Abstract

The utility model discloses an LED ceiling spot lamp, which comprise a lampshade and a lamp body, wherein the lamp body comprises a lamp housing, and a diversion base integrally connected with the lamp housing, wherein the diversion base is fixedly provided with a hot base plate, the hot base plate is fixedly provided with an LED lamp panel, the center of the diversion base, which corresponds to the center of the hot base plate, is provided with a heat-dissipating hole, a plurality of diversion grooves are distributed in a diffusing way from the heat-dissipating hole to the periphery, a position of the side wall of the lamp housing, which corresponds to a cavity between the LED lamp panel and the diversion base, is provided with a plurality of pores, and the a position of the lamp housing, which is positioned at the rear part of the heat-dissipating hole, is provided with air holes. The design structure of the utility model enables the heat generated by the LED light panel to be quickly dissipated through the diversion structure of a heat-dissipating base, the dissipation efficiency is good, not only the problem of heat dissipation of the existing high-power LED can be solved, but also the size of the lamp with the same power is greatly reduced, the weight thereof is lightened, and the replacing problem between the utility model and the existing LED ceiling spot lamp body is solved.

Description

A kind of LED smallpox shot-light

Technical field

The utility model relates to a kind of Ceiling light, especially a kind of LED smallpox shot-light.

Background technology

Along with the development of new light sources technology, led light source is low in energy consumption because of it, the extremely market favor of the characteristic of long service life, is applied in lighting field more and more widely.Though led light source has the incomparable advantage of conventional light source, the thing followed is how to solve this light source heating and heat dissipation problem in use, and especially for the high-power LED light source, its heating problem is more outstanding.

The smallpox shot-light of existing conventional light source, comprise lamp body and lampshade, lamp body is movably connected in the lamp body seat, and existing led light source is to rely on the bigger fin of volume to realize dispelling the heat, power is big more, and the fin volume that needs is just big more, and the lamp body that can not substitute traditional smallpox shot-light light source is installed in the lamp body seat, therefore, limited the application of led light source on this type Ceiling light.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides that a kind of volume is little, good heat dissipation effect, the LED smallpox shot-light that can substitute with existing smallpox shot-light.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of LED smallpox shot-light, comprise lampshade and lamp body, it is characterized in that: described lamp body comprises that lamp housing reaches and the integrated diversion seat of lamp housing, be fixed with hot substrate on the described diversion seat, be fixed with the LED tabula rasa on the hot substrate, the diversion seat center corresponding with described hot substrate center is provided with louvre, be divergent shape from this louvre to periphery and be distributed with a plurality of diversion grooves, cavity place between corresponding LED tabula rasa of described lamp housing sidewall and the diversion seat has a plurality of pores, is positioned at the louvre rear portion on the described lamp housing and has air-vent.

As further improvement in the technical proposal, the circumference that described diversion seat is positioned at the diversion groove afterbody sinks to forming the water conservancy diversion ventilating groove.

As further improvement in the technical proposal, described lamp body diversion seat rear portion is fixedly connected with the distribution chamber, and described air-vent is positioned on the described distribution chamber.

The beneficial effects of the utility model are: in the utility model lamp body the design of diversion seat make heat that the LED tabula rasa produces can be fast flow-guiding structure by diversion seat loose, good heat dissipation effect, not only solved the heat dissipation problem of existing great power LED, and the light fixture of same power, the volume of radiator dwindles greatly, weight saving has solved the substitution problem with existing smallpox shot-light lamp body.

Description of drawings

Following accompanying drawing further specifies the utility model.

Fig. 3 is a broken away view of the present utility model;

Fig. 4 is the stereogram of diversion seat.

The specific embodiment

With reference to Fig. 1～Fig. 4, a kind of LED smallpox shot-light, comprise lampshade 1 and lamp body 2, described lamp body 2 comprises that lamp housing 21 reaches and the integrated diversion seat 22 of lamp housing, be fixed with hot substrate 4 on the described diversion seat 22, be fixed with LED tabula rasa 3 on the hot substrate 4, diversion seat 22 centers corresponding with described hot substrate 4 centers are provided with louvre 222, be divergent shape from this louvre 222 to periphery and be distributed with a plurality of diversion grooves 221, the cavity place between corresponding LED tabula rasa 3 of described lamp housing 21 sidewalls and the diversion seat 22 has a plurality of pores 23.

Adopt the flow-guiding structure design of the utility model diversion seat 22, when LED tabula rasa 3 adstante febres, hot substrate 4 temperature raise, and edge's heat distributes soon, and the middle part is difficult for heat radiation, thereby the formation temperature difference, the negative pressure that this temperature difference produces sucks the pore 23 of cold airflow from lamp housing 21 sidewalls, flows to center louvre 222 through diversion groove 221, arrives the center temperature and edges up, cold airflow constantly replenishes into from pore 23, rises to 6 discharges of lamp housing air-vent thereby promote thermal current from centre bore 222.Air-flow constantly flows in flow-guiding channel in the entire heat dissipation process; form an air conducting system; become passive heat radiation and be active heat removal; constantly take away the heat of hot substrate; radiating efficiency improves greatly; the temperature of LED tabula rasa also is unlikely to rise too high, thereby helps protecting light source, increases the service life.When the power of LED tabula rasa is big more, this temperature difference is just big more, also helps forming flow conductance more, and the raising of radiating efficiency is obvious more.

In the present embodiment, a plurality of diversion grooves 221 adopt M shape to disperse distribution; More help the air-flow circulation in order to make, the circumference that described diversion seat 22 is positioned at diversion groove 221 afterbodys sinks to forming water conservancy diversion ventilating groove 223.

As preferred implementation of the present utility model, fixedly connected distribution chamber, diversion seat 22 rear portions 3, described air-vent 6 is positioned on the distribution chamber.

The design of diversion seat in the utility model lamp body so that the heat that the LED tabula rasa produces can be fast flow-guiding structure by diversion seat loose, good heat dissipation effect, not only solved the heat dissipation problem of existing great power LED, and the light fixture of same power, the volume of radiator dwindles greatly, weight saving has solved the substitution problem with existing smallpox shot-light lamp body.
