Detailed ways

As for the LED lighting technology involved in the present invention, if it only belongs to the common and well-known prior art by those skilled in the art, due to the relationship of space, it will not be described in detail.

Below, introduce with regard to the content of the present utility model.

Compared with the prior art, the lamp of the utility model overcomes the defect that the light emitted by the LED lighting tube is too concentrated or cannot change the direction, and can adjust the emission angle of the light.

The installation plate in the utility model has the characteristic of being bendable. For the bendable property of the mounting plate, various technical solutions can be used to realize it, three of which are introduced below.

In the first method, the mounting board is made of a flexible printed circuit board.

The installation board made of flexible printed circuit board can be directly welded with LED lighting tubes on it. Flexible printed circuit boards are also called flexible printed boards. In order to facilitate understanding and implementation, the relevant national standards are provided below:

a. Single- and double-sided flexible printed boards with through-connections, the implemented standards are: "General Specifications for Printed Boards" (GB/T 16261-1996), "Single- and double-sided flexible printed boards with through-connections" Board Technical Conditions" (GB/T 14515-1993).

b. Single-sided and double-sided flexible printed boards without through-connection, the implemented standards are: "General Specification for Printed Boards" (GB/T 16261-1996), "Single-sided and double-sided flexible printed board technology without through-connection" Conditions" (GB/T 14516-1993).

c. For flexible multilayer printed boards with through connections, the implemented standards include: "General Specifications for Printed Boards" (GB/T 16261-1996), "Specifications for Flexible Multilayer Printed Boards with Through Connections" ( GB/T18334-2001).

Implementers can check the models and specifications of flexible printed circuit boards from the above standards, and select flexible printed circuit boards of appropriate models and specifications to produce flexible mounting boards that can be bent back and forth. When selecting, it should be considered comprehensively together with other contents of the specific plan to determine the thickness of the material, single-sided or double-sided welding, whether to use multi-layer technical solutions, etc., to ensure that both bending and welding are not will fall off.

The second method is to select a suitable bendable plastic plate (or rubber plate) and install a hollow copper rivet on it. The copper wire of the pin of the LED lighting tube passes through the hollow of the front of the copper rivet and welds on the reverse side. In addition, the connected wires can also be soldered here.

The third method is to use two bendable plastic plates (or rubber plates) to sandwich the LED lighting tube, and the wires are directly welded to the pins of the LED lighting tube. Using this method, LED lighting tubes with protruding shoulders should be purchased or specially manufactured. The purpose of this requirement is to make the protruding shoulders clamped between two bendable plastic plates so that they do not fall off. It should also be noted that the curvature of the two bendable plastic plates is different when they are bent and moved, which should be considered during design and production: make arrangements in the structure to allow them to move in a small range without getting stuck or stuck. fall off.

For example, for a certain LED lighting tube, under the condition of not considering the movement, a round hole is opened on the front plastic plate. The shoulder portion is clamped between two plastic plates, and two small round holes are opened on the plastic plate at the back to allow the lead wires of the lamp tubes to pass through.

In the case of considering the movement, it is assumed that during the bending process, for a certain lamp tube, there is only lateral movement between the front and rear plastic plates where it is located, and no longitudinal movement, then it can be designed and produced. Consider changing the above-mentioned round hole into a horizontal slot hole, so that when the front and rear plastic plates move relative to each other, the lamp tube can also move in the slot hole. The movement of other pipes and other directions can be handled by analogy.

The three methods introduced above can make the installation board bendable.

In the utility model, the two ends of the mounting plate are connected with the side wall of the machine body by a sliding hinge structure. The sliding hinge structure characterizes the nature and status of the connection: relative to the side wall of the body, both ends of the mounting plate can have sliding displacement and angle changes.

An advancing and retreating mechanism is arranged on the mounting plate, and the function of the advancing and retreating mechanism is to make the mounting plate bend.

