The present invention relates to a hermetic lamp frame for removing blue light, and more particularly, a technique of arranging a blue light blocking film on the side of the light guide plate and sealing the foreign material so as not to be inserted.

In general, blue light refers to blue light of 380 nm to 500 nm in visible light, and has a short wavelength and high energy. Such blue light is emitted through the LCD screen of electronic devices such as smart phones, tablets, and computer monitors, which are rapidly spreading in recent years, and are also emitted through lighting devices such as led lights.

Blue light is stronger than other lights, so it retracts the eyes and exaggerates the muscles of the eyes, adding to the fatigue of the eyes, which causes tension to bind the shoulders and neck. In addition, strong wavelengths and energy can reach the inside of the eye, which may have a negative effect, and may directly damage the retina.

These blue lights also affect sleep health, and our body tells us when to sleep between day and night by the amount of light that reaches the retina. However, under the influence of various digital devices and LED lighting, the exposure to blue light continues to suppress the hormone (melatonin) secretion that induces sleep.

1 to 3, the sealed light frame 100 for removing blue light according to an embodiment of the present invention includes a horizontal portion 110 and a vertical portion 120. Here, the horizontal portion 110 and the vertical portion 120 is extruded to form a single body, but for convenience of description will be described by dividing the configuration.

The horizontal part 110 is formed with a support part 111 for fixing one side of the light guide plate 10. The support 111 is formed at one end of the horizontal portion 110 spaced apart in an 'c' shape. The light guide plate 10 is inserted into the spaced space. Both ends of the support 111 may be formed to be inclined inward to fix the side surface of the light guide plate 10. The light guide plate 10 is formed of a light transmitting material. The light guide plate 10 is a flat member having a constant thickness, and may be made of transparent acrylic, polymethylmethacrylate (PMMA), plastic, glass, or the like. In this case, the light guide plate 10 may be formed of a material having a predetermined refractive index so as to have a uniform luminance distribution so that the light of the LED 20 to be described later is distributed as a whole.

In addition, a reflective groove (not shown) at a predetermined angle may be formed on the upper surface of the light guide plate 10. The reflecting groove reflects light emitted from the side surface of the light guide plate 10 at a predetermined angle roll. In this case, the reflection groove may act as a prism to disperse light.

The pores between the plurality of acryl beads are filled with a blocking agent that blocks wavelengths of 240 to 400 nm or less. In this case, the wavelength of light to be blocked may be set differently according to the components of the blocking agent. For example, it is also possible to block blue light using a blocking agent having a component for blocking a wavelength of 420 to 450 nm or less. In this case, the blocking agent may include an adhesive component to fix the plurality of acrylic beads. It is also possible to use the adhesive of well-known transparent material as an adhesive component. Accordingly, it is possible to reduce the macular degeneration of the user's retina by blocking the light of the purple series.

A plurality of sliding grooves are formed inside the support part 111 of the horizontal part 110. In detail, the first sliding groove 112 is formed such that the LED 20 faces the side of the light guide plate 10 inserted into the support 111. In this case, the direction of orientation of the LED 20 faces the side of the light guide plate 10. The second sliding groove 113 is formed to insert the blue light blocking film 30 between the light guide plate 10 and the LED 20 inserted into the support 111. In this case, the blue light blocking film 30 is arranged to face the side of the light guide plate 10. Accordingly, the blue light is filtered by the blue light blocking film 30 while irradiating the LED 20 to the side of the light guide plate 10. In this case, cost can be reduced by minimizing the area of the blue light blocking film 30.

The blue light blocking film 30 is formed between the side of the light guide plate 10 and the LED 20 to block the blue light by absorbing a wavelength of 420 ~ 450nm or less during illumination. Specifically, the blue light blocking film 30 may be formed to a thickness of 140 to 160㎛ on one surface of the PET formed to a thickness of 40 to 60㎛.

Meanwhile, the wire groove 114 or the connection groove 115 may be further formed in the horizontal portion 110. The wire groove 114 is a groove in which the wire 50 for supplying power to the LED 20 is accommodated. This serves to align the wire 50 so that it is not tangled. The wire groove 114 may be formed to be parallel to the first sliding groove 112 or the second sliding groove 113. Wire groove 114 has a cross-sectional area is formed to a size that the wire 50 can be accommodated, the upper portion can be opened to facilitate the removal of the wire (50). The connection groove 115 serves to support the protruding member of the connection part 200 connecting the plurality of lamp frames 100 to be inserted and fixed. In addition, the nut is inserted into the connection groove 115 serves to secure the lamp frame 100 to the ceiling through coupling with an external bolt.

