Abstract
The invention discloses an LED lamp tube comprising an upper cover, an LED base plate, a heat radiator, a power supply and a lamp cap; the LED base plate is installed between the upper cover and the heat radiator; the lamp cap is installed at two ends of the LED lamp tube; the LED base plate clings to the heat radiator and the LED base and the heat radiator are installed together; the cross section of the upper cover is a segment of more than 180 DEG; the cross section of the heat radiator is a segment of less than 180 DEG; and the cross sections of the upper cover and the heat radiator form an entire circle. In the LED lamp tube provided by the invention, the LED base plate is tightly connected with the heat radiator, and no air blockage exists between the LED base plate and the heat radiator, therefore, the heat radiation efficiency is greatly increased; the power supply is arranged at two ends of the LED lamp tube, thus, the heat of the power supply is prevented from entering the LED lamp tube, and the heat radiation load of the heat radiator is lowered, and the running reliability of the LED lamp tube is improved; and the transmitting angle of the upper cover exceeds 180 DEG, therefore, a better lighting effect is obtained.
Description
Technical field
The present invention relates to lighting technical field, particularly relate to a kind of LED fluorescent tube.
Background technology
The LED lamp has become trend in the lighting technical field at present.But for most families, use remain fluorescent tube, so with the specifications design of LED lamp for being necessary on the lamp socket that can be installed in the conventional fluorescent lamps pipe, the waste of having avoided extensive more lamp changing base to produce.The problem that present LED fluorescent tube exists is the inside that LED places fluorescent tube, is air between LED and fluorescent tube shell, and power supply designs in fluorescent tube inside, and radiating effect is poor.In addition, the LED base plate that LED is installed is positioned at the center of LED fluorescent tube, and this light that makes LED send can only send by 180 ° diffuser, and illumination zone is too small.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art and a kind of LED fluorescent tube is provided, it has extraordinary heat-sinking capability, and translucent effect is good.
Purpose of the present invention realizes by following technical measures.
A kind of LED fluorescent tube, comprise loam cake, LED base plate, radiator, power supply and lamp holder, described LED base plate is installed between described loam cake and the radiator, described lamp holder is installed in the two ends of described LED fluorescent tube, described LED base plate and described radiator are adjacent to and are installed together, the cross section of described loam cake is scarce greater than 180 ° circle, and the cross section of described radiator is scarce less than 180 ° circle, and the cross section of described loam cake and radiator is formed complete circle.
Described power supply is installed in the lamp holder at two ends of described LED fluorescent tube.
Described lamp holder offers the heat radiation seam.
Described radiator comprises substrate and is positioned at the last card article of the projection at substrate two ends that described LED base plate is adjacent to and is installed in two described going up between the card article.
Described radiator also is provided with a plurality of fin that are parallel to each other perpendicular to described substrate, goes up two opposite following card articles of card article protrusion direction with described, and the end card article that is positioned on outermost two fin and extends perpendicular to described fin; Described loam cake comprises the printing opacity arc, be positioned at described printing opacity arc card article terminal and that stretch to the printing opacity arc, and perpendicular to card article in described and the interior hook that in described printing opacity arc, stretches; Described card article down is stuck in the space that forms between described interior hook and the interior card article, and described interior hook and interior card article are stuck in the space that forms between described card article down and the end card article.
The surface of described fin is provided with continuous ripple.
Be provided with light barrier between described power supply and the described LED base plate.
Described loam cake is that the PC that has diffusant makes.
LED fluorescent tube of the present invention, LED base plate and radiator close proximity do not have air to hinder between LED base plate and radiator, so radiating efficiency are greatly improved; And power supply is placed on the two ends of LED fluorescent tube, and avoided the heat of power supply to enter LED fluorescent tube inside, reduced the heat radiation burden of radiator, improved the operational reliability of LED fluorescent tube; The printing opacity angle of loam cake has surpassed 180 °, has better illuminating effect.
