Abstract
A sealing structure of LED (light emitting diode) street lamps comprises a radiator (1), protective glass (2) and an LED (3), and is characterized in that a sealant (4) is filled at the inner side of the boundary between the protective glass (2) and the radiator (1); a drying agent (5) is placed in the space of the LED (3); and an electric lead (6) is led out through the sealant (4) to be connected with a power supply. Compared with the prior art, the sealing structure has the following advantages: as the LED as a luminous body is installed in the sealed space surrounded by the radiator, the protective glass, the sealant and an insulated sealing body, the LED is consequently and totally isolated from the outside, and the external humidity, dust and the like can not enter the working space of the LED, so that the long-term stable work of the LED is ensured. Meanwhile, the drying agent placed in the sealed space ensures the air in the sealed space is fully dried, and the normal work of the LED is prevented from being affected by the humidity existing in the sealed space.
Description
Technical field
The utility model relates to a kind of road illuminating lamp, particularly a kind of hermetically-sealed construction of LED street lamp, and be used for the hermetically-sealed construction that square, garden, factory, view etc. locate to have the LED street lamp of same structure.
Background technology
The hermetically-sealed construction of existing LED street lamp or Tunnel Lamp, usually by shell, transparent lower cover, sealing strip, trim ring, compositions such as holding screw, adopt shell and the transparent structure of cover split-type down, under such structure, for solving the sealing problem of LED, usually adopt and between shell and transparent lower cover, install sealing strip additional, the way that compresses the sealing strip between shell and the transparent lower cover with trim ring seals then, and sealing strip is difficult to reach the effect of sealing fully, and can degenerate with age, in case seal failure, LED will be subjected to moisture, dust, the erosion of bacterium, the light efficiency of street lamp and whole service life will be affected.
The utility model content
The purpose of this utility model is to provide a kind of hermetically-sealed construction of LED street lamp, the hermetically-sealed construction of this LED street lamp has excellent sealing performance, and seal cavity is built-in with drier simultaneously, makes the inside air drying, guarantee the LED operate as normal, prolong the service life of LED street lamp.
A kind of hermetically-sealed construction of LED street lamp comprises radiator 1, cover plate 2, LED 3, it is characterized in that: the boundary inboard between cover plate 2 and radiator 1 is filled with fluid sealant 4, is placed with drier 5 in the space at LED3 place, and conductor wire 6 is drawn with power supply by fluid sealant 4 and is connected.
With prior art relatively, the utility model has the advantages that: the LED as illuminator is installed in the seal cavity that is impaled by radiator, cover plate, fluid sealant and insulated enclosure body, therefore LED isolates fully with the external world, extraneous moisture, the working space that dust can't enter LED have guaranteed that LED works steadily in the long term.Simultaneously, in seal cavity, be placed with drier, guarantee that the air in the seal cavity is fully dry, can avoid having moisture in the seal cavity and the operate as normal that influences LED.

The specific embodiment
Embodiment 1:
As shown in Figure 1 and Figure 2, a kind of hermetically-sealed construction of LED street lamp, comprise radiator 1, cover plate 2, LED3, it is characterized in that: the boundary inboard between cover plate 2 and radiator 1 is filled with fluid sealant 4, is placed with drier 5 in the space at LED 3 places, and conductor wire 6 is drawn with power supply by fluid sealant 4 and is connected.Totally 50 of the white light LEDs of every 3W of LED 3 employings, radiator 1 is the aluminium alloy heat radiator of band radiating fin, and cover plate 2 adopts safety glass, and fluid sealant 4 usefulness have the construction structure glue of good weatherability properties energy, and drier 5 adopts molecular sieve desiccants.Present embodiment power 150W can work out of doors for a long time the LED phenomenon of making moist can not take place.
Claims (1)
1. the hermetically-sealed construction of a LED street lamp, comprise radiator (1), cover plate (2), LED (3), it is characterized in that: the boundary inboard between cover plate (2) and radiator (1) is filled with fluid sealant (4), be placed with drier (5) in the space at LED (3) place, conductor wire (6) is drawn with power supply by fluid sealant (4) and is connected.
