Abstract
The utility model provides a dimming LED fluorescent lamp, which comprises a lighting tube, connecting lines and a switch, wherein, the lighting tube comprises a transparent outer tube, lamp holders arranged at two ends of the transparent outer tube and lamp bases arranged on the lamp holders, wherein, the lamp bases are connected to the switch through connecting lines, a PCB circuit board is arranged inside the transparent outer tube and is connected with the lamp bases, light emitting diodes are regularly arranged on one surface of the PCB circuit board through a welding method, and the fluorescent lamp further comprises an adjustable potentiometer used for regulating current and voltage. Besides having all the advantages of an LED lamp, the LED fluorescent lamp has the following technical effects: 1. the fluorescent lamp can be dimmed in terms of color and intensity, thereby expanding range of application of the LED lamps; and 2. the fluorescent lamp is simple in structure and low in cost, and therefore is suited to be promoted and applied massively.
Description
Technical field
The utility model relates to a kind of LED fluorescent lamp, specifically, relates to a kind of LED fluorescent lamp that can regulate the color and the intensity of light.
Background technology
Traditional fluorescent lamp is to utilize light-emitting phosphor, respectively there is a filament at the fluorescent lamp two ends, are filled with the argon of trace and thin mercury vapour in the fluorescent tube, scribble fluorescent material on the tube inner wall, send ultraviolet ray during gaseous conduction between two filaments, make fluorescent material send soft visible light.Though it is simple in structure, cheap, exist many weak points: 1) fluorescent material and ultraviolet ray pollute environment, easily human body are damaged simultaneously; 2) damage easily, service life is short; 3) luminous efficiency is low, wastes energy.And its brightness and color also cannot be regulated.
Led light source is a kind of new green environment protection light source, and it is a utilization solid cold light source, and dazzle is little, radiationless, do not send harmful substance during use, the life-span is long, uses very flexible, can make the various forms of products of point, line, surface, its control is also very convenient, as long as adjust current/voltage, just arbitrarily light modulation, different photochromic combinations are changeful, can reach colourful dynamic change effect.
The utility model content
The purpose of this utility model overcomes the weak point of existing fluorescent lamp, and a kind of dimming LED fluorescent lamp that can regulate the color and the intensity of light is provided.
Dimming LED fluorescent lamp of the present utility model, comprise fluorescent tube, connecting line and switch, said fluorescent tube comprises transparent outer tube, is located at the lamp holder at transparent outer tube two ends, is located at the lamp base on the lamp holder, lamp base is connected on the switch by connecting line, it is characterized in that, is provided with the PCB wiring board in transparent outer tube inside, link to each other with lamp base, on the one side of PCB wiring board, be welded with a plurality of regularly arranged light emitting diodes, also comprise in addition being used to regulate electric current and voltage by adjustable potentiometer.
Preferably, said adjustable potentiometer and switch are connected in series.
Dimming LED fluorescent lamp of the present utility model adopts adjustable potentiometer, therefore can also can change the color of light by change voltage by changing the brightness that electric current changes light.
The utility model also has following technique effect except all advantages that possess the LED lamp:
1, can regulate the color and the brightness of light, further enlarge the range of application of LED lamp;
2, of the present utility model simple in structure, with low cost, be easy to large-scale promotion application.
Description of drawings
Come the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of dimming LED fluorescent lamp of the present utility model;
Fig. 2 is a working circuit diagram of the present utility model.
Wherein, 1 is outer tube, and 2 is lamp holder, and 3 is lamp base, and 4 is the PCB circuit board, and 5 is light emitting diode, and 6 is adjustable potentiometer, and 7 is fluorescent tube.
The specific embodiment
As shown in Figure 1, dimming LED fluorescent lamp of the present utility model comprises fluorescent tube
Connecting line and switch, said fluorescent tube comprises transparent outer tube 1, is located at the lamp holder 2 at transparent outer tube two ends, is located at the lamp base 3 on the lamp holder 2, lamp base 3 is connected on the switch by connecting line, be provided with PCB wiring board 4 in transparent outer tube 1 inside, link to each other with lamp base 3, on the one side of PCB wiring board 4, be welded with a plurality of regularly arranged light emitting diodes 5, also comprise adjustable potentiometer 6 in addition, be used to regulate electric current and voltage.Said adjustable potentiometer 6 is connected in series with switch.
Dimming LED fluorescent lamp of the present utility model in use, can also can change the color of light by change voltage by changing the brightness that electric current changes light.
Claims (2)
1. dimming LED fluorescent lamp, comprise fluorescent tube, connecting line and switch, said fluorescent tube comprises transparent outer tube, is located at the lamp holder at transparent outer tube two ends, is located at the lamp base on the lamp holder, lamp base is connected on the switch by connecting line, it is characterized in that, is provided with the PCB wiring board in transparent outer tube inside, link to each other with lamp base, on the one side of PCB wiring board, be welded with regularly arranged light emitting diode, also comprise in addition being used to regulate electric current and voltage by adjustable potentiometer.
