Description

A kind of vertical LED projector lamp

Technical field

It the utility model is related to light fixture, more particularly to a kind of vertical LED projector lamp.

Background technology

LED lamp is a kind of long-life, specular removal, the light source of energy-conservation, but lamp bead can produce greatly LED lamp when in use Calorimetric amount, thermal accumlation can influence the service life of lamp interior part and circuit, so the radiating of LED lamp bead is an influence The key factor of LED lamp using effect.Existing light fixture effectively can not be radiated using the convection current of air, cause lamp body and LED lamp bead temperature is assembled, and causes the LED lamp bead light decay too fast life-span partially short.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of good heat dissipation effect, and lamp bead uses the longevity Order longer, to be easily installed vertical LED projector lamp.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of vertical LED projector lamp, including lampshade, the lamp bead fixed plate of lampshade front end is sequentially fixed at back to front with before Lid, the bonnet of lampshade rear end is fixed on, the lower end of the bonnet is hinged with mounting seat, and the lampshade is cylindrical housings, described Lamp bead is evenly spaced in lamp bead fixed plate, and the bottom surface of the lampshade is provided with first through hole, the periphery one of the lampshade into The interior radiating that outwards diverging is distributed centered on type has the radiating part of some protrusions, the radiating part to include along some first through hole Piece, in addition to uniformly dispersing some outer fin in adjacent two panels between fin, outer fin with interior fin It is provided with radiation rib.

As the further improvement of such scheme, the outer fin is arranged at intervals with interior fin, the outer fin Length be less than the interior fin length.

As the further improvement of such scheme, a heat shield, the bonnet are fixed with the rear end face of the radiating part It is fixed on the heat shield.

As the further improvement of such scheme, the mounting seat is a frustum housing, the bottom sides of the frustum housing Along locating ring is provided with, positioning through hole is provided with the locating ring.

The beneficial effects of the utility model：

A kind of vertical LED projector lamp of the utility model, include interval integrally formed with radiating part, radiating part in lampshade periphery The outer fin set and interior fin, the heat of lamp bead are passed on radiating part by way of conduction from lampshade, then by outer Fin distributes heat with interior fin to be cooled into air because outer fin with interior fin is spaced sets Put, and outer fin can increase the contact area with air, radiation rib is also with being provided with radiation rib on interior fin The intensity of outer fin and interior fin can be increased, be not easy bending damage so that whole better heat-radiation effect, greatly improve Life-span of LED lamp bead.

Brief description of the drawings

, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain according to these accompanying drawings Other designs and accompanying drawing：

Fig. 1 is the utility model preferred embodiment structural representation；

Fig. 2 is the utility model preferred embodiment decomposing schematic representation；

Fig. 3 is the rearview of the utility model preferred embodiment lampshade.

Embodiment

Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection Enclose.

Referring to figs. 1 to Fig. 3, a kind of vertical LED projector lamp, including lampshade 1, the front end of lampshade 1 is sequentially fixed at back to front Lamp bead fixed plate 4 and protecgulum 2, be fixed on the bonnet 3 of the rear end of lampshade 1, the lower end of the bonnet 3 is hinged with mounting seat 5.

The lampshade 1 is cylindrical housings, and the lamp bead is evenly spaced in lamp bead fixed plate 4, the bottom surface of the lampshade 1 First through hole 11 is provided with, the periphery of the lampshade 1 is integrally formed with the radiating part of some protrusions, the rear end face of the radiating part On be fixed with a heat shield 9, the bonnet 3 is fixed on the heat shield 9, and heat shield 9 can completely cut off the heat of lamp bead, avoid Power supply part in bonnet receives damage, improves the service life of lamp body.

The interior fin 6 that outwards diverging is distributed centered on the radiating part is included along some first through hole 11, in addition to The even some outer fin 7 being dispersed in adjacent two panels between fin 6, outer fin 7 are scattered with being provided with interior fin 6 Hot rib 8.The outer fin 7 is arranged at intervals with interior fin 6, and the length of the outer fin 7 is less than the interior fin 6 Length.

The heat of lamp bead is passed on radiating part by way of conduction from lampshade 1, then passes through outer fin 7 and interior fin Heat is distributed and cooled into air by 6, because outer fin 7 and interior 6 spaced setting of fin, and outer fin 7 is different from the length of interior fin 6 so that space increase between the two, can increase the contact area with air.Outer radiating Piece 7 with being provided with radiation rib 8 on interior fin 6, except increasing heat radiation area think by radiation rib 8, can also increase outer dissipate The intensity of backing 7 and interior fin 6, it is not easy bending damage so that whole better heat-radiation effect, greatly improve LED lamp bead Life-span.

The mounting seat 5 is a frustum housing, and the bottom edge of the frustum housing is provided with locating ring 51, the positioning Positioning through hole 52 is provided with ring 51, mounting seat 5 is that hollow shell can also improve radiating effect, and positioning through hole 52 coordinates fastening Part enables to lamp body to be fixedly secured on position to be installed, and connection is more solid and reliable.

Above is preferred embodiment of the present utility model is illustrated, but the utility model is created and is not limited to The embodiment, those skilled in the art can also make a variety of etc. on the premise of without prejudice to the utility model spirit With modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
