Long warning lamp

Abstract

The invention discloses a long warning lamp. An upper section cover of the long warning lamp is formed by connecting an upper front cover (21), an upper middle cover (22) and an upper rear cover (23) in turn, wherein connecting joints of the upper front cover and the upper middle cover are connected with each other through concave convex buckle type structures (1) at a fixing bracket (3); a rubber strip is arranged and a water discharge passage (18) is formed between the connected concave convex buckle type structures; a water discharge groove (29) which is connected with the water discharge passage is formed at a junction between the upper front cover and the upper middle cover; and a lower section cover of the long warning lamp is formed by connecting a lower front cover (26), a lower middle cover (25) and a lower rear cover (24), wherein lamp housing convex buckles (28) and lamp housing rubber strips are arranged at two ends of a front lamp housing and a rear lamp housing and at the junctions of the two ends and the upper front cover and the lower front cover; and the bottoms of the lower front cover and the lower rear cover are provided with water through holes (19) which are communicated with a junction of the lamp housing convex buckles. In the long warning lamp, a control circuit board in the warning lamp can be protected from being invaded by rain water to the greatest extent, an internal environment is kept clean and is not polluted by dust, the service life of the warning lamp is prolonged, and a warning effect of the warning lamp is enhanced.

Description

1. Technical field [0001] The invention relates to a warning lamp, in particular to a long row of warning lamps used on vehicles. 2. Background technology [0002] At present, the long rows of warning lights used by vehicles are generally installed on the outer top of the vehicle, which include upper and lower aluminum profile covers, lampshades, lamps, control circuit boards, etc. The long row of warning lights are equipped with switches on the outside, which are connected to the inside of the vehicle through the switch power line. The cigarette lighter power supply makes the lamp work and emit light, which plays a certain warning role. When the vehicle is driving in rainy days, the long row of warning lights will be impacted by heavy rainwater. The existing problem is: due to the unreasonable design of the original structure, rainwater easily enters the inside of the long row of warning lights, damages the internal control circuit board, and reduces the service life of the...

Problems solved by technology

When the vehicle is driving in rainy days, the long row of warning lights will be impacted by heavy rainwater. The existing problem is: due to the unreasonable design of the original structure, rainwater easily enters the inside of the long row of warning lights, damages the internal control circuit board, and reduces the service life of the product.

And dust is also easy to enter the warning lights, resulting in poor warning effects, which is not conducive to driving safety, and the maintenance procedures are complicated and there are certain safety hazards
