Abstract

An LED track lamp comprises a power box, an LED driver, a support rod, a lamp tube, a lamp holder, a transparent plate, a reflection cup, a light source support and an LED light source. The LED track lamp is characterized in that even strip grooves are formed in the inner wall of the lamp tube, the strip grooves in the front of the lamp tube are provided with screw teeth, the screw teeth are matched with threads of the lamp holder, the bottom of the lamp tube is in the shape of an annular net, the bottom of the lamp tube is provided with a rear cover plate, a rotating support is arranged between the rear cover plate and the bottom of the lamp tube, the two ends of a power box cover plate of the power box are respectively provided with a movable fastener, the bottom of the power box is provided with a cylindrical connector, the cylindrical connector of the power box is connected with the support rod through a connector, the lamp tube is a lamp body of the track lamp, the strip grooves are formed in the inner wall of the lamp tube, and the lamp holder and the rear cover plate are both embedded into the lamp tube. Thus, ventilation can be achieved on the front portion of the lamp tube and the rear portion of the lamp tube, when the track lamp runs, pressure difference of cold air and hot air can be generated, cross-ventilation is formed for heat dissipation, and therefore the service life of the track lamp is prolonged.

Description

A kind of LED track lamp

Technical field

The utility model relates to LED track lamp technical field, relates in particular to that a kind of radiating effect is better, processing is simpler, LED track lamp is easily installed.

Background technology

Track lamp is at the show window of business, exhibition position, sales counter, the aspects such as signboard are very extensive, its structure comprises it being lamp body substantially, arm assembly, guide rail box and be arranged on power drives of guide rail box inside etc., and the major part that wherein lamp body is track lamp, now on market in circulation more common lamp body be by LED lamp is tight wrap in lamp body shell within, some lamp body shells are pure cylinder or cups, some lamp body shells are that periphery is strip, with this, LED lamp is dispelled the heat, as the LED rail projecting lamp of the patent No. 201220633475.0, the track lamp of a kind of improvement of patent No. 201220686208.X, these technology have all obtained certain effect to heat radiation, but, in practice, heat radiation does not obtain conspicuousness effect, temperature in lamp body, only to contact to lower the temperature with extraneous air by lamp body shell, cooling not exclusively, naturally affect the life-span of track lamp.

Utility model content

For solving the deficiency of background technology, the utility model provides a kind of omnibearing heat dissipation design, to improve the radiating effect of track lamp, reaches thus the longer life-span of track lamp.

For achieving the above object, the utility model adopts following technical scheme: comprise power pack, LED drives, cradling piece, lamp cylinder, lamp holder, transparent panel, reflector, light source bracket, LED light source, described lamp cylinder inwall is provided with uniform bar groove, on the anterior bar groove of lamp cylinder, there is screw thread, lamp cylinder bottom is ring mesh, described lamp cylinder bottom is provided with back shroud, between back shroud and lamp cylinder bottom, be provided with runing rest, respectively there is a movable buckle at the power pack cover plate two ends of described power pack, the bottom of power pack is provided with cylinder joint, described cylinder joint is connected with cradling piece by connector.

Preferably, described cylinder joint bottom is the protuberance as " key " shape.

Preferably, described connector tangent plane shape, as " H ", has anti-rotation screw above, below inner side be screw thread, centre is sky, side is provided with jam nut hole, after connector is connected with cylinder joint, anti-rotation screw " key " shape protuberance edge bottom the cylinder joint.

Preferably, one of described cradling piece is round thread, coincide with the screw thread of connector, and other end is square porose.

Preferably, described runing rest bottom shape is as " U " shape, and " U " internal orifice size is coincide with cradling piece size, and " U " internal orifice has two fixing feet with holes on limit.

Preferably, described back shroud is closed circular not, and the size of close mouth is equally not large with runing rest bottom " U " shape internal orifice.

The beneficial effects of the utility model are: lamp cylinder is the lamp body of track lamp, the inwall of lamp cylinder is bar groove, lamp holder and back shroud are all recessed luminaire cylinders, the cross ventilation of lamp cylinder like this can produce cold and hot air pressure difference when track lamp is worked, and forms cross-ventilation heat radiation, be able to thus the life-span of advancing the track lamp, the key shape of the protrusion bottom of power pack, makes the track lamp cylinder can not rotating 360 degrees, to prevent the excessive rotation of track lamp.
