| Application No. | 19211602 |
| Claim | A strip light fixture comprising: a lamp holder (100); a circuit board (200), disposed on the lamp holder (100), wherein the circuit board (200) is disposed obliquely with respect to a horizontal plane defining an illuminated surface (700); a plurality of point light sources (300), disposed on the light source mounting surface of the circuit board (200) along the length direction of the strip light fixture; a lens (400), disposed on the lamp holder (100) in a light-emitting direction of the point light source (300) for adjusting light distribution of the point light source (300) on a plane perpendicular to a length direction of the strip light fixture; wherein the strip light fixture has a symmetrical structure so that the circuit board (200) provided with a plurality of point light sources (300) is symmetrically arranged with two pieces, and correspondingly, the lens (400) is arranged with two symmetrical ones; characterized by the strip light fixture further comprising: a strip-shaped convex lens array (500), disposed on an light emitting surface or an light incident surface of the lens (400) and arranged along the length direction of the strip light fixture for converting each point light source (300) into a plurality of consecutive sub point light sources, and the sub point light source converted by the adjacent point light source (300) is connected or overlapped, wherein the lens (400) comprises a light transmission main part (401) for focusing most of the light of the point light source (300), and a light transmission secondary part (402) disposed at a certain angle with one side of the light transmission main part (401) to guide a small part of the light of the point light source (300), wherein the light transmission main part (401) projects most of the light to the distal end of the illuminated surface (700), and the light transmission secondary part (402) directs a small part of the light to the proximal end of the illuminated surface (700). The strip light fixture as claimed in claim 1, wherein the light incident surface and the light emitting surface of the lens (400) are each provided with the strip-shaped convex lens array (500). The strip light fixture according to claim 1, wherein the point light source (300) employs LED chips. The strip light fixture as claimed in claim 1, wherein the light transmission main part (401) comprises a light focusing part (4011) that guides the light to the far end of the illuminated surface (700) and a light diffusion part (4012) that guides the light to the near end of the illuminated surface (700). The strip light fixture as claimed in claim 4, wherein the curvature of the light emitting surface of the light focusing part (4011) changes from large to small in the direction from the light transmission main part (401) to the light transmission secondary part (402). The strip light fixture as claimed in claim 4, wherein the curvature of the light emitting surface of the light diffusion part (4012) changes from large to small in the direction from the light transmission main part (401) to the light transmission secondary part (402). The strip light fixture as claimed in claim 1, wherein The light transmission secondary part (402) has the effect of concentrating light, and the curvature of the light emitting surface of the light transmission secondary part (402) changes from small to large in the direction from the light transmission main part (401) to the light transmission secondary part (402). |
