Description
Technical field
This utility model relates to LED illumination device technical field, especially a kind of radiator structure.
Background technology
The advantages such as volume is little, power consumption is low it is known that LED has, high brightness, length in service life,
Currently suffer from pursuing of user, but, when LED works, itself substantial amounts of heat can be produced, if
Can not dispel the heat in time, the service life of LED will be affected.Existing LED radiator structure, in light fixture size
In the case of less, power is relatively big, it is impossible to ensure the heat dispersion of light fixture.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of heat radiation
Structure.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of radiator structure, it includes heat sink body, drives power supply and light source board, in described heat sink body
Portion is provided with several radiating fins, several described radiating fin matrix arrangement inside heat sink body,
Described heat sink body surrounding is provided with several heat dissipation channels being interconnected with radiating fin, described heat radiation
Main body upper end is provided with connecting plate, and described driving power supply is installed on heat sink body by connecting plate, described
Light source board is installed on heat sink body lower end and is electrically connected with driving power supply.
Preferably, the height of described radiating fin is less than the height of heat sink body outer wall.
Preferably, a side also chain of described connecting plate is connected to top cover, and described top cover para-position is fastened on connection
On plate, the upper end of described top cover is additionally provided with the connectivity port with external connection.
Preferably, described heat sink body is positioned at the right opposite of light source board and is provided with lampshade.
Owing to have employed such scheme, this utility model directly carries out heat by heat sink body and light source board
Conduction；Meanwhile, several radiating fin increasing heat radiation areas are utilized to strengthen radiating effect；Further, utilize
Heat dissipation channel realizes the circulation of inner air and outer air, makes radiating fin directly and air contact, its simple in construction,
Easy to operate, there is the strongest practicality.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of this utility model embodiment；
Fig. 2 is the structural representation of the heat sink body of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can
Implement with the multitude of different ways being defined by the claims and covering.
As shown in Figure 1 to Figure 2, the present embodiment provide a kind of radiator structure, it include heat sink body 1,
Driving power supply 3 and light source board 4, heat sink body 1 is internally provided with several radiating fins 8, and several dissipate
Hot fin 8 matrix arrangement is internal in heat sink body 1, and heat sink body 1 surrounding is provided with several and dissipates
The heat dissipation channel 9 that hot fin 8 is interconnected, heat sink body 1 upper end is provided with connecting plate 2, drives power supply
3 are installed on heat sink body 1 by connecting plate 2, light source board 4 be installed on heat sink body 1 lower end and with drive
Galvanic electricity source 3 is electrically connected with.
The light source board 4 of the present embodiment is the luminous source of light fixture, is also main pyrotoxin.The present embodiment profit
Being directly connected to light source board 4 with heat sink body 1, the heat that light source board 4 is sent directly conducts and heat radiation
In main body 1, heat is then spread in air realization heat radiation, meanwhile, heat sink body 1 by heat sink body 1
(radiating fin 8 can also use other forms to the radiating fin 8 of several rectangular arrangement within Li Yonging
Arrangement) increasing heat radiation area, accelerate rate of heat dispation, and, for further speeding up rate of heat dispation, its
Heat sink body 1 surrounding is additionally provided with several heat dissipation channels 9, its strengthen inside and outside air flowing, allow heat radiation
Fin 8 directly contacts in extraneous air, has been greatly reinforced heat sinking benefit, it is ensured that the reliability of light fixture and
Service life.
Further, for strengthening radiating effect, the height of its radiating fin 8 is less than heat sink body 1 outer wall
Highly, after making assembly, there is a cavity in radiating fin 8 and connecting plate 2, strengthens inner air flowing.
Further, a side also chain of connecting plate 2 is connected to top cover 5, and top cover 5 para-position is fastened on connecting plate 2
On, thus further protection drive power supply 3 without damage, meanwhile, the upper end of top cover 5 be additionally provided with
The connectivity port 6 of external connection, in order to user externally connects.
Further, heat sink body 1 is positioned at the right opposite of light source board 4 and is provided with lampshade 7, utilizes lampshade 7 to add
Big illumination zone protects light source board 4 the most simultaneously.
These are only preferred embodiment of the present utility model, not thereby limit patent model of the present utility model
Enclose, every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion,
Or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in patent of the present utility model
In protection domain.
