Description

The LED fluorescent lamp

Technical field

The utility model relates to a kind of LED fluorescent lamp, belongs to the LED lighting technical field.

Background technology

In the semiconductor lighting apparatus field, the LED fluorescent lamp has the luminous efficiency height, long service life, and the advantage of energy savings, therefore, the LED fluorescent lamp has obtained application more and more widely as a kind of novel illumination light fixture.At present, the LED fluorescent lamp on the market probably is divided into two kinds, and a kind of is the LED fluorescent lamp of external controller; A kind of be built-in controller from ballast LED fluorescent lamp.But, more than two kinds of LED fluorescent lamps have following shortcoming: one, the lamp luminescence face uniformity is relatively poor, has bigger light and shade difference, influences the comfort level of human eye vision; Two, because the limitation of LED module, radiator and other component structurals; Cause the heat-conductive characteristic between LED module and the radiator relatively poor, each parts assembling more complicated is difficult for installation or removal simultaneously; And the radiating effect of light fixture is poor, and service life is shorter.

The utility model content

The purpose of the utility model is for a kind of LED fluorescent lamp is provided, and this fluorescent lamp makes the luminous more even of fluorescent lamp through optimizing the distance of LED between the array way on the circuit board and adjustment LED module and diffusion shell; Because the heat dissipating housing of this fluorescent lamp has adopted high printing opacity high-quality acrylic or high-quality PC made, after frosted or cloudy surface processing are done in the surface, have good translucent effect and diffuse effect, like this, irradiate light can be more even; Because this fluorescent lamp adopted diffusion shell horizontal bar pressing structure, make and fit closelyr between LED module and the radiator, so not only be convenient to installation or removal, also can improve the radiating effect of light fixture, prolong the service life of light fixture.

In order to achieve the above object, the utility model is realized through following technological means.

A kind of LED fluorescent lamp, it includes diffusion shell, end cap, radiator, driving power, LED module part, it is characterized in that: in radiator, be provided with cavity, driving power places in the cavity, and the two ends of driving power are respectively arranged with the OT coil; Be respectively arranged with two grooves and two first fixing holes at the two ends of radiator, be provided with heat-conducting medium, be provided with the LED module on heat-conducting medium top on the top of radiator; Be connected through lead between driving power and the LED module; Be provided with diffusion shell on LED module top; Be respectively arranged with two horizontal bar pressing structures and two convexities at the two ends of diffusion shell; Two ends at radiator are respectively arranged with end cap, and end cap is provided with metal ferrule, through hole, second fixing hole; The OT coil is through being bolted on second fixing hole, is connected through screw between first fixing hole and the through hole, is connected through the OT coil between driving power and the end cap; The OT coil is connected with the metal ferrule of end cap rear end.

The outer surface of described driving power is coated with insulating materials, and diffusion shell adopts high printing opacity high-quality acrylic or high-quality PC material to process, and end cap adopts high-quality acrylic or high-quality PC material to process.

The utility model mainly has following beneficial effect:

1, this fluorescent lamp makes the luminous more even of fluorescent lamp through optimizing the distance of LED between the array way on the circuit board and adjustment LED module and diffusion shell;

2, because the heat dissipating housing of this fluorescent lamp has adopted high printing opacity high-quality acrylic or high-quality PC made, after frosted or cloudy surface processing are done in the surface, have good translucent effect and diffuse effect, like this, irradiate light can be more even;

3, because this fluorescent lamp has adopted diffusion shell horizontal bar pressing structure, make between LED module and the radiator and to fit closelyr, so not only be convenient to installation or removal, also can improve the radiating effect of light fixture, prolong the service life of light fixture.
