Abstract

A light bar structure is disclosed in the present invention. The light bar structure includes a housing whereinside an accommodating space is formed, and the accommodating space is for accommodating a light unit. The light bar structure further includes a first buckling component disposed on an inner side of the accommodating space. The buckling component includes a first base disposed on a bottom inside the housing for supporting the light unit, a first arm connected to the first base and disposed on a first lateral wall inside the housing, and a first constraining portion disposed on the first arm for contacting against the light unit, so as to constrain a movement of the light unit relative to the first base.

Claims

1. A light bar structure comprising:

a housing where inside an accommodating space is formed, and the accommodating space being for accommodating a light unit, the housing comprises a protrusion disposed on a first lateral wall inside the housing; and

a first buckling component disposed on an inner side of the accommodating space, the first buckling component comprising;

a first base disposed on a bottom inside the housing for supporting the light unit;

a first arm connected to the first base and disposed on the first lateral wall inside the housing; and

a first constraining portion disposed on the first arm for engaging with the protrusion and contacting against the light unit, so as to constrain a movement of the first constraining portion and a movement of the light unit relative to the first base.

2. The light bar structure of claim 1, wherein a hole is formed on the bottom of the housing, the first buckling component further comprises an engaging portion disposed on an end of the first base for engaging with the hole.

3. The light bar structure of claim 1, wherein a direction of the first base is different from a direction of the first arm, and the first buckling component is a L-shaped structure.

4. The light bar structure of claim 1, further comprising:

a second buckling component disposed the other inner side of the accommodating space and opposite to the first buckling component, the second buckling component comprising;

a second base disposed on the bottom inside the housing for supporting the light unit with the first base;

a second arm connected to the second base and disposed on a second lateral wall inside the housing opposite to the first lateral wall; and

a second constraining portion disposed on the second arm for contacting against the light unit, so as to constrain a movement of the light unit relative to the second base.

5. The light bar structure of claim 1, wherein the first buckling component is made of conductive material for contacting an electrode of the light unit.

6. The light bar structure of claim 1, wherein the first buckling component further comprises:

a contacting portion disposed on the first base for buckling the light unit with the first constraining portion.

7. The light bar structure of claim 1, wherein an opening is formed on the bottom of the housing.

8. The light bar structure of claim 1, wherein at least one slot is formed on the first base, a plurality of sections on the first base is separated by the slot, and each section is for supporting the corresponding light unit.

9. The light bar structure of claim 8, wherein the housing comprises a block disposed on a position of the bottom adjacent to the slot on the first base.

10. A light source device comprising:

a light unit; and

a light bar structure for fixing the light unit and transmitting beams generated from the light unit to an optical plate, the light bar structure comprising;

a housing where inside an accommodating space is formed, and the accommodating space being for accommodating the light unit, the housing comprises a protrusion disposed on a first lateral wall inside the housing; and

a first buckling component disposed on an inner side of the accommodating space, the first buckling component comprising;

a first base disposed on a bottom inside the housing for supporting the light unit;

a first arm connected to the first base and disposed on the first lateral wall inside the housing; and

a first constraining portion disposed on the first arm for engaging with the protrusion and contacting against the light unit, so as to constrain a movement of the first constraining portion and a movement of the light unit relative to the first base.

11. The light source device of claim 10, wherein a hole is formed on the bottom of the housing, the first buckling component further comprises an engaging portion disposed on an end of the first base for engaging with the hole.

12. The light source device of claim 10, wherein the light bar structure further comprises:

a second buckling component disposed the other inner side of the accommodating space and opposite to the first buckling component, the second buckling component comprising;

a second base disposed on the bottom inside the housing for supporting the light unit with the first base;

a second arm connected to the second base and disposed on a second lateral wall inside the housing opposite to the first lateral wall; and

a second constraining portion disposed on the second arm for contacting against the light unit, so as to constrain a movement of the light unit relative to the second base.

13. The light source device of claim 10, wherein the first buckling component further comprises:

a contacting portion disposed on the first base for buckling the light unit with the first constraining portion.

14. The light source device of claim 10, wherein an opening is formed on the bottom of the housing, the light source device further comprises a heat dissipating plate, and the opening is filled with thermal compound, so as to dissipate heat generated by the light unit via the thermal compound and the heat dissipating plate.

15. The light source device of claim 10, wherein at least slot is formed on the first base, a plurality of sections on the first base is separated by the slot, and each section is for supporting the corresponding light unit.

16. The light source device of claim 15, wherein the housing comprises a block disposed on a position of the bottom adjacent to the slot on the first base.

17. A light bar structure comprising:

a housing whereinside an accommodating space is formed, and the accommodating space being for accommodating a light unit; and

a first buckling component disposed on an inner side of the accommodating space, the first buckling component comprising;
