Description

A kind of New LED COB shot-light

Technical field

The utility model relates to a kind of shot-light, relates in particular to a kind of LED COB shot-light.

Background technology

Shot-light generally comprises the base and the radiator that are fixed together, be fixed on light source in radiator, cover at lens on light source, be arranged at the driving power in base, existing spotlight light source generally adopts Halogen lamp LED or many large-power LED light beads, and lens are fixed on radiator by the mode of spinning.Halogen lamp LED energy consumption is large, not environmental protection, and many large-power LED light beads are attached to and easily break gold thread on aluminium base, thereby fraction defective is high, and thermal resistance is large, is unfavorable for heat radiation, in addition, traditional aluminium base is directly fixed on radiator, then by radiator, heat is dispersed in air and is gone, thereby the structure of radiator has material impact to heat dispersion; And by spinning mode fixed lens, make lens easily be pressed onto light source, in not gathering.

Utility model content

The purpose of this utility model is to provide a kind of New LED COB shot-light, and light source adopts single integrated optical source COB lamp pearl, utilize jump ring fixed lens, and heat dispersion is good.

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

A New LED COB shot-light, comprises base, is arranged at driving power, lower end and the end in base

The radiator that seat is fixedly connected with, be integrally formed at the erecting bed in radiator sidewall, be arranged at the COB support on erecting bed, be fixed on single integrated optical source COB lamp pearl of COB support, cover is penetrated the lens on COB lamp pearl, also comprise a jump ring, described erecting bed and radiator sidewall form an opening up accommodation space, described COB support, COB lamp pearl, lens and jump ring are all arranged in described accommodation space, and described jump ring is arranged at lens upper end, the arranged outside of described radiator sidewall has fin, this fin becomes whirlwind type along heat dissipation lateral wall array.

The inwall of described radiator sidewall is formed with one for the depression that jump ring is installed, and described depression is arranged at lens top, and size is less than the diameter of jump ring.

Described radiator sidewall top is formed with a stretch flange formability toward in, described jump ring is arranged at described extension

Between flange lower end and lens tip.

The top of described radiator sidewall is higher than fin top.

Outer, described fin upper end is formed with an extending edge outward.

Described radiator is screwed and is connected with base.

The beneficial effects of the utility model are: adopt single integrated optical source COB lamp pearl, can make the assembling of lamp pearl simple, thermal resistance is little, and good heat dissipation is lighted photochromic high conformity, but also can intersperse decorative environment; Adopt jump ring fixed lens, thus can avoid lens overwhelm light source poly-in; The funnel-shaped radiator of whirlwind, utilizes the principle of chimney, strengthens natural air heat loss through convection mode, makes heat dispersion better.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As Fig. 1, 2, 3, shown in 4, the utility model LED COB shot-light comprises the base 1 and radiator 2 being fixed together, be arranged at the driving power 3 in base 1, be integrally formed at the erecting bed 4 in radiator sidewall 21, be arranged at the COB support 5 on erecting bed 4, be fixed on single integrated optical source COB lamp pearl 6 of COB support 5, cover is penetrated the lens 7 on COB lamp pearl 6, also comprise a jump ring 8, described erecting bed 4 forms an opening up accommodation space 22 with radiator sidewall 21, described COB support 5, COB lamp pearl 6, lens 7 and jump ring 8 are all arranged in described accommodation space 22, and described jump ring 8 is arranged at lens 7 upper ends, by the elastic force of jump ring 8, jump ring 8 is relative with radiator sidewall 21 fixing, thereby jump ring 8 is fixing by lens 7.

Described radiator sidewall 21 arranged outside have fin 23, this fin 23 becomes whirlwind type along radiator sidewall 21 arrays, thereby this radiator 2 forms a cyclone type chimney, after the heat that COB lamp pearl 6 is distributed passes on fin 23, utilize the principle of chimney, the upper and lower convection current of air between fin 23 between two, that is to say and strengthened natural air heat loss through convection mode, thereby make heat dispersion better.In the present embodiment, preferably, described fin 23 outers, upper end are formed with an extending edge 24 outward.

In the present embodiment, the top of described radiator sidewall 21 is higher than fin 23 tops.Preferably, the inwall of described radiator sidewall 21 is formed with one for the depression 25 that jump ring 8 is installed, and described depression 25 is arranged at lens 7 tops, and size is less than the diameter of jump ring 8.When thereby jump ring 8 is installed, jump ring 8 parts are positioned at depression 25, a part is positioned at outside depression 25, thereby the part that jump ring 8 is positioned at outside depression 25 can be pushed down lens 7, thereby fixed lens 7, depression 25 arrange can more convenient jump ring 8 installation, and can avoid jump ring 8 move up and down or directly spin off.In other embodiments, can be also that radiator sidewall 21 tops are formed with a stretch flange formability (not shown) toward in, described jump ring 8 is arranged between described stretch flange formability lower end and lens 7 tops.Adopt jump ring 8 fixed lens 7, thereby can avoid lens 7 to be pressed onto light source and in poly-.

In the present embodiment, because adopted single integrated optical source COB lamp pearl 6, thereby make the assembling of lamp pearl simple, thermal resistance is little, and good heat dissipation is lighted photochromic high conformity, but also can intersperse decorative environment.

In the present embodiment, preferably, described radiator 2 is fixedly connected with by screw 9 with base 1, and the fixing mode of screw 9 makes radiator 2 in the installation and removal process of whole lamp be not easy to separate with base 1, thereby can avoid driving power 3 to expose the potential safety hazard of bringing.
