Description

Light source system with adjustable light source mode

Technical Field

The invention relates to the technical field of stage lighting, in particular to a light source system with an adjustable light source mode.

Background

The existing high-power stage lighting light source is gradually replaced by a high-power LED light source, and a common stage lighting light source module is a white light LED array light source module. The common white light LED array light source module mainly comprises an LED array formed by arranging a single LED chip array, a collimating lens array formed by arranging and combining a lens unit array, and a condenser lens for converging collimated light beams. The collimating lens array and the condenser lens are sequentially arranged in the light emitting direction of the LED array. The lens units on the collimating lens array correspond to the LED chips on the LED array one by one, so that light rays emitted by the LED chips are collimated and collimated into near-parallel light rays, and the near-parallel light rays are focused on a preset surface to form focusing light spots after being converged by the condenser lens.

The existing collimating lens array and the LED array are both fixedly arranged, so that the lens unit is aligned to the optical center of the LED chip, and the optimal collimating effect is achieved. However, the color temperature, color, shape, etc. of a single LED chip are all single effects, and therefore, it is not possible to realize a light spot effect that presents different color temperatures, colors, or shapes on the same light source module. However, if two or more LED chips are disposed on one chip unit to correspond to one lens unit, the lens unit cannot align with the optical center of one of the LED chips for optimal collimation. Therefore, the existing LED array light source module usually provides a light source module with a color temperature, and different light source modules are usually required to achieve different color temperature effects, i.e. one light source module cannot achieve the light emitting effect with different color temperatures.

Disclosure of Invention

The present invention is directed to overcome at least one of the above-mentioned drawbacks of the prior art, and provides a light source system with adjustable light source mode, wherein the light source system includes a plurality of light emitting chips, and can achieve different light emitting effects.

The technical scheme adopted by the invention is as follows:

a light source system with adjustable light source modes, comprising:

the LED array is provided with a plurality of LED chip groups which are arranged in an array manner, and the LED array emits a first light beam;

the collimating lens device is provided with a plurality of lens units and is used for collimating the first light beam emitted by the LED array to emit a second light beam;

the position adjusting device is connected with the LED array or the collimating lens device and is used for displacing the collimating lens device or the LED array;

the focusing lens is arranged in the light outgoing direction of the collimating lens device and is used for converging the second light beam;

the at least one LED chip group comprises at least two different LED chip units, so that the first light beam comprises at least two first light rays;

the collimating lens device and the LED array can generate relative displacement under the action of the position adjusting device, so that the collimating lens device can collimate different first light rays, and different light spot effects are further presented.

In the technical scheme, the initial light emitting unit of the light source system is composed of the LED array, light beams emitted by the LED array are first light beams, the first light beams are Lambert-type light beams, and the divergence angle is large. The first light beam is collimated by the collimating lens device and then emits light to form a second light beam, the second light beam collimated by the collimating lens device is near-parallel light, the light rays generally face the same direction, and the second light beam is converged by the focusing lens and then focused on a preset surface to form a focusing light spot.

In this technical scheme, at least one LED chipset contains two kinds of different LED chip units at least to make first light beam include two kinds at least first light, through adjusting collimating lens device and LED array's relative position, can make the lens unit on the collimating lens device aim at different LED chip units, thereby make the lens device can carry out the collimation to different first light, show different facula effect after focusing lens assembles again. Therefore, the technical scheme has the effect of realizing different light modes on the same light source module.

Under the condition that at least one LED chip group comprises at least two different LED chip units, other LED chip groups of the technical scheme can be composed of a single LED chip unit, can also be formed by combining 2 or more LED chip units, can also be composed of a part of a single LED chip unit, and can also be composed of at least two LED chip units. According to the technical scheme, different light spot effects can be realized as long as one LED chip group comprises at least two different LED chip units.

Specifically, when a part of LED chips in the LED array are lit to make the LED array emit a first light beam of a first type, a lens unit in the collimating lens device is aligned with the lit LED chips to collimate the first light beam emitted by the LED array, emit a second light beam of the first type after collimation, and present a first light spot through the focusing lens; when another part of LED chips in the LED array are lightened, the collimating lens device or the LED array is adjusted through the position adjusting device, so that the lens unit in the collimating lens device is aligned to the lightened LED chips, the first light beams of the second type emitted by the LED chips are collimated, the second light beams are emitted, and another light spot is presented through the focusing lens. Similarly, if the LED chip set includes more LED chip units, more light spot effects can be exhibited. According to the technical scheme, the relative position of the collimating lens device and the LED array is controlled, so that the lens unit on the collimating lens device can be aligned to different LED chips, the collimating lens device can collimate light emitted by different LED chips, and a light source system can have multiple light effects.

