Abstract

The utility model discloses a light-emitting diode (LED) lamp which comprises a heat-dissipating base, a reflecting cover, an LED chip, a substrate used for installing the LED chip, and an installing plate used for installing the substrate. The installing plate is installed on the heat-dissipating base. The reflecting cover is installed on the installing plate through a connecting device. The connecting device can be connected with reflecting covers of different specifications. According to the LED lamp, the installing plate can be connected with the reflecting covers of the different specifications and models, the number of types of the installing plate can be reduced, convenience is brought to production management, expenses of mould opening can be reduced, and production manufacturing cost can be lowered.

Description

A kind of LED light fixture

Technical field

The utility model relates to a kind of LED light fixture.

Background technology

The installing plate that the LED light fixture generally 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, reflection shield is installed on the installing plate; Existing installing plate can only the corresponding reflection shield that a kind of specification is installed, and the installing plate versatility is low, need dispose different installing plates at the reflection shield of different size, make installing plate of a great variety, increase the mould kind, increased manufacturing cost, do not utilized production management.In order to address the above problem, be necessary existing LED light fixture is carried out structural improvement design.

The utility model content

In order to address the above problem, the utility model 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 scheme that its technical problem that solves the utility model adopts 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, and described jockey is set to the form that can be connected with the reflection shield of different size.

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, described projection sidewall is provided with the draw-in groove that cooperates with chimb.

Described draw-in groove is wedge shape.

Described installing plate is provided with some joint pins, and 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 beneficial effects of the utility model are: the utility model is by arranging some groups of set of protrusions at installing plate, make installing plate to 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 reduce manufacturing cost.

The specific embodiment

With reference to Fig. 1～Fig. 5, the utility model 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, and jockey can be connected with the reflection shield 2 of different size model; 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; Projection 61 sidewalls are provided with the draw-in groove 7 that cooperates with chimb 8, have the gap of interting for projection 61 between the chimb 8, and 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 utility model makes installing plate 5 to be connected with the reflection shield 2 of different size by two set of protrusions 6 are set at installing plate, can reduce the kind of installing plate 5, and then reduces the die sinking expense, is convenient to production management, and then reduces manufacturing cost.

Installing plate 5 is as follows with the concrete assembling process of reflection shield 2, earlier chimb 8 is passed the mutual gap between some projections 61, and then contacts with installing plate 5, rotates reflection shield 2 then, makes chimb 8 enter draw-in groove 7, can finish installation process.

As shown in the figure, installing plate 5 other ends are provided with some joint pins 9, and these some joint pins 9 form one for the installing space 10 of placing substrate 4, and this installing space 10 is by cooling base 1 sealing, and substrate 4 is arranged in this installing space 10; Installing plate 5 is connected with cooling base 1 by screw; Installing plate 5 corresponding led chips 3 positions are provided with the through hole that passes through for light.

With reference to Fig. 6, be that reflection shield 2 is installed in the scheme of installation on the inside protrusions group shown in the figure.Certainly, set of protrusions 6 also can be set to three groups, four groups and above quantity in the utility model.

Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replace all is included in the scope that the application's claim sets.
