Technical Field

The invention relates to the technical field of aviation obstruction lamps, in particular to an optical device with an adjustable vertical angle.

Background

According to the national standard, an aviation obstruction light (AviationObstructionlight) is required to be arranged on a fixed object which is higher than the ground of a peripheral region by more than 45 meters so as to indicate the existence of the obstruction. The aviation obstruction light is different from common lighting light, the aviation obstruction light is mainly divided into three categories of high light intensity, medium light intensity and low light intensity according to the light intensity by taking flashing with a certain frequency as a working mode, wherein the A, B type low light intensity aviation obstruction light and the C type medium light intensity are constant light; C. the D-type low-light-intensity working mode is flashing; A. the working modes of the B-type medium-light-intensity aviation obstruction light and the A, B-type high-light-intensity aviation obstruction light are flashing. C. The D-type low-light-intensity flash frequency is 60-90 times per minute; A. the flash frequency of the B type medium light intensity is 20-60 times per minute; A. the flash frequency of B-type high light intensity is 40-60 times per minute. The aviation obstruction light is used for marking the existence of an obstruction, such as marking the outline and the height of a structure, so that an aircraft operator can judge the height and the outline of the obstruction to play a role in warning.

According to the standard of aviation obstruction lights, light signs and other horizontal planes are regulated to emit light in 360 degrees in the technical standard of civil airport flight areas. The requirements of different light intensity values are respectively met under the condition of meeting the light emitting of 360 degrees on the horizontal plane, the aviation obstruction light needs a high-power light source because the light intensity is required to reach certain intensity, the obstruction light source in the current market mainly comprises a xenon lamp tube and an LED, the xenon lamp tube has the advantages and the disadvantages of high brightness, high luminous flux, good color rendering property, good light penetration, low requirement on heat dissipation and suitability for outdoor light; the LED lamp beads are durable and small in size, but the requirement on heat dissipation is high, and when the LED lamp beads are selected, the appropriate barrier lamps are selected to be applied according to factors such as lamp structures and economic cost.

Most of the existing aviation obstruction lamps adopt a fixed mode, the vertical direction light-emitting angle of the obstruction lamp adopting the fixed mode is also fixed, if the vertical direction light-emitting angle needs to be enlarged, only an optical device can be replaced, namely, only the whole lamp can be replaced, and the vertical direction light-emitting angle and the intensity of the obstruction lamp are inconvenient to adjust.
