Detailed Description

In the related art, an illumination device using an LED light source can emit illumination light to provide illumination for a user, so as to meet the light requirements of the user on scenes such as office work and study. For example, the light emitted by the lighting device may be directed downward in a vertical direction toward the work surface. The light emitted by the LED light source in the lighting device only comprises a partial wave band in the visible light range, so that the lighting light emitted by the LED light source is in a missing state in the partial wave band, and the spectrum of the lighting light emitted by the LED light source is different from that of the natural light. When a user uses the illumination device for a long time, there is a possibility that the illumination light emitted from the LED light source adversely affects the eyesight of the user.

In order to solve the technical problems, the eye-protecting lighting device provided by the embodiment of the utility model comprises a light-emitting component and a light-transmitting component. The light-transmitting member is for transmitting light. The light-transmitting component is arranged on the light transmission path of the light. The illumination light emitted by the light emitting assembly can pass through the light transmitting component along the propagation light path. Quantum dot particles are arranged in the light-transmitting component. The light emitted by the light emitting component can excite the quantum dot particles so that the quantum dot particles generate compensation light. The wavelength band of the compensation light is 700 nm to 820 nm. The compensation light can supplement the defect of the spectrum of the illumination light rays emitted by the light-emitting component in the wave band range of 700-820 nanometers, so that the spectrum of the light rays emitted by the illumination device is more similar to the spectrum of natural light rays (also called solar spectrum), thereby being beneficial to improving the comfort of users, effectively reducing the possibility of generating eyestrain, being beneficial to protecting the eyesight of the users and being beneficial to preventing and controlling myopia.

Fig. 1 schematically shows the structure of an eye-protecting illumination device 10 according to an embodiment of the present utility model. Fig. 2 schematically shows a partial cross-sectional structure of an eye-shielding illumination device 10 according to an embodiment of the present utility model. Fig. 3 is an enlarged view at W in fig. 2.

In some implementations, referring to fig. 1-3, an eye-shielding lighting device 10 can include a light emitting assembly 20, a light transmissive member 30, and a light head 50. The light emitting assembly 20 and the light transmitting member 30 may be provided to the base 50. The light emitting assembly 20 provided on the lamp cap 50 can emit light. For example, the light emitted by the light emitting component 20 can be directed downward to the working surface along the vertical direction after passing through the light transmitting component 30, so as to meet the light demands of the office, learning and other scenes.

The eye-shielding lighting device 10 further comprises a lamp base 60 and a lamp post 70 connected. The lamp base 50 is connected to a lamp post 70. The lamp socket 60 may be placed on the ground. The lamp socket 60 is used to provide a supporting force for the whole eye-protecting lighting device 10 to keep the whole eye-protecting lighting device 10 stable. The lamp post 70 is used to connect the lamp socket 60 and the lamp cap 50. Illustratively, the height of the lighthead 50 may be adjusted by a lightpost 70.

The lamp socket 60 has a relatively large projected area in the vertical direction so that the lamp socket 60 can be relatively stably placed on a support platform (e.g., the ground) to provide good support to the eye-shielding lighting device 10 as a whole. One end (i.e., a lower end) of the lamp post 70 may be connected to the lamp socket 60. For example, the light pole 70 and the light holder 60 may be detachably connected to each other for easy assembly and disassembly. The lamp cap 50 may be connected to the other end (i.e., upper end) of the lamp post 70. For example, the base 50 may be removably coupled to the light pole 70 for ease of assembly and disassembly.

Illustratively, the lamp cap 50 includes a lower light exit surface. The light head 50 can emit light downwards through the lower light emitting surface for illuminating the lower working surface, for example, illuminating the lower office desk surface, so as to provide illumination for the working surface as required.

Illustratively, the light emitting assembly 20 and the light transmissive member 30 may be disposed inside the lamp cap 50. The light emitting element 20 can be turned on and emit light in an energized state. The light-transmitting member 30 serves to transmit light. The light-transmitting member 30 is disposed on the light propagation path S of the light emitted from the light-emitting component 20, that is, the light emitted from the light-emitting component 20 needs to pass through the light-transmitting member 30 and then be emitted from the eye-protection lighting device 10 to the external environment.

