Description

Polygonal mirror cavity structure and manufacturing method thereof

The invention relates to a polygonal mirror cavity structure and a manufacturing method thereof, in particular to a multi-piece single-sided mirror assembled and the single-sided mirror structure and the process can reduce the stress of the mirror and the frame bonding, and can reduce the stress. The influence of component tolerances on assembly.

The principle of light-emitting diode (LED) is to use an applied voltage to combine electrons and holes in the semiconductor, and to release energy in the form of light energy. The early LEDs only have two kinds of red and green light. It was not possible to produce white light. At that time, LED was mainly used in the production of indicator lights. Until 1994, Nichia developed a neon LED, which made it possible to produce white light by LED, plus low voltage and high luminous power. Advantages, LED has gradually become the new darling of the field of lighting.

At present, there are four main methods for producing white light by LED: direct mixing red orange blue (RGB) three-color LEDs, and illuminating yellow fluorescent powder with neon LEDs to generate yellow light after the fluorescent powder is excited. The blue light emitted by the LED is mixed with white light, and the multi-color fluorescent powder is excited by the fluorescent LED to make the long-wavelength color light generated by the fluorescent powder and the blue light emitted by the LED to be mixed with white light, and the ultraviolet light (UV) LED is used to excite the RGB fluorescent light. The RGB color light generated by the light powder and excited by the phosphor powder is mixed into white light.

Among them, the method of using the phosphor powder will face the service life limitation caused by the stability of the phosphor powder, and the RGB LED chip can be used to avoid this problem, and at the same time, the RGB three-color LED chip respectively generates RGB three. The color light can be adjusted to the color light intensity of each LED chip to achieve the function of adjusting the color temperature, and has high color rendering, so it can be used as an ideal white light source.

The RGB color light generated by the RGB three-color LED chip needs to pass through the light mixing cavity to make the color light uniform. The conventional mixed cavity structure mostly has a reflection function on the inner surface, a regular polygon or a circular shape, and the regular polygonal structure can be assembled through the complex number. Compared with the circular structure, the single-sided unit is less difficult to manufacture and suitable for mass production. Therefore, it is a common practice to use a polygonal mirror cavity as a mixed cavity of RGB mixed white LEDs.

The method for making a single-sided mirror unit included in a polygonal mirror cavity is to lay the frame flat, place the glue on the inner surface of the frame upward, and then place the mirror, or place the mirror flat on the mirror. Place the adhesive on the back of the upper side and place the frame. Then press to make the mirror adhere to the frame and flatten the mirror and the frame. However, the missing method is that the glue solidifies under pressure. Bonding the mirror and the frame is easy to generate stress inside, which causes the mirror to deform and affect the smoothness and optical uniformity of the mirror. In addition, when the mirror and the frame are pressed, there is a risk of the mirror being broken.

It is an object of the present invention to provide a polygonal mirror cavity structure including each of the single-sided mirrors for adjusting the thickness of the adhesive layer to counteract the influence of the thickness tolerance caused by the mirror fabrication, so that between two adjacent mirrors Keep the proper size gap to avoid light leakage or collision damage.

Another object of the present invention is to provide a polygonal mirror cavity structure, wherein the end of each single-sided mirror can accommodate the other end of the adjacent single-sided mirror, and the structure can buffer the length tolerance caused by the mirror fabrication. The length tolerance of the mirror is not affected by the assembly of the polygonal mirror cavity structure.

Another object of the present invention is to provide a method for manufacturing a polygonal mirror cavity structure, which supports a mirror and a frame through a jig and creates a gap therebetween, and the size of the gap is adjusted according to the thickness tolerance caused by the mirror, so that the assembly is performed. When the single-sided mirror is a polygonal mirror structure, the proper gap between the mirrors is maintained to avoid light leakage or collision damage.

Another object of the present invention is to provide a method for manufacturing a polygonal mirror cavity structure, in which a glue injected from a bead injection hole is formed and a natural flow of the adhesive is filled to fill a void, and then solidified to form an adhesive layer, thereby avoiding stress inside the adhesive layer. However, the strength of the polygonal mirror structure is weakened or the mirror surface unevenness is caused to cause a problem that the optical uniformity of the mirror cavity is lowered.

