Description

Tubular LED lamp for indoor lighting

The invention relates to a tubular LED lamp for interior lighting that can be used for lighting fixtures in cultural-administrative buildings, offices, hotels, schools and home lighting.

A number of types of luminaires are used that use 0.1-0.5 A LED modules, 60-180 pieces, in clear plastic tubes, which can replace the current tubular fluorescent lamps. of 18 W and 36 W respectively and which are interchangeable. The supply of these tubular lamps consists of an electronic system, inserted inside the tube and supplied with a mains voltage of 230 Vac. Through the electronic system of this power supply, the LED modules are powered at a voltage of 24 Vdc. It is mentioned that these tubular LED lamps can be installed in the current luminaires, which provided ballasts and starters for priming and operating the lamps, by removing the starter and the lamp. The new luminaires equipped with such tubular LED lamps no longer use the lamp, ballast and starter from the old luminaires.

It should be noted that LEDs, although known for a long time, thanks to advanced technologies can only now be used in interior lighting.

These systems have the following disadvantages:

- excessive and uncontrollable heating due to the operation of the LEDs;

- when the temperatures of 50 ° C inside the tube are exceeded, the life of the LEDs decreases;

- the electronic power supply for the tubular LED lamps, which is placed inside the tubes, does not have a temperature control system and the operation of the electronic components may be affected;

- high cost price;

- it is not possible to monitor individually a network of luminaires equipped with LED tubular lamps;

- dimming can only be adjusted from zero to the maximum value, only from a value of 20% of the value of the light intensity to the maximum value of the light intensity.
