It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
First embodiment
Referring to fig. 2-9, the light source projector includes a fixed substrate 5, a movable substrate 6, a light emitting element 3 and an optical cover 4; the movable substrate 6 is movably connected with the fixed substrate 5; the luminous element 3 is fixedly arranged on the movable substrate 6 and is electrically connected with the movable substrate 6; the light-emitting angle of the light-emitting piece 3 is adjusted through the movable connection between the movable substrate 6 and the fixed substrate 5; the fixed substrate 5 comprises a bottom substrate 51 and a sidewall substrate 52, the sidewall substrate 52 surrounds the light emitting element 3 and is fixedly arranged on the bottom substrate 51; at least two mounting grooves for mounting the optical cover plate 4 are formed in the side wall substrate 52, the optical cover plate 4 is arranged in the mounting grooves and fixedly connected with the side wall substrate 52, and light emitted by the light emitting element 3 is emitted outwards after passing through the optical cover plate 4.
In this embodiment, the substrate is divided into two parts, a fixed substrate 5 and a movable substrate 6. The position of the fixed substrate 5 is relatively fixed, and the fixed substrate 5 and the movable substrate 6 are movably connected, that is, the relative position between the fixed substrate 5 and the movable substrate 6 can be changed by adjusting the movable connection between the two.
The light emitting element 3 is disposed on the upper surface of the movable substrate 6, and is fixedly and electrically connected to the movable substrate 6. The fixed connection means that the light emitting element 3 is connected with the movable substrate 6 and the relative position is fixed, and the electrical connection means that the light emitting element 3 can be electrified through the movable substrate 6. Similarly, the light emitting element 3 is fixedly connected and electrically connected with the movable substrate 6, if the light emitting element 3 is a normal chip, the light emitting element can be fixedly connected by gluing, and the light emitting element can be electrically connected by a lead; if the light emitting member 3 is a flip chip, the fixing connection and the electrical connection can be simultaneously realized by means of solder or conductive adhesive. In the embodiment of the present invention, the specific type of the light Emitting element 3 may be a VESEL (Vertical-Cavity Surface-Emitting Laser) Laser chip or an LED chip.
When the fixed substrate 5 and the movable substrate 6 are kept connected and the relative position changes, the light-emitting member 3 arranged on the upper surface of the movable substrate 6 can adjust the light-emitting position along with the position change between the fixed substrate 5 and the movable substrate 6, so that light-emitting at different angles is realized, and after being emitted through the optical cover plate 4, the light-emitting is different light-emitting patterns. Therefore, the adjustment of the light emitting effect of the light source projector can be realized, so that the light source projector does not need to be fixed in a light emitting pattern and can be applied to various scenes.
This embodiment provides an alternative connection structure between the fixed substrate 5 and the movable substrate 6, which is as follows:
the upper surface of the bottom substrate 51 is provided with a containing groove 53, the bottom surface of the containing groove 53 comprises a first arc surface 71 extending to the position of the bottom surface of the bottom substrate 51, the movable substrate 6 is arranged in the containing groove 53, the bottom surface of the movable substrate 6 is provided with a second arc surface 72 matched with the first arc surface 71, the first arc surface 71 and the second arc surface 72 are in mutual contact, and the sliding connection between the first arc surface 71 and the second arc surface 72 can be realized along the arc surface trend between the first arc surface 71 and the second arc surface 72; the bottom base plate 51 and the movable base plate 6 are movably connected through the contact between the first arc surface 71 and the second arc surface 72.
The fixing substrate 5 includes a bottom substrate 51 and a sidewall substrate 52, wherein the bottom substrate 51 is disposed at the bottom, and the sidewall substrate 52 surrounds the light emitting element 3 and is fixed to the bottom substrate 51. The bottom substrate 51 is provided with a receiving groove 53 on the upper surface thereof, the bottom surface of the receiving groove 53 is an arc-shaped first arc surface 71, and the bending direction of the arc surface faces the bottom surface of the bottom substrate 51, so that the receiving groove 53 in the bottom substrate 51 is a downward convex structure, please refer to fig. 3. The movable substrate 6 is placed in the accommodating groove 53, the bottom surface of the movable substrate 6 is also an arc-shaped second arc surface 72, and the second arc surface 72 and the first arc surface 71 are in contact and matched with each other, please refer to fig. 4. The matching means that the radian of the first arc surface 71 and the second arc surface 72 is consistent within the allowable error range, and the difference can be slight as long as the sliding between the first arc surface 71 and the second arc surface 72 in the arc surface direction is not limited; the arc lengths of the first arc surface 71 and the second arc surface 72 are not limited, and the first arc surface 71 may be longer, or the second arc surface 72 may be longer. Due to the relationship between the first arc surface 71 and the second arc surface 72, the movable connection between the movable substrate 6 and the bottom substrate 51 can be realized, the movable connection realizes the movement by the relative sliding between the two arc surfaces, and the connection is realized at least by the up-and-down contact relationship between the movable substrate 6 and the bottom substrate 51. In other words, the connection relationship between the movable substrate 6 and the base substrate 51 may be only a pure contact relationship in which the movable substrate 6 is placed on the base substrate 51, and the embodiment is not limited thereto.
