Description

TECHNICAL FIELD

[0001] The utility model relates to a lamp technical field, concretely relates to a ceiling lamp receiving head. BACKGROUND

[0002] In modern work and life, lamps are common and necessary household appliances, which are generally connected with 86 type wall switch and power supply circuit, and the opening and closing of lamps are achieved through the switch of wall switch. With the improvement of living quality, there are many wireless infrared remote control lamp holders and corresponding infrared remote controllers on the market, and the use of infrared remote controller to control wireless infrared remote control lamp holder enables users to turn on and off the lamps in the room.

[0003] In the prior art, an infrared receiving tube is usually used as a remote control signal receiver, but there is a gap between the existing infrared receiving tube and the shell, which allows visible light or other non-infrared light to enter the receiving tube, interfering with the reception of infrared signals, resulting in misoperation and reducing the anti-interference ability of the system, or dust, oil stains or other impurities may enter the inside of the shell through the gap and adhere to the photosensitive element or the filter of the infrared receiving tube, reducing the reception sensitivity of the infrared signal. SUMMARY

[0004] The utility model discloses to aim at the problem that the infrared receiving tube and the shell exist the gap in the prior art, provide a kind of ceiling lamp receiving head.

[0005] To achieve the above object, the utility model adopts the following technical scheme: a ceiling lamp receiving head, which comprises a bottom shell and a face shell that are mutually covered, a main board is installed in the bottom shell, an infrared induction head electrically connected to the main board is arranged on the main board facing the face shell, a sealing sleeve is sleeved on the infrared induction head, and a circular hole is provided on the face shell for the infrared induction head to extend out. The infrared induction head extends out through the circular hole, can directly receive the infrared signal from the outside, reduces signal attenuation or interference, and improves the sensing sensitivity.

[0006] Further, an arc chamfer is arranged on the outer wall of the end portion of the sealing sleeve. The design of the arc chamfer makes it easier to align the circular hole on the face shell when installing the sealing sleeve, plays a guiding role, and reduces the installation difficulty and time.

[0007] Further, the infrared induction head comprises a photosensitive element, a connecting plate and a pin, the photosensitive element is installed on the connecting plate, and the pin is connected with the photosensitive element through the connecting plate.

[0008] Further, the sealing sleeve is made of rubber. The rubber sealing sleeve can adapt to different sizes of circular holes and infrared induction heads, so that even if there is a slight deviation during installation, it can also be tightly fitted through elastic deformation.

[0009] The utility model discloses beneficial effect is: the sealing cover is set on the infrared induction head, installs the sealing cover to fill the gap between infrared induction head and the circular hole of face shell after finishing, plays the role of sealing and fixed, prevent dust, water vapor etc. from entering inside, the design of circular hole makes infrared induction head can effectively receive the infrared signal of outside, and the sealing property is ensured through sealing cover simultaneously.

[0015] Mark explanation: bottom shell 1, face shell 2, circular hole 21, mainboard 3, infrared induction head 4, photosensitive element 41, connecting plate 42, pin 43, sealing cover 5, arc chamfer 51. DETAILED DESCRIPTION

[0016] Referring to Figures 1-4 As shown in the figure, the technical scheme adopted in the embodiment is: a ceiling lamp receiving head, which comprises a bottom shell 1 and a face shell 2 that cover each other, the bottom shell 1 is provided with a mainboard 3, the mainboard 3 is provided with an infrared induction head 4 electrically connected to the mainboard 3, the infrared induction head 4 is provided with a sealing cover 5 made of rubber, and the face shell 2 is provided with a circular hole 21 corresponding to the infrared induction head 4.

[0017] The specific infrared induction head 4 comprises a photosensitive element 41, a connecting plate 42 and a pin 43. The photosensitive element 41 is installed on the connecting plate 42, the pin 43 is connected to the photosensitive element 41 through the connecting plate 42, the sealing cover 5 is sleeved on the photosensitive element 41, and the arc chamfer 51 is arranged on the outer wall of the end portion.

[0018] The utility model discloses a working principle: the sealing sleeve 5 is set to photosensitive element 41 then and the bottom shell 1 and the face shell 2 are covered together, and photosensitive element 41 extends the round hole 21 and the sealing sleeve 5 is extruded to the round hole 21 and is closely combined with the round hole 21. The arc chamfer 51 of the outer wall of the end of sealing sleeve 5 is designed, makes it easier to aim at the round hole 21 when installing, strengthens the sealing effect simultaneously, avoids the sealing failure due to improper installation. Sealing sleeve 5 can effectively fill the clearance between infrared induction head 4 and face shell 2 round hole 21, prevents dust, moisture and the like from entering the inside, ensures the long-term stable operation of internal circuit and element.

[0019] The above is only used to explain the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skill in the art should be covered in the claim range of the utility model.
