Description

LED lighting

The invention relates to the field of illumination, and in particular to an LED illumination lamp.

With the increasing awareness of environmental protection around the world, LED lighting has been rapidly developed in the field of indoor lighting. The existing table reading lighting fixtures are mainly table lamps. Generally, the luminous surface of the table lamp is about 400mm from the height of the tabletop. It is closer to the user's eye level, and has a certain sense of oppression in the space. The light of the existing LED table lamp is directly directed to the environment. If the person directly looks at the LED with the eye. When the lamp is on, glare will occur.

In view of this, it is necessary to provide an anti-glare LED illumination lamp.

The technical solution adopted by the invention is: an LED illumination lamp for illuminating a specific area on a plane or a desktop, comprising a bracket body and an LED light source, the bottom surface of the bracket body being fixed relative to the plane or table to be illuminated, the LED light source Provided on a side of the bracket body, the LED light source is disposed toward the plane or a specific area on the desktop, and further includes a hood fixed to the bracket body, the hood being located above the LED light source, the hood One end of the hood is connected to the side surface, and the other end of the hood is spaced apart from the side surface, and the hood is configured to block light emitted from the LED light source deviating from the specific area.

Compared with the prior art, the LED illumination lamp has an LED light source disposed on a side of the bracket and disposed toward a specific area on the plane or the desktop, and is disposed above the LED light source for shielding from the LED light source. A hood that deviates from the light of the particular area such that light can be concentrated on the particular area, and the light from the LED source does not directly illuminate the human eye, thereby avoiding glare.

Is a perspective view of the first embodiment of the LED lighting lamp of the present invention;

Is a sectional view of the LED lighting shown in Figure 1;

Is a schematic diagram of the optical path of the LED lighting shown in FIG. 2;

The invention is described in detail below by way of specific examples:

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a first embodiment of an LED illuminator of the present invention for illuminating a particular area on a flat or table top. The LED illuminator comprises a bracket body 10 and an LED light source 20, the bottom surface of which is fixed relative to the plane or table to be illuminated. The LED illuminator further includes a battery (not shown) disposed within the cradle body 10 for powering the LED light source 20.

Referring to FIG. 1 and FIG. 2 , the bracket body 10 is made of a heat dissipating material, and the LED light source 20 is thermally connected to the bracket body 10 . During operation, heat generated by the LED light source 20 will be dissipated through the bracket body 10 . The LED light source 20 is disposed on a side 11 of the holder body 10, the LED light source 20 being disposed toward the plane or a specific area on the table top. In this embodiment, a plurality of LED light sources 20 are included, and the LED light sources 20 are arranged in a strip shape.

Referring to FIG. 1 to FIG. 3 , the LED illuminator further includes a hood 30 fixed to the bracket body 10 , the hood 30 is located above the LED light source 20 , and one end of the hood 30 and the side surface 11 is connected, and the other end of the hood 30 is spaced apart from the side surface 11. The hood 30 is mainly used to block light emitted from the LED light source 20 that deviates from the specific area. In this embodiment, the hood 30 is integrally formed from the top of the side surface 11 of the bracket body 10, and the hood 30 has a "door"-shaped bending structure. The height of the other end of the hood 30 on the plane or table top is lower than the height of the LED light source 20 on the plane or table top. The LED light source 20 and the other end of the hood 30 constitute a reference surface, and the angle between the reference surface and the plane or the table top is an obtuse angle. In fact, by adjusting the height of the other end of the hood 30 on the plane or the table top, the illumination area of the LED illuminator, that is, the size of the particular illumination area, can be changed. However, the height of the other end of the hood 30 on the plane or table top is lower than the height of the LED light source 20 on the plane or the table top. Otherwise, a specific area cannot be formed on the plane or the table top. The hood 30 forms a first reflecting surface 31 facing the inner side wall of the LED light source 20, and the first reflecting surface 31 is for reflecting the light emitted by the LED light source 20. The side surface 11 of the bracket body 10 forms a second reflecting surface 12, and the second reflecting surface 12 is disposed corresponding to the first reflecting surface 31 for reflecting light toward the second reflecting surface 12, the second The reflective surface 12 is used to reflect light toward a particular area of the plane or table top. The second reflecting surface 12 is a curved surface structure extending integrally from the plane or the table top. The angle between the tangent plane of the second reflecting surface 12 and the plane or the table top is from the bottom of the second reflecting surface toward the LED light source 20 . The position is gradually reduced. The purpose of this setting is to make the light shine more on a specific area and prevent the light from reflecting upward.

Referring to FIG. 2, a lens 40 is also included, which is disposed corresponding to the LED light source 20 for concentrating the light emitted by the LED light source 20.

In summary, the LED illumination lamp is disposed on the side 11 of the bracket 10 and disposed toward a specific area on the plane or the desktop, and is disposed above the LED light source 20 for shielding the LED light source. 20 emits a hood 30 that deviates from the light of the specific area, so that light can be concentrated on the specific area, and the light emitted by the LED light source 20 does not directly illuminate the human eye, thereby avoiding glare generation. .

In addition, the hood 30 of the LED illuminator forms a first reflecting surface 31 toward the inner side wall of the LED light source 20, and the side surface 11 of the bracket body 10 is disposed with the second reflecting surface 12 corresponding to the first reflecting surface 31. The LED light source 20 Light rays deviating from the specific area are sequentially irradiated to the specific area to be illuminated by the reflection of the first reflecting surface 31 and the second reflecting surface 12, thereby increasing the utilization of light and improving the lighting effect.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalents, improvements, etc., which are made within the spirit and principles of the present invention, should be included in the present invention. Within the scope of protection.
