Problems solved by technology

[0004] Since the circuit board and other components of the LED light source need to be placed in the position of the light-emitting part of the street lamp, when external reasons or environmental factors cause a short circuit on the circuit board and require maintenance, it is necessary to open the light-emitting position of the street lamp for maintenance, which makes maintenance inconvenient. Rising maintenance costs

[0030] The laser light emitting device in the present invention generally consists of three parts: a light source control part, a light transmission part and a terminal part, wherein the light source control part and the terminal part are set separately. figure 1 A first embodiment in which the laser light emitting device of the present invention is applied to the traffic light system 100 is shown.

[0031] exist figure 1 In the illustrated embodiment, the light source control unit 100a is a light source control unit built in a non-harsh environment (such as indoors), and it can also be placed at the bottom of the traffic lights or set on the ground. For the selection of the construction site, those skilled in the art can select a suitable area according to factors such as the region or the specific requirements of the system using the laser light emitting device, which will not be repeated in the present invention. Compared with the harsh outdoor environment, the indoor envi...

[0066] Such as Image 6 As shown, the wavelength selection part 107 is a wavelength selection dial, and the wavelength selection area therein is a fan-shaped area, and the angle corresponding to each fan-shaped area can be adjusted according to the light-emitting time of each corresponding color. exist Image 6 In the illustration, the wavelength selection unit 107 includes four wavelength selection regions as an example for description.

[0067] exist Image 6 Among them, the wavelength selection part 107 includes a green wavelength selection region a, two yellow wavelength selection regions c and a red wavelength selection region b, wherein the yellow wavelength selection region c is sandwiched between the green wavelength selection region a and the red wavelength selection region between light wavelength selective regions b. By adjusting the rotational speed of the wavelength selection turntable and the angle corresponding to the wavelength selection area, the required l...

[0097] Figure 13 A second embodiment in which the laser light emitting device of the present invention is applied to a traffic light system 200 is shown.

[0098] The same parts in the second embodiment and the first embodiment are described with the same reference numerals, and the detailed description of the same parts is omitted, and only the difference between the second embodiment and the first embodiment will be described below.

[0099] see Figure 13 , the traffic light system 200 includes a light source module 201 , a wavelength selection unit 207 , an optical transmission unit 108 and a terminal unit 202 . and figure 1 By comparison, it can be seen that one light source module is used to control a single traffic light in the first embodiment, while two light source modules 201 are used in the second embodiment, and the two light source modules 201 use the same wavelength selection part 207, and respectively control two terminal parts (traffic lights) of the inter...

Abstract

The invention aims to provide a laser emitting device. The device comprises at least one light source module used for emitting first light, a wavelength selection unit used for selecting wavelength ofthe first light passing through the wavelength selection unit and emitting second light, at least one terminal part and at least one light transmission part, wherein each terminal part comprises a light guide plate used for receiving the second light and emitting the second light after carrying out light uniformizing treatment; the light transmission parts are used for transmitting the second light to the terminal parts. The laser light emitting device can be applicable to signal indication and illumination of some occasions where a circuit cannot be introduced.

Description

technical field [0001] The invention relates to a laser light emitting device. Background technique [0002] At present, as an energy-saving and environment-friendly light source, light-emitting diode (LED) has generally replaced traditional light sources, and is widely used in various indoor and outdoor places, such as: home indoor lighting, shopping mall decorative lighting, stage lighting, outdoor street lights , Square lighting, advertising display boards, decorative lighting on building exterior walls, traffic lights, etc. But there are many problems when using LED light source outdoors. For example, since the outdoor environment is much harsher than the indoor environment, this harsh environment will seriously reduce the service life of the LED light source and bring great inconvenience to devices and places using the LED light source. For example, if the traffic lights using LED light sources break down irregularly, it may seriously affect the traffic order. This s...
