Description

A kind of T8 type LED lamp replacing T8 type fluorescent lamp

technical field

The utility model relates to an LED lamp, in particular to a T8-type LED lamp which replaces the T8-type fluorescent lamp.

Background technique

With the shortage of energy in the world, the whole world is talking about low carbon, so green energy-saving lighting electrical products are widely used, and the original T8 fluorescent lamp is the most widely used in the market. With the promotion of green energy-saving products and the third generation of energy-saving With the emergence of LED products, such fluorescent tubes will be phased out. Existing this fluorescent tube has following shortcoming:

1. The lamp tube is fragile;

Second, the lamp contains mercury, which is harmful to the environment and the human body;

Three, the lamp life is short;

Fourth, the lamp tube has a negative resistance characteristic, and requires a high voltage to start the glow when starting.

Utility model content

The main purpose of the utility model is to overcome the shortcomings of the T8 fluorescent lamp in the prior art, and provide a T8 LED lamp that replaces the T8 fluorescent lamp, and its power consumption is lower while maintaining the same brightness.

The utility model adopts the following technical solutions:

A T8-type LED lamp replacing a T8-type fluorescent lamp, which mainly includes a housing, a lampshade, two lamp caps, an LED light source composed of a plurality of light-emitting diodes, and an electronic circuit board. The two lamp caps are provided with a power plug, and the electronic circuit board integrates There is a constant current step-down circuit, the input terminal of the electronic circuit board is connected to the plugs of the two lamp caps, the output terminal of the electronic circuit board is connected to the LED light source; the LED light source is fixed on the housing, and the lampshade is set on the LED On the light source, the two lamp holders are respectively arranged at two ends of the casing.

The housing is a cast aluminum profile, which is a cylindrical body with a cavity composed of an arc-shaped plate and a flat plate. The electronic circuit board is accommodated in the cavity, and the LED light source is installed on the flat plate .

From the above description of the utility model, it can be seen that compared with the prior art, a T8-type LED lamp of the utility model, which replaces the T8-type fluorescent lamp, drives the LED light-emitting diode to emit light through a constant current step-down circuit, and then is diffusely reflected by the lampshade. Injection, the heat generated by the light-emitting diode is dissipated by the cast aluminum profile. Compared with the T8 fluorescent lamp, it has the advantages of high brightness, long life, low energy consumption, and low overall power consumption. It can completely replace the existing T8 fluorescent lamp.
