A kind of novel large-power LED lighting

[technical field]

The utility model relates to a kind of high-power LED lighting fixture.

[background technology]

In recent years, high-power LED lighting fixture particularly adopts the integrated super-high-power LED light source of single COB as lighting and the lighting module of luminaire, obtains the approval of society and increasingly extensive application with the advantage of the aspects such as its efficient energy-saving, environmental protection, safety and reliability height, long service life.But, because the LED luminaire can produce a large amount of heats in electrified light emitting, as can not timely and effectively dispelling the heat, will affect stability and the service life of LED luminaire.Therefore, the quality of cooling system design will be related to luminous efficiency, luminous intensity distribution quality and the service life of high-power LED lighting fixture integral body.

The utility model is exactly to make in view of the situation.

[utility model content]

The utility model has overcome the deficiencies in the prior art, and a kind of high-power LED lighting fixture of simple in structure, good heat dissipation effect is provided.

The utility model is for solving the problems of the technologies described above, by the following technical solutions:

A kind of novel large-power LED lighting, it is characterized in that including substrate, end at substrate is provided with heat pipe, the other end is provided with LED lamp source, be provided with a plurality of radiating fins along the heat pipe annular spread at described heat pipe, the center of described heat pipe is corresponding with the center in LED lamp source.

Aforesaid a kind of novel large-power LED lighting, it is characterized in that upper side edge, outer side edges, lower side at radiating fin are respectively equipped with tabs, lower tabs, outer flap, at the corresponding buckle that is provided with in outer end upper and lower, outer flap, the button hole that the buckle that is provided with adjacent radiating fin in inner end upper and lower, outer flap can snap in.

Aforesaid a kind of novel large-power LED lighting is characterized in that described lower tabs is trapezoidal shape, and the length of trapezoidal upper base is less than trapezoidal length of going to the bottom.

Aforesaid a kind of novel large-power LED lighting, but it is characterized in that being equipped with increasing heat radiation area and preventing from hindering the flanging of hand in the inner side edge of radiating fin and outer side edges.

Aforesaid a kind of novel large-power LED lighting is characterized in that described lower tabs outer end and lower side arc-shaped transition.

Aforesaid a kind of novel large-power LED lighting is characterized in that being provided with a plurality of convection holes at described radiating fin.

The utility model compared with prior art has following advantage:

The utility model adopts heat pipe, be provided with a plurality of radiating fins along the heat pipe annular spread at described heat pipe, end at described heat pipe is provided with substrate, be provided with LED lamp source at substrate, the structure that the center of heat pipe is corresponding with the center in LED lamp source, the heat in LED lamp source can be directly delivered on the heat pipe by substrate, by heat pipe heat is delivered on the radiating fin again, mode with convection current is distributed in the air, therefore, it is higher that the utility model and traditional LED lamp source heat-dissipating device are compared radiating efficiency, weight is lighter, thereby has further improved total quality and the security of light fixture.

In addition, be provided with tabs, flanging and the second flanging at radiating fin, increased the area of dissipation of radiator, and because fin is thinner and sharper, flanging and the second flanging is set prevents that when installing and using fin from cutting hand.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is elaborated:

A kind of novel large-power LED lighting, include substrate 3, end at substrate 3 is provided with heat pipe 1, the other end is provided with LED lamp source 4, be provided with a plurality of radiating fins 2 along heat pipe 1 annular spread at described heat pipe 1, the center of described heat pipe 1 is corresponding with the center in LED lamp source 4.Because the center of heat pipe 1 is corresponding with the center in LED lamp source 4, when LED lamp source 4 produces heat, energy very first time heat output pass to heat pipe 1, is delivered to rapidly on the radiating fin 2 by heat pipe 1 heat is evenly spread out again, and has improved radiating efficiency.

Upper side edge 41 at radiating fin 2, outer side edges 42, be respectively equipped with tabs 21 on the lower side 43, lower tabs 22, outer flap 23, described upper tabs 21, lower tabs 22, outer flap 23 can be fixed the position of 2 of adjacent two radiating fins when connecting, make 2 of radiating fins keep certain spacing, be convenient to dissipation of heat and go out the area of dissipation that has also increased simultaneously radiating fin 2, at upper tabs 21, lower tabs 22, the corresponding buckle 211 that is provided with in the outer end of outer flap 23 is at upper tabs 21, lower tabs 22, the inner end of outer flap 23 is provided with the button hole 212 that the buckle 211 of adjacent radiating fin 2 can snap in.When connecting, buckle 211 on the rear fin in two adjacent radiating fins 2 snaps on the previous fin on the button hole 212, radiating fin 2 after the connection forms the cylinder of a hollow, described heat pipe 1 places cylinder, mode by scolding tin is radiating fin 2 and heat pipe 1 seamless link again, thereby solved the large problem of contact-making surface thermal resistance.

Described lower tabs 22 is trapezoidal shape, and the length of trapezoidal upper base 221 is less than trapezoidal 222 the length of going to the bottom.Because the length of trapezoidal upper base 221 is less than trapezoidal 222 the length of going to the bottom, the spacing when adjacent radiating fin 2 is connected increases from the inside to the outside.

But be equipped with increasing heat radiation area and prevent from hindering the flanging 24 of hand in the inner side edge 44 of radiating fin 2 and outer side edges 42.

Described lower tabs 22 outer ends and lower side 43 arc-shaped transition.Arc-shaped transition is so that the heat-dissipating space of the lower end of radiating fin 2 increases, and heat dispersion is better.

Be provided with a plurality of convection holes 25 at described radiating fin 2.Convection holes 25 can increase the flowability of air, improves radiating efficiency.

As shown in Figure 7, be the application of the utility model on bulkhead lamp capable, the utility model is simple in structure, and is applied widely, also can be applicable to the place that floodlight tube, Projecting Lamp, street lamp etc. need the high-powered LED lamp illumination.
