Technical Field

The present invention relates to a lamp, and more particularly to a device for projecting light according to a driving signal.

Background

In response to the market demand, the lamps are more and more diversified, and the application range is wider. When the lamp is driven to emit light, the light emitting component or the driving circuit in the lamp generates high temperature, and therefore, the lamp needs to have a good heat dissipation mechanism to ensure normal operation without affecting the service life of the light emitting component or the driving circuit.

SUMMERY OF THE UTILITY MODEL

The first surface of the heat dissipation unit is in contact with the light emitting unit. The heat dissipation shell is provided with a plurality of heat dissipation fins and is in contact with the second surface of the heat dissipation unit. The heat radiation fan is arranged in the lamp at a position corresponding to the heat radiation shell.

The present invention also relates to a lamp system comprising a plurality of lamps and a control host. The lamp comprises a light-emitting unit, a heat-radiating shell and a heat-radiating fan. The light emitting unit is used for receiving a driving signal. The first surface of the heat dissipation unit is in contact with the light emitting unit. The heat dissipation shell is provided with a plurality of heat dissipation fins. The heat dissipation shell is in contact with the second surface of the heat dissipation unit. The heat radiation fan is arranged in the lamp at a position corresponding to the heat radiation shell.

That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

When an element is referred to as being "connected" or "coupled," it can be referred to as being "electrically connected" or "electrically coupled. "connected" or "coupled" may also be used to indicate that two or more elements are in mutual engagement or interaction. In addition, although terms such as "first", "second", etc., are used herein to describe various components, such terms are only used to distinguish components or operations described in the same technical terms. Unless the context clearly dictates otherwise, the terms do not specifically refer or imply an order or sequence nor are they intended to limit the invention.

Fig. 1 to 4 are schematic views of a lamp 100 according to some embodiments of the present invention. Fig. 1 and 2 are schematic views of the lamp 100 from different viewing angles, and fig. 3 is an assembly schematic view of the lamp 100. Fig. 4 is a side view of a luminaire. In some embodiments, the luminaire 100 is implemented as a fish gathering lamp. The lamp 100 may be installed on the support frame 200 of the ship to project light to the water surface and attract shoal of fish, but the application of the present invention is not limited to the fish gathering lamp.

The lamp 100 includes a light emitting unit 110, a heat dissipating unit 130, a heat dissipating housing 140 and a heat dissipating fan 150. In some embodiments, the light emitting unit 110 includes a plurality of light emitting component groups (111-112 shown in FIG. 4, the details will be described in the following paragraphs). The light emitting component groups 111-112 can be light emitting diodes, but not limited thereto, and can also be other components for projecting light, such as incandescent lamps. In some embodiments, the lamp 100 further includes a circuit board C and a lens L, where the lens L may be a convex lens for refracting the light generated by the light emitting assembly group, so that the light can be projected outwards in a concentrated manner. In other embodiments, the lens L may be a planar lens or other type of mirror for directing the projection angle of light for different field and ship-type applications.

Please refer to fig. 1-4. The light emitting unit 110 is used for receiving the driving signal and is driven by the driving signal to project light. The driving signal may be a driving current or a driving voltage.

In some embodiments, the circuit board C is provided with a control chip of the light emitting unit and the light emitting module groups 111-112. The circuit Board C and the light emitting component groups 111-112 can be packaged as a single device or a single package of multiple light emitting diodes (e.g., a Chip On Board). In some other embodiments, the light emitting device groups 111-112 are disposed on the circuit board C in a surface mounted (surface mounted) manner. As shown in fig. 4, the first surface 130a (e.g., the surface corresponding to the circuit board C) of the heat dissipating unit 130 is in contact with the light emitting unit 110. The heat dissipating unit 130 is a fast heat conducting module, and in some embodiments, the heat dissipating unit 130 is configured as a sheet, and a first surface 130a thereof is used to abut against a side surface of the circuit board C where the light emitting component groups 111-112 are not disposed. In some other embodiments, the heat dissipating unit 130 includes a high thermal conductivity module. The high thermal conductivity module has a closed plate-shaped cavity and a working fluid therein for rapidly performing thermal conduction and thermal diffusion, so that the thermal energy generated by the circuit board C can be conducted to other parts on the heat dissipating unit 130 after contacting the first surface 130a of the heat dissipating unit 130.

