Description
Technical field
The utility model relates to LED lamp field, is specially a kind of LED street lamp illuminating module.
Background technology
The LED lamp is a kind of light emitting semiconductor device commonly used, has advantages of energy-conserving and environment-protective.Prior art LED street lamp module generally is comprised of heat spreader module, aluminum-based circuit board, lamp pearl, PC lens cap, protecting glass etc.In prior art LED street lamp module, chip institute is luminous passes through silica gel cup or seep through cup optically focused after fluorescence silica gel excites, then penetrates by protecting glass through lens reflection leaded light orientation, and light needs through 4 roads refraction reflections, and light loss is larger.In prior art LED street lamp module, heat reaches Lamp cup pedestal and both positive and negative polarity pin by chip bottom simultaneously, reach again pad on wiring board, reach aluminium base through the insulation coating, reach the radiation aluminium module by the aluminium base heat-conducting glue, through the heat conduction of four layers of tactile face medium thermal resistance, heat-conducting area is little, and contact-making surface driving fit fully, and thermal resistance further strengthens, the heat conduction path is not smooth, radiating module efficient is not high, causes the module volume large, and cost is high.Heat conduction is not smooth also can cause junction temperature of chip higher simultaneously, has a strong impact on chip light emitting efficient and life-span.
The utility model content
The purpose of this utility model is to provide a kind of LED street lamp illuminating module, and is large to solve prior art LED street lamp light loss, the problem that heat dispersion is poor.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of LED street lamp illuminating module includes fin, it is characterized in that: fin surface has a plurality of bar shaped light troughs, each strip light trench bottom has mounting groove, lamp pearl module is arranged in mounting groove and closely and matches, and is sprayed with the nanometer material in lens carrier, is arranged in the bar shaped light trough.Lens are installed in lens carrier, and lens are glass lens or PC lens, and filling with in the bar shaped light trough between lens carrier and lens carrier has fluid sealant and higher than lamp pearl light-emitting area.Have vertical slot on the fin at lamp pearl module two ends, fixing circuit board and closely matching in vertical slot, wiring board is connected by circuit with lamp pearl module, the formation current supply circuit.
Described a kind of LED street lamp illuminating module is characterized in that: described lamp pearl module is arranged in mounting groove in fin and closely matches.
Described a kind of LED street lamp illuminating module is characterized in that: poured into high temperature resistant aging-resistant marine glue in described vertical slot.
Described a kind of LED street lamp illuminating module is characterized in that: be connected with a plurality of forked ennations bottom described fin.
Described a kind of LED street lamp illuminating module is characterized in that: described light trough is ranks distribution anyhow in fin surface.
The utility model need not the adapted aluminum-based circuit board, lamp pearl module is directly fixed in fin, lens carrier directly contacts with fin, hinder the heat conduction without any sprayed on material between contact-making surface, filling is with the thermostable heat-conductive sealant sealing, when possessing waterproof, sealing, heat conduction, safe function, lamp pearl contact area of dissipation is increased to more than 3 times of ordinary lamps pearl, junction temperature falls on a year-on-year basis more than 30%.Be equipped with simultaneously the lens carrier that nanometer technology makes; and glass lens or PC lens; not only light loss reduces 3%-5%; can also further improve reflecting effect; effectively reduce dazzle; illumination strengthens and uniformity improves, and lens carrier and lens are when playing the seal protection effect to the lamp pearl, and lens carrier and lens can directly contact with external environment condition.The utlity model has radiating effect and illumination effect preferably.

The specific embodiment
As Figure 1-Figure 4.A kind of LED street lamp illuminating module, include fin 1, fin 1 surface has a plurality of bar shaped light troughs 2, the mounting groove 3 that each bar shaped light trough 2 bottoms have, lamp pearl module 4 is arranged in less mounting groove 3 and closely matches, be sprayed with the nanometer material in lens carrier 5, be arranged in bar shaped light trough 2.Lens 6 are installed in lens carrier 5, and lens 6 are glass lens or PC lens, and filling with in the bar shaped light trough 2 between lens carrier 5 and lens carrier 5 has fluid sealant and a little more than lamp pearl light-emitting area.Have vertical slot 7 on the fin 1 at lamp pearl module two ends, the interior fixing circuit board 8 of vertical slot 7 and closely matching, wiring board 8 is connected by circuit with lamp pearl module 4, forms current supply circuit.
Lens 6 are glass lens or PC lens.
Poured into high temperature resistant waterproof glue in vertical slot 7.
Fin 1 bottom is connected with a plurality of forked ennations 9.
Light trough 2 is anyhow, and ranks distribute at fin 1 top.
The utility model has a plurality of bar shaped light troughs in fin surface, and each strip light trench bottom has less mounting groove, and lamp pearl module is arranged in less mounting groove and closely matches, and is sprayed with the nanometer material in lens carrier, is arranged in the bar shaped light trough.Lens are installed in lens carrier, and lens are glass lens or PC lens, and filling with in the bar shaped light trough between lens carrier and lens carrier has fluid sealant a little more than lamp pearl light-emitting area, with fixed light pearl support and printed circuit board, strengthen heat radiation and water proof and dust proof.Have vertical slot on the fin at lamp pearl module two ends, fixing circuit board and closely matching in vertical slot, wiring board is connected by circuit with lamp pearl module, forms current supply circuit, but while external power supply output line.Poured into high temperature resistant waterproof glue in vertical slot, but the protection circuit plate.
