Replaceable multi-function LED lens holder

This case belongs to the field of lighting devices, especially a replaceable multi-function LED lens holder that can easily combine LED light source and lens.

In recent years, the development of LED has been rising and rising, because it has many advantages: (1) Low power consumption: Under the same lighting effect, the power consumption of LED is only one tenth of that of traditional light sources such as incandescent lamps. . (2) Long service life: LED is small in size, light in weight, shock-resistant and impact-resistant. It is less broken than traditional incandescent lamps and fluorescent lamps, and has a long service life. (3) High safety: LEDs use low voltage (DC is about 3.3 volts), traditional incandescent lamps use high voltage (110 volts AC), and the safety of LEDs is much higher than incandescent lamps, and the application range is wide. (4) Short lighting time: The LED response time is short, which is ^10-9 seconds in nanoseconds. However, the response time of traditional incandescent lamps is long, 10 to ³ seconds in milliseconds, and even longer in fluorescent lamps, so LED pairs are immediately The place where lighting is required can show its convenience. (V) High applicability: Due to the small area of the LED single crystal, it is easy to fabricate and combine into various shapes of devices, which is suitable for designing in a changing environment. (6) Environmental protection: Traditional fluorescent lamps containing mercury (mercury) are harmful poisons. LEDs have no such concerns and can be recycled without causing environmental pollution. Especially LED has experienced decades of development, and the luminous efficiency has made great progress and breakthrough. At present, the traditional incandescent lamp luminous efficiency is 12~24Lm/W, the fluorescent lamp is 50~90 Lm/W, and the sodium lamp is 90~140 Lm/ W, the maximum of LED lights has reached more than 200Lm / W, more than 2 times the traditional light source. Therefore, it has occupied a considerable position in the current life and gradually replaced various lighting equipment in daily life.

Since the LED light source has directionality and needs to be considered for optical design, most of them must be combined with a dedicated light guiding structure to suit various applications. The optical lens is an application of a light guiding structure, which is installed above the LED for guiding light, converges the angle of illumination to any angle of 5° to 160°, and adjusts the shape of the light field to enhance the intensity of the light. More even. The types of lenses are generally divided into two types: transmissive (convex lens) and catadioptric (cone or cup). The penetrating lens has a curved surface (double convex with 2 curved surfaces) when the LED light passes through the curved surface of the lens. The light will refract and condense, and the angle will also change when the distance between the lens and the LED is adjusted (the angle is inversely proportional to the distance), so that the light through the optically designed lens is very uniform, but due to lens diameter and lens mode limitation. LED light utilization is not high and the edges have obvious yellow edges. The principle of the catadioptric lens is to use the penetrating concentrating light in front, and the tapered surface can collect and reflect all the side light, and the most complete light utilization can be obtained by the overlapping of the two kinds of light (the same angle). With a uniform light effect.
