Abstract

The utility model discloses an LED spotlight with a heat conduction convection channel. The LED spotlight comprises a lamp base, a radiator, an LED light source, a driver, a lens and the like, wherein the top of the radiator is connected with the lamp base, the lens is fixedly installed at the bottom of the radiator, the LED light source is installed inside the radiator and connected with the lamp base through the driver, a plurality of radiating fins are distributed on the outer surface of the radiator, a first radiating hole is formed in the bottom between every two adjacent radiating fins, second radiating holes corresponding to the first radiating holes are formed in the edge of the lens, and the heat conduction convection channel for air flowing is formed by the first radiating holes, the second radiating holes and the radiating fins. Heat generated by the LED light source is conducted to the radiator, the heat conduction convection channel is formed in the outer surface of the radiator, the heat on the radiator is taken away through cold air flowing in the heat conduction convection channel from bottom to top, convection is formed, the temperature of the LED spotlight is accordingly reduced, the light-emitting efficiency is improved, and the service life of the LED spotlight is prolonged.

Description

A kind of LED shot-light with thermal convection passage

Technical field

The utility model relates to a kind of LED shot-light, particularly relates to a kind of LED shot-light with thermal convection passage.

Background technology

LED light emitting diode is because advantages such as its life-span is long, light efficiency is high, radiationless and low-power consumption, in lighting field, use more and more frequently, LED shot-light is one of light fixture of manufacturing using LED light emitting diode as light source, the shape of its structure and traditional bulb lamp is basic identical, for avoiding waste the energy and reducing costs, so the LED shot-light of manufacturing at present, is all to use lens and the airtight cooperation of radiator, the problem that such design exists is: the heat that light source produces is not easy to distribute.

In view of this, the inventor studies this, develops specially a kind of LED shot-light with thermal convection passage, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of LED shot-light with thermal convection passage, effectively promotes the inside and outside cold-hot air convection of shot-light, increases substantially heat-sinking capability and the luminous efficiency of shot-light.

To achieve these goals, solution of the present utility model is:

A kind of LED shot-light with thermal convection passage, comprise lamp holder, radiator, LED light source, driver and lens etc., wherein, the top of radiator is connected with lamp holder, lens are fixedly mounted on the bottom of radiator, LED light source is arranged on radiator inside, and be connected with lamp holder by driver, on the outer surface of described radiator, be distributed with several radiating fins, bottom between adjacent two radiating fins is provided with the first louvre, the edge of lens is provided with second louvre corresponding with the first louvre, the first louvre, the second louvre and radiating fin form the thermal convection passage for Air Flow.

As preferably, described radiator is hemispherical, the rounded bottom of radiator is provided with the outer annular broadside edge arranging on one day, radiating fin is evenly distributed on radiator, bottom is connected along upper surface with annular broadside, the first louvre correspondence is arranged on broadside along upper, and connects annular broadside along upper and lower surface.

As preferably, the edge of said lens is an annular plastic assembly, is evenly provided with and the first louvre the second louvre one to one on described plastic assembly.

As preferably, the top of above-mentioned radiator is further provided with several through holes, for the discharge of hot-air in radiator.

When the above-mentioned LED shot-light work with thermal convection passage, the heat that LED light source produces is transmitted to radiator, because radiator outer surface is provided with thermal convection passage, in thermal convection passage, cold air is from below to up taken away the heat on radiator, form convection current, thereby reduce the temperature of LED shot-light, improve luminous efficiency, increase the service life of LED shot-light.

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is the LED shot-light structure exploded view of the present embodiment;

Fig. 2 is the LED shot-light heat radiation schematic diagram (arrow is airflow direction) of the present embodiment.

The specific embodiment

As shown in Figure 1, a kind of LED shot-light with thermal convection passage, comprise lamp holder 1, radiator 2, LED light source 3, driver 4 and lens 5 etc., wherein, the top of radiator 2 is connected with lamp holder 1, lens 5 are fixedly mounted on the bottom of radiator 2, and LED light source 3 is arranged on radiator 2 inside, and are connected with lamp holder 1 by driver 4.Described radiator 2 is hemispherical, on the outer surface of radiator 2, be evenly distributed with several radiating fins 21, bottom between adjacent two radiating fins 21 is provided with the first louvre 22, the rounded bottom of radiator 2 is provided with the annular broadside of outer setting on one day along 23, the bottom of radiating fin 21 is connected along 23 upper surfaces with annular broadside, the first louvre 22 correspondences are arranged on broadside along on 23, and connect annular broadside along 23 upper and lower surfaces.The edge of described lens 5 is an annular plastic assembly 51, is evenly provided with and the first louvre 22 the second louvre 52 one to one on described plastic assembly 51.The first louvre 22, the second louvre 52 form with radiating fin 21 the thermal convection passage that supplies Air Flow.

In the present embodiment, the top of above-mentioned radiator 2 is further provided with several through holes, for the discharge of radiator 2 interior hot-airs.

As shown in Figure 2, when the above-mentioned LED shot-light work with thermal convection passage, the heat that LED light source 3 produces is transmitted to radiator 2, because radiator 2 outer surfaces are provided with thermal convection passage, in thermal convection passage, cold air is from below to up taken away the heat on radiator 2, forms convection current, thereby reduces the temperature of LED shot-light, improve luminous efficiency, increase the service life of LED shot-light.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
