Description

technical field [0001] The invention relates to an electric lamp, in particular to a high-power light-emitting diode electric lamp for lighting purposes. Background technique [0002] Light-emitting diodes (LEDs) have been widely used in decorative lights (such as underwater lights) and indicator lights (such as traffic lights) due to their long life, power saving, and environmental protection without causing environmental pollution. However, due to the low unit output power The resulting problems such as insufficient luminous brightness, poor heat dissipation efficiency, and insufficient lighting angle make LEDs unsuitable for lighting applications. With the improvement of white LEDs, the luminous brightness generated under the unit output power has gradually increased, which has solved the problem of insufficient brightness. White LEDs with luminous brightness exceeding the luminous brightness of traditional incandescent hot bulbs (301m / W) have been commercialized. The co...

[0007] Another shortcoming of the high-power LED lamp 148 is high light loss. This is because after the light emitted by the high-power LED 124 is reflected many times in the reflector cup 150, a part of it cannot become projected light, and when the light passes through the lens sheet 152 , and part of it is reflected back into the reflective cup 150, thus reducing the effective light utilization rate of the high-power LED lamp 148

[0008] Figure 11 It is the light distribution curve diagram of the traditional incandescent bulb, showing that the illumination angle with a luminous brightness ratio above 60% is 280°, while figure 1 2 is the light distribution curve of a typical high-power LED, which shows that the lighting angle with a luminous brightness ratio above 60% is 110°. Therefore, another problem to be solved for high-power LEDs in lighting applications is insufficient lighting angle. Unable to achieve ambient lighting which requires wide and uniform light, that is, to solve the problem of insufficient lighting angle in optical design, in order to create a new opportunity for high-power LEDs to be used in lighting applications
