Abstract
The utility model relates to the technical field of illumination, and provides an improved LED (Light Emitting Diode) fluorescent lamp which is simple in structure, good in heat dissipation effect, long in service life and great in light emitting angle. The fluorescent lamp comprises a lampshade, a shell, a driver and more than two LED lamp bars, wherein each LED lamp bar comprises a circuit board and an LED lamp arranged on the circuit board. The circuit board is connected with the driver, the lampshade is arranged on the shell, and the shell consists of a heat conducting plate and a heat dissipation base. The cross section of the heat conducting plate is semi-spherical and a plurality of fixed grooves are formed in the arc-shaped face of the heat conducting plate. The LED lamp bars are respectively arranged on the fixed grooves of the heat conducting plate. The heat dissipation base is attached to the lower surface of the heat conducting plate. Heat conducting copper pipes are arranged at the connecting surface between the heat conducting plate and of the heat dissipation base.
Description
Technical field
The utility model relates to lighting technical field, relates in particular to a kind of modified LED fluorescent lamp.
Background technology
Along with current LED fluorescent tube is that LED lamp is welded on pcb board, with heat-conducting glue, be attached on aluminum hull and dispel the heat, utilize driver transformation, voltage stabilizing, current limliting, after energising, LED lamp is luminous, every LED lamp is used power all to have certain scope, as requested power output size and the number of configuration mounted LED lamp.Open market is used public illumination substantially to use fluorescent lamp, along with the use of LED lamp, saves the electricity charge of 55%-65% than original fluorescent lamp.But there is following shortcoming in existing LED lamp: the output light source of LED lamp is 120 degree only, and brightness irregularities, there is stronger light-gathering, use lamp panel and luminescent support can not bring into play catadioptric effect, people must stand in the front of LED lamp just can experience higher brightness, and existing LED fluorescent tube is substantially all to adopt the heat sink being arranged under LED lamp bar to dispel the heat simultaneously, and radiating effect is poor, the heat that LED lamp produces can not dispel the heat timely, has affected the service life of LED fluorescent tube.
Summary of the invention
Therefore,, for above-mentioned problem, the utility model proposes a kind of simple in structure, good heat dissipation effect, long service life, modified LED fluorescent lamp that lighting angle is large.
For solving this technical problem, the utility model is taked following scheme: a kind of modified LED fluorescent lamp, comprise lampshade, housing, driver and two above LED lamp bars, described LED lamp bar comprises circuit board and is located at the LED lamp on circuit board, described circuit board is connected with driver, described lampshade is located on housing, described housing consists of heat-conducting plate and cooling base, the shape of cross section of described heat-conducting plate is hemispherical, the arcwall face of described heat-conducting plate is provided with a plurality of holddown grooves, each described LED lamp bar is laid on the holddown groove of heat-conducting plate respectively, described cooling base is attached at the lower surface of heat-conducting plate, between described heat-conducting plate and cooling base joint face, be provided with heat-conducting copper pipe.
Further, described cooling base is provided with hollow reservoir, and the both sides that are positioned at hollow reservoir on described cooling base are provided with a plurality of air-permeating holes.
Further, described cooling base is positioned at hollow reservoir and is provided with the radiator shutter extending to bottom.
