[0038] Example 1
[0039] See also Figure 1 and Figure 2 The embodiment of the present invention provides a handheld warning light 100, which is particularly suitable for warning use during road vehicle maintenance, and includes a lamp body device 60 and a lamp holder device 10 installed at one end of the lamp body device 60. The lamp holder device 10 includes a mounting seat 20, a lampshade 30, a first light source module 40 and a light guide cover 50.
[0040] See also Figure 2 and Figure 3 The mounting seat 20 is a cover-shaped structure, including a housing 21 having a mounting cavity 201 and a plug-in board 22 arranged in the mounting cavity 201. The first light source module 40 is fixed in the mounting cavity 201 of the housing 21, and includes an LED substrate 41, an LED lamp bead 42 arranged on the LED substrate 41, and an annular shield 43. The LED substrate 41 provides a driving circuit for the LED lamp bead to drive the LED lamp bead to emit light. The LED lamp bead 42 is roughly arranged at the center position of the LED substrate 41, and the annular shield 43 is provided with a middle through hole. The annular shield 43 is arranged around the LED lamp bead 42, and the middle through hole is opposite to the position of the LED lamp bead 42. The LED lamp bead 42 forms a light-emitting area 401 at the middle through hole of the annular shield 43. The upper surface of the annular shield 43 is an inverted cone. The light guide cover 50 is plugged into the inner ring side wall of the annular shield 43 to form a support for the light guide cover 50. The annular shield 43 with an inverted cone surface effectively avoids blocking and loss of light.
[0041] The housing 21 has nail grooves, and the LED substrate 41 is screwed into the nail grooves of the housing 21 to fix the housing 21 and the LED substrate. It is understandable that in other embodiments, other methods such as bonding can also be used to fix the LED substrate.
[0042] The plug board 22 is arranged between the first light source module 40 and the bottom plate of the shell 21. The plug board 22 is used to achieve circuit conduction. Specifically, the plug board 22 is equipped with a positive contact 221 and at least two groups of contact pins 222. The positive contact 221 is inserted in the middle position of the plug board 22 for contacting the electrode of the battery assembly. The contact pin 222 is inserted beside the positive contact 221 for forming an electrical connection with the light source module. A window is provided in the shell 21 at a position opposite to the positive contact 221 and the contact pin 222, so that the positive contact 221 and the contact pin 222 can contact the lamp body device.
[0043] Furthermore, in one of the embodiments, a gasket 23 is provided between the plug board 22 and the LED substrate 41 to protect the LED substrate 41 and achieve heat dissipation.
[0044] The lampshade 30 is a barrel structure with an opening at the bottom, and a boss 31 adapted to the mounting seat 20 is provided at the bottom, and the lampshade 30 is plugged into the mounting seat 20 through the boss 31. The lampshade 30 forms an inner cavity 301, which irradiates the first light source module 40 and the light guide cover 50. The lampshade 30 allows light to pass through. The light emitted by the first light source module 40 is guided by the light guide cover 50 and then emitted from the lampshade 30.
[0045] See also Figure 4 and Figure 5, the light guide cover 50 is set to a transparent material, such as glass, PC material, PMMA material, etc. The light guide cover 50 has a hollow light axis hole 501, a bottom 51 and a guide portion 52. The light guide cover 50 is set on the light-emitting area 401, and the light axis hole 501 is opposite to the optical axis C of the light-emitting area 401 to ensure that the light enters the light axis hole 501 or the inside of the light guide cover 50. The bottom 51 of the light guide cover 50 is recessed inward to form a receiving area 511, and the receiving area 511 is used to receive LED lamp beads, and the inner wall of the receiving area 511 forms an incident surface 512. The guide portion 52 of the light guide cover 50 is roughly trumpet-shaped and is located at one end of the bottom 51 away from the light-emitting area 401. Part of the light generated by the first light source module 40 enters the inside of the light guide cover 50 from the incident surface 512, and the light is emitted in a direction perpendicular to the optical axis C through the guide portion 52.
[0046] In one embodiment, the bottom 51 is a columnar body with a uniform outer diameter, and the aperture D1 of the light-through axis hole 501 located at the bottom 51 remains unchanged. The aperture D2 of the accommodation area 511 of the bottom 51 is larger than D1. There is a spacing area between the accommodation area 511 and the guide portion 52. Part of the light is emitted through the light-through axis hole 501, and another part of the light enters the interior of the light guide cover 50 along the inner wall of the accommodation area 511.
[0047] The inner wall of the guide portion 52 has multiple layers of first annular inclined surfaces 521 and first annular vertical surfaces 522 that are alternately connected in sequence. The light entering the light guide cover 50 is reflected by the first annular inclined surfaces 521 and then emitted in a direction perpendicular to the optical axis C.
[0048] The outer wall of the guide portion 52 has multiple layers of alternately connected second annular slopes 523 and second annular vertical surfaces 524. The first annular slope 521 and the second annular vertical surface 524 are horizontally opposite to each other, so that the light reflected by the first annular slope 521 is emitted perpendicularly to the second annular vertical surface 524.
[0049] In one embodiment, the incident surface 512 includes a first incident surface 513 and a second incident surface 514. The first incident surface 513 is the top wall of the accommodation area 511, and the second incident surface 514 is the side wall of the accommodation area 511. The light incident from the first incident surface 513 is reflected by the first annular inclined surface 521 and then emitted in a direction perpendicular to the optical axis C, and the light incident from the second incident surface 514 is refracted in the light guide cover and then emitted in a direction inclined to the optical axis C.
[0050] By means of the specific structural design of the inner and outer walls of the light guide cover 50 , the light is refracted inside the light guide cover 50 and then reflected by the first annular inclined surface 521 , so that the light emission angle reaches 180°.
[0051] Specifically, the cross section of the guide portion 52 is circular or regular polygonal. Preferably, the cross section of the guide portion 52 is a regular polygon, and the number of sides of the regular polygon is not less than 3. For example, it can be a regular quadrilateral, a regular pentagon, a regular polygon, etc. Figure 6 and Figure 7 In this embodiment, the cross section of the guide portion 52 is a regular octagon, and correspondingly, the bottom portion 51 is an octagonal structure, and the middle through hole of the annular shield 43 is a matching regular octagonal structure. Compared with a circular cross section, a structure designed as a regular polygon can achieve a better light aggregation effect and a higher luminous intensity.
[0052] In one embodiment, the inclination angle α between the first annular inclined surface and the horizontal plane is 30° to 45°, and more preferably, the inclination angle α is 33° to 41°.
[0053] In one embodiment, the adjacent first annular slope 521 and the adjacent second annular slope 523 have the same inclination angle.
[0054] In one embodiment, along the light emitting direction of the light-through axis hole 501, the lengths of the plurality of first annular bevels 521 increase successively, and the inclination angles decrease successively. The light guide cover 50 is trumpet-shaped, with a large opening at the top end and a small opening at the bottom end. From the bottom end to the top end, the lengths of the first annular bevels 521 increase successively, and the inclination angles decrease successively. Similarly, from the bottom end to the top end, the lengths of the second annular bevels 523 increase successively, and the inclination angles decrease successively. With this design, more light can be reflected on the first annular bevels 521.
[0055] In one embodiment, the first annular inclined surface 521 is a total reflection surface. Further preferably, a reflective film is coated on the inner side wall of the light guide cover 50 .

