Description

light control device

technical field

The utility model relates to a lamp control device.

Background technique

The lamp control device is an electronic control device that uses semiconductor electronic components to convert DC or low-frequency AC voltage into high-frequency AC voltage, and drives low-pressure gas discharge lamps (germicidal lamps), tungsten halogen lamps and other light sources to work.

When the light control device is installed in a place with high humidity such as a bathroom, the light control device must have good waterproof performance (required to be at least IP43: that is, to prevent the sprayed water from intruding into the rain, or to prevent the angle between the vertical and the vertical Water sprayed in a direction less than 60 degrees enters the lamp and causes damage).

Currently, there is a "lamp control device", which includes a base, the base includes a bottom plate, and a cavity with the bottom plate as the bottom and a first side plate and a second side plate as side walls is provided above the bottom plate. The width of the first side plate is greater than the width of the second side plate, and a convex step is formed at the junction of the first side plate and the second side plate, a circuit board is arranged in the cavity, and the circuit board is provided with electronic components, An upper cover is assembled above the base, and side covers are respectively arranged above the base corresponding to two ends of the upper cover. In the lamp control device with this structure, when water drops to the upper cover, part of the water will flow away along the two sides of the upper cover, while some will penetrate to the inner surface of the side cover along the two ends of the upper cover. In severe cases, It will penetrate all the way to electronic components, resulting in a great safety hazard.

Utility model content

The purpose of the utility model is to provide a lamp control device with simple structure and good waterproof effect, which can be used in places with relatively high humidity such as bathrooms.

In order to solve the above technical problems, the utility model is solved through the following technical solutions:

A control device for a lamp, comprising a base, an upper cover is assembled above the base, side covers are respectively arranged at both ends of the upper cover, and guide grooves are respectively arranged at both ends of the upper cover. The upper cover is provided with diversion grooves, and when water drops onto the upper cover, part of the water flows into the diversion grooves at both ends of the upper cover, and flows along the diversion grooves to the upper end surface of the first side plate, and finally flows out, thereby Make the utility model have good waterproof effect.

In the above technical solution, the inner surface of the side cover is provided with a boss corresponding to the position of the diversion groove, and the shape of the outer surface of the boss is adapted to the shape of the inner surface of the diversion groove. The boss is provided, and the shape of the outer surface of the boss matches the shape of the inner surface of the diversion groove so that as little water as possible enters the diversion groove and flows away directly from the side of the upper cover.

In the above technical solution, the bottom of the guide groove near the center of the upper cover is higher than the bottom of the guide groove away from the center of the upper cover. When the water flows to the diversion groove, the water flow can be made to flow quickly to the bottom of the diversion groove away from the center of the upper cover, so that the water can flow out quickly.

In the above technical solution, the base includes a bottom plate, and a cavity with the bottom plate as the bottom and the first side plate and the second side plate as the side walls is provided above the bottom plate. The width of the first side plate is greater than that of the second side plate, and a convex step is formed at the junction of the first side plate and the second side plate.

In the above technical solution, the second side plate is provided with a through hole, and the upper cover is assembled on the second side plate through the buckle provided on the inner surface.

Compared with the prior art, the utility model has the following beneficial effects:

1) Since the utility model is provided with diversion grooves on the upper cover, when water drops to the upper cover, part of the water flows into the diversion grooves at both ends of the upper cover, and flows along the diversion grooves to the upper end surface of the first side plate And eventually flow out, water will not enter the cavity, even if the utility model has a good waterproof effect.

2) The utility model has simple structure and low manufacturing cost.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

Referring to FIGS. 1 to 3 , a lamp control device includes a base 1 , the base 1 includes a bottom plate 10 , and above the bottom plate 10 is provided with the bottom plate 10 as the bottom, a first side plate 12 and a second side plate 14 cavity in the sidewall. The width of the first side panel 12 is greater than that of the second side panel 14 , and a junction between the first side panel 12 and the second side panel 14 forms a convex step. A circuit board 7 is provided in the cavity, and the circuit board 7 is provided with electronic components.

The second side plate 14 is provided with a through hole 140 , and an upper cover 3 is assembled on the second side plate 14 through the buckle 32 provided on the inner surface. The width of the inner surface of the loam cake 3 is adapted to the width of the outer surface of the second side plate 14, and the width of the outer surface of the loam cake 3 is adapted to the width of the outer surface of the first side plate 12, so that when the loam cake 3 is put together When on the base 1, the upper cover 3 and the base 1 can be installed ideally, and have a little sealing effect.

The top of the base 1 is also respectively provided with side covers 5 corresponding to the two ends of the upper cover 3, and the two ends of the upper cover 3 are respectively provided with guide grooves 30, and the inner surface of the side cover 5 is corresponding to the guide grooves. The flow groove 30 is provided with a boss 50 , the shape of the outer surface of the boss 50 is adapted to the shape of the inner surface of the flow guide groove 30 . In this way, the guide groove 30 can be better shielded by the inner surface of the side cover 5 .

Preferably, the bottom of the guide groove 30 close to the center of the upper cover 3 is higher than the bottom of the guide groove 30 away from the center of the upper cover 3 . The advantage of this is that when the water flows to the diversion groove 30, the water can flow to the bottom of the diversion groove 30 away from the center of the upper cover 3 quickly, so that the water can flow out quickly.

When the utility model is installed in a place with high humidity such as a bathroom, it is very easy to cause water to drop onto the upper cover 3 . When water drops onto the upper cover 3 , part of the water flows away along the two sides of the upper cover 3 , and part of the water flows into the guide grooves 30 at both ends of the upper cover 3 , and flows along the guide grooves 30 to the first side plate 12 The upper end surface of the utility model has a good waterproof effect and finally flows out, thereby preventing water from entering the cavity.
