Description

TECHNICAL FIELD

The present application relates to the field of lighting technology, specifically relating a floodlight.

BACKGROUND

With the rapid development of lighting technology, floodlights have been widely used in various fields as an important lighting device. Their unique optical characteristics, such as highly diffused and non-directional light output, result in soft and transparent shadows when illuminating objects, making floodlights particularly suitable for places that require uniform illumination.
Related floodlights on the market are designed to be fixed, which means that regardless of the application scenario, the size and shape of the light beam they produce remain constant. However, in practical use, different lighting needs often require different beam angles. These fixed-beam floodlights are inadequate in meeting diverse lighting requirements.
Therefore, there is a need for adjustable beam angles in floodlights.

The accompanying drawings show preferred embodiments of the present application. However, the present application can be realized in various forms, which are not limited to the embodiments described herein. The embodiments are provided to enable the present application to be understood more thoroughly and comprehensively.

Therefore, the above-mentioned terminologies shall not be interpreted as confine to the present application.
It is understandable that the term "a" should be understood as "at least one" or "one or more". In other words, in one embodiment, the number of an element can be one and in other embodiment the number of the element can be greater than one. The term "a" is not construed as a limitation of quantity.
In the description of the present application, it should be noted that the terms "mounted," "connected," "attached," and "linked" should be understood in a general manner, which could be, for example, affixedly connected, detachably connected, or integrally connected. Unless expressly specified and defined otherwise, it may also be a mechanical connection, an electrical connection or may be in communication with each other; it may be directly connected or indirectly connected by means of an intermediate medium, and may be an interaction relationship between two or more elements inside the two elements. For a person of ordinary skill in the art, the specific meanings of the above terms in the present application may be understood according to specific situations.
It should be noted that when an element is "fixed" to another element, it means that the element is directly arranged on the element, or an intermediate element is arranged therebetween. When an element is "connected" to another element, it means that the element is directly connected to the element, or an intermediate element is arranged therebetween. Furthermore, the term "and/or" is merely a description of an associative relationship between associated objects and indicates that three relationships may exist. For example, A and/or B means that A exists alone, both A and B exist, and B exists alone.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by any ordinary skilled person in the art. Terms in the specification of the present application are used only for the illustrative purposes only. For example, "in," "out," "left," "right," and similar expressions are used for illustrative purposes only, and are not intended to limit the present application.
To facilitate the description of "a first direction X" and "a second direction Z" in this embodiment, the term "a first direction X" refers to a left-right direction shown in the accompanying drawings, while the term "a second direction Z" refers to a front-back direction shown in the accompanying drawings. In this application, the arrow direction of the x-axis represents the "right" direction in the subsequent text, and the arrow direction of the z-axis represents the "back" direction in the subsequent text. However, these designations are not limiting in the actual application.
In the case of a related floodlight, achieving different beam angles requirements typically involves replacing lenses. However, this embodiment provides a floodlight that may adjust the beam angle, power, and color temperature of the floodlight without the need to replace the lens. This reduces the difficulties associated with adjusting the beam angle, color temperature, and power of related floodlights. By employing professional lens design, arranging and proportioning different angles of emitting surfaces (bulges) arrangement and implementing a reasonable circuit control, the angle adjustment of the luminaire may be easily achieved within the same product. Furthermore, by using a different ratio of light beads with varying color temperatures within a single bulge, mixed color temperatures may be achieved. This expands the range of applications for the product, eliminates the need for excessive mold investment, reduces product development costs, and meets diverse functional needs of consumers.
As shown in Figs. 1 to 12, schematic views of the floodlight 100 of the present application are presented. The floodlight 100 comprises a light emitting substrate 110, a first light emitting component 111, a second light emitting component 112, a lens respectively covered on the first light emitting component 111 and the second light emitting component 112, and an electronic control module for controlling the first light emitting component 111 and the second light emitting component 112. In this embodiment, the first light emitting component 111 and the second light emitting component 112 are arranged on the light emitting substrate 110. The first light emitting component 111 comprises a first light emitter 121 and a second light emitter 122, while the second light emitting component 112 comprises a third light emitter 123 and a fourth light emitter 124. The light emitted from the first light emitting component 111 and the second light emitting component 112 passes through the lens and forms a light beam. The electronic control module is electrically connected to the first light emitting component 111 and the second light emitting component 112, and comprises a control switch 131. The control switch 131 comprises a first switch 141 used to regulate the power of both the first light emitting component 111 and the second light emitting component 112. This enables control over the intensity of the projected light beam.
