Description

BACKGROUND OF THE INVENTION

1. Technical Field

The invention relates to the field of tri-proof lamps, in particular to an extrusion-type tri-proof lamp.

2. Description of Related Art

Tri-proof lamps are illuminating lamps with a water-proof function, a dust-proof function and a corrosion-proof function, and have been widely used in factories, offices, metros, airports and other special occasions with water-proof, dust-proof and corrosion-proof requirements. Generally, the tri-proof lamps are produced by injection-molding or extrusion. Different molds are needed for injection-molding of tri-proof lamps with different sizes, which makes the investment cost high. Extrusion-type tri-proof lamps with any lengths can be fabricated without any mold. Most existing extrusion-type tri-proof lamps are of an integrated structure, and wiring holes are reserved only in two sides of the extrusion-type tri-proof lamps to allow electricians to assemble or disassemble wires; a small part of the tri-proof lamps are provided with a detachable battery, but the drive module, the light source module, and a microwave sensor are undetachable. The tri-proof lamp is expensive and will not be able to function normally once one part is broken, so the use effect is compromised, and even the whole lamp will be discarded, thus causing resource waste and increasing the use cost due to the replacement with a new lamp. In addition, wires are connected into the existing extrusion-type tri-proof lamps from two sides, so the overall wiring is disordered, and the use effect and overall appearance of the lamps are compromised.
