Description
Technical field
The utility model relates to advertising equipment field, particularly a kind of lamp box.
Background technology
Lamp box can be divided into indoor lamp box and outdoor lamp house according to the difference of installation site, and wherein outdoor lamp house has very high requirement for weatherability.Waterproof is that outdoor lamp house needs most two weatherabilities of consideration for inscribe with heat radiation, this two problems seems and solves all very well, but putting together, it is just very difficult to solve, because waterproof and heat radiation are two conflicting problems, waterproof just requires the good leak tightness of casing on the one hand, heat radiation just requires that the permeability of casing is good on the other hand, on same lamp box, has no idea not only to ensure seal but also ensure permeability.
Summary of the invention
The purpose of this utility model is to solve the problem, and devises a kind of lamp box.Specific design scheme is:
A kind of lamp box, comprise casing, LED module is installed in described casing, the left and right sides of described lamp box is provided with louvre, described louvre is connected with black box, described black box is installed in described casing, and described casing is provided with sensor, and described sensor is connected with described black box by wire.
The quantity of described sensor is two, and one of them is positioned at the below of described louvre, and another is positioned at described louvre.
Described louvre comprises diaphragm seal, and described diaphragm seal is connected with described body pivot, and the surrounding of described diaphragm seal is fixed with sealing joint strip.
Described LED module upper end is connected with power line, and the top that described power line runs through described casing is connected with casing outside, and the junction of described power line and casing is sealed by O-ring seal.
The sensor be positioned at below described louvre is level sensor, and the sensor being positioned at described louvre is humidity sensor.
Described black box comprises reed relay, electromagnetic relay, back-moving spring, described reed relay is electrically connected with described level sensor, humidity sensor, electromagnetic relay, described electromagnetic relay is placed in described back-moving spring, and the two ends, left and right of described electromagnetic relay are fixedly connected with the diaphragm seal of the described casing left and right sides.
By the lamp box that above-mentioned design of the present utility model obtains, its beneficial effect is:
Ensure the thermal diffusivity of casing in dry environments, under the environment having water, ensure the seal of casing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural scheme of mechanism of lamp box described in the utility model, as shown in Figure 1, a kind of lamp box, comprise casing 1, be provided with LED module 2 in described casing 1, the left and right sides of described lamp box 1 is provided with louvre 3, described louvre 3 is connected with black box 4, described black box 4 is installed in described casing 1, and described casing 1 is provided with sensor 5, and described sensor 5 is connected with described black box 4 by wire.
The quantity of described sensor 5 is two, and one of them is positioned at the below of described louvre 3, and another is positioned at described louvre 3.
Described louvre 3 comprises diaphragm seal 31, and described diaphragm seal 31 is rotationally connected with described casing 1, and the surrounding of described diaphragm seal 31 is fixed with sealing joint strip 32.
Described LED module 2 upper end is connected with power line, and the top that described power line runs through described casing 1 is connected with casing 1 outside, and the junction of described power line and casing 1 is sealed by O-ring seal 11.
The sensor 5 be positioned at below described louvre 3 is level sensor, and the sensor 5 being positioned at described louvre 3 is humidity sensor.
Described black box 4 comprises reed relay 41, electromagnetic relay 42, back-moving spring 43, described reed relay 41 is electrically connected with described level sensor, humidity sensor, electromagnetic relay 42, described electromagnetic relay 42 is placed in described back-moving spring 43, and the two ends, left and right of described electromagnetic relay 42 are fixedly connected with the diaphragm seal 31 of described casing 1 left and right sides.
Under drying regime, click electromagnetic relay 42 continuous firing, described diaphragm seal 31 is attracted to open, described back-moving spring 43 is in compressive state, described humidity sensor, level sensor can be monitored the situation around louvre 3, when occurring casing lower end ponding, rain etc. situation time, described humidity sensor, level sensor can by Signal transmissions to reed relay 41, because electromagnetic relay 42 pairs of electric current induction sensitivity are lower, so described reed relay 41 plays the effect of signal receiver, now described reed relay 41 open circuit, electromagnetic relay 42 is stopped power supply and is lost magnetic force, described back-moving spring 43 promotes diaphragm seal 31 and rotates and close, make casing 1 airtight.
After environment appropriate ventilation, sensor 5 can send signal to reed relay 41, and reed relay 41 can close, and electromagnetic relay 42 works and produces magnetic force, overcomes back-moving spring 43 elastic force and is pulled open by described diaphragm seal 31, recovers to ventilate.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