Referring to Figs. 1-2. the floodlight 100 comprises a housing 113 with an electrical compartment 14a, and the electronic control module further comprises a main control board 114 and a power supply 115 received in the electrical compartment 14a. The control switch 131 is mounted on the main control board 114 and electrically connected to it. The power supply 115 is installed on one side of the main control board 114 inside the electrical compartment 14a and is electrically connected to the first light emitting component 111, the second light emitting component 112, and the main control board 114. The main control board 114 responds to user instructions of the first switch 141 by converting the instructions into electrical signals, thereby controlling the power levels of the first light emitting component 111 and the second light emitting component 112. The first switch 141 of the control switch 131 has three adjustment modes. By switching between different adjustment modes of the first switch 141, a light emission power of the first light emitting component 111 and the second light emitting component 112 may be adjusted, thus adjusting a brightness of the floodlight 100. Different power levels correspond to different operating currents, which result in different light emission powers of the floodlight 100. By switching between different adjustment modes, users can control the operating currents of the floodlight 100, thus adjusting its light emission power.
Referring to Figs. 1-2, the first switch 141 comprises a first adjustment mode, a second adjustment mode, and a third adjustment mode. When switched to the first adjustment mode, the floodlight 100 emits light according to a first power level. When switched to the second adjustment mode, the floodlight 100 emits light according to a second power level. When switched to the third adjustment mode, the floodlight 100 emits light according to a third power level. Furthermore, by setting the first adjustment mode, the second adjustment mode, and the third adjustment mode, the light emission power of the floodlight 100 may be switched among the first power level, the second power level, and the third power level, allowing for easy, convenient, and efficient control. In an embodiment of this application, the first power is 175W, the second power is 145W, and the third power is 115W.
Referring to Fig. 1-2, the control switch 131 further comprises a second switch 142. The second switch 142 is configured to control the number of the opening or extinguishing of the first light emitting component 111 and the second light emitting component 112, thereby further controlling a beam angle of the light beam.
Referring to Fig. 3-4, the first light emitting component 111 emits a first beam 11a outward through the lens, and the second light emitting component 112 emits a second beam 11b outward through the lens. The second switch 142 is used to control the opening or extinguishing of the first light emitting component 111 and the second light emitting component 112, so that the light emitted by the floodlight 100 only comprises either the first beam 11a or the second beam 11b, or a mixed beam containing both the first beam 11a and the second beam 11b.
Referring to Fig. 3-4, the lens comprises a first lens body 116 covered on the first light emitting component 111 and a second lens body 117 covered on the second light emitting component 112. The first lens body 116 is aligned with a first direction X, and the second lens body 117 is aligned with a second direction Z. Since the first direction X is substantially perpendicular to the second direction Z, the beam angle of the first beam 11a formed by the light emitted from the first light emitting component 111 passing through the first lens body 116 differs from that of the second beam 11b formed by the light emitted from the second light emitting component 112 passing through the second lens body 117.
Referring to Fig. 3-4, the first lens body 116 is recessed inward to form a first groove 12a. The second lens body 117 is also recessed inward to form a second groove 12b. In this embodiment, the first groove 12a extends along the first direction X on one side of the first lens body 116, and the second groove 12b extends in the same direction as the first groove 12a on one side of the second lens body 117. However, due to the different orientations of the installation positions of the first lens body 116 relative to the first light emitting component 111 and the second lens body 117 relative to the second light emitting component 112, the curvature of the first lens body 116 differs that of the second lens body 117. This difference also results in different focal lengths for the first lens body 116 and the second lens body 117, thereby leading to different beam angles for the first beam 11a formed by the light passing through the first lens body 116 from the first light emitting component 111 and the second beam 11b formed by the light passing through the second lens body 117 from the second light emitting component 112.
