RU182519U1 - LED Pendant Luminaire - Google Patents

Abstract

Presented pendant lamp consists of a central tubular part, which houses the terminals, the original mounting to the ceiling, laid electrical wires. Light sources (from 2 to 4) are fastened to the central part through the bracket plate, consisting of two GX53 lamps, two GX53 lampholders fastened together through a bracket plate, and a lampshade.

In the presented LED pendant lamp, GX53 lamps are used in pairs - they shine up and down (left-right), which allows you to illuminate the room as much as possible.

The original ceiling mount, hidden in the tubular central part of the lamp, allowed us to create a new design for pendant lights.

The aluminum parts of the luminaire, combined with through lampshades, cool LED lamps that are critical to operating temperature.

Paired light sources allow you to turn on only lamps shining up. This allows (an additional function) to make the lighting soft (not dazzling and additionally economical).

Simple manufacturing technology allows you to quickly launch this utility model into production.

Description

The utility model relates to lighting engineering, namely to lighting devices with LED lamps and can be used in industrial, office and residential premises.

The level of technology.

LEDs are an effective light source, have low power consumption and high brightness.

The disadvantage of LEDs is their criticality to operating temperature. The increased operating temperature leads to accelerated degradation of the LEDs - the luminous flux (luminosity) generated by the LEDs decreases (article by MV Ryzhkov in the journal "Lighting Engineering" No. 3 of 2010, p. 25). This process is irreversible. Therefore, it is important to create optimal temperature conditions for long-term operation of LEDs in lighting devices.

A lighting device and a support assembly for this device are known (patent EA 019771 B1 dated 2014.06.30), which is the closest analogue of the claimed utility model. In the indicated lighting device, two boards with LEDs are placed on both sides of a flat round radiator and are covered by spherical light-scattering shells. The outer end side of the radiator has a small cooling area, light-scattering shells create unventilated cavities, which adversely affects the operating temperature of the LEDs.

And even at optimal operating temperatures, the LEDs have a slow degradation process. Therefore, LED manufacturers indicate a limited life of 10,000 to 50,000 hours.

It is more expedient in lighting devices to use not built-in LEDs, but LED lamps. Lamps also need to provide reliable heat dissipation, which is implemented in the presented utility model.

Disclosure of the essence of the utility model.

The utility model is characterized by the following set of essential features:

CX53 LED lamps with their own glass light diffusers are installed in lampshades that are well ventilated by ascending air flows (warm air rises up and cold air falls down in any room), and the lamp housing made of aluminum serves as a radiator, which creates the optimum temperature regime for LED lamps. The lamps will burn out less often, and most of them will last the entire period declared by the manufacturer of these lamps.

GX53 LED bulbs have so far been used in recessed and surface-mounted luminaires where it is not possible to create ideal working temperatures.

The presented utility model opens up new possibilities for using GX53 LED lamps in optimal temperature conditions.

Two lampholders for GX53 5 lamps (Fig. 1) are attached to each other by the sides opposite from the lamps through the bracket plate 4 (Fig. 1), forming a paired light source consisting of two GX53 5 lamps (Fig. 1), which shine in opposite directions side up and down (left and right).

The bracket plate 4 (Fig. 1) is attached to the lampshade 2 (Fig. 1) and the central tubular part 1 (Fig. 1), forming a large area radiator for cooling LED lamps.

Lampshades cover the lampholders of the GX53 and the light-emitting part of the lamp housing. The minimum lampshade width and the light-scattering lamp shells are not covered by lampshades. Through lampshades 2 (Fig. 1) allow you to effectively cool the lamp with ascending air currents.

In the central tubular part 1 (Fig. 1), the terminals, the original mount to the ceiling, wires are laid. A decorative plate 10 is laid between the central part and the ceiling (Fig. 1) to close the thermo-ring of the stretch ceiling or to close the defects in the release of wires of the lighting network from the concrete ceiling. U-shaped plate 3 is fixed at the top of the central part inside (Fig. 1). A screw-hook 7 (Fig. 1) passes through a hole in this plate with a nut 8 (Fig. 1) at the end. The lamp is suspended from the ceiling. The terminals connect electrical wires. Terminals and wires are laid inside the central part. Rotating the nut 8 (Fig. 1) on the screw-hook 7 (Fig. 1) with a pipe wrench 11 (Fig. 1), the lamp is attracted to the ceiling. From below, the central part is closed with a plug.

Paired light sources, consisting of two CX53 lamps, allow you to turn on the lamps one at a time. If you turn on the upper lamps, the lighting can be made soft (not dazzling), which is important when working on a computer and when watching TV (there are no light flares).

The round and flat lamp GX53 is the most promising for organizing heat removal and allows you to make the lamp very compact, which is important for small rooms.
