Abstract
The utility model discloses a self-exhausting heat dissipation type road lamp which comprises an outer shell. A light emitting element, a power source and a power source box are arranged in the outer shell, the power source box is provided with a power source box cover plate located on the back of the outer shell, and the outer shell is further provided with a vent valve formed by a pressure limiting valve. According to the self-exhausting heat dissipation type road lamp, the vent valve is arranged on the outer shell, work pressure of the vent valve is set, so that when air pressure in the outer shell reaches the work pressure due to temperature rise, the vent valve is opened automatically, air pressure in the outer shell returns to normal, the problem that overhigh air pressure damages the light emitting element and other parts is avoided, and long-time stable work of the road lamp can be ensured.
Description
Technical field
The utility model relates to a kind of lighting, is specifically related to a kind of street lamp.
Background technology
Street lamp usually all comprises shell and establishes the parts such as in the enclosure light-emitting component, power supply; in shell, be formed be used to the light-emitting component box that holds light-emitting component be used to holding the power pack of power supply; on power pack, usually also be provided with detachable battery case cover plate; between light-emitting component box and power pack, be interconnected, both combine the formation closed cavity.In the course of work, because light-emitting component produces a large amount of heat, the temperature of light-emitting component surrounding space raises, and in order in time heat to be discharged, on shell, is typically provided with radiator structure.But, even be provided with radiator structure, temperature in described closed cavity also can be apparently higher than ambient temperature, therefore after light-emitting component work, temperature in closed cavity can raise gradually, makes the air pressure in enclosure space also increase, because the closed cavity sealing is better, gas can not be discharged in time, and too high air pressure can exert an influence to the life-span of light-emitting component and other parts.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of from exhaust heat dissipation type street lamp, this street lamp can automatically be discharged the light-emitting component ambient air, makes to keep normal air pressure around light-emitting component, guarantees light-emitting component and miscellaneous part normal operation.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind ofly from exhaust heat dissipation type street lamp, comprise shell, in shell, be provided with light-emitting component, power supply and power pack, power pack is provided with the power pack cover plate that is positioned at the shell dorsal part, it is characterized in that, on described shell, also is provided with the vent valve consisted of pressure limiting valve.
Described vent valve is arranged on the dorsal part of shell, in addition, also can be arranged on front side or other positions, as long as can be communicated with the inner chamber of shell.Further, this vent valve is arranged on the power pack cover plate, is convenient to like this design and installation.
Described light-emitting component is provided with lens outward, the effect of these lens is to obtain the effect of lamp that light fixture obtains by secondary light-distribution, with horizontal 135 degree that certain material is made, and vertical 75 degree minus lenses, the street lamp that makes to be arranged on road can irradiate road surface more uniformly, reduces lighting blind zone on large degree; These lens can use the lens of being made by high borosilicate optical glass.Further, light-emitting component is provided with light source waterproof apron, lens and lens chuck ring outward successively, can prevent that like this steam from entering, and is convenient to fixed lens.
The back side of described shell is the arc of outwardly convex, and this back side is provided with latticed radiator structure, and this latticed radiator structure can utilize cross-ventilation to carry out high efficiency and heat radiation.
The utility model compared with prior art has following beneficial effect:
In the utility model, on shell, be provided with vent valve, by setting the operating pressure of vent valve, while when the rising of the air pressure Yin Wendu in shell, reaching this operating pressure, vent valve is opened automatically, make the shell internal gas pressure recover normal, thereby avoid damaging because air pressure is too high the parts such as light-emitting component, guarantee street lamp steady operation for a long time.
The accompanying drawing explanation
Fig. 1～Fig. 3 is the structural representation of a specific embodiment from exhaust heat dissipation type street lamp of the present utility model, and wherein, Fig. 1 is front view, and Fig. 2 is top view, and Fig. 3 is upward view.
Fig. 4 is from the part explosive view of exhaust heat dissipation type street lamp shown in Fig. 1～Fig. 3 is.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Referring to Fig. 1～Fig. 4, the present embodiment from exhaust heat dissipation type street lamp, comprise shell 1, in shell 1, be provided with light-emitting component 9, power supply 2 and power pack 11, power pack 11 is provided with the power pack cover plate 4 that is positioned at shell 1 dorsal part.Wherein, described light-emitting component 9 is three, and this light-emitting component 9 is for being used the integrated optical source of high brightness 45MIL chip.Light-emitting component 9 is outer is provided with light source waterproof apron 8, lens 7 and lens chuck ring 6 successively, wherein, the lens of described lens 7 for adopting high borosilicate optical glass to make, the lighting angle that makes light-emitting component 9 is laterally 135 degree, is vertically 70 degree.The back side of described shell 1 is the arc of outwardly convex, and this back side is provided with latticed radiator structure 10, utilizes cross-ventilation to carry out high efficiency and heat radiation.Described power supply 2 is arranged in power pack 11, and 4 one one-tenth of described power pack cover plate are tabular, and it is shaft-like that other end becomes, wherein, plate portion is placed on power pack 11, and stem portion extends to the curved rear place of shell 1, is provided with power pack water proof ring 3 between this power pack cover plate 4 and power pack 11.
Referring to Fig. 1～Fig. 4, the back side of described shell 1 is provided with the vent valve 5 consisted of pressure limiting valve, and this vent valve 5 is arranged at the junction of plate portion and stem portion in power pack cover plate 4, and this vent valve 5 is communicated with inner chamber and the space outerpace of shells 1.The operation principle of this vent valve 5 is similar to the air bleeding valve in pressure cooker, and when the air pressure in shell 1 inner chamber was greater than the operating pressure of setting, vent valve 5 was opened automatically, discharge the gas of the inside, make air pressure recover normal value, vent valve 5 is closed automatically subsequently, thereby avoids the air pressure in shell 1 too high.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, in this enforcement, described vent valve 5 is arranged on the curved rear of shell 1.
