Description of the Invention: [Technical Field] The present invention relates to a light source device, and more particularly to a matrix point light source device. [Previous Technology] With the development of materials such as gallium nitride (GaN), aluminum gallium nitride (AKiaN), and indium nitride (InGaN) in recent years, the mass production capability of blue and violet diodes has increased. The price of light-polar diodes has dropped rapidly, which indirectly has greatly increased the application of white-light diodes. The application of white-light diodes is quite wide. At this stage, it is mainly used in backlights and auxiliary lighting. In the current white light source device, a white light source device that combines light and light, and is mainly composed of red, blue, and green crystal grains, and then red light, Blue light and green light mix white light visible in the adult eye. The advantage of this method is that it does not need to add fluorescent powder, so it can achieve higher luminous efficiency. However, the biggest _ is the cost and control circuit. With three control wafers, the structure of the control circuit is light and complex. The luminous efficiency, wavelength and inferiority of the polar body are different, which makes it difficult to control the brightness, color rendering, color temperature, etc. _ "_Poetry-type white light source device does not meet the conversion benefit & production trend. In addition, there is a kind of white light diode composed of white raw =::= white light job - touch color balance ^ easy to control · /文点'But because of the palm of the hand, Lancome/Yuyi^difference, the same batch of white light diodes will have different chromaticity differences. Therefore, only white light diodes that meet the chroma requirements b is used, so for white light diode suppliers Nothing increases the manufacturing cost. How to provide a low-cost and simple-control white light source device is still an important research direction of the relevant personnel in this field. [Invention] In view of the above problems, the main object of the present invention is Providing a light source device, which adopts a partial color, a white color diode, and is arranged with a part of pure white light to form a moment p-type structure, thereby obtaining a white light source with good balance and white light For the body supplier, the 贱 provides a lower manufacturing cost, because the same batch of products but the different chromaticity is used.

With this device, the combination of the lion's partial blue and yellowish white light diodes reduces the overall manufacturing cost of self-color light, and because of white light. The white light diode is used in the device, so the control circuit of the white light source device is simpler in the control circuit than in the three-color diode group, and the control in brightness, color rendering, color temperature and the like is relatively simple. The features and implementations of the present invention will be described below with reference to the drawings.

The color moduli and the driving current of the body, and the control module 2 〇 can be, for example, an Application Specific Integrated Circuit (ASIC) or a Pulse Width Modulation (1323767 - PWM) controller. The diffusion plate 30 is disposed on a side opposite to the point light source module 1 , for diffusing the point light source emitted by the point source module 10 to form a surface light source. In other words, the diffusion plate 30 can control light transmittance and diffusion. The ratio of the diffusion plate % to the first circuit board 11 is more transparent to the housing 40, and the size and shape of the housing 4 can be changed according to actual needs.
