Lamp assembly, lamp system, method for assembling lamp system, and method for disassembling lamp system

1. A lamp assembly, comprising:

a lamp, comprising:

a frame body having an accommodating space;

a light source assembly fixed on the frame body; and

an electrical connector assembly disposed in the accommodating space and connected to the light source assembly, wherein the electrical connector assembly comprises a first connector and a second connector, and the first connector and the second connector are connected to each other by a power wire and a signal wire; and

a connector assembly comprising an electrical connecting member, wherein the connector assembly is configured to be connected to the lamp and another lamp by the electrical connecting member,

wherein the lamp has a length L, and the connector assembly has a length P, wherein the length L of the lamp and the length P of the connector assembly satisfy the following conditions:

−8 P 2 +6 L×P− 0.9 L 2 >0.

2. The lamp assembly of claim 1 , wherein

the electrical connecting member of the connector assembly comprises a third connector and a fourth connector, and the third connector and the fourth connector are connected to each other by another power wire and another signal wire; and

the third connector of the connector assembly is electrically and signally connected to the second connector of the lamp, and the fourth connector is electrically and signally connected to the another lamp.

3. The lamp assembly of claim 2 , wherein the connector assembly further comprises an external terminal which is connected between the third connector and the fourth connector, and the external terminal is electrically and signally connected to an external device.

4. The lamp assembly of claim 1 , wherein the lamp is hung obliquely above a target object, and an included angle θ is defined between a line connecting a bottom of the lamp and a top of the target object and a vertical line, wherein the length L of the lamp, and the length P of the connector assembly, and the included angle θ satisfy the following conditions:

5. The lamp assembly of claim 1 , wherein

the connector assembly comprises a casing and a bottom cover, and the casing has an inner space, and the bottom cover is configured to open or close the inner space; and

the electrical connecting member is disposed in the inner space.

6. The lamp assembly of claim 1 , wherein the light source assembly comprises a light-emitting unit and a light guide plate, wherein the light-emitting unit is disposed in the accommodating space, the light guide plate is connected to the frame body, and a light incident surface of the light guide plate is adjacent to the light-emitting unit.

7. The lamp assembly of claim 1 , further comprising a supporting member, wherein a top surface of the lamp and a top surface of the connector assembly respectively have a groove, and one portion of the supporting member is embedded in the groove of the lamp, and the other portion of the supporting member is embedded in the groove of the connector assembly.

8. The lamp assembly of claim 1 , wherein the lamp and the connector assembly respectively have a suspension member.

9. A lamp system, comprising at least two lamps and at least one connector assembly of claim 1 .

10. The lamp system of claim 9 , wherein

the first connector of an endmost one of the lamps is connected to an external power source; and

the electrical connector assembly of each of the rest of the lamps is connected to the electrical connecting member of its adjacent connector assembly so as to form a connection with the endmost one of the lamps.

11. A method for assembling a lamp system, comprising:

providing a lamp system of claim 9 ;

hanging suspension members located on two opposite ends of a main lamp of the lamps to a ceiling, wherein the first connector of the electrical connector assembly of the main lamp is connected to an external power source;

electrically and signally connecting a first end of the connector assembly to the second connector of the main lamp, and hanging a suspension member located on a second end of the connector assembly to the ceiling; and

electrically and signally connecting the first connector of a secondary lamp of the lamps to the second end of the connector assembly, and hanging a suspension member located on an end of the secondary lamp away from the connector assembly to the ceiling.

12. A method for disassembling a lamp system, comprising:

providing a lamp system of claim 9 ;

separating the electrical connector assembly of one of the lamps of the lamp system desired to be disassembled from the electrical connecting member of the connector assembly, wherein one end of the one of the lamps is fixed by a suspension member; and

separating the suspension member and the one of the lamps to remove the one of the lamps.