Because at least one LED chip group comprises at least 2 different LED chip units, and the optical centers of the different LED chip units have a certain distance, therefore, in order to align the optical center of the LED chip unit emitting light to the lens unit, the technical scheme is provided with the position adjusting device which can be connected with the LED array, and the LED chip unit emitting the first light beam is aligned to the lens unit by moving the LED array. The position adjusting device can also be connected with the collimating lens device, and the lens unit of the collimating lens device is aligned to the LED chip unit emitting the first light beam by moving the collimating lens device. The position of the LED array or the collimating lens device is adjusted and moved by the position adjusting device, so that the optical center of the lens unit is aligned to different LED chip units to present different light spot effects.

Further, the position adjusting device is a driving mechanism for driving the LED array or the collimating lens device to displace. The drive mechanism may be selectively coupled to the LED array or the collimating lens arrangement.

Further, the driving mechanism is an electric driving type driving mechanism or a mechanical driving type driving mechanism.

The electric driving type driving mechanism can be a telescopic control device, and the LED array or the collimating lens device is controlled by a motor to move in a telescopic mode, so that the displacement of the LED array or the collimating lens device is controlled. Specifically, the telescopic control device comprises a telescopic rod, and the telescopic rod is arranged between the telescopic control device and the LED array or the collimating lens device. Alternatively, the driving mechanism may be a mechanical driving type driving mechanism, and the displacement of the LED array or the collimating lens device can be controlled through mechanical movement or manual control.

Further, specifically, the telescoping control device may be a stepping motor, and the moving distance of the stepping motor is controllable, so that the LED array or the collimator lens device may be controlled to move within a small distance range, and the moving distance of each time is consistent.

Further, the LED array or the collimating lens device also comprises a guiding and sliding mechanism for directional displacement. Furthermore, the sliding guide mechanism is arranged on two side edges of the LED array or the collimating lens device and is used for assisting the LED array or the collimating lens device to slide in the moving direction, so that the LED array or the collimating lens device can move more smoothly and conveniently.

Further, the slide guiding mechanism is a sliding chute or a sliding rail. The sliding groove or the sliding rail is simple in structure and has a good guiding effect. Under the drive of the driving mechanism, the LED array or the collimating lens device can slide on the sliding groove or the sliding rail, so that the LED array or the collimating lens device can be rapidly and accurately moved to a set position.

Furthermore, the LED collimating lens device further comprises limiting blocks arranged at two end parts of the guide sliding mechanism and used for limiting the moving stroke of the LED array or the collimating lens device.

The limiting blocks are arranged at two ends of the guide sliding mechanism, so that the movement of the LED array or the collimating lens device is better limited.

Further, the position adjusting device adjusts the stroke of each displacement of the LED array or the collimating lens device to be 0.1-5mm.

The stroke of each displacement of the LED array or the collimating lens device is mainly determined by the distance between the center points of the two LED chip units in the LED chip group. The distance between the central points of the two chip units is generally in the range of 0.1-5mm, and if the distance is too small, the requirement on the chip is too high and the heat dissipation is not good; if the distance is too large, the area of the entire LED array becomes large. Therefore, the distance between the central points of the two chip units is generally in the range of 0.1-5mm, and the stroke of each displacement of the LED array or the collimating lens device is adjusted to be 0.1-5mm by the position adjusting device.

Further, the collimating lens device comprises a first collimating lens structure, a second collimating lens structure and a lens support, the first collimating lens structure is provided with a plurality of first lenses, the second collimating lens structure is provided with a plurality of second lenses, the first lenses and the second lenses are in one-to-one correspondence, and the first collimating lens structure and the second collimating lens structure are installed on the lens support.

When the LED array emits light, the first light beams sequentially pass through the first lens and the second lens to emit light, and the LED chips, the first lens and the second lens are in one-to-one correspondence so as to collimate the first light beams. The first light beam can be a light beam emitted by one or more LED chip units in the LED chip group.

Further, the LED array is mounted on the LED substrate.

Further, the position adjusting device is connected with the lens support or the LED substrate.