When the first arc surface 71 and the second arc surface 72 slide relatively, the movable substrate 6 rotates around the arc surface, so that the light emitting direction of the light emitting element 3 on the upper surface thereof can be adjusted, please refer to fig. 5.
In some embodiments, in order to enhance the connection strength and stability between the bottom substrate 51 and the movable substrate 6, a sliding rail 61 corresponding to the first arc surface 71 is disposed on at least one inner sidewall of the accommodating groove 53, a sliding shaft 62 corresponding to the size of the sliding rail 61 is fixedly disposed on a side surface of the movable substrate 6, the sliding shaft 62 is disposed in the sliding rail 61, and the sliding shaft 62 is slidable along the rail extending direction of the sliding rail 61. The sliding rail 61 corresponds to the first arc surface 71, which means that the sliding rail 61 is an arc-shaped rail, and the sliding relationship between the sliding shaft 62 and the sliding rail 61 is consistent with the sliding relationship between the first arc surface 71 and the second arc surface 72; the provision of the slide rail 61 and the slide shaft 62 can improve the stability of the connection between the base substrate 51 and the movable substrate 6, so that relative movement between the base substrate 51 and the movable substrate 6 other than sliding in the direction of the arc surface does not occur, as shown in fig. 6.
In some embodiments, the sliding rails 61 are symmetrically disposed on two opposite inner sidewalls of the accommodating groove 53, and the sliding shafts 62 are correspondingly disposed on two opposite sides of the movable substrate 6. The two sliding rails 61 may be disposed on the inner side walls of the accommodating groove 53; correspondingly, the sliding shafts 62 also include at least two sliding shafts, which are correspondingly disposed on the opposite outer side surfaces of the movable base plate 6.
In some embodiments, the sliding rail 61 penetrates the inner sidewall of the receiving groove 53 and the outer sidewall of the bottom substrate 51, and exposes the sliding shaft 62. Since the connection relationship between the movable substrate 6 and the fixed substrate 5 cannot be easily adjusted from the outside after the light source projector is packaged, the sliding rail 61 in this embodiment is not only disposed on the inner sidewall of the accommodating groove 53, but is disposed to penetrate from the inner sidewall of the accommodating groove 53 to the outer sidewall of the bottom substrate 51, that is, the entire sidewall of the bottom substrate 51, and is penetrated by the sliding rail 61; correspondingly, the sliding shaft 62 is arranged in the sliding rail 61, and the sliding rail 61 penetrates through the whole side wall of the bottom substrate 51, so that the sliding shaft can be exposed, and under the condition that the sliding shaft 62 is exposed, the sliding shaft 62 can be directly touched, so that the relative position between the sliding shaft 62 and the sliding rail 61 can be adjusted, and accordingly, the relative position between the movable substrate 6 and the bottom substrate 51 can be adjusted, and the light emitting pattern can be adjusted. To facilitate tampering with the sliding shaft 62, the sliding shaft 62 may also protrude outwardly beyond the outer side wall of the base plate 51.
In some embodiments, a first locking member is further disposed between the bottom substrate 51 and the movable substrate 6, and the first locking member is configured to lock a relative position between the bottom substrate 51 and the movable substrate 6 in a preset state when the first arc surface 71 and the second arc surface 72 are in the preset state. The bottom substrate 51 and the movable substrate 6 can be movably connected to realize the adjustment of the relative position; when the relative position between the two is adjusted to a designated position, that is, the first arc surface 71 and the second arc surface 72 are in a preset state, the current state can be temporarily fixed, so that the relative position between the bottom substrate 51 and the movable substrate 6 is fixed therewith, and the light emitting pattern of the light emitting member 3 is maintained. The first locking member may be a separate component or may be formed by combining a plurality of components.
In some embodiments, the first locking member includes friction surfaces disposed on the first arc surface 71 and the second arc surface 72, respectively. This means that the first arc surface 71 and the second arc surface 72 are rough surfaces having a certain friction factor, which can achieve relative sliding between the first arc surface 71 and the second arc surface 72 in the direction of the arc surfaces, and can fix their relative positions depending on their surface roughness when sliding to a specified position. Since there is no absolutely smooth surface, any surface may be referred to as a rough surface, and the rough surface in this embodiment refers to a surface whose friction factor satisfies a certain requirement, so that the first arc surface 71 and the second arc surface 72 can be kept relatively still at a required relative position without applying other external force. When the first locking member is implemented by friction surfaces of two arc surfaces, the designated position thereof may be an arbitrary position, in other words, the position adjustment between the first arc surface 71 and the second arc surface 72 is a stepless adjustment.
