Description

A kind of LED road lamp shade

Technical field

The utility model relates to LED parts, especially a kind of LED road lamp shade.

Background technology

LED light source is novel energy-conserving light source, general LED light source power being greater than 80W is called high-power LED light source, at present, the development & application of high-power LED light source is gradually ripe, has wide market prospects, but, the high-powered LED lamp utilizing high-power LED light source to make can produce more heat transfer in luminescence process, if heat can not shed in time, can affect the work of components and parts, reduce the operating efficiency of light fixture, reduce its service life.

The radiating fin of high-powered LED lamp on existing market mainly on lamp socket or lampshade dispels the heat, but its volume is comparatively large, and radiating effect is not satisfactory, causes high-powered LED lamp to be heated yielding and aging, and great power LED lamp efficiency is reduced.

Through retrieval, the patent No. is that the patent document of CN200810022209.2 discloses a kind of multi-light source LED road lamp, effectively can reduce the loose amount of installation of street lamp, but complex structure, processing technology is complicated, and production cost is higher, and power is large, is unfavorable for promoteing the wider application.

In view of the foregoing, the radiator structure of existing LED needs to improve.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of LED road lamp shade, can the temperature of effective control LED module, good heat dissipation effect, ensure its service life, integration degree is high, cost is lower, convenient processing and maintenance, fully improves the utilization rate of light, lampshade and substrate can adopt partial installation, good water-proof effect, resistance to oxidation, corrosion-resistant, can Long-Time Service, not fragile.

The utility model to achieve these goals, adopts following technical scheme: a kind of LED road lamp shade, be by: housing, top board, long side plate, short side plate, strip louvre, circular louvre, arc louvre, inverted U-shaped installing port are formed; The top board side of housing arranges circular heat radiation group, at least one group leader's bar shaped louvre is symmetrical arranged between circular heat radiation group and top board one end, the long side plate of housing both sides is arranged at least three group leader's bar shaped louvres, below the short side plate of shell one end, inverted U-shaped installing port is set.

Described top board is cambered surface.

The top of described long side plate be camber line below.

Described circle heat radiation group arranges four groups of transmitted waveform louvres by four circular louvre peripheries and forms, and often organize transmitted waveform louvre and be made up of at least four arc louvres, the arc louvre correspondence of circular heat radiation group arranges formation at least four concentric circles.

Described every group leader's bar shaped louvre is made up of at least two parallel to each other settings of strip louvre.

Strip louvre correspondence on the long side plate in described housing both sides is arranged.

The beneficial effects of the utility model are: the heat that LED light source of the present utility model comes out in the course of the work is outwards shed by louvre, can the temperature of effective control LED module, good heat dissipation effect, ensure its service life, integration degree is high, and cost is lower, and secondary optical design is easy, convenient processing and maintenance, the utilization rate of abundant raising light, lampshade and substrate can adopt partial installation, and adopt waterproofing design, good water-proof effect, resistance to oxidation, corrosion-resistant, be convenient to safeguard, can Long-Time Service, not fragile.

Housing of the present utility model and substrate are all adopted as aluminium alloy heat sink, and radiating effect is remarkable, and area of dissipation is large, good heat dissipation effect, effectively promote LED electrical power module heat dissipation, and simple and compact for structure, and volume is little; Aluminum alloy material has that thermal conductivity is good, thermal resistance is high, rapid heat dissipation, lightweight, price is lower (compared to materials such as copper), the feature of good weatherability (compared to materials such as PC), good heat dissipation effect, can manufacturing cost be reduced, long service life, between adjacent heat radiation assembly, there is gap, heat radiation is corresponding to be arranged, make air form convection current, strengthen radiating effect, inner heat is outwards shed in time, make high-powered LED lamp not easily aging distortion, effectively extend its service life.