When the position adjusting device is connected with the lens support, the lens unit on the straight lens device can be displaced by moving the lens support, so that the lens unit is aligned with the first light beam. When the position adjusting device is connected with the LED substrate, the LED chip units on the LED substrate can be displaced by moving the LED substrate, so that the LED chip units emitting the first light beams are aligned with the lens units on the collimating lens device.

Further, the single LED chip group at least comprises two LED chip units, and the LED chip units or the lens unit can be relatively displaced under the action of the position adjusting device, so that the lens unit can be aligned with the optical centers of different LED chip units.

In the technical scheme, each LED chip group is further limited to at least comprise two LED chip units, and different LED chip units emit different light beams, so that different light spot effects are formed on the same light source module. Specifically, when each LED chip group includes two LED chip units, assuming that the LED chip units are a first LED chip and a second LED chip, respectively, when the first LED chip of each LED chip group is turned on and the second LED chip is turned off, the lens units on the collimating lens device are aligned with the first LED chip through the position adjustment device, so as to obtain a light source with a first light efficiency. When the first LED chip is turned off and the second LED chip is turned on, the lens units on the collimating lens device are respectively aligned to the second LED chip through the position adjusting device, and a light source with a second lighting effect is obtained. Similarly, when each LED chip group comprises three or more LED chip units, a light source with 3 or more light effects can be obtained. Two or more than two LED chip units can be arranged in a transverse linear mode or in a longitudinal linear mode. When the LED chip group contains a plurality of LED chip units, the LED chip units can be transversely and longitudinally arranged in a uniform linear mode and also can be uniformly distributed in an array mode, and only the position adjusting device needs to be adjusted to enable the lens unit of the collimating lens device to be capable of aligning different LED chip units on the LED chip group.

Furthermore, the LED chip unit is a single LED chip or is formed by combining a plurality of LED chips.

In this technical solution, when the LED chip unit is a single LED chip, each LED chip group may be composed of two or more LED chips, and when the LED chips are linearly arranged, the position adjusting device controls the distance that the LED array or the collimating lens device moves to be the distance between the center points of the two LED chips. When the LED chip unit is formed by combining a plurality of LED chips, that is, the plurality of LED chips are combined to form one LED chip unit, for example, when two LED chips are combined to form one LED chip unit and the LED chip group includes two LED chip units, a total of 4 LED chips are provided in one LED chip group, and the distance that the position adjustment device controls the LED array or the collimating lens device to move is the distance between the centers of the two LED chip units. In addition, in the technical solution, the combination type of the LED chip units in one LED chip group is not limited, for example, one LED chip group includes two LED chip units, one of the LED chip units may include a single LED chip, and the other LED chip unit may include a combination of a plurality of LED chips.

Further, the LED chip group includes n × m LED chip units, where n is the number of LED chip units arranged in the transverse direction, and m is the number of LED chip units arranged in the longitudinal direction; n or m is greater than or equal to 2,n and m is an integer. In the technical scheme, the LED chip units can be regularly arranged in the transverse direction and the longitudinal direction, and the LED array and the collimating lens device can be subjected to relative displacement in the transverse direction and the longitudinal direction through the position adjusting device, so that the lens unit and the LED chip units which can be selectively aligned to different LED chip units in the transverse direction and the longitudinal direction can be obtained.

Furthermore, the LED chip unit is a single LED chip or is composed of a plurality of LED chips.

Further, the LED chip group comprises p × q LED chips, wherein both p and q are greater than or equal to 3, and p is the number of the LED chip units which are transversely arranged; q is the number of longitudinally arranged LED chips; r LED chips adjacent in the transverse direction are combined into a common comprehensive optical center and/or s LED chips adjacent in the longitudinal direction are combined into a common comprehensive optical center, or r multiplied by s LED chips are combined into a common comprehensive optical center; wherein r is more than or equal to 2 and less than p, s is more than or equal to 2 and less than q, and p, q, r and s are integers. In the technical scheme, the LED chip unit in the LED chip group can be formed by combining 2 or more transversely adjacent LED chips, can also be formed by combining 2 or more longitudinally adjacent LED chips, and can also be formed by combining r multiplied by s LED chips together.

Further, the LED lamp also comprises a control unit, wherein the control unit is electrically connected with the LED chip units, and the control unit independently controls the brightness of each LED chip unit.

