Abstract
The utility model relates to a LED (light emitting diode) flashlight with a replaceable light source, and belongs to the technical of LED flashlights. The LED flashlight comprises a casing, a light source, a dry cell and a connecting piece, wherein the light source, the dry cell and the connecting piece are arranged in the casing. The LED flashlight is characterized in that a replaceable COB (chip on board) light source is adopted as the flashlight light source, an aluminum base plate is adopted as a light source seat of the light source, the light source seat is provided with a LED, one side of the light source seat is provided with a light source positive electrode, the other side of the light source seat is provided with a light source negative electrode, the light source negative electrode and a metal strip are connected by a movable metal slide block, the metal slide block is provided with a plastic control switch, the front end of the light source is provided with a condensing Fresnel lens, the back side of the light source is provided with a heat radiating plate, the upper side and the lower side of the heat radiating plate, corresponding to the light source negative electrode and the light source positive electrode, are respectively provided with a concave groove, and the light source is inserted in the concave groove of the heat radiating plate. The corresponding condensing Fresnel lens is used as a condensing lens. When the light source is replaced, the COB light source is changed, and the internal structure of the flashlight is changed, so a user can independently replace the light source.
Description
Technical field
The utility model belongs to LED flashlight technical field, is specifically related to a kind of replaceable LED flashlight of new type light source based on COB technology LED bulb.
Background technology
At present, the LED flashlight mostly is led chip is packaged into the LED device, then the LED device is assembled the Lights section of making the LED flashlight, the problem that such flashlight exists has: if single damage of 1 LED will cause the flashlight non-uniform light, even cause whole light source to damage, the flashlight life-span reduces; 2 complex procedures cause cost to rise; Although 3 in theory the LED life-span very long, certain useful life is also arranged, and the parts such as shell will belong to permanent usability, so if the lamp pearl is replaceable, then will reduce cost of investment in the future.
Summary of the invention
Not replaceable in order to overcome the LED lamp bulb of electric torch, the deficiency that life-span is shorter, the utility model provide a kind of light source replaceable LED flashlight, and not only operation is simple but also clear in structure for this flashlight, for the user, can detect voluntarily flashlight, self-changeable parts etc. according to specification fully.
The technical scheme that its technical problem that solves the utility model adopts is: the replaceable LED flashlight of a kind of light source, comprise housing and be located at housing interior light source, dry cell and connector, feature is that the torch light source adopts removable COB light source, described light source is take aluminium base as light source base, light source base is provided with light emitting diode, light source base one side is provided with the light source positive pole, and opposite side is provided with the light source negative pole; Be connected by metal slide block movably between light source negative pole and the metal tape, the metal slide block is provided with the plastics gauge tap; Described light source front end is provided with light-focusing Fresnel lens, and the light source back is provided with heat sink, and heat sink is provided with respectively groove in corresponding light source both positive and negative polarity place, both sides up and down, and light source is plugged in the groove of heat sink.Described light source positive pole connects the dry cell positive pole, and metal tape connects dry battery cathode, and metal tape connects the light source negative pole by the metal slide block, and electric torch is bright, otherwise, disconnecting between metal tape and the metal slide block, electric torch goes out.
The beneficial effects of the utility model are: according to the characteristics of torch light source needs optically focused and the wide-angle luminescence characteristic property run counter to of COB light source, we have designed corresponding light-focusing Fresnel lens as collector lens.Changing on the light source, we change the design of COB light source, and the electric torch internal structure design, but allow user's self-changeable light source.When the LED flashlight breaks down because of light source, do not need to throw away, and the Lights section inside only need to changing, other still get final product.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. housing, 2. Fresnel Lenses, 3. light emitting diode, 4. light source negative pole, 5. metal slide block, 6. gauge tap, 7. metal tape, 8. spring, 9. dry battery cathode, 10. dry cell is anodal, 11. dry cells, 12. heat sinks, 13. light sources are anodal, 14. light sources.
The specific embodiment
Further the utility model is illustrated below in conjunction with the drawings and specific embodiments;
Embodiment: as shown in Figure 1, the replaceable LED flashlight of a kind of light source, comprise housing (1) and be located at housing interior light source (14), dry cell (11) and connector, feature is that torch light source (14) adopts removable COB light source, described light source (14) is take aluminium base as light source base, light source base is provided with light emitting diode (3), and light source base one side is provided with light source positive pole (13), and opposite side is provided with light source negative pole (4); Be connected by metal slide block (5) movably between light source negative pole (4) and the metal tape (7), metal slide block (5) is provided with plastics gauge tap (6); Described light source (14) front end is provided with light-focusing Fresnel lens (2), light source (14) back is provided with heat sink (12), heat sink (12) up and down both sides corresponding light source both positive and negative polarity place is provided with respectively groove, and light source (14) is plugged in the groove of heat sink (12).Described light source anodal (13) connects dry cell positive pole (10), metal tape (7) connects dry battery cathode (9), metal tape (7) connects the light source negative pole by metal slide block (5), electric torch is bright, otherwise, disconnect between metal tape (7) and the metal slide block (5), electric torch goes out.The utility model separates light source (14) part, forms an independent individuality, is convenient to the user and changes light source (14), only the light source both positive and negative polarity need to be aimed at two grooves of heat sink (12), note both positive and negative polarity, insert and get final product, very safe and convenient.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, the apparent variation of being extended out thus or change still are among the protection domain of the present utility model.
