Description

The invention relates to the field of lighting and laser technology.

Known LED lamp containing a housing with a reflective surface, made in the form of a regular multifaceted pipe made of a dielectric material having a cover in its window wall with a central hole at the open end of the pipe, LEDs communicating through conductors with a lithium unit, screw base [1] . Such a lamp can have high power LEDs with a light-emitting crystal on a ceramic substrate of a rectangular or other shape [2].

The objective of the invention is to expand the range of lamps for light pumping the working fluid of the laser and save electrical energy.

The technical result is achieved by the fact that in the LED lamp, designed to pump the working fluid of the laser, containing a body with a reflective surface, made in the form of a regular multifaceted pipe made of a dielectric material, having a cover in its window wall with a central hole at the open end of the pipe, LEDs communicating through conductors with a power supply, a socle, LEDs, are installed in the windows made in the housing and facing the inside of the pipe, and pumping with a light stream occurs when placed and in the cavity of the lamp of the working fluid of the laser. In the tube, the LEDs are staggered.

In FIG. 1 shows a LED lamp having a housing in the form of a regular hexagonal tube, side view; in FIG. 2 is a view of the hexagonal pipe along AA in FIG. one; in FIG. 3 shows a scan of a hexagonal pipe with the arrangement of the LEDs in a checkerboard pattern (B is the bend line of the faces).

The LED lamp (Fig. 1) contains a screw hollow base 1 with a built-in power supply 2, housing 3, having the form of a regular multi-faceted tube with a reflective surface 4 on its inner side. A pipe made of a dielectric material in the cross section has the shape of a regular polygon, for example a hexagon. The basement from the location of the power supply in it has a transition from a circular cross section to a hexagonal one. At one end, the pipe is fixed to the base. The other end of the pipe is provided with a cap 5 having a central hole 6 (Fig. 2). In the wall 7 of the pipe, round-shaped windows 8 are made for placement in them (facing the inside of the pipe) of LEDs 9 with a light emitting crystal (not shown) on a rectangular rectangular ceramic substrate 10, for example, Luxeon Rebel (Alln CaN) LEDs. Ceramic substrate LEDs are located on the outside of the pipe. The LEDs through the isolated conductors 11 of the electric current communicate with the power supply, and the power supply with the side and central contacts of the base. On the inner side of the pipe, the LEDs can be arranged one against the other or in a checkerboard pattern (Fig. 3). The pipe may be enclosed in a protective removable ventilated casing (not shown).

The manufacturing process of the LED lamp includes the following operations.

1. From a heat-resistant plastic material by casting, a screw base (E 27, пол 14) is made of a hollow base 1 having a transition from a circular cross section to a hexagonal one (Fig. 1). A power supply unit 2 is placed in the basement, comprising a diode bridge, capacitors, and another (not shown).

2. Of the ceramic (porcelain), heat-resistant electrical plastic or other dielectric material by molding method, a body 3 is made that looks like a regular multifaceted pipe with a reflective surface 4 on its inner side. In the wall 7 of the pipe during its formation, the presence of round windows 8 is arranged, for example, arranged in a checkerboard pattern (Fig. 3). A cover 5 with a reflective surface and a central hole 6 is made from the same material (Figs. 1 and 2).

3. Produce (acquire) LEDs 9 having a ceramic substrate 10 with anodes and cathodes, to which are connected (by twisting) the electric current conductors 11. Conductors are laid along the outer wall of the pipe with the formation of a parallel connection of LEDs with a power supply.

4. Assemble the LED lamp: put the body (pipe) on the base; open end of the pipe close the lid. LEDs are installed in windows, ceramic substrates are attached to the wall (faces) of the housing, for example, using glue that can withstand high temperatures.

Connect through the cap 1 with the power supply 2 located in it, the LED lamp to the AC network. LEDs 9, having a ceramic substrate 10 with anodes and cathodes to which electric current conductors 11 are connected, and installed in windows 8 made in a housing 3, having the form of a single facet fixed to a socket multifaceted tube 7, with a reflective surface 4 on the inside , and facing the inside of the pipe, begin to emit streams of light. When the LED working fluid of the laser [3] is placed in the lamp cavity, it is pumped with a light flux with the formation of a monochromatic beam, which exits through the central hole 6 in the cover 5. To ensure safety (from electric shock) and to cool each ceramic substrate, the pipe is placed in a protective removable ventilated casing (not shown).

The range of lamps for light "pumping" of the laser working fluid is expanding, and electrical energy is being saved.
