Description

A kind of have arrow beam of light without the LED track spotlight of halation without veiling glare

Technical field

The utility model relates to LED track spotlight, more particularly, relates to and a kind ofly has arrow beam of light without the LED track spotlight of halation without veiling glare.

Background technology

LED track spotlight is also LED track lamp, is that a kind of employing is guide tracked, the shot-light of LED luminescence.Its distinguishing feature can move exactly in orbit, direction of illumination can be changed, be applicable to exhibition room, museum, the light projector of outdoor eaves, edges and corners, the local lighting etc. of the projection of point-like effect, odeum and office, is widely used in the showpiece light of market, high-grade clothing shop and jeweler's shop simultaneously.

As shown in Figure 1, lamp gross weight is less than 3.5 kilograms to existing LED track spotlight outward appearance in the market, and power 42W, peak power can reach 50W, and Luminaire efficiency is greater than 85%.Power acquisition low ripple circuit, power-efficient is greater than 89%, and power factor is greater than 0.9.Working life reaches 30,000 hours.Its structure is mainly as shown in Figure 2: electrical appliance kit 1, universal bar 2, radiator casing 3, COB light source 4, COB support 5, reflector 6, glass cover 8 and front decorative circle 7.

From the optical texture of existing LED track spotlight, it is the combination adopting reflector 6 and glass cover 8, when using reflector 6 and glass cover 8 to be optical system, first heat-conducting silicone grease is coated at COB light source 4 back side, directly be fitted in the inner surface of radiator casing 3, be tightlier locked on radiator casing 3 inner surface by COB support 4.COB support 4 is installed reflector 6, is fixed by the groove of COB support 4, be finally placed in reflector 6 and front decorative circle 7 by glass cover 8, back-off is arranged on the front end of radiator casing 3.Again according to Fig. 4, reflector adopts rotary extrusion aluminum technique, surface adopts anodized, its inner surface is fish scale-shaped minute surface reflector, fish scale-shaped minute surface can by light-ray condensing to required angle, and subsidiary light mixing effect, the bus of reflector is specially designed Bezier, the emergent ray of wide-angle is after reflector reflection, within being gathered in set degree angle (within such as 24 °), other a part of light is then direct from light source outgoing, angle much larger than first retainer (usually more than 30 °), this direct factor that namely hot spot is uneven.

But widely used reflector in the market and the combination of lens, LED light source has the problem such as dazzle, stroboscopic after dressing up light fixture, long-term work in such lighting environment affects the eyesight of people with democratic meeting, although current existing LED light source lamp prodigiosin is applicable to the environment of periphery, but people's long-term operation under such light fixture can not be applicable to, so LED light source is after green illumination, and Healthy Lighting is the trend that it further develops.

Utility model content

For the above-mentioned defect existed in prior art, the purpose of this utility model is to provide a kind ofly has arrow beam of light without the LED track spotlight of halation without veiling glare, the utility model to the control of light more accurately, make most light in effective lighting region, reduce light pollution, dazzle, thus more energy-conservation; Also can eliminate halation, its hot spot sharper keen, be more suitable for accent light application.

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

A kind of have arrow beam of light without the LED track spotlight of halation without veiling glare, comprise electrical appliance kit, universal bar, radiator casing, COB light source and COB support, radiator casing is cylinder, its Internal back end is heat radiator fin, interior forward end is cavity, the junction of Internal back end and interior forward end is provided with a platform, platform is provided with COB light source, COB props up and is set up in COB light source, its one side is in order to push down COB light source, and be screwed on platform, electrical appliance kit is connected with radiator casing rear end by universal bar, also comprise lens, to give out light cup and front decorative circle, give out light one end of cup is connected and fixed on the another side of described COB support, cup inside of giving out light is located at by lens, and be also connected and fixed on the another side of described COB support, the other end of cup of giving out light is connected to front decorative circle one end.

Described lens are the convex lens of circle hat shape, and its convex surface corresponds to the front end of radiator casing.

The described front decorative circle other end is provided with hook, in order to be fixed on the front end of radiator casing.

The outer ring of described front decorative circle is provided with several cavity.

In technique scheme, the utility model has following advantage:

1. the utility model outward appearance adopts general structural member, can replace mutually with prior art, has good compatibility.

2. the utility model to the control of light more accurately, make most light in effective lighting region, reduce light pollution, dazzle, thus more energy-conservation.

3. the utility model can eliminate halation, its hot spot sharper keen, be more suitable for accent light application.
