Rotatable LED (light emitting diode) double-sided daylight lamp with external power supply

Abstract

The invention discloses lighting equipment, and particularly relates to a rotatable LED (light emitting diode) double-sided daylight lamp with an external power supply. The daylight lamp comprises two upper tube heads, two lower tube heads, a heat radiator and two LED lamp plates, wherein the heat radiator takes the shape of a square tube; a heat radiating chamber is formed in the center of the square tube shaped heat radiator; the two LED lamp plates are arranged at the two sides of the heat radiating chamber and are mutually symmetric; layer isolating plates are arranged inside the two lower tube heads; line holes are formed in the layer isolating plates; through holes are formed in the side walls of the two upper tube heads; power supply sockets are arranged inside the through holes in a plugging mode; the body parts of the power supply sockets are arranged inside the upper tube heads and are fixed with the upper tube heads through connecting plates; and an elastic pressing plate on each power supply socket penetrates through the line hole of the corresponding lower tube head and is electrically connected with the LED lamp plate. Therefore, the technical defects that the heat radiation effect of the double sides of a rotatable LED with the external power supply is poor, the electric connection mode between an LED lamp source and the external power supply is complex and the use stability is poor are overcome.

Description

technical field [0001] The invention relates to a lighting device, in particular to a rotatable LED double-sided fluorescent lamp with an external power supply. Background technique [0002] Due to its advantages of environmental protection, energy saving, small size, fast response, and long life, LED is regarded as the lighting source in the 21st century. Therefore, it has gradually replaced traditional light sources and is used in traditional lighting devices. LED double-sided fluorescent lamps are one of them. [0003] There are many deficiencies in the LED double-sided fluorescent lamps currently on the market, which are mainly manifested in the following aspects: [0004] 1) The heat dissipation aluminum tube of the existing LED double-sided fluorescent lamp is in the shape of a plate. When two LED lamp panels are installed on the front and back of the plate-shaped heat dissipation aluminum tube at the same time, the heat dissipation performance is poor; [0005] 2) C...

AI Technical Summary

Problems solved by technology

[0004] 1) The heat dissipation aluminum tube of the existing LED double-sided fluorescent lamp is in the shape of a plate. When two LED lamp panels are installed on the front and back of the plate-shaped heat dissipation aluminum tube at the same time, the heat dissipation performance is poor;

[0005] 2) Considering that when LED double-sided fluorescent lamps work, the heat generated by them is almost twice that of LED single-sided fluorescent lamps, so LED double-sided fluorescent lamps usually adopt an external power supply structure in structural design, but the above-mentioned external power supply LED For double-sided fluorescent lamps, the electrical connection between the LED light source and the external power supply is cumbersome, and the stability of use is poor.
