Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision lamps, in particular to an anti-collision lamp adopting an aviation color high-power SMD double-chip LED light source. Background Art

[0002] The anti-collision lights used in aircraft are strobe lights with a frequency of 45 times per minute and the color is aviation red. They are installed on the top of the rudder and under the fuselage to provide the position of the aircraft. Currently, the anti-collision lights used can be divided into three types according to the light source, namely incandescent light bulb anti-collision lights, xenon pulse anti-collision lights, and LED light source anti-collision lights.

[0003] Most of the existing aircraft use incandescent bulb light source anti-collision lamps or xenon pulse anti-collision lamps, but the use of these two types of anti-collision lamps has certain disadvantages. The main reason is that the incandescent bulb light source anti-collision lamp is prone to short filament and failure to light up during use due to the tungsten filament structure of the bulb; the xenon anti-collision lamp requires tens of thousands of volts of high voltage to be applied to both ends of the xenon lamp tube to ionize the xenon gas, thereby emitting high-intensity bright light. During the entire discharge process, electromagnetic interference is easily generated due to the presence of high-voltage pulses. Therefore, technical personnel in this field provide an anti-collision lamp using an aviation-colored high-power SMD dual-chip LED light source to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and an anti-collision lamp using an aviation-color high-power SMD dual-chip LED light source is proposed. The anti-collision lamp using an LED light source has great advantages, because the LED emits light by the recombination of electrons and holes in the internal PN junction to produce bright light, and has neither high voltage nor filament, which can solve the shortcomings of incandescent bulb light source anti-collision lamps and xenon pulse anti-collision lamps. The anti-collision lamp uses an LED light source, and the light source uses a special dual-chip light source, which meets the space requirements of brightness while meeting the smaller volume.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an anti-collision lamp using aviation color high-power SMD dual-chip LED light source, including a lamp heat dissipation housing, a lamp lower housing, a power supply and an input power supply, characterized in that: the outer surface of the lamp heat dissipation housing is fixedly connected with a side light source panel assembly all around, and the upper end surface of the lamp heat dissipation housing is fixedly connected with a top light source panel assembly;

[0006] The power supply circuit is connected to a resistor and a drain of the MOS tube IFR1010NS, and the input power supply circuit is connected to a voltage protection element.

[0007] Through the above technical solution, the anti-collision lamp with a dual-chip LED light source composed of multiple components has the characteristics of compact structure, small size, light weight, simple installation and reliability, and in the driving circuit, it can be realized that when the voltage in the circuit increases, the voltage drop on the current-limiting wire will increase to ensure that the subsequent light source has a constant power supply. On the contrary, when the voltage in the circuit decreases, the voltage drop on the current-limiting wire will decrease, so that the power supply of the lamp bead remains constant, and the flashing of the lamp is realized, and in the LED driver surge suppression circuit, when a high voltage or lightning pulse occurs, the voltage protection element is turned on, and the high voltage in the circuit is instantly discharged to the ground, protecting the safety of the subsequent circuit.

[0008] Furthermore, a circuit board assembly is fixedly connected to the lower end surface of the lamp heat dissipation housing;

[0009] Through the above technical solution, heat accumulation can be prevented through the action of the circuit board assembly, and the reliability of the lamp can be improved.

[0010] Further, a first waterproof silicone ring is fixedly connected to the upper surface of the lamp heat dissipation housing, a lamp upper ring is fixedly connected to the upper surface of the lamp heat dissipation housing, and a red lampshade is fixedly connected to the upper surface of the lamp heat dissipation housing;

[0011] Through the above technical scheme, the waterproof effect can be achieved to a certain extent under the action of the waterproof silicone ring, and the light transmittance of the anti-collision lamp can be increased under the action of the lamp upper ring and the red lampshade, and the anti-aging property can be enhanced to a certain extent.

[0012] Furthermore, an electrical connector is fixedly connected to the lower end surface of the lower housing of the lamp;

[0013] Through the above technical solution, the electrical connector can provide sufficient power for the entire anti-collision lamp, thereby ensuring that the anti-collision lamp can work normally.

[0014] Furthermore, a cross-slot pan head screw is threadedly sleeved on the lower end surface of the lamp lower housing;

[0015] Through the above technical solution, the electrical connector can be fixed together with the lower housing of the lamp by the action of the cross-recessed pan head screw.

[0016] Furthermore, the lower end surface of the lamp heat dissipation housing is fixedly connected to the lower housing of the lamp by a second cross recessed countersunk screw;

[0017] Through the above technical solution, the heat dissipation housing of the lamp and the housing below the lamp are fixed together by the action of the second cross recessed countersunk screw, so that the two can be connected together to ensure normal operation.

[0018] Furthermore, a first cross-slot countersunk screw is threadedly sleeved on the upper end surface of the lamp heat dissipation housing, and a second waterproof silicone ring is fixedly connected to the lower end surface of the lamp heat dissipation housing;

[0019] Through the above technical scheme, the upper ring of the lamp, the red lampshade, the first waterproof silicone ring and the lamp heat dissipation shell are fixedly connected together under the action of the first cross-slot countersunk screw, and the main function of the second waterproof silicone ring is to provide waterproof effect for the connection between the lamp heat dissipation shell and the lower shell of the lamp.

[0020] Furthermore, a cross-recessed cylindrical head screw is threadedly sleeved on the lower end surface of the lamp heat dissipation housing;

[0021] Through the above technical solution, the circuit board assembly can be fixedly connected to the main body of the lamp heat dissipation housing by the action of the cross-recessed cylindrical head screw.

The lamp can work normally. An anti-surge impact module is used to accurately protect the subsequent electroluminescent light source, preventing surge damage caused by overvoltage impact, ensuring the safety and reliability of the circuit, and having good electromagnetic compatibility. At the same time, it will not pollute the electromagnetic environment. BRIEF DESCRIPTION OF THE DRAWINGS
