Description

A New Type of LED Fluorescent Lamp

technical field

The utility model relates to a fluorescent lamp, in particular to an LED fluorescent lamp.

Background technique

As a sunrise industry, LED lighting has been widely used in various occasions; in recent years, LED technology has made breakthroughs in various aspects, and the luminous rate of LED has also been greatly improved. Therefore, LED lighting is very popular in the lighting market.

At present, the AC input of LED fluorescent tubes is generally connected by insulated wires. The wiring method is to weld two wires of different colors to the lamp holders (N, L) of the lamp respectively; the output end is directly welded to the positive and negative poles of the PCB circuit board; However, this connection method has the following defects: 1), the production process of LED lamp tubes increases, the production capacity is low, and the cost is too high; 2), there will be a visual blind area inside the lamp cap during the assembly process; 3) the combination between the lamp cap and the aluminum groove The insulating rubber of the local wires is easily broken, causing the wires to be connected to the metal casing, causing leakage and potential safety hazards. Existing LED fluorescent lamps are all assembled with screw connections and reinforcements. There are many processes, and the screws are easy to slip, and the insulated wires are easy to be locked and broken, further increasing the risk of leakage. The existing LED fluorescent lamps all have a structure in which the power circuit device and the LED lamp bead are separated. The power circuit device is installed between the PCB circuit board and the lamp holder. Since the power circuit device has a certain height, the distance from the PCB circuit board to the lampshade is very short. The light is not easy to disperse, resulting in the occurrence of spot-like spots and glare.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present utility model.

As shown in Figure 1, the utility model includes a lamp holder, an LED power supply and a PC tube. LED power supply pin 7 is inserted into the hollow pin 1 of the lamp head; the LED power supply is placed in the power rail groove 4 of the lamp head; the power supply anti-falling buckle 6 fixes the LED power supply, and the output line of the other end of the LED power supply is connected to the patch on the light board 12 in the PC tube The terminal male and female heads 13 are connected; the lamp head and the PC tube are fixedly connected to the fixing hole 10 through the fixing buckle 9 .

Among them, the lamp holder includes hollow pin 1 at the end, reinforcing rib 2, positioning rib 3, power rail groove 4, power supply anti-falling buckle 5, power supply anti-falling buckle 6, LED power pin 7, positioning pin 8 and fixing buckle 9. SMD terminal male and female head 13
