Description

LED glass tube

technical field

The utility model relates to the field of LED lighting, in particular to an LED glass lamp tube.

Background technique

At present, the tubes of LED lamps are generally "half-plastic and half-aluminum" structures. The tubes are made of aluminum alloy and PC (polycarbonate) cover. The "flat strip" driving power is placed in the aluminum alloy semicircular cavity. The light from the board exits through the PC cover. To sum up, lamps with this structure will mainly face the following two problems during the production and maintenance process:

(1) The assembly efficiency is low.

1. When assembling, it is necessary to add an insulating protective layer to the "flat and long strip" power supply and then insert it into the semicircular aluminum alloy.

2. When assembling, it is necessary to assemble the aluminum alloy and the PC cover together.

(2) Poor security.

The cost of non-isolated power supply is lower than that of isolated power supply, but the efficiency is higher than that of isolated power supply. Therefore, most LED lighting tubes use non-isolated power supply. The 220V AC passes through the non-isolated power supply and reaches the output end of the power supply to supply power for the LED light board. There is only a very thin insulating layer between the aluminum base plate of the lamp board and the aluminum alloy of the lamp housing for isolation, and there is a risk of electric shock when touching the load.
