US Patent 7850348: LED fixture having two illuminating ranges
US 7850348 · granted 2010-12-14
Abstract
An LED fixture having two illuminating ranges includes a lamp holder and a lamp cover. The lamp holder is arranged an illuminating module of LED lamp. The LED lamp is substantially installed downwardly with respect to the whole illuminating module, making the LED lamp project light in a downward direction. In the meantime, one side of the lamp cover is connected to the lamp holder, while another side is extended downwardly under the LED lamp. The inner face of the lamp cover is arranged as a reflecting face. One part of the light irradiated from the LED lamp is reflected by the reflecting face to form an illuminating range to project light in a forward direction of the lamp cover, while another part of light irradiated from the LED lamp without being reflected by the reflecting cover can project out of the lamp cover directly, thus that another illuminating range to project light in a downward and down-forward directions of the lamp cover is formed.

The LED lamp is substantially installed downwardly with respect to the whole illuminating module, making the LED lamp project light in a downward direction. In the meantime, one side of the lamp cover is connected to the lamp holder, while another side is extended downwardly under the LED lamp.

One part of the light irradiated from the LED lamp is reflected by the reflecting face to form an illuminating range to project light in a forward direction of the lamp cover, while another part of light irradiated from the LED lamp without being reflected by the reflecting cover can project out of the lamp cover directly, thus that another illuminating range to project light in a downward and down-forward directions of the lamp cover is formed.
Claim 1
An Light-Emitting Diode (LED) fixture having two illuminating ranges, including: a lamp holder, which is arranged an illuminating module of an LED lamp, the LED lamp beingsubstantially installed downwardly with respect to the whole illuminating module, making the LED lamp project light in a downward direction; and a lamp cover, one side of which is connected to the lamp holder, and another side of which is downwardlyextended under the LED lamp, and an inner face of which is arranged as a reflecting face, a part of the light irradiated from LED lamp projecting on the reflecting face, through a reflection by the reflecting face, an illuminating range of substantiallyparallelly reflected light projecting in a forward direction of and substantially in parallel with the lamp holder being formed, while another part of the light irradiated from the LED lamp without being reflected by the reflecting cover can project outof the lamp cover directly, thus another illuminating range to project light in a down-forward direction of the lamp cover and underneath the reflected light being formed.
Claims
16 totalAn Light-Emitting Diode (LED) fixture having two illuminating ranges, including: a lamp holder, which is arranged an illuminating module of an LED lamp, the LED lamp beingsubstantially installed downwardly with respect to the whole illuminating module, making the LED lamp project light in a downward direction; and a lamp cover, one side of which is connected to the lamp holder, and another side of which is downwardlyextended under the LED lamp, and an inner face of which is arranged as a reflecting face, a part of the light irradiated from LED lamp projecting on the reflecting face, through a reflection by the reflecting face, an illuminating range of substantiallyparallelly reflected light projecting in a forward direction of and substantially in parallel with the lamp holder being formed, while another part of the light irradiated from the LED lamp without being reflected by the reflecting cover can project outof the lamp cover directly, thus another illuminating range to project light in a down-forward direction of the lamp cover and underneath the reflected light being formed.
