Light emitting diode (LED) reflective cup

Abstract

The invention discloses a light emitting diode (LED) reflective cup which is reasonable in structural design, uniform in illumination, low in light loss, energy-saving and environment-friendly, has no halo and spot, and effectively improves illumination. The LED reflective cup comprises a base and at least one reflective cup which is arranged on the base, wherein a hollow cavity is formed on each reflective cup; the cavity along the projection direction of an LED light ray comprises a curved line reflecting surface (M2) and an oblique line reflecting surface (M1) which are connected integrally; the curved line reflecting surface (M2) is defined as a surface which is formed by rotating a curve line about a central line; and the oblique line reflecting surface (M1) is defined as the surface which is formed by rotating an oblique line about the central line.

Description

technical field [0001] The invention relates to a reflective cup, in particular to an LED reflective cup. Background technique [0002] In shopping malls, specialty stores, exhibition halls and other occasions, the traditional lighting method is to use lighting fixtures made of metal halide lamps. However, the metal halide lamp is an AC power supply, and produces an arc discharge luminescent discharge lamp in the mixed vapor of mercury and rare metal halides. The filler in the metal halide lamp contains toxic substances. Once the lamp is damaged during production or use, if it is not handled properly, the toxic substances will be directly discharged into the atmosphere, causing certain harm to the environment and human body. [0003] Although metal halide lamps have high luminous efficiency and good color rendering performance, it has been found through practice that metal halide lamps are prone to the following problems when used in shopping malls or specialty stores: 1.

AI Technical Summary

Problems solved by technology

The filler in the metal halide lamp contains toxic substances. Once the lamp is damaged during production or use, if it is not handled properly, the toxic substances will be directly discharged into the atmosphere, causing certain harm to the environment and human body.

[0003] Although metal halide lamps have high luminous efficiency and good color rendering performance, it has been found through practice that metal halide lamps are prone to the following problems when used in shopping malls or specialty stores: 1. High power, high power consumption, and high power consumption. High cost; due to the large power consumption of metal halide lamps, the cost of installation and wiring is also high, and the process is cumbersome

2. A lot of heat is generated and it is not easy to dissipate, resulting in high room temperature in the space, which makes the human body feel uncomfortable, and there are serious fire safety hazards; in shoe and clothing stores, long-term use of metal halide lamps for lighting, clothes and shoes are easy to change color

3. The service life of metal halide lamps is short. Facts have proved that the service life of metal halide lamps with better quality on the market is generally about two years, and the service life of ordinary metal halide lamps is only about seven months to one year.

4. Once there is a power outage due to an unexpected situation, if you want to restart the metal halide lamp, you must wait for the temperature of the metal halide lamp to drop to a certain level before restarting. This process will take a certain amount of time

Using LED lighting in specialty stores and other occasions, the light intensity is not high, the light loss is large, easy to produce aperture, the light concentration point is high and the illumination is uneven
