Problems solved by technology

However, the luminous characteristics of existing lighting fixtures are fixed when they leave the factory, and can only be applied to a single environment, and their ability to adapt to the environment is poor
If the existing lighting fixtures are to be used in different regions, it is necessary to design corresponding lighting fixtures with different luminous characteristics, which will greatly increase the production cost
Moreover, even if lighting fixtures with specific optical parameters are designed for a specific region, they cannot be applied to different environments due to changing climates.

Embodiment Construction

[0044] Figure 1A It is a schematic diagram of a light source module in a first state according to an embodiment of the present invention. Figure 1B for Figure 1A A schematic diagram of the light source module in the second state.

[0045] Please refer to Figure 1A as well as Figure 1B , in this embodiment, the light source module 100a includes a light emitting element 110 , a variable focus lens 120 , a circuit board 130 , a controller 140 and an environmental parameter sensor 150 . In the following paragraphs, the above-mentioned components and the arrangement relationship between the components will be described in detail.

[0046] The light emitting element 110 generally refers to an optical element having a light emitting function. The light emitting element 110 is used to emit light beam L. For example, the type of light-emitting element 110 may be a semiconductor light-emitting element, such as a light-emitting diode (Light Emitting Diode, LED), an organic light-...

Abstract

A light source module including a light emitting element, a tunable-focal length lens and a controller is provided. The light emitting element is configured to emit a light beam. The tunable-focal length lens is disposed on a transmission path of the light beam. The controller is coupled to the tunable-focal length lens, and adjusts a characteristic of the tunable-focal length lens in a first status and a second status.

Description

technical field [0001] The present invention relates to a light source module, in particular to a light source module with a variable focus lens (Tunable-focalLength Lens). Background technique [0002] Most of the existing lighting fixtures have their luminous characteristics fixed when they leave the factory. However, in different climatic environments, the optical behavior of the light beam will also be correspondingly different. Due to the different climatic environments in different countries, each country has its own laws and regulations to regulate lighting fixtures. [0003] For example, in a sunny day or an environment with low fog, the concentration of water vapor in the environment is low, and it is easier for the light beam to travel in a straight forward manner in the environment medium, and at this time, a light beam with a higher color temperature is more suitable. On the other hand, in rainy or foggy environments, the concentration of water vapor in the env...
