CN202629668U - LED (Light Emitting Diode) spotlight - Google Patents

Abstract

The utility model discloses an LED (Light Emitting Diode) spotlight, which comprises a power connector and a long taper-shaped radiator, wherein the power connector and the radiator are in threaded connection; and the radiator is provided therein with an annular heat dissipation piece, a wide voltage driver, an LED lamp set, a heat dissipation plate, an optical lens and a clamping ring. As the long taper-shaped radiator is adopted, heat generated by the LED lamp set can be effectively transferred outward, and as the LED lamp set is a cold light source, the LED lamp set does not cause any pollution to the environment. Compared with a filament lamp, the LED spotlight has the advantages that the power saving efficiency of the LED spotlight can reach over 90%, and for the same brightness, the electric power consumption of the LED spotlight is only one tenth of that of a common filament lamp and half of that of a fluorescent tube.

Description

A kind of LED shot-light

Technical field

The utility model relates to the LED lighting engineering, more particularly relates to a kind of LED shot-light.

Background technology

In daily life and work, generally adopt traditional incandescent lamp to do shot-light, but incandescent lamp exist energy consumption high, can not frequent starting, defective such as can turn black and can break down very soon.The LED lamp not only can overcome above-mentioned defective, and since the factors such as the recyclable utilization again of assembling parts of nuisance such as the LED lamp is not mercurous and LED lamp, very environmental protection.The voltage range of LED lamp is very wide, but from the equal operate as normal of 85～260v, is applicable to whole world domestic power grid voltage, and can arbitrarily changes brightness, thereby reach comfortable energy-saving effect.But existing shot-light generally all adopts the great power LED shot-light, if distributing that the heat that the great power LED shot-light produces can not be instant, will be very easily aging, influence service life.

The utility model content

To the defective that exists in the prior art, the purpose of the utility model provides a kind of LED shot-light.

For achieving the above object, the utility model adopts following technical scheme:

A kind of LED shot-light; The radiator that comprises power connection and long taper; Said power connection is threaded with radiator, is provided with annular radiating piece, wide voltage driver, LED lamp group, heat sink, optical lens and pressure ring in the said radiator, and said annular radiating piece is connected fixing with power connection; One end of said wide voltage driver passes annular radiating piece and links to each other with power connection, and the other end of said wide voltage driver passes heat sink and links to each other with LED lamp group; Said LED lamp is mounted on the heat sink, and the side face of said heat sink also leans on the inner chamber of radiator mutually; Said optical lens is located at the lamp holder side of LED lamp group, and the one side of said optical lens offsets with LED lamp group, and the another side and the pressure ring of said optical lens offset; Said pressure ring is fixedly connected with the inner chamber outer end of radiator.

The outside of said radiator is provided with radiating fin.

Said annular radiating piece comprises the heat-conducting type plastic casing, is provided with the heat conduction aluminium sheet in the said heat-conducting type plastic casing.

Said radiator comprises the heat-conducting type plastic casing, is provided with the heat conduction aluminium sheet in the said heat-conducting type plastic casing.

Compared with prior art; A kind of LED shot-light of the utility model; The radiator that comprises power connection and long taper; Said power connection is threaded with radiator, is provided with annular radiating piece, wide voltage driver, LED lamp group, heat sink, optical lens and pressure ring in the said radiator, and said annular radiating piece is connected fixing with power connection; One end of said wide voltage driver passes annular radiating piece and links to each other with power connection, and the other end of said wide voltage driver passes heat sink and links to each other with LED lamp group; Said LED lamp is mounted on the heat sink, and the side face of said heat sink also leans on the inner chamber of radiator mutually; Said optical lens is located at the lamp holder side of LED lamp group, and the one side of said optical lens offsets with LED lamp group, and the another side and the pressure ring of said optical lens offset; Said pressure ring is fixedly connected with the inner chamber outer end of radiator.Because adopted the radiator of long taper, the heat that can effectively LED lamp group be produced passes, and LED lamp group is cold light source, and self has no pollution to environment.Compare with incandescent lamp, electric energy can reach more than 90%, and under same brightness, power consumption is merely 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube.If replace 50% of our present traditional lighting with LED, annual China saves the summation that electric weight is equivalent to power station, Three Gorges generated energy, and its energy-saving benefit is considerable.Moreover the LED lamp is a kind of green light source, and LED lamp DC driven does not have stroboscopic; Do not have infrared and composition ultraviolet, do not have radiation pollution, colour rendering is high, and very strong light emission direction property is arranged; Light modulation property is good, and colour temperature can not produce the collimation error when changing yet, and the cold light source caloric value is low; Can safe touch, these all are that incandescent lamp and fluorescent lamp are inaccessible.It can provide the illumination space of comfortable, is well positioned to meet people's physiological health demand again, is the healthy light source of vision protection and environmental protection.
