The utility model provides a radiating lamp comprising a lamp socket, a luminous unit and a plurality of radiating fins, wherein the luminous unit is arranged at the lamp socket; and the plurality of radiating fins are connected with the luminous unit and formed with at least one perforation, thus leading airflow to be capable of directly flowing through the two-phase opposite sides of the radiating fins, bringing away the heat generated when the luminous unit works, and further achieving the best radiating effect.

Description

The heat radiation light fixture

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of heat radiation light fixture with fin.

Background technology

Because environmental consciousness strengthens now, the luminescence component in the light-emitting device of using always in many lives (for example: light fixture, traffic lights etc.) replaces to the light emitting diode that volume is little and power consumption is lower (LED) all gradually.

With street lamp, its light emitting diode that can be provided with at least one usually increases its illuminance.And in order to increase the service life of light emitting diode, street lamp also can connect most radiating fins in a side of the non-illumination of light emitting diode, disclose as Taiwan patent M358258 patent case, derive in order to the used heat that light emitting diode is produced when throwing light on operation.Yet along with the luminous intensity of the quantity of light emitting diode in the light-emitting device and light emitting diode is cumulative every day, the radiating mode that is disclosed as above-mentioned patent case can't more effectively dispel the heat.

Summary of the invention

The purpose of this utility model is to provide a kind of heat radiation light fixture that can improve radiating efficiency.

The utility model heat radiation light fixture comprises: a lamp socket, a luminescence unit and most fin.Luminescence unit is arranged on lamp socket, and described fin is connected with luminescence unit, and is formed with at least one perforation on each fin, makes that air-flow can be directly mobile at two opposition sides of each fin, take away with the heat energy that luminescence unit is produced when working, reach best radiating effect.

In addition, the upright projection of the perforation on each fin is overlapped to small part.Preferably, the perforation on all fin is centered close to same straight line.

Useful effect of the present utility model is: the special design by radiator can make thermal louver have more better heat radiating effect.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Consult Fig. 1 and Fig. 2, preferred embodiment for the utility model heat radiation light fixture 100, this heat radiation light fixture 100 comprises a lamp socket 1, a luminescence unit 2 and a radiator 3, wherein pass through the design of radiator 3, the heat energy that can be more quickly luminescence unit 2 be produced when luminous looses and removes, to reach the effect of best heat radiation.

Lamp socket 1 has a pedestal portion 11 and a spiro union portion 12.In the present embodiment, pedestal portion 11 moulded be bowl-shape and wherein a side be formed with an opening 110; Spiro union portion 12 is positioned at the side of pedestal portion 11 in contrast to opening 110, and its suitable screw lock is in being arranged on power socket on the wall (figure does not show), to receive luminescence unit 2 required electric power when the work.

Luminescence unit 2 has a circuit board (PCB) 22 that is electrically connected with lamp socket 1, and most the luminescence components 23 that are arranged on the circuit board 22, and wherein the luminescence component 23 of present embodiment is light emitting diode (LED), but not as limit.In addition, heat radiation light fixture 100 also comprises the lampshade 4 that a cover overlays on luminescence unit 2, and lampshade 4 interconnects with lamp socket 1, and made by the light transmission material, and the light source that makes luminescence component 23 be produced when work can be dissipated into the outside via lampshade 4.

Cooperate and consult Fig. 3, radiator 3 engages with luminescence unit 2, and wherein has a junction 31 and most and connecting portion 31 vertically disposed fin 32.In the present embodiment, connecting portion 31 is all heat-conducting equally with these fin 32, and connecting portion 31 is one-body molded with these fin 32, can certainly be to be formed by connecting after making respectively again, does not exceed with present embodiment.Moreover connecting portion 31 can be fixed on the circuit board 22 by modes such as screw lock or engagings in contrast to the opposite side of fin 32, makes fin 32 heat that circuit board 22 and luminescence component 23 are produced when the work can be exported to the outside.And these fin 32 have a body 321 and at least one perforation 322 respectively.

Each fin 32 is arranged on the lamp socket 1 abreast, so that air-flow can be along the length direction of the body 321 that is parallel to each fin 32, just flow in the space between two adjacent fin 32, and the heat energy that is produced during with luminescence unit 2 work is taken away.

In addition, the vertical view that cooperates the heat radiation light fixture 100 of consulting Fig. 4.In the present embodiment, all can be formed with 6 perforation 322 on each fin 32, its quantity is not limited, it can be directly passes through at two opposition sides of the body 321 of each fin 32 in order to length direction airflow flowing along vertical (or near vertical) in the body 321 of each fin 32 to be provided, more to increase the radiating effect of radiator 3.

Preferably, the upright projection of the perforation 322 on each fin 32 can be overlapped at least in part, makes air-flow more can be successfully pass through at two opposition sides of the body 321 of fin 32, to reach best radiating effect.And best mode promptly be on all fin 32 perforation 322 be centered close to same straight line.

For the manufacturing process of simple and easy radiator 3 and the cost in the reduction making, the radiator 3 of present embodiment be with fin 32 and connecting portion 31 one-body molded after, utilize drilling tool all fin 32 to be carried out bore operation again with length direction perpendicular to the body 321 of each fin 32, the size of the perforation 322 on promptly all fin 32 can be identical and its center also can be positioned at same straight line.Certainly, each fin 32 also can utilize the drilling tool in different apertures to get out the perforation 322 in different apertures respectively, can also just form perforation 322 on fin 32 when fin 32 is made, does not so then need additionally to carry out follow-up bore operation.

Special one carry be, on these fin 32, form perforation 322 mainly provide to air-flow directly two opposition sides of these fin 32 by and usefulness that heat energy is taken away, therefore, these fin 32 in use will be not can not bored a hole at it and be penetrated any heat-conductive assembly in 322, for example: heat pipe, with the radiating effect of the best of reaching radiator 3.

In sum, the utility model heat radiation light fixture 100 is by forming at least one perforation 322 on its fin 32, make length direction airflow flowing to bore a hole 322 and heat energy that circuit board 22 and luminescence component 23 are produced during in work is taken away, with the radiating effect of the best of reaching radiator 3 by each along vertical (or near vertical) in the body 321 of each fin 32.
