Description

A kind of LED fluorescent lamp

Technical field

The utility model relates to the LED field, concretely, is meant the semicircle luminous great power LED of a kind of employing as light source, long life and high efficiency high-power LED daylight lamp.

Background technology

Existing LED fluorescent lamp substantially all is the low-power LED array way that adopts many plug-in units or paster, and horizontal direction is arranged in fluorescent lamp inside, and it is projeced into plane of illumination after sending light transmission fluorescent lamp lampshade.

The LED fluorescent lamp of said structure because it has adopted a considerable amount of low-power LED arrays, very easily occurs causing whole the dead lamp phenomenon of fluorescent lamp behind the dead lamp of partial L ED; And existing LED fluorescent lamp is dazzled optical phenomenon in order to solve, and usually lampshade is made translucently or vaporific, and this way can reduce the light utilization ratio greatly.

The utility model content

The purpose of this utility model is to provide a kind of LED fluorescent lamp, and it can overcome existing defective, promotes the performance and the service life of LED fluorescent lamp, in addition, improves utilization ratio.

In order to solve the problem that prior art exists, the technical scheme that the utility model adopted is:

A kind of high-power LED daylight lamp, it comprises fluorescent lamp leaded light lampshade, driving power, light emitting diode and end cap, and it also includes and draws the aluminium shell, and described aluminium shell and the described fluorescent lamp leaded light lampshade of drawing combined; Described driving power is arranged on described drawing in the aluminium shell; Described light emitting diode is arranged on end cap and draws between the aluminium shell; End cap links to each other by electric wire with driving power.

Preferably, above-mentioned light emitting diode is configured as semicircle.

Preferably, above-mentioned fluorescent lamp leaded light lampshade is configured as semicircle, and the described aluminium shell that draws is configured as semicircle, and described fluorescent lamp leaded light lampshade and the described aluminium shell that draws combine, and form a complete circular fluorescent lamp lamp body.

Preferably, the above-mentioned plane of drawing the aluminium shell is provided with reflector layer.

Preferably, be provided with the heat-conducting cream layer between the heat radiation plane of above-mentioned light emitting diode and described two end sections of drawing the aluminium shell.

Preferably, above-mentioned driving power is arranged on described inner hollow position, two ends of drawing the aluminium shell.

After adopting said structure, during use, the utility model large-power light-emitting diodes is linked into driving power with civil power by the civil power wiring through the terminal of two ends end cap, driving power output meets the required parameter value of semicircle luminous heavy-duty diode work, by driving the corresponding both positive and negative polarity that output line is connected to semicircle luminous heavy-duty diode, make semicircle luminous heavy-duty diode light luminous.Because this novel semicircle luminous large-power light-emitting diodes that uniqueness is set at the fluorescent lamp two ends, improves the easily dead lamp problem of low power LED array way of One's name is legion as light source, promotes LED fluorescent lamp performance and service life; In addition, adopt and draw the aluminium shell reflector layer to be set, directly adopt the Transparent lamp shade of high-transmittance, reduce light loss, improve the light utilization ratio as the radiator plane in semicircle.