In the technical scheme, the control unit independently controls each LED chip unit so as to present different light spot effects. For example, each LED chip group is provided with a first LED chip unit and a second LED chip unit, the first LED chip unit and the second LED chip unit may be both composed of a single LED chip, and the difference between the two may be a color or a color temperature, and when the control unit independently controls the first LED chip units of each LED chip group to be turned on, light spots of the color or the color temperature of the first LED chip are presented; when the control unit independently controls the second LED chip units of each group of LED chip groups to be lightened, light spots of the color or the color temperature of the second LED chips are presented. In addition, the LED chip units can also have the difference of the number of the LED chips, so that light spots with different brightness can be presented. Each LED chip group may further include a plurality of LED chip units to exhibit various light spot effects.

Further, the device also comprises a light homogenizing device arranged between the collimating lens device and the focusing lens, and the light homogenizing device homogenizes the second light beam emitted by the collimating lens device.

Preferably, the light homogenizing device is a fly eye lens or a light homogenizing or diffusing sheet.

Compared with the prior art, the invention has the following beneficial effects:

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

As shown in fig. 1, the present embodiment discloses a light source system with adjustable light source mode, which includes an LED array 21, a collimating lens device 22, and a focusing lens 23. The LED array 21 emits a first light beam, and the collimating lens device 22 is provided with a plurality of lens units for collimating the first light beam emitted by the LED array 21 to emit a second light beam; and the focusing lens 23 is arranged in the light outgoing direction of the collimating lens device 22, and is used for converging the second light beam and focusing the second light beam on a preset surface to form a focusing light spot 24.

Referring to fig. 2, the LED array 21 has a plurality of LED chip sets arranged in an array, and each LED chip set in this embodiment has 2 LED chip units, namely a first chip unit 211 and a second chip unit 212. In this embodiment, the first LED chip unit 211 and the second chip unit 212 are both single LED chips, the LED chips of the two LED chip units have different colors, and the two LED chips in each LED chip set are arranged in the same manner. It should be noted that fig. 1 and fig. 2 in this embodiment 1 only illustrate a case that the LED chip set includes 2 LED chip units, and each LED chip unit is a single LED chip, in fact, the LED chip set may further include three or more LED chip units, and the LED chip unit may also be composed of a plurality of LED chips. Since the embodiments cannot be exhaustive, the present application does not develop the embodiments for these situations in detail, but the designs of various LED chip units and multiple LED chips also belong to the protection scope of the present application. The LED chip units may be LED chips with different colors, or LED chips with different color temperatures, or LED chips with different light emitting powers.

The present embodiment further includes a control unit (not shown in the figure) for controlling the brightness of each LED chip unit. Since each LED chip unit is different, the first light beam emitted from the LED array 21 is different. Specifically, when the control unit controls the first chip unit 211 to light up, the first chip emits a light beam as the first light beam on the LED array 21; when the control unit controls the second chip unit 212 to be turned on, the second chip emits another light, which is the first light beam on the LED array 21; when the control unit controls the first chip unit 211 and the second chip unit 212 to be turned on simultaneously, the first chip and the second chip emit light simultaneously, which is a first light beam on the LED array 21, and thus different light-emitting light beams are presented.

Specifically, the LED array 21 is mounted on an LED substrate.

As shown in fig. 1, the collimating lens device 22 is configured to collimate light beams emitted by the LED array 21, the collimating lens device 22 includes a first collimating lens structure 222, a second collimating lens structure 223 and a lens support 221, the first collimating lens structure 222 and the second collimating lens structure 223 are mounted on the lens support 221, and the first light beam is collimated by the first collimating lens structure 222 and the second collimating lens structure 223 in sequence and then emits a second light beam. Specifically, the first collimating lens structure 222 is provided with a plurality of first collimating lens units, the second collimating lens structure 223 is provided with a plurality of second collimating lens units, and the LED chip sets correspond to the first collimating lens units and the second collimating lens units one to one.

Because each LED chip group contains 2 different LED chip units, and 2 LED chip units control the selectivity light-emitting through the control unit, in order to make the first light beam on the LED array 21 aim at the lens unit optical center on the collimating lens device 22 and carry out collimation, this technical scheme has set up position control device, position control device is connected with LED base plate or lens support 221, through controlling LED base plate or lens support 221 to take place the displacement, thereby make collimating lens device 22 can carry out the collimation to different first light beams, demonstrate different facula effects.

