Description

A kind of LED lamp with PC transparent cover

【Technical field】

The utility model mainly relates to an LED lamp with a PC light-transmitting cover.

【Background technique】

With the development of social economy and the improvement of people's living standards, people's requirements for commercial space are also getting higher and higher. Lighting is one of the important components of store space, and lighting design can attract and guide consumers' eyes. Through the shaping of the space light environment, create a fascinating display space and display image, use a variety of lighting methods to display the theme image of the store, make people associate, arouse the resonance of consumers, and establish emotional exchanges with consumers.

LED (Light Emitting Diode, Light Emitting Diode) technology has been widely promoted for its advantages of power saving, high brightness, long service life, and good shock resistance. In recent years, LED lights have become more and more widely used in daily lighting and displays. However, because the white light emitted by the LED lamp contains more blue light components, people's visual experience is not very natural under the illumination of this light, and the light emitted by the LED lamp is more dazzling and easily causes glare. Moreover, the LED lamp is a point-shaped light source, and the heat generated by it is also concentrated in a very small area. If the generated heat cannot be dissipated in time, it will directly affect the service life and luminous effect of the LED lamp. In addition, for lamps and lanterns, high light transmittance often produces glare or even light pollution for illuminants with small light emitting surfaces and high light intensity. The conventional method is to use a translucent cover to reduce the light intensity. To improve the glare problem, but also lost nearly 20% of the luminous flux. Light transmittance and anti-glare are a pair of contradictions. For the performance of the light-transmitting cover, how to achieve high light transmittance and anti-glare at the same time is always a problem, and it is difficult to balance. At present, the LED lamps on the market generally have low light transmittance, poor lighting effect, and no heat dissipation effect. At the same time, the products with good light transmittance are expensive, and it is difficult for consumers to distinguish the pros and cons of the products. defect.

As disclosed in Chinese Patent No. (CN201320590817.X), an LED lamp with an acrylic light guide plate includes a side-emitting flat-panel lighting module and a direct-type flat-panel lighting module. The side-emitting flat-panel lighting module includes an outer frame and is fixed to the outer frame The strip-shaped light source inside, the acrylic light guide plate used to convert the strip-shaped light source into a plane light source, and the diffuser plate used to scatter and diffuse the plane light; The backboard and the plane fixed on the backboard; the direct-type flat-panel lighting module is fixed on the inner frame of the side-emitting flat-panel lighting module. This kind of LED uses an acrylic light guide plate as a light-transmitting lampshade, but acrylic production is difficult and costly, so there are many low-quality and low-cost substitutes on the market. These substitutes are also called "acrylic", which are actually ordinary organic boards or composite boards (also known as sandwich boards). Ordinary plexiglass is casted with ordinary plexiglass pyrolysis material and pigment, the surface hardness is low, easy to fade, and the polishing effect is poor after grinding with fine sand. The composite board has only a thin layer of acrylic on the surface, and ABS plastic in the middle, which is easy to delaminate due to thermal expansion and contraction during use. The average consumer has little experience in choosing, resulting in often buying the wrong product.

As disclosed in Chinese Patent No. (CN201280073902.7), a LED lighting module includes: a frame with a receiving groove in its lower part; a base fixed on the inner mounting surface of the receiving groove of the frame, and has A plurality of LED packages above; a plurality of cooling fins arranged on the upper surface and side surfaces of the frame and separated from each other; and a fixed part protruding from the upper surface of the frame, the lower part of which has a Coupling holes for coupling substrates and bolts, but this module requires more materials to manufacture multiple heat dissipation fins for heat dissipation, which leads to an increase in production costs and also increases the difficulty of production.
