Abstract

The utility model discloses a high-power LED (light-emitting diode) down lamp, comprising a drive power supply, a light source electric wire (5), LED lamp beads (2) and a reflecting cup (3). The high-power LED down lamp is characterized by further comprising a radiator (1), wherein the radiator (1) uses a cylindrical structure; radiating fins (6) are surrounded and arrayed on the side circumferential surface of the radiator (1); a central through hole (7) is formed in the centre of the radiator (1); the LED lamp beads (2) and the reflecting cup (3) are installed on the bottom end surface of the radiator (1); and the light source electric wire (5) penetrates in the central through hole (7) and is connected with the LED lamp beads (2) and the drive power supply. The high-power LED down lamp with such a structure can stably work under a higher power due to an independent radiator, and is easy to change and replace due to a form and a structure similar to the form and the structure of a traditional down lamp.

Description

High-power LED tube light

Technical field

The utility model relates to the Down lamp product, relates in particular to adopt the high-power Down lamp of LED as light source.

Background technology

Down lamp is the light fixture that a kind of relative ordinary luminaire has more optically focused property, in room lighting, is widely used, and promptly can be used as general lighting and uses; More can be used as the floor light of building luminous environment and use, traditional Down lamp adopts incandescent lamp, Halogen lamp LED or fluorescent lamp etc. as illuminating source usually, yet; Because incandescent lamp belongs to thermal light source, its power consumption is big, brightness is low, the life-span is short, needs the frequent change light source; Though and Halogen lamp LED and fluorescent lamp can be energy-conservation,, be unfavorable for environmental protection because it contains mercury; Therefore adopt LED (light emitting diode) to obtain increasing use as the Down lamp of light source, but on the one hand, because led light source has strict requirement to operating temperature; On the other hand, because the body characteristics of Down lamp cause the power of the LED Down lamp that is used for alternative traditional Down lamp less.

The utility model content

The purpose of the utility model is to provide a kind of heat that utilizes light fixture self to produce to strengthen the wave LED lamp radiator of spreader surface gas flow.

The goal of the invention of the utility model realizes through following technical scheme: high-power LED tube light, and high-power LED tube light includes driving power, light source electric wire, LED lamp pearl and reflector; Also include radiator, radiator adopts cylindrical structural, and the heat sink side side face is around being placed with radiating fin; Radiator central authorities are formed with center through hole; LED lamp pearl and reflector are installed in the radiator bottom face, and the light source electric wire is set in the center through hole, connect LED lamp pearl and driving power.

Further technical scheme is: the radiator bottom face caves inward, and forms the peviform structure, and the outer shell facies of the shape of tub wall and glow cup is suitable, and LED lamp pearl is installed at the bottom of the basin, and reflector is fitted and is installed on the tub wall.

Further technical scheme is: have lampshade to be sealed on the front end of reflector, and lampshade relative one side bottom reflector is a frosting.

Adopt the great power LED Down lamp of this structure, have individual heat sinks, can smooth working at bigger power, and this great power LED Down lamp has and the akin physique structure of traditional Down lamp, is easy to change and substitute.

Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the utility model protection domain includes but are not limited to accompanying drawing and the disclosed content of embodiment.

Description of drawings

Fig. 1 is the perspective view of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

Shown in Fig. 1, the radiator 1 of this great power LED Down lamp adopts cylindrical structural, and some radiating fin 6 uniform ring are around the lateral circle surface that is arranged on radiator 1; The radiator bottom face caves inward, the flat peviform structure of whole one-tenth, and bottom face central authorities have center through hole 7 to run through radiator 1; Eight great power LED lamp pearls 2 are welded on the aluminium base, and aluminium base fits tightly at the bottom of the basin of radiator depression, and the aluminium base back side is coated with heat conductive silica gel; Fit tightly with radiator; Light source electric wire 5 passes center through hole 7 and is communicated with aluminium base, is installed in the bottom of radiator 1 with the identical show-through reflector 3 of radiator depression position tub wall shape, fits with tub wall; The lampshade 4 that is formed with frosting covers reflector 3, is positioned at Down lamp foremost.