In order to achieve the above-mentioned various purposes and effects, the present invention discloses a polygonal mirror cavity structure which is assembled by a plurality of single-sided mirrors, each of which includes a frame, a mirror and an adhesive layer. The frame has an inner surface, one end of the frame is convexly disposed with a first abutting portion, and the other end is provided with a second abutting portion, and the first abutting portion includes a top surface and a side surface; a mirror is disposed on the inner surface of the frame, and a first end of the mirror abuts against the side of the first abutting portion; the adhesive layer is formed between the inner surface and the mirror; When the single-sided mirrors are assembled into the polygonal mirror cavity structure, the inner surface of the frame faces the inner side of the polygonal mirror cavity structure, and the top surface of the first abutting portion of each single-sided mirror is phase-phased The second abutting portion of the adjacent single mirror is combined, and a second end of each mirror forms a gap with the first end of the mirror of the adjacent single mirror.

When the gap is too large, the polygonal mirror cavity structure will have a lack of light leakage. When the gap is insufficient, the polygonal mirror cavity structure will not be assembled, or each single mirror will collide with each other and be damaged. Therefore, it is necessary to maintain the gap of appropriate size. Adjusting the thickness of the adhesive layer can adjust the overall thickness of the single-sided mirror, and affect the size of the gap, that is, the thickness tolerance of the mirror during fabrication can be offset by adjusting the thickness of the adhesive layer.

In addition, the first abutting portion of each single mirror and the first end of the mirror may further form an accommodating space for accommodating the second abutting portion of the adjacent single mirror or the mirror The second end, or the second abutting portion of each single mirror and the second end of the mirror may further form an accommodating space for accommodating the first affix of the adjacent single mirror a joint and the first end of the mirror. The accommodating space can buffer the length tolerance generated by the mirror during manufacture, so that the length tolerance does not affect the assembly of the polygonal mirror cavity structure, and the collision damage caused by insufficient spacing between the mirrors or the light leakage due to excessive spacing can be avoided. The problem.

The present invention further provides a method for fabricating a polygonal mirror cavity structure for fabricating the above-described polygonal mirror cavity structure, the method comprising: firstly placing the mirror back side up on a first bearing portion of the fixture Secondly, the frame is placed above the mirror, and the frame is supported by the fixture, so that the first end of the mirror abuts against the first abutting portion and the frame and the mirror have a gap, and then the adhesive is injected into the gap from the injection hole of the frame, and finally the first abutting portion of each single mirror and the second abutting portion of the adjacent single mirror are abutted against each other. And combining the single side mirrors into the polygonal mirror cavity structure.

The frame may be supported by a second carrying portion and a third carrying portion, or supported by a fourth carrying portion. Since the carrying portions are fixed, respectively supporting the frame and the mirror will make the single mirror The thickness remains fixed, and the size of the void varies with the thickness of the mirror, the size of which determines the thickness of the adhesive layer. The thickness tolerance of the mirror produced by the mirror will be offset by the thickness of the adhesive layer, so that each single mirror maintains a fixed overall thickness, so that the polygonal mirror cavity structure can be properly maintained after assembly. This gap of size avoids the occurrence of light leakage or collision damage between mirrors.

The thickness is such that a gap of appropriate size can be maintained between two adjacent mirrors to avoid light leakage or collision damage. In addition, the end of each single-sided mirror can form an accommodating space for accommodating the other end of the adjacent single-sided mirror. The space can buffer the length tolerance caused by the mirror, and the length tolerance does not affect the assembly of the polygonal mirror structure. Therefore, the polygonal mirror structure of the present invention can reduce the problem caused by the inaccurate size of the mirror. The adjustment of the thickness of the adhesive layer is achieved by the jig used in the manufacture of the single-sided mirror, and the frame and the mirror are respectively supported by the jig, and the gap between the gaps can be adjusted, and the thickness of the adhesive layer formed by the gap is changed, thereby achieving Buffer mirror thickness tolerance effect, while reducing the stress in the adhesive layer, to avoid weakening the overall strength.