[0057] The end of the lamp body device 60 away from the lamp head device 10 is provided with a light-through area 601, and a second light source module 61 is provided in the light-through area 601. The second light source module 61 includes a light source board 611, a lens 612 and a reflective cup 613 installed therebetween. In this embodiment, the light source board 611 is an LED light source. By arranging two groups of light sources at the head and the tail respectively, the handheld warning light can not only meet the warning needs, but also have the lighting function.
[0058] See also Figure 7 , the second light source module 61 and the first light source module 40 are powered by the same power supply assembly.

[0059] The positions of the two groups of contact pins 222 of the lamp holder device 10 are respectively matched with the positions of the inner ring contact piece 812 and the outer ring contact piece 813. The inner ring contact piece 812 contacts one group of contact pins 222, and the outer ring contact piece 813 contacts the other group of contact pins 222. The pins of the inner ring contact piece 812 are electrically connected to one of the first light source module 40 and the second light source module 61, and the pins of the outer ring contact piece 813 are electrically connected to the other light source module, so that the dry cell 602 is electrically connected to the two light source modules at the head and tail at the same time.
[0060] The barrel 70 has a cavity, and the bracket 80 is sleeved in the cavity. The bracket 80 is provided with a battery slot 801 for supporting the dry battery 602. The battery slot 801 is open at one end close to the lamp holder device 10, and is closed at the other end. Furthermore, the closed end of the battery slot 801 is provided with a side opening, and a metal spring 603 is disposed at the bottom of the dry battery 602, and the end of the metal spring 603 extends out from the side opening, so as to form a loop between the negative electrode of the dry battery and the light source module and the control board 90.

[0062] The control panel 90 is electrically connected to the first light source module 40 and the second light source module 61, respectively, and is used to control the first light source module 40 and the second light source module 61 to be turned on and off. The control panel 90 is provided with a first switch 91 for controlling the first light source module 40 and a second switch 92 for controlling the second light source module 61. The barrel 70 is provided with a key area at a position corresponding to the first switch 91 and the second switch 92. It is understandable that the opening and closing of the light source by the control panel is a prior art in the art, and will not be described in detail here.
[0063] In one embodiment, a heat sink 614 is provided on the contact surface between the light source board 611 of the second light source module 61 and the bracket 80. The heat sink 614 is L-shaped and includes a contact end in contact with the light source board 611 and an extension end extending axially toward the accommodating cavity 702 along the edge of the contact end.
[0064] The outer wall of the barrel 70 is provided with an annular recessed area 701, and the recessed area 701 is covered with a rubber coating 71. Through the provision of the rubber coating 71, the entire lamp body is effectively protected and has a good grip.
