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.
Description of drawings
Fig. 1 is a blast structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Ginseng Fig. 1, shown in 2, embodiment for the utility model high-power LED daylight lamp, it comprises cylindric fluorescent tube 10, the two ends of described fluorescent tube 10 are installed on the end cap 20A that connects external power source respectively, 20B, wherein end cap 20A is provided with luminous LED illuminator 30A, end cap 20B is provided with luminous LED illuminator 30B, cover is respectively equipped with and LED illuminator 30A in the fluorescent tube 10, the driving power 40A that 30B is electrically connected, 40B, described driving power 40A, connect by lead 50 between the 40B, driving power output meets semicircle LED illuminator 30A, the parameter value that 30B work is required, be connected to LED illuminator 30A by driving output line (not label), the corresponding both positive and negative polarity of 30B makes semicircle luminous great power LED 30A, 30B lights luminous.In order to obtain better reliability, end cap 20A, 20B and LED illuminator 30A, 30B are standard packages, after assembly breaks down, can change easily; Described fluorescent tube 10 is that the Transparent lamp shade 11 and the semicircular aluminium radiator 12 that draws that dispels the heat of arc constitutes by cross section, the described aluminium radiator 12 that draws is provided with the fin 121 that increases area of dissipation, described driving power 40A, 40B are set in and draw in the aluminium radiator 12, and LED illuminator 30A, 30B are arranged on end cap 20A, 20B and the semicircle hollow position that draws between the aluminium radiator 12.Wherein end cap 20A, 20B are fixed on the two ends that semicircle is drawn aluminium radiator 12, illuminator 30A, 30B and draw the contact-making surface of aluminium radiator 12 to scribble heat-conducting cream (not label) to be beneficial to good heat radiating.
In order to improve light transmittance, scribble reflector layer 13 in the described fluorescent tube 10, described reflector layer 13 is coated with and is located at the direction of drawing on the aluminium radiator 12 towards lampshade 11, described LED illuminator 30A, 30B are set in the reflector layer direction in the lampshade 11, this reflector layer 13 can outwards reflect away the emitting led illuminator 30A of semicircle, light that 30B sends fully, reverberation sees through Transparent lamp shade 11 and is projected to plane of illumination, can improve illumination.