The light emitting assembly 20 includes a circuit board 21 and white LED beads 22. One or more white LED beads 22 may be disposed on one circuit board 21, which is not particularly limited in the present utility model. The circuit board 21 may be a printed circuit board (printed circuit board, PCB) or a flexible circuit board (flexible printed circuit board, FPCB). The white LED lamp bead 22 has conductive pins (not shown). The white LED lamp beads 22 are electrically connected to the circuit board 21 through conductive pins. One white LED light bead 22 may include two conductive pins, with one conductive pin acting as the negative electrode and the other conductive pin acting as the positive electrode. The white LED lamp bead 22 has a first light emitting surface 22a. Light generated by the white LED lamp beads 22 in the energized state can exit through the first light-emitting surface 22a. The light emitted by the white LED lamp beads 22 in the energized state is visually white. The circuit board 21 and the first light-emitting surface 22a are arranged at intervals, that is, a space is reserved between the circuit board 21 and the first light-emitting surface 22a, so that the circuit board 21 completely avoids leaving the first light-emitting surface 22a, the circuit board 21 is prevented from blocking the light emitted from the first light-emitting surface 22a, and the light-emitting efficiency of the first light-emitting surface 22a of the white light LED lamp bead 22 is improved.

The light-transmitting member 30 includes a light-entering surface 30a and a second light-exiting surface 30b disposed opposite to each other. On the propagation light path S, the light incident surface 30a is disposed near the first light emergent surface 22a, and the second light emergent surface 30b is far from the first light emergent surface 22a. The light emitted from the first light emitting surface 22a of the white LED lamp bead 22 may be incident on the light incident surface 30a of the light transmitting member 30 along the propagation light path S. The light enters the light-transmitting member 30 from the light-entering surface 30a and continues to propagate toward the second light-exiting surface 30b inside the light-transmitting member 30. Finally, the light exits from the second light exit surface 30b of the light-transmitting member 30.

The light-transmitting member 30 is provided with quantum dot particles 40. The quantum dot particles 40 are disposed in a region between the light-incident surface 30a and the second light-emitting surface 30b. The light-transmitting member 30 encapsulates the quantum dot particles 40, that is, the quantum dot particles 40 are located inside the light-transmitting member 30 and are not exposed to the light-incident surface 30a and the second light-emitting surface 30b of the light-transmitting member 30. When the quantum dot particles 40 are in direct contact with elements such as moisture and oxygen in the air, the elements such as moisture and oxygen adversely affect the light emission stability of the quantum dot particles 40. In the embodiment of the utility model, the light-transmitting component 30 coats the quantum dot particles 40, so that the light-transmitting component 30 can form a protective layer outside the quantum dot particles 40, effectively prevent elements such as moisture and oxygen in the air from directly contacting the quantum dot particles 40 with the elements such as moisture and oxygen in the air, and effectively ensure the luminous stability of the quantum dot particles 40.

The light emitted from the white LED beads 22 enters the light-transmitting member 30 and the light emitted from the white LED beads 22 is used to excite the quantum dot particles 40, so that the quantum dot particles 40 generate the compensation light. The wavelength band of the compensation light is 700 nm to 820 nm. In the embodiment of the present utility model, the wavelength band of the light emitted from the white LED lamp bead 22 may be 380 nm to 700 nm.

In some implementations, the material of the light transmissive member 30 may include, but is not limited to, glass, plastic, or resin. Quantum dot particles 40 are nano-scale semiconductor crystal particles. By applying a certain light pressure to such quantum dot particles 40, the quantum dot particles 40 can emit light of a predetermined wavelength band. Illustratively, the quantum dot particles 40 may have a diameter ranging from 2 nanometers to 10 nanometers. Illustratively, the material of the quantum dot particles 40 includes cadmium arsenide (CdSe). In some examples, the quantum dot particles 40 are dispersed into a material used to form the light transmissive member 30, and the light transmissive member 30 including the quantum dot particles 40 is formed by extrusion or injection molding.

The eye-protecting lighting device 10 of the embodiment of the present utility model includes a light emitting assembly 20 and a light transmitting member 30. The light emitting assembly 20 includes white LED beads 22. The light emitted from the white LED beads 22 may pass through the light-transmitting member 30 and then be transmitted out of the light-transmitting member 30. Because the quantum dot particles 40 are disposed in the light-transmitting member 30, after the light emitted by the white LED lamp beads 22 enters the light-transmitting member 30, the light emitted by the white LED lamp beads 22 can excite the quantum dot particles 40, so that the quantum dot particles 40 generate the compensation light with the wave band of 700 nm to 820 nm. The light finally exiting the light-transmitting member 30 may include the light emitted from the white LED beads 22 and the compensation light generated by the quantum dot particles 40. The compensation light with the wave band of 700-820 nanometers generated by the quantum dot particles 40 can be used for supplementing the spectrum deficiency of the light emitted by the white light LED lamp beads 22 in the wave band of 700-820 nanometers, so that the spectrum of the eye-protection lighting device 10 is more similar to the natural light spectrum (also called solar spectrum), the comfort level of a user is improved in the process of using the eye-protection lighting device 10, the possibility of eye fatigue of the user is effectively reduced, the eyesight of the user is protected, and myopia prevention and control are facilitated.

