Abstract
The utility model discloses an LED street lamp with respiration function, which comprises a sealed lamp housing (1), wherein a control circuit and a plurality of LED lamp bodies (2) are arranged in the lamp housing (1), and a waterproof and dustproof breathable film (3) connected at the inner and outer parts of the lamp housing (1). The waterproof and dustproof breathable film can maintain the balance of temperature, humidity and air pressure inside and outside the housing of the lamp in time in terms of temperature, humidity and air pressure according to the difference of temperature, humidity and air pressure inside and outside the housing of the lamp, the phenomenon of dewing in the street lamp is solved, so as to enhance the quality of the street lamp, and the illumination intensity of the street lamp can be obviously enhanced. The LED street lamp with respiration function has the advantages of simple structure, low cost, strong practicability and popularization value.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is meant a kind of LED street lamp with respiratory function.
Background technology
The working time of street lamp generally is that at 6 in evening is to point in mornings six, because LED street lamp stream time is long, and the degree of protection of lamp body is generally more than IP65, LED is operated in the sealed environment basically, can not keep air pressure balance inside and outside the lamp body, during work, temperature in the lamp body is in very high state, cause having temperature difference inside and outside the road lamp body, after closing street lamp, air in the lamp body is in more much higher than ambient temperature, and the hot-air in the lamp body can slowly solidify the short grained globule like this, forms the dewfall phenomenon; The consequence of dewfall will form the globule, if the globule in the street lamp can not volatilize or distribute, can cause bad phenomenon such as circuit board short circuit, the reduction of LED device luminous efficiency, has a strong impact on the operate as normal and the road lighting of street lamp.
When the LED street lamp is under the working condition, LED will produce heat, phenomenons such as the temperature difference, psychrometric difference, draught head can occur inside and outside the road lamp body, mainly be the draught head problem, because can not cross-ventilation inside and outside the lamp body, will occurring of dewfall phenomenon, the dewfall phenomenon is serious, also is in countdown fast the service life of street lamp, can increase terminal use's use cost like this, if short circuit phenomenon appears in the street lamp circuit board, even can influence the operate as normal of whole electrical network.
The utility model content
The purpose of this utility model is to provide a kind of lamp body internal and external temperature, humidity, air pressure balance kept, and solves the LED street lamp of the band respiratory function of street lamp dewfall phenomenon.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the LED street lamp of band respiratory function, the lamp casing that comprises sealing, be provided with control circuit and several LED lamp bodies in the lamp casing 1, described lamp casing is provided with and connects the inside and outside water proof and dust proof ventilated membrane of lamp casing.
Owing to adopted above-mentioned structure, the water proof and dust proof ventilated membrane can be in time according to internal-external temperature difference, psychrometric difference, the draught head of road lighting lantern housing, aspect temperature, humidity, air pressure, keep lamp casing internal and external temperature, humidity, air pressure balance, solve street lamp " dewfall " phenomenon, thereby improve the quality of street lamp, street lamp illumination also can obviously improve.The utility model is simple in structure, and cost is low, has very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the stereogram of the LED street lamp of band respiratory function.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the LED street lamp of band respiratory function described in the utility model, the lamp casing 1 that comprises sealing, be provided with control circuit and several LED lamp bodies 2 in the lamp casing 1, described lamp casing 1 is provided with connection lamp casing 1 inside and outside water proof and dust proof ventilated membrane 3. water proof and dust proof ventilated membranes 3 and selects " POV/M12X1.5HA " Ge Er water proof and dust proof ventilated membrane for use, according to the spatial volume difference in the lamp casing 1, select for use the specifications and models of water proof and dust proof ventilated membrane also different. " POV/M12X1.5HA " Ge Er water proof and dust proof ventilated membrane has good degree of protection, pliability, shock resistance, aqueous vapor conductivity and resisting temperature function etc.; Its weatherability is very good, can be in outdoor long-term stable operation. " POV/M12X1.5HA " Ge Er water proof and dust proof ventilated membrane structure is that the screw-type shell is furnished with silica gel O type circle, and the expanded PTFE ventilated membrane of trickle loose structure passes through inside and outside the ventilative continuous balance lamp body and the pressure differential between environment of living in; In addition, water, flying dust and dirt are stopped by the film of hydrophobic structure, with the LED street lamp service life of guaranteeing under extreme environment, to work. the water proof and dust proof ventilated membrane can be in time according to internal-external temperature difference, psychrometric difference, the draught head of road lighting lantern housing, aspect temperature, humidity, air pressure, keep lamp casing internal and external temperature, humidity, air pressure balance, solve street lamp " dewfall " phenomenon, thereby improve the quality of street lamp, street lamp illumination also can obviously improve.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
