Abstract

The utility model discloses a novel LED streetlamp module device which comprises a heat radiating body, a fixed structural part, a self-tapping screw and an aluminum substrate jointed with the bottom surface of the heat radiating body, and an LED light source fixed on the aluminum substrate. The novel LED streetlamp module device is characterized in that a PC (Poly Carbonate) lens for secondary light distribution is covered on the LED light source, a sealing rubber strip is arranged between the PC lens and the aluminum substrate, and the heat radiating body is formed by aluminum material through drawing. According to the LED streetlamp module device, the LED light source, the corresponding heat radiating body, the aluminum substrate, the PC lens and the sealing strip are assembled into the streetlamp module by the structural fastener and the screw, LED streetlamps with different casing shapes can be assembled, in maintenance, only the faulted modules need to be dismantled, the operation of other modules cannot be affected, namely the whole streetlamp can be continuously used.

Description

A kind of Novel LED street lamp modular device

Technical field

The utility model belongs to the high-power LED street lamp technical field, relates to the chief component light emitting module in a kind of high-power LED street lamp, relates in particular to a kind of Novel LED street lamp modular device.

Background technology

For high-power LED street lamp, the quality of heat abstractor can directly influence its service life, and solution heat dissipation problem as much as possible could prolong the street lamp life-span, reaches energy-conservation effect, could guarantee the superiority of product; The effect of optics luminous intensity distribution directly influences the practical effect of street lamp, and good luminous intensity distribution design could guarantee irradiated area and uniformity of illuminance; The reasonable structural design aesthetics that can improve street lamp can promote the application of street lamp again in addition; In the high-power LED street lamp that exists on the market now; Their mode mostly is to adopt integral Al-alloy stretching street lamp body; All light sources and electrical equipment are arranged on the heat radiator body, and pattern is single, cannot conversion; The light source damage of one place needs the whole light fixture of dismounting, and maintenance is extremely inconvenient.

Summary of the invention

The purpose of the utility model is the technical problem that solves the prior art inconvenient maintenance, a kind of Novel LED street lamp modular device is provided, to overcome the deficiency of prior art.

To achieve these goals; The utility model LED street lamp modular device; The aluminium base that it comprises radiator, fixed structure piece, tapping screw, fit with the radiator bottom surface and be fixed on the led light source on the aluminium base; It is characterized in that said led light source above be coated with the PC lens of secondary light-distribution effect, be provided with sealing joint strip between said PC lens and the aluminium base, said radiator is by the aluminium drawing and forming.

Said led light source is made up of 12 LED lamp pearls.

The utility model is by led light source and corresponding radiator, aluminium base, PC lens and sealing joint strip; Form a street lamp module through structural fasteners and screw; Can be used for assembling the LED street lamp of different profile lamp housings; Only need dismantle bad module during maintenance and get final product, the promptly whole small cup of the use street lamp that does not influence other modules still can continue to use.

The specific embodiment

Referring to figs. 1 through Fig. 4; The utility model LED street lamp modular device; The aluminium base 4 that it comprises radiator 1, fixed structure piece 2, tapping screw 3, fit with radiator 1 bottom surface and be fixed on the led light source 5 on the aluminium base 4; Be coated with the PC lens 6 of secondary light-distribution effect above the said led light source 5, be provided with sealing joint strip 7 between said PC lens 6 and the aluminium base 4, said radiator 1 is by the aluminium drawing and forming; Said led light source is made up of 12 LED lamp pearls.

The led light source 5 of the utility model is to be weldingly fixed on the aluminium base 4 through Reflow Soldering; Sealing joint strip 7 has the water-tight effect; Each parts of the utility model are fixedly connected with tapping screw 3 through fixed structure piece 2, form simple and compact for structure, can be single or the light source module structure of a plurality of independent assortments.

Used radiator is that aluminium matter alloy material forms through Mould Machining in the utility model; The thermal conductivity factor of this material is up to 237W/m ℃; Be beneficial to heat conduction, the convection current of air has been strengthened in the space behind the composition street lamp between its module and the module, has increased the frequency of heat exchange; More can strengthen cross-ventilation if cooperate the outer STH of lampshade; The heat in lamp interior space is exchanged with outside air faster, and its unique modular structure can then be assembled together with different lamp housings through connector a plurality of and together, forms the LED street lamp.

The utility model compared with prior art has outstanding substantive distinguishing features and obvious improvement, and its implementation result also is conspicuous.Both help alleviating the weight of LED street lamp, and can increase the pattern and the aesthetics of LED street lamp again.

Claims

1. Novel LED street lamp modular device; The aluminium base that it comprises radiator, fixed structure piece, tapping screw, fit with the radiator bottom surface and be fixed on the led light source on the aluminium base; It is characterized in that said led light source above be coated with the PC lens of secondary light-distribution effect; Be provided with sealing joint strip between said PC lens and the aluminium base, said radiator is by the aluminium drawing and forming.
