Description

Lamp

The invention relates to a luminaire.

Fluorescent lamps are widely used in various lighting applications as a light source device closest to natural light. However, the light emitted by ordinary fluorescent lamps is generally non-directional, so the illumination range of the fluorescent lamps cannot be adjusted, so that some light is scattered to some unnecessary. Where the illumination is caused, the waste of energy or the influence of others is not conducive to saving energy and causing light pollution.

In view of this, it is necessary to provide a luminaire that can adjust the range of light illumination.

A luminaire includes a lamp holder and a line type light source. The luminaire further includes two reflecting plates and two pivoting devices, and the reflecting plates are respectively rotatably disposed on two sides of the lamp holder by two pivoting devices. The linear light source is disposed in a space surrounded by the lamp holder and two reflective plates, the reflective plate includes a reflective surface opposite to the linear light source, the reflective plate being parallel to the linear light source The axis of the pivoting device is pivoted such that its reflecting surface rotates in a direction toward or away from the linear light source.

Compared with the prior art, the present invention adopts a rotatable reflecting plate on both sides of a lamp holder of a common lamp, and uses the reflecting plate to reflect the light emitted by the fluorescent lamp into a specific area and range to realize directional illumination. Increased light utilization while reducing light pollution.

Referring to FIG. 1 and FIG. 2 , the lamp 100 of the first preferred embodiment of the present invention includes a lamp holder 110 , a linear light source 130 , two reflective plates 140 , and two pivoting devices 150 . The two reflective plates 140 are connected to the two sides of the socket 110 by the pivoting device 150. The linear light source 130 is disposed in a space surrounded by the socket 110 and the reflector 140. Inside. The reflector 140 is parallel to the axis of the linear light source 130 and rotates in a direction of approaching or facing away from the linear light source 130 with the pivoting device 150 as an axis.

The lamp holder 110 is a frame supporting the lamp 100, and has a bottom surface 112 and two side walls 114 connected to the bottom surface 112. At least one of the side walls 114 is formed with at least one protrusion. The bump 116 of the sidewall 114 defines a through hole (not shown) parallel to the sidewall 114 and the bottom surface 112.

It can be understood that the bumps 116 may also be plural and evenly distributed on the sidewalls 114.

The at least one reflecting plate 140 is a specular reflecting device, and includes a reflecting surface 142 and two side surfaces 144. At least one of the protrusions 116 on the side wall 144 of the lamp holder 110 is open on at least one of the side surfaces 144. The groove 146 defines a through hole 148 parallel to the extending direction of the side surface 144 on the reflection plate 140 on both sides of the groove 146. Preferably, a plurality of grooves 146 are formed on a plurality of protrusions 116 on one side 144 of the side wall 114 of the socket 110, and the plurality of protrusions 116 can be respectively received in the In the groove 146. The reflector 140 is rotatably disposed on the sidewall 114 of the socket 110 by the pivoting device 150, and the recess 146 receives the socket. a bump 116 of the 110, the pivoting device 150 extends through the through hole of the bump 116 and the through hole 148 of the reflecting plate 140, and the reflecting plate can pivot the device 150 to make the reflecting surface thereof 142 is rotated in a direction toward or away from the linear light source 130.

In use, the position of the reflecting plate 140 can be adjusted as needed, so that the light is reflected by the reflecting plate 140 to the desired irradiation place, so that the light irradiation range and direction of the lamp 100 can be conveniently controlled.

It can be understood that the luminaire 100 can further include at least one base 120 disposed at one end of the bottom surface 112 of the socket 110 for supporting the linear light source 130 and providing power to the associated linear light source 130.

It can be understood that the reflector 140 can also be rotatably disposed on the socket 110 of the lamp 100 by screwing the two ends of the reflector 140. On the side wall 114.

It can be understood that the end wall of the bump 116 of the socket 110 can be provided with a plurality of recesses 115 distributed along a circular trajectory concentric with the through hole 118. A through hole 143 corresponding to the recessed hole 115 is defined in the end of the reflective plate 140. The through hole 143 is provided with a pin 145. One end of the pin is received in the through hole 143, and the other end is accommodated in the hole 143. In the recess 115 of the socket 110, when the pin 145 is first aligned with the next or another 115 recess when adjusting the position of the reflector 140, the pin 145 is inserted into the recess 115. Positioning.

Referring to FIG. 3, the state of use of the luminaire 100 of the present invention rotates the reflector 140 to a direction of the linear light source 130, so that the light emitted by the linear light source 130 can be controlled within a certain range. Directional lighting.

The invention adopts a rotating reflector on the side of the lamp holder of the ordinary lamp, and uses the reflector to reflect the light emitted by the fluorescent lamp to a specific area and range to achieve directional illumination, thereby improving the utilization of light, and at the same time Reduce the purpose of light pollution.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