Referring to fig. 3-5, the eye-shielding illumination device 10 further includes a light guide assembly 80. The light guide assembly 80 can receive the light emitted from the white LED lamp beads 22 and is used for changing the propagation direction of the light, so that the light emitted from the white LED lamp beads 22 can reach the light-transmitting component 30. In the embodiment of the present utility model, the light guide assembly 80 includes a reflection plate 81 and a light guide plate 82. The reflection plate 81, the light guide plate 82, and the light transmitting member 30 are stacked in the thickness direction of the reflection plate 81. The light guide plate 82 is located between the reflective plate 81 and the light transmitting member 30. The white LED beads 22 are positioned at one side of the light guide assembly 80 in a direction perpendicular to the thickness direction, so that the white LED beads 22 emit light in a side-emitting form. For example, the thickness direction of the reflection plate 81 is the same as the vertical direction. Along the horizontal direction, the white LED light beads 22 are located at one side of the light guide assembly 80. The light guide assembly 80 and the light transmitting member 30 are disposed at intervals from the white LED beads 22.

The light emitted from the white LED beads 22 may enter the light guide plate 82, and then the light may change a propagation direction under the reflection of the reflection plate 81 to propagate toward the light transmitting member 30 at one side of the light guide plate 82. The light-transmitting member 30 may have a function of diffusing light so that the light exiting from the light-transmitting member 30 is more uniform and gentle.

In some examples, the light transmissive member 30 is a plate-like structure. Illustratively, the white LED light beads 22 are located on one side of the light guide assembly 80 in the horizontal direction. In the vertical direction, the light transmitting member 30 is located below the light guide assembly 80. Light emitted from the white LED beads 22 enters the light guide plate 82 in the horizontal direction. The reflection plate 81 reflects the light emitted from the white LED beads 22 so that the light emitted from the white LED beads 22 enters the light-transmitting member 30 in the vertical direction. Illustratively, the light-transmitting member 30 may be a diffusion plate having a function of diffusing light.

In some examples, the eye-shielding lighting device 10 further includes a housing 90. The housing 90 has light holes 91. The light emitting assembly 20, the light guiding assembly 80 and the light transmitting member 30 are all disposed within the housing 90. The second light emitting surface 30b of the light transmitting member 30 is disposed facing the light transmitting hole 91, so that the light emitted from the second light emitting surface 30b can be transmitted to the external environment through the light transmitting hole 91. Illustratively, the lower surface of the housing 90 is provided with light holes 91 in the vertical direction. Illustratively, the lamp head 50 includes a housing 90. Illustratively, the material of the housing 90 may be metal or plastic. Illustratively, the light transmissive member 30 is coupled to the housing 90, e.g., the light transmissive member 30 is bonded to the housing 90. The light-transmitting member 30 and the housing 90 have overlapping areas, preventing the light-transmitting member 30 from falling out of the light-transmitting hole 91.

Fig. 7 schematically illustrates a partially exploded structure of the eye-shielding illumination device 10. Fig. 8 schematically shows a partially cut-away configuration of the eye-shielding illumination device 10. Referring to fig. 6-8, the eye-shielding lighting device 10 further includes a housing 100 and a base 140. The eye-shielding lighting device 10 may be secured to a mounting surface (e.g., a roof) by a base 140. The housing 100 is connected to the base 140. The light emitting assembly 20 and the light transmitting member 30 are disposed in the housing 100. The housing 100 is transparent to light. The light emitted from the light-transmitting member 30 can be transmitted through the housing 100.

Therefore, in the present embodiment, the white LED beads 22 emit light in a straight-emitting form. The second light emitting surface 30b of the light transmitting member 30 is disposed opposite to the first light emitting surface 22a of the white LED lamp bead 22. The second light emitting surface 30b of the light transmitting member 30 is a curved surface, which is beneficial to converging or diffusing light.

In some examples, along the thickness direction of the light-transmitting member 30, the light-entering surface 30a of the light-transmitting member 30 is spaced from the first light-exiting surface 22a of the white LED lamp bead 22, so that a gap is formed between the light-entering surface 30a of the light-transmitting member 30 and the first light-exiting surface 22a of the white LED lamp bead 22. The light inlet surface 30a is a curved surface, which is beneficial to converging or diffusing light.