Referring to Figs. 7-12, the beam angle of the first beam 11a formed by the light passing through the first lens body 116 of the first light emitting component 111 and the beam angle of the second beam 1 1b formed by the light passing through the second lens body 117 of the second light emitting component 112 differ in both the first direction X and the second direction Z. The light beams create curved spots in both directions, resulting in varying beam angles for the first beam 11a and the second beam 11b in both the first direction X and the second direction Z.
In this embodiment, the light beam angle V1 of the first beam 11a along the first direction X ranges from 40° to 50°, and the light beam angle V2 of the first beam 11a along the second direction Z ranges from 130° to 150°. Similarly, the light beam angle V3 of the second beam 11b along the first direction X ranges from 50° to 60°, and the light beam angle V4 of the second beam 11b along the second direction Z ranges from 100° to 120°.
The first beam 11a and the second beam 11b can be projected individually or combined to form a third light beam 11c. The light beam angle V5 of the third light beam 11c along the first direction X ranges from 45° to 55°, and the light beam angle V6 of the third light beam 11c along the second direction Z ranges from 115° to 135°.
Referring to Figs. 7-8, the second switch 142 comprises three beam modes: a first beam mode, a second beam mode, and a third beam mode. When the user switches to the first beam mode, the floodlight 100 emits light based on the beam angle formed by the first beam 11a. When the floodlight 100 emits light only within the beam angle range formed by the first beam 11a, all the first light emitting components 111 are turned on, and all the second light emitting components 112 are turned off. The light emission angle of the floodlight 100 along the first direction X corresponds to the beam angle within the range of the first beam 11a along the first direction X, denoted as beam angle V1. Similarly, the light emission angle of the floodlight 100 along the second direction Z corresponds to the beam angle within the range of the first beam 11a along the second direction Z, denoted as beam angle V2.
Referring to Figs. 9-10, when the user switches to the second beam mode, the floodlight 100 emits light based on the beam angle formed by the second beam 11b. When the floodlight 100 emits light only within the beam angle range formed by the second beam 11b, all the second light emitting components 112 are turned on, and all the first light emitting components 111 are turned off. When the floodlight 100 emits light within the beam angle range formed by the second beam 11b, the light emission angle of the floodlight 100 along the first direction X corresponds to the beam angle within the range of the second beam 11b along the first direction X, denoted as beam angle V3. Similarly, the light emission angle of the floodlight 100 along the second direction Z corresponds to the beam angle within the range of the second beam 11b along the second direction Z, denoted as beam angle V4.
Referring to Figs. 11-12, when the user switches to the third beam mode, the floodlight 100 emits light based on the beam angle formed by the third beam 11c. When the floodlight 100 emits light within the beam angle range formed by the third beam 11c, all the first light emitting components 111 and the second light emitting components 112 are turned on, causing the first beam 11a and the second beam 11b to merge and interweave after being projected outward, thus forming the mixed third beam 11c. Additionally, when the floodlight 100 emits light within the beam angle range formed by the third beam 11c, the light emission angle of the floodlight 100 along the first direction X corresponds to the beam angle within the range of the third beam 11c along the first direction X, denoted as beam angle V5. Similarly, the light emission angle of the floodlight 100 along the second direction Z corresponds to the beam angle within the range of the third beam 11c along the second direction Z, denoted as beam angle V6.
By setting the first beam mode, the second beam mode, and the third beam mode, the floodlight 100 may emit light at an angle close to the preset beam angle when the number of activated first light emitting components 111 and second light emitting components 112 is in a predetermined ratio. The second switch 142 may be used to control the number of activated first light emitting components 111 and second light emitting components 112, thereby controlling the light emission angle of the floodlight 100 without the need to replace the lens or the floodlight 100 itself. This control method is simple, convenient, and efficient.
When the floodlight 100 emits light using a mixture of the first light emitting component 111 and the second light emitting component 112, additional beam modes with different beam angles may be set. This allows the light emission angle and concentration of the beams projected by the floodlight 100 to vary based on the ratio of activated first light emitting components 111 and second light emitting components 112. As a result, the intensity of light in different regions of the emitted beam may differ, enabling adjustment of the light intensity in various areas while using the same power. Specifically, when the number of activated first light emitting components 111 increases and the number of activated second light emitting components 112 decreases, the light emission angle and concentration of the floodlight 100 will move closer to the beam angle and concentration of the first light emitting component 111. Conversely, when the number of activated first light emitting components 111 decreases and the number of activated second light emitting components 112 increases, the light emission angle and concentration of the floodlight 100 will move closer to the beam angle and concentration of the second light emitting component 112. By controlling the ratio of activated first light emitting components 111 and second light emitting components 112 through the second switch 142, the intensity of light in different areas of the floodlight 100 beam may be controlled, creating areas of high intensity and soft light, thereby improving the adaptability of the floodlight 100 in various scenarios.
