technical field

The utility model relates to an LED lamp for lighting, in particular to an LED lamp tube with a two-color lamp shell.

Background technique

LED (light-emitting diode) lamps have gradually replaced traditional high-energy-consumption lamps, such as fluorescent lamps and incandescent lamps, because of their low energy consumption and high brightness, and have gradually become popular in people's daily life. With the development of LED technology, the energy consumption and heat dissipation of LED lamps need to be reduced. Now various companies are researching various LED lights to meet people's different needs for LED lights on different occasions.

The biggest advantage of LED lamps is energy saving and environmental protection. The luminous efficiency reaches above 100lm/W, while ordinary incandescent lamps can only reach 40lm/W, and energy-saving lamps hover around 70lm/W. Therefore, with the same wattage, LED lamps will be much brighter than incandescent lamps and energy-saving lamps. The brightness of a 1-watt LED light is equivalent to about 2 watts of energy-saving lamps, and the 5-watt LED light consumes 5 degrees of electricity for 1000 hours. The life of the LED light can reach 50,000 hours, and the LED light has no radiation.

Due to the structure of the PCB board itself, the effect of the heat-conducting glue and the heat sink of the LED light bar is yet to be tested.

At present, in the existing LED lamps, the substrate and the lamp body are usually fixed by glue or bolts, which takes more time to assemble and hinders the improvement of production efficiency; in addition, the lampshade adopts the method of buckle or clip fixed, there is a risk of detachment.

The power supply lamp head is equivalent to a socket, and the connecting lamp head on another LED tube connected in series can be inserted into the power supply lamp head Electrical connection.

Preferably, the lamp holder includes a side plate and a clamping part extending into the lamp body, a buckle is provided on the side of the clamping part, and the lamp body has a slot matching the buckle.

One side of the buckle is a slope for insertion guide, and the buckle is pushed into the slot, that is, the lamp cap is fixed on both ends of the lamp body.

Preferably, the width of the lamp body is greater than that of the lampshade, and a concave reinforcing part is provided at the position corresponding to the pipe body and the slot.

In order to ensure sufficient structural strength, the size of the lamp body is large, which is convenient for the installation and fixation of the lamp. The concave reinforcement part is equivalent to the reinforcing rib on the lamp body, which further improves the bending resistance of the lamp body in length.

Preferably, two limiting plates are arranged inside the reinforcing part, and the slot is located between the two limiting plates, that is, the substrate is clamped between the two limiting plates.

Preferably, there is an opening angle between the two limiting plates, which facilitates the insertion of the substrate and reduces the resistance of installing the substrate.

Preferably, both sides of the back of the lamp body are provided with protrusions for engaging and fixing, and the protrusions extend along the length of the lamp body, and cooperate with corresponding snap rings to fix the lamp.

Preferably, a switch is installed on the side of the lamp body, and the switch is connected to the driving power in the lamp body to control the lighting on and off of the lamp.

The utility model has the advantages of simple structure and convenient assembly. The lamp body and the lampshade are integrally formed to avoid the risk of the lampshade falling off.
