LED fluorescent tube and lamp holder

technical field

The utility model relates to the field of lighting fixtures, in particular to an LED fluorescent lamp tube and a lamp holder.

Background technique

With the rapid development of LED (Light Emitting Diode) technology, the proportion of LED light sources in the lighting market is increasing. The trend of LED fluorescent lamps replacing ordinary fluorescent lamps is becoming more and more obvious. After years of development and accumulation, LED lighting technology has shown excellent energy-saving effects. As an emerging lighting fixture, LED fluorescent lamps have the advantages of small size, low energy consumption, low calorific value, long life, and environmental protection.

The LED fluorescent tubes on the market include two end caps and an intermediate component fastened by the two end caps. During the use of this LED fluorescent tube, current can flow from one end cap through the intermediate component to the other end cap directly. When the installer disassembles this kind of LED fluorescent tube, if one end cover of the LED fluorescent lamp has been stuck into the live wire interface, then the other end cover of the LED fluorescent tube must have been charged. Metal presents a shock hazard. And this LED fluorescent tube does not meet the European safety regulations.

Chinese invention patent CN201010598932.2 also discloses an LED fluorescent tube. This LED fluorescent tube mainly improves the heat dissipation structure, but the power supply circuit of this LED fluorescent tube is still that the current flows from an end cover through the intermediate device directly to the Another end cap, the safety issue of installers when disassembling LED fluorescent tubes is still unresolved.

Utility model content

The technical problem to be solved by the utility model is to provide an LED fluorescent tube that can be safely disassembled on the basis of the above-mentioned LED fluorescent tube. For this reason, the utility model also provides a lamp holder for installing the LED fluorescent tube.

The technical scheme of the utility model for the LED fluorescent tube is: an LED fluorescent tube, including a lampshade, an LED light source assembly, an LED drive assembly, a heat dissipation shell, and two end covers with a pair of terminal posts, the lampshade and the heat dissipation The shell is connected, and the two end covers are respectively fastened to the two ends of the connected lampshade and the heat dissipation shell, the LED light source assembly is installed on the heat dissipation shell, and the LED driving assembly is connected to drive the LED light source assembly to work , the two end caps include a power inlet end cap and a short-circuit end cap, one terminal of the power inlet end cap is electrically connected to a power access terminal of the LED driver assembly, and the other terminal of the power inlet end cap It is electrically connected with the other power access terminal of the LED driver component, and the two terminals of the short-circuit end cover are electrically short-circuited.

The technical proposal of the utility model for the lamp holder is: a lamp holder for installing the LED fluorescent tube, including a socket for detachably installing a starter, and the lamp holder also includes a fuse, the fuse A replacement starter is removably mounted on the socket.

The beneficial effects of the utility model are as follows: 1. Since one terminal of the power inlet end cover is electrically connected to a power access terminal of the LED drive assembly, the other terminal of the power inlet end cover is connected to another power supply terminal of the LED drive assembly. Incoming terminals are electrically connected, that is, the LED drive components are unilaterally powered by the power supply end cover, and there is no direct conduction between the power supply end cover and the short-circuit end cover. Therefore, when the installer disassembles, any end cover must first Carded into the live wire interface, the other end cap will not be charged, and it also meets the requirements of European safety regulations; 2. Since the starter in the traditional lamp holder is replaced by a fuse, after plugging in the fuse, the live wire After short-circuiting the end cover, the fuse, one terminal of the power supply end cover, the LED drive component, and the other terminal of the power supply end cover to reach the neutral line, a power supply circuit is formed to ensure the normal operation of the LED fluorescent tube; 3. Since the external structure of the two end caps of the LED fluorescent tube has not changed, the LED fluorescent tube can be directly installed on the traditional lamp holder. Therefore, only the starter of the traditional lamp holder is replaced with a fuse to make the LED fluorescent lamp tube work, reducing the cost of replacing lamp holders and saving resources.
