## Abstract

A strip lamp includes a strip lamp holder, provided with two light source mounting seat oppositely arranged and located on both sides of the center line; two rows of light sources, respectively arranged on the two light source mounting seats, and the light emission directions are all toward the illuminated surface and the two optical axes intersect at or near the center line; two lenses, respectively arranged on a light source mounting seat and located in the light emission direction of the corresponding light source, and both include a light entrance surface and a light emission surface. The shielding of the light source mounting seats on the opposite side of the light source reduces glare, on the one hand, the setting of the light shield is reduced and the light output efficiency is improved. On the other hand, the strip lamp also has a better anti-glare effect.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The strip lamp as claimed in claim 1, wherein an included angle between the optical axis (301) and the center line (101) is in the range between 50° and 80°.

### Claim 3 (depends on 1)

The strip lamp as claimed in claim 1, wherein the light emission direction of maximum intensity of the light emitted from the light source (300) after passing through the corresponding lens (400) is defined as a light distribution optical axis (403), and an included angle between the light distribution optical axis (403) and the center line (101) is in a range between 60° and 85°.

### Claim 4 (depends on 3)

The strip lamp as claimed in claim 3, wherein an extension line of the light distribution optical axis (403) is located above a top edge of the light source mounting seat (102) on the opposite side.

### Claim 5 (depends on 3)

The strip lamp as claimed in claim 3, wherein the included angle between the light distribution optical axis (403) and the center line (101) is in the range between 70° and 85°.

### Claim 6 (depends on 1)

The strip lamp as claimed in claim 1, wherein the light from the light source (300) is refracted and distributed on the light entrance surface (401) and the light emission surface (402).

### Claim 7 (depends on 1)

The strip lamp as claimed in claim 1, wherein the light emission surface (402) comprises a first light focusing part (4021) and a second light focusing part (4022), and
the first light focusing part (4021) causes the blocked light of the light source (300) to be refracted and to cross the top edge of the light source mounting seat (102) on the opposite side thereof, and is located on a side of the light distribution optical axis (403) away from the surface (200) to be illuminated; and focuses the light corresponding to the light source (300) to the light distribution optical axis (403);
the second light focusing part (4022) is located on a side of the light distribution optical axis (403) close to the surface (200) to be illuminated, and focuses the light corresponding to the light source (300) to the light distribution optical axis (403).

### Claim 8 (depends on 7)

The strip lamp as claimed in claim 7, wherein the light emission surface (402) further comprises a diffusion part (4023) connected to one end of the second light focusing part (4022) away from the light distribution optical axis (403).

### Claim 9 (depends on 1)

The strip lamp as claimed in claim 1, wherein the light entrance surface (401) is recessed toward the light emission surface (402).

### Claim 10 (depends on 1)

The strip lamp as claimed in claim 1, wherein the lens (400) is a strip lens extending along the length direction of the strip light holder (100).

### Claim 11 (depends on 1)

The strip lamp as claimed in claim 1, wherein the light source (300) comprises a plurality of point light sources arranged at intervals along the length direction, and the lenses (400) are each a single lens provided corresponding to each point light source.

### Claim 12 (depends on 1)

The strip lamp as claimed in claim 1, wherein
the light source (300) comprises a plurality of point light sources arranged at intervals along the length direction, and
the lenses each comprise a mounting board (404) extending along the length direction of the strip light holder (100) into which multiple single lenses are integrated, each of the single lenses being associated with a corresponding light source (303) of the associated row of light sources (300) and each of the single lenses comprising a light entrance surface (401) and a light emission surface (402).

### Claim 13 (depends on 1)

The strip lamp as claimed in claim 1, further comprising a lampshade (500) arranged on the strip lamp holder (100) and located outside the lens (400).
