Abstract
The utility model discloses an LED lamp with a heat dissipation device. The LED lamp comprises a body and a panel that is arranged in front of the body; an LED integrated circuit plate and a lens are arranged in the body; and the heat dissipation device is arranged at the rear part of the LED integrated circuit plate. The LED lamp is characterized in that a metal spring washer is clamped between the heat dissipation device and the body. The LED lamp is provided with the metal spring washer, thereby solving the problem that the heat dissipation device and the LED integrated circuit plate in the original LED lamp are connected with each other unstably, preventing the loosening of the connection of the heat dissipation device and the circuit plate caused by shocking or environmental influence in the process of long-time use and also solving the problem of chip damage due to insufficient heat dissipation, so that the service life of the LED lamp is greatly prolonged.
Description
Technical field
The utility model relates to a kind of lighting apparatus, particularly a kind of LED lamp that has heat abstractor.
Background technology
The LED lamp is as a kind of novel energy-saving environment-friendly lighting apparatus, its integrated degree improves day by day, and volume is more and more littler, and brightness is also more and more higher, thereby the heat that brings also can be increasing, along with the increase of LED power, the heat of generation is more, if do not resolve heat dissipation problem, a large amount of heats all can concentrate on the chip, aggravated the aging of chip and circuit, shortened the life-span of LED lamp core work part, even can burn chip.
The heat that how the high-powered LED lamp chip is produced leaves fast, makes LED lamp operate as normal in the temperature of regulation, so heat dissipation problem has become the major obstacle that its performance of restriction improves.Many at present employings are installed to radiator on the surface-mounted integrated circuit dispels the heat, yet because existing its radiator of LED lamp and circuit board are often owing to being connected defective tightness, in the perhaps long-term use, because causing being connected between radiator and the circuit board, the vibrations or the influence of environment become flexible, make that heat radiation damages chip owing to can not get effectively, thereby had a strong impact on the service life of LED lamp.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple and stable structure, connects the heat abstractor of more firm LED lamp.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED lamp that has heat abstractor, panel before comprising body and being installed in body, be provided with LED surface-mounted integrated circuit and lens in the described body, described LED integrated circuit postlaminar part is equipped with radiator, is arranged with the metal spring pad between described radiator and the body.
The described LED lamp that has heat abstractor also comprises and is fixed on this external support, and spring, described spring one end is fixed on the support, and its other end is fixedly attached on the LED surface-mounted integrated circuit, be arranged with the Aluminum Hollow post on the described spring, described Aluminum Hollow post sidewall has tapped through hole.
The beneficial effects of the utility model are: owing to before the LED lamp body panel is set, be provided with LED surface-mounted integrated circuit and lens in the body, LED integrated circuit postlaminar part is equipped with radiator, card is established the metal spring pad between radiator and body then, by being set, the heat abstractor that this metal spring pad solved in the LED lamp in the past is connected problem of unstable with the LED surface-mounted integrated circuit, prevented in the long-term use, because causing being connected between radiator and the circuit board, the vibrations or the influence of environment become flexible, make that heat radiation damages chip owing to can not get effectively, thereby prolonged the service life of LED lamp greatly.
Be fixed on this external support, and spring, described spring one end is fixed on the support, its other end is fixedly attached on the LED surface-mounted integrated circuit, is arranged with the Aluminum Hollow post on the spring, and described Aluminum Hollow post sidewall has tapped through hole, utilize then on the Aluminum Hollow post and screw screw by tightening up spring, make the LED surface-mounted integrated circuit be pressed on the radiator, structure is simple more and stable, and good seismic performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is an explosive view of the present utility model;
Fig. 3 is a stereochemical structure cutaway view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of LED lamp that has heat abstractor, panel 2 before comprising body 1 and being installed in body 1, be provided with LED surface-mounted integrated circuit 11 and lens 12 in the described body, described LED surface-mounted integrated circuit 11 rear portions are equipped with radiator 13, are arranged with metal spring pad 3 between described radiator 13 and the body 1.By being set, the heat abstractor that this metal spring pad 3 solved in the LED lamp in the past is connected problem of unstable with LED surface-mounted integrated circuit 11, prevented in the long-term use, because causing being connected between radiator 13 and the LED surface-mounted integrated circuit 11, the vibrations or the influence of environment become flexible, make that heat radiation damages chip owing to can not get effectively, thereby prolonged the service life of LED lamp greatly.
The heat abstractor of described LED lamp also comprises the support 4 that is fixed on outside the body 1, and spring 5, described spring 5 one ends are fixed on the support 4, and its other end is fixedly attached on the LED surface-mounted integrated circuit 11, be arranged with Aluminum Hollow post 6 on the described spring 5, described Aluminum Hollow post 6 sidewalls have tapped through hole 61.Utilize then on Aluminum Hollow post 6 and screw screw by tightening up spring 5, make LED surface-mounted integrated circuit 11 be pressed on the radiator 13, structure is simple more and stable, and good seismic performance.
Described radiator is provided with the groove that holds Aluminum Hollow post 6 at its end middle part near LED surface-mounted integrated circuit 11.Such design feature, after tightening up spring, Aluminum Hollow post 6 makes Aluminum Hollow post 6 and spring 5 become an integral body by trip bolt, block Aluminum Hollow post 6 by this groove then, when LED surface-mounted integrated circuit 11 was pressed on the radiator 13, this groove played the effect of support fixation to Aluminum Hollow post 6; Simultaneously, such structure is also dwindled the volume of LED lamp, and structure is stable and compact more.
