Strip lamp

A strip lamp comprising a strip lamp holder (100), two rows of light sources (300) and two lenses (400), wherein:

• the strip lamp holder (100) has a center line (101) perpendicular to a surface (200) to be illuminated in a plane perpendicular to its length direction, and the strip lamp holder (100) is provided with two light source mounting seats (102) oppositely arranged and located on opposite sides of the center line (101);
• each of the two rows of light sources (300) is respectively arranged on the light source mounting seat (102), so that light emission directions of the two rows of light sources (300) are all toward the surface (200) to be illuminated and so that two optical axes (301) of the two rows of light sources intersect at or near the center line (101);
• and
• each of the two lenses (400) is respectively arranged on the light source mounting seat (102) and located in the light emission direction of the corresponding light source (300), and each of the two lenses (400) includes a light entrance surface (401) and a light emission surface (402);
• wherein,
• the light from the light source (300) comprises a blocked light extending to below a top edge of the light source mounting seat (102) on the opposite side thereof, and a part of the light emission surface (402) away from the surface (200) to be illuminated causes the blocked light of the light source (300) to be refracted and then cross the top edge of the light source mounting seat (102) on the opposite side.
