Description
Technical field
The utility model relates to LED negative pressure tester.
Background technology
LED lamp is before dispatching from the factory, and its impermeability must be detected in the position for sealing, makes its water resistance reach request for utilization.In the prior art, wherein one tests bubble-tight method by observing bubble, be in the patent documentation of 2014.6.4, disclose a kind of light fixture air-leakage test test unit and method as be 201210492686.1 applyings date at application number being 2012.11.27 publication date, air-tightness detection method disclosed in the document needs light fixture to put in water tank to observe bubble situation, therefore, on the one hand, the time of test is longer, on the other hand, could pack after needing after having tested that oven dry is dried to light fixture.
Except the above-mentioned method that light fixture impermeability is detected, in the prior art, also has the impermeability adopting the mode of negative pressure to test light fixture, this method needs the technical matters of drying light fixture and drying before overcoming packaging, be disclose the bubble-tight device of a kind of test in the patent documentation of 2012.10.24 as be 201210201771.8 applyings date at application number being 2012.6.19 publication date, this device needs for light fixture arranges a closed cavity, therefore, complex structure, the time of test is long.
Summary of the invention
In order to ensure the impermeability of light fixture, shorten the test duration, simplify structure, the utility model provides a kind of LED negative pressure tester.
For achieving the above object, a kind of LED negative pressure tester, comprises housing, valve body, suction nozzle, negative pressure gauge and vacuum generator, valve body is located on housing, suction nozzle is connected on valve body, and negative pressure gauge is connected between valve body and suction nozzle, and vacuum generator is connected on valve body.
Further, valve body is connected with oil mist collector.
Further, vacuum generator is connected with residual voltage bleed valve in turn, filters pressure regulation and oil mist separator.
Further, described housing comprises shell, be located at the protecgulum of housing front and be located at the bonnet at shell rear portion.
Further, described valve body is five mouthfuls of three hand valves.
Further, described vacuum generator has air pump switch.
The beneficial effects of the utility model are: owing to being provided with suction nozzle on valve body, the effect of this suction nozzle is adsorbed onto on light fixture, allow the negative pressure of vacuum hole of light fixture communicate with valve body, when startup vacuum generator, the annular seal space of light fixture knows from experience formation negative pressure, then valve body, observe negative pressure gauge whether to change, if changed, then illustrate that impermeability is bad, if not change, then illustrate that impermeability is good.Utilize LED negative pressure tester of the present invention, can effectively guarantee to need the part of waterproof to test at light fixture, the bubble-tight detection of light fixture can reach the classification of waterproof of IP66, and it is convenient, fast to operate, observe the whether good speed of impermeability soon by negative pressure gauge, therefore, test required time is few, meanwhile, the structure of this LED negative pressure tester is simple.Owing to being provided with oil mist collector, therefore, be convenient to collect from the mist of oil in LED lamp, mist of oil can be reduced and enter in vacuum generator.Owing to being provided with residual voltage bleed valve, filtering pressure regulation and oil mist separator, therefore, effectively mist of oil and gas can be separated, and the effect of air filtration pressure regulation can be realized.
Accompanying drawing explanation
Fig. 1 is the stereographic map of LED negative pressure tester.
Fig. 2 is the exploded view of LED negative pressure tester.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, LED negative pressure tester comprises housing 1, valve body 2, suction nozzle, negative pressure gauge 3, vacuum generator 4, oil mist collector 5, filters pressure regulation and oil mist separator 6, residual voltage bleed valve.
As shown in Figure 2, described housing 1 comprises shell 11, be located at the protecgulum 12 of shell 11 front portion and be located at the bonnet 13 at shell 11 rear portion; Hole 111 is provided with in the both sides of shell 11; In the bottom of shell 11, support foot 112 is installed.
Described valve body 2 is five mouthfuls of three hand valves, and described valve body 2 is fixed on protecgulum 12.
Suction nozzle is connected on valve body 2, for being adsorbed onto LED lamp, the negative pressure of vacuum hole of LED lamp is communicated with valve body 2.Negative pressure gauge 3 is connected between valve body 2 and suction nozzle, for observing the pressure in LED lamp seal chamber.Whether described vacuum generator 4 is connected on valve body 2, and vacuum generator 4 has air pump switch, start for controlling vacuum generator.Vacuum generator 4 is connected with in turn residual voltage bleed valve, filters pressure regulation and oil mist separator 6, filter pressure regulation and be connected air-source with oil mist separator 6.
The method utilizing present embodiment LED negative pressure tester to test LED negative pressure is: by suction in LED lamp; the negative pressure of vacuum hole of LED lamp is allowed to communicate with valve body 2; when startup vacuum generator 4; the annular seal space of LED lamp knows from experience formation negative pressure; in vacuum; part mist of oil enters in oil mist collector 5, can reduce the mist of oil entered in vacuum generator, effectively protect vacuum generator.When the seal chamber of LED lamp reaches the requirement of vacuum tightness, whether valve body 2, observe negative pressure gauge and change, if changed, then illustrates that impermeability is bad, if not change, then illustrates that impermeability is good.Utilize LED negative pressure tester of the present invention, can effectively guarantee to need the part of waterproof to test at light fixture, the bubble-tight detection of light fixture can reach the classification of waterproof of IP66, and it is convenient, fast to operate, observe the whether good speed of impermeability soon by negative pressure gauge, therefore, test required time is few, meanwhile, the structure of this LED negative pressure tester is simple.
