Abstract
The invention discloses an LED (Light Emitting Diode) fluorescent tube with a good heat radiation effect and a large light emitting angle, comprising a light-transmitting lampshade, an LED chip, a heat conducting plate, a heat conduction insulated heat radiating element, a power supply and an end cover. The LED fluorescent tube with the good heat radiation effect and the large light emitting angle is characterized in that a hole is formed in the middle of the heat conduction insulated heat radiating element; an aluminum alloy tube with the same shape as the hole is embedded in the middle of the hole; the upper step of the heat conduction insulated heat radiating element is adhered with the heat conducting plate through a heat conducting adhesive agent; the edge of the heat conducting insulated heat radiating element is fixedly connected with the light-transmitting lampshade; two ends of the light-transmitting lampshade are fixedly connected with the end cover; and the LED chip is stuck to the heat conducting plate; heat is diffused on the heat conducting plate, transferred to the step of the heat conduction insulated heat radiating element through the heat conducting adhesive agent, uniformly diffused again through the aluminum alloy tube embedded in the middle of the heat conduction insulated heat radiating element and finally transferred to the outer surface of the heat conduction insulated heat radiating element to realize heat radiation. The LED chip is stuck to the heat conducting plate arranged in the center of the light-transmitting lampshade, and the light emitting angle of the lamp is larger than 180 degrees after being transmitted and reflected, so that the LED fluorescent tube has the good heat radiation effect and the large light emitting angle.
Description
Technical field
The present invention relates to a kind of LED fluorescent tube, particularly the large fluorescent tube of a kind of good heat dissipation lighting angle.
Background technology
LED fluorescent tube fluorescent tube as an alternative, in commercial lighting, office lighting uses popularity, and to daily life, work brings great convenience, and the LED fluorescent tube occurring at present adopts aluminium section bar, PC cover, LED and lamp plate composition.Its structural principle is that the heat that LED distributes is passed through to import lamp plate, then imports aluminium section bar and is dispersed in air.This aluminium section bar is as shell radiating element, and quality weight, conducts electricity, dangerous.Aluminium section bar accounts for fluorescent tube half and above space, and the lighting angle of fluorescent tube is little.
Summary of the invention
The object of the invention is, in order to overcome the shortcoming that existing LED fluorescent tube radiating effect is poor, lighting angle is little, provides the LED fluorescent tube that a kind of good heat dissipation lighting angle is large.
Technical scheme of the present invention is, the LED fluorescent tube that a kind of good heat dissipation lighting angle is large, comprise transparent lamp shade, LED chip, heat-conducting plate, heat conductive insulating radiating piece, power supply and end cap, it is characterized in that, described heat conductive insulating radiating piece middle part is equipped with a hole, in the middle of described hole, inlay an aluminium-alloy pipe identical with this hole shape, described heat conductive insulating radiating piece upper step and heat-conducting plate are bonding with heat conduction bonded adhesives, edge and the transparent lamp shade of described heat conductive insulating radiating piece are affixed, described transparent lamp shade two ends and end cap are affixed, described LED chip is attached on heat-conducting plate, the heat that LED chip is produced spreads on heat-conducting plate, be delivered on heat conductive insulating radiating piece step by heat conduction bonded adhesives again, again heat is evenly spread apart by the aluminium-alloy pipe being embedded in the middle of heat conductive insulating radiating piece hole, finally be delivered to the heat radiation of heat conductive insulating radiating piece outer surface, described power supply is placed in the end cap at transparent lamp shade two ends.
Because described LED chip is attached on heat-conducting plate, the heat that LED chip is produced spreads on heat-conducting plate, be delivered on heat conductive insulating radiating piece step by heat conduction bonded adhesives again, again heat is evenly spread apart by the aluminium-alloy pipe being embedded in the middle of heat conductive insulating radiating piece hole, be finally delivered to the heat radiation of heat conductive insulating radiating piece outer surface.Described LED chip is attached on the heat-conducting plate of the center of diffuser, LED chip sends the light of 120 degree angles, is mapped to the transmission of transparent lamp shade inner surface part light and goes out, and a part of light reflects, go out from the transmission of transparent lamp shade bottom again, the lighting angle of whole light is greater than 180 degree.Therefore LED fluorescent tube good heat dissipation effect of the present invention and lighting angle are large.Because LED fluorescent tube of the present invention is mainly made up of plastic material, with a small amount of aluminum alloy materials, for heat conduction, whole fluorescent tube quality is light again.
