Abstract

The utility model relates to the technologies of lighting, LED (light-emitting diode) light source, and radiation as well as the technical field of lamps and lanterns. The LED underground project lamp includes an underground tube, a lamp tube, a lamp board, a lens component, a LED core, a printed board, a low-voltage constant-current power, a transmitting glass, a cover, a metal waterproof joint, etc. The LED underground project lamp can be divided into three major parts. The lamp board, the lens component, the printed board, and a lampshade form a base component. The LED underground project lamp with square outside and round inside has a novel structure, which breaks through the characteristics that the traditional project lamp has a round appearance, the central line of a lighting corner is vertical to the glaring surfaces of the lamps and lanterns and the lamps and lanterns are arranged on the ground; secondly, the LED underground project lamp has a plurality of colors, and adopts the fourth generation novel light source-LED light source which saves energies and protects the environment.

Description

A kind of LED buries the ground Projecting Lamp

Affiliated technical field

The utility model relates to a kind of public lighting device, especially a kind ofly is embedded in underground and uses the Projecting Lamp of LED (light emitting diode) spot light.

Background technology

The utility model adopts new type light source---LED spot light, energy-saving and environmental protection; The light fixture water proofing property is good, and cost is moderate, is a kind of public lighting device.

Summary of the invention

The purpose of this utility model provides a kind of public lighting device underground and use LED spot light that is embedded in.And this utility model has energy-saving and environmental protection, the life-span is long, cost is moderate characteristics.

The utility model is divided into three big major parts, and lamp plate, lens subassembly, LED wick, printed board, lampshade have been formed part lamp plate assembly; Lamp tube, low pressure constant-current supply and lamp plate assembly have constituted the lamp cartridge module; Bury ground tube and water joint and formed base member.

The utility model has the advantages that and to adjust lighting angle according to the height of shone thing, fully illuminate shone thing, possess the advantage of underground lamp and Projecting Lamp.Secondly, energy-saving and environmental protection, the life-span is long, cost is moderate, and color can be provided with arbitrarily, but city taste is improved in the beautifying city.

The specific embodiment

As shown in Figure 1, the utility model comprises 11 main components, it is characterized in that 3 lamp plate assemblies are installed in the aluminium matter lamp tube, and 3 1wLED wicks and lens are housed on each lamp plate, is stamped the thick stainless steel lid of thick safety glass of 10mm and 5mm above the light fixture.

Advantage of the present utility model is mainly reflected in following three aspects:

The structural design aspect: 1. bury a ground tube profile and be square-outside and round-inside and form a cavity, the lamp tube is rounded, and both match, and can realize on the horizontal plane 360 ° rotation; 2. lamp plate assembly wick position and horizontal plane are angled, and aluminum alloy material is convenient to regulate according to actual needs lighting angle.3.LED spot light is connected on the low pressure constant-current supply, the low pressure constant-current supply is fixed on the lamp tube, and whole being contained in buried in the ground tube, and be very safe.4. be stamped the thick stainless steel lid of thick safety glass of 10mm and 5mm above the light fixture, increased the intensity of light fixture, passerby's walking, child tramples, the also safety of playing; 5. use the acrylonitrile-butadiene rubber collision mat between lamp tube and the transparent glass, lid is with to bury ground tube fastening with 8 sunk screws, and smear 705 glue and seals at the place, slit, and these measures all can effectively improve the degree of protection of light fixture.The maximum characteristics of this structure are the advantages that combine underground lamp and Projecting Lamp, have enlarged its field of employment.

The optical design aspect: light source adopt the 4th generation new type light source-led light source, it be a kind of be the cold light source of illuminator with the light emitting diode, pollution-free, light efficiency reaches more than the 80Lm/W.In order to make the even and minimizing dazzle of the final bright dipping of light fixture, scheme has adopted lens subassembly, and light is through the lens secondary distribution.The design of lamp cylinder size has guaranteed that 120 ° of luminous angles of LED wick are unaffected.In a word, the high power light source of 9 1W disperses to distribute, and has improved the uniformity of illuminance on the working face.

The thermal design aspect: 1. wick closely contacts with aluminium matter lamp plate by conducting strip, printed board, guarantees that heat leads away fast.2. the lamp tube also is that Birmasil is made with burying the ground tube, and radiating effect exceeds tens times than traditional iron sheet.3. the light emitting source wick disperses to distribute, and apart from each other helps heat radiation each other.Above-mentioned cooling measure makes light fixture long-life characteristics that assurance arranged.

Claims

1. a LED buries the ground Projecting Lamp, it is characterized in that: by bury ground tube, lamp tube, lamp plate assembly, low pressure constant-current supply, the thick stainless steel lid of safety glass, 5mm that 10mm is thick is formed.

2. LED according to claim 1 buries the ground Projecting Lamp, it is characterized in that: profile is square-outside and round-inside and forms a cavity, and the lamp tube is rounded, and both match, and can realize on the horizontal plane 360 ° rotation; Secondly, lamp plate assembly wick position and horizontal plane are angled.

3. LED according to claim 1 buries the ground Projecting Lamp, and it is characterized in that: wick closely contacts with aluminium matter lamp plate by conducting strip, printed board; Lamp tube and bury ground tube and adopt a Birmasil to make; The light emitting source wick disperses to distribute.