The floodlight 100 further comprises an emission module and a lens module. The emission module comprises the first light emitting component 111 and the second light emitting component 112. The lens module comprises the first lens body 116 and the second lens body 117. The first lens body 116 and the second lens body 117 are integrally formed. The first light emitting component 111 and the second light emitting component 112 are arranged on the same circuit board.
The first light emitting component 111 and the second light emitting component 112 in the floodlight 100 are integrated into the same emission module, and all the first light emitting components 111 and all the second light emitting components 112 are controlled through the same integrated circuit. On one hand, this avoids the separate production of the first light emitting component 111 and the second light emitting component 112. With the production process of the integrated circuit, an emission module with multiple first light emitting components 111 and multiple second light emitting components 112 may be produced. This simplifies the production process and improves the consistency of the working conditions of the first light emitting component 111 and the second light emitting component 112 in the emission module. On the other hand, by using a unified integrated circuit to control multiple first light emitting components 111 and multiple second light emitting components 112, the second switch 142 may effectively and reliably manage the first light emitting component 111 and the second light emitting component 112. Furthermore, the first lens body 116 and the second lens body 117 in the floodlight 100 are integrated into the same lens module, enabling the first lens body 116 and the second lens body 117 to be formed at once. This simplifies the production process and improves the consistency between the first lens bodies 116 and the second lens bodies 117, thereby ensuring uniformity in the emitted light from all the first light emitting components 111 and all the second light emitting components 112. By making the curvature and focal length of the first lens body 116 and the second lens body 117 unequal, the beam angle of the first beam 11a after passing through the first lens body 116 and the beam angle of the second beam 11b after passing through the second lens body 117 of the first light emitting component 111 and the second light emitting component 112, respectively, will not be equal. This allows for controlling the floodlight 100's beam angle by managing the number of activated first light emitting components 111 and second light emitting components 112, providing convenience in operating the floodlight 100.
The relationship between the center distance D of adjacent first lens body 116 and second lens body 117, the radius R1 of the first lens body 116, and the radius R2 of the second lens body 117 is configured as: D ≥ R1 + R2 + 1.5mm. Furthermore, due to the integral formation of the first lens body 116 and the second lens body 117 in the lens module, some light rays entering the first lens body 116 and the second lens body 117 will undergo refraction and reflection within the lens module before being emitted from the lens module. Therefore, if the center distance between the first lens body 116 and the second lens body 117 is too close, it will cause mixed light rays from the first lens body 116 and the second lens body 117 to be emitted from the lens module. The combined light rays will be a superposition of the beams from the first lens body 116 and the second lens body 117, resulting in differences in brightness compared to the beams emitted separately from the first lens body 116 and the second lens body 117. This may lead to ghosting and glare when using the floodlight 100, thereby affecting its lighting effect.
By configuring the relationship between the center distance D of adjacent first lens body 116 and second lens body 117, the radius R1 of the first lens body 116, and the radius R2 of the second lens body 117 as: D ≥ R1 + R2 + 1.5mm, it prevents the center distance between the first lens body 116 and the second lens body 117 from being too small, thus reducing the mixing of light rays entering the first lens body 116 and the second lens body 117. This helps to avoid ghosting and glare, improving the lighting effect of the floodlight 100.
In some embodiments of the present application, the relationship between the center distance D of adjacent first lens body 116 and second lens body 117, the radius R1 of the first lens body 116, and the radius R2 of the second lens body 117 is configured as: D <, R1 + R2 + 5mm. If the center distance between the first lens body 116 and the second lens body 117 is too large, it will result in a dispersed arrangement of the first light emitting component 111 and the second light emitting component 112, thereby reducing the overall brightness of the floodlight 100. By configuring the relationship between the center distance D of adjacent first lens body 116 and second lens body 117, the radius R1 of the first lens body 116, and the radius R2 of the second lens body 117 as: D ≤ R1 + R2 + 5mm, it prevents the distance between the first light emitting component 111 and the second light emitting component 112 from being too large, allowing the light beams emitted by the first light emitting component 111 and the second light emitting component 112 to be more concentrated, thus achieving the desired brightness of the floodlight 100.
