Abstract

The utility model relates to the field of light emitting diode (LED) illumination, in particular to a high-power LED fluorescent lamp, which comprises a cylindrical lamp tube, wherein end covers for connecting an external power supply are arranged at both ends of the lamp tube, luminous LED luminous bodies are arranged on the end covers, a reflecting layer is coated in the lamp tube, the LED luminous bodies are sheathed and arranged in the reflecting layer direction in the lamp tube, and a driving power supply electrically connected with the LED luminous bodies is sheathed and arranged in the lamp tube. Thereby, light emitted out from the LED luminous bodies can be emitted out through the lamp tube after being refracted by the reflecting layer for many times, the problem of illumination incapability of the lamp or low illumination brightness can not occur, and the reliability of the lamp fitting can be improved.

Description

A kind of high-power LED daylight lamp

[technical field]

The utility model relates to the LED lighting field, specifically refers to a kind of high-power LED daylight lamp.

[background technology]

LED (Lighting Emitting Diode) is a light emitting diode, it is fixedly luminescent device of a kind of semiconductor, it is to utilize the solid semiconductor chip as luminescent material, in semiconductor, emit superfluous energy and cause photo emissions by carrier generation load, directly send the light of white or other colors, the LED lighting utilizes LED as light emitting source exactly.Under the background of current global shortage of energy, energy-conservation LED causes the sight that people pay close attention to.

The LED fluorescent lamp that generally uses in the market, the profile of employing and the basic identical specification of traditional fluorescent lamp pipe, many group LED are installed in fluorescent tube to be constituted as luminous component, shape is single, be not suitable for the application under the multiple environment, this LED fluorescent lamp is because it has adopted a considerable amount of low-power LEDs to be arranged in array, if easily cause whole the dead lamp phenomenon of fluorescent lamp behind the dead lamp of partial L ED, and the lampshade of this LED fluorescent lamp is made translucent, this can reduce the light utilization ratio greatly, and illumination is low.

[utility model content]

The utility model purpose is to solve the LED fluorescent lamp and is prone to dead lamp and the low problem of illumination, and a kind of a kind of high-power LED daylight lamp of simple in structure, dependable performance is provided.

A kind of high-power LED daylight lamp, comprise cylindric fluorescent tube, the two ends of described fluorescent tube are installed on the end cap that connects external power source, wherein end cap is provided with luminous LED illuminator, scribble reflector layer in the fluorescent tube, described LED illuminator is set in the reflector layer direction in the fluorescent tube, is arranged with the driving power that is electrically connected with the LED illuminator in the fluorescent tube.

Preferably, described fluorescent tube is that the Transparent lamp shade and the semicircular aluminium radiator that draws that dispels the heat of arc constitutes by cross section.

Described reflector layer is coated with and is located at the direction of drawing on the aluminium radiator towards lampshade.

The described aluminium radiator that draws is provided with the fin that increases area of dissipation.

Described driving power is set in and draws in the aluminium radiator.

The utility model high-power LED daylight lamp, comprise cylindric fluorescent tube, the two ends of described fluorescent tube are installed on the end cap that connects external power source, wherein end cap is provided with luminous LED illuminator, scribble reflector layer in the fluorescent tube, described LED illuminator is set in the reflector layer direction in the fluorescent tube, is arranged with the driving power that is electrically connected with the LED illuminator in the fluorescent tube.The repeatedly refraction of the light that sends of LED illuminator by reflector layer sees through fluorescent tube and launches like this, the low problem of dead lamp or illumination can not occur, improved the reliability of light fixture.
