Description

Semiconductor emitter for circular navigation lights

The proposed utility model relates to signaling devices for navigation equipment of waterways, namely, to emitters of floating and coastal navigation signs.

Known light sources for navigation lights - signal lamps type SGV at a voltage of 2.5 V, used in typical light signal devices of circular action ESPK-75M 1.

A significant drawback of these lamps is that to create colored signal lights, it is necessary to install color filters, which, due to the low light transmittance (15 ... 30%), lead to increased energy consumption, and thereby to increased consumption of rechargeable batteries. Another disadvantage of the lamps is their low reliability and low service life (not more than 1000 hours).

The closest analogue in technical dryness and the achieved effect to the proposed device and adopted as a prototype is the light source used in the navigation light signal device for river conditions 2. It is made of one standard LED installed along the vertical axis of the cylindrical Fresnel lens and an annular reflective prism , which is installed in the focus of this Fresnel lens and turns the light flux of the LED into the horizon plane.

The disadvantage of the described device is the difficulties associated with the need to combine the axes of three optical elements: LEDs, prisms and Fresnel lenses. The obtained light intensity at the output of the light-signal installation is very small.

The essence of the utility model and its essential features

The proposed utility model is an LED emitter for circular navigation lights. The essence of the proposed utility model lies in the fact that it solves the problem of creating a colored (red, yellow, green and white) signal light in it by simple means.

the prevailing icpyronjiiM radiation due to the presence of a replicagel in the polymer casing (Fig. 1a). The emitting crystal is installed inside the lateral radiation reflector integrated in the holder (hc), in connection with which the predominant part of the light flux is directed to the conical reflector of the polymer case and is deployed by it into the horizontal plane. A pie chart on the direction of the radiation of the LED is shown in Fig. 16. Presented today is tucked into place on a zero rack (see Fig. 1c) with one confining disk and is mounted in the focus of a cylindrical Fresnel lens. As a result, at the output of the light-signaling device, the required power is obtained and the radiation angle in the vertical plane is 29 °, degrees.

It is possible to replace the emitter when the LED is mounted not on a hollow post, but on a standard lamp base (for example, BA15S / 19).

For a different operating current, a resistor is installed separately with an LED, which provides an indirect current in the range of 25 ... 60 mA and a working voltage of 2.5 ... 4 V. The consumed electric power does not exceed 0.15 W.

Brief description of the construction of the model

A description of a useful model of a semiconductor emitter for circular navigation lights is illustrated in the drawing, where in Fig. Figure 1a shows a general view of the LED, in Fig. 16 is a radiation pattern of the LED, and in Fig. 1c is a circular emitter device.

The LED contains a radiating crystal 1 located in the built-in lateral radiation reflector, a polymer housing 2 with a conical reflector 3. The emitter contains a LED 4, a hollow rack with one enclosing disk 5, and terminals 6.

The LED emitter operates as follows. The direct current from the Hstap source is supplied via flexible leads 6 through a current-limiting resistor to the LED chip. A crystal emits light of a predetermined radiation wavelength, which is processed by a conical reflector of the polymer cornea and unfolded by it in the horizon plane. After processing the LED radiation with a cylindrical Fresnel lens, we obtain at the output of the device the necessary light intensity and the necessary radiation angle in the vertical plane.

the proposed semiconductor emitter for circular navigation lights provides the following performance characteristics:

Operating current - 25 ... 60 mA; Operating voltage - 2.5 ... 4 V; Light color: red, yellow, green, white;

Luminous intensity when used in conjunction with a cylindrical Fresnel lens - 1.5 ... 3 cd;

Estimated visibility range - 1.5 ... 3.5 km; Operating temperature range: minus 40 ... + 55 ° С; Service life - at least 30,000 hours.
