Description

A light source device for ship indication

1. Technical field

The invention belongs to the technical field of lighting optics and relates to a ship indicating light source device.

2. Background technology:

When the ship is sailing on the water, in addition to the modern communication means such as radio communication, the traditional light language plays an irreplaceable role in the transmission of information and orders. With the development of marine modernization, light signals still play a very important role in the communication between ships and between ships and carrier-based aircraft. Throughout the navies of various countries, while vigorously developing radio technology and communication, they still attach great importance to the research and development of traditional shipboard light box technology. At present, there are relatively standardized requirements for the emission angle and service life of shipboard light boxes in the world. In order to catch up with the international level as soon as possible in the field of shipboard light box research and development, we invented a new light source device for ship indication based on the existing non-imaging optical theory.

The known Chinese utility model patent No. 200320115436 discloses a "light-emitting diode integrated beacon light source", which solves the problem that the angle between the tubes and the tubes arranged in a ring is 45 degrees, which makes the complementary ability of luminous brightness poor and easy to produce dark corners. , so that the brightness of the 360-degree ambient light in the horizontal direction is uniform, without affecting the vision, but the angles of the horizontal and vertical directions cannot be controlled.

3. Contents of the invention:

The main purpose of this utility model is to use a halogen lamp as the light source of the light box, use an ellipsoidal reflective bowl to concentrate the energy of the light source, and constrain the angle of the light beam emitted by the light source through the slit, Fresnel lens and cylindrical mirror array, so that the light beam is in the The opening angle in the vertical direction is kept between 18' and 40', and the opening angle in the horizontal direction is kept between 40° and 60°.

In order to achieve the above purpose, the utility model provides a light source device for ship indication.

The detailed content of the utility model includes: a halogen light source 1, an ellipsoid reflective bowl 2, a slit group 3, a Fresnel lens 4, and a cylindrical mirror array 5. The halogen light source 1 is located at the focal position 6 of the ellipsoidal reflective bowl 2, the slit group 3 is located at the other focal position 7 of the ellipsoidal reflective bowl, and at the same time is located at the focal plane position 8 of the Fresnel lens 4, and the Fresnel lens is located on the cylindrical surface The focal plane position 9 of the mirror array.

In this way, the light emitted from the halogen light source 1 concentrates the energy of the light source through the ellipsoidal reflective bowl 2, and by adjusting the distance between the slit 3, the Fresnel lens 4 and the cylindrical mirror array 5, the angle of the light beam emitted by the light source is constrained, Keep the opening angle of the beam in the vertical direction between 18'~40', and keep the opening angle in the horizontal direction between 40°~60°.

The working process of the utility model: the light emitted from the halogen light source 1 in Fig. 1, the energy of the light source is concentrated through the ellipsoid reflective bowl 2, and the light beam emitted by the light source is passed through the slit 3, the Fresnel lens 4 and the cylindrical mirror array 5 Angle constraints are carried out so that the opening angle of the beam in the vertical direction is kept between 18'~40', and the opening angle in the horizontal direction is kept between 40°~60°.

Positive effect:

Due to the combination of Fresnel lens and cylindrical mirror array, it not only achieves the effect of fully homogenizing the outgoing beam in the horizontal and vertical directions, but also ensures the requirements of the outgoing angle, and uses the ellipsoidal reflective bowl to reduce the loss of light source energy. , so that most of the energy is concentrated in the slit, so that the light beam emitted from the light box can be seen within a certain distance and the color of the light can be distinguished. Moreover, the brightness is high, the energy consumption is low, the light is uniform, and the resolution is strong. The utility model has the advantages of simple and reliable structure, strong operability, and can be well applied to shipboard indication and flight landing aid systems.

According to accompanying drawings 1 and 2, a halogen light source 1, an ellipsoidal reflective bowl 2, a slit group 3, a Fresnel lens 4, and a cylindrical mirror array 5 are installed on the same optical axis. The halogen light source 1 adopts three light sources placed horizontally side by side. The halogen light source 1 is located at the focal position 6 of the ellipsoidal reflective bowl 2, the slit group 3 is located at the other focal position 7 of the ellipsoidal reflective bowl, and at the same time is located at the focal plane position 8 of the Fresnel lens 4, and the Fresnel lens is located on the cylindrical surface The focal plane position 9 of the mirror array.

In Fig. 1, the light emitted from the halogen lamp light source 1 concentrates the energy of the light source through the ellipsoidal reflective bowl 2, and by adjusting the distance between the slit 3, the Fresnel lens 4 and the cylindrical mirror array 5, according to the design requirements, the output of the light source is reduced. The beam is angle-constrained, increasing the distance between the slit 3 and the Fresnel lens 4 reduces the vertical angle of the outgoing beam, and reducing the distance between the slit 3 and the Fresnel lens 4 increases the vertical angle of the outgoing beam The opening angle keeps the opening angle of the light beam in the vertical direction at 18'±2'; 30'±2'; 40'±2' in the above three embodiments.

At this time, the interval between the cylindrical lens array 5 and the Fresnel lens 4 is increased to reduce the output beam. Horizontal opening angle, or reduce the interval between the cylindrical mirror array 5 and the Fresnel lens 4 to increase the horizontal opening angle of the outgoing light beam, so that the opening angle of the light beam in the horizontal direction remains at 40 °; 50 °; between 60 ° between.
