Detailed Description
Example 1:
as shown in fig. 1-3, a laser light emitting device includes a laser diode, the laser diode includes a package 101, a light exit glass 102 is disposed at one end of the package 101, and the light exit glass 102 is recessed into the package 101 to form a groove. The light outlet glass 102 belongs to a vulnerable part and is easy to damage due to collision in the transportation or use process. The design reduces the contact chance between the light outlet glass 102 and the outside, and reduces the probability of breakage of the light outlet glass 102. In order to shorten the length of the optical path, the transmission-type fluorescent sheet 103 is adopted, and the fluorescent sheet 103 includes a transparent heat-conducting substrate 103a and a fluorescent material 103b on the surface of the substrate 103 a. The transmissive phosphor sheet 103 has a shorter optical path than the reflective phosphor sheet 103, and is more suitable for use in this design. The laser light emitted through the light exit glass 102 includes a fast axis and a slow axis, and the light emission angle of the laser light in the fast axis direction is larger than the light emission angle of the laser light in the slow axis direction. The size of the light spot formed by the laser light emitted through the light exit glass 102 in the near field is different from that in the far field, and the light spot formed by the laser light in the near field is smaller than that in the far field. Therefore, in order to reduce the size of the light emitting point of the laser on the fluorescent sheet 103, in the present embodiment, the surface of the substrate 103a away from the fluorescent material 103b is embedded in the recess formed by the light exit glass 102 recessed into the package 101. The above technical means describes that the surface of the substrate 103a far from the fluorescent material 103b is embedded in the light outlet glass 102, and the fluorescent sheet is entirely or partially in the groove, which satisfies the requirements of the above technical means. The technical scheme reduces the distance between the substrate 103a and the light outlet glass 102, and reduces the spot size of the laser on the fluorescent sheet 103 by reducing the distance of the laser light path.
As can be seen from the above analysis, the smaller the distance between the surface of the substrate 103a away from the fluorescent material 103b and the light exit glass 102, the better, but there is a gap between the surface of the substrate 103a fitted into the groove and the light exit glass 102 at the time of assembly. The reason for providing the gap is that a large amount of heat is generated during the use of the laser diode, and the fluorescent sheet 103 is easily damaged when the fluorescent sheet 103 is in close contact with the light exit glass. Not only shortens the service life of the fluorescent sheet, but also influences the lighting effect of the device. It is necessary to provide a gap between the substrate 103a and the light exit glass 102.
According to the above-described technical means, the smaller the distance between the light exit glass 102 and the substrate 103a, the smaller the light spot formed on the phosphor sheet, which is a desired result in practical use, but the two may not be close to each other. When the position of the phosphor sheet 103 is changed, the spot of the laser beam on the phosphor sheet 103 becomes large or the phosphor sheet 103 is burned out at high temperature, and thus the control of the distance between the two becomes difficult. In order to solve the problem, the laser light emitting device further includes a fixing plate 104, and the fluorescent sheet 103 is fixed on the fixing plate 104. The fixing plate 104 fixes the fluorescent sheet 103, so that the spot of the laser on the fluorescent sheet 103 is prevented from being enlarged or stuck together due to the change of the relative position of the fluorescent sheet 103 and the light outlet glass 102 in the use process, and the fluorescent sheet 103 is prevented from being damaged due to high temperature.
According to the technical scheme, the fixing plate 104 is used for fixing the fluorescent sheet 103, and the fluorescent sheet 103 is the transmission-type fluorescent sheet 103, so that the fixing of the fixing plate 104 on the fluorescent sheet 103 can easily shield the laser passing through the fluorescent sheet 103 and the fluorescent light emitted by the laser-excited fluorescent material 103 b. In view of the above problem, the present embodiment is a preferred embodiment in which one light-transmitting hole 105 is formed in the fixing plate 104, and the light-transmitting hole 105 is covered with the fluorescent sheet 103. The technical scheme avoids the emergence of laser and fluorescence by the fixing plate 104 for fixing the fluorescence piece 103 and avoids the reduction of the light intensity of the light-emitting device.
The fixing plate 104 is used to fix the fluorescent sheet 103, and since one surface of the fluorescent sheet 103 is coated with the fluorescent material 103b, what connection method is used for the fixing plate 104 and the fluorescent sheet 103, and the connection position needs to be given. In the present embodiment, the side surface of the fluorescent sheet 103 is bonded to the fixing plate 104, and in a preferred embodiment, the side surface of the fluorescent sheet 103 is bonded to the inner wall of the light transmitting hole 105. The fixing method does not damage the fluorescent material 103b, and the light-passing hole 105 also plays a role in protecting the fluorescent material 103 b.
Since the laser light emitted through the light exit glass 102 includes a fast axis and a slow axis, the light emission angle of the laser light in the fast axis direction is larger than the light emission angle of the laser light in the slow axis direction. The facula that forms when laser reachs logical unthreaded hole 105 is rectangular shape, and for make full use of laser, logical unthreaded hole 105 designs for rectangular shape in this application, and the length direction of logical unthreaded hole 105 sets up along the length direction of the laser facula of light-emitting mouthful glass 102 outgoing. The light spot formed by the laser emitted through the light outlet glass 102 and the light through hole 105 are both in a strip shape, the length direction of the light through hole 105 is the same as that of the laser light spot, and the design avoids that part of the laser cannot be emitted through the light through hole 105, so that the utilization rate of the laser is improved. In a preferred embodiment, the center of the laser spot emitted from the light exit glass 102 coincides with the center of the light transmission hole 105. The design avoids the boundary of the laser facula being blocked by the light through hole 105, and the effect of emergent light of the laser light-emitting device is influenced.
