Abstract: The present invention discloses variable focus spotlight with spin type focusing structure, the variable focus spotlight includes a shell, a driving ring and a focusing module. With the implementation of the present invention, the focusing module slides toward or away from the light source in the shell by rotating a driving ring which pulls the connecting rods penetrating position spiral slits on the shell, so that the variable focus spotlight with spin type focusing structure can easily output a broad beam, a collimated beam, or a beam ranging between the broad beam and the collimated beam according to user's needs to widely promote applications of the variable focus spotlight.

Abstract: A zoom spotlight has a reflector, a light source, a fixed lens, and a movable lens. The movable lens of the zoom spotlight can be moved and thereby adjusted in position relative to the fixed lens so that the zoom spotlight can output a broad beam, a collimated beam, or a beam ranging between the broad beam and the collimated beam, according to the user's needs.

Abstract: A lamp structure of an adaptive streetlight includes a housing, a plurality of light sources, and a surface-structured diffusion plate. The surface-structured diffusion plate enables the lamp structure to provide a light pattern conforming to the curvature of the road to be illuminated or other sites of application, thus reducing not only the number of lamps or streetlights required for a curvy road section, but also the associated installation cost and power consumption. The lamp structure can enhance road users' safety and the safety of our daily lives by increasing the illuminance on a curvy road and other sites of application that have special requirements.

Abstract: The present invention provides a light-emitting module, which comprises a light-emitting device, a light-guiding member, and an external light-guiding member. The light-emitting device emits light. The light-guiding member is disposed on the light-emitting path of the light-emitting module; the external light-guiding member is disposed on the light-emitting path of the light-emitting member. The light-guiding member distributes the light over the light-incidence surface of the external light-guiding member uniformly. After the external light-guiding member, the light is modified to axially symmetric light. Besides, the light-emitting device is disposed in a reflection ring, and a diffuser is disposed on the light-emitting path of the light-emitting device. When a minority of the light-emitting device fail, although the overall energy of the light source is reduced, the influence on the light emission of the light-emitting module is not significant.

Abstract: A LED plant light includes an optical reflector having at least one incident hole at the top and at least one emitting hole at the bottom thereof, a LED illuminant placed at the end of the incident hole, and a diffuser assembled to the bottom of the optical reflector and corresponding to the emitting hole for transmitting the light beam. The optical reflector is located between the LED illuminant and the diffuser. The optical reflector collects as much light as possible from the LED illuminant at first, and then the light are mixing on the diffuser to further transmit to the plant; if an illuminative range cannot completely cover a planting area, a user just adjusts the location of the diffuser in order to change the angle of the emitting light and to enlarge the illuminative range for giving the plant one uniform illumination.