Specifically, in the present embodiment, the position adjustment device is mounted on the lens holder 221 for displacing the collimator lens device 22. Preferably, the position adjustment means is a drive mechanism that drives the collimator lens arrangement 22 to be displaced. The driving mechanism may be an electrically driven driving mechanism or a mechanically driven driving mechanism.

Further, as shown in fig. 3, in the present embodiment, the driving mechanism is an electrically driven driving mechanism, and the displacement of the collimator lens device can be controlled more precisely by the operation of the electrically driven driving mechanism. Specifically, the driving mechanism is a telescopic control device 33, and the telescopic control device 33 is responsible for pushing the collimator lens device 22 to move. Specifically, the telescopic control mechanisms are respectively arranged on the left side and the right side of the lens support, a telescopic rod 331 is arranged between the telescopic control mechanisms and the lenses, when the telescopic control device 33 on the right side works, the telescopic rod 331 pushes the collimating lens device 22 to move leftwards, and when the telescopic control device 33 on the left side works, the telescopic rod 331 pushes the collimating lens device 22 to move rightwards, so that the first lens unit and the second lens unit on the collimating lens device 22 respectively correspond to the LED chip units emitting the first light beams on the LED array 21 one by one, and collimation is further performed.

Further, the two sides of the lens holder 221 are provided with slide guiding mechanisms, in this embodiment, the slide guiding mechanisms are slide rails 32 respectively disposed on the two sides of the lens holder 221, and when the collimator lens device 22 is pushed by the expansion control device 33, the collimator lens device 22 slides on the slide rails 32.

Further, two end portions of the slide guide mechanism are provided with stoppers 31 for limiting the moving stroke of the collimator lens device 22.

Specifically, the distance between the center points of the first chip unit 211 and the second chip unit 212 is 0.1-5mm, and therefore, the stroke of the collimator lens device 22 pushed by the expansion control device 33 is 0.1-5mm per shift. Since the distance between the first chip unit 211 and the second chip unit 212 is relatively small, the distance over which the collimator lens arrangement 22 is displaced is also relatively small. Therefore, other optical elements, such as the focusing lens 23, only need to be made a little bigger, and the light-emitting effect can still be ensured.

Fig. 3 shows only one of the LED chip arrangement and the adjustable collimating lens assembly 22, and from the visual point of view of fig. 3, the 2 LED chip arrangements are arranged in a transverse direction, so the adjustable collimating lens assembly 22 moves in a manner that the LED chips are arranged in a transverse direction. In fact, the LED chips may be arranged in a longitudinal direction, and the movable direction of the adjustable collimating lens device 22 may be adjusted to be arranged in a longitudinal direction. The arrangement of the LED chips may also be inclined as long as the movable direction of the collimating lens device 22 is adjusted to also vary with the arrangement direction of the LED chips.

In summary, the present embodiment includes the following light extraction schemes:

as shown in fig. 1, 2, and 3, taking the vision of fig. 2 and 3 as a position reference, when the control unit controls the first chip unit 211 to work, the telescopic control device 33 pushes the collimating lens device 22 to move left on the slide rail 32, so that the lens unit on the collimating lens device 22 aligns with the first chip of the first chip unit 211, and the first chip emits the first light beam 25, which is collimated by the lens unit to emit the first second light beam, and then the first light beam is converged by the focusing lens to present the first light spot effect.

As shown in fig. 4, when the control unit controls the second chip unit 212 to operate, the telescopic control device 33 pushes the collimating lens device 22 to move rightward on the slide rail 32, so that the lens unit on the collimating lens device 22 aligns with the second chip of the second chip unit 212, the second chip emits the second first light beam 26, the second first light beam is collimated by the lens unit to emit the second light beam, and the second light beam is converged by the focusing lens to present the second light spot effect.

Similarly, when the control unit controls the first chip unit 211 and the second chip unit 212 to work simultaneously, the telescopic control device 33 pushes the collimating lens device 22 to move to the middle position of the first chip and the second chip, the first chip emits the first light beam 25, the second chip emits the second light beam 26, because the distance between the two LED chips is small, the two first light beams can be substantially overlapped after being collimated by the lens unit, and then are converged by the focusing lens, and are focused on the preset surface to form the focusing spot 24, so as to present the third light spot effect.

Specifically, in this embodiment, the difference between the two LED chip units may be one or more of color, color temperature, size, shape, power, etc., so that the LED array 21 emits different first light beams.

