LIGHT SEALED TRANSPORT LAMP

  ; ,:. - Sr;

The present invention relates to light-signaling devices installed on civilian and military automobile, armored and other transport equipment, as well as on trailers to head vehicles for carrying out maneuvers and to maintain a visible 7: linkage when moving vehicles in columns.

Known indicator lamps 1,2, in which a light emitting diode is placed inside the housing with a thread on its outer side. A cap nut is screwed onto the housing from above, tightening the entire structure, inside of which

There are transparent polarizing glasses or lenses, as well as filters that do not pass infrared radiation. On the case are mounted,

nuts for fixing the device to the indicator board. Power wires exit the bottom of the chassis through openings.

The disadvantages of these indicator lamps are connected with the theory that with their help it is impossible to change and redistribute the light flux, since there is no reflector.

In 3, a light-emitting diode in a mandrel is proposed for placement in any device, which is a prototype of the alleged invention. It consisted of a light source placed in a reflector, closed on top with a lens element with a convex external and concave internal surfaces. The LED housing is rigidly seated in a cylindrical tube, on the outer surface of which there is a thread.

The disadvantage of the prototype is not completely sealed and compact design containing a large number of various parts, the strength of which is reduced due to the hollow body ..

&

This goal is achieved by the fact that in a light-signal sealed transport lamp containing a reflector, a light-emitting diode installed in the reflector at the upper base of a heat-conducting metal cylinder with thread on the side surfaces, two cylindrical openings with wires, which are of great value, are connected to them in the reflector, the reflector made in the volume of a metal cylinder at its upper base, equipped with a partition blocking the outlet and pressed against hney union nut to the end openings of the metal gasket uplotnschednuyu tsiliydra through and exiting the metal cylinder lead wires are insulated from the housing and fastened therein by a sealing agent made of, e.g., epoxy resin.

This goal is also achieved by the fact that a hollow transparent cylinder is attached to the end of the rim of the outlet of the reflector, at the end of which an opaque cover with a conical reflector attached to it is sealed.

The set goal can be achieved by the fact that as a partition, overlapping; output hole 01 |) of the applicator, circular transparent plates made of a material selected from the group are used: glass, transparent plastic, transparent filter with circular or linear polarization of light, and also a substance with infrared absorption.

The essence of the alleged invention is illustrated in the figures.

The device shown in figures 1 and 2 consists of a metal cylindrical body (for example, aluminum), at the end of which at its upper base there is a protector 2, in which an LED 3 is placed. There are threads on the outer side surface of the cylindrical body 1, with

with the help of which the whole structure is pulled together into a single monolithic device. The union nut 4 presses through the rubber seal 5 a transparent partition 6 mounted on the end of the outlet of the reflector 2. The radiation 7 of the LED 3 goes into the environment; space through a transparent partition 6, which is used as glass, transparent plastic, a transparent filter with a circular or linear polarization of light, as well as a substance with the absorption of infrared radiation. To install the lamp on the indicator board, use nuts 8 and 13. For the purpose of: 1 i .:: ::: V,. ; To improve heat transfer, LED 3 is tightly mounted on its base to the bottom 9 of the reflector 2. Using a central hole in the lower union nut 10, the current leads And to LED 3, sealed with epoxy resin 12 on the lower base of the metal cylinder 1, are protected from mechanical damage. Fig. 3 shows a longitudinal section of a part of the construction of the transport lamp, where the 14-conical surface of the reflector 15, .. lying on the ledge of a transparent hollow cylinder 16 made of plastic. The top cover 17 is screwed onto a transparent hollow cylinder 16, and in the center of the cover 17 there is an assembly 18 for connecting the reflector 15c to the top cover. When applying DC voltage of 3-5 V to current leads 11, depending on the nominal characteristics of LED 3, the latter starts to shine along the center line of the device. Thanks to the reflector 2, made at the end of the cylindrical body I, the light is focused narrower. As a partition 6, overlapping the outlet of the reflector 2, circular transparent plates made of glass, transparent plastic, a transparent filter with circular or linear polarization of light, as well as a transparent substance with infrared absorption, which can unmask the transport lamp device, are used . To create light distribution in circular geometry, a light-signal transport lamp is used, the lamp shown in Fig.Z. The radiation 6 of the LED 3 goes directly through the transparent cylindrical walls 16 or after reflection from surfaces 2 and 14. This lamp has x // uL - / I- {G.:, -g «- ..- -,

light masking properties, since its radiation: does not propagate in

the protective part of the hemisphere of space.
