Abstract
A heat-radiation device of a light-emitting diode (LED) ceiling lamp and a flashlight comprises a lamp board used for installing an LED lamp, wherein an aluminum alloy heat-radiation device integrated with an outer shell is arranged on the back surface of the lamp board. According to the heat-radiation device, a plurality of fins with transverse and vertical lines are arranged on a heat-radiation outer shell plate, the heat-radiation device is made of aluminum alloy material, a heat-radiation board and the lamp board are bonded through insulation heat-conductive silica gel, and screws penetrate a silica gel board through original reserved holes. The heat-radiation device of the LED ceiling lamp and the flashlight is low in manufacturing cost, capable of effectively radiating heat, prolongs the service life of the LED lamp, increases the luminous flux of LEDs, and is strong in practicability.
Description
Technical field
The utility model relates to lighting device field, specifically relates to the heat abstractor of a kind of LED lamp affixed to the ceiling, torch.
Background technology
The illumination of LED lamp affixed to the ceiling, torch is used, though be popularization energetically, but because its price height and practicality wait to investigate, to such an extent as to very few with the person, because these LED light fixtures can produce heat at work, prolongation along with the working time, getting more and more of heat accumulation, and then cause LED lamp heating back brightness decay, damage and extremely lamp even, though can light 5 to 100,000 hours life-span in theory, in fact just not reach at all.Heating problem is the LED deciding factor in service life, solve heat dissipation problem though present most lamp affixed to the ceiling, torch installed aluminum alloy casing additional, but because effectively do not contact with the aluminium alloy heat-dissipating casing, such radiating effect is unsatisfactory.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and the heat abstractor of a kind of LED lamp affixed to the ceiling, torch is provided, and can make its efficiently radiates heat, increases its luminous flux, increases the service life.
For achieving the above object, the technical solution adopted in the utility model is: the heat abstractor of a kind of LED lamp affixed to the ceiling, torch, it comprises for the lamp plate that the LED lamp is installed, aluminium alloy heat abstractor with the shell one is housed at the back side of lamp plate, and described heat abstractor is at the heat-dissipating casing plate a plurality of fin heat abstractors of lines anyhow to be arranged.
Described heat abstractor adopts aluminum alloy materials to make, and it is bonding to utilize insulating heat-conductive silica gel to carry out between heat sink and the lamp plate, passes silica gel plate by original preformed hole and screws screw.
The beneficial effects of the utility model are: cheap, can efficiently radiates heat, and prolonged the life-span of LED lamp, increased the luminous flux of LED, practical.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the heat abstractor of a kind of LED lamp affixed to the ceiling, torch, it comprises that for the lamp plate 1 that the LED lamp is installed at the back side of lamp plate 1 heat abstractor is installed, described heat abstractor is at heat sink 2 a plurality of fin 3 to be arranged fixedly.
Described heat abstractor adopts aluminum alloy materials to make, and it is bonding to utilize the insulating heat-conductive silica gel plate to carry out between heat sink 2 and the lamp plate 1.
Operating procedure of the present utility model is: (1) sticks the thermally conductive and electrically insulating silicone film to the paster that LED is installed or plug-in unit lamp plate earlier, and plug-in unit pastes one deck more, or the aluminum alloy casing grooving becomes the plane to make it as far as possible.
(2) cable-through hole, fixing hole are holed at silica gel plate by lamp plate.Threading, bonding wire add insulating sleeve.
(3) the contrast of the preformed hole of the aluminum alloy casing that has radiating fin and lamp plate, screw screw.
(4) drive unit of torch is at two of lamp plate, and the torch of profile and electric ballast is similar.The driving of lamp affixed to the ceiling is circular, is installed in the center of lamp plate in the heart, is fixed on separately on the preformed hole of heat radiation shell, with the gap 10MM of lamp plate.
(5) or hang, or install the felt pad pin additional by the hole of reserving and fix, buckle the lampshade of preformed groove position again.
Claims (2)
1. the heat abstractor of a LED lamp affixed to the ceiling, torch, it is characterized in that: it comprises for the lamp plate (1) that the LED lamp is installed, the back side at lamp plate (1) is equipped with heat abstractor, and described heat abstractor is at heat sink (2) a plurality of fin (3) to be arranged fixedly.
2. the heat abstractor of a kind of LED lamp affixed to the ceiling according to claim 1, torch is characterized in that: described heat abstractor adopts aluminum alloy materials to make, and utilizes heat conductive insulating silica gel to carry out using screw means after bonding between heat sink (2) and the lamp plate (1).
