Description
Technical Field
[0001] The utility model relates to the technical field of ceiling washing or wall washing, in particular to a fixing structure of a wire groove lamp lens for washing ceilings. Background Art
[0002] Trough lights are a type of lamp installed on the ceiling, usually used to provide lighting and decorative effects. They are usually designed to be embedded or hidden to coordinate with the ceiling and create a simple and modern visual effect. Trough lights can be connected to the power supply through wires or cables and can be controlled by switches or intelligent control systems. Trough lights are available in a variety of types and styles, including LED trough lights, fluorescent trough lights, etc. LED trough lights are usually more energy-efficient and environmentally friendly, with longer service life and better color performance. Fluorescent trough lights are usually cheaper and suitable for some places that do not require high light.
[0003] The existing ceiling trough light lens and its fixing structure adopt a milky white cover to irradiate light;
[0004] Although the traditional milky white cover or fluorescent method can wash the color evenly, it can not wash far enough and the uniformity is poor. Using a lens to wash the ceiling can wash far and have good uniformity, but it is easy to produce yellow spots. This patent is to solve the yellow spot problem of lens washing ceilings while retaining the advantage of good uniformity. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a fixing structure of the lens of the wire trough lamp for washing the ceiling, which can effectively reduce the yellow spot problem of the wire trough lamp without sacrificing the uniformity of illumination on the ceiling, and can effectively solve the problems in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing structure of a ceiling-washing wire trough lamp lens, comprising a profile;
[0007] Profile: An inclined plate is fixedly connected inside it, a light source substrate is arranged on the left end of the upper surface of the inclined plate, a light source is arranged at the center of the upper surface of the light source substrate, the output end of the light source is electrically connected to the output end of the external control switch, a flange is fixedly connected to the upper end of the profile, a lens is arranged between the flanges, a reflecting surface one is fixedly connected to the left end of the lower surface of the lens, a reflecting surface two is fixedly connected to the right end of the lower surface of the lens, the right end face of the reflecting surface one is fitted with the left end face of the reflecting surface two, a ceiling is arranged on the right side of the profile, which can effectively reduce the yellow spot problem of the cable trough lamp without sacrificing the uniformity of illumination on the ceiling.
[0008] Furthermore, the normal of the light source is rotated 30 to 50 degrees away from the ceiling relative to the vertical plane, so that more light can be distributed to the reflecting surface one, and the light on the reflecting surface two and the light incident surface two can be reduced, thereby weakening the yellow spot on the ceiling near the lamp position, and at the same time improving the utilization rate of the light on the ceiling.
[0009] Furthermore, both the first and second reflective surfaces are arc-shaped, and the arc length of the first reflective surface is 1.3 to 1.7 times the arc length of the second reflective surface, thereby enabling the first reflective surface to receive more light from the light source. Figure 2 As shown in the figure, because the light spot of reflective surface 1 is yellowish on the left and white on the right, and the ceiling is on the right side of reflective surface 1 and relatively far away from reflective surface 1, reflective surface 1 is responsible for illuminating the entire ceiling from near to far. On the contrary, the light spot of reflective surface 2 is yellowish on the right and white on the left, and is relatively close to the ceiling, so it is mainly responsible for illuminating the middle and far distance of the ceiling.
[0010] Furthermore, the right end of the reflecting surface one is fixedly connected to the light incident surface one, the right end of the light incident surface one is fixedly connected to the light incident surface two, the right end of the light incident surface two is fixedly connected to the light incident surface three, and the light incident surface four is fixedly connected between the light incident surface three and the reflecting surface two, forming the light incident surface of the light source.
[0011] Furthermore, the light incident surface 2 is curved, and the light incident surface 1, the light incident surface 3 and the light incident surface 4 are all straight lines. The light incident surface 1, the light incident surface 2, the light incident surface 3 and the light incident surface 4 form an inclined M shape, which can make the bottom of the lens closer to the light-emitting surface of the lamp bead, thereby reducing light loss.
[0012] Furthermore, the plane of the lens is a light emitting surface, providing a channel for the emission of light.
[0013] Compared with the prior art, the utility model has the following advantages:
[0014] The personnel install the lens, the reflective surface 1 and other mechanisms with the ceiling through the profile. After the installation is stable, the personnel realize the operation of the light source through the external control switch. The light emitted by the light source contacts the reflective surface 1 and the reflective surface 2 under the action of the inclined M-shaped light-entering surface composed of the light-entering surface 1, the light-entering surface 2, the light-entering surface 3 and the light-entering surface 4. At the same time, more light enters the reflective surface 1. Under the reflection of the reflective surface 1 and the reflective surface 2, the light is emitted through the lens to wash the ceiling. Due to the structural characteristics of the LED lamp beads (i.e., the area of the phosphor is large and the area of the blue light chip is small), the direct light spot of the lens is always white in the middle and yellow at the edge. It can be seen that the light spot of the reflective surface 1 is yellowish on the left and white on the right; on the contrary, the light spot of the reflective surface 2 is yellowish on the right and white on the left. Because the reflective surface 1 mainly irradiates the entire ceiling from near to far, and the reflective surface 2 only irradiates the middle and far parts of the ceiling, the lens solution of this patent can effectively weaken the yellow spot near the position of the ceiling near the lamp without sacrificing the uniformity of illumination on the ceiling. Although the macula theoretically exists in the distance, it is not obvious because the irradiation area is large and the macula is diluted. BRIEF DESCRIPTION OF THE DRAWINGS

The emitting surfaces 27 are all arc-shaped, the arc length of the reflecting surface 16 is 1.3 to 1.7 times the arc length of the reflecting surface 27, the reflecting surface 27 is close to the ceiling 5, the right end of the reflecting surface 16 is fixedly connected to the light incident surface 18, the right end of the light incident surface 18 is fixedly connected to the light incident surface 29, the right end of the light incident surface 29 is fixedly connected to the light incident surface 3 10, and the light incident surface 4 11 is fixedly connected between the light incident surface 3 10 and the reflecting surface 27, the light incident surface 29 is curved, the light incident surfaces 18, the light incident surfaces 3 10 and the light incident surfaces 4 11 are all straight lines, the light incident surfaces 18, the light incident surfaces 29, the light incident surfaces 3 10 and the light incident surfaces 4 11 form an inclined M shape, and the plane of the lens 3 is the light emitting surface.
[0021] The working principle of the fixing structure of the lens of a wire trough lamp for washing the ceiling provided by the utility model is as follows: when working, the personnel install the lens 3 and the reflecting surface 1 6 and other mechanisms in coordination with the ceiling 5 through the profile 1. After the installation is stable, the personnel realize the operation of the light source 4 through the external control switch. The light emitted by the light source 4 contacts the reflecting surface 1 6 and the reflecting surface 2 7 under the action of the inclined M-shaped light incident surface composed of the light incident surface 1 8, the light incident surface 2 9, the light incident surface 3 10 and the light incident surface 4 11. At the same time, more light enters the reflecting surface 1 6. Under the reflection of the reflecting surface 1 6 and the reflecting surface 2 7, the light is emitted through the lens 3 to wash the ceiling. Because the light spot of the reflecting surface 1 is yellowish on the left side and whiter on the right side, it mainly illuminates the entire ceiling from near to far, while the light spot of the reflecting surface 2 is yellowish on the right side and whiter on the left side, it mainly illuminates the middle and far distance of the ceiling. Therefore, the present implementation case can effectively weaken the yellow spot problem of the wire trough lamp without sacrificing the uniformity of illumination on the ceiling.
