Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to an eye-protection LED desk lamp. Background Art

[0002] Table lamps generally refer to electric lamps with bases that are placed on tables. However, with the advancement of technology, the appearance and shape of table lamps are constantly developing, and various styles of table lamps have gradually appeared. Table lamps are relatively small and exquisite, and easy to carry.

[0017] The following is a further detailed description through specific implementation methods:

[0018] like Figures 1 to 3 As shown:

[0019] An eye-protection LED desk lamp comprises a base 1, a connecting bracket 2, a lamp body and a control unit. The control unit is installed in the base 1. The connecting bracket 2 is used to support the lamp body and to install the lamp body on the base 1. The lamp body is electrically connected to the control unit. The control unit is an existing mature technology and is used to control the operation of the lamp body. The control unit comprises a main control board and an adjusting knob. The main control board is installed in the base 1 and is used to control the operation of the lamp body. The adjusting knob is installed on the base 1 and is used to operate the lamp body.

[0020] The lamp body includes an outer lampshade 3, a first light-emitting module, a plurality of second light-emitting modules and a light-transmitting plate 11. The top of the outer lampshade 3 is hinged to the connecting bracket 2, so that the lamp body can swing on the connecting bracket 2. The light-transmitting plate 11 is installed at the bottom of the outer lampshade 3. The surface of the light-transmitting plate 11 is a frosted structure, so that the light it emits is more uniform and soft. The first light-emitting module and each second light-emitting module are installed in the outer lampshade 3, and the first light-emitting module is located at the inner top of the outer lampshade 3.

[0021] The first light-emitting module includes an LED lamp board 5, a plurality of light guide columns 6 and a first light guide plate 7. The LED lamp board 5 is fixedly mounted on the top of the outer lamp cover 3. A plurality of LED lamp beads are evenly arranged on the LED lamp board 5. The LED lamp beads are light sources. The first light guide plate 7 is fixedly mounted in the outer lamp cover 3 and the LED lamp beads are connected to the first light guide plate 7 through a plurality of light guide columns 6. One end of the light guide column 6 abuts against the LED lamp beads, and the other end of the light guide column 6 is fixedly mounted on the first light guide plate 7. The light guide column 6 can transmit the light emitted by the LED lamp beads to the first light guide plate 7. The light guide column 6 and the first light guide plate 7 are integrally formed so that the light guide column 6 can better transmit the light to the first light guide plate 7. The bottom of the first light guide plate 7 is evenly distributed with a plurality of hemispherical light guide protrusions 8. The light guide protrusions 8 can refract the light and then evenly distribute the light, so that the first light guide plate 7 can evenly irradiate the light to each second light guide module;

[0022] Each second light-emitting panel module is evenly installed on the outer lamp cover 3 and each second light-emitting module is separated in pairs. The second light-emitting module includes a second light guide plate 9 and an LED lamp tube 10. LED lamp tubes 10 are embedded at both ends of the second light guide plate 9 so that the light of the LED lamp tube 10 can be irradiated into the second light guide plate 9.

[0023] A reflective film 4 is installed on the inner side of the outer lampshade 3 , and the reflective film 4 can reflect light to each second light guide plate 9 , thereby making the light at the second light guide plate 9 brighter.

[0024] The specific implementation process is as follows:

[0025] When using the eye-protection LED desk lamp, the brightness of the desk lamp can be turned on and adjusted by adjusting the knob. The main control board controls the LED light board 5 and the LED light tube 10 to start. The LED lamp beads at the LED light board 5 emit light and transmit it to the first light guide plate 7 through the light guide column 6. Then, the hemispherical protrusions at the bottom of the first light guide plate 7 can refract the light in the first light guide plate 7, so that the light emitted from the first light guide plate 7 is evenly irradiated to each second light guide module; the LED light tubes 10 at both ends of the second light guide module irradiate the light to the second light guide plate 9. At the same time, since a plurality of light guide channels 12 are evenly arranged in the second light guide plate 9, more light is concentrated on the second light guide plate 9, and the light is more evenly irradiated on the light-transmitting plate 11. At the same time, the reflective film 4 on the inner side of the outer lampshade 3 can concentrate and reflect the light in the outer lampshade 3 to each second light guide plate 9. Then, each second light guide plate 9 cooperates to transmit the light to the light-transmitting plate 11, so as to evenly and softly irradiate the outside.

[0026] The eye-protection LED desk lamp emits uniform and soft light through the first light-emitting module to illuminate the second light-emitting modules. The LED light panels 5 of the second light-emitting modules illuminate the second light guide plate 9. The reflective film 4 reflects the light to the second light guide plate 9. Through the coordinated action of the second light guide plates 9, the light can be evenly and softly diffused to the light-transmitting plate 11, thereby making the light irradiated by the desk lamp to the outside world more uniform and soft, reducing the glare of the light, effectively protecting the user's eyes, and meeting the user's usage needs.