Referring to Figs. 3-4, the first light emitting component 111 and the second light emitting component 112 are preferably arranged and installed individually on the light emitting substrate 110, as well as in a mixed arrangement on the light emitting substrate 110. Furthermore, the first light emitting component 111 and the second light emitting component 112 are mixedly arranged to form a first light column 13a, and the first light emitting component 111 and the second light emitting component 112 are individually arranged to form a second light column 13b. The first light column 13a is located between two second light columns 13b.
Referring to Figs. 3-4, in the first light column 13a, the number of the first light emitting component 111 is equal to the number of the second light emitting component 112. In this embodiment, two of the first light emitting components 111, and two of the second light emitting components 112 are used. The first light emitting components 111 and the second light emitting components 112 are respectively arranged in pairs in adjacent installation areas, which facilitates distinguishing and installing the first light emitting components 111 and the second light emitting components 112 from each other.
Referring to Figs. 3-4, the relationship between the quantity M of the first light emitting component 111 and the quantity N of the second light emitting component 112 is configured as follows: M = N. In this embodiment, the quantity M = N = 12 for the first light emitting component 111. Among these 12 first light emitting components 111, 10 are divided into two columns of 5 each, forming two columns of the second light column 13b. Similarly, the quantity of the second light emitting component 112 is also 12, with 10 divided into two columns of 5 each, forming two columns of the second light column 13b. The remaining two first light emitting components 111 and the remaining two second light emitting components 112 are combined to form a column of the first light column 13a. A represent the number of columns in which the first light emitting component 111 is arranged separately, B represent the number of columns containing the second light emitting component 112 arranged separately, and C denote the number of columns where both components are mixed. Thus, it can be understood that A: B: C = 2:2:1.
Referring to Figs. 1 and 3-4, the light emitting substrate 110 is provided with installation areas that correspond to the quantities of the first light emitting component 111 and the second light emitting component 112. Specifically, each first light emitting component 111 has a corresponding installation area, as does each second light emitting component 112. By assembling the first light emitting component 111 and the second light emitting component 112 onto their respective predetermined installation areas on the light emitting substrate 110, a matrix structure 14a is formed, where multiple matrix structures 14a combine to form a square structure on the light emitting substrate 110, resulting in the luminous surface of the floodlight.
In this embodiment, one matrix structure 14a comprises two columns of the second light column 13b formed by the first light emitting component 111, two columns of the second light column 13b formed by the second light emitting component 112, and one column of the first light column 13a formed by the combination of the first light emitting component 111 and the second light emitting component 112. The second light column 13b and the first light column 13a are alternately arranged, starting with the arrangement of the second light column 13b formed by the first light emitting component 111, followed by the arrangement of the second light column 13b formed by the second light emitting component 112, then the arrangement of the first light column 13a formed by the combination of the first light emitting component 111 and the second light emitting component 112, and finally, the arrangement of the second light column 13b formed by the second light emitting component 112.
Furthermore, the quantity of the second light column 13b is twice that of the first light column 13a. Due to the different beam angles of the light emitting components (with larger beam angles leading to more dispersed beams), the brightness of the light emitted by components with different beam angles varies. By alternating the arrangement of the first light emitting component 111 and the second light emitting component 112, the distribution of these components in the floodlight 100 becomes more uniform. Additionally, by mixing the first light emitting component 111 and the second light emitting component 112 to form the first light column 13a and positioning it between two second light columns 13b, the impact of brightness differences between the first light emitting component 111 and the second light emitting component 112 on the illumination effect of the floodlight 100 is reduced, resulting in improved uniformity of the illuminated beam.
Additionally, in an alternative embodiment, the first light emitting component 111 and the second light emitting component 112 may be individually arranged and installed on the light emitting substrate 110 to cater to different types of floodlights 100 based on user requirements.
