Abstract

The utility model discloses an LED road lamp comprising a substrate and an LED lamp module group fixed on the front surface of the substrate, a heat radiator is fixed on the back surface of the substrate, the heat radiator comprises multiple heat radiating fins which are paralleled with each other, one end of the heat radiating fin is attached to the back surface of the substrate, the other end of the heat radiating fin is extended upward, multiple hot pipes are arranged on the substrate, the heated segments of the hot pipes are butted on the back surface of the substrate, the heat radiation segments of the hot pipes penetrate the heat radiator and are embedded into the heat radiation fins, the substrate is directly fixed in the metal lamp casing, the heat radiator and the LED lamp set are closed in the lamp casing, gas exhausting holes are arranged on the top end of the lamp casing, gas inlet holes are arranged at the bottom terminal of the lamp casing; because the multiple heat radiating fins which are paralleled can rapidly transfer the heat generated by the LED lamp set, the technology difficult problem of the heat radiation of the high power LED can be effectively solved, so that the service life of the LED road lamp can be ensured.

Description

A kind of LED street lamp

Technical field

The utility model relates to a kind of lighting, particularly a kind of high-power LED street lamp.

Background technology

In recent years, the LED lamp has obtained development fast, just progressively enters the general lighting field.Compare with traditional incandescent osram lamp and fluorescent lamp, the LED light fixture has that volume is little, caloric value is low, the advantage that power consumption is little, and can start by the low pressure low current, reaction speed is fast and the energy high frequency time is operated, long service life, thereby the title of " green illumination light source " is arranged.Existing high-power LED street lamp includes dozens of LED light emitting diode or more more, the gross calorific power of these LED light emitting diodes is very big during work, if these heats are led away and distributed untimelyly, can cause very big influence to its performance and life-span.

The utility model content

The purpose of this utility model provides a kind of high-power LED street lamp with excellent heat dispersion performance.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED street lamp, the LED lamp module that comprises substrate and be fixed in substrate front side, described substrate back is fixed with radiator, described radiator comprises the radiating fin that multi-disc is parallel to each other, radiating fin one end and substrate back are close to, and an end up extends.

Also be provided with many heat pipes on the described substrate, the heating section of described heat pipe is resisted against substrate back, and the radiating segment of heat pipe penetrates radiator and embeds in the radiating fin.

Be fixed with lamp housing on the described substrate, in this lamp housing was enclosed in radiator and LED lamp module, described lamp housing top was provided with steam vent, and described lamp housing bottom is provided with air admission hole.Described lamp housing comprises lamp housing and following lamp housing, and described steam vent is arranged on the lamp housing, and described air admission hole is arranged on down on the lamp housing.

The beneficial effects of the utility model are: because the radiating fin that multi-disc is parallel to each other can shift the heat that LED lamp module sends rapidly, solved the heat dissipation technology difficult problem of great power LED effectively, guaranteed the service life of LED street lamp.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to shown in Figure 1, a kind of LED street lamp, the LED lamp module that comprises substrate 1 and be fixed in substrate 1 front, described substrate 1 back side is fixed with radiator 2, described radiator 2 comprises the radiating fin that multi-disc is parallel to each other, and radiating fin one end and substrate 1 back side are close to, and an end up extends; Because the multi-disc radiating fin can shift the heat that LED lamp module sends rapidly, has solved the heat dissipation technology difficult problem of great power LED effectively, and guaranteed the service life of LED street lamp.

As improvement of the present utility model, also be provided with many heat pipes 3 on the described substrate 1, the heating section of described heat pipe 3 is resisted against substrate 1 back side, the radiating segment of heat pipe 3 penetrates radiator 2 and embeds in the radiating fin, heat pipe 3 can further be transduceed the heat in substrate 1 front on the radiator 2, particularly heat is conducted to uniformly the various piece of radiator 2, make the temperature of the temperature of entire radiator 2 and substrate 1 suitable, improved the efficient of radiating fin greatly, thereby can make radiator do littler gentlyer.

As further improvement of the utility model, be fixed with lamp housing on the described substrate 1, this lamp housing is the metal lamp housing, in this lamp housing is enclosed in radiator 2 and LED lamp module, described lamp housing top is provided with steam vent 41, and described lamp housing bottom is provided with air admission hole 51.Specifically, described lamp housing comprises lamp housing 4 and following lamp housing 5, described steam vent 41 is arranged on the lamp housing 4, described air admission hole 51 is arranged on down on the lamp housing 5, because substrate 1, LED lamp module and radiator 2 all are enclosed in the lamp housing, when being heated, the air in the lamp housing rises, cold air flows into from the air admission hole 51 of bottom and replenishes, promote steam vent 41 outflows of hot-air from the top, air is come in from air admission hole 51 endlessly like this, from steam vent 41, go out, the air of radiator 2 tops flows, be equivalent to install a fan, lamp housing and air admission hole 51 thereof and steam vent 41 have played the effect of a chimney, can efficiently conduct lamp housing to the heat on the radiator 2 fast.

Because: 1, radiating fin one end and substrate back are close to; 2, the heating section of heat pipe is resisted against substrate back, and the radiating segment of heat pipe then penetrates radiator and embeds in the radiating fin; 3, the lamp housing top is provided with steam vent, and described lamp housing bottom is provided with air admission hole; 4, substrate is directly fixed on the metal lamp housing; 1st, 2 two binding energy makes heat that LED lamp module sends shift and be distributed to uniformly rapidly on the radiating fin that multi-disc is parallel to each other, improved the utilization rate of radiating fin greatly, the 3rd be used in that the outer cross-ventilation of hot-air and lamp housing produces stack effect in the lamp housing, the 3rd, 4 utilization conducts street lamp to the heat on the radiating fin rapidly by hot-air and metal lamp housing.More than 4 integrated use solved the heat dissipation technology difficult problem of high-power LED street lamp effectively, guaranteed the service life of LED street lamp.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
