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 ye

Embodiment 1

[0042] Example 1: Application of LED light bar in advertising light box

[0043] like figure 1 , figure 2 , image 3 , Image 6 As shown, an aluminum alloy light box with a height of 1.5 meters, a width of 3.0 meters and a thickness of 7 cm is selected to install the LED light bar of the present invention. The LED light bar 13 is fixed in the light box housing 18 by the light bar fixing seat 19 , and the LED light bar is connected by the waterproof connector 11 . The aluminum groove 7 selected in this embodiment is 1440 mm long; the circuit board PCB5 is 15 mm wide, which is just stuck in the groove of the aluminum groove 7 . A large-angle LED single lamp 1 is welded on the circuit board PCB5, and the LED luminous flux is more than 4lm. There are 6 single LED lights on each PCB, all of them are connected in series and limited by 240Ω resistors. A linear LED light bar has 6 PCBs, a total of 36 LED single lights, and the LED single light spacing is 4cm.

Embodiment 2

[0045] Example 2: Application of LED light strips in the dark grid of the ceiling

[0046] like image 3 , Figure 4 , Figure 5 As shown, the LED light bar 13 is fixed in the decorative dark groove 12 by the LED light bar mounting seat 16, the LED light bar 13 has a lampshade 15 outside, and the LED light bar 13 is installed on the side of the wall 17, in order to avoid looking on the ceiling 14 To the light spot of the LED single lamp, a plexiglass frosted lampshade 15 sets of linear LED light strips 13 are used. After the linear LED light bar 13 is lit, the light in the entire dark compartment is soft and comfortable. Generally, the power consumption of a 1-meter T5 fluorescent tube is 28W, and the luminous flux is as high as 2000lm. If it is placed in the dark grid, because the light-emitting angle cannot be controlled, more than 90% of the light is wasted, and only 200lm of light is working. Using a 1-meter linear LED strip, the power consumption is only 4W, the lumin...

Embodiment 3

[0047] Example 3: Window Lighting

[0048] Place a 1-meter-long 7W linear LED strip in a cosmetic window with a width of 40cm and a length of 120cm, and the cosmetic samples in the entire window will be illuminated. Because the light emitted by the LED does not contain ultraviolet and infrared rays, cosmetics will not deteriorate due to the temperature increase caused by infrared rays, and the exquisite packaging of cosmetics will not be discolored or old due to the irradiation of ultraviolet rays.

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...
