Circular vehicle-mounted LED emergency lighting lamp

Abstract

A circular vehicle-mounted LED emergency lighting lamp solves the problems that in the prior art, cooling fins are arranged on a lower shell and a rear cover, an upper shell, the lower shell and the rear cover cannot be interchanged, the machining cost is high, and the size is large. The circular vehicle-mounted LED emergency lighting lamp is characterized in that universal front-and-back symmetrical end covers are installed on the front side and the rear side of a barrel-shaped radiator, a double-sided aluminum substrate is installed in the barrel-shaped radiator, an LED lamp driving circuit and LED lamp beads are welded to a front panel of the double-sided aluminum substrate, an LED lamp driving circuit is welded to a rear panel of the double-sided aluminum substrate, and a columnar radiator is installed on the rear panel of the double-sided aluminum substrate. The circular vehicle-mounted LED emergency lighting lamp has the advantages that interchangeability of the front end cover and the rear end cover is good, one double-sided aluminum substrate is adopted to serve as a lamp panel and a driving circuit board, and the double-sided aluminum substrate also serves as an installation plate for heat radiating columns; the columnar radiator and the barrel-shaped radiator are combined and connected with each other through heat-conducting glue, the heat radiating area is increased, the heat radiating speed is high, the sealing and waterproof effects are good, the structure is simple, the size is small, the weight is light, and the circular vehicle-mounted LED emergency lighting lamp is suitable for serving as a vehicle-mounted LED emergency lighting lamp.

Description

technical field [0001] The invention belongs to the technical field of LED lighting lamps, in particular to a circular vehicle-mounted LED emergency lighting lamp installed on a vehicle for emergency lighting at night. Background technique [0002] When emergencies occur at night, such as night fires, accidents, public security, accident investigation and night emergency lighting, it is necessary to provide night mobile emergency lighting preparations.

Problems solved by technology

[0003] In the prior art, there is a kind of LED strip light, which is mainly used for refitting glare lighting on the roof of off-road vehicles, used as SUV off-road vehicle spotlights, off-road vehicle headlights, engineering vehicle lighting work lights, etc., using American CREE lamp beads , 10-30V wide voltage design, aluminum alloy shell, aluminum alloy bracket, can also be widely used in car lights, truck lights, off-road lights, mechanical lights, agricultural machinery, ambulance lights, engineering lights, logging lights , Excavator lights, forklift lights, coal mine lights, snowplow lights, hunting lights, armored lights, tank lights and other vehicle lighting and industrial and mining sites, the problem is that the power is small, using 48PCS×3WLED High-power American Kerui lamp beads have a narrow lighting range, which cannot meet the needs of emergency lighting at night, especially the light source groove is a closed groove. When working, the heat generated by the LED lamp makes the light source groove inside and outside. Unbalanced pressure will easily cause stress deformation of the sealing rubber ring, accelerate aging, and make the seal invalid. External moisture, moisture and dust will easily enter the light source groove, causing fog and water droplets inside the light source groove, affecting the lighting effect

This utility model has high power and wide lighting range, but the utility model has a complex structure. First, the cooling fins are arranged on the lower case and the back cover, and the upper case, the lower case and the back cover cannot be interchanged, and they need to be installed separately. Processing, the processing cost is high, the 2nd, because the light source groove is also a closed groove, when working, due to the heat generated by the high-power (150W) LED lamp, the pressure inside and outside the light source groove is unbalanced, and it is easy to make the sealing rubber ring It will cause stress deformation, accelerate aging, and make the seal invalid. External moisture, moisture and dust will easily enter the light source groove, causing fog and water droplets inside the light source groove, which will affect the lighting effect. There are symmetrical installation holes for waterproof and breathable valves. When in use, install waterproof and breathable valves to balance the pressure inside and outside the light source groove. Third, the utility model installs an LED aluminum substrate welded with LED lamp beads at the bottom of the light source groove. The circuit board is installed in the circuit board installation cavity on the back cover. When in use, the circuit board power cord is drawn out from the circuit board power cord outlet hole and the plug, and waterproof sealant is poured into the plug. At the same time, the LED aluminum substrate power cord is passed through The LED aluminum substrate power line threading hole passes through and connects with the circuit board. Therefore, the LED aluminum substrate (light board) and circuit board (driver board) need to be used respectively. The above three aspects make the utility model not only complex in structure, but also large in size.
