Explosion-flashing type LED (light emitting diode) warning lamp

Abstract

The invention discloses an explosion-flashing type LED (light emitting diode) warning lamp. The explosion-flashing type LED warning lamp comprises a lampshade and a base, wherein the lampshade and the base are sealed through a sealing ring; an upper reflecting mirror, an upper LED light source module, a lower LED light source module and a lower reflecting mirror are sequentially arranged in the lampshade from top to bottom; a power plate is fixed on the base; a light source of the upper LED light source module backs to a light source of the lower LED light source module; a reflecting surface of the upper reflecting mirror is opposite to a reflecting surface of the lower reflecting mirror; each of the upper LED light source module and the lower LED light source module is provided with a plurality of LED light source particles; the LED light source particles are uniformly distributed on a circuit board peripherally; each of the upper reflecting mirror and the lower reflecting mirror is provided with a plurality of reflecting surfaces; the reflecting surfaces are also uniformly distributed peripherally; each reflecting surface corresponds to the corresponding LED light source particle; each reflecting surface of each reflecting mirror is a paraboloid of revolution; and the LED light source particles are placed on the focus of the paraboloid. The working mode of the warning lamp is a stroboflash lighting mode; and the service life of the lamp is determined by LED, so that the service life of the lamp is greatly prolonged.

Description

technical field [0001] The invention relates to a signal device, in particular to a warning lamp. Background technique [0002] Most of the existing LED warning lights use multiple LED light sources, and these LEDs are grouped and welded on multiple PCB boards, and then the multiple PCB boards are surrounded into a polygonal column to realize the 360° light emission of the lamp around its axis. For lamps with this structure, the utilization rate of the light emitted by the LED light source is not high. In order to make the light distribution performance of the lamp meet the requirements of the corresponding standards, the number of LED light sources often needs to be large, and they may be high-power LEDs, which will greatly increase The cost of the lamp; at the same time, the structure of this lamp is complex and the assembly is cumbersome. [0003] The invention patent CN202884742U applied by the applicant is an improvement on the above problems. The structure of the lamp...

AI Technical Summary

Problems solved by technology

The disadvantage of this technical solution is that a DC motor is used in the structure of the lamp to drive the circular rotation of the reflector, but the life of the DC (with brush) motor is short, and the longest can be about 1500-2000h, and the motor is installed in the lamp. It is inconvenient to replace the interior, which seriously affects the service life of the whole lamp; and the motor will generate noise during the process of driving the reflector, and there is a potential risk of failure if it is affected by vibration during the transmission process (such as abnormal rotation frequency or stop rotation Wait)
