Description

A kind of LED street lamp that adopts the heat pipe heat radiation technology

Technical field

The utility model belongs to LED illumination and heat radiation field, refers to adopt the LED lighting of heat pipe heat radiation technology especially.

Background technology

The general power of LED street lamp is bigger, and caloric value is very high, causes street lamp internal work temperature overheating, makes led chip and driving power be easy to generate fault.The LED street lamp heat radiator generally adopts the aluminium fin structure at present, and radiating efficiency is low.If use heat-pipe radiator instead then radiating efficiency can improve greatly, heat pipe heat radiation efficient can be higher than tens times in entity aluminium to hundreds of times, but the combination of many small-power luminescence chips is adopted in existing LED road-light light-source design, heat generating spot relatively disperses, cause the evaporation cavity part of heat pipe can't concentrate the collection heat, simultaneously, existing lamp post structure is because the inner space is narrow and small, flat, make heat pipe lack putting position, cause the area of dissipation deficiency, heat-sinking capability is low, and therefore, hot pipe technique is seldom adopted in existing LED street lamp design.

Summary of the invention

The purpose of this utility model is to provide a kind of high-power LED street lamp with high efficiency and heat radiation ability.

Overall technology design of the present utility model is:

The light source design of existing LED street lamp adopts the integrated mode of polylith small-power luminescence chip, the utility model light source then adopts the high-power light-emitting chip, for example 120W LED street lamp generally has the luminescence chip of 4 30W to make up at present, and be evenly distributed on lamp surface, can change into and adopt 2 60W luminescence chip combinations, and led chip is concentrated the middle lower curtate position of fixedly putting in light fixture, connect by installing plate, the evaporation cavity of led chip and heat-pipe radiator (heat pipe heat radiation pipeline and box-like evaporation cavity are combined into heat-pipe radiator) fits tightly, the position, middle and upper part of light fixture is used for fixedly putting the heat pipe heat radiation pipeline, to form the gravity circulation.For strengthening luminous power, also can be with two cover heat-pipe radiators in the vertical unit combination in same plane.The box-like evaporation cavity position of every cover heat-pipe radiator is furnished with corresponding led chip.

Concrete measure of the present utility model also has:

It is raw material that the box-like evaporation cavity of heat pipe adopts aluminium, utilizes mould to be extruded into square tube, uses metal end shutoff two ends again.Owing to extrude aluminium section bar length and can adjust, so, to can make the box-like evaporation cavity that floor space varies in size after the aluminium section bar two ends shutoff of extruding, so just can make box-like evaporation cavity bottom surface cover one or more led chip as far as possible, the heat of LED luminescence chip can be concentrated import to box-like evaporation cavity, to improve radiating efficiency.

Simultaneously, the heat pipe heat radiation pipeline is communicated with box-like evaporation cavity, box-like evaporation cavity forms two parallel aspects up and down with the heat pipe heat radiation pipeline, the centre has pipeline to connect, box-like evaporation cavity is positioned at subsurface, the heat pipe heat radiation pipeline is positioned at aspect, and both form potential difference up and down, to promote better gas-liquid gravity circulating effect.

Heat pipe heat radiation pipeline and box-like evaporation cavity all are fixed in the front of the installing plate of light fixture, and led chip and lens all are fixed in the reverse side of installing plate, and installing plate and lampshade are connected and fixed with screw or other method, and be dismantled and assembled.

The substantive distinguishing features that the utility model is obtained and remarkable technological progress are:

1, utilize hot pipe technique to solve the heat dissipation problem of high-power LED street lamp, under good radiating condition, the working life of led chip will be doubled and redoubled.

2, light source adopts high-power LED chip, and fits tightly with the box-like evaporation cavity of heat pipe, chip heat can be concentrated import box-like evaporation cavity, forms the perfect adaptation of led chip radiating requirements and hot pipe technique design feature.

3, for guaranteeing the working medium gravity circulating effect of heat pipe, improve the heat pipe heat radiation ability greatly, light source has adopted and has been fixed in lower curtate position in the light fixture, the employing of heat-pipe radiator heat pipe heat radiation pipeline and two parallel aspects about box-like evaporation cavity lays respectively at.

4, box-like evaporation cavity adopts the preparation method who extrudes aluminium section bar, not only is beneficial to industrialized mass production, and has solved the comprehensive applying problem of box-like evaporation cavity and led chip.