The heat dissipation housing 140 contacts the second surface 130b of the heat dissipation unit 130, so that the heat generated by the light emitting unit 110 can be transferred to the heat dissipation housing 140 through the heat dissipation unit 130, and the heat is dissipated through the heat dissipation unit 130 and the heat dissipation housing 140. The heat dissipation housing 140 is provided with a plurality of heat dissipation fins 141. In some embodiments, as shown in fig. 4, the heat dissipation housing 140 is a forged (or extruded, cast) base, and the first side of the base has a groove for embedding the light emitting unit 110. As shown in fig. 4, in some embodiments, the heat dissipating housing 140 further includes a lens pressing frame 140 a. After the lens L is mounted on the heat dissipation housing 140, the lens pressing frame 140a is assembled on the heat dissipation housing 140 to fix the lens L. The lens L surrounds the light emitting unit 110, so that the light generated by the light emitting unit 110 is refracted by the lens L and projected outside the lamp 100. In addition, since the lens L is movably mounted on the heat dissipating case 140 by the lens pressing frame 140a, a user can replace a different type of lens.

In some embodiments, the heat dissipation housing 140 is a cylindrical body, and the heat dissipation fins 141 are disposed along the circumference of the heat dissipation housing 140 and extend radially outward. The heat dissipation fins 141 have a plurality of convection gaps therebetween to transfer heat energy on the heat dissipation housing 140 to the air through heat conduction and heat convection.

As shown in fig. 4, the heat dissipation fan 150 is disposed in the lamp 100 at a position corresponding to the heat dissipation housing 140. That is, when the heat dissipation fan 150 is driven, the generated air flow can be blown into the convection gaps between the heat dissipation fins 141, so as to improve the heat dissipation effect of the heat dissipation housing 140. In some embodiments, the heat dissipation fan 150 is fixed to a second side (e.g., a top) of the heat dissipation housing 140, and the light emitting unit 110 and the heat dissipation housing 140 are respectively located at two corresponding sides of the heat dissipation housing 140, but the invention is not limited thereto.

Accordingly, since the present invention integrates the "light emitting unit 110, the heat dissipating unit 130, the heat dissipating housing 140 and the heat dissipating fan 150" into the same device, the lamp 100 can have the simplest volume, and is convenient to set at any position, thereby greatly improving the flexibility of use and installation. In addition, the heat dissipation unit 130, the heat dissipation housing 140, and the heat dissipation fan 150 are different and mutually matched to ensure the heat dissipation effect of the lamp 100, so that the lamp 100 operates in an optimal working state.

In some embodiments, the luminaire 100 further includes a driving unit 160, a control unit 170, and a bracket 180. The driving unit 160 is electrically connected to the light emitting unit 110 and configured to receive a control signal. The control signal may be a command corresponding to brightness (e.g., brightness of 0-100%), and the driving unit 160 converts the control signal into a driving signal (e.g., voltage or current) so that the control unit 170 can drive the light emitting unit 110.

The control unit 170 (e.g., a control host) is electrically connected to the driving unit 160 and stores a plurality of adjustment signals. Each adjustment signal contains light color temperature data (e.g., 4000K, 5000K) or wavelength data (e.g., 570nm, 600nm) of different light sources. The control unit 170 may generate a control signal according to one of the adjustment signals according to different requirements (e.g., attracting different fishes), so as to adjust the brightness, color or wavelength of the light projected by the lamp 100.

The driving unit 160 and the control unit 170 may be a Central Processing Unit (CPU), a System on Chip (SoC), an application processor, a digital signal processor (digital signal processor), or a processing Chip or controller with a specific function. In some embodiments, the driving unit 160 is a driving circuit of the light emitting unit 110, and the control unit 170 is a host computer.

Referring to fig. 4 and 5, in some embodiments, the light emitting unit 110 further includes a first light emitting module group 111 and a second light emitting module group 112. Each of the light emitting

device groups

111, 112 includes at least one or more light emitting devices (e.g., light emitting diodes), and the light colors and the luminances generated by the different light emitting

device groups

111, 112 are different from each other. The control unit 170 generates a first light-emitting driving signal and a second light-emitting driving signal according to the adjustment signal of the application requirement. The first light emitting module group 111 is configured to receive the first light emitting driving signal transmitted from the driving unit 160, so that the generated light corresponds to the first light emitting brightness. The second light emitting component group 112 is used for receiving a second light emitting driving signal transmitted from the driving unit 160, so that the light generated by the second light emitting component group corresponds to a second light emitting brightness, and a specific light color and a specific brightness are generated.

