Abstract
Description
technical field
[0001] The invention belongs to the technical field of lighting equipment, and more specifically relates to an automatic focusing mechanism of a lamp and a high dome lamp including the automatic focusing mechanism. Background technique
[0002] High-ceiling light is a kind of fixed lighting fixture, which is widely used in high-ceiling lighting places such as workshops, stadiums, parking lots, large indoor gymnasiums, high-ceiling factories, supermarkets, highway toll stations, etc., as floodlight fixed lighting. Since there are many places where high dome lights are used, and the light efficiency requirements of various places are different, the light effect requirements for light fixtures are diverse; generally speaking, the area illuminated by spotlights is small and the illuminance value is high. It is suitable for places with high contrast illuminance requirements; the area illuminated by floodlight is wide and the illuminance value is low, and it is sui...
Examples
Embodiment approach
[0040] Furthermore, as an optimized implementation of the automatic focusing mechanism of the lamp provided by the present invention, the driving motor 11 has an electromagnetic brake structure. In the embodiment of this city, the driving motor 11 is equipped with a motor with an electromagnetic brake structure to prevent the output shaft 111 from rotating due to external force when the driving motor 11 stops working, which makes the focusing effect unsatisfactory.
[0041] The invention also provides a high dome light. Please also see Figure 1 to Figure 4 , the high dome light includes a focusing device 1, an electrical box 2, a lamp holder 3, a light source component 4 and a reflector 5 arranged on the lamp holder 3, and a housing portion 20 is provided under the electrical box 2, so that The focusing device 1 is arranged in the accommodating part 20, the focusing device 1 is the above-mentioned automatic focusing mechanism, the reflector cup 5 is connected with the accomm...
