Reflective curved surface LED lamp

Abstract

The invention provides a reflective curved surface LED lamp which comprises a reflecting device, a light-emitting device and a heat radiating device, wherein the reflecting device is a transparent protective cover 11 plated with a reflective film 10; and the light-emitting device consists of a light-emitting chip 5, a substrate 4, a leading wire 3 and a leading wire support 2, the whole light-emitting device is placed in a solid lens 1 molded by one-time plastic injection, the light-emitting chip 5, the leading wire 3, one end of the leading wire support 2, the inner surface of the substrate 4 and the like are wrapped in the solid lens 1, and the heat radiating device comprises a semiconductor refrigeration piece 7 and a heat radiating sheet 6. The heat radiating device is mounted on the outer surface of the substrate, and the whole light-emitting device and the heat radiating device are arranged on the lower surface of the reflecting device. The reflective curved surface LED lamp can solve the technical problems that divergent light with large angle is converged in a smaller range, thereby leading the radiation distance to be farther and leading the positioning of a light beam to be better. The requirements on the structure and materials of the reflective curved surface LED lamp are very simple, thereby being easy to carry out large-scale production and realizing broad prospects.

Description

technical field [0001] The invention belongs to an LED lamp, in particular to a reflective curved surface LED lamp. Background technique [0002] LED technology is a new energy-saving technology for semiconductor diode light-emitting lighting. LED lights have the characteristics of small size, light weight, can withstand high-intensity mechanical shock and vibration, not easy to break, safe and environmentally friendly, short response time, energy saving, long life, and high luminous efficiency. Therefore, There are various types and uses of LED lights. Since the light emitted by the light-emitting chip of the LED lamp is divergent light, according to the needs of the application, it is necessary to shape the light during application. In some occasions, in order to allow the light to irradiate a longer distance, the emitted beam is required to be very narrow. In the prior art, the application number is 200310111977.2 of the LED lamp. This invention adopts light shaping and...

Moreover, the scope of application is also limited. This method lacks practical economic benefits and is difficult to achieve

The LED lamp with the application number of 200410078393.4 uses a layer of reflective film electroplated on the metal lamp cup to increase the light intensity, but the light it emits is still divergent light, and the irradiation distance is not far enough
