For example, the light source 331 may include a light source plate 333 with conductive paths for electrically connecting one or multiple LED modules in series, in parallel or in series and in parallel. Each LED module may have one or multiple LED chips, which may be covered by corresponding fluorescent layers. More than one LED chips may be integrated in one LED module for mixing a desired optical parameter, e.g. a requested color temperature, a color or other parameters.

(13) Each LED module may be integrated as a package. In addition, to change light paths of the LED module, a lens for condensing or diffusing a light of the LED module may be added to the LED module. For example, to provide a soften light, a diffusion lens may be attached above the LED chip of the LED module for diffusing light to wider directions.

(14) The driver module 331 connects to an external power source 334 and converts the external power source 334 to a driving current (invisible but should be understood for persons of ordinary skill in the art with reference to related components) supplied to the LED module 332. The driver module 331 may include a rectifier for rectifying an external AC current. Filter and PWM (pulse width modulation) circuits may be integrated in the driver module for providing a stable and controllable driving current. By controlling a duty cycle, for example, the driver module may adjust light intensity of the LED module or control multiple LED chips of one or more LED modules to mix a desired optical parameter.

(15) The main housing 31 includes a light source holder 3101 for disposing the light source 33, a driver holder 3103 for disposing the driver module 331, and a light passing holder 3102 for disposing the light passing cover 32 for a light of the LED module emitting through the light passing cover 32. Heat sink unit may be attached to the light source holder for carrying heat away from the LED module. In this example, the driver module 331 is integrated to the light source 33 but may be designed as a separate component held by the main housing, which may be easily understood by persons skilled in the art without specific drawing brevity.

(16) In this example, there is a transparent cover 34 covering the light source 34. Lens and other components may be disposed on the transparent cover 34 for redirecting light or protecting the components of the light source 33.

(17) The manual switch module 20 is attached to an external side 3105 of main housing 31.

(18) Please refer to FIG. 1. The main housing 31 has a manual switch 300 exposed on a lateral wall of the main housing 31.

(19) Please refer to FIG. 3 and FIG. 4. FIG. 3 shows an assembled view and FIG. 4 shows an exploded view. The manual switch module 20 includes a switch housing 200, a circuit board 400 and a manual switch 300. The manual switch 300 is exposed outside the main housing as shown in FIG. 1 for a user to operate. The circuit board 400 has an actuation area 401 corresponding to the manual switch 300. When the manual switch 300 is operated by the user, the actuation area 401 has an electronic status change. A controller 402 of the circuit board 400 converts the electronic status change to an operation command sent to the driver module shown in FIG. 1 for adjusting controlling of the LED module.

(20) For example, the controller 402 is a micro controller or a processor for executing stored codes for performing necessary calculation and signal conversion of the actuation area.

(21) In some embodiments, the manual switch module 20 may also include an elastic layer disposed between the manual switch and the actuation area. In FIG. 4, the elastic layer may include a conductive foam 500, but the elastic layer may also be made of other elastic structure like spring, rubber or other components.
