Abstract
The utility model provides a heat radiating section material of an LED (Light Emitting Diode) lamp. The heat radiating section material comprises a heat radiating body, wherein the heat radiating body is provided with a substrate mounting surface. The heat radiating section material is characterized in that radiating fins which are in serrated arrangement are arranged at the other side, corresponding to the substrate mounting surface, of the heat radiating body, a circular concave mounting position is formed at one end of the heat radiating body, and a circular concave mounting position is formed at the other end of the heat radiating body. Due to the adoption of the structure, the heat radiating body is provided with the radiating fins which are in serrated arrangement, so that the heat radiating area is increased greatly; the size of each radiating fin meets the requirements, so that the heat radiating effect is enhanced, meanwhile, the difficulty of extruding production is lowered, the weight of the product is reduced, and the production cost is reduced; the heat radiating section material is formed through aluminum casting, so that the heat conductivity is improved, the heat radiating area is increased, heat emitted during the work of the LED lamp can be transferred out quickly, the temperature of junction temperature points can be lowered, and the service life of the LED lamp is prolonged greatly; the two ends of the heat radiating section material adopt circular concave and convex mounting positions, so that the use requirements of different places can be met, and the diversity is realized.
Description
Technical field
The utility model relates to LED lamp lighting technical field, is specifically related to the aluminium section bar that a kind of LED light fixture heat radiation is used.
Background technology
Due to LED light fixture have power consumption less, volume is little, response is fast, antidetonation, anti-low temperature, pollute the advantages such as little, in actual life with industry in a large amount of universal uses all.In use, LED lamp is used, and all can transform a kind of large heat energy, and this heat energy is that light fixture is produced to huge side effect, if can not efficiently radiates heat, can make LED internal temperature raise, temperature is higher, and the luminous efficiency of LED is lower, and the life-span of LED is shorter, in serious situation, can cause LED wafer to lose efficacy at once, so heat radiation is still the huge obstacle of great power LED application.
The use of LED lamp spreads all over extensively, comprises office building office, market, family expenses and other high-grade place.
Present LED lamp, the common method of its heat radiation is all that the heat of light source conducts to fin and lamp housing by illuminator, then by fin and lamp housing, heat is exhaled.In actual use, find, the heat radiation of LED light fixture, simple fin can not reach effective radiating effect, and some design can reach efficiently radiates heat, but design is complicated, and forming requirements is high, and production efficiency is not high and section bar weight ratio is larger.Some complicated radiator designs need to be considered the consideration of design for aesthetic or expense aspect simultaneously, and in production process, its extruding production difficulty is larger simultaneously, and following process flow process and cost compare are high.
Summary of the invention
For addressing the above problem, effectively improve the heat radiation of LED light fixture, improve the service life of LED light fixture, reduction manufactures a finished product, and the utility model provides a kind of LED lamp heat sink section bar, comprises radiator, described radiator is provided with substrate installed surface, it is characterized in that: described radiator counterpart substrate installed surface opposite side is provided with the fin that indentation arranges, and described radiator one end is provided with round concave shape installation position, and the other end is provided with round convex shape installation position.
Described fin is the wide 1.7～2.0mm of being in top, and bottom is wide is 3.5～4.0mm.
The length of described fin is 15～15.5mm.
Described radiator and fin are to adopt aluminium integrally formed.
Adopt after said structure, radiator is provided with the fin that zigzag arranges, and has greatly strengthened area of dissipation, and the sizeable requirement setting of its fin strengthens radiating effect, reduces extruding production difficulty simultaneously, alleviates product weight, reduces production costs; Adopt aluminum casting, the lifting of its thermal conductivity and the increasing of area of dissipation, and the heat sending when LED lamp can be worked can promptly shift away, can reduce junction temperature point temperature, improves widely the LED lamp life-span.Two ends adopt respectively the recessed round convex shape of circle installation position, realize different places instructions for use, realize diversity.
The utility model is simple in structure, practical, improves thermal diffusivity, usability and the practicality of product.
Accompanying drawing explanation
Fig. 1 is the utility model texture edge schematic diagram.
In figure, be denoted as:
1 radiator, 11 substrate installed surfaces, 12 fin, 13 round concave shape installation positions, 14 round convex shape installation positions.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not form any restriction of the present utility model.
As shown in Figure 1:
A kind of LED lamp heat sink section bar, comprise radiator 1, described radiator 1 is provided with substrate installed surface 11, it is characterized in that: described radiator 1 counterpart substrate installed surface 11 opposite sides are provided with the fin 12 that indentation arranges, described radiator 1 one end is provided with round concave shape installation position 13, and the other end is provided with 14， two ends, round convex shape installation position and adopts respectively the recessed round convex shape of circle installation position, realize different places instructions for use, realize diversity.
Described fin 12 is the wide 1.7～2.0mm of being in top, and bottom is wide is 3.5～4.0mm.
Circle is arranged on the described fin that is positioned at two ends 12 tops, while realize installing to the protection of other parts and strengthen ornamental.
The length of described fin 12 is 15～15.5mm.
Described radiator 1 and fin 12 are to adopt aluminium integrally formed.
Adopt after said structure, radiator is provided with the fin that zigzag arranges, and has greatly strengthened area of dissipation, and the sizeable requirement setting of its fin strengthens radiating effect, reduces extruding production difficulty simultaneously, alleviates product weight, reduces production costs; Adopt aluminum casting, the lifting of its thermal conductivity and the increasing of area of dissipation, and the heat sending when LED lamp can be worked can promptly shift away, can reduce junction temperature point temperature, improves widely the LED lamp life-span.Two ends adopt respectively the recessed round convex shape of circle installation position, realize different places instructions for use, realize diversity.
The utility model is simple in structure, practical, improves thermal diffusivity, usability and the practicality of product.
