Referring to fig. 1 and 3, in some embodiments, the material of the elastic member 3 may be plastic or stainless steel, and the elastic member 3 may include a body portion 31, a force applying portion 32, a first clamping portion 33, and a second clamping portion 34. The body portion 31 is an elastic sheet body, and one end of the body portion 31 is rotatably connected with the inclined plate of the light source plate 2, so that the elastic member 3 can rotate around the connection point, and the body portion 31 is tightly attached to the inner side surface of the inclined plate due to elasticity. The force application part 32 is positioned at the other end of the body part 31, and the force application part 32 protrudes towards the inner side of the light source plate 2; the force application part 32 forms an acute angle with the side surface of the light source plate 2, and the force application part 32 is provided with a through hole for facilitating the passage of fingers. The operator can pull the urging portion 32 in the direction of the projection, and the body portion 31 is released from the contact with the swash plate during this pulling due to the elasticity of the body portion 31. It can be understood that the angle between the force application portion 32 and the light source plate 2 is for the operator to pull or toggle the elastic member 3 conveniently, which may also be configured as a 90 degree protrusion, and a planar or inclined force application portion 32 is further disposed on the protrusion. It will be appreciated that the through hole may not be provided.

The first clamping portion 33 protrudes from one side of the body portion 31 and is located in front of two ends of the body portion 31, but is relatively closer to one end where the force application portion 32 is located, so that the first clamping portion 33 is conveniently pulled out of the first matching hole 22 when the force application portion 32 is applied with force. The first engagement portion 33 is engaged with the first engagement hole 22 and protrudes toward the outside of the light source plate 2 through the first engagement hole 22. The first clamping portion 33 may include a second end surface 331 and a second inclined surface 332 connected to the second end surface 331, the second inclined surface 332 is inclined from top to bottom toward the middle of the profile lamp, and the second end surface 331 is connected to the upper end of the second inclined surface 332. The second end surface 331 is configured to mate with the first end surface 111 of the limiting strip 11, so that when the first clamping portion 33 passes through the first mating hole 22, the limiting strip 11 can clamp the elastic member 3, thereby limiting the light source plate 2 from moving upward relative to the housing 1. The second inclined surface 332 is configured to cooperate with the first inclined surface 112 of the limit bar 11, and when the light source plate 2 is mounted from below, the second inclined surface 332 contacts with the first inclined surface 112, and the downward pressure applied by the operator makes the body portion 31 of the elastic member 3 contact with the inclined plate of the light source plate 2 in a close contact manner; when the light source plate 2 continues to move downwards, the first clamping portion 33 passes through the limiting bar 11, the contact between the second inclined surface 332 and the first inclined surface 112 is released, and the elastic member 3 resumes the state that the body portion 31 is tightly attached to the inclined plate. Of course, when the light source board 2 is mounted from the bottom, the force application portion 32 may be pulled manually to rotate the elastic member 3, and after the light source board 2 is mounted in place, the elastic member 3 may be rotated to a state that the first clamping portion 33 is matched with the first through hole. It will be appreciated that either of the first inclined surface 112 and the second inclined surface 332 may be provided as a vertical surface.

In some embodiments, an observation hole is formed on one side of the connection position between the body portion 31 and the first clamping portion 33, so as to facilitate observation of the matching condition between the first clamping portion 33 and the first matching hole 22. The second clamping portion 34 and the first clamping portion 33 protrude from the same side of the body portion 31, and are configured to cooperate with the second mating hole 23 to further limit the shake of the elastic member 3 relative to the light source plate 2. The second clamping portion 34 is smaller in size than the first clamping portion 33 for material saving purposes, as it is only an auxiliary limitation thereof. The body portion 31 is formed with an arc-shaped protrusion 310 at a position connected with the second clamping portion 34, and the arc-shaped protrusion 310 is located at the lower left side of the force application portion 32, so that an operator can push the arc-shaped protrusion 310 to rotate the elastic member 3 conveniently.

In some embodiments, the number of the elastic members 3 is at least three, and are respectively connected to two opposite sides of the light source plate 2. Namely, one elastic piece 3 is connected with one sloping plate, and the other two elastic pieces 3 are connected with the other sloping plate; when the number of the elastic members 3 is set to an even number of three or more, the number of the elastic members 3 connected to the two swash plates is the same.

Referring to fig. 1 to 3, the elastic member 3 is engaged with the light source plate 2 and the housing 1 to form a locking state (OFF) in which the up-and-down movement of the light source plate 2 is restricted by the stopper 11 and the elastic member 3 and an unlocking state (ON). When the light source board 2 needs to be disassembled, the light source board needs to be converted from the locked state to the unlocked state: the urging portion 32 is urged, and the first engagement portion 33 and the second engagement portion 34 are pulled out from the first engagement hole 22 and the second engagement hole 23 due to the elastic force of the body portion 31 of the elastic member 3, so that the elastic member 3 is rotated to the unlock state. Due to the elastic force of the body portion 31, in the unlocked state, the first engagement portion 33 abuts against the inside of the sloping plate of the light source plate 2 to hold the elastic member 3 in the unlocked state.

As shown in fig. 4, in some embodiments, the light extraction cover 5 may include a prismatic plate 51 and an antiglare film 52. The antiglare film 52 is fixed on the prism sheet 51, and the antiglare film 52 is closer to one side of the PCB board 4 than the prism sheet 51. The prismatic sheet 51 has a large number of prismatic particles, and can increase the light-emitting area per unit area and reduce the glare value. The material of the prismatic plate 51 includes, but is not limited to, PC, PS or PMMA material, etc. Antiglare film 52 is frosted, transparent or translucent.

The prismatic crystal plate 51 may include a plate-shaped main body 511 and a mating portion 512, wherein the mating portion 512 is connected to the lower surface of the main body 511 and is close to two side edges of the main body 511, and the mating portion 512 is spaced from the edge of the main body 511 by a distance that is adapted to the width of the receiving portion 121 of the first mounting strip 12, so that the prismatic crystal plate 51 may be lapped on the first mounting strip 12.

The fitting portion 512 may include a vertical section 5121, an outer expansion section 5122, and an inner contraction section 5123 connected in sequence, the vertical section 5121 being connected to the lower surface of the main body portion 511. The flared section 5122 is adapted to cooperate with the constriction 122 of the first mounting bar 12 to limit upward movement of the prismatic plate 51 relative to the housing 1. The inward-contraction section 5123 is connected with the outward-expansion section 5122 to form an abutment groove inside the fitting portion 512 so that both sides of the antiglare film 52 can abut on the two opposite abutment grooves. The distance between the two abutting grooves is smaller than the distance between the two side edges of the antiglare film 52, so that the antiglare film 52 is fixed to the prism sheet 51 by its own elasticity. It should be understood that the fixing manner of the antiglare film 52 and the prism sheet 51 is not limited, and the antiglare film 52 may be fixed to the prism sheet 51 by an external structure, or may be bonded to the prism sheet 51 by using a shadowless adhesive.

It is to be understood that the above examples only represent preferred embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the utility model; it should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several variations and modifications can be made without departing from the scope of the utility model; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