The laser-excited fluorescent material 103b emits a fluorescent light spot with a blurred boundary. Secondly, the spot shape cannot be changed according to the user's needs. In this embodiment, a preferable embodiment is provided, in which a diaphragm 106 is added at the rear end of the optical path of the fluorescent sheet 103, one side of the diaphragm 106 is the fluorescent material 103b, the other side of the diaphragm covers the light-passing hole 105, and at least one diaphragm hole 107 is arranged in the area where the diaphragm 106 covers the light-passing hole 105. The boundary of the fluorescent light spot is shielded by adding the diaphragm 106, so that the white light emitted by the laser light-emitting device is more uniform. Next, the diaphragm plate 106 is provided with a required diaphragm aperture 107, and the shape of the diaphragm aperture 107 is designed as required. In this embodiment, an example of one diaphragm hole 107 is given, but the diaphragm hole 107 may be provided in plural as necessary.
The laser light emitted through the light port glass 102 forms a small spot area on the fluorescent sheet 103, and the energy density of the laser light is high at this time, which is already significantly beyond the capability of the fluorescent material 103b in unit area to convert the laser light. In order to fully utilize the laser and avoid the waste of the laser, a preferred embodiment of the present invention is that the surface of the substrate 103a embedded in the groove is a rough surface. The surface of the substrate 103a embedded in the groove is rough, and the rough surface diffuses the laser light passing through the substrate 103a to enlarge the area of the spot formed on the fluorescent sheet 103. Secondly, the long-strip-shaped laser spot formed on the fluorescent sheet 103 can be shaped, the length of the laser spot is reduced, and the width of the laser spot is increased.
In order to further improve the color rendering capability of the laser light emitting device, it is necessary to control the color temperature of the laser light emitting device, which is realized by controlling the ratio of the laser light to the fluorescence of the laser light emitting device. This embodiment presents a method of controlling the color temperature, the surface of the fluorescent material 103b is covered with a diffuse scattering sheet comprising a transparent second substrate and white particles between the second substrate and the fluorescent material. A diffuse scattering sheet is added, and white particles in the diffuse scattering sheet reflect the laser light back to the fluorescent material 103b to re-excite the fluorescent material 103 b. Therefore, the proportion of the laser light to the fluorescence in the emergent light can be controlled by increasing or decreasing the amount of the white particles according to needs.
The purpose of adding the diffuse scattering sheet is to control the color temperature of the laser light emitting device, if the fluorescent material 103b and the diffuse scattering sheet are completely and tightly attached to each other, which is equivalent to that the diffuse scattering sheet and the fluorescent material 103b form a whole, laser light and fluorescence emitted by the fluorescent material 103b enter the diffuse scattering sheet and then emit into the air, which is equivalent to that the diffuse scattering sheet is composed of a material with a large refractive index and a material with a small refractive index, most of the laser light and the fluorescence are totally reflected in the diffuse scattering sheet, and only a small part of the laser light and the fluorescence can emit into the air. Therefore, in this embodiment, a technical scheme is provided in which an air gap is provided between the fluorescent material and the diffuse scattering sheet, and this technical scheme prevents the laser and the fluorescence from being emitted from the diffuse scattering sheet after being reflected or refracted many times. In a preferred embodiment, the thickness of the air gap is equal to or less than the thickness of the fluorescent material 103 b. The air gap is usually formed by placing the diffuse scattering sheet directly on the surface of the fluorescent material 103b, and the diffuse scattering sheet and the fluorescent material may not be completely attached to each other. However, an excessively thick air gap may result in an enlarged spot of light emitted from the diffuser, which is not suitable for application in the field of illumination.
Example 2:
in example 1, the fluorescent sheet 103 was fixed by bonding the side surface of the fluorescent sheet 103 to the inner wall of the light transmitting hole 105 in such a manner that the fluorescent material 103b was not damaged and the light transmitting hole 105 also protected the fluorescent material 103 b. However, when the fluorescent sheet 103 is placed in the light transmitting hole 105, the difficulty of adhesion increases, and the adhesion is liable to be weak. As shown in fig. 6, in the present embodiment, the side of the fluorescent sheet 103 covered with the fluorescent material 103b is bonded to the fixing plate 104, and at this time, the part of the fluorescent sheet material 103b near the side of the fluorescent sheet is bonded to the fixing plate 104, thereby avoiding the influence on the generated fluorescence. This mode is connected with fixed plate 104 through the one side that fluorescence piece 103 covers fluorescence material 103b and the side of fluorescence piece 103, has guaranteed the fastness of connection, and secondly, avoids destroying the fluorescence material 103b that is used for producing fluorescence.
The diaphragm 206 is arranged between the fluorescent material 103b and the fixing plate 104, and the fluorescent material 103b is bonded to the fixing plate 104 while sandwiching the diaphragm 206 therebetween, without additionally fixing the diaphragm 206.
Although several embodiments of the present invention have been described in detail, the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
