Description

Adjustable lamps

This creation is about a projection lamp, especially an adjustable lamp applied to an LED light source.

Projection lamps are often used in advertising projection, indoor and outdoor lighting, projectors or lighting equipment for automobiles and motorcycles, etc. The light sources of common projection lamps include: halogen lamps, gas discharge lamps (High Intensity Discharge Lamp, HID) and Light-emitting diode (Light-emitting diode, LED) and so on. Among them, LED has become the most common light source at this stage due to its high luminous efficiency and power saving.

However, the existing projection lamps are all-in-one designs designed for fixed light sources, which are costly and inflexible in application.

Therefore, this creation proposes an innovative projection lamp, which can provide adjustment of focal length or accommodation space according to different light sources, so as to be economically and conveniently applied to different light sources.

The present invention proposes an adjustable lamp, comprising a lens; a lens fixing mechanism sleeved on the outer edge of the lens to fix the lens; a reflective member, at least a part of which overlaps with the lens fixing mechanism, the reflective member and the lens fixing mechanism An adjustable space is formed together; and a base is coupled to the reflective member; wherein, an adjustable device is arranged between the lens fixing mechanism and the reflective member A setting is used to adjust the adjustable space for accommodating an LED light.

FIG. 1 is a schematic diagram of an embodiment of an adjustable lamp according to the present invention.

FIG. 2 is a schematic diagram of the adjustment of the lens fixing mechanism and the reflector according to the present invention.

Figure 3 shows the output lumens of the luminaire under different overlapping ranges of the reflector and the lens fixing mechanism.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an embodiment of the adjustable lamp according to the present invention. The front end of the adjustable lamp 10 is a lens 101 , and the lens fixing mechanism 102 is used to fix the outer edge of the lens 101 to make the center of the lens 101 . It is fixed at the center of the front end of the adjustable lamp 10. The reflector 104 is designed in a long cylindrical shape in this embodiment, and the interior is coated with a reflective material. The lens fixing mechanism 102 is also designed in a long cylindrical shape in this embodiment. , and at least a part of the reflector 104 is overlapped with each other, and an adjustable device 103 is arranged between the two, which is an adjustable fixing screw in this embodiment. When installing LED light sources with different lengths in the adjustable lamp 10 , the user first releases the adjustable device 103 and pulls the reflector 104 away to reduce the overlapping range with the lens fixing mechanism 102 , so that the lens fixing mechanism 102 The adjustable space formed together with the reflector 104 is elongated to an appropriate length, and after locking the adjustable device 103, a longer LED light source can be placed. Conversely, by increasing the overlapping range between the reflector 104 and the lens fixing mechanism 102, the adjustable space formed by the two can be reduced, so that a light source with a smaller size or length can be installed. The base 105 is usually made of metal, and is used to fix the other end of the reflector 104 , or is designed in different shapes according to the purpose of the adjustable light fixture 10 , so that the adjustable light fixture 10 can be installed on different apparatuses.

Please further refer to Figure 2, which shows the adjustment of the lens fixing mechanism and the reflector whole diagram. As can be seen from FIG. 2 , when the user loosens the adjustable device 103 and pulls the reflector 104 away to reduce the overlapping range with the lens fixing mechanism 102 , the length of the adjustable lamp 10 of the present invention will increase, and the length of the insertion length will be increased. Since the LED light source is relatively long, the adjustable lamp 10 of the present invention can be compatible with LED light sources of different sizes and designs.

Please refer to FIG. 3 . FIG. 3 shows the lumen condition of the lamp in different overlapping ranges of the reflector and the lens fixing mechanism. As shown in FIG. 3 , the distance D between the edge of the reflector 104 and the base 105 is 5mm, 10mm, 15mm, and 20mm respectively from top to bottom. Under the condition that the size of the built-in LED light source of the adjustable lamp 10 is fixed, by adjusting the reflector By adjusting the distance D between the edge of the element 104 and the base 105, that is, adjusting the overlapping range of the reflective element 104 and the lens fixing mechanism 102, different lumens can be output, so that the present invention can be applied to various fields.

In addition, the lens 101 can be made of various transparent materials, such as glass or high-transparency plastic. The lens fixing mechanism 102 can be designed differently according to the shape of the lens 101 , and a focal length adjusting device can also be added to further adjust the position of the lens 101 to an appropriate position according to the characteristics of the light source to enhance the beam projection effect.

The shape of the reflector 104 also needs to match the shape of the lens 101, the light source (not shown in the figure) and the lens fixing mechanism 102, so as to form an appropriate adjustable space with the lens fixing mechanism 102. The adjustable device 103 can also be composed of slide rails and corresponding Fixtures (such as screws) are composed.

The above is only the preferred embodiment of the present creation, and does not limit the present creation in any form. Although the present creation has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Personnel, without departing from the scope of the technical solution of this creation, can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above, but any content that does not depart from the technical solution of this creation, according to this creation the technical essence of Any simple modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the technical solution of the present creation.
