Description

A kind of heat radiating device of road lamp
Technical field
The utility model relates to a kind of heat radiating device of road lamp.
Background technology
As everyone knows, LED is high energy efficiency light source, and because length of energy-conservation life-span is very popular.Although LED photoelectric conversion rate high-temperature is lower, compared with the operating temperature of incandescent light source up to 2500 DEG C, LED light source temperature is much lower.But LED is still unable to escape the problems of generating heat and bringing all the time, therefore, many designers recognize that when designing research and development LED lamp heat radiation is a very important problem.Although LED still can generate heat, its temperature is relatively lower, and therefore what large problem this does not have.But, its operating temperature of based semiconductor device LED should lower than 100 DEG C.According to law of conservation of energy, heat (energy) must be sent near zone.LED can only be operated between 25 DEG C of environment temperatures and the highest 100 DEG C, and temperature range is only 75 DEG C.Therefore, the heat-delivery surface that needs one are larger and very effective heat management; The heat abstractor of LED street lamp traditional at present, its thermal component is one block of heat sink, and effective area of dissipation is less, easily causes thermal accumlation too much; The light source radiating device also had is all absorb heat of light source by fin, utilizes shell mechanism to make air form convection current, thus carries out heat conduction.Although this mode uses simple, due to cross-ventilated needs, shell must have larger volume, this results in the increase of cost; And heat-conducting effect depends on cross-ventilated effect, and cross-ventilated effect depends on the design of shell, result in the poor efficiency of the complicated of production technology and radiating effect.The bad light source life of heat radiation is short, and maintenance cost is high thus make LED street lamp there are the serious quality problems of light decay.The shell of fin and street lamp is integrated simultaneously, all makes troubles when transporting and install, simultaneously comparatively large because being integrated weight ratio, easily occurs potential safety hazard in the process of installation.
Utility model content
For solving the problem, it is simple that the utility model provides a kind of structure, good heat dissipation effect, reduces the heat radiating device of road lamp installing hidden danger.
For achieving the above object, by the following technical solutions, a kind of heat radiating device of road lamp, comprises shell to the utility model, the top of described shell offers perforate, be provided with aperture side orthogonal conducting strip in this perforate, the below of described conducting strip is provided with even backing, and this even backing and conducting strip are close to, the both sides of described perforate are provided with guide block, this guide block and conducting strip form guide groove, are inserted with fin in described guide groove, and described fin and conducting strip are close to.
The middle part of described conducting strip is provided with baffle plate, and described fin is two, is located at the left and right sides of baffle plate respectively.
Described fin is fixedly connected with by screw with between conducting strip.
Described baffle plate and conducting strip are integrated, and are made up of brass H68.
Described fin is made up of the fin of base plate and vertical base plate, and the thickness of base plate is identical with the height of guide groove.
Described fin is made up of 1060 aluminium strips.
The utility model adopts technique scheme, has a little following: 1, structure is simple, good heat dissipation effect; 2, housing is separated with fin, only needs fin to be inserted in guide groove when installation, installs simple, and solves housing and fin one, and weight ratio strengthens, and increases cost of transportation, because of the problem of the potential safety hazard of the larger generation of weight ratio during installation.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is a kind of heat radiating device of road lamp structural representation.
1, LED; 2, shell; 3, even backing; 4, fin; 5, guide block; 6, conducting strip; 7, baffle plate; 8, screw; 9, perforate.
Detailed description of the invention
Further a kind of heat radiating device of road lamp is described in detail below in conjunction with drawings and Examples.
A kind of heat radiating device of road lamp as described in Figure 1, comprise shell 2, the top of described shell 2 offers perforate 9, be provided with conducting strip 6 orthogonal with perforate 9 side in this perforate 9, the below of described conducting strip 6 is provided with even backing 3, and this even backing 3 is close to conducting strip 6, the both sides of described perforate 9 are provided with guide block 5, this guide block 5 forms guide groove with conducting strip 6, is inserted with fin 4 in described guide groove, and described fin 4 is close to conducting strip 6, in street lamp installation process, after street lamp installs, fin 4 is being tucked in the guide groove that perforate 9 both sides guide block and conducting strip 6 formed, fin 4 and conducting strip are tightly affixed, reach even backing 3, conducting strip 6 and fin 6 are integrated, realize the heat radiation to street lamp, in work be, LED 1 work time give out heat, (even backing 3 is aluminium to even backing 3, the heat-conducting mediums such as copper are made) absorb the heat that gives out of LED 1, and pass to conducting strip 6, conducting strip 6 sends fin 4 to the heat obtained from even backing 3, fin 4 falls apart received heat in the air in the external world, can find out, the utility model shell 1 be separated with fin 4, transport process in, convenient transport, reduces the cost of transport, when mounted simultaneously, potential safety hazard can not be produced to installation personnel, because weight is excessive in the situation that installation process China collapses because the weight of one is excessive.
In the above-described embodiments, more convenient in order to install, in installation process, exert oneself can not be excessive for installation personnel, the middle part of described conducting strip 6 is provided with baffle plate 7, described fin 4 is two, is located at the left and right sides of baffle plate 10 respectively, can be inserted in guide groove one by one in installation process, alleviate the weight of once mounting like this, for installation personnel alleviates the burden of installation.
In the above-described embodiments, in order to fin 4 be combined with conducting strip 6 tightr, therefore described fin 4 is made up of the fin of base plate and vertical base plate, and the thickness of base plate is identical with the height of guide groove, and described fin 4 is fixedly connected with by screw 8 with between conducting strip 6.
In the above-described embodiments, in order to heat conduction and radiating effect are better, therefore described baffle plate 10 is integrated with conducting strip 6, and is made up of brass H68, and described fin 4 is made up of 1060 aluminium strips.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
