Abstract
The utility model discloses a heat radiation structure of a lamp. The heat radiation structure of the lamp comprises a lamp shell (1), wherein an LED light source module (2) is arranged in the lamp shell (1), and a plurality of cooing fins (3) are arranged below the LED light source module (2). The heat radiation structure of the lamp is characterized in that a radiator (4) is arranged below the cooling fins (3), the radiator (4) comprises a base plate (5), a plurality of cooling ribs (6) which are combined with the cooling fins (4) in a crossing mode are arranged on the base plate (5), and the lateral portions of the cooling ribs (6) are attached to the lamp shell (1). The heat radiation structure of the lamp has the advantages that heat on the cooling fins can be effectively transmitted out of the lamp shell, the cooling effect is greatly improved, invalidation, caused by the over-high temperature, of the LED light source module is avoided, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of radiator structure of LED light fixture.
Background technology
LED, life-span long superior function energy-efficient, safe and reliable with it in recent years obtains social approval, and by increasingly extensive application.Along with the development of LED, the appearance of the great power LED of super brightness, transmitting white, make the application of LED expand home lighting, town and country lighting engineering and road lighting to.Although the luminous efficiency of LED is very high, be that general high voltage is received 2 times to 2.5 times of lamp, still have in actual use a certain proportion of electric energy energy transform into heat energy.And high-power LED lamp is actually the application of many single great power LED dense arrangement combinations, so in use can produce the heat of a large amount of accumulations.The cooling measure of existing LED light fixture is that LED light emitting module and radiator are directly fitted, yet because the LED fitting structure is numerous, there is the pyrotoxin of the LED light fixture of quite a few directly to fit with radiator, if this class LED light fixture is not taked the measure of heat radiation, the heat of building up will cause the excess Temperature of LED chip, when the temperature of chip surpasses certain value, will cause the deterioration of LED duty, thereby cause the reduction of luminous efficiency and the shortening in life-span.Therefore, solving the problem of distributing of LED light fixture heat, is to improve the life-span of LED light fixture and the key of luminous efficiency.
The utility model content
The purpose of this utility model is, a kind of radiator structure of light fixture is provided.The utility model has improved radiating effect of the present utility model widely, in the situation that pyrotoxin and radiator can not directly be fitted, radiator has avoided the LED light source module to lose efficacy because of excess Temperature, has extended the life-span of product.
The technical solution of the utility model: the radiator structure of light fixture, comprise lamp casing, be provided with a LED light source module in lamp casing, the bottom of LED light source module has the multi-disc fin, the below of described fin is provided with a radiator, radiator comprises a base plate, and base plate top is provided with multi-disc and fin and intersects chimeric radiating ribs; The sidepiece of described radiating ribs and lamp casing laminating.
In the radiator structure of aforesaid light fixture, the below of described lamp casing offers the external cooling muscle.
In the radiator structure of aforesaid light fixture, the below of described lamp casing offers radiating groove, and the external cooling muscle is arranged on the internal groove side wall of radiating groove.
In the radiator structure of aforesaid light fixture, the groove of described radiating groove top has a heat-exchange surface, the base plate of described radiator and heat-exchange surface laminating.
Compared with prior art, the utility model is provided with a radiator in lamp casing, and the fin of the radiating ribs of radiator and LED light source module intersects chimeric, and the sidepiece of radiator and lamp casing laminating; Therefore the heat that the LED light source module is sent is passed on radiator by radiation theory, conduct to lamp casing through radiator again, by lamp casing, heat is conducted to outside, improved widely radiating effect of the present utility model, avoid the LED light source module to lose efficacy because of excess Temperature, extended the life-span of product.As preferably, offer the external cooling muscle below described lamp casing, make lamp casing there is better heat loss effect.Further preferably, described external cooling muscle is arranged in radiating groove, touching external cooling muscle while having avoided artificial contact lamp casing and injuring.Further, the groove of radiating groove top has a heat-exchange surface, the base plate of radiator and heat-exchange surface laminating, and the heat that makes radiator be drawn to is the external cooling muscle in heat-exchange surface conducts to radiating groove better, improves radiating effect.
