PAR lamp

Abstract

The invention relates to a PAR lamp. The PAR lamp comprises a lamp cap, a shell connected with the lamp cap, a driving power supply positioned in the shell, a metal cup positioned in the shell, an LED lamp panel positioned at the bottom of the metal cup, a lens positioned on the LED lamp panel, and a lamp cover; the lens includes multiple single lenses; reflecting surfaces of the single lenses are provided with netty structures; surfaces of the netty structures are arc surfaces; projections are uniformly distributed on the inner surface of the lamp cover; the contacted surfaces of the projections with the lamp cover are hexagonal; and the surfaces are arc surfaces. The PAR lamp is more uniform in light spots, better in color compatibility and higher in color purity, and thoroughly eliminates yellow spots; and on the other hand, the projections are uniformly distributed on the inner surface of the lamp cover, so that internal elements cannot be directly seen from the external of the PAR lamp, and the overall beauty of the PAR lamp is improved.

Description

technical field [0001] The invention relates to a lamp, in particular to a PAR lamp. Background technique [0002] As a new generation of light source, LED has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy dimming, concentrated beam, easy maintenance, etc., and can be widely used in various indications , display, decoration, backlight, general lighting and other fields. [0003] 1. In the traditional PAR lamp, the reflective surface of the lens is flat, the light emitted by the LED lamp bead is reflected neatly, and it is easy to image, and the yellow spot of the LED lamp bead is easy to appear. On the other hand, the lampshade is usually made of transparent or translucent glass lampshade , the internal optical components can be directly seen from the outside, and the light uniformity of the whole lamp is not good.

Problems solved by technology

[0003] 1. In the traditional PAR lamp, the reflective surface of the lens is flat, the light emitted by the LED lamp bead is reflected neatly, and it is easy to image, and the yellow spot of the LED lamp bead is easy to appear. On the other hand, the lampshade is usually made of transparent or translucent glass lampshade , the internal optical components can be seen directly from the outside, and the light uniformity of the whole lamp is not good

[0004] 2. For traditional PAR lights, the LED light board is usually fixed to the bottom of the aluminum cup by screws. To fix the LED light board and the aluminum cup with screws, it needs to be positioned first, and then screwed in. The assembly efficiency is low, which is not conducive to improving production efficiency

[0005] 3. Traditional PAR lamps usually use screws to fix the lens. The screws need to go through the LED lamp board and the aluminum cup. It is cumbersome to locate and then screw in the screws. The assembly efficiency is low, which is not conducive to improving production efficiency.

[0006] 4. For traditional PAR lamps, solid glue is usually used to fix the lamp holder and the shell. However, the lamp holder is usually threaded lamp holder or buckle lamp holder. These two lamp holders require knobs during installation and removal. The bonding force of solid glue is low, and the lamp head is easy to be unscrewed under improper force, causing damage to the entire PAR, etc.
