Description
Technical field
The present invention relates to a kind of light fixture, more particularly, relate to a kind of portable floodlight-condensing lamp.
Background technology
The all poly-floodlight function of existing LED flashlight, illumination functions is single, and need torch that the nearby illumination of illumination broadness arranged when walking night, but when wanting to see guideboard at a distance or maintenance, need the high light of assembling.And the reflector of existing poly-floodlight to be form or reflector frosted by out of focus form poly-floodlight, the black hole will inevitably appear in the poly-floodlight that the form by out of focus forms, and the black hole occurs in the zone that needs torch for illumination, has just lost the function of use of torch; The poly-floodlight that form by the reflector frosted forms then can reduce the illumination effect of light fixture greatly.
Summary of the invention
The objective of the invention is to solve a light source and realize the optically focused of poly-floodlight function and two reflector formation when only using a light source and the problem that floodlight interferes with each other.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of portable floodlight-condensing lamp, comprise lamp holder, housing and be used for the battery of power supply being provided and being arranged on Transparent Parts on the lamp holder to illuminator; It is characterized in that, on the Transparent Parts and be positioned at illuminator directly over locate to be provided with convex lens, be provided with a curved surface light-reflecting device and at the lamp holder inwall and can make illuminator disposed thereon rotation respectively to convex lens and the luminous rotating mechanism of curved surface light-reflecting device.
In Transparent Parts of the present invention, be positioned at illuminator directly over locate to be provided with convex lens, when illuminator forward convex lens were luminous, light converged the back through convex lens and penetrates, and forms optically focused.
Curved surface light-reflecting device of the present invention is arranged on the lamp holder rear side end, keeps certain biased declinate degree of side with illuminator; Luminous when illuminator forward curved surface light-reflecting device, light sees through Transparent Parts and forms floodlight after its reflection.
There is certain relative angle in illuminator of the present invention, curved surface light-reflecting device, convex lens three's position, and this angle can be that to be subjected to the light mid point with the front of convex lens be that the angle that initial point was become is 105 ° of angles with the luminous mid point of illuminator to curved surface light-reflecting device.Under this angle, can in the process of curved surface light-reflecting device luminous intensity distribution, avoid and the interfering with each other of lens.
Rotating mechanism of the present invention is a cross bar, and its two ends hang on the sidewall of lamp holder, and can rotate relatively, and an end or the two ends of rotating mechanism are provided with knob, make things convenient for the rotation of rotating mechanism; Illuminator is arranged on the described cross bar, and luminous to lens and curved surface light-reflecting device respectively with the cross bar rotation.
The present invention uses a rotating mechanism that is provided with illuminator, controls the light emission direction of illuminator by the direction of rotation of control rotating mechanism, and luminous to convex lens and curved surface light-reflecting device, planoconvex lens converges and curved surface light-reflecting device reflection back forms optically focused and floodlight.Only just can realize gathering the floodlight function, and optically focused and floodlight all are independently and indefectible with a light source; Solved and existingly formed poly-floodlight by the out of focus form and can occur the black hole in the field of illumination and form the problem that poly-floodlight can reduce the illumination effect of light fixture greatly by the reflector frosted.The present invention realizes the function of poly-floodlight with led light source, and floodlight is had certain angle requirement, does not need the so big lighting angle of light source self; Have advantages such as light efficiency height, energy consumption is low, volume is little, service time is long.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is the structural representation of the first embodiment of the present invention;
The specific embodiment
Fig. 2 shows preferred embodiment of the present invention, and described portable floodlight-condensing lamp comprises lamp holder 110, place illuminator 150, curved surface light-reflecting device 130, rotating mechanism 160 in the lamp holder, place that Transparent Parts 120, the Transparent Parts 120 of lamp holder top are provided with directly over convex lens 140 and position and the illuminator 150, the lamp holder outside is connected with a knob 161, housing 100 with rotating mechanism and places the power supplys 170 of powering to illuminator 150 in the housing 100.
Described illuminator 150 is light emitting diode in this embodiment.
The described convex lens 140 that are located on the Transparent Parts 120, be positioned at illuminator 150 directly over, luminous when illuminator 150 forward convex lens 140, form optically focused by convex lens.
Described curved surface light-reflecting device 130 is arranged on the lamp holder rear side end, and keeps certain biased declinate degree of side with illuminator 150; Luminous when illuminator 150 forward curved surface light-reflecting devices 130, light sees through Transparent Parts 120 and forms floodlight after its emission.
In the present embodiment, a more excellent implementation is proposed for illuminator 150, curved surface light-reflecting device 130, convex lens 140 threes' relative position: described convex lens 140 be positioned at illuminator 150 directly over, illuminator 150 can be just luminous towards convex lens 140; When illuminator 150 just towards curved surface light-reflecting device 130 when luminous, curved surface light-reflecting device is in line with the luminous mid point of illuminator by the mid point of light should become 15 ° of angles with horizontal line; Say that further it is that the angle that initial point was become is 105 ° of angles with illuminator 150 luminous mid points that curved surface light-reflecting device 130 is subjected to the light mid point with the front of convex lens 140, the three just can avoid reflector and convex lens to interfere mutually in the process of luminous intensity distribution at this relative position.
Described rotating mechanism 160 is a cross bar, and its two ends are horizontal to be hung on the sidewall of lamp holder 110, and can rotate relatively, is provided with knob 161 at an end or the two ends of described rotating mechanism, makes things convenient for the rotation of rotating mechanism 160; Illuminator 150 is located on the cross bar, and rotates with cross bar, and is luminous to convex lens 120 and curved surface light-reflecting device 130 by rotating horizontal pole control illuminator 150; Can form optically focused, floodlight respectively, only just can realize gathering the floodlight function, and optically focused and floodlight all be independently and indefectible, and the optically focused and the floodlight of two reflector formation when only using a light source can not interfere with each other with a light source.
The present invention is by providing a kind of portable floodlight-condensing lamp, and the out of focus form of passing through that the light fixture that uses relatively at present occurs forms poly-floodlight, can the black hole occur in the field of illumination; And form poly-floodlight by the reflector frosted, can greatly reduce the problems such as illumination effect of light fixture. The present invention realizes the function of poly-floodlight with led light source, and satisfies floodlight is had certain angle requirement, does not need the requirement of the so big lighting angle of light source self; Have the advantages such as light efficiency height, energy consumption is low, volume is little, service time is long.