Example 2

A light source system with adjustable light source mode, the difference between this embodiment and embodiment 1 is that the LED array is different, in this embodiment, the LED chip set located at the central portion includes two LED chip units, which are the first chip unit 211 and the second chip unit 212, and the other LED chip sets located at the edge portion only includes one LED chip unit, which is the second chip unit 212. The LED array structure is shown in fig. 5.

The first chip unit 211 has one LED chip, the first chip, and the second chip unit 212 has one LED chip, which is the second chip, and the first chip and the second chip are arranged in parallel on the central LED chip group.

When the driving mechanism drives the collimating lens to move leftward, the lens unit on the collimating lens device 22 aligns with the first chip unit 211 on all the LED chip sets, and the first chips on the first chip unit 211 jointly emit the first light beam.

When the driving mechanism drives the collimating lens device 22 to move rightward, the lens unit on the collimating lens device 22 is only aligned with the second chip unit 212 of the central LED chip set, and the second chip of the second chip unit 212 emits the first light beam.

Example 3

A light source system with adjustable light source mode, the difference between this embodiment and embodiment 1 is that the first chip unit 211 on the LED chip set is rectangular, and the second chip unit 212 is circular, both of which represent LED chips with different sizes. Due to the different sizes of the LED chips, the final light-emitting light has different spot effects, and the structure of the LED array is shown in fig. 6.

Further, the colors of the two LED chips may also be different.

Further, the color temperature of the two LED chips may also be different.

Example 4

A light source system with an adjustable light source mode, the difference between this embodiment and embodiment 1 is that a first chip unit 211 on an LED chip set includes one LED chip, which is a first chip, and a second chip unit 212 on the LED chip set includes four LED chips, which is a second chip. When the first chip emits the first light beam, the driving mechanism drives the collimating lens device 22 to move, so that the lens unit of the collimating lens device 22 is aligned with the optical center of the first chip; when the second chip unit emits the second light beam, that is, the four LED chips on the second chip unit 212 emit light at the same time, the driving mechanism drives the collimating lens device 22 to move, so that the lens unit of the collimating lens device 22 aligns with the optical center of the four LED chips after emitting light at the same time. The LED array structure is shown in fig. 7.

Example 5

Specifically, the LED chips in the first row of the LED chip set are respectively a first chip and a second chip, the LED chips in the second row are respectively a third chip and a fourth chip, and the LED chips in the third row are respectively a fifth chip and a sixth chip. The first chip, the second chip, the third chip and the fourth chip may emit light at the same time to form the first chip unit 211. The third chip, the fourth chip, the fifth chip and the sixth chip may emit light at the same time to constitute the second chip unit 212, and the control unit selectively controls the brightness of the first chip unit 211 and the second chip unit 212. Wherein, the first chip unit 211 and the second chip unit 212 share the third chip and the fourth chip. The structure of the LED chip set is shown in fig. 8 and 9.

When the control unit controls the first chip unit 211 to operate, the first chip unit 211 emits the first light beam 25 of the first type; at this time, the driving mechanism drives the collimator lens device 22 to move so that the lens unit is aligned with the optical center of the first light beam 25.

When the control unit controls the second chip unit 212 to work, the second chip unit 212 emits the second first light beam 26; at this time, the driving mechanism drives the collimator lens device 22 to move so that the lens unit is aligned with the optical center of the second first light beam 26.

As shown in fig. 8, specifically, the first chip unit 211 is a chip of four colors, i.e., a chip R, G, W, B, which generates a white light effect when the collimating lens device 22 is aligned with the optical centers of the four chips.

As shown in fig. 9, the second chip unit 212 is a W, B, W, W chip, and when the collimating lens device 22 aligns W, B, W, W, a white light effect of high color temperature is generated (because more blue light is mixed in the white light).

The B, W chip is a common LED chip for the first chip unit 211 and the second chip unit 212.

The structure of the LED chip set is shown in fig. 10 and 11.

As shown in fig. 10, specifically, the first chip unit 211 is a chip of four colors, i.e., a chip R, G, W, B, which generates a white light effect when the collimator lens device 22 is aligned with the optical centers of the four chips.

As shown in fig. 11, the second chip unit 212 is a W, W, W, W chip, which produces a white light effect when the collimating lens is aligned with W, W, W, W. Since the first chip unit 211 and the second chip unit 212 have different colors, the white light effect is different.
