Abstract
The utility model discloses a control device of a lamp. The control device comprises a base; an upper cover is spliced above the base; side covers are respectively arranged at the two ends of the upper cover; and diversion grooves are respectively formed at the two ends of the upper cover. As the diversion grooves are formed on the upper cover, when water drops on the upper cover, part of the water can flow to the diversion grooves at the two ends of the upper cover, then flows to the upper end surface of a first side plate along the diversion grooves, and finally flows out, so that the control device has good waterproof effect. Furthermore, the control device has the advantages of simple structure and low manufacture cost.
Description
Technical field
The utility model relates to a kind of control device of lamp.
Background technology
The control device of lamp is a kind of use semi-conductor electricity sub-element, converts direct current or low-frequency ac voltage to high-frequency ac voltage, drives the electronic-controlled installation of light source works such as low-pressure gaseous discharge lamp (bactericidal lamp), tungsten halogen lamp.
With the control device of lamp be installed on similar humidity such as bathroom bigger local time, require the control device of lamp must have favorable waterproof property (requirement is at least IP43: prevent that promptly the water intrusion that sprays is rainproof, or prevent that the water that sprays less than the direction of 60 degree with vertical angle from entering light fixture and causing damage).
Current, a kind of " control device of lamp " arranged, it comprises base, and described base comprises base plate, and it is the bottom that the top of base plate is provided with the base plate, be the cavity of sidewall with first side plate and second side plate.The width of described first side plate is greater than the width of second side plate, and the intersection of first side plate and second side plate forms protruding rank, be provided with wiring board in this cavity, wiring board is provided with electronic component, the top amalgamation of described base has loam cake, and the top of described base also is respectively arranged with side cover corresponding to the two ends of loam cake.The control device of the lamp of this structure, when water droplet during to loam cake, part water flows away along the dual-side of loam cake, part then can infiltrate into the inner surface place of side cover along the two ends of loam cake, when serious, can infiltrate into electronic component always, thereby produce great potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of control device of lamp of simple in structure, good water-proof effect, and this control device can use in the bigger places of similar humidity such as bathrooms.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of control device of lamp comprises base, and the top amalgamation of described base has loam cake, and the two ends of loam cake are respectively arranged with side cover, and the two ends of described loam cake are respectively arranged with diversion groove.Loam cake is provided with diversion groove, and when water droplet during to loam cake, part water flow in the diversion groove at loam cake two ends, and flow to the upper surface of first side plate along diversion groove, and final the outflow, the utlity model has the excellent waterproof effect thereby make.
In the technique scheme, the inner surface of described side cover is provided with boss corresponding to the diversion groove place, and the external surface shape of this boss and the inner surface configuration of diversion groove are suitable.Be provided with boss, and the inner surface configuration of the external surface shape of boss and diversion groove is suitable can be so that the least possible entering in the diversion groove of water, directly the side from loam cake flows away.
In the technique scheme, described diversion groove is higher than the bottom of diversion groove away from the loam cake center near the bottom at loam cake center.When water flow to this diversion groove, can make current flow to the bottom of diversion groove faster, thereby water is comparatively fast flowed out away from the loam cake center.
In the technique scheme, described base comprises base plate, and it is the bottom that the top of base plate is provided with the base plate, be the cavity of sidewall with first side plate and second side plate.The width of described first side plate is greater than the width of second side plate, and the intersection of first side plate and second side plate forms protruding rank.
In the technique scheme, described second side plate is provided with through hole, and the buckle amalgamation that loam cake is provided with by inner surface is on second side plate.
The utility model compared with prior art has following beneficial effect:
1) the utility model is because loam cake is provided with diversion groove, when water droplet during to loam cake, part water flow in the diversion groove at loam cake two ends, flow to the upper surface and final outflow of first side plate along diversion groove, water can not enter into cavity, even the utlity model has the excellent waterproof effect yet.
2) simple in structure, the low cost of manufacture of the utility model.

Fig. 2 is a perspective view of the present utility model.
Fig. 3 is a longitudinal section of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 3, a kind of control device of lamp comprises base 1, and described base 1 comprises base plate 10, and the top of base plate 10 is provided with base plate 10 and is the bottom, is the cavity of sidewall with first side plate 12 and second side plate 14.The width of described first side plate 12 is greater than the width of second side plate 14, and the intersection of first side plate 12 and second side plate 14 forms protruding rank.Be provided with wiring board 7 in this cavity, wiring board 7 is provided with electronic component.
Described second side plate 14 is provided with buckle 32 amalgamations that 140, one loam cakes 3 of through hole are provided with by inner surface on second side plate 14.The outer surface width of the inner surface width of described loam cake 3 and second side plate 14 is suitable, the outer surface width of the outer surface width of loam cake 3 and first side plate 12 is suitable, when loam cake 3 amalgamations are on base 1, can make loam cake 3 and base 1 comparatively ideal installation like this, and omit the tool sealing effectiveness.
The top of described base 1 also is respectively arranged with side cover 5 corresponding to the two ends of loam cake 3, the two ends of described loam cake 3 are respectively arranged with diversion groove 30, the inner surface of described side cover 5 is provided with boss 50 corresponding to diversion groove 30 places, and the inner surface configuration of the external surface shape of this boss 50 and diversion groove 30 is suitable.Diversion groove 30 is blocked preferably by the inner surface of side cover 5.
Preferably, described diversion groove 30 is higher than the bottom of diversion groove 30 away from loam cake 3 centers near the bottom at loam cake 3 centers.Such advantage is when water flow to this diversion groove 30, can make water comparatively fast flow to the bottom of diversion groove 30 away from loam cake 3 centers, thereby water is comparatively fast flowed out.
When the utility model is installed in bigger place such as the humidity that is similar to the bathroom, very easily cause water droplet to loam cake 3.When water droplet during to loam cake 3, part water flows away along the dual-side of loam cake 3, part flow in the diversion groove 30 at loam cake 3 two ends, and flow to the upper surface of first side plate 12 along diversion groove 30, and final the outflow, thereby can prevent that sealing enters into cavity, also promptly the utlity model has the excellent waterproof effect.