For example, the first light emitting component group 111 is used for generating light of a warm color system (e.g., corresponding to a color temperature of 2700K or corresponding to a wavelength of 620nm), and the second light emitting component group 112 is used for generating light of a cold color system (e.g., corresponding to a color temperature of 6500K or corresponding to a wavelength of 470 nm). If the lamp 100 is set to project light with "color temperature 4000K", the control unit 170 may determine the light mixing ratio of the first light emitting component group 111 and the second light emitting component group 112 by looking up a table or calculating according to the corresponding adjustment signal of "4000K". For example: the first light emitting component group 111 needs to generate 60% of intensity (i.e., the aforementioned first light emitting brightness), and the second light emitting component group 112 needs to generate 40% of intensity (i.e., the aforementioned second light emitting brightness). After calculating the light mixing ratio, the control unit 170 generates the first light-emitting driving signal and the second light-emitting driving signal accordingly. Accordingly, the first light emitting component group 111 and the second light emitting component group 112 are driven under different light emitting luminances and mix light rays corresponding to color temperature or color (wavelength).

In other embodiments, the control unit 170 may also switch the light in a "mechanical control electronic circuit control" manner. Referring to fig. 5, the first light emitting module group 111 is used for projecting a first light source (e.g., red light), and the second light emitting module group 112 is used for projecting a second light source (e.g., blue light). When the control unit 170 receives the start instruction for the first time (e.g., the user presses the start button), the first light emitting component group 111 is enabled, but the second light emitting component group 112 is disabled, so that the light generated by the lamp 100 is "red light". When the control unit 170 receives the start instruction for the second time, the first light emitting component group 111 is disabled, but the second light emitting component group 112 is enabled, so that the light generated by the lamp 100 is "blue light". When the control unit 170 receives the start instruction for the third time, the first light emitting component group 111 and the second light emitting component group 112 are enabled at the same time, so that the light generated by the lamp 100 is "mixed light color of red light and blue light".

Referring to fig. 1-3, there are shown schematic assembly views of a lamp 100 according to some embodiments of the present invention. In some embodiments, the lamp 100 is locked on the supporting frame 200 in a hanging manner (as shown in fig. 1 and fig. 2), but in other embodiments, the lamp 100 may be installed in an upright manner, that is, the supporting frame 200 serves as a base, and the lamp 100 projects light towards any angle above or in front.

In some embodiments, the bracket 180 is a plate-shaped structure made of a metal material, and includes a mounting portion 181 and a pivoting portion 182. The first surface (e.g., the top) of the mounting portion 181 is locked to the supporting frame 200. The second surface (e.g., bottom) of the mounting portion 181 is used to lock the driving unit 160. As shown in fig. 3, in the present embodiment, the bracket 180 includes two pivoting portions 182, and first ends of the pivoting portions 182 are respectively connected to two ends of the mounting portion 181. The second ends of the pivoting portions 182 are respectively pivoted to two corresponding ends of the heat dissipation housing 140.

As shown in fig. 3, the mounting portion 181 and the pivoting portion 182 form a U-shaped structure, and surround the accommodating space 180 a. The driving unit 160 can be positioned in the accommodating space, so that the luminaire 100 can be designed to have a smaller volume. In addition, when the light emitting unit 110 projects light in a direction away from the mounting portion 181, the heat dissipating fan 150 and a portion of the heat dissipating housing 140 are positioned in the accommodating space 180 a.

