Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1-3, fig. 7 and 8, an optical element matching structure of a linear array reading lamp mainly includes a plurality of LED assemblies 11 distributed in a linear array, a plurality of inner lenses 2 distributed in a linear array, and a plurality of outer lampshade light-transmitting units 31 distributed in a linear array. The number of the LED groups 11 is at least three, and the number of the inner lenses 2 is the same as that of the LED groups 11, so that after each LED group 11 is turned on, light distribution can be performed by the corresponding inner lens 2. Therefore, the light emitting surface of each LED assembly 11 corresponds to the light entering surface of each inner lens 2, i.e., the light emitted from each LED assembly 11 is incident on the corresponding inner lens 2.

The number of the outer lamp cover light-transmitting units 31 is either the same as the number of the inner lenses 2 or one less than the number of the inner lenses 2. Therefore, referring to fig. 7, when the number of the outer-lampshade light-transmitting units 31 is the same as the number of the inner lenses 2, the light-emitting surface of each inner lens 2 corresponds to the light-entering surface of each outer-lampshade light-transmitting unit 31, i.e. the light beams emitted after being distributed by each inner lens 2 are emitted to the corresponding outer-lampshade light-transmitting units 31. Referring to fig. 8, when the number of the outer-lampshade light-transmitting units 31 is one less than the number of the inner lenses 2, the light-emitting surface of each two adjacent inner lenses 2 respectively corresponds to the light-entering surface of the adjacent outer-lampshade light-transmitting unit 31, that is, each outer-lampshade light-transmitting unit 31 respectively corresponds to two inner lenses 2, and the light emitted after light distribution of each two adjacent inner lenses 2 respectively emits to one corresponding outer-lampshade light-transmitting unit 31. In any of the above two modes, the vehicle occupant can adaptively select the best one of the lamp cover light-transmitting units 31 to light up, so that the vehicle occupant can be ensured to be in the best irradiation position of the reading lamp, and the best use experience of the reading lamp can be obtained.

Referring to fig. 2 and fig. 3, an end surface of the inner lens 2 near one end of the LED assembly 11 is recessed to form a light inlet channel 21, and a bottom surface of the light inlet channel 21 is a light inlet surface of the inner lens 2, so that light can enter the inner lens 2 as much as possible, and brightness of the reading lamp is improved. The light inlet surface of the inner lens 2 is of a cambered surface structure or a conical surface structure protruding towards the LED assembly 11, so that light can be collimated, and better light distribution is realized.

Further, the LED assembly 11 can be arranged to protrude into the light entry channel 21, thereby further allowing more light to enter the inner lens 2.

Referring to fig. 1 and fig. 2, in the present embodiment, only one outer lamp cover 3 may be configured, and the outer lamp cover light-transmitting units 31 are distributed on the outer lamp cover 3 in a linear array, which is simple and reliable, easy to assemble, and low in cost.

In this embodiment, each outer lampshade light transmitting unit 31 may be individually configured with one outer lampshade 3, each outer lampshade light transmitting unit 31 is respectively disposed on the corresponding outer lampshade 3, and each outer lampshade 3 is distributed in a linear array.

In addition, the outer lampshade light transmission unit 31 and other parts of the outer lampshade 3 can be integrally formed by adopting a two-color injection molding process. The diffuse reflection patterns on the outer lampshade light transmission unit 31 can be designed arbitrarily according to actual requirements.

Similarly, in this embodiment, only one PCBA1 may be configured, and the LED assemblies 11 are distributed on the PCBA1 in a linear array, which is simple and reliable, easy to assemble, and low in cost.

In this embodiment, each of the LED assemblies 11 may be individually configured with one PCBA1, each of the LED assemblies 11 is disposed on the corresponding PCBA1, and each of the PCBAs 1 is distributed in a linear array.

Referring to fig. 4-6, the power of each LED assembly 11 is 0.5W-3W, which not only ensures the brightness of the reading lamp and provides sufficient lighting conditions for the user, but also prevents the excessive brightness from affecting the sight of the driver and ensures the driving safety. The LED assembly 11 may have various combinations. The LED assembly 11 may be composed of one LED bead or a plurality of LED beads.

The LED combinations 11 are all at least one warm color LED and cold color LEDs with the same number as the warm color LEDs, and can obtain the illumination effects of warm color light, cold color light and natural light according to the use requirements of the passengers and the passengers. Specifically, the color temperature of a normal warm color LED is about 2700K-3000K, and the color temperature of a cold color LED is about 5500K-6500K, so that when only the warm color LED is lighted, the color temperature of the emergent light of the LED combination 11 is about 2700K-3000K, and belongs to warm color light; when only the cold color LED is lighted, the color temperature of the emergent light of the LED combination 11 is about 5500K-6500K, and belongs to cold color light; when the warm color LED and the cold color LED are simultaneously lighted, the color temperature of emergent light of the LED combination 11 is about 4000K, and the LED combination belongs to natural light.

The LED assemblies 11 are all at least one RGBLED, that is, the LED lamp beads of the LED assemblies 11 are all RGBLED. The reading lamp not only can obtain the lighting effects of warm color light, cold color light and natural light like the combination of half warm color LED and half cold color LED, but also can emit light with various colors, so that the reading lamp can be used as an atmosphere lamp.

The LED assembly 11 is at least one single color LED, which is the least expensive and the control circuitry of the PCBA1 is the simplest.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