In front of the installation board is the LED lighting tube or the light-emitting part of the lamp tube; behind the installation board, an advance and retreat mechanism is set. The advancing and retreating mechanism can be pushed outwards or retreated inwards, and its active force can be designed and arranged at the central part behind the mounting plate. Of course, for specific situations, it is also possible to use other positions behind the mounting plate, including several other positions. When the advance and retreat mechanism exerts force outwards (that is, when it is forced forward), the mounting plate protrudes outward in a circular arc shape, and the LED lighting tube configured on the mounting plate expands and irradiates to the outer periphery in the normal direction, that is, the LED lighting on the mounting plate The angle of the lamp tube is rotated to expand the irradiation area; when retracted inward, the mounting plate is in an inward concave arc shape, the light of the LED lighting tube is gathered, and the light in the middle and front can be more concentrated. The above changes can adapt to the needs of different occasions. The two ends of the mounting plate are connected with the side wall of the body with a sliding hinge structure, which can ensure that the mounting plate is concave inward and protruding outward.

Description of technical solutions. It can be understood in conjunction with FIG. 1 : the mounting plate has more than two fan-shaped notches on the periphery of the circular plate, and the distance between the fan-shaped notches is the same. "Two or more" means including two. With this technical solution, when the advance and retreat mechanism at the rear of the mounting plate is pushed out or retracted inward, the small fan-shaped gaps around the circular mounting plate provide a space to be close together, so that the circular plate can protrude outward or The inner concave is curved.

Description of technical solutions. Combined with Fig. 5 and Fig. 6 to understand: the above-mentioned installation board is that two or more strip-shaped boards intersect at the center and are radially arranged at the same arrangement angle; the above-mentioned two or more strip-shaped boards are located on the same level or different level. "Two or more" means including two. The same level refers to the strip board made of one piece of material. What is drawn in Figure 6 is the situation where the strip board is on the same level. Different levels refer to the situation where the center of the strip board is superimposed, and what is drawn in Figure 5 is the situation where the strip board is superimposed at different levels. With this technical solution, when the advancing and retreating mechanism at the rear of the mounting plate is pushed out or retracted inward, the vacancy between two adjacent long strip-shaped mounting plates provides a space to be close together, so that the mounting plate can protrude outward or Concave inward to form a spherical surface.

Description of technical solutions. Understanding in conjunction with Figure 3 and Figure 4: the sliding hinge support structure is that a pair of short baffles are vertically arranged on the side wall of the lamp holder, and the edges of the mounting plate are sandwiched between two short baffles, and the short baffles The plate has a protruding length that does not fall off when the mounting plate is bent outwards or inwards to a limit position. The protruding length that does not fall off when bent to the limit position refers to the dimensional characteristics of the matching of the mounting plate and the short baffle, that is, the mounting plate will not fall out even when it reaches the limit position forward or backward. In actual implementation, attention should also be paid to leaving a larger margin as much as possible to ensure reliability. The above-mentioned structure can realize that when the mounting plate protrudes outward or is concave inward to form a spherical curved surface, the periphery of the mounting plate is connected with the side wall of the lamp holder by sliding hinges, which does not fall off to change the position, and is convenient for entering and exiting bending and changing angles.

Description of technical solutions. Understanding with reference to Fig. 1: a connecting plate is vertically arranged on the side wall of the lamp holder, and a long hole is opened on the connecting plate, and the mounting plate is pinned into the long hole of the connecting plate by pins. Obviously, the long hole provides convenience for the change of the mounting plate.

Description of technical solutions. Combined with Figure 3 and Figure 4 to understand: the advance and retreat mechanism is that a connecting block is arranged inside the mounting plate, and a push button that is pushed back and forth is arranged on the surface of the lamp holder, and the lower part of the push button extends into the lamp holder and connects with the connecting block Fixed connection, the connecting block is fixedly connected with the mounting plate. It should be noted that: the outer side of the mounting plate is the side where the tube body of the light emitting diode is located, and the opposite side of the mounting plate is the inner side. The function of the aforementioned connection block is to connect the mounting plate and the push button that is pushed back and forth, so as to keep the synchronous action of the two. When implementing the technical solution, its specific shape can be determined according to the needs of the actual situation. When the push button is moved, the outward protrusion or inward recess of the mounting plate can be changed and adjusted.

Optional technical solution: the connection block (8) is fixedly connected with the mounting plate (2), and a round hole is provided on the mounting plate (2), a screw hole is provided on the connection block (8), and screws are used to pass through Round hole, tighten in screw hole.
