Description
Technical Field
The invention relates to the field of illumination, in particular to an adjustable tricolor LED lamp.
Background
Traditional three primary colors LED lamp structure, through all placing three LED lamps red, yellow and green in the focus position, modulate three LED lamps through the PWM ripples, obtain the light that needs the colour through mixing different colour light, simultaneously, the LED lamp reflects light through the parabolic mirror face, this paraboloid is with the parabolic mirror that the parabola rotates 360 degrees formation along the center pin, all install three LED lamps on the focus of parabolic mirror face center pin, the head of LED lamp 4 is towards the opening of reflection of light structure.
The three LED lamps adopting the installation mode have the following defects:
first, because the luminous intensity distribution of the LED lamp 4 is such that the light intensity is the highest when the light is perpendicular to the central axis, the larger the included angle between the light and the central axis is, the weaker the light intensity is. Therefore, the light emitted from the LED lamp 4 is the light with the strongest light intensity, which has an angle of 0-30 degrees with the central axis, but the light within the angle range cannot be irradiated on the parabolic mirror surface, so that the light is directly irradiated and wasted. The LED can irradiate the parabolic mirror, and the included angle between the light rays reflected by the parabolic mirror and the central axis is certainly larger than 60 degrees, so that the intensity of the light of the part is not high, and the irradiation distance of the light rays reflected by the parabolic mirror is not long.
Secondly, because only one LED lamp can be placed at the focus, and other LED lamps can only shift relative to the focus, the light energy cannot be fully and effectively utilized by using a plurality of LED lamps.
Thirdly, if each LED lamp is separately placed at the focus of an independent parabolic mirror, and three parabolic mirrors are used in combination, the size is large, and the illumination intensity is not sufficient.
Therefore, in order to solve the above problems, an adjustable three-primary-color LED lamp is proposed.
Disclosure of Invention
The invention provides an adjustable tricolor LED lamp aiming at the problems of focus offset, insufficient illumination intensity and the like in the tricolor LED lamp in the prior art, and the specific technical scheme is as follows:
an adjustable tricolor LED lamp is characterized in that: the LED lamp comprises three shells (1) which are sequentially arranged, wherein one end of each shell (1) is opened, the light-transmitting sheet (5) is arranged at the opening end of each shell (1), and an illumination module is arranged in each shell (1);
the illumination module comprises a reflector curved surface structure (2), an LED lamp (4) and a reflector (6);
the reflector curved surface structure (2) is installed in the shell (1), the LED lamp (4) is installed in the shell (1), and the LED lamp (4) reflects light rays by using the reflector curved surface structure (2);
the reflector curved surface structure (2) is a curved surface formed by taking a half of a parabola along the central axis of the parabola and rotating 30-180 degrees around the central axis;
the LED lamp (4) is positioned at the focus of the reflector curved surface structure (2), the top of the LED lamp (4) faces the inner surface of the corresponding reflector curved surface structure (2), the reflector (6) is installed in the shell (1), the reflector (6) is arranged adjacent to the LED lamp, the reflective inner surface of the reflector (6) faces the LED lamp (4), and the top of the LED lamp (4) faces the inner surface of the reflector curved surface structure (2);
the LED lamps (4) in the three shells (1) are respectively corresponding to a red LED lamp, a blue LED lamp and a green LED lamp.
To better implement the invention, the following steps can be further carried out: the central axis of the LED lamp (4) is positioned on the symmetrical plane of the reflector curved surface structure (2).
Further: the central axis of the LED lamp (4) is vertical to the central axis of the reflector curved surface structure (2). Due to the fact that the light rays with the strongest light ray intensity, which are emitted by the LED light and have an included angle of 0-30 degrees with the central axis, are emitted, the light rays within the angle range can effectively irradiate on the parabolic mirror surface and emit along the direction parallel to the central axis.
Further: the reflective inner surface of the reflector (6) faces the closed end of the housing.
Further: the shell (1) is of a cube structure, and the three shells (1) form a strip-shaped structure side by side.
Further: and a secondary condensing lens (7) is arranged on the LED lamp (4). The secondary condensing lens is arranged on the LED lamp, so that the light emission angle of the LED lamp is reduced through refraction, and the scattered light is reduced. So that strong light can irradiate the inner surface of the curved surface structure of the reflector.
Further: the reflector curved surface structure (2) is formed by taking a half of a parabola along the central axis of the parabola and rotating 180 degrees around the central axis. Because the emitting angle range of the adopted LED lamp is 120 degrees, the coverage range of the LED lamp is wider.
The invention has the beneficial effects that:
firstly, each LED lamp is arranged at the focus of the reflector structure in the corresponding shell, and meanwhile, the central axis of the LED lamp is perpendicular to the central axis of the reflector curved surface structure. The strongest light part emitted by the LED lamp is reflected by the corresponding curved surface structure of the reflector. The light condensation is stronger than the light condensation of the parabolic mirror structure of the traditional LED lamp, and the light scattering property is low.
Secondly, because the curved mirror surface solution structure is formed by rotating the first curve or the second curve around the central axis, the curved mirror surface structure is placed in the shell, and under the condition of the same illumination intensity, the volume of the shell provided with the curved mirror surface structure is far smaller than that of the shell provided with the parabolic mirror. Therefore, the volume of three housings which are arranged side by side and are provided with the curved surface structures of the reflectors of the invention is far smaller than that of the traditional housings provided with parabolic mirrors. The process steps and the cost can be effectively reduced.
Thirdly, the reflector can effectively refract the dissipated light of the LED lamp to the reflector curved surface structure and reflect the light out through the reflector curved surface structure. The utilization efficiency of the dissipated light is improved.
Fourthly, the secondary condensing lens is arranged on the LED lamp, so that the light emission angle of the LED lamp is reduced through refraction, and the dissipated light is reduced. So that strong light can irradiate the inner surface of the curved surface structure of the reflector.
Fifthly, each LED lamp is independently arranged in the corresponding shell, each LED lamp is arranged at the focus of the reflector structure in the corresponding shell, and meanwhile, the adopted LED lamp is opposite to the curved surface structure of the reflector, so that three beams of emitted red light, yellow light and green light are far greater than the traditional illumination intensity, and when the light is fused, the light intensity is far greater than the traditional three-primary-color LED lamp.
