LED lamp strip

Abstract

The invention discloses a LED light bar which is composed of a LED single lamp, a circuit board, an aluminium groove, a protective glue, a heat-conducting medium, a side plug, a connector and a driving power supply, wherein the cross section of the aluminium groove is in a shape like the Chinese character 'ao', the inner side of the aluminium groove is provided with two steps with two boss parts arranged thereon, the circuit board is arranged on the steps and below the boss parts of the aluminium groove, the heat-conducting medium is arranged in the aluminium groove, a tubular LED light bar is formed between the circuit board and the aluminium groove, two ends of the LED light bar is plugged by the side plug, in which a connecting wire is packed in the center of the side plug when injection molding on one end of the LED light bar, the tail end of the connecting wire is a waterproof connector which is used for connecting between the LED light bars. The LED light bar of the invention has the advantage of long service life, energy saving, uniform light distribution and easy installation.

Description

technical field [0001] The present invention relates to a new light source, more particularly, to an LED light bar. Background technique [0002] At present, there are not many lighting sources that can be used in small spaces, mainly T5 fluorescent tubes and PVC hose lights (also called neon hoses or Meina lamps, English name (Rope Light)). Generally speaking, small spaces such as advertising light boxes, ceiling dark grids, window cabinets, and stair steps do not have high requirements on the brightness of the lighting source, but the requirements for firmness, safety and life are very high. It is difficult to install and do not want to change the lamp or maintain it frequently; secondly, the volume of the lighting source is required to be small, for example, the diameter of the T5 fluorescent tube is 15mm, and the diameter of the PVC hose lamp is as small as 13mm. [0003] The advantage of T5 fluorescent tube is high brightness, but the disadvantage is that it is fragile...

AI Technical Summary

Problems solved by technology

[0003] The advantage of the T5 fluorescent tube is high brightness, but the disadvantage is that it is fragile, unsafe and has a short lifespan. The T5 fluorescent tube is fragile, and once it is broken, the mercury vapor in the tube will come out. Mercury is highly toxic and extremely harmful to the human body. It is large and can cause cancer; in addition, T5 fluorescent tubes are driven by high voltage, which is not safe, and their lifespan is less than 5,000 hours, so they need to be replaced every year

[0004] PVC hose lights originally used small neon lamps (neon-filled tungsten lamps) with extremely low luminous efficiency, and consumed 20W per meter. Since 3 years ago, the light source of PVC hose lights has gradually changed to LED single lights, saving energy. Electric, the structure is strong, but there are many disadvantages, including low brightness and uneven light distribution

The reason for the low brightness is that the LED single lamp is wrapped in 2 layers of PVC with poor light transmission, and more than half of the light emitted by the LED is lost through the PVC.

In addition, for white LED PVC hose lights, because the single LED lamp is sealed in PVC material with poor heat dissipation, the temperature of the white LED chip is so high that the LED light decays quickly and the life span is less than 3000 hours.
