Description

A kind of light emitting diode high brightness waterproof guard rail lamp

Technical field

The utility model relates to a kind of illumination and decorative lamp, and particularly a kind of employing light emitting diode (LED) is the safe and reliable high brightness guard rail lamp that can use out of doors of light source.

Background technology

Market has occurred with the light fixture of light emitting diode (LED) as light source in recent years, comprise can using out of doors and decorate and illuminating tubulose guard rail lamp as road and bridge guiding, building profile, architectural coating, that this light fixture has is energy-efficient, color abundant, control flexibly, the characteristics of long service life.

But the LED guard rail lamp on the market is installed in LED on the circuit board mostly, and circuit board is directly installed on the guardrail pipe, and the outside seal of guardrail pipe constituted, as State Intellectual Property Office's patent No. is as described in the CN2004200428930.8 patent, because LED and circuit board are operated in totally sealed environment, can not efficiently radiates heat during its work, so its power is limited, brightness is not high; Because circuit board is directly installed in the guardrail pipe, and when inefficacy of the guardrail seal of tube or accidental damage, circuit board is subjected to the influence of water logging or aggressive atmosphere easily and is damaged, reliability of products can not get ensureing in addition; In addition, because guardrail Guan Weidan props up sealing, when using, it lacks whole structure.In addition, because board area is big, make its complex manufacturing technology, the manufacturing cost height is safeguarded inconvenience.

Summary of the invention

A kind of light emitting diode (LED) high brightness waterproof guard rail lamp, comprise a plurality of high brightness luminescents unit, heat conduction installing plate, guardrail pipe, it is characterized in that described high brightness luminescent unit is to be encapsulated into one by a plurality of light emitting diodes and constant-current circuit, circuit substrate and heat radiating metal shell to constitute.According to the structure of metal shell, the shape of the luminescence unit that assembles can be circle, and is square and polygonal.

The problem that the utility model solves is, adopted the high brightness luminescent unit of forming by light emitting diode as light source, earlier light emitting diode, constant-current circuit and circuit board are packaged in the metal shell with waterproof and sealing material, make the high brightness luminescent unit with waterproof sealing performance of high brightness, metal shell is simultaneously as radiator structure.Described light emitting diode can be optically focused or non-light-focusing type, can be white, also can be red, green, blueness, yellow or secondary colour.

The utility model is owing to adopted the waterproof sealing unit as basic luminous units, the circuit board and other element that damaged by water logging are used by the unit sealing, on the unit, solved waterproof problem, when installing and using, can cooperate the electrical connector of waterproof to use, do not need again the guardrail pipe to be carried out strict waterproof sealing and handle,, can improve radiating effect greatly so can use guardrail pipe with Open architecture, increase power density, thereby produce the high-power LED guard rail lamp.

Above-mentioned light emitting diode (LED) high brightness waterproof guard rail lamp, its feature also is also have a heat dissipation metal installing plate at least, it is shaped as strip, described high brightness luminescent unit is fixedly mounted on the installing plate, and with its maintenance thermo-contact.Described metal installing plate is a strip, can adopt the material manufacturings such as copper, aluminium of good heat conductivity, also can adopt and carry out material manufacturings such as the steel plate that surfacecti proteon is handled, corrosion resistant plate.Its radiator portion surface can be flat surfaces, also can be the convex-concave surface that helps dispelling the heat.

A plurality of above-mentioned luminescence units distribute on the metal installing plate that is fixed in order, its metal shell closely contacts with the metal installing plate, modes such as fixing means can be with binding agent, be threaded, crimping, its contact-making surface can be strengthened radiating effect with thermal conducting agents such as silica gel or silicone grease, and presses application requirements whole or grouping and tie.

Described high brightness waterproof guard rail lamp also comprises the guardrail pipe, and its feature is that also described guardrail pipe fundamental section is the continuous curve of sealing, can be open curve also, can cooperate with the base of other pattern and forms complete cross-section.

Described high brightness waterproof guard rail lamp guardrail pipe, its feature is that also the bottom of described guardrail pipe has louvre, louvre can be the shapes of various convenient processing such as round, strip.

Described high brightness waterproof guard rail lamp guardrail pipe, its feature also is to have the mounting groove of installing plate, and the position of mounting groove is positioned near the middle part of guardrail pipe cross section, and well width is identical with the width of metal installing plate in it, can cooperate installation.

What described high brightness waterproof guard rail lamp guardrail pipe, its feature also were the guardrail pipe is transparent, also can be for translucent.When using transparent pipe, light output is high, uses when being adapted at throwing light on.When using translucent tube, can make light softer, eliminate dazzle fully, visible angle increases.

With aforementioned assemble luminescence unit installing plate push along the mounting groove in the guardrail pipe, install wiring from the two ends of guardrail pipe, and draw from two ends.Owing to used the metal installing plate, its intensity cooperates protecting of overlength to block pipe far above common copper-clad plate, and its length can reach the several times of common guard rail lamp, changes the decorative effect that loose greatly.

Described high brightness waterproof guard rail lamp, its feature are that also its two ends can have the encapsulation plug, its role is to prevent that dust, foreign material, insect from entering the space of light-emitting area front and influencing light output.

Described high brightness waterproof guard rail lamp, its feature also are to use a plurality of connections of connector to use, and connector can be straight type, also can be the angle type, also can adopt connector that the guardrail pipe is connected piecemeal when installing and using, can accomplish seamless link, its length can prolong arbitrarily.

Described high brightness waterproof guard rail lamp, its feature are that also described luminescence unit can be monochrome, also can be multiple color.The luminescence unit of each color can be united driving, also can distinguish separately to drive.