Referring to Figs. 1-2, the control switch 131 further comprises a third switch 143. The third switch 143 is configured to control the ratio of the quantities of the first light emitter 121 and the second light emitter 122 that are turned on or off, as well as the ratio of the quantities of the third light emitter 123 and the fourth light emitter 124 that are turned on or off, in order to manage the color temperature of the light beam emitted outward.
The color temperature of the first light emitting component 111 may be controlled by adjusting the ratio of the quantities of the first light emitter 121 and the second light emitter 122 that are turned on. This allows for control of the overall color temperature of the floodlight 100, thereby expanding the range of color temperature adjustment. Additionally, during production settings, the color temperature of the first light emitter 121 may be set differently from the color temperature of the second light emitter 122. By controlling the ratio of the quantities of the first light emitter 121 and the second light emitter 122, the color temperature of individual first light emitting components 111 may be managed.
Since the floodlight 100 emits light through the first light emitting component 111, any changes in its color temperature of the first light emitting component 111 will affect the overall color temperature of the floodlight 100. Therefore, by controlling the color temperature of the first light emitting component 111, it is possible to control the color temperature of the floodlight 100.
Referring to Fig. 6, within each individual second light emitting component 112, the color temperature may also be controlled by adjusting the ratio of the quantities of the third light emitter 123 and the fourth light emitter 124 that are turned on. By controlling the color temperature of the second light emitting component 112, the overall color temperature of the floodlight 100 may be adjusted, thereby expanding the range of color temperature adjustment for the floodlight 100.
Additionally, during production settings, the color temperature of the third light emitter 123 may be set differently from the color temperature of the fourth light emitter 124. By controlling the ratio of the quantities of the third light emitter 123 and the fourth light emitter 124, the color temperature of individual second light emitting components 112 may be controlled.
Since the floodlight 100 emits light through the second light emitting component 112, any changes in its color temperature of the second light emitting component 112 will affect the overall color temperature of the floodlight 100. Therefore, by controlling the color temperature of the second light emitting component 112, it is possible to control the color temperature of the floodlight 100.
By controlling the on/off states of all the first light emitters 121 and the second light emitters 122 in an installation area of the first light emitting component 111, the on/off states of the first light emitting component 111 may be controlled. This results in a change in the number of first light emitting components 111 that are turned on, thereby altering the brightness of the floodlight 100. By controlling the on/off state of the first light emitter 121, the second light emitter 122, the third light emitter 123, and the fourth light emitter 124, the on/off state of both the first light emitting component 111 and the second light emitting component 112 may be controlled. Since the first beam 11a passes through the first lens body 116, and the second beam 11b passes through the second lens body 117, it may be understood that users may also control the output angle of the floodlight 100 by adjusting the ratio of the on/off states between the first light emitter 121 and the second light emitter 122. This enhances the flexibility and adjustability of the floodlight 100.
In another embodiment of the present application, the second light emitting component 112 is identical to the first light emitting component 111. By making the first light emitting component 111 and the second light emitting component 112 identical (i.e., making the third light emitter 123 identical to the first light emitter 121, and the fourth light emitter 124 identical to the second light emitter 122), all the first light emitting components 111 and the second light emitting components 112 of the floodlight 100 will tend to be consistent, thus promoting efficiency in the production process of the overall floodlight 100.
Referring to Figs. 1-2, the third switch 143 is configured with three color temperature modes. Each color temperature mode corresponds to a different ratio of open/close states for the first light emitter 121 and the second light emitter 122. By switching between different color temperature modes using the third switch 143, the ratio of open/close states for the first light emitter 121 and the second light emitter 122 in the first light emitting component 111, as well as the ratio of open/close states for the third light emitter 123 and the fourth light emitter 124 in the second light emitting component 112, may be controlled. This allows for control of the color temperature of both the first light emitting component 111 and the second light emitting component 112, thereby controlling the color temperature of the floodlight 100.
