Problems solved by technology

[0003] The purpose of the present invention is to provide a light source with a small luminous area and a simulated flame to solve the problems of the existing electric fireplaces such as poor definition of the simulated flame of the electric fireplace, small contrast of the picture and serious atomization of the picture due to the large luminous area of ​​the light source. High-definition, high-contrast high-power LED light source electric fireplace
[0004] Another object of the present invention is to solve the problem that the existing electric fireplace has too large light source irradiation angle, and the images generated by the light rays of multiple light sources overlap with each other, resulting in poor definition of the simulated flame of the electric fireplace, low contrast of the picture and serious fogging of the picture. Provide a high-power LED light source electric fireplace with less overlap of light from multiple light sources, high definition of simulated flames, and high picture contrast

Embodiment 1

[0022] in as figure 1 In the illustrated embodiment 1, a high-power LED light source electric fireplace includes a casing 1, an imaging light source 2, a light processing device 3 and an imaging screen 4. The light processing device is horizontally arranged under the rear side of the electric fireplace casing. There is one imaging light source in the body, which is set in the middle of the lower part of the imaging screen on the front side of the electric fireplace. The imaging light source is a 10-watt high-power LED point light source, the color temperature of the high-power LED point light source is 5500K, and its light-emitting area is 2 square centimeter, the illumination angle α is 120 degrees (see figure 2 ).

Embodiment 2

[0024] in as image 3 In the second embodiment shown, there are two imaging light sources, which are arranged in the horizontal direction. The imaging light source is a 6-watt high-power LED point light source, the color temperature of the high-power LED point light source is 6000K, and the light-emitting area is 1.5 square centimeters. The irradiation angle α is 90 degrees, and the light processing device is a rotating shaft and a reflector 5 arranged on the rotating shaft. The rotating shaft includes a reflector clamping portion 6 and connecting shafts 7 at both ends, and the clamping portion includes two twisted Or wrap a twist-shaped clamping strip, the reflector is a flexible reflective sheet, the fixed end of the reflector is set between the two clamping strips, and more than 60% of the reflective surfaces or reflective spots on the light processing device are reflected. All of the light comes from the same high-power LED point light source, and the rest are the same as ...

Embodiment 3

[0026] in as Figure 4 In the embodiment 2 shown, there are 5 imaging light sources, the imaging light source is a 4-watt high-power LED point light source, the color temperature of the high-power LED point light source is 5000K, the light-emitting area is 1 square centimeter, and the illumination angle α is 70 degrees, the light reflected by more than 70% of the reflective surfaces or reflective points on the light processing device all come from the same high-power LED point light source, and the rest are the same as in Example 1.

Abstract

The invention discloses a high-power LED light source electric fireplace which comprises a shell, imaging light sources, a light processing device and an imaging screen. The high-power LED light source electric fireplace is characterized in that the shell is internally provided with one to ten imaging light sources which are high-power LED point light sources of 1-10 watts. The high-power LED light source electric fireplace effectively solves the problems of poor definition of electric fireplace simulate fire, small picture contrast and severe picture atomization caused by large light-emitting areas of the light sources of the prior electric fireplace. The high-power LED light source electric fireplace has clear and vivid fire, distinct picture brightness, strong autokinetic effect and large contrast, greatly improves the aesthetic effect of the electric fireplace, enhances the art infection of fire pictures of the electric fireplace and has obvious economic benefit.

Description

technical field [0001] The invention relates to a simulated fireplace, in particular to an electric fireplace with a high-power LED light source. Background technique [0002] Electric fireplaces in the prior art mostly use incandescent lamps as imaging light sources, but incandescent lamps have high energy consumption and low luminous efficiency, and do not meet the requirements of energy conservation and environmental protection in today's increasingly scarce energy sources. Therefore, some people have developed electric fireplaces that use LEDs as imaging light sources. The patent document with the publication date of April 23, 2008 and the publication number of CN201050823Y discloses an electric fireplace with LED light source, which includes a casing of the electric fireplace, an imaging screen arranged vertically in the middle, and a front of the imaging screen is provided with an electric fireplace. The simulated charcoal is provided with a reflective shaft at the re...