In some embodiments, when the sliding rail 61 corresponding to the first arc surface 71 is disposed on at least one inner sidewall of the receiving groove 53, the sliding shaft 62 corresponding to the size of the sliding rail 61 is fixedly disposed on a side surface of the movable substrate 6, the sliding shaft 62 is disposed in the sliding rail 61, and the sliding shaft 62 can slide along the rail extending direction of the sliding rail 61, the first locking member includes a plurality of first bayonets 81 disposed on the sidewall of the sliding rail 61, and a first limiting member 82 engaged with the first bayonets 81; each of the first bayonets 81 includes a first notch and a second notch which are disposed on two sidewalls of the sliding rail 61 in a pair, and the first position-limiting member 82 is disposed between the first notch and the second notch to limit the movement of the sliding shaft 62, please refer to fig. 7. If the sliding rail 61 and the sliding shaft 62 in the above-described embodiment are disposed between the bottom base plate 51 and the movable base plate 6, a plurality of first bayonets 81 may be further disposed on the sliding rail 61, and position locking is achieved by cooperation between the first bayonets 81 and the first stoppers 82. The first bayonet 81 includes a first notch and a second notch provided on two opposite side walls of the sliding rail 61, and if the first limiting member 82 is placed between the first notch and the second notch, the first limiting member 82 constitutes a locking mechanism that can limit a moving space of the sliding shaft 62 in the sliding rail 61, thereby achieving position locking thereof. The first bayonet 81 may be provided in plural so that the relative position between the movable substrate 6 and the base substrate 51 may be fixed at plural positions. For this arrangement, the adjustment of the positional relationship between the movable base plate 6 and the base plate 51 is a gear adjustment.
In some embodiments, a first positive electrode circuit layer 91 and a first negative electrode circuit layer 92 which are insulated from each other are disposed on the first arc surface 71, and the first positive electrode circuit layer 91 and the second negative electrode circuit layer 102 are used for being electrically connected with an external power supply; a second anode circuit layer 101 and a second cathode circuit layer 102 which are insulated from each other are arranged on the second arc surface 72, and the second anode circuit layer 101 and the second cathode circuit layer 102 are respectively electrically connected with the anode and the cathode of the luminescent part 3; the first positive electrode circuit layer 91 is electrically connected to the second positive electrode circuit layer 101, and the first negative electrode circuit layer 92 is electrically connected to the second negative electrode circuit layer 102, please refer to fig. 8 and 9. Since the movable substrate 6 is movably connected to the bottom substrate 51, and the movable substrate 6 is generally not directly electrically connected to the external power source, the one-arm substrate can be electrically connected to the external power source through the electrical connection between the movable substrate 6 and the bottom substrate 51. This can be achieved by providing a wiring layer on the surfaces of the first and second arc surfaces 71 and 72 that contact each other between the base substrate 51 and the movable substrate 6. A first positive electrode circuit layer 91 and a first negative electrode circuit layer 92 which are insulated from each other are arranged on the surface of the first arc surface 71, and a second positive electrode circuit layer 101 and a second negative electrode circuit layer 102 are correspondingly arranged on the surface of the second arc surface 72, wherein the positions of the first positive electrode circuit layer 91 and the second positive electrode circuit layer 101 correspond to each other, the positions of the first negative electrode circuit layer 92 and the second negative electrode circuit layer 102 correspond to each other, under the condition that the first arc surface 71 and the second arc surface 72 are contacted, the first positive electrode circuit layer 91 and the second positive electrode circuit layer 101 are contacted, and the first negative electrode circuit layer 92 and the second negative electrode circuit layer 102 are contacted; the second positive electrode circuit layer 101 and the second negative electrode circuit layer 102 are electrically connected to the positive electrode and the negative electrode of the light emitting element 3 on the movable substrate 6, respectively, and the light emitting element 3 and the bottom substrate 51 can be further electrically connected by the contact between the circuit layers. Because the bottom substrate 51 is relatively fixedly arranged, pins can be conveniently arranged on the bottom substrate 51 to be in contact with an external power supply to realize power supply.
The embodiment provides a light source projector, which comprises a fixed substrate 5, a movable substrate 6, a luminous element 3 and an optical cover plate 4; the movable substrate 6 is movably connected with the fixed substrate 5; the luminous element 3 is fixedly arranged on the movable substrate 6 and is electrically connected with the movable substrate 6; the light-emitting angle of the light-emitting piece 3 is adjusted through the movable connection between the movable substrate 6 and the fixed substrate 5; the fixed substrate 5 comprises a bottom substrate 51 and a sidewall substrate 52, the sidewall substrate 52 surrounds the light emitting element 3 and is fixedly arranged on the bottom substrate 51; at least two mounting grooves for mounting the optical cover plate 4 are formed in the side wall substrate 52, the optical cover plate 4 is arranged in the mounting grooves and fixedly connected with the side wall substrate 52, and light emitted by the light emitting element 3 is emitted outwards after passing through the optical cover plate 4. Thereby this embodiment sets up illuminating part 3 on activity base plate 6 through fixed base plate 5 and the activity base plate 6 that set up swing joint, can realize the regulation of light-emitting through the swing joint between fixed base plate 5 and the activity base plate 6, has promoted user experience.
