Abstract

The utility model discloses an LED (light-emitting diode) spotlight. The LED spotlight comprises a radiator (1), an outer ring (2) and a housing (8); the lower end of the outer ring (2) is connected with the housing (8); a lamp shade (3), an LED light source (4), a substrate (5) and a pressing ring (6) are sequentially arranged inside the outer ring (2) from the top to the bottom; and the radiator (1) is connected with the outer ring (2) at the position outside the outer ring (2). By adopting the structure that the radiator is connected with the outer ring (2) at the position outside the outer ring (2), namely the radiator is positioned in front of the LED light source, although the LED spotlight disclosed by the utility model is installed at a corner or inside a lamp hole, air circulation near the radiator is relatively good, namely the heat-radiating space is relatively large; the heat radiation of the radiator is sufficient, and the heat on the radiator does not accumulate easily and does not shorten the service life and reduce the light-emitting efficiency of the LED light source; and meanwhile, after the LED light source is overheated, the explosion of the LED light source or the burning of the peripheral wooden ornamental material can be avoided, so a fire disaster and other safety hazards are avoided and the safety is relatively good.

Description

The LED shot-light

Technical field:

The utility model relates to a kind of LED shot-light.

Background technology:

At present, the radiator of the LED shot-light of prior art (being commonly referred to as the GX5.3 shot-light on the market) all is arranged on the rear portion of LED lamp source (being also referred to as light source or lamp pearl), but because the LED shot-light generally all is installed in corner or the lamp hole, then radiator is at the rear portion in LED lamp source, the space of heat radiation is less, and near the air circulation the radiator is relatively poor, be difficult for fully heat radiation, heat gathers easily, and the heat after gathering will influence the service life and the luminous efficiency in LED lamp source, even cause the source explosion of LED lamp or burned around the wooden decorative material and security incidents such as initiation fire, security is relatively poor.

The utility model content:

The utility model at above problem provide service life that a kind of heat can not gather, not influence LED lamp source and luminous efficiency and security LED shot-light preferably.

The utility model overcomes the above problems used technical scheme: a kind of LED shot-light with following structure is provided, it comprises radiator, outer shroud and outer cover, the lower end of described outer shroud is connected with outer cover, once be provided with lampshade, LED lamp source, substrate and pressure ring in the described outer shroud from top to bottom, described radiator is connected with outer shroud in the outside of outer shroud.

After adopting above structure, the utility model compared with prior art, because radiator is connected with outer shroud in the outside of outer shroud, that is to say that radiator is positioned at the front portion in LED lamp source, even then be installed in corner or the lamp hole, near the radiator air circulation is better, promptly San Re space is bigger, helping radiator fully dispels the heat, thereby make the heat on the radiator just be not easy to gather, so the heat on the radiator just can not influence the service life and the luminous efficiency in LED lamp source, simultaneously also with regard to do not exist overheated back LED lamp source explosion or burned around the wooden decorative material and security incidents such as initiation fire, security is better.

As improvement, described radiator and outer shroud are integral structure, and then the radiator of integral structure and outer shroud make that the heat-transfer effect between outer shroud and the radiator is better, be more conducive to outer shroud the heat that LED lamp source produces is transmitted on the radiator, so make that radiating effect of the present utility model is better.

As further improvement, described pressure ring is connected with the outer shroud inner thread, then pressure ring does not need the pressure of outer cover, make substrate more stable, the problem of the loose contact that can prevent effectively that the junction that causes LED lamp source to be connected with driver circuit plate lead because of outer cover is loosening is loosening and then produce is so the problem that the utility model uses is better.

Description of drawings:

Accompanying drawing is the structural representation of the utility model LED shot-light.

As shown in the figure: 1, radiator, 2, outer shroud, 3, lampshade, 4, LED lamp source, 5, substrate, 6, pressure ring, 7, the driver circuit plate, 8, outer cover.

The specific embodiment:

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

A kind of as shown in drawings LED shot-light, it comprises radiator 1, outer shroud 2 and outer cover 8, the lower end of described outer shroud 2 is connected with outer cover 8, be provided with driver circuit plate 7 between described outer shroud 2 and the outer cover 8, once be provided with lampshade 3 in the described outer shroud 2 from top to bottom, LED lamp source 4, substrate 5 and pressure ring 6, the internal diameter of described outer shroud 2 upper ends is less than the external diameter of lampshade 3, the upper surface of described substrate 5 is connected with LED lamp source 4, fit in the upper surface of the lower surface of described substrate 5 and pressure ring 6, described LED lamp source 4 is electrically connected with driver circuit plate 7, the lower surface of described outer cover 8 is provided with two binding posts, these two binding posts are electrically connected with driver circuit plate 7 respectively, and described radiator 1 is connected with outer shroud 2 in the outside of outer shroud 2.

Described radiator 1 is an integral structure with outer shroud 2.

Described pressure ring 6 is connected with outer shroud 2 inner threads.

Assemble method is the method for prior art routine.
