Light source drive die set for digital light source processing apparatus

Abstract

The invention relates to a light source driving module group of a digital light source treatment device, which comprises a luminescence unit, a control unit, a synchronization unit and a driving unit, wherein the luminescence unit is at least equipped with a first luminescence element and a second luminescence element, the control unit outputs an adjustment signal and a sequential signal, and the control unit outputs the sequential signal according to a luminescence order of the first luminescence element and the second luminescence element. The synchronization unit is electrically connected with the control unit, receives the sequential signal and outputs a synchronization single. The driving unit is electrically connected with the control unit and the luminescence unit, receives the adjustment signal, and outputs a first driving single and a second driving single to drive the first luminescence element and the second luminescence element. The light source driving module group can avoid a rainbow effect which is produced because of color wheels, can reduce the number of elements, further reduces the making cost, and has better color saturation degree and the brightness of images compared with a prior white light source.

Description

technical field [0001] The invention relates to a light source driving module, in particular to a light source driving module of a digital light source processing device. Background technique [0002] Due to the continuous improvement of consumers' requirements for audio-visual enjoyment, projectors are gradually occupying a place in the field of displays due to their portability, portability, and large-screen effects. At the same time, due to the increasing demand for projectors, the digital light processing (Digital Light Processing, DLP) technology used by the projectors has gradually attracted the attention of the industry. [0003] Please refer to Fig. 1, in the prior art, the digital light source processing device 1 utilizes white light as its light source 11, and then first focuses the light emitted by the light source 11 on a color wheel 13 through a group of condenser lenses 12 (by red light). On the color filter composed of three colors of green and blue), the col...

Problems solved by technology

[0005] However, although the digital light source processing device 1 has the advantages of saturated colors and good details in dark parts, when the seams between the color filters on the color wheel are uneven or not close enough, and the rotation speed of the color wheel is not fast enough, etc. , also produces the absence of the so-called rainbow effect

In addition, the existing conventional technology uses white light emitting diode (Light Emitting Diode, LED) as its light source 11. Although its brightness is higher than that of traditional light sources, it still has the problem of the heat of the light source.

Because when the light source 11 is overheated, the brightness will decrease or flicker, but if the air output of the cooling fan is increased in order to reduce the heat of the light source 11, it will also increase the noise of the cooling fan and consume power.

[0006] It can be seen that the above-mentioned existing digital light source processing device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
