Abstract
The utility model discloses an LED lamp positioning structure which comprises a shell body, a circuit board and an LED lamp. The shell body is provided with a cavity used for containing the circuit board and the LED lamp. The LED lamp is electrically connected with the circuit board. The LED lamp positioning structure is characterized in that more than one first protruding part is arranged at the position, where the LED lamp is located, of the inner side of the shell body, and the first protruding part makes contact with the surface of the LED lamp. Compared with the prior art, the LED lamp positioning structure adopts the structure that the circuit board is used for positioning and the LED lamp is welded to the circuit board, and the thickness of the LED lamp positioning structure is the sum (deducting the thickness of the shell body) of the thickness of the circuit board and the thickness of the LED lamp; by means of the LED lamp positioning structure, more than one first protruding part is arranged at the position, where the LED lamp is located, of the inner side of the shell body, and the first protruding part is used for making contact with the surface of the LED lamp to fix the LED lamp, so that the thickness of the LED lamp positioning structure is just the same as the thickness of the LED lamp (deducting the thickness of the shell body); therefore the LED lamp positioning structure can be made thinner and lighter, materials are also saved, and cost is lowered.
Description
Technical field
The utility model relates to a kind of electronic whiteboard, particularly relates to a kind of lamp of the LED for infrared touch screen frame structure location structure.
Background technology
Touch-screen is a kind of multimedia presentation equipment, is the office of modernization multimedia and the requisite equipment of imparting knowledge to students.Wherein the positioning principle of interactive electric whiteboard has multiple, commonly used a kind of be the infrared ray location, it is the scan for networks that forms the horizontal and vertical direction by the infrared receiver and the transmitting tube that gather in the viewing area surrounding, just can be by infrared ray location positioning X, the Y coordinate of the horizontal and vertical direction that is blocked.
At present, within this infrared emission be comprised of infrared emitting and receiving tube and receiving tube array are hidden in the frame of touch-screen usually, border structure comprises housing, circuit board and LED lamp substantially, and existing frame structure, basically be that circuit-board card is held in to enclosure interior, the LED lamp is welded on circuit board, the thickness sum that the thickness of product is circuit board and LED lamp (removing the thickness of housing itself), cause the thickness of product bigger than normal, do not meet the modern and wish the thinner lighter requirement of electronic product.
The utility model content
Based on this, be necessary for the prior art problem, a kind of LED lamp location structure is provided, make product thinner lighter.
For solving the prior art problem, the utility model discloses a kind of LED lamp location structure, comprise housing, circuit board and LED lamp, described housing has the cavity of a placement circuit board and LED lamp, described LED lamp and circuit board are electrically connected, and described housing inboard is provided with the first protuberance more than in LED lamp place, the surface of described the first protuberance conflict LED lamp.
Further, described LED lamp comprises lamp holder and pin, described lamp holder and circuit board side by side, the end of described pin support circuit plate.
Further, described housing one side is provided with the second protuberance, and described the second protuberance support circuit plate is away from the end of pin.
Further, described housing inboard is provided with the 3rd protuberance, the end of described the 3rd protuberance conflict circuit board in the top of the second protuberance.
Further, the upper surface of the upper surface of described the second protuberance and pin is in the same level line.
Further, the quantity of described the first protuberance is two, is located at respectively the upper and lower surface of LED lamp.
The beneficial effects of the utility model are: use the circuit board location with respect to prior art, the LED lamp is welded on the structure on circuit board, the thickness sum that the thickness of product is circuit board and LED lamp (removing the thickness of housing itself).And this device is by adopting LED lamp location structure, be provided with the first protuberance more than in the housing inboard in LED lamp place, the first protuberance fixes the LED lamp for the surface of the LED lamp of conflicting, the thickness that makes this product is only the thickness of LED lamp (removing the thickness of housing itself), product just can be done thinner gentlyer, also save material, reduced cost.
The accompanying drawing explanation
The cross section structure schematic diagram that Fig. 1 is the utility model LED lamp location structure.
The specific embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Refer to Fig. 1, the utility model discloses a kind of LED lamp location structure, comprise housing 10, circuit board 20 and LED lamp 30, described housing 10 has the cavity 11 of a placement circuit board 20 and LED lamp 30, described LED lamp 30 is electrically connected with circuit board 20, and described housing 10 inboards are provided with the first protuberance 12 more than, the surface of described the first protuberance 12 conflict LED lamps 30 in LED lamp 30 places.In the present embodiment, the first protuberance 12 is preferably two, is separately positioned on the upper and lower surface of LED lamp 30, for locating LED lamp 30.
Described LED lamp 30 comprises lamp holder 31 and pin 32, described lamp holder 31 and circuit board 20 side by side, the end of described pin 32 support circuit plates 20.Pin 32 end insertions welding or paster are welded on circuit board 20, remaining support circuit board 20.
Described housing 10 1 sides are provided with the second protuberance 13, and described the second protuberance 13 support circuit plates 20 are away from the end of pin 32.The upper surface of the upper surface of described the second protuberance 13 and pin 32 is in the same level line.By the second protuberance 13 and the common also fixing circuit board 20 that supports of pin 32.
Described housing 10 inboards are provided with the 3rd protuberance 14, the end of described the 3rd protuberance 14 conflict circuit boards 20 in the top of the second protuberance 13.The also end of fixing circuit board 20 is clamped in described the 3rd protuberance 14 and the second protuberance 13 actings in conjunction.
