Detailed Description
For further explanation of the principles and construction of the present invention, reference will now be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings.
The lamp structure with adjustable lighting effect in this embodiment is shown in fig. 1, and includes a base, a reflective cup, a light source base, and a plurality of LED light sources mounted on the light source base.
As shown in fig. 2, the reflector cup 2 includes a circular top plate 21, a peripheral edge of the circular top plate 21 extends downward to form a sidewall 22, and the sidewall 22 is a tapered cylindrical structure with a diameter gradually increasing downward. The bottom of the side wall 22 extends radially outwards to form a main reflecting part 23, and the outer edge of the main reflecting part 23 extends downwards to form a skirt part 24; an internally threaded ring 26 is formed at the bent portion of the side wall 22 adjacent to the primary light reflecting portion 23, and the internally threaded ring 26 has an internal thread structure. As can also be seen from the figure, the side wall 22 is further provided with a plurality of light-transmitting grids 25, specifically 8 light-transmitting grids 25 are uniformly arranged on the side wall 22 along the circumferential direction, and each light-transmitting grid 25 is a long through hole along the extending direction of the side wall 22. Obviously, the light-transmitting compartment 25 is located above the primary light-reflecting portion 23. The outer surfaces of the reflecting cups 2 are reflecting surfaces with good reflectivity, wherein the upper surface of the main reflecting part 23 is a main reflecting surface, and the outer surface of the side wall 22 is a secondary reflecting surface. In this embodiment, an included angle θ between the primary reflecting surface and the axis of the reflector cup 2 is smaller than 90 degrees, that is, an included angle θ between the primary reflecting portion 23 and the axis of the reflector cup 2 is smaller than 90 degrees. The included angle theta between the main reflecting surface and the axis of the reflecting cup 2 can influence the light condensation state of the light irradiated by the lamp, so that the size of theta can be adjusted according to the requirement of practical application.
As shown in fig. 2, base 1 and light source base 3 are a one-piece structure in this embodiment. The base 1 comprises an annular bottom plate 11, the inner edge of the bottom plate 11 extends upwards to form a light source seat 3, as can be seen from the figure, the light source seat 3 is also of a conical cylindrical structure with a downward gradually increasing diameter like the side wall 22 of the light reflecting cup 2, and the upper part of the light source seat 3 is of a flat sealing structure. An external thread ring 4 is arranged on the outer side of the bottom of the light source seat 3, and the external thread ring is used as a reflection cup installation part and has an external thread structure. As shown in fig. 3, the external thread structure of the external thread ring 4 is matched with the internal thread structure of the internal thread ring 26 on the reflector cup 2.
In addition, a positioning part 12 is formed by extending upwards and downwards near the outer edge of the bottom plate 11, and the bottom plate 11 outside the positioning part 12 is set as a mounting part 111; the bottom plate 11 is provided with a wire passing hole 13.
The LED light source 5 is fixed on the light source seat 3, and the outer side of the light source seat 3 corresponding to the position of each light-transmitting grid 25 is fixedly attached with one LED light source 5.
The lamp with adjustable lighting effect of the present embodiment further includes a housing 6, the housing 6 is a cylindrical structure, and a transparent member 7 is installed at an upper opening of the housing 6. An annular catching groove is formed at the lower portion of the inner side of the housing 6, and the catching groove can catch the mounting portion 111 of the floor 11 therein, thereby fixing the base 1 in the housing 6. The lower part of the shell 6 is in a closed shape, and finally a wire passing hole for wiring is formed.
When the lamp works, the reflecting cup 2 is indirectly fixed with the light source seat 3 in a threaded connection mode, and when the number of the matched buttons of the threads is adjusted, the distance between the LED light source 5 and the main reflecting surface and the angle between the LED light source 5 and the main reflecting surface can be adjusted, so that the lighting mode can be switched between light condensation and floodlight. Meanwhile, when the number of the matched threads is adjusted, the difference of illumination brightness (illumination intensity) can be influenced, and the illumination efficiency can be adjusted by adjusting the size of the light-transmitting grids 25 of the LED light source 5 exposed out of the reflection cup 2.
Certainly, in order to ensure the normal operation of the lamp, the overall size of the light source base 3 provided with the LED light source 5 and the LED light source 5 should be smaller than the size of the reflective cup 2 at the corresponding position, so that when the reflective cup 2 is rotated, the side wall 22 of the reflective cup 2 cannot be scratched to touch the LED light source 5 to cause damage.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, but rather is intended to cover all equivalent structural changes made by the use of the specification and drawings.
