In the multi-mode light emitting region 14 of automobile tail light component 1 as shown in Figure 1, with realize big light strength ratio light-emitting mode it
Between switching.
Specifically, light emitting device 2 includes circuit board 21 and the control unit 24 that is arranged on the circuit board 21 and more
A luminescence unit 2a, 2b, 2c, 2d, 2e.Control unit 24 is electrically connected with multiple luminescence unit 2a, 2b, 2c, 2d, 2e, with control
These luminescence units 2a, 2b, 2c, 2d, 2e.It is shown in Figure 2 be provided on circuit board 21 5 luminescence unit 2a, 2b,
The case where 2c, 2d, 2e, it should be understood that more or fewer luminescence units can actually be set.
Each luminescence unit 2a, 2b, 2c, 2d, 2e include two light-emitting components 22,23 arranged next to one another.
In the present embodiment, light-emitting component 22,23 is Light-emitting diode LED.It includes two that each luminescence unit, which is shown in the figure,
The case where light-emitting component 22,23, it should be understood that can actually include more light-emitting components.
In any one luminescence unit, each light-emitting component can individually shine or with another light-emitting component
It shines together.In this way, each luminescence unit can individually shine or shine together with other luminescence units.For example,
In luminescence unit 2a, light-emitting component 22 individually shine perhaps light-emitting component 23 individually shine or light-emitting component 22 and hair
Optical element 23 shines together.
In the present embodiment, the construction of luminescence unit 2b, 2c, 2d, 2e and the construction of luminescence unit 2a are essentially identical.Cause
This, the illumination mode of the respective light-emitting component 22 of luminescence unit 2b, 2c, 2d, 2e and light-emitting component 23 is also with luminescence unit 2a's
The illumination mode of light-emitting component 22,23 is essentially identical.
Fig. 2 shows be situation that luminescence unit 2a, 2b, 2c, 2d, 2e are arranged in along straight line on circuit board 21, it is practical
These upper luminescence units can also arrange along curve.In addition, Fig. 2 shows be the edge multiple luminescence unit 2a, 2b, 2c, 2d, 2e
Plane (that is, plane where flat circuit board 21) arrangement the case where, actually these luminescence units can also be along song
Face arrangement.
Next it is described by luminescence unit of the example to the present embodiment of luminescence unit 2a.It should be understood that needle
Other luminescence units are also applied for the description of luminescence unit 2a.
Fig. 3 A, Fig. 3 B, Fig. 3 C and Fig. 3 D are the arrangement mode of the luminescence unit of embodiment according to the present utility model respectively
Schematic diagram.As shown in Fig. 3 A to Fig. 3 D, in luminescence unit 2a, it is provided with light-emitting component 22 and light-emitting component adjacent to each other
23.Light-emitting component 22 can as shown in Figure 3A and Figure 3B as in a first from left arranges rightly in the form of, or such as Fig. 3 C and figure
As shown in 3D in the form of arranging one on the other.Alternatively, it is also possible to be arranged as shown in Figure 2 along inclined direction
Column.The type of light-emitting component 22 and light-emitting component 23 can be mutually the same or different.For example, light-emitting component 22 and light-emitting component
The characteristic size (such as outer diameter or side length) of 23 shape can be about 1mm to 2mm, and light-emitting component 22 and light-emitting component
The distance between 23 D can be about 0.5mm.Thus the light that light-emitting component issues is realized in the case where can satisfy assembly
Peak use rate.
The important feature of the present embodiment is that the color for the light that light-emitting component 22 and light-emitting component 23 are respectively issued is each other
It is identical, but luminous intensity is different from each other.For example, light-emitting component 22 and light-emitting component 23 issue the mutually the same feux rouges of wavelength, but send out
The luminous intensity of optical element 22 is 10 times of the luminous intensity of light-emitting component 23 or more or even 20 times or more.More specifically, light-emitting component
22 luminous intensity is 20 lumens (1m), and the luminous intensity of light-emitting component 23 is 1 lumen (1m), that is to say, that 22 He of light-emitting component
The light strength ratio of light-emitting component 23 is 20.In this case, if carrying out current control using PWM for same light-emitting component
To change its brightness size, this is difficult to realize.
Under the light-emitting mode of brake indicator lamp, the light-emitting component 22 of each luminescence unit 2a, 2b, 2c, 2d, 2e are sent out
Light, and the second light-emitting component 23 does not shine.Under the light-emitting mode of taillight, each luminescence unit 2a, 2b, 2c, 2d, 2e's
Light-emitting component 23 all shines, and light-emitting component 22 does not shine.
In this way, the observer outside automobile tail light component 1, the luminous intensity of multi-mode light emitting region 14 can be big
Switch between the light-emitting mode of light strength ratio.Correspondingly, other than luminous intensity changes, multi-mode light emitting region 14 is sent out
Color, pattern of light out etc. hardly happen variation.It is thus achieved that the technical purpose of the utility model.
It, can be with although describing light-emitting component 22 and light-emitting component 23 not situation luminous simultaneously in the above-described embodiments
It is contemplated that light-emitting component 22 and light-emitting component 23 can also shine simultaneously if necessary, so that multi-mode light emitting region 14
Luminous intensity maximizes.
Although hereinbefore light emitting device according to the present utility model is illustrated using automobile tail light component as example,
It should be apparent that light emitting device according to the present utility model can also show before being applied to after simple modification
Wide lamp, lamp daytime running etc. need to switch the occasion of luminous intensity.
It is envisioned that above-mentioned light emitting device can also include light guide, reflecting part etc., to luminescence unit
The light of sending is guided or is adjusted.
It is carried out above by referring to technical purpose, technical solution and technical effect of the specific embodiment to the utility model
Detailed description.It should be understood that above-described embodiment is merely exemplary, rather than it is restrictive.In the utility model
Spirit and principle within, any modification, equivalent substitution, improvement and etc. that those skilled in the art makes are comprised in this reality
Within novel protection scope.
