Description
Technical field
The present invention relates to technical field of lamps, especially relate to a kind of automatic focusing head lamp.
Background technology
Personnel such as doctor often use head lamp.Usually, this head lamp comprises headband, and the front portion of this headband is provided with lamp holder.That is, the user is worn over head with headband, can liberate both hands, utilizes the light beam inspection patient's of this head lamp ejaculation positions such as earhole easily.Its defective is: the spot position of the light beam that this head lamp is emitted is fixed, and the user must pass through moving-head, can reach best spotlight effect, comparatively inconvenience.
Summary of the invention
The purpose of this invention is to provide a kind of automatic focusing head lamp, it has the frequent moving-head of the user of need not, and can reach the characteristics of preferable spotlight effect.
The technical solution adopted in the present invention is: the automatic focusing head lamp, comprise headband, the front portion of this headband is provided with lamp holder, described lamp holder comprises stack shell, this stack shell inside is provided with light source, this light source is furnished with automatic focusing device, and wherein, this light source all is electrically connected with power supply by light source switch, this automatic focusing device by the focusing switch.
The control position of described light source switch and this focusing switch all is positioned at the outer surface top of this stack shell.
Described focusing switch is the touch-type switch.
Described power supply is positioned at the rear portion of this headband.
The present invention compares the advantage that has with prior art: need not the frequent moving-head of user, can reach preferable spotlight effect.The light source of the lamp holder of automatic focusing head lamp of the present invention is furnished with automatic focusing device.Like this, the user only need operate this focusing switch, can adjust the best focal point of the emitted light beam of this lamp holder, and then the user need not frequent moving-head, can reach best result of use.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the front view of embodiments of the invention;
Fig. 2 is the perspective exploded view of lamp holder of the present invention.
Among the figure: 10, headband; 20, lamp holder, 21, stack shell, 22, light source, 221, light source switch, 23, automatic focusing device, 231, the focusing switch, 232, motor, 233, retractor device, 234, set of lenses; 30, power supply.
The specific embodiment
Embodiment, see illustrated in figures 1 and 2: the automatic focusing head lamp, comprise headband 10, the front portion of this headband 10 is provided with lamp holder 20.Say that further this lamp holder 20 comprises stack shell 21, these stack shell 21 inside are provided with light source 22, and this light source 22 is furnished with automatic focusing device 23.Wherein, this light source 22 all is electrically connected with power supply 30 by light source switch 221, this automatic focusing device 23 by focusing switch 231.That is, closed this light source switch 221 can be lighted this light source 22, operates this focusing switch 231 and can control this automatic focusing device 23, and then regulate the position of the best focal point of these light source 22 emitted light beams.Like this, the user need not frequent moving-head, can reach best result of use.
Wherein, the lamp holder 20 with automatic focusing device can adopt present widely used automatic focusing flashlight to convert.Such as, specifically to see shown in Figure 2ly, this lamp holder 20 can be: these stack shell 21 inside are provided with motor 232, and this motor 232 connects this focusing switch 231.That is, this motor 232 is connected to this power supply 30 by this focusing switch 231.Simultaneously, these light source 22 front portions are provided with set of lenses 234, and this set of lenses 234 is connected with retractor device 233, and this retractor device 233 is connected with this motor 232.That is, this retractor device 233 is realized flexible by the rotation of this motor 232.Like this, after this focusing switch 231 is opened, these motor 232 rotations, thus this retractor device 233 starts, and the distance between this set of lenses 234 and this light source 22 is changed, and then realize the automatic focusing of this lamp holder 20.Certainly, this focusing switch 231 is provided with change-over circuit, thereby can realize main story and the counter-rotating of this motor 232.Wherein, this retractor device 233 can be taked multiple common mode, such as, take the internal and external screw thread structure that cooperatively interacts.
Optimize, the control position of this light source switch 221 and this focusing switch 231 all is positioned at the outer surface top of this stack shell 21.This control position is such as being operating key.Like this, the user stretches out one's hand and can control this light source switch 221 and this focusing switch 231, and is comparatively convenient.And this focusing switch 231 can adopt the touch-type switch.Like this, further facilitated controlling of this user.
Continue to optimize, this power supply 30 is positioned at the rear portion of this headband 10.Like this, avoided this power supply 30 to be positioned at the situation of this stack shell 21, thereby made this lamp holder 20 have smaller volume.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
