Abstract

The utility model relates to a LED track lamp with high radiating effect, including a radiator, a base plate and a LED light source. The LED light source is installed on the base plate, the lower extreme at the radiator is fixed to the base plate, the radiator is the cylinder, is equipped with a plurality of in the cylinder and is radial fin, is equipped with many heat dissipation leaves on the two sides of fin respectively, and the contained angle between heat dissipation leaf and the fin is lighter than 90, and the radius of every heat dissipation apex tip is greater than heat dissipation leaf root radius. The utility model discloses compare with the radiator in traditional LED track lamp, have following beneficial effect: 1, heat dissipation leaf in the tradition LED track lamp is the right -angle side, the utility model provides a heat dissipation leaf is the hypotenuse, and consequently, the heat radiating area of heat dissipation leaf obviously increases, 2, because the distance of heat dissipation apex tip to radiator axial direction line is greater than the distance of heat dissipation blade root portion to radiator axial direction line, consequently, the thermal current of radiator is directional rationally, the thermal diffusion effect is good.

Description

A kind of LED track lamp with high radiating effect

Technical field

This utility model relates to a kind of LED track lamp, particularly relates to the radiator structure of a kind of LED track lamp, belongs to LED lamp design and manufacturing technology field.

Background technology

LED track lamp is the track lamp with LED as luminous source, pollute because it has radiationless, heavy metal free, the advantage such as color pure, the high and low stroboscopic of luminous efficiency, energy-saving health is widely used in market, car show, bullion, star hotel, brand clothing, high-grade club, blog article thing museum, brand business hall, place such as accent light such as specialty show window, sales counter etc., be to substitute tradition halogen tungsten lamp and replace the perfect light source of Metal halogen lamp.Owing to some special occasions needs the standby stronger brightness of LED track lamp, therefore the power of lamp is the biggest, and this just requires that LED track lamp must have superhigh radiating ability, otherwise will have a strong impact on light decay, causes shorten the service life of lamp.Traditional LED track lamp, one high-power LED light source is provided with on substrate, substrate is fixed on the bottom of radiator, radiator is cylinder, some radial fin it are provided with in cylinder, the two sides of fin is additionally provided with a plurality of heat radiation leaf in arcuation, and the tangent line of heat radiation leaf is vertical with fin.Such heat radiation setting can not make the area of dissipation of radiator be maximum, and therefore, the radiating effect of tradition LED track lamp radiator not yet reaches optimum state, and its light efficiency is still improved space, and light decay is also reduced possibility, and more there are the potentiality of prolongation in service life.

Summary of the invention

In order to more effectively ensure LED track lamp long-term stable operation and control its light decay as far as possible, this utility model provides a kind of LED track lamp with high radiating effect.

This utility model takes techniques below scheme to implement: a kind of LED track lamp with high radiating effect, including a radiator, a substrate and a LED light source, described LED light source is arranged on substrate；Described substrate is fixed on the lower end of radiator；Described radiator is cylinder, is provided with some radial fin in cylinder, and the two sides of fin is respectively equipped with a plurality of heat radiation leaf, it is characterised in that:

Angle between described heat radiation leaf and fin less than 90 °, and heat radiation blade tip end to the distance of radiator longitudinal center line more than the distance of heat radiation blade root to radiator longitudinal center line.

This utility model, compared with the radiator in tradition LED track lamp, has the advantages that

1, the heat radiation leaf in tradition LED track lamp is right-angle side, and the heat radiation leaf in this utility model is hypotenuse, and therefore, the area of dissipation of heat radiation leaf significantly increases；

2, owing to the distance of heat radiation blade tip end to radiator longitudinal center line is more than the blade root distance to radiator longitudinal center line of dispelling the heat, therefore, the hot-fluid of radiator points to rationally, thermal diffusion effect is good.

This utility model has that vane heat dissipating area is big, good heat dissipation effect, and light fixture light efficiency is high, light is weak, the advantage of length in service life.

Accompanying drawing explanation

Accompanying drawing 1 is the main sectional structure schematic diagram of utility model；

Accompanying drawing 2 is Section A-A sectional structure schematic diagram in accompanying drawing 1.

In attached Fig. 1 and 2: 1 radiator, 101 fin, 102 heat radiation leaf, 2 substrates, 3LED light sources.

Detailed description of the invention

Below in conjunction with accompanying drawing this utility model is further explained explanation:

As shown in accompanying drawing 1,2, LED light source 3 is installed on a substrate 2；Substrate 2 is fixed on the lower end of radiator 1；Radiator 1 is cylinder, some radial fin 101 it are provided with in cylinder, a plurality of heat radiation leaf 102 it is respectively equipped with on the two sides of fin 101, angle between heat radiation leaf 102 and fin 101 less than 90 °, and heat radiation leaf 102 point to the distance of radiator 1 longitudinal center line more than the distance of heat radiation leaf 102 root to radiator 1 longitudinal center line.

This utility model by tradition LED track lamp between arc heat radiation leaf tangent line and fin angle be the radiator of 90 °, the angle being arranged to dispel the heat between leaf 102 and fin 101 is less than 90 °, so that the area of dissipation of the heat radiation leaf 102 in this utility model significantly increases, the heat radiation leaf be i.e. equivalent in tradition LED track lamp is right-angle side, and the heat radiation leaf 102 in this utility model is that hypotenuse is the same；This utility model simultaneously by the distance of every heat radiation leaf 102 point to radiator 1 longitudinal center line more than heat radiation leaf 102 root to the distance of radiator 1 longitudinal center line, so that the heat radiation of radiator 1 flows to the most reasonable, thermal diffusion effect more preferably, LED track lamp long-term stable operation more can be effectively ensured and the light of light fixture can be controlled to greatest extent decline.