In an embodiment of this application, in each first light emitting component 111: the relationship between the quantity m of the first light emitter 121 and the quantity M of the second light emitter 122 is configured as 2M≤m≤4M. Furthermore, the first light emitter 121 and the second light emitter 122 are mixed and arranged to form a first mixed light row 15a. The quantity of the first light emitter 121 in the first mixed light row 15a is set to one or two, and the quantity of the second light emitter 122 is set to two or four. Specifically, when the quantity of the first light emitter 121 is set to one, the quantity of the second light emitter 122 is four; when the quantity of the first light emitter 121 is two, the quantity of the second light emitter 122 is two. Moreover, when both the first light emitter 121 and the second light emitter 122 have a quantity of two, the first mixed light row 15a is placed between the remaining first mixed light rows 15a. Additionally, the third light emitter 123 and the fourth light emitter 124 are mixed and arranged to form a second mixed light row 15b. The quantity of the first light emitter 121 in the second mixed light row 15b is set to one or two, and the quantity of the second light emitter 122 is set to two or four. Specifically, when the quantity of the third light emitter 123 is set to one, the quantity of the fourth light emitter 124 is four; when the quantity of the third light emitter 123 is two, the quantity of the fourth light emitter 124 is two. Moreover, when both the third light emitter 123 and the fourth light emitter 124 have a quantity of two, the second mixed light row 15b is placed between the remaining second mixed light rows 15b.
In each first light emitting component 111, the relationship between the quantity E of the first light emitter 121 and the quantity F of the second light emitter 122 is configured as: E=3F. The relationship between the quantity U of the third light emitter 123 and the quantity E of the first light emitter 121 is configured as: U=E. Similarly, the relationship between the quantity V of the fourth light emitter 124 and the quantity F of the second light emitter 122 is configured as: V=F.
In each first light emitting component 111, the color temperature t of the first light emitter 121 is configured as: 2500K≤t≤3500K, and the color temperature T of the second light emitter 122 is configured as: 6000K≤T≤7000K.
In each second light emitting component 112, the color temperature q of the third light emitter 123 is configured as: 2500K≤q≤3500K, and the color temperature Q of the fourth light emitter 124 is configured as: 6000K≤Q≤7000K.
According to the principle of color mixing for light, when different color temperatures of light beams are mixed, a new color temperature of the resulting beam is generated, and the quantity of light beams with different color temperatures will affect the resulting color temperature. Therefore, by configuring the quantity and color temperature of the first light emitter 121 and the second light emitter 122, the color temperature of the first light emitting component 111 may be adjusted. Similarly, by configuring the quantity and color temperature of the third light emitter 123 and the fourth light emitter 124, the color temperature of the second light emitting component 112 may be adjusted. Thus, the color temperature of the floodlight 100 may be controlled using the third switch 143, providing a simple, convenient, and fast control method.
The color temperature of the first light emitter 121 is configured as 3000K, and the color temperature of the second light emitter 122 is configured as 6500K. According to the principle of color mixing for light, if all the first light emitters 121 and all the second light emitters 122 are turned on in the first light emitting component 111, the color temperature of the first light emitting component 111 will be 4000K. If only the first light emitter 121 is turned on in the first light emitting component 111, the color temperature will be 3000K. Conversely, if only the second light emitter 122 is turned on, the color temperature will be 6500K.
In an application of this disclosure, in a single first light emitting component 111, the first light emitter 121 has a color temperature of 3000K, the second light emitter 122 has a color temperature of 6500K, and the ratio of the quantity of the first light emitter 121 to the second light emitter 122 is set as 3:1. When the third switch 143 is switched to a first color temperature mode, only the first light emitter 121 in the first light emitting component 111 is turned on, resulting in a color temperature of 3000K for the first light emitting component 111. Since the floodlight 100 emits light through the first light emitting component 111, the color temperature of the floodlight 100 will also be 3000K. Similarly, when the third switch 143 is switched to a second color temperature mode, only the second light emitter 122 in the first light emitting component 111 is turned on, resulting in a color temperature of 6500K for the first light emitting component 111. The floodlight 100 will then emit light with a color temperature of 6500K. Furthermore, when the third switch 143 is switched to a third color temperature mode, all the first light emitters 121 and all the second light emitters 122 in the first light emitting component 111 are turned on, resulting in a color temperature of 4000K. The floodlight 100 will emit light with a color temperature of 4000K. It may be understood that the process principles for the third light emitter 123 and the fourth light emitter 124 in the second light emitting component 112 are similar to those of the first light emitting component 111 but with different quantities.