In some embodiments, the bracket 180 further includes at least one locking portion 183 (in the structure shown in fig. 1 to 3, two locking portions 183 are included). The locking portion 183 is used to cooperate with the locking assembly 210 on the supporting frame 200, so that the lamp 100 is more firmly fixed on the supporting frame 200. As shown in fig. 1 and 3, the locking portion 183 is also plate-shaped, and has an axis Y perpendicular to the axis X of the mounting portion 181. That is, the middle portion of the locking portion 183 may be overlapped and attached to the mounting portion 181 and may be locked together by a screw. A portion of the locking portion 183 not overlapping the mounting portion 181 (i.e., a portion of the locking portion 183 adjacent to both ends) is provided with at least one locking hole 183 a. As shown in fig. 1 and 3, the positions of the locking holes 183a are located at two ends of the supporting frame 200, so as to correspond to the locking holes 210a of the locking assembly 210. In some embodiments, the locking assembly 210 is an omega-shaped plate that can be attached to three sides of the supporting frame 200. When the screw 220 passes through the locking hole 210a of the locking assembly 210 and the locking hole 183a of the locking part 183, and is locked, the bracket 180 and the supporting frame 200 are tightly fixed to each other.

Referring to fig. 3 and 6, in some embodiments, the heat dissipating housing 140 has a plurality of fixing holes 142 and pivot holes 143 for fixing the heat dissipating housing 140 to the bracket 180. The pivoting portion 182 has a groove 182a corresponding to the fixing holes 142. The groove 182a communicates with the fixing holes 142. The configuration of the groove 182a is arcuate. The heat dissipation housing 140 is pivotally connected to the bracket 180, and when the heat dissipation housing 140 is rotated to a specific angle, the heat dissipation housing can be fastened to the fixing hole 142 by a screw passing through the groove 182 a; meanwhile, the heat dissipation housing 140 is fixed at the specific angle on the bracket 180 by passing a screw through the pivot portion 182, then penetrating into the pivot hole 143, and screwing. Accordingly, the lamp 100 can be prevented from deviating from the angles of the heat dissipation housing 140 and the light emitting unit 110 due to external vibration.

In some embodiments, the heat dissipation fan 150 is electrically connected to the driving unit 160 for receiving the driving power transmitted from the control unit 170. In addition, the heat dissipation fan 150 is further configured to return a control parameter signal to the driving unit. The control parameter signal corresponds to a voltage value of the heat dissipation fan 150 for determining whether the driving motor is working normally. The driving unit 160 can determine whether the cooling fan 150 is operating correctly by detecting the control parameter signal provided by the cooling fan 150, and if the returned control parameter signal is at a low or abnormal level, it can determine that the cooling fan 150 is faulty. At this time, the driving unit 160 can disable the light emitting unit 110, so as to prevent the light emitting unit 110 from being damaged due to overheating.

In some other embodiments, a thermal sensor is further disposed in the driving unit 160 for detecting the temperature of the driving unit 160 (e.g., the temperature of the internal circuit or the ambient temperature). When the driving unit 160 determines that the temperature detected by the thermal sensing device is too high, the light emitting unit 110 may be disabled to avoid damage due to overheating.

Referring to fig. 7, in some embodiments, a plurality of lamps 100 may be collocated to form a lamp system 300. That is, the lighting system 300 includes a plurality of lighting apparatuses 100 and a control host 310. The structure of the lamp 100 is the same as that of the previous embodiment, and therefore, will not be repeated herein. In this embodiment, the driving unit 160 and the control unit 170 are integrated in the control host 310. A control unit 170 and a driving unit 160 are connected to the plurality of light emitting units 110 of the lamps 100, so that the control host 310 can control and monitor the operations of the plurality of light emitting units 110 at the same time. For example: the control host 310 is used for controlling the brightness, color or wavelength of the light generated by the lamps 100 and monitoring the status parameter signals of the lamps 100. The status parameter signal may be a control parameter signal (e.g., current of the cooling fan or the light emitting unit) as described in the embodiments of fig. 1 to 6, or may be a temperature value of the light emitting unit.

Accordingly, referring to fig. 4 and 6, since the driving unit 160 and the control unit 170 are not required to be installed in the heat dissipation housing 140 or on the support 180, but installed in the remote control host 310 to be connected to the plurality of light emitting units 110 at the same time, the volume of the lamp 100 is very compact, and the lamp can be installed at any position to project light at different angles. In other embodiments, the control unit 170 may generate different control signals to different lamps 100 according to the adjustment signals corresponding to different requirements (e.g., attracting different fishes), so that the intensity and the color of the light projected by each lamp 100 are different from each other, and the lamp system 300 may also enable the lamps 100 to generate the same brightness and color through the control unit 170.

Various components, method steps or technical features of the foregoing embodiments may be combined with each other without limiting the description sequence or the presentation sequence of the drawings in the present application.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the present invention.
