Description

Fireproof light fixture

Technical field

The invention relates to the field of illumination, and in particular to a fireproof lamp.

Background technique

The fire-proof lamps of the prior art are mostly made of a combination of an iron lamp cover, an aluminum radiator, a fire ring (made of a fireproof expansion material) and other materials, and the fire ring is attached to the inner wall and the bottom of the aluminum heat sink. In the event of a fire, the fire ring expands in contact with the fire and isolates the flame from the aluminum radiator to prevent the aluminum radiator from melting and the aluminum drop to fall and prevent the flame from rising.

However, prior art fire protection fixtures have the following drawbacks:

1. The expansion material of the fire ring is very light after expansion. Under the action of the hot air flow inside the fire field, the fire ring (expanding material) is easy to fall and fall, which will cause the fire ring to fail, which will lead to the failure of the fire protection effect of the lamp;

2. Since the fireproof expansion material is very light after expansion, the fireproof ring has no bearing capacity after expansion. When the aluminum material melts and falls, the aluminum drop will blow the fire ring (expanding material) to the fire field, which will also lead to the fire ring. The fire barrier fails, which in turn causes the fire protection of the luminaire to fail;

3. In the prior art, the fire ring (expanding material) is attached to the inner wall of the aluminum heat sink by double-sided adhesive bonding. However, since the temperature of the heat sink is generally above 80 ° C when the fire protection lamp is working, the double-sided tape is easy to age at this temperature state, and the fire ring (expanding material) has the hidden danger of falling off; and the aluminum radiator is completed. Afterwards, there will be chemical residues. These residual chemicals also have a certain influence on the adhesive properties of the double-sided tape. In addition, in the prior art, the process of applying double-sided tape is manually operated, and manual operation requires visual inspection and time consuming. And labor costs are high.
