two groups of set of protrusions 6 and is disposed on chimb 8 on the reflection shield 2, set of protrusions 6 comprises the some projections 61 that are circular arrangement, these two groups of set of protrusions 6 arrange with one heart, these two groups of set of protrusions 6 comprise inside protrusions group and outside set of protrusions, and reflection shield 2 is installed on the set of protrusions of the outside; Be provided with the draw-in groove 7 that cooperates with chimb 8 on projection 61 sidewalls, have the gap of interting for projection 61 between the chimb 8, draw-in groove 7 is wedge shape, and installing plate 5 can be by the depth adjustment of chimb 8 insertion draw-in grooves 7 with the compactness of reflection shield 2.Substrate 4 adopts ceramic material, and installing plate 5 adopts nonrigid material not crushed with protective substrate 4.The present invention is by arranging two set of protrusions 6 at installing plate, so that installing plate 5 can be connected with the reflection shield 2 of different size, can reduce the kind of installing plate 5, and then minimizing die sinking expense, be convenient to production management, and then reduction manufacturing cost, simultaneously at installing plate 5 pressuring line groove 51 is set, pressuring line groove 51 is by radiating seat 1 enclosed shape being aligned cable passage, the cable of light fixture is placed in the cable passage, optimized the layout of cable, convenient for maintaining, there is one 90 angle about degree between the outer cable of cable in the pressuring line groove 51 and pressuring line groove 51, so that the certain frictional force of generation between cable and the pressuring line groove 51, can effectively prevents from pullling cable from the outside and the cable that causes falls to weld phenomenon.
