The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 2 to 6, the LED light source board according to this embodiment includes a main body 1 and a light source block 4, an LED light source 5 is provided on the light source block 4, a battery and a control board are provided inside the main body 1, wing plates 2 are provided on the left and right sides of the upper surface of the main body 1, the wing plates 2 can be arranged along the length direction of the main body 1, concave portions 6 concave downward are formed between the wing plates 2, arc-shaped guide strips 3 are provided in the concave portions 6, the light source block 4 is movably sleeved on the guide strips 3, the light source block 4 is positioned at different positions on the guide strips 3 to achieve the purpose of adjusting the illumination angle by staying at different positions, and a limiting structure capable of limiting the position of the light source block 4 on the guide strips 3 is further provided on the light source block 4. This LED light source board main part 1 can produce relative movement between the light source piece 4, during the use, fix main part 1 on the head-mounted device, carry out the adjustment of illumination angle through light source piece 4 slip on gib 3, main part 1 that the in-process was equipped with the battery does not take place to remove, only light source piece 4 removes, has alleviateed moving part's weight, and then can alleviateed moving part and to limit structure produced influence, improve the accuracy of illumination angle adjustment, extension product life.

Specifically, limit structure in this LED light source board includes ejector pin 8 and adjusts pole 10, light source piece 4 has offered a link-up rectangular hole along its thickness direction, light source piece 4 has also offered a link-up rectangular hole along its length direction, two rectangular hole axes are perpendicular and crossing, adjust pole 10 set up in the rectangular hole of seting up along light source piece 4 thickness direction, adjust pole 10 tail end connection has a double-sided oblique iron 11, double-sided oblique iron 11 includes two inclined planes that set up relatively, be provided with two ejector pins 8 in the rectangular hole of seting up along light source piece 4 length direction, two ejector pins 8 are listed as the left and right both sides of adjusting pole 10, the ejector pin 8 is close to the one end of adjusting pole 10 and all is connected with single-sided oblique iron 12, be provided with a inclined plane with double-sided oblique iron 11 left side inclined plane assorted on the single-sided oblique iron 12 on the left side ejector pin 8, be provided with a inclined plane with double-sided oblique iron 11 right side inclined plane assorted on the single-sided oblique iron 12.

When the illumination angle is adjusted, the light source block 4 slides to a proper position on the guide strip 3, the double-sided chute iron 11 at the tail end of the adjusting rod 10 extrudes the single-sided chute iron 12 at the left side and the right side of the adjusting rod 10 by moving the adjusting rod 10 downwards, so that the left ejector rod 8 and the right ejector rod 8 move outwards and protrude out of the side wall of the light source block 4 and are propped against the inner side wall of the wing plate 2, and the function of limiting the position of the light source block 4 on the guide strip 3 is achieved by the friction action among the left ejector rod 8, the right ejector rod 8 and the inner side wall of the wing plate 2. In order to maintain the friction between the left ejector rod 8, the right ejector rod 8 and the inner side wall of the wing plate 2, the adjusting rod 10 can not move upwards after moving downwards in place, specifically, an elastic rubber block with the size slightly larger than that of the rectangular hole can be connected to the head end of the adjusting rod 10, after moving downwards in place, the lower part of the elastic rubber block is extruded and filled in the rectangular hole, and the elastic rubber block can not pop out of the rectangular hole without external force intervention. When the illumination angle needs to be adjusted again, the elastic rubber block is pulled out, the adjusting rod 10 is pulled upwards, the double-sided oblique iron 11 moves upwards, the left ejector rod 8 and the right ejector rod 8 move inwards under the action of the side walls of the wing plates 2 on the two sides, and then the friction effect among the left ejector rod 8, the right ejector rod 8 and the inner side walls of the wing plates 2 is relieved.

In this LED light source board, the one end that pole 10 was kept away from to ejector pin 8 all is connected with rubber head 9, and left side ejector pin 8, right side ejector pin 8 outwards move, and outstanding behind the light source piece 4 lateral wall, rubber head 9 supports the top on pterygoid lamina 2 inside wall, can increase the frictional force between left side ejector pin 8, right side ejector pin 8 and the pterygoid lamina 2 inside wall, and the limiting effect to the position of light source piece 4 on guide bar 3 is more showing.

In the LED light source plate, a limiting block 16 for limiting the separation of the double-sided chute 11 and the single-sided chute 12 is arranged at the tail end of a rectangular hole formed in the thickness direction of the light source block 4, so that the double-sided chute 11 is prevented from moving excessively to the lower side of the single-sided chute 12, and interference is caused to the follow-up upward lifting of the adjusting rod 10.

In this LED light source board, except at adjusting pole 10 head end connection elasticity glue piece, can also be provided with regulating block 15 at the rectangular hole head end of seting up along light source block 4 thickness direction, set up the screw hole that link up on the regulating block 15, adjust pole 10 threaded connection and set up on regulating block 15, adjust pole 10 tail end and be connected with two-sided oblique iron 11 through the bearing. The purpose of upward or downward movement of the adjusting rod 10 can be achieved through the rotation of the adjusting rod 10 on the adjusting block 15, the adjusting rod 10 can drive the double-sided chute 11 to synchronously move upward or downward in the moving process, and due to the fact that the bearing is arranged, the double-sided chute 11 can not be rotated together due to the rotation of the adjusting rod 10, and after the double-sided chute is moved in place, due to the threaded connection relation between the adjusting rod 10 and the adjusting block 15, the adjusting rod 10 can not automatically move under the condition that no external force is involved.

In the LED light source plate, the head end of the adjusting rod 10 is connected with the rotary handle 14, so that the adjusting rod 10 can be conveniently screwed.

In the LED light source plate, a guide sleeve 13 matched with the guide strip 3 is arranged on the lower surface of the light source block 4.

In this LED light source board, the gib 3 is provided with two, and correspondingly, light source piece 4 lower surface also is provided with two uide bushing 13, reinforcing light source piece 4 removes and connection stability.

In this LED light source board, the line groove 7 that holds that is parallel with pterygoid lamina 2 has been seted up to main part 1 upper surface intermediate position, and the electric wire between LED light source 5 on the light source piece 4 and the main part 1 upper control panel moves in holding the line groove 7 along with the slip of light source piece 4. The length of the electric wire needs to meet the requirement of the sliding stroke of the light source block 4.
