Example Embodiment

[0014] figure 1 It is a schematic diagram of the structure of the reflective curved LED lamp of the present invention.

[0015] Combine figure 1 with figure 2 To further explain the present invention

[0016] figure 2 It is a schematic diagram of the principle of the reflective curved LED lamp of the present invention. The reflective curved LED lamp includes a reflective device, a light-emitting device and a heat sink. The reflective device is composed of a reflective film 10 and a transparent protective cover 11. That is, the reflective film 10 is plated on the transparent protective cover 11 so that its wavelength During the period of 400nm-700nm, 98% of the light is reflected back. At the same time, the reflective film 10 can be plated on the inner surface of the transparent protective cover 11 as required. The reflective surface of the reflective device can be spherical, secondary and high-order aspherical surfaces, free-form surfaces, etc.; the light-emitting device include...

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...