The vertical portion 120 is bent in the vertical direction to the other side of the horizontal portion 110 is formed. The vertical portion 120 is formed such that the hook portion 121 is formed in the shape of an arrowhead to be hooked to the bracket 40. In this case, the bracket 40 may be formed in various forms that are fixed to the ceiling and deformable so that the catching portion 121 is caught. The locking portion 121 of the vertical portion 120 is formed to be inclined to the surface in contact with the bracket 40 is to be fixed to the bracket 40 by the stepped surface of the locking portion 121 when moving over a certain depth.

The body portion 210 is connected to the lamp frame 100 on one side, the lamp frame 100 is connected to the other side in the vertical direction. The through-cutting surface 211 is formed at a position in contact with the wire groove 114 of each lamp frame 100 of the body portion 210. The through cut surface 211 is separated by an external force to allow the wire 50 to penetrate inward. The through incision surface 211 is separated from the body portion 210 when applying pressure with an awl or a ball pen to expose the through hole. The through-cutting surface 221 is formed with a wire passage 212 through which the wire can move in the body portion 210. The body portion 210 accommodates the wire 50 inserted through the through hole therein. Body portion 210 may be connected to the wire 50 by receiving a sensor or a speaker therein.

The connection protrusion 220 is formed to protrude on one side of the body portion 210 and is inserted into the connection groove 115. Connection protrusion 220 is formed to protrude at least one or more on the outer surface of the body portion (210). In this case, the protruding length of the connecting protrusion 220 may be changed by user setting. The cross-sectional shape of the connection protrusion 220 is preferably formed in a shape corresponding to the connection groove 115. Connection protrusions 220 are preferably formed on two of the four sides of the body portion 210, respectively. In this case, the two connecting protrusions 220 are formed in a perpendicular direction to each other.

The closing part 230 is integrally formed with the body part 210 and may be formed in two or more on the outer surface of the body part 210. The closing part 230 closes one end of the wire groove 114. This is to prevent the worms from moving to the wire groove 114 to move to the inside of the body portion (210). By preventing the wires 50 accommodated in the wire grooves 114 from being separated by the closing part 230, and preventing the insects from flowing in at the same time, the life of the LEDs can be extended.

Meanwhile, the hermetically sealed lamp frame 100 for removing blue light according to an embodiment of the present invention may further include a detector 300 and a controller 400.

The detection unit 300 may be formed inside the connection unit to detect whether or not the surrounding fire. For example, the detector 300 may be implemented as a smoke detection sensor to detect smoke. In addition, the sensing unit 300 may detect whether or not a fire by sensing the ambient temperature. This is to detect the fire by the lamp frame without installing a fire detector separately. In this case, the detection unit 300 may be implemented as a gas detection sensor to detect that the concentration of carbon monoxide or carbon dioxide in the air is variable.

In addition, the detector 300 may detect the illumination of the surroundings to detect whether the user approaches. This is to reduce power consumption by cutting off the power of LED when there is no user for a certain time. It is also possible to adjust the intensity of the lighting according to the daytime and nighttime of the ambient light. For example, when the ambient illumination is high, the intensity of illumination may be increased, and when the ambient illumination is low, the intensity of illumination may be reduced.

In addition, the sensing unit 300 may sense the proximity of the user by sensing the surrounding sound. The detector 300 may detect the presence or absence of an intruder by sensing a frequency of a surrounding sound. The sensing unit 300 may detect whether the user has many or few users by detecting the daybell of the surrounding sound. This is to variably adjust the LED light intensity depending on whether there are many users.

The controller 400 is a circuit element installed inside the connection portion. The controller 400 may control switching the output of the LED. The controller 400 may be connected to the detector 300 to obtain sensing information such as ambient temperature, gas, illuminance, and sound provided from the detector 300. For example, the controller 400 may determine the fire when the ambient temperature or the gas exceeds a preset value, or cut off the power of the LED to prevent the fire. In addition, the controller 400 may variably control the illumination intensity of the LED according to the ambient illumination or sound. In this case, it is also possible to additionally control the color or pattern of the LED.

In addition, the controller 400 may communicate with an external user terminal. In this case, the controller 400 may be Wi-Fi, Zigbee, Beacon, LoRA, 3G, 4G, LTE communication. The controller 400 may receive a control signal from an external user terminal and adjust the output of the LED. The controller 400 may authenticate the control signal of the user terminal according to whether the user terminal is in proximity. For example, when the user terminal inputs a preset gesture pattern in proximity to the user terminal, the controller 400 may recognize the user terminal as a user terminal and authenticate the control signal. In addition, the controller 400 may allow the user terminal to be controlled by authentication through a secret code even in a remote location.

The present invention has been described above with reference to the preferred embodiments described with reference to the drawings, but is not limited thereto. Therefore, the present invention should be construed by the description of the claims intended to cover obvious modifications derivable from the described embodiments.
