Provided is a light emitting diode (LED) spotlight with a lens. The LED spotlight comprises an LED light source assembly, a rear end cover, an LED driver, the lens and a front press cover, wherein a round heat dissipation shell body is in a shape which is big in the front and small at the rear, and the rear end cover is arranged behind the round heat dissipation shell body. The rear end cover is provided with a clamp groove, and the LED driver is arranged in the clamp groove of the rear end cover. The front press cover is clamped on the front end of the round heat dissipation shell body, and the inner diameter of the front press cover is matched with the diameter of the lens. A plurality of first heat dissipation holes are arranged on a ringlike end face of the front press cover, and combined to form a ring shape. The round heat dissipation shell body comprises an inner wall and an outer wall, wherein a heat dissipation air channel is formed in a gap between the inner wall and the outer wall, and a plurality of second heat dissipation holes are arranged on the outer wall. The heat dissipation air channel with two open ends is correspondingly formed between the first heat dissipation holes and the second heat dissipation holes so as to facilitate cross ventilation, and heat generated from the LED light source can be timely conducted out, and efficient heat dissipation is achieved.

Description

LED shot-light with lens

Technical field

The utility model belongs to the LED lighting technical field, is specifically related to a kind of LED shot-light with lens.

Background technology

Led light source is a kind of green light source, compare with incandescent lamp, fluorescent lamp, not only electric energy is high, and to not pollution of environment, its advantage is that the light sources such as traditional incandescent lamp, fluorescent lamp are incomparable, become various form of light source to substitute conventional light source so LED makes more and more at large, for example the LED shot-light with lens is exactly a kind of common led light source.

For example have the LED shot-light with lens now, because front end is equipped with round lens, and round lens will be installed the bore seal of led light source assembly and radiator, therefore the amount of heat of led light source assembly and radiator generation is difficult to timely discharge, radiating effect is poor, affect the service life of LED, also the stability of electrical equipment also exerted an influence.

The utility model content

The technical problems to be solved in the utility model provides a kind of LED shot-light with lens, and it can high efficiency and heat radiation.

For addressing the above problem, the LED shot-light of the utility model band lens comprises circular radiating shell, the led light source assembly, rear end cap, led driver, lens, front gland, circular radiating shell is pre-large post-small shape, rear end cap is installed in the rear of circular radiating shell, rear end cap is provided with draw-in groove, led driver is installed in the draw-in groove of rear end cap, front gland is connected to the front end of circular radiating shell, bottom and the front gland of circular radiating shell are fixedly clamped lens and led light source assembly from fore-and-aft direction, its main feature is, the internal diameter of front gland and the diameter of lens coupling, also offer a plurality of the first louvres on the annular end face of front gland, all first louvres are combined to form annular spread; Described circular radiating shell has inwall and outer wall double-decker, leaves the gap between the inner and outer wall and forms heat dissipation wind channel, offers a plurality of the second louvres on the outer wall.

It is pre-large post-small horn-like that circular radiating shell is.

It is pre-large post-small bowl-shape that circular radiating shell is.

The utlity model has following advantage and effect:

1. the outer double-layer structure design had increased area of dissipation in circular radiating shell adopted, and had increased nearly 1/3 than the radiating surface of traditional LED shot-light; And radiating airflow can form heat dissipation wind channel along the zone, annular gap between the circular radiating shell inner and outer wall, the first louvre and the second louvre lay respectively at the two ends of this heat dissipation channel, be that two, annular gap zone between the inner and outer wall all ventilates, the corresponding heat dissipation wind channel that forms both ends open between the first louvre and the second louvre, more be conducive to air and form convection current, the heat that can in time led light source be sent conducts, realize high efficiency and heat radiation, thereby guarantee well the normal working temperature of LED, greatly prolonged the service life of LED shot-light.
